3 [Remove entries to the current 2.0 section below, when backported]
5 *) Removed old and unmaintained ap_add_named_module API and changed
6 the following APIs to return an error instead of hard exiting:
7 ap_add_module, ap_add_loaded_module, ap_setup_prelinked_modules,
8 and ap_process_resource_config. [André Malo]

51 argument is not recognized as an URL, assume it's a mail address.
52 PR 28174. [André Malo]
54 *) mod_rewrite no longer confuses the RewriteMap caches if
55 different maps defined in different virtual hosts use the
56 same map name. PR 26462. [André Malo]

88 *) mod_cgid: Don't allow Scriptsock to be specified inside VirtualHost;
89 Don't place script socket inside default server root instead of
90 actual server root. PR 27886. [Jeff Trawick]
92 *) work around MSIE Digest auth bug - if AuthDigestEnableQueryStringHack
93 is set in r->subprocess_env allow mismatched query strings to pass.
94 PR 27758. [Paul Querna <chip force-elite.com>, Geoffrey Young]
96 *) mod_dav: Fix a problem that could cause crashes when manipulating

116 never worked at all. PR 25725. [André Malo]
118 *) minor mod_auth_basic and mod_auth_digest sync. mod_auth_basic
119 now populates r->user with the (possibly unauthenticated) user,
120 and mod_auth_digest returns 500 when a provider returns
124 *) mod_isapi: GetServerVariable returned improperly terminated header
125 fields given "ALL_HTTP" or "ALL_RAW". PR 20656.
126 [Jesse Pelton <jsp pkc.com>]
128 *) mod_isapi: send_response_header() failed to copy status string's
129 last character. PR 20619. [Jesse Pelton <jsp pkc.com>]
131 *) mod_isapi: GetServerVariable("ALL_RAW") returned the wrong buffer
132 size. PR 20617. [Jesse Pelton <jsp pkc.com>]

147 *) Add core version query function (ap_get_server_revision) and
148 accompanying ap_version_t structure (minor MMN bump).
151 *) mod_rewrite: EOLs sent by external rewritemaps are now consumed
152 as whole. That way, on systems with more than one EOL character
153 rewritemap programs no longer need to switch stdout to binary

181 *) mod_proxy with ProxyErrorOverride On in a reverse-proxy configuration attaches
182 a body to the 302 response and a wrong Content-Length header.
183 PR: 22951 [Ermanno Scaglione scaglione ..at.. starnetone.de]
185 *) Bring ErrorHeader concept forward from 1.3, so that response
186 header fields can be set for return even on errors or external
187 redirects. [Ken Coar]

213 filesystem name are rejected with 403. [Jeff Trawick]
215 *) Switch to APR 1.0 API.
217 *) Major overhaul of mod_include's filter parser. The new parser code
218 is expected to be more robust and should catch all of the edge cases
219 that were not handled by the previous one. This includes a binary
220 incompatible change of mod_include's external API. [André Malo]
222 *) mod_rewrite: Allow forced mimetypes [T=...] to get expanded.
223 PR 14223. [André Malo]
225 *) mod_rewrite: Fix LA-U and LA-F lookups in directory context. Previously
226 the current rewrite state was just used as lookup path, which lead to

269 *) Fix a compile failure with recent OpenSSL and picky compilers
270 (e.g., OpenSSL 0.9.7a and xlc_r on AIX). [Jeff Trawick]
272 *) OpenSSL headers should be included as "openssl/ssl.h", and not rely on
273 the INCLUDE path to be defined properly.
274 PR 11310. [Geoff Thorpe <geoff geoffthorpe.net>]
276 *) Modify APACHE_CHECK_SSL_TOOLKIT to detect SSL-C. [Madhusudan Mathihalli]

282 *) change directive name from 'compressionlevel' to 'deflatecompressionlevel'
283 [Ian Holsman, André Malo]
285 *) mod_negotiation: quality values are now parsed independent from
286 the current locale. level values are now really parsed as integers.
287 PR 17564. [André Malo]
289 *) Extend mod_negotiation to evaluate the environment variables
290 no-gzip and gzip-only-text/html the same way as mod_deflate does.
293 *) mod_rewrite: Fix some problems reporting errors with mapping
294 programs (RewriteMap prg:/something). [Jeff Trawick]
296 *) Return 413 if chunk-ext-header is too long rather than reading from
297 the truncated line. PR 15857. [Justin Erenkrantz]
299 *) Allow restart of httpd to occur even with syntax errors in the config
300 file. PR 16813. [Justin Erenkrantz]
302 *) Use APR_LAYOUT instead of APACHE_LAYOUT in configure. PR 15679.
305 *) Remove files on 'make distclean' that should be. PR 15592.
308 *) Allow apachectl to perform status with links and elinks as well.
311 *) Extend the SetEnvIf directive to capture subexpressions of the
312 matched value. [André Malo]
314 *) mod_log_config change optional hook to return previous handler
317 *) Forward port of mod_actions' ability to handle arbitrary methods
318 with the Script directive. [André Malo]
320 *) Let suexec send a message to stderr, if it failed or its policy
321 was violated. This message appears in the error log and allows
322 for easier debugging. PR 5381, 7638, 8255, 10773. [André Malo]
324 *) Modify buildconf to copy all required files into httpd's tree.
325 [Thom May <thom planetarytramp.net>]
327 *) Allow mod_dav to do weak entity comparison functions.
330 *) Move RFC 1413 ident requests from core to new module mod_ident.

340 *) Replace some of the mutex locking in the worker MPM with
341 atomic operations for higher concurrency. [Brian Pane]
343 *) Allow 'make depend' to work with non-GCC compilers.
346 *) If an httpd.conf has commented out AddModule directives,
347 apxs -i -a will add an un-commented AddModule directive for
348 the new module, which breaks the config.
349 PR: 11212 [Joe Orton]
351 *) Fix mod_proxy handling of filtered input bodies. [Justin Erenkrantz]
353 *) Move the check of the Expect request header field after the hook
354 for ap_post_read_request, since that is the only opportunity for
355 modules to handle Expect extensions. [Justin Erenkrantz]
357 *) Rewrite of aaa modules to an authn/authz model.
358 [Dirk-Willem van Gulik, Justin Erenkrantz]
361 [Apache 2.1.0-dev includes those bug fixes and changes with the
362 Apache 2.0.xx tree as documented, and except as noted, below.]
364 Changes with Apache 2.0.50

392 *) Fix crash when Apache was started with no Listen directives.
393 [Michael Corcoran <mcorcoran warpsolutions.com>]
395 *) core_output_filter: Fix bug that could result in sending
396 garbage over the network when module handlers construct
397 bucket brigades containing multiple file buckets all referencing
398 the same open file descriptor. [Bojan Smojver]
400 *) Fix memory corruption problem with ap_custom_response() function.
401 The core per-dir config would later point to request pool data
402 that would be reused for different purposes on different requests.
403 [Jeff Trawick, based on an old 1.3 patch submitted by Will Lowe]
405 *) Win32: Tweak worker thread accounting routines to eliminate
406 server hang when number of Listen directives in httpd.conf

412 *) SECURITY: CAN-2004-0174 (cve.mitre.org)
413 Fix starvation issue on listening sockets where a short-lived
414 connection on a rarely-accessed listening socket will cause a
415 child to hold the accept mutex and block out new connections until
416 another connection arrives on that rarely-accessed listening socket.
417 With Apache 2.x there is no performance concern about enabling the
418 logic for platforms which don't need it, so it is enabled everywhere
419 except for Win32. [Jeff Trawick]
421 *) mod_cgid: Fix storage corruption caused by use of incorrect pool.
424 *) Win32: find_read_listeners was not correctly handling multiple
425 listeners on the Win32DisableAcceptEx path. [Bill Stoddard]

431 failed" messages during restart and problem with the logger
432 respawning again after Apache is stopped. PR 21648, PR 24805.
435 *) Fixed file extensions for real media files and removed rpm extension
436 from mime.types. PR 26079. [Allan Sandfeld <kde carewolf.com>]
438 *) Remove compile-time length limit on request strings. Length is
439 now enforced solely with the LimitRequestLine config directive.

502 becoming negative. PR: 21285, 21287
503 [Bill Stoddard, Massimo Torquati, Jean-Jacques Clar]
505 *) core.c: If large file support is enabled, allow any file that is
506 greater than AP_MAX_SENDFILE to be split into multiple buckets.
507 This allows Apache to send files that are greater than 2gig.
508 Otherwise we run into 32/64 bit type mismatches in the file size.
511 *) proxy_http fix: mod_proxy hangs when both KeepAlive and
512 ProxyErrorOverride are enabled, and a non-200 response without a
513 body is generated by the backend server. (e.g.: a client makes a
514 request containing the "If-Modified-Since" and "If-None-Match"
515 headers, to which the backend server respond with status 304.)

533 *) mod_usertrack no longer overwrites other cookies.
534 PR 26002. [Scott Moore <apache nopdesign.com>]
536 *) worker MPM: fix stack overlay bug that could cause the parent
537 process to crash. [Jeff Trawick]
539 *) Win32: Add Win32DisableAcceptEx directive. This Windows
540 NT/2000/CP directive is useful to work around bugs in some
541 third party layered service providers like virus scanners,
542 VPN and firewall products, that do not properly handle
543 WinSock 2 APIs. Use this directive if your server is issuing
544 AcceptEx failed messages.

563 format code is used. PR 22741. [Gary E. Miller <gem rellim.com>]
565 *) Fix build with parallel make. PR 24643. [Joe Orton]
567 *) mod_rewrite: In external rewrite maps lookup keys containing
568 a newline now cause a lookup failure. PR 14453.
569 [Cedric Gavage <cedric.gavage unixtech.be>, André Malo]
571 *) Backport major overhaul of mod_include's filter parser from 2.1.
572 The new parser code is expected to be more robust and should
573 catch all of the edge cases that were not handled by the previous one.
574 The 2.1 external API changes were hidden by a wrapper which is
575 expected to keep the API backwards compatible. [André Malo]
577 *) Add a hook (insert_error_filter) to allow filters to re-insert
578 themselves during processing of error responses. Enable mod_expires
579 to use the new hook to include Expires headers in valid error
580 responses. This addresses an RFC violation. It fixes PRs 19794,
581 24884, and 25123. [Paul J. Reder]
583 *) Add Polish translation of error messages. PR 25101.
584 [Tomasz Kepczynski <tomek jot23.org>]

1159 was disabled. Needed to make sure that the code did not
1160 attempt to use the cache if it didn't exist. Also fixed some memory

1693 aside a small file for potential concatenation with the next
1694 response on the connection, set aside the file descriptor rather
1695 than copying the file into the heap. [Brian Pane]
1697 *) Modified version check on openssl so that it finds the executable
1698 first and then performs a check of the version, only warning the
1699 user if they chose, or we selected, an old version of OpenSSL.
1700 This change also allows the code to work for non-openssl libraries
1701 selected via the --with-ssl=dir option, which can override the
1702 automated library check in any case. [Roy Fielding]
1704 Changes with Apache 2.0.40
1706 *) SECURITY [CAN-2002-0661] (cve.mitre.org):
1707 Close a very significant security hole that
1708 applies only to the Win32, OS2 and Netware platforms. Unix was not
1709 affected, Cygwin may be affected. Certain URIs will bypass security
1710 and allow users to invoke or access any file depending on the system
1711 configuration. Without upgrading, a single .conf change will close
1712 the vulnerability. Add the following directive in the global server
1713 httpd.conf context before any other Alias or Redirect directives;
1714 RedirectMatch 400 "\\\.\."
1715 Reported by Auriemma Luigi <bugtest sitoverde.com>.
1718 *) SECURITY [CAN-2002-0654] (cve.mitre.org):
1719 Close a path-revealing exposure in multiview type
1720 map negotiation (such as the default error documents) where the
1721 module would report the full path of the typemapped .var file when
1722 multiple documents or no documents could be served based on the mime
1723 negotiation. Reported by Auriemma Luigi <bugtest sitoverde.com>.
1726 *) SECURITY [CAN-2002-0654] (cve.mitre.org):
1727 Close a path-revealing exposure in cgi/cgid when we
1728 fail to invoke a script. The modules would report "couldn't create
1729 child process /path-to-script/script.pl" revealing the full path
1730 of the script. Reported by Jim Race <jrace qualys.com>.
1733 *) Set aside the apr-iconv and apr_xlate() features for the Win32
1734 build of 2.0.40 so development can be completed. A patch, from
1735 <http://www.apache.org/dist/httpd/patches/apply_to_2.0.40/>
1736 will be available for those that wish to work with apr-iconv.
1739 *) Fix proxy so that it is possible to access ftp: URLs via a proxy
1740 chain. [Peter Van Biesen <peter.vanbiesen vlafo.be>]
1742 *) mod-deflate now checks to make sure that 'gzip-only-text/html' is
1743 set to 1, so we can exclude things from the general case with
1744 browsermatch. [Ian Holsman, Andre Schild <A.Schild aarboard.ch>]
1746 *) Accept multiple leading /'s for requests within the DocumentRoot.
1747 PR 10946 [William Rowe, David Shane Holden <dpejesh yahoo.com>]
1749 *) Solved the reports of .pdf byterange failures on Win32 alone.
1750 APR's sendfile for the win32 platform collapses header and trailer
1751 buffers into a single buffer. However, we destroyed the pointers
1752 to the header buffer if a trailer buffer was present. PR 10781
1755 *) mod_ext_filter: Add the ability to enable or disable a filter via
1756 an environment variable. Add the ability to register a filter of
1757 type other than AP_FTYPE_RESOURCE. [Jeff Trawick]
1759 *) Restore the ability to specify host names on Listen directives.
1760 PR 11030. [Jeff Trawick, David Shane Holden <dpejesh yahoo.com>]
1762 *) When deciding on the default address family for listening sockets,
1763 make sure we can actually bind to an AF_INET6 socket before
1764 deciding that we should default to AF_INET6. This fixes a startup
1765 problem on certain levels of OpenUNIX. PR 10235. [Jeff Trawick]
1767 *) Replace usage of atol() to parse strings when we might want a
1768 larger-than-long value with apr_atoll(), which returns long long.
1769 This allows HTTPD to deal with larger files correctly.
1770 [Shantonu Sen <ssen apple.com>]
1772 *) mod_ext_filter: Ignore any content-type parameters when checking if
1773 the response should be filtered. Previously, "intype=text/html"
1774 wouldn't match something like "text/html;charset=8859_1".
1777 *) mod_ext_filter: Set up environment variables for external programs.
1778 [Craig Sebenik <craig netapp.com>]
1780 *) Modified the HTTP_IN filter to immediately append the EOS (end of
1781 stream) bucket for C-L POST bodies, saving a roundtrip and allowing
1782 the caller to determine that no content remains without prefetching
1783 additional POST body. [William Rowe]
1785 *) Get proxy ftp to work over IPv6. [Shoichi Sakane <sakane kame.net>]
1787 *) Look for OpenSSL libraries in /usr/lib64. [Peter Poeml <poeml suse.de>]
1789 *) Update SuSE layout. [Peter Poeml <poeml suse.de>]
1791 *) Changes to the internationalized error documents:
1792 Comment them out in the default config file to make the default
1793 install as simple as possible; Correct the english 500 error to
1794 be more understandable; Add a Swedish translation.
1795 [Thomas Sjogren <thomas northernsecurity.net>,
1796 Erik Abele <erik codefaktor.de>, Rich Bowen, Joshua Slive]
1798 *) Increase the limit on file descriptors per process in apachectl.
1801 *) Fix a dependency error when building ApacheMonitor, so that Win32
1802 and MSVC now trust that the project is current (when it is).
1803 [James Cox <imajes php.net>]
1805 *) mod_ext_filter: don't segfault if content-type is not set. PR 10617.
1806 [Arthur P. Smith <apsmith aps.org>, Jeff Trawick]
1808 *) APR-Util Renames pending have been completed [Thom May]
1810 *) Performance improvements for the code that reads request
1811 headers (ap_rgetline_core() and related functions) [Brian Pane]
1813 *) Add a new directive: MaxMemFree. MaxMemFree makes it possible
1814 to configure the maximum amount of memory the allocators will
1815 hold on to for reuse. Anything over the MaxMemFree threshold
1816 will be free()d. This directive is useful when uncommon large
1817 peaks occur in memory usage. It should _not_ be used to mask
1818 defective modules' memory use. [Sander Striker]
1820 *) Fixed the Content-Length filter so that HTTP/1.0 requests to CGI
1821 scripts would not result in a truncated response.
1822 [Ryan Bloom, Justin Erenkrantz, Cliff Woolley]
1824 *) Add a filter_init parameter to the filter registration functions
1825 so that a filter can execute arbitrary code before the handlers
1826 are invoked. This resolves a problem where mod_include requests
1827 would incorrectly return a 304. [Justin Erenkrantz]
1829 *) Fix a long-standing bug in 2.0, CGI scripts were being called
1830 with relative paths instead of absolute paths. Apache 1.3 used
1831 absolute paths for everything except for SuExec, this brings back
1832 that standard. [Ryan Bloom]
1834 *) Fix infinite loop due to two HTTP_IN filters being present for
1835 internally redirected requests. PR 10146. [Justin Erenkrantz]
1837 *) Switch conn_rec->keepalive to an enumeration rather than a bitfield.
1840 *) Fix mod_ext_filter to look in the main server for filter definitions
1841 when running in a vhost if the filter definition is not found in
1842 the vhost. PR 10147 [Jeff Trawick]
1844 *) Support WinNT CGI invocation through ScriptInterpreterSource
1845 'registry' for script interpreter paths and names with non-ascii
1846 characters in the executable filepath. [William Rowe]
1848 *) Support the -w flag on to keep the Win32 console open on error.
1851 *) Normalize the hostname value in the request_rec to all-lowercase
1852 [Perry Harrington <pedward webcom.com>]
1854 *) Fix WinNT cgi 500 errors when QUERY_ARGS or other strings include
1855 extended characters (non US-ASCII) in non-utf8 format. This brings
1856 Win32 back into CGI/1.1 compliance, and leaves charset decoding up
1857 to the cgi application itself. [William Rowe]
1859 *) Major overhaul of mod_dav, mod_dav_fs and the experimental/cache
1860 modules to bring them up to the current apr/apr-util APIs.
1863 *) Fix segfault in mod_mem_cache most frequently observed when
1864 serving the same file to multiple clients on an MP machine.
1867 *) mod_rewrite can now set cookies (RewriteRule (.*) - [CO=name:$1:.domain])
1868 [Brian Degenhardt <bmd mp3.com>, Ian Holsman]
1870 *) Fix perchild to work with apachectl by adding -k support to perchild.
1871 PR 10074 [Jeff Trawick]
1873 *) Fix a silly htpasswd.c logic error that incorrectly reported that
1874 both -c and -n had been used. PR 9989 [Cliff Woolley]
1876 *) Fixed a mod_include error case in which no HTTP response was sent
1877 to the client if an shtml document contained an unterminated SSI
1878 directive [Brian Pane]
1880 *) Improve ap_get_client_block implementation by using APR-util brigade
1881 helper functions and relying on current filter assumptions.
1884 Changes with Apache 2.0.39
1886 *) Fixed a build problem in htpasswd.c on Win32.
1887 [Guenter Knauf <eflash gmx.net>, Cliff Woolley]
1889 Changes with Apache 2.0.38
1891 *) Rewrite htpasswd to use APR. The removes the annoying warning about
1892 tmpnam being unsafe. [Ryan Bloom]
1894 *) We must set the MIME-type for .shtml files to text/html if we want them
1895 to be parsed for SSI tags. Add the config for that to the default
1896 config file so that it is easier to enable .shtml parsing.
1897 [Dave Dyer <ddyer real-me.net>]
1899 *) Fixed a problem with 'make install' on ReliantUnix.
1900 [Jean-frederic Clere <jfrederic.clere fujitsu-siemens.com>]
1902 *) Make the default_handler catch all requests that aren't served by
1903 another handler. This also gets us to return a 404 if a directory
1904 is requested, there is no DirectoryIndex, and mod_autoindex isn't
1905 loaded. [Justin Erenkrantz]
1907 *) Fixed the handling of nested if-statements in shtml files.
1908 PR 9866 [Brian Pane]
1910 *) Allow 'make install DESTDIR=/path'. This allows packagers to install
1911 into a directory different from the one that was configured. This
1912 also mirrors the root= feature from 1.3. We cannot use prefix=,
1913 because both APR and APR-util resolve their installation paths at
1914 configuration time. This means that there is no variable prefix
1915 to replace. [Andreas Hasenack <andreas netbank.com.br>]
1917 *) AIX 4.3.2 and above: Define SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1918 These levels of AIX don't have a thundering herd problem with
1919 accept(). [Jeff Trawick]
1921 *) prefork MPM: Ignore mutex errors during graceful restart. For
1922 certain types of mutexes (particularly SysV semaphores), we
1923 should expect to occasionally fail to obtain or release the
1924 mutex during restart processing. [Jeff Trawick]
1926 *) Fix install-bindist.sh so that it finds any perl instead of just
1927 early perl 5.x versions. This is consistent with a build/install
1928 from source, and it allows the perl scripts installed by a bindist
1929 to work on systems with perl 5.6. [Jeff Trawick]
1931 *) Fix apxs so that the makefile created by "apxs -g" works on AIX and
1932 Tru64 (and probably some other platforms). [Jeff Trawick]
1934 *) Allow CGI scripts to return their Content-Length. This also fixes a
1935 hang on HEAD requests seen on certain platforms (such as FreeBSD).
1938 *) Added log rotation based on file size to the RotateLog support
1939 utility. [Brad Nicholes]
1941 *) Fix some casting in mod_rewrite which broke random maps.
1942 PR 9770 [Allan Edwards, Greg Ames, Jeff Trawick]
1944 Changes with Apache 2.0.37
1946 *) allow POST method over SSL when per-directory client cert
1947 authentication is used with 'SSLOptions +OptRenegotiate' enabled
1948 and a client cert was found in the ssl session cache.
1950 *) 'SSLOptions +OptRengotiate' will use client cert in from the ssl
1951 session cache when there is no cert chain in the cache. prior to
1952 the fix this situation would result in a FORBIDDEN response and
1953 error message "Cannot find peer certificate chain"
1956 *) ap_finalize_sub_req_protocol() shouldn't send an EOS bucket if
1957 one was already sent. PR 9644 [Jeff Trawick]
1959 *) Fix the display of the default name for the mime types config
1960 file. PR 9729 [Matthew Brecknell <mbrecknell orchestream.com>]
1962 *) Fix the working directory *for WinNT/2K/XP services only* to
1963 change to the Apache directory (one level above the location
1964 of Apache.exe, in the case that Apache.exe resides in bin/.)
1965 Solves the case of ServerRoot /foo paths where /foo was not
1966 on the same drive as /winnt/system32. [William Rowe]
1968 *) Make 2.0's "AcceptMutex" startup message now "completely"
1969 match how 1.3 does it. [Jim Jagielski]
1971 *) Implement a fixed size memory cache using a priority queue
1974 *) Fix apxs to allow "apxs -q installbuilddir" and to allow
1975 querying certain other variables from config_vars.mk. PR 9316
1978 *) Added the "detached" attribute to the cgi_exec_info_t internals
1979 so that Win32 and Netware won't create a new window or console
1980 for each CGI invoked. PR 8387
1981 [Brad Nicholes, William Rowe]
1983 *) Consolidated the command line parameters and attributes that are
1984 manipulated by the optional function ap_cgi_build_command() in
1985 mod_cgi into a single structure.
1988 *) Get rid of uninitialized value errors with "apxs -q" on certain
1989 variables. [Stas Bekman <stas stason.org>]
1991 *) Fix apxs to allow it to work when the build directory is somewhere
1992 besides server-root/build. PR 8453
1993 [Jeff Trawick and a host of others]
1995 *) Allow ap_discard_request_body to be called multiple times in the
1996 same request. Essentially, ap_http_filter keeps track of whether
1997 it has sent an EOS bucket up the stack, if so, it will only ever
1998 send an EOS bucket for this request.
1999 [Ryan Bloom, Justin Erenkrantz, Greg Stein]
2001 *) Remove all special mod_ssl URIs. This also fixes the bug where
2002 redirecting (.*) will allow an SSL protected page to be viewed
2003 without SSL. [Ryan Bloom]
2005 *) Fix the binary build install script so that the build logic
2006 created by "apxs -g" will work when the user has a binary
2007 build. [Jeff Trawick]
2009 *) Allow instdso.sh to work with full paths to the shared module.
2012 *) NetWare: Enabled CGI functionality and added mod_cgi as a built
2013 in module for NetWare [Brad Nicholes]
2015 *) Changed cgi and piped log behavior to accept 65536 characters
2016 on Win32 (matching Linux) before deadlocking between outputing
2017 client stdin, slurping the output from stdout and then the stderr
2018 stream. PR 8179 [William Rowe]
2020 *) Fixed Win32 wintty.exe support to assure the window title is valid.
2021 Elimiates possible gpfault or garbage title without the -t option.
2024 *) Rewrite mod_cgi, mod_cgid, and mod_proxy input handling to use
2025 brigades and input filters. [Justin Erenkrantz]
2027 *) Allow ap_http_filter (HTTP_IN) to return EOS when there is no request
2028 body. [Justin Erenkrantz]
2030 *) NetWare: Piping log entries through RotateLogs using the
2031 CustomLogs directive is finally supported now that we have
2032 the pipes and spawning functionality working.
2035 *) SECURITY [CVE-2002-0392] (cve.mitre.org) [CERT VU#944335]:

2040 [James Tait <JTait wyrddreams.demon.co.uk>]
2042 *) Correctly return 413 when an invalid chunk size is given on
2043 input. Also modify ap_discard_request_body to not do anything
2044 on sub-requests or when the connection will be dropped.
2047 *) Fix the TIME_* SSL var lookups to be threadsafe. PR 9469.
2050 *) Ensure that apr_brigade_write() flushes in all of the cases that
2051 it should to avoid conditions in some modules that could cause
2052 large amounts of data to be buffered. [Cliff Woolley]
2054 *) Fix problem where mod_cache/mod_disk_cache was incorrectly
2055 stripping the content_type from cached responses.
2058 *) apachectl passes through any httpd options. Note: apachectl
2059 should be used in preference to httpd since it ensures that any
2060 appropriate environment variables have been set up.
2063 *) Fix the combination of mod_cgid, mod_setuexec, and mod_userdir.
2064 PR 7810 [Colm MacCarthaigh <colmmacc redbrick.dcu.ie>]
2066 *) Fix suexec execution of CGI scripts from mod_include.
2067 PR 7791, 8291 [Colm MacCarthaigh <colmmacc redbrick.dcu.ie>]
2069 *) Fix segfaults at startup on some platforms when mod_auth_digest,
2070 mod_suexec, or mod_ssl were used as DSO's due to the way they
2071 were tracking the current init phase since DSO's get completely

2081 [Yoshiki Hayashi, Joshua Slive]
2083 *) Fix a file permissions problem which prevented mod_disk_cache
2084 from working on Unix. [Jeff Trawick]
2086 *) Add "-k start|restart|graceful|stop" support to httpd for the Unix
2087 MPMs. These have semantics very similar to the old apachectl
2088 commands of the same name. [Justin Erenkrantz, Jeff Trawick]

2102 *) If content-encoding is already present, do not run deflate (PR 9222)
2103 [Kazuhisa ASADA <kaz asada.sytes.net>]
2105 *) The APLOG_NOERRNO flag to ap_log_[r]error() is now deprecated.
2106 It is currently ignored and it will be removed in a future release
2107 of Apache. [Jeff Trawick]
2109 *) Removed documentation references to the no-longer-supported
2110 "make certificate" feature of mod_ssl for Apache 1.3.x. Test
2111 certificates, if truly desired, can be generated using openssl
2112 commands. PR 8724. [Cliff Woolley]
2114 *) Remove SSLLog and SSLLogLevel directives in favor of having
2115 mod_ssl use the standard ErrorLog directives. [Justin Erenkrantz]
2117 *) OS/390: LIBPATH no longer has to be manually uncommented in
2118 envvars to get apachectl to set up httpd properly. [Jeff Trawick]
2120 *) mod_isapi: All mod_isapi directives, excluding ISAPICacheFile,
2121 may now be specified to the <File/Directory > container, rather
2122 than by vhost. [William Rowe]
2124 *) mod_isapi: Experimental support for faux async support for ISAPI
2125 modules. [William Rowe]
2127 *) mod_isapi: Major refactoring of the code to rely on apr internals
2128 rather than MS APIs (using our own mod_isapi.h headers for ISAPI
2129 symbol definitions.) [William Rowe]
2131 *) mod_isapi: Fixed the return string length from GetServerVariable
2132 callback, it was not including the trailing null in the consumed
2133 buffer size. This was particularly bad for Delphi 6.0 users.

2238 *) More efficient pool recycling logic for the worker MPM [Brian Pane]
2240 *) Modify the worker MPM to not accept() new connections until
2241 there is an available worker thread. This prevents queued

2286 ap_uname2id. [Scott Lamb <slamb slamb.org>]
2288 *) Fix AcceptPathInfo. PR 8234 [Cliff Woolley]
2290 *) SECURITY: Added the APLOG_TOCLIENT flag to ap_log_rerror() to
2291 explicitly tell the server that warning messages should be sent
2292 to the client in addition to being recorded in the error log.
2293 Prior to this change, ap_log_rerror() always sent warning
2294 messages to the client. In one case, a faulty CGI script caused
2295 the server to send a warning message to the client that contained
2296 the full path to the CGI script. This could be considered a
2297 minor security exposure. [Bill Stoddard]
2299 *) mod_autoindex output when SuppressRules was specified would
2300 omit the first carriage return so the first item in the list
2301 would appear to the right of the column headings instead of
2302 underneath them. PR 8016 [David Shane Holden <dpejesh yahoo.com>]
2304 *) Moved the call to apr_mmap_dup outside the error branch so
2305 that it would actually get called. This fixes a core dump
2306 at init everytime you use the MMapFile directive. PR 8314
2309 *) Trigger an error when a LoadModule directive attempts to
2310 load a module which is built-in. This is a common error when
2311 switching from a DSO build to a static build. [Jeff Trawick]
2313 *) Change instdso.sh to use libtool --install everywhere and then
2314 clean up some stray files and symlinks that libtool leaves around
2315 on some platforms. This gets subversion building properly since
2316 it needed a re-link to be performed by libtool at install time,
2317 and the old instdso.sh logic to simply cp the DSO didn't handle
2318 that requirement. [Sander Striker]

2329 *) Fix segfault in mod_mem_cache when garabge collecting an expired
2330 cache entry. [Bill Stoddard]
2332 *) Introduced -E startup_logfile_name option to httpd to allow admins
2333 to begin logging errors immediately. This provides Win32 users
2334 an alternative to sending startup errors to the event viewer, and
2335 allows other daemon tool authors an alternative to logging to stderr.

2421 "<!--#" occurs at the very end of a bucket
2422 [Paul Reder, Brian Pane]
2424 *) worker, prefork, perchild, beos MPMs: Add -DFOREGROUND switch to
2425 cause the Apache parent process to run in the foreground (similar to
2426 -DNO_DETACH except that it doesn't switch session ids).
2429 *) Added support for Posix semaphore mutex locking (AcceptMutex posixsem)
2430 for those platforms that support it. If using the default
2431 implementation, this is between pthread and sysvsem in priority.
2432 This implies it's the new default for Darwin. [Jim Jagielski]
2434 *) AIX: Fix the syntax for setting the LDR_CNTRL and AIXTHREAD_SCOPE
2435 environment variables in the envvars file. [Jeff Trawick]
2437 *) worker MPM: Don't create a listener thread until we have a worker
2438 thread. Otherwise, in situations where we'll have to wait a while
2439 to take over scoreboard slots from a previous generation, we'll be
2440 accepting connections we can't process yet. [Jeff Trawick]

2468 *) Made AB's use of the Host: header rfc2616 compliant
2469 by Taisuke Yamada <tai iij.ad.jp> [Dirk-Willem van Gulik].
2471 *) The old, legacy (and unused) code in which the scoreboard was totally
2472 and completely contained in a file (SCOREBOARD_FILE) has been
2473 removed. This does not affect scoreboards which are *mapped* to
2474 files using named-shared-memory. [Jim Jagielski]
2476 *) Change bucket brigades API to allow a "bucket allocator" to be
2477 passed in at certain points. This allows us to implement freelists
2478 so that we can stop using malloc/free so frequently.
2479 [Cliff Woolley, Brian Pane]

2511 *) Remove the single-byte socket reads for CGI headers [Brian Pane]
2513 *) When a proxied site was being served, Apache was replacing
2514 the original site Server header with it's own, which is not
2515 allowed by RFC2616. Fixed. [Graham Leggett]
2517 *) Fix a mod_cgid problem that left daemon processes stranded
2518 in some server restart scenarios. [Jeff Trawick]
2520 *) Added exp_foo and rel_foo variables to config_vars.mk for
2521 all Apache and Autoconf path variables (like --sysconfdir,
2522 --sbindir, etc). exp_foo is the "expanded" version, which means
2523 that all internal variable references have been interpolated.
2524 rel_foo is the same as $exp_foo, only relative to $prefix if they
2525 share a common path. [Aaron Bannert]
2527 *) Fix some restart/terminate problems in the worker MPM. Don't
2528 drop connections during graceful restart. [Jeff Trawick]
2530 *) Change the header merging behaviour in proxy, as some headers
2531 (like Set-Cookie) cannot be unmerged due to stray commas in
2532 dates. [Graham Leggett]

2540 *) Upgraded PCRE library to latest version 3.9 [Brian Pane]
2542 *) Add accessor function to set r->content_type. From now on,

2559 stack, rather than buffering the response into memory. [Greg Stein]
2561 *) Fix a hang condition with graceful restart and prefork MPM
2562 in the situation where MaxClients is very high but
2563 much fewer servers are actually started at the time of the
2564 restart. [Jeff Trawick]
2566 *) Small performance fixes for mod_include [Brian Pane]
2568 *) Performance improvement for the error logger [Brian Pane]

2571 SINGLE_LISTEN_UNSERIALIZED_ACCEPT defined by default.
2572 according to sun people solaris 8+ doesn't have a thundering
2573 herd problem [Ian Holsman]
2575 *) Allow URIs specifying CGI scripts to include '/' at the end

2596 preprocessor directive in mod_file_cache)
2599 *) Add filehandle caching to mod_mem_cache. (see CACHE_FD

2609 *) Stop installing libtool for APR and tell APR where it should place
2610 its copy of libtool (via our installbuildpath layout variable).
2613 *) New directive ProxyIOBufferSize. Sets the size of the buffer used
2614 when reading from a remote HTTP server in proxy. [Graham Leggett]
2616 *) Modify receive/send loop in proxy_http and proxy_ftp so that
2617 should it be necessary, the remote server socket is closed before
2618 transmitting the last buffer (set by ProxyIOBufferSize) to the
2619 client. This prevents the backend server from being forced to hang
2620 around while the last few bytes are transmitted to a slow client.
2621 Fix the case where no error checking was performed on the final
2622 brigade in the loop. [Graham Leggett]
2624 *) Scrap CacheMaxExpireMin and CacheDefaultExpireMin. Change
2625 CacheMaxExpire and CacheDefaultExpire to use seconds rather than
2626 hours. [Graham Leggett, Bill Stoddard]
2628 *) New Directive SSIUndefinedEcho. to change the '(none)' echoed
2629 for a undefined variable. [Ian Holsman]
2631 *) Proxy HTTP and CONNECT: Keep trying other addresses from the DNS
2632 when we can't get a socket in the specified address family. We may
2633 have gotten back an IPv6 address first and yet our system is not
2634 configured to allow IPv6 sockets. [Jeff Trawick]

2641 [Dirk-Jan Faber <dirk-jan selwerd.nl>, Aaron Bannert,
2642 Thom May <thom planetarytramp.net>]
2644 *) Rename the filter ordering priorities. The recent filtering fixes
2645 have showcased problems with their usage. Therefore, we need to
2646 rename them to increase the clarity. (CONTENT->RESOURCE,
2647 HTTP_HEADER->CONTENT_SET/PROTOCOL) [Justin Erenkrantz]
2649 Changes with Apache 2.0.33
2651 *) Fix a problem in the new --enable-layout functionality where
2652 it wouldn't allow overrides from variables like --prefix,
2653 --bindir, etc. [Thom May <thom planetarytramp.net>]
2655 *) Fix a bug in the core input filter for AP_MODE_EXHAUSTIVE. It
2656 no longer hangs around waiting for the socket to close before

2659 *) rename apr_exploded_time_t to apr_time_exp_t (as per renames pending)
2660 [Thom May <thom planetarytramp.net>]
2662 *) Change mod_ssl to always do a full startup/teardown on restarts.
2663 this allows mod_ssl to be added to a server that is already
2664 running and makes it possible to add/change certs/keys after the
2665 server has been started. [Doug MacEachern]
2667 *) Introduce PassPhraseDialog "|/path/to/pipe" mechanism to mod_ssl.
2668 This pipe must be a bidirectional 'console' style relay, which
2669 mod_ssl prints all prompts to the pipe's stdin, and reads the
2670 passphrases from the pipe's stdout. [William Rowe]
2672 *) Fix bug where --sysconfdir and --localstatedir were being
2673 ignored. [Thom May <thom planetarytramp.net>, Aaron Bannert]
2676 *) Fix --enable-layout to work again. Caution: When specifying
2677 --enable-layout, common arguments like --prefix, --exec-prefix,
2678 etc. will be ignored and the settings from the layout will be
2679 used instead. [Thom May <thom planetarytramp.net>, Aaron Bannert]
2682 *) New Directive for mod_proxy: ProxyRemoteMatch. This provides
2683 regex pattern matching for the determination of which requests
2684 to use the remote proxy for. [Jim Jagielski]
2686 *) Fix CustomLog bytes-sent with HTTP 0.9. [Justin Erenkrantz]
2688 *) Prevent Apache from ignoring SIGHUP due to some lingering 1.3
2689 cruft in piped logs and rewritemap child processes.
2692 *) All instances of apr_lock_t have been removed and converted
2693 to one of the following new lock APIs: apr_thread_mutex.h,
2694 apr_proc_mutex.h, or apr_global_mutex.h. No new code should
2695 use the apr_lock.h API, as the old API will soon be deprecated.
2698 *) Merged in changes to mod_ssl up through 2.8.7-1.3.23.

2701 *) mod-include: make it handle flush'es and fix the 'false-alarm'
2702 [Justin Erenkrantz, Brian Pane, Ian Holsman]
2704 *) ap_get_*_filter_handle() functions to allow 3rd party modules

2706 lookup when adding filters to a request (via ap_add_*_filter_handle())
2707 [Ryan Morgan <rmorgan covalent.net>]
2709 *) Fix for multiple file buckets on Win32, where the first file
2710 bucket would cause the immediate closure of the socket on any
2711 non-keepalive requests. [Ryan Morgan <rmorgan covalent.net>]
2713 *) Correct Win32 failure of mmap of a segment beyond start of the
2714 file; fixes large SSL and similar transfers. [William Rowe]
2717 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
2718 multi-process mode to not "daemonize" while detaching from the
2719 controlling terminal. This is necessary for Apache to work with
2720 process-management tools like AIX's "System Resource Controller"
2721 as well as Dan Bernstein's "daemontools".
2722 [Jos Backus <josb cncdsl.com>, Aaron Bannert]
2724 *) Convert mod_auth_digest to use the new apr_global_mutex_t
2725 type. [Aaron Bannert]
2727 *) fix bug in mod-include where it wouldn't send a unmatched
2728 part if it was at the end of a bucket [Ian Holsman]
2730 *) worker MPM: Improve logging of errors with the interface between
2731 the listener thread and worker threads. [Jeff Trawick]
2733 *) Some browsers ignore cookies that have been merged into a
2734 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
2735 are now unmerged in the http proxy before being sent to the
2736 client. [Graham Leggett]
2738 *) Fix a problem with proxy where each entry of a duplicated
2739 header such as Set-Cookie would overwrite and obliterate the
2740 previous value of the header, resulting in multiple header
2741 values (like cookies) going missing.
2742 [Graham Leggett, Joshua Slive]

2770 *) Add reference counting to mod_mem_cache cache objects to
2771 better manage removing objects from the cache.
2774 *) Change the verbage on the ScoreBoardFile in our default configs.
2775 Also change the default to be commented out (unspecified) so we
2776 get anonymous shared memory by default. [Aaron Bannert]
2778 *) Implement new ScoreBoardFile directive logic. This affects how
2779 we create the scoreboard's shared memory segment. If the directive
2780 is present, a name-based segment is created. If the directive is
2781 not present, first an anonymous segment is created, and if that
2782 fails, a name-based segment is created from a file of the name
2783 DEFAULT_SCOREBOARD. This gives third-party applications the
2784 ability to access our scoreboard. [Aaron Bannert]
2786 *) Allow mod_deflate to work with non-GET requests and properly send
2787 Content-Lengths. [Sander Striker <striker apache.org>]
2789 *) Fix ap_directory_merge() to correctly merge configs when there is
2790 no <Directory /> block. [Justin Erenkrantz, William Rowe]
2792 *) Remove spurious debug messsages that are normal under HTTP
2793 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
2795 *) Fix a bug in mod_cgid that would prevent proper shutdown death
2796 of the cgid process. [Aaron Bannert]
2798 *) Add signal handling back in to the worker MPM for the one_process
2799 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
2801 *) Performance: Reuse per-connection transaction pools in the
2802 worker MPM, rather than destroying and recreating them. [Brian Pane]
2804 *) Remove all signals from the worker MPM's child process. Instead,
2805 the parent uses the Pipe of Death for all communication with the
2806 child processes. [Ryan Bloom]
2808 Changes with Apache 2.0.32
2810 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
2811 default if the directive is not specified. This mirrors older
2812 behavior without changes to the httpd.conf. [William Rowe]
2814 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
2815 the service, mpm and logging code, and bugs in apr_file_open_stderr
2816 and apr_file_dup2 functions. Win2K/XP services have no handles
2817 associated for stdin/out/err, which caused unpredictable behavior
2818 in the prior release. [William Rowe, Bill Stoddard]
2820 *) Win32: simplify the Application Event Log messages, since there isn't
2821 likely to be 'more information in the error log' before an error log
2822 has been opened. [William Rowe]
2824 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
2825 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
2827 *) Win32: apache -k shutdown now behaves like apache -k stop.
2830 *) Fix prefork to not kill the parent if a child hits a resource shortage
2831 on accept(). [Greg Ames]
2833 *) Fix seg faults that occur when what should be the httpd request line
2834 starts with \r\n followed by garbage. [Greg Ames]
2836 *) Allow statically linked support binaries with the new
2837 --enable-static-support flag, and enable this behavior in
2838 the binbuild script. Also add a new --enable-static-htdbm
2839 flag. [Aaron Bannert]
2841 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
2842 do only one stat() call when generating the directory listings.
2845 *) Fix resolve_symlink to save the original symlink name if known.
2848 *) Be a bit more sane with regard to CanonicalNames. If the user has
2849 specified they want to use the CanonicalName, but they have not
2850 configured a port with the ServerName, then use the same port that
2851 the original request used. [Ryan Bloom and Ken Coar]
2853 *) In core_input_filter, check for an empty brigade after
2854 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
2855 client says it will post some data but we get FIN before any
2856 data arrives. [Jeff Trawick]
2858 *) Not being able to bind to the socket is a fatal error. We should
2859 print an error to the console, and return a non-zero status code.
2860 With these changes, all of the Unix MPMs do that correctly.
2863 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
2864 through to CGI scripts. PR 9163
2865 [Brian Reid <breid customlogic.com>,
2866 Zvi Har'El <rl math.technion.ac.il>]
2868 *) binbuild.sh: Make sure that we use the expat from our source
2869 tree so that there aren't any surprises on the target machine.
2872 *) mod_cgid: Add retry logic for when the daemon can't fork fast
2873 enough to keep up with new requests. Start using
2874 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
2875 when we can't talk to the daemon. [Jeff Trawick]
2877 *) apxs: LTFLAGS envvar can override default libtool options. Try
2878 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
2879 the covers. [Jeff Trawick]
2881 *) The Location: response header field, used for external
2882 redirect, *must* be an absoluteURI. The Redirect directive
2883 tested for that, but RedirectMatch didn't -- it would allow
2884 almost anything through. Now it will try to turn an abs_path
2885 into an absoluteURI, but it will correctly varf like Redirect
2886 if the final redirection target isn't an absoluteURI. [Ken Coar]
2888 Changes with Apache 2.0.31
2890 *) Create the scoreboard (in the parent) in a global pool context,
2891 so it survives graceful restarts. This fixes a SEGV during
2892 graceful restarts. [Aaron Bannert]
2894 *) Add a timeout option to the proxy code 'ProxyTimeout'
2897 *) FTP directory listings are now always retrieved in ASCII mode.
2898 The FTP proxy properly escapes URI's and HTML in the generated
2899 listing, and escapes the path components when talking to the FTP
2900 server. It is now possible to browse the root directory by using
2901 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
2902 Also, the last path component may contain wildcard characters
2903 '*' and '?', and if they do, a directory listing is created instead
2904 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
2907 *) Added single-listener unserialized accept support to the
2908 worker MPM [Brian Pane]
2910 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
2911 the incoming host header through to the proxied server
2912 [Geoff <g.russell ieee.org>]
2914 *) New Directive Option for ProxyPass. It now can block a location
2915 from being proxied [Jukka Pihl <jukka.pihl entirem.com>]
2917 *) Don't let the default handler try to serve a raw directory. At
2918 best you get gibberish. Much worse things can happen depending
2919 on the OS. [Jeff Trawick]
2921 *) Change the pre_config hook to return a value. Modules can now emit
2922 an error message and then cause the server to quit gracefully during
2923 startup. This required a bump to the MMN. [Aaron Bannert]
2925 *) Fix some unix socket descriptor leaks in the handler side of
2926 mod_cgid (the part that runs in the server process). Whack a
2927 silly "close(-1)" in the handler too. [Jeff Trawick]
2929 *) Change the pre_mpm hook to return a value, so that scoreboard
2930 init errors percolate up to code that knows how to exit
2931 cleanly. This required a bump to the MMN. [Jeff Trawick]
2933 *) Add the socket back to the conn_rec and remove the create_connection
2934 hook. The create_connection hook had a design flaw that did not
2935 allow creating connections based on vhost info. [Bill Stoddard]
2937 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
2938 Resolves the common case of using negotation to resolve the request
2939 /script/foo for /script.cgi/foo. [William Rowe]
2941 *) Added new functions ap_add_(input|output)_filter_handle to
2942 allow modules to bypass the usual filter name lookup when
2943 adding hard-coded filters to a request [Brian Pane]
2945 *) caching should now work on subrequests (still very experimental)
2948 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
2950 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
2953 *) Refactor ap_rgetline so that it does not use an internal brigade.
2954 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
2956 *) Remove mod_auth_db. [Justin Erenkrantz]
2958 *) Do not install unnecessary pcre headers like config.h and internal.h.
2959 [Joe Orton <joe manyfish.co.uk>]
2961 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
2962 (as it does for a normal request). quick_handled sub-requests now work
2963 in mod-include [Ian Holsman]
2965 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
2966 'CONTENT' one, as it needs to run AFTER all content headers
2968 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
2971 *) Split out blocking from the mode in the input filters.
2974 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
2976 *) Cause Win32 to capture all child-worker process errors in
2977 Apache to the main server error log, until the child can
2978 open its own error logs. [William Rowe]
2980 *) HPUX 11.*: Do not kill the child process when accept()
2981 returns ENOBUFS on HPUX 11.*. (ported from th 1.3 patch)
2982 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>, Bill Stoddard]
2984 *) Fix a problem in the parsing of the <Proxy foo> directive.
2987 *) rewrite of mod_ssl input filter for better performance and less
2988 memory usage [Doug MacEachern]
2990 *) allow quick_handler to be run on subrequests. [Ian Holsman]
2992 *) mod_dav now asks its provider to place content directly into the
2993 filter stack when handling a GET request. The mod_dav/provider
2994 API has changed, so providers need to be updated. [Greg Stein]
2996 *) Clear the output socket descriptor in unixd_accept() to make sure
2997 we don't supply a bogus socket to the caller if the accept fails.
2998 This caused problems with the worker MPM, which tried to process
2999 the returned socket if it was non-NULL. [Brian Pane]
3001 *) Move a check for an empty brigade to the start of core input filter
3002 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
3004 *) Add FileETag directive to allow configurable control of what
3005 data are used to form ETag values for file-based URIs. MMN
3006 bumped to 20020111 because of fields added to the end of
3007 the core_dir_config structure. [Ken Coar]
3009 *) Fix a segfault in mod_rewrite's logging code caused by passing the
3010 wrong config to ap_get_remote_host(). [Jeff Trawick]
3012 *) Allow mod_cgid to work from a binary distribution install by
3013 using 755 for the permissions on the log directory instead of
3016 *) Fixed a segfault that happened during graceful shutdown (or when
3017 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
3019 *) Split all Win32 modules [excluding the core components mod_core,
3020 mod_so, mod_win32 and the winnt mpm] into individual loadable
3021 modules, so the administrator may individually disable the former
3022 compiled-in modules by simply commenting out their LoadModule
3023 directives. [William Rowe]
3025 *) Saved Win32 module authors and porters many future headaches, by
3026 duplicating the appropriate .h files such as os.h into the include
3027 directory, including in the build tree. [William Rowe]
3029 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
3030 Use SSL functions/macros instead of directly dereferencing SSL
3031 structures wherever possible.
3032 Add type-casts for the cases where functions return a generic pointer.
3033 Add $SSL/include to configure search path.
3034 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
3036 *) Moved several pointers out of the shared Scoreboard so it is
3037 more portable, and will present the vhost name across server
3038 generation restarts. [William Rowe]
3040 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
3043 Changes with Apache 2.0.30
3045 *) Fix the main bug for FreeBSD and threaded MPM's. There are
3046 still issues (see STATUS) but at least the server will now
3047 run without crashing the machine.
3048 [David Reid, Aaron Bannert, Justin Erenkrantz]
3050 *) Fix a typo in mod_deflate's m4 config section.
3051 [albert chin <china thewrittenword.com>]
3053 *) Fix a couple of mod_proxy problems forwarding HTTP connections
3054 and handling CONNECT:
3055 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
3056 (2) Proxy failed to connect when the first IP address returned by
3057 the resolver was unreachable but a secondary IP address was.
3060 *) Fix the module identifer as shown in the docs for various core
3061 modules (e.g., the identifer for mod_log_config was previously
3062 listed as config_log_module). PR #9338
3063 [James Watson <ap2bug sowega.org>]
3065 *) Fix LimitRequestBody directive by placing it in the HTTP
3066 filter. [Justin Erenkrantz]
3068 *) Fix mod_proxy seg fault when the proxied server returns
3069 an HTTP/0.9 response or a bogus status line.
3072 *) Prevent mod_proxy from truncating one character off the
3073 end of the status line returned from the proxied server.
3074 [Adam Sussman, Bill Stoddard]
3076 *) Eliminate loop in ap_proxy_string_read().
3077 [Adam Sussman, Bill Stoddard]
3079 *) Provide $0..$9 results from mod_include regex parsing.
3082 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
3084 *) Introduced the ForceLanguagePriority directive, to prevent
3085 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
3086 when using Multiviews. [William Rowe]
3088 *) Fix a problem which prevented mod_cgid and suexec from working
3089 together reliably [Greg Ames]
3091 *) Remove the call to exit() from within mod_auth_digest's post_config
3092 phase. [Aaron Bannert]
3094 *) Fix a problem in mod_auth_digest that could potentially cause
3095 problems with initialized static data on a system that uses DSOs.
3098 *) Fix a segfault in the worker MPM that could happen during
3099 child process exits. [Brian Pane, Aaron Bannert]
3101 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
3103 *) Fix matching of vhosts by ip address so we find IPv4
3104 vhost address when target address is v4-mapped form of
3105 that address. [Jeff Trawick]
3107 *) More performance tweaks to the BNDM string-search algorithm
3108 used to find "<!--#" tokens in mod_include [Brian Pane]
3110 *) Miscellaneous small performance fixes: optimized away various
3111 string copy operations and removed large temp buffers from
3112 the stack [Brian Pane]
3114 *) Fixed startup segfault that occurred when a VirtualHost
3115 directive had a port but no address [Brian Pane]
3117 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
3119 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
3120 if oslevel < WINNT. This should fix several problems reported
3121 Against 2.0.28 on Windows 98 [Bill Stoddard]
3123 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
3124 to fail. [Bill Stoddard]
3126 *) Change core code to allow an MPM to set hard thread/server
3127 limits at startup. prefork, worker, and perchild MPMs now have
3128 directives to set these limits. [Jeff Trawick]
3130 *) Win32: The async AcceptEx() event should be autoreset upon
3131 successful completion of a wait (WaitForSingleObject). This
3132 eliminates a number of spurious
3133 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
3136 *) Move any load library path environment variables out of
3137 apachectl and into a separate environment variable file which
3138 can be more easily tailored by the admin. The environment
3139 variable file as built by Apache may have additional system-
3140 specific settings. For example, on OS/390 we tailor the heap
3141 settings to allow lots of threads. [Jeff Trawick]
3143 *) Use the new APR pool code to reduce pool-related lock
3144 contention in the worker MPM. [Sander Striker]
3146 *) The POD no longer assumes the child is listening on 127.0.0.1
3147 and now pulls the first hostname in the list of listeners to
3148 perform the dummy connect on. This fixes a bug when the user
3149 had configured the Listen directive for an IP other than
3150 127.0.0.1. This would result in undead children and error
3151 messages such as "Connection refused: connect to listener".
3154 *) The worker MPM now respects the LockFile setting, needed to
3155 avoid locking problems with NFS. [Jeff Trawick]
3157 *) Fix segfault when worker MPM receives SIGHUP.
3158 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
3160 *) Fix bug that could potentially prevent the perchild MPM from
3161 working with more than one vhost/uid. [Aaron Bannert]
3163 *) Change make install and apxs -i processing of DSO modules to
3164 perform special handling on platforms where libtool doesn't install
3165 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
3166 which prevented standard LoadModule statements from working.
3169 *) Whenever mod_so is enabled (not just when there are DSOs for
3170 our modules), do whatever special magic is required for compiling/
3171 loading third-party modules. This allows third-party DSOs to
3172 be used on an AIX build when there were no built-in modules
3173 built as DSOs. (This should help on OS/390 and BeOS as well.)
3176 *) Allow apxs to be used to build DSOs on AIX without requiring the
3177 user to hard-code the list of import files. (This should help
3178 on OS/390 and BeOS as well.) [Jeff Trawick]
3180 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
3181 PR 8563, 8919 [William Rowe]
3183 *) Get binary builds working when libapr and libaprutil are built
3186 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
3187 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar pacbell.net>,
3188 Gary Hook <ghook us.ibm.com>, Victor Orlikowski, Jeff Trawick]
3190 *) Fix the handling of SSI directives in which the ">" of the
3191 terminating "-->" is the last byte in a file [Brian Pane]
3193 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
3194 message that we had back in apache-1.3 and still have scattered
3195 throughout our docs. [Aaron Bannert]
3197 *) Prevent the Win32 port from continuing after encountering an
3198 error in the command line args to apache. [William Rowe]
3200 *) On a error in the proxy, make it write a line to the error log
3203 *) Various mod_ssl performance improvements [Doug MacEachern]
3205 Changes with Apache 2.0.29
3207 *) Add buffering in core_output_filter to ensure that long
3208 lists of small buckets don't cause small packet writes.
3209 [Brian Pane, Ryan Bloom]
3211 *) Fix the installation target to make sure that the manual is
3212 installed in the correct location.
3213 [Yoshifumi Hiramatsu <hiramatu boreas.dti.ne.jp> and
3214 Gomez Henri <hgomez slib.fr>]
3216 *) Fix the cmd command for mod_include. When we are processing
3217 a cmd command, we do not want to use the r->filename to set
3218 the command name. The command comes from the SSI tag. To do this,
3219 I added a variable to the function that builds the command line
3220 in mod_cgi. This allows the include_cmd function to specify
3221 the command line itself. [Ryan Bloom]
3223 *) Change open_logs hook to return a value, allowing you
3224 to flag a error while opening logs
3225 [Ian Holsman, Doug MacEachern]
3227 *) Change post_config hook to return a value, allowing you
3228 to flag a error post config
3229 [Ian Holsman, Jeff Trawick]
3231 *) Allow SUEXEC_BIN (the path to the suexec binary that is
3232 hard-coded into the server) to be specified to the configure
3233 script by the --with-suexec-bin parameter. [Aaron Bannert]
3235 *) Fix segv in worker MPM following accept on pipe-of-death
3238 *) Add mod_deflate to experimental.
3239 [Ian Holsman, Justin Erenkrantz]
3241 *) Bail out at configure time if an invalid MPM was specified.
3242 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
3244 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
3245 configured [John Sterling <sterling covalent.net>]
3247 *) Fix apxs to use sbindir. [Henri Gomez <hgomez slib.fr>]
3249 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
3251 *) Optimization for the BNDM string-search function in
3252 mod_include. [Brian Pane]
3254 *) Fixed the behavior of the XBitHack directive.
3255 [Taketo Kabe <kabe sra-tohoku.co.jp>, Cliff Woolley] PR#8804
3257 *) The threaded MPM for Unix has been removed. Use the worker
3258 MPM instead. [various]
3260 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
3261 in logging the error from a failed DNS lookup. [Jeff Trawick]
3263 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
3266 *) Get mod_cgid killed when a MPM exits due to a fatal error.
3269 *) Fix a file descriptor leak in mod_include. When we include a
3270 file, we use a sub-request, but we didn't destroy the sub-request
3271 immediately, instead we waited until the original request was
3272 done. This patch closes the sub-request as soon as the data is
3273 done being generated. [Brian Pane <bpane pacbell.net>]
3275 *) Allow modules that add sockets to the ap_listeners list to
3276 define the function that should be used to accept on that
3277 socket. Each MPM can define their own function to use for
3278 the accept function with the MPM_ACCEPT_FUNC macro. This
3279 also abstracts out all of the Unix accept error handling
3280 logic, which has become out of synch across Unix MPMs.
3283 *) Fix a bug which would cause the response headers to be omitted
3284 when sending a negotiated ErrorDocument because the required
3285 filters were attached to the wrong request_rec.
3286 [John Sterling <sterling covalent.net>]
3288 *) Remove commas from the end of the macros that define
3289 directives that are used by MPMs. Prior to this patch,
3290 you would use these macros without commas, which was unlike
3291 the macros for any other directives. Now, the caller provides
3292 the comma rather than the macro providing it. This makes
3293 the macros look more like the rest of the directives.
3294 [Ryan Bloom and Cliff Woolley]
3296 *) Add 'redirect-carefully' environment option to disable sending
3297 redirects under special circumstances. This is helpful for
3298 Microsoft's WebFolders when accessing a directory resource via
3299 DAV methods. [Justin Erenkrantz]
3301 *) Begin to abstract out the underlying transport layer.
3302 The first step is to remove the socket from the conn_rec,
3303 the server now lives in a context that is passed to the
3304 core's input and output filters. This forces us to be very
3305 careful when adding calls that use the socket directly,
3306 because the socket isn't available in most locations.
3309 *) Really reset the MaxClients value in worker and threaded
3310 when the configured value is not a multiple of the number
3311 of threads per child. We said we did previously but we
3312 forgot to. [Jeff Trawick]
3314 *) Add Debian layout. [Daniel Stone <daniel sfarc.net>]
3316 *) If shared modules are requested and mod_so is not available,
3317 produce a fatal config-time error. [Justin Erenkrantz]
3319 *) Improve http2env's performance by cutting the work it has to
3320 do. [Brian Pane <bpane pacbell.net>]
3322 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
3323 [Brian Pane <bpane pacbell.net>]
3325 Changes with Apache 2.0.28
3327 *) Fix infinite loop in mod_cgid.c.
3328 [Dale Ghent <daleg elemental.org>, Brian Pane <bpane pacbell.net>]
3330 *) When no port is given in a "ServerName host" directive, the
3331 server_rec->port is now set to zero, not 80. That allows for
3332 run-time deduction of the correct server port (depending on
3333 SSL/plain, and depending also on the current setting of
3334 UseCanonicalName). This change makes redirections
3335 work, even with https:// connections. As in Apache-1.3, the
3336 connection's actual port number is never used, only the ServerName
3337 setting or the client's Host: setting. Documentation updated
3338 to reflect the change. [Martin Kraemer]
3340 *) Add a '%{note-name}e' argument to mod-headers, which works in
3341 the same way as mod_log_confg. [Ian Holsman]
3343 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
3344 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
3345 MPMs. [Cliff Woolley]
3347 *) Introduce htdbm, a user management utility for db/dbm authorization
3348 databases. [Mladen Turk <mturk mappingsoft.com>]
3350 *) Optimize usage of strlen and strcat in ap_directory_walk.
3351 [Brian Pane <bpane pacbell.net>]
3353 Changes with Apache 2.0.27
3355 *) Introduce an Apache mod_ssl initial configuration template
3356 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
3358 *) Fixed a memory leak in the getline parsing code that could
3359 be triggered by arbitrarily large header lines. Requests
3360 from the core input filter for single lines are now limited
3361 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
3363 *) Fix a truncation bug in how we print the port on the Via: header.
3364 The routine that prints the Via: header now takes a length for
3365 the port string. [Zvi Har'El <rl math.technion.ac.il>]
3367 *) Some syntax errors in mod_mime_magic's magic file can result
3368 in a 500 error, which previously was unlogged. Now we log the
3369 error. [Jeff Trawick]
3371 *) Add the support/checkgid helper app, which checks the run-time
3372 validity of group identifiers usable in the Group directive.
3375 *) Various --enable-so options have been fixed: --enable-so is
3376 treated as "static"; explicit --enable-so=shared issues an error;
3377 and explicit --enable-so fails with error on systems without
3378 APR_HAS_DSO. [Aaron Bannert]
3380 *) Fix a segfault in the core input filter when the client socket
3381 gets disconnected unexpectedly. [Cliff Woolley]
3383 *) Fix the reporting for child processes that die. This removes
3384 all of the non-portable W* macros from Apache.
3385 [Jeff Trawick and Ryan Bloom]
3387 *) Win32: Track and display "Parent Server Generation:" in
3388 mod_status output. The generation will be bumped at
3389 server graceful restart, when the child process exits
3390 by hitting MaxRequestsPerChild or if the child
3391 process exits abnormally. [Bill Stoddard]
3393 *) Win32: Fix problem where MaxRequestsPerChild directive was
3394 not being picked up in favor of the default. Enable
3395 the parent to start up a new child process immediately upon
3396 the old child starting shutdown.
3399 *) Fix some bungling of the remote port in rfc1413.c so that
3400 IdentityCheck retrieves the proper user id instead of failing
3401 and thus always returning "nobody."
3402 [Dick Streefland <Dick.Streefland xs4all.nl>]
3404 *) Introduced thread saftey for mod_rewrite's internal cache.
3405 [Brian Pane <bpane pacbell.net>]
3407 *) Simplified mod_env's directives to behave as most directives are
3408 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
3409 directive following that UnsetEnv within the same container.
3410 Also provides a runtime startup warning if a PassEnv configured
3411 environment value is undefined. [William Rowe]
3413 *) The worker MPM is now completely ported to APR's new lock API. It
3414 uses native APR types for thread mutexes, cross-process mutexes,
3415 and condition variables. [Aaron Bannert]
3417 *) Sync up documentation to remove all references to the now deprecated
3418 Port directive. [Justin Erenkrantz]
3420 *) Moved all ldap modules from the core to httpd-ldap sub-project
3423 *) Exit when we can't listen on any of the configured ports. This
3424 is the same behavior as 1.3, and it avoids having the MPMs to
3425 deal with bogus ap_listen_rec structures. [Jeff Trawick]
3427 *) Cleanup the proxy code that creates a request to the origin
3428 server. This change adds an optional hook, which allows modules
3429 to gain control while the request is created if the proxy module
3430 is loaded. The purpose of this hook is to allow modules to add
3431 input and/or output filters to the request to the origin. While
3432 I was at it, I made the core use this hook, so that proxy request
3433 creation uses some of the code from the core. This can still be
3434 greatly improved, but this is a good start. [Ryan Bloom]
3436 Changes with Apache 2.0.26
3438 *) Port the MaxClients changes from the worker MPM to the threaded
3441 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
3442 with the new input filtering system. [Justin Erenkrantz]
3444 *) Introduce the MultiviewsMatch directive, to allow the operator
3445 to be flexible in recognizing Handlers and Filters filename
3446 extensions as part of the Multiviews matching logic, strict with
3447 MultiviewsMatch NegotiatedOnly to accept only filename extentions
3448 that designate negotiated parameters, (content type, charset, etc.)
3449 or MultiviewsAll for the 1.3 behavior of matching any files, even
3450 if they have unregistered extensions. [William Rowe]
3452 *) Fixed the configure script to add a LoadModule directive to
3453 the default httpd.conf for any module that was compiled
3454 as a DSO. [Aaron Bannert <aaron clove.org>]
3456 *) rewrite mod_ssl input filtering to work with the new input filtering
3457 system. [Justin Erenkrantz]
3459 *) prefork: Don't segfault when we are able to listen on some but
3460 not all of the configured ports. [Jeff Trawick]
3462 *) Build mod_so even if no core modules are built shared.
3463 [Aaron Bannert <aaron clove.org>]
3465 *) Introduce ap_directory_walk rewrite (with further optimizations
3466 required) to adapt to the ap_process_request_internal() changes.
3467 Optimized so subrequests and redirects now reuse previous section
3468 merges, until we mismatch with the original directory_walk, and
3469 precomputed r->finfo results will cause directory_walk to skip
3470 the most expensive phases of the function. [William Rowe]
3472 *) Allow ApacheMonitor to connect to and control Apache on other
3473 WinNT/2K machines. [Mladen Turk <mturk mappingsoft.com>]
3475 *) Remove the Port directive. In it's place, the Listen directive
3476 is now a required directive, which tells Apache what port to
3477 listen on. The ServerName directive has also been extended
3478 to accept an optional port. If the port is specified to the
3479 ServerName, the server will report that port whenever it
3480 reports the port that it is listening on. This change was
3481 made to ease configuration errors that stem from having a Port
3482 directive, and a Listen directive. In that situation, the server
3483 would only listen to the port specified by the Listen command,
3484 which caused a lot of confusion to users. [Ryan Bloom]
3486 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
3487 build, as loadable modules. [William Rowe]
3489 *) Fix --enable-mods-shared processing. If most is specified,
3490 then all modules that can be compiled as shared modules are.
3491 [Aaron Bannert <aaron clove.org>]
3493 *) Update the mime.types file to map video/vnd.mpegurl to mxu
3494 and add commonly used audio/x-mpegurl for m3u extensions.
3495 [Heiko Recktenwald <uzs106 uni-bonn.de>, Lars Eilebrecht]
3497 *) Eliminate the depreciated r->content_language, in favor of the array
3498 r->content_languages introduced many years ago. Module authors must
3499 substantially overhaul their modules, so this needs to be upgraded
3500 if the module still relied on backwards-brokeness. [William Rowe]
3502 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
3505 *) Rewrite the input filtering mechanisms to consolidate and reorganize
3506 code. In short, core_input_filter does something now and
3507 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
3509 *) Update the Win32 build to re-absorb mod_proxy and family.
3512 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
3513 current SDK.) [William Rowe]
3515 *) Some style changes to the code that does ProxyErrorOverride. Fixed
3516 config merge behaviour. [Graham Leggett]
3518 *) Allow support programs to be compiled against a static version
3519 of libapr. This allows the smaller support programs to be
3520 relocated. [Aaron Bannert <aaron clove.org>]
3522 *) Update the mime.types file to the registered media types as
3523 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
3525 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
3526 number of clients that can connect at the same time, instead of
3527 specifying the maximum number of child processes.
3528 [Aaron Bannert <aaron clove.org>]
3530 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
3531 be consistent with 1.3. [Justin Erenkrantz]
3533 *) Cache apr_explode_localtime() value for 15 seconds.
3534 [Brian Pane <bpane pacbell.net>]
3536 *) Fix mod_include to not return ETag or Last-Modified headers.
3537 [Ian Holsman <ianh cnet.com>]
3539 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron clove.org>]
3541 *) Eliminate the wasteful run-time conversion of method names from strings
3542 to numbers in places where the methods are known at compile time.
3543 [Brian Pane <bpane pacbell.net>]
3545 *) Turn the worker MPM's queue into a LIFO. This may
3546 improve cache-hit performance under some conditions.
3547 [Aaron Bannert <aaron clove.org>]
3549 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
3550 support it. [Justin Erenkrantz]
3552 *) Cleanup the worker MPM. We no longer re-use transaction
3553 pools. This incurs less overhead than shuffling the pools
3554 around so that they can be re-used. Remove one of the
3555 queue's condition variables. We just redefined the API to
3556 state that you can't try to add more stuff than you allocated
3557 segments for. [Aaron Bannert <aaron clove.org>]
3559 *) Fix SSL VPATH builds [Cody Sherr <csherr covalent.net>]
3561 *) Fixed persistent connections when a request contains a body.
3564 *) mod_dav uses a new API to speak to the backend provider for dead
3565 property management. [Greg Stein]
3567 *) Remove the Win32 script-processing exception from mod_cgi, and
3568 roll build_command_line/build_argv_list into a unified, overrideable
3569 ap_cgi_build_command optional function. [William Rowe]
3571 *) Rewrite find_start_sequence to use a better search algorithm
3572 to find the start tag. [Justin Erenkrantz]
3574 *) Fix a seg fault in mod_include. When we are generating an
3575 internal redirect, we must set r->uri to "", not a bogus
3576 string, and not NULL. [Ryan Bloom]
3578 *) Optimized location_walk, so subrequests, redirects and second passes
3579 now reuse previous section merges on a <Location > by <Location >
3580 basis, until we mismatch with the original location_walk.
3583 *) Back out the 1.45 change to util_script.c. This change made
3584 us set the environment variable REQUEST_URI to the redirected
3585 URI, instead of the originally requested URI.
3586 [Taketo Kabe <kabe sra-tohoku.co.jp>]
3588 *) Make mod_include do lazy evaluation of potentially expensive to
3589 compute variables. [Brian Pane <bpane pacbell.net>]
3591 *) Fix logging of bytes sent for HEAD requests. %b and %B should
3592 log either - or 0, before this patch, they were both logging
3593 the file size. [Taketo Kabe <kabe sra-tohoku.co.jp>]
3595 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
3596 than per character. [Brian Pane <bpane pacbell.net>]
3598 *) Normalize the primary request, redirects and sub-requests to
3599 run the same ap_process_request_internal for consistency in
3600 robustness, behavior and security. [William Rowe]
3602 *) Fix a segfault with mod_include when r->path_info is not set
3603 (which is the case with mod_proxy). [Ian Holsman <ianh cnet.com>]
3605 *) Add -X functionality back. This indicates to all MPMs and any other
3606 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
3608 *) Some initial support for the cygwin platform [prefork only].
3609 This is not to be confused with support for the WinNT/Win32
3610 platform, which is the recommended configuration for native
3611 Win32 users. The cygwin platform support is recommended for
3612 cygwin platform users. [Stipe Tolj <tolj wapme-systems.de>]
3614 *) Changed syntax of Set{Input|Output}Filter. The list of filters
3615 must be semicolon delimited (if more than one filter is given.)
3616 The Set{Input|Output}Filter directive now overrides a parent
3617 container's directive (e.g. SetInputFilter in <Directory /web/foo>
3618 will override any SetInputFilter directive in <Directory /web>.)
3619 This new syntax is more consistent with Add{Input|Output}Filter
3620 directives defined in mod_mime. Also cures a bug in prior releases
3621 where the Set{Input|Output}Filter directive would corrupt the
3622 global configuration if the multiple directives were nested.
3625 *) Cured what's ailed mime for quite some time. If an AddSomething
3626 was given in the configuration (Language, Charset, Handler or
3627 Encoding) Apache would set the content type as given by AddType,
3628 but refused to check the mime.types file if AddType wasn't given
3629 for that specific extension. Setting the AddHandler for .html
3630 without setting the AddType text/html html would cause Apache to
3631 use the default content type. [William Rowe]
3633 *) Added some bulletproofing to memory allocation in the LDAP cache
3634 code. [Graham Leggett]
3636 Changes with Apache 2.0.25
3638 *) Move the installed /manual directory out of the /htdocs/ tree, so
3639 that it can be kept more independently from the remaining document
3640 root. The "Alias /manual ..." already allowed for easy projection
3641 into existing private document trees. [Martin Kraemer]
3643 *) Add specified user attributes to the environment when using
3644 mod_auth_ldap. This allows you to use mod_include to embed specified
3645 user attributes in a page like so:
3646 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
3649 *) Fix a performance problem with the worker MPM. We now create
3650 transaction pools once, and re-use them for each connection.
3651 [Aaron Bannert <aaron clove.org>]
3653 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
3654 of a 'handler' or 'filter', so that any filename extension that does
3655 not contribute to the negotiated metadata can't be served without
3656 an explicit request. E.g., if the .Z extension is associated with
3657 an unzip filter, the user request somefile.Z.html, mod_negotiation
3658 won't serve it. It can serve somefile.Z.html when somefile.Z is
3659 requested, since the .Z extension is explictly requested, if the
3660 .html extension is associated with ContentType text/html.
3663 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
3664 and corresponding AddOutputFilter syntax, to insert one or more
3665 filters by mod_mime filename extension processing.
3668 *) Fix a growing connection pool in core_output_filter() for
3669 keepalive requests. [Jeff Trawick]
3671 *) Moved split_and_pass_pretag_buckets back to being a
3672 macro at Ryans's request. Removed the return from it
3673 by setting and returning a return code instead. Updated
3674 the code to check the return code from the macro and
3675 do the right thing. [Paul J. Reder]
3677 *) Fix a segfault when a numeric value was received for Host:.
3680 *) Add a function ap_remove_input_filter. This is to match
3681 up with ap_remove_output_filter. [Ryan Bloom]
3683 *) Clean up location_walk, so that this step performs a minimum
3684 amount of redundant effort (it must be run twice, but it will no
3685 longer reparse all <Location > blocks when the request uri
3686 hadn't changed.) [William Rowe]
3688 *) Eliminate proxy: (and all other 'special') processing from the
3689 ap_directory_walk() phase. Modules that want to use special
3690 walk logic should refer to the mod_proxy map_to_location example,
3691 with it's proxy_walk and proxysection implementation. This makes
3692 either directory_walk flavor much more legible, since that phase
3693 only runs against real <Directory > blocks.
3696 *) SECURITY: Fix a security problem in mod_include which would allow
3697 an SSI document to be passed to the client unparsed.
3698 [Cliff Woolley, Brian Pane]
3700 *) Introduce the map_to_storage hook, which allows modules to bypass
3701 the directory_walk and file_walk for non-file requests. TRACE
3702 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
3703 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
3706 *) Add the ability for mod_include to add the INCLUDES filter
3707 if the file is configured for the server-parsed handler.
3708 This makes the configuration for .shtml files much easier
3709 to understand, and allows mod_include to honor Apache 1.3
3710 config files. Based on Doug MacEachern's patch to PHP
3711 to do the same thing. [Ryan Bloom]
3713 *) force OpenSSL to ignore process local-caching and to always
3714 get/set/delete sessions using mod_ssl's callbacks
3715 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
3716 Geoff Thorpe <geoff geoffthorpe.net>]
3718 *) Make the worker MPM shutdown and restart cleanly. This also
3719 cleans up some race conditions, and gets the worker using
3720 pools more cleanly. [Aaron Bannert <aaron clove.org>]
3722 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
3724 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
3726 *) Fix for mod_include. Ryan's patch to check error
3727 codes put a return in the wrong place. Also, the
3728 include handler return code wasn't being checked.
3729 I don't like macros with returns, so I converted
3730 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
3731 [Paul J. Reder <rederpj raleigh.ibm.com>]
3733 *) fix segv in mod_mime if no AddTypes are configured
3734 [John Sterling <sterling covalent.net>]
3736 *) Enable ssl client authentication at SSL_accept time
3737 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
3739 *) Fix a segfault in mod_include when the original request has no
3740 associated filename (e.g., we're filtering the error document for
3741 a bad URI). [Jeff Trawick]
3743 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
3745 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
3746 of httpd is started and shuts down due to socket conflict. Moving the
3747 call to ap_log_pid solves the problem.
3749 *) Changed the late-1.3 log_config substitution %c to %X, to log the
3750 status of the closed connection, as it conflicts with the far more
3751 common, historical ssl logging directive %...{var}c. [William Rowe]
3753 *) Added the common error/ tree to the build/install targets
3754 (similar to the common icons/ tree) for the multi-language error
3755 messages that Lars committed earlier. [William Rowe]
3757 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
3759 *) Added a default commented-out mod_ldap and mod_auth_ldap
3760 configuration to httpd-std.conf and httpd-win.conf
3763 *) Added documentation for mod_ldap and mod_auth_ldap.
3766 *) Enabled negative caching on attribute comparisons in the LDAP cache.
3767 Fixed a problem where the default cache TTL was set in milliseconds
3768 not microseconds causing the cache to time out almost immediately.
3771 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
3772 module code to follow APR. [Graham Leggett]
3774 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
3775 cleaned up when the connection pool pool is cleaned up.
3778 *) Fix a minor issue with Jeff Trawick's mod_include
3779 patch. Without this patch, the code will just allocate
3780 more bytes in get_combined_directive than are needed.
3783 *) Added the LDAP authentication module mod_auth_ldap.
3784 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
3786 *) Added the LDAP cache and connection pooling module mod_ldap.
3787 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
3789 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
3790 by allowing a module to disable itself if its prerequisites are not
3791 met. [Justin Erenkrantz]
3793 Changes with Apache 2.0.24
3795 *) Fix a couple of issues in mod_include when the tag appeared at
3796 offsets near 8192 in the file being parsed. [Jeff Trawick]
3798 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
3799 reached. [Jeff Trawick]
3801 *) Numerous improvements to the Win32 build system. Introduced command line
3802 builds without requiring .mak files for MSVC 6.0 and later versions.
3803 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
3806 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
3807 reporting of uninstalled services and other error conditions, and changed the
3808 default service name to Apache2. [William Rowe]
3810 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
3811 compatibility with existing Apache 1.3 Win32 Apache management utilites.
3812 [Mladen Turk <mturk mappingsoft.com>, William Rowe]
3814 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
3815 [William Rowe, Greg Ames]
3817 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
3818 and RemoveCharset directives. [William Rowe]
3820 *) The Unix MPMs other than perchild now allow child server
3821 processes to use the accept mutex when starting as root and
3822 using SysV sems for the accept mutex. Previously, this
3823 combination would lead to fatal errors in the child server
3824 processes. perchild can't use SysV sems because of security
3825 issues. [Jeff Trawick, Greg Ames]
3827 *) Added Win32 revision stamp resources to all http binaries
3828 (including modules/ and support/ tools.) PR7322 [William Rowe]
3830 *) Fix ap_rvprintf to support more than 4K of data at one time.
3831 [Cody Sherr <csherr covalent.net>]
3833 *) We have always used the obsolete/deprecated Netscape syntax
3834 for our tracking cookies; now the CookieStyle directive
3835 allows the Webmaster to choose the Netscape, RFC2109, or
3836 RFC2965 format. The new CookieDomain directive allows the
3837 setting of the cookie's Domain= attribute, too. PR #s 5006,
3838 5023, 5920, 6140 [Ken Coar]
3840 *) Tweak server/Makefile so that the rules for generating exports.c
3841 are compatible with make utilities which don't expand wildcards
3842 in a dependency list (e.g., OS/390 make, certain levels of GNU
3843 make). [Jeff Trawick]
3845 *) Install the SSL headers. [John Sterling <sterling covalent.net>]
3847 *) Begin to sanitize the MPM configuration directives. Now, all
3848 MPMs use the same functions for all common MPM directives. This
3849 should make it easier to catch all bugs in these directives once.
3850 [Cody Sherr <csherr covalent.net>]
3852 *) Close a major resource leak. Every time we had issued a
3853 graceful restart, we leaked a socket descriptor.
3856 *) Fix a problem with the new method code. We need to cast
3857 the 1 to an apr_int64_t or it will be treated as a 32-bit
3858 integer, and it will wrap after being shifted 32 times.
3859 [Cody Sherr <csherr covalent.net> and Ryan Morgan <rmorgan covalent.net>]
3861 *) Fix a bug in mod_expires. Previous to this patch, if you
3862 told mod_expires to add 604800 seconds to the last-modified
3863 time, it actually added 604800 usec's to the last-modified time,
3864 so that when looking at the response it looked like nothing
3865 had been done. The root of the problem was that we always compute
3866 time in usec's, but we ask users to input sec's. This means we
3867 need to convert to usec's before using those values.
3870 *) The worker MPM now handles shutdown and restart requests. It
3871 definitely isn't perfect, but we do stop the servers correctly.
3872 The biggest problem right now is that SIGHUP causes the server to
3873 just die. [Ryan Bloom]
3875 Changes with Apache 2.0.23
3877 *) Use the prefork MPM by default on Unix. [various]
3879 *) Added a systray icon monitor application for Win32.
3880 [Mladen Turk <mturk mappingsoft.com>]
3882 *) mod_rewrite: Fix the line ending on some non-Unix systems for
3883 messages written to the rewrite log.
3884 [Richard Labennett <rlabenn us.ibm.com>]
3886 *) All mod_autoindex query parsing is now quietly quashed with the
3887 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
3888 still drops the column sort <a href>'s for the column headers, but
3889 IgnoreClient is required to ignore these Query options entirely.
3892 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
3893 to allow the client to select plain, FancyIndexing or HTMLTable
3894 formatting, V=[0|1] to inhibit or enable version sorting, and
3895 P=pattern to return only specific files. The old Query Arguments
3896 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
3897 as before), and O=A|D for ordering ascending or descending.
3900 *) Fixed an error in mod_include's directive parsing routines which
3901 caused #if, #elif, and #else expressions containing backslashes
3902 to be improperly evaluated. [Cliff Woolley]
3904 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
3905 drop the icon column, SuppressRules to drop the <hr> elements,
3906 and HTMLTable to create rudimentary HTML table listings (implies
3907 FancyIndexing). [William Rowe]
3909 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
3910 from Apache 1.3.15. This is needed for two reasons, first, given
3911 multiple machines within a server farm, ETags and Last-Modified
3912 stamps won't correspond from machine to machine, and second, many
3913 Unixes don't capture changes to the date or time stamp of existing
3914 files, since these don't modify the dirent itself. [William Rowe]
3916 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
3917 and DirectoryWidth options from Apache 1.3.10.
3918 [William Rowe, Ken Coar]
3920 *) Eliminated FancyIndexing directive, deprecated early in Apache
3921 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
3923 *) mod_autoindex now excludes any file names that would result in
3924 an error, other than a success or redirect. Also optimized
3925 the parent directory, always included except in the URI '/'.
3928 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
3929 negotiated index pages, and prevent the server from defaulting
3930 to an autoindex of the directory. mod_negotiation will now die
3931 with a 500 Internal Error if it could match some filenames
3932 (e.g. for mod_dir) but none can be served. mod_negotation now
3933 refuses to serve any file with an extention that mod_mime doesn't
3934 recognize, and wasn't part of the request. [William Rowe]
3936 *) Eliminate mod_cgi's handling of .exe files without the .exe file
3937 extension. This is already handled by multiviews, if the admin
3938 wishes to AddHandler .exe or define a content type handler and
3939 associate .exe files with that content type. Multiviews must be
3940 enabled to allow these to be served. [William Rowe]
3942 *) Speed up the server's response to a spike in incoming workload
3943 or restarts by assigning empty scoreboard slots to new processes
3944 when they are available. [Greg Ames]
3946 *) Add a handler to mod_includes.c. This handler is designed to
3947 implement the XbitHack directive. This can't be done with a
3948 fixup, because we need to check the content-type, which is
3949 only available in the handler phase. [Ryan Bloom]
3951 *) Make the includes filter check return codes from filters lower in
3952 the filter chain. If a lower level filter returns an error, then
3953 the request needs to stop immediately. This allows mod_include to
3954 stop parsing data once a lower filter recognizes an error.
3957 *) Add the ability to extend the methods that Apache understands
3958 and have those methods <limit>able in the httpd.conf. It uses
3959 the same bit mask/shifted offset as the original HTTP methods
3960 such as M_GET or M_POST, but expands the total bits from an int to
3961 an ap_int64_t to handle more bits for new request methods than
3962 an int provides. [Cody Sherr <csherr covalent.net>]
3964 *) Fix broken mod_mime behavior in merging its arguments. Possible
3965 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
3967 *) Solve many mod_ssl porting issues (too many to detail) with
3968 help from the whole team, but most notably [Ralf S. Engelschall,
3969 Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
3970 Doug MacEachern, William Rowe, Cliff Woolley]
3972 *) More stall fixes for the threaded & worker mpm's.
3973 Make mod_status output more accurate. Don't
3974 count workers in processes which aren't actively
3975 serving requests. [Greg Ames]
3977 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
3979 *) Add a single listener/multiple worker MPM. This MPM is
3980 definately not fully correct, but it allows us to solve many
3981 of the problems that exist in the threaded MPM. This is a
3982 modified version of the threaded MPM. [Ryan Bloom]
3984 *) Improve content generation throughout Apache, providing closer
3985 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
3986 Transitional specifications. [William Rowe]
3988 Changes with Apache 2.0.22
3990 *) Fix a problem where the threaded MPM stalls after restarts or
3991 segfaults. Also prevent multiple active processes from using
3992 the same scoreboard slot. [Greg Ames]
3994 *) Apache/Win32 now fills in the service description with Apache's
3995 server version string, including loaded and advertised modules.
3998 *) Improved support for the Win32 build, to recover gracefully from
3999 missing apr or apr-util directories or the awk interpreter,
4000 create the proper cgi-bin examples, including a test-cgi.bat, and
4001 fix the perl shebang line for printenv.pl, when installing from
4002 the build environment. [William Rowe]
4004 *) Fix a segfault in threaded.c caused by passing uninitialized
4005 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
4007 *) Use new APR number conversion functions to reduce CPU consumption
4008 when setting the content length, and in mod_log_config.
4011 *) Fix problem reported by Taketo Kabe <kabe sra-tohoku.co.jp>
4012 where HEAD response headers were being repeated twice for
4013 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
4014 problem in the http_header filter was exposed by the recent rewrite
4015 of the content_length filter. [Taketo Kabe, Bill Stoddard]
4017 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
4018 restarts. A garbage pointer to a vhost's server_rec from the
4019 previous generation was being left around under certain
4020 conditions. [Greg Ames]
4022 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
4023 used to appear as '(none', without the closing paren.
4024 [Günter Knauf <eflash gmx.net>]
4026 *) Improve the exports generating awk script. In the past, we had
4027 work around problems in the awk script by avoiding some #if and
4028 #ifdefs. This has bitten us many times in generating the exports.c
4029 file. This improvement allows corrects the header file parsing.
4030 [Sander Striker <striker apache.org>]
4032 Changes with Apache 2.0.21
4034 *) Resolve the Win32 htpasswd bug, where a file that existed would be
4035 overwritten, regardless of the -c flag.
4036 [William Rowe, Mladen Turk <mladen.turk mail.inet.hr>]
4038 *) Introduce connection sub-pools into ab. Truncating the lifetime
4039 of these allocations means that ab no longer perpetually grows
4040 its working set, running out of memory on large request attempts.
4043 *) Make scoreboard creation a hook. This allows management
4044 modules to have access to the scoreboard at the time that it is
4045 created, and at every restart request.
4046 [Cody Sherr <csherr covalent.net>]
4048 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
4049 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
4050 daemon index actually used in the scoreboard. I also
4051 updated the pertinent calls. [Paul J. Reder]
4053 *) Win32: Prevent listening sockets from being inherited by
4054 the Apache child process, CGI scripts, rotatelog process
4055 etc. If the Apache child process segfaults, any processes
4056 that the child started are not reaped. Prior to this fix,
4057 these processes inherited the listening sockets which sometimes
4058 prevented the restarted Apache child process from accepting
4059 connections (ie, the server would hang).
4062 *) Provide vhost and request strings when ExtendedStatus is on.
4065 *) Fix some issues with the pod and prefork: check the pod *after*
4066 processing a connection so that a server processing a time-
4067 consuming request bails out as soon as practical; when the
4068 parent process wakes up a server process via connect(), use an
4069 APR timeout on the connect() so that we don't hang for a long
4070 time if there aren't server processes around to do accept().
4071 [Jeff Trawick, Greg Ames]
4073 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
4074 spends a lot of time in apr_table_get calls. Using the default
4075 httpd.conf, the tables for languages and charsets are somewhat
4076 large, so the time spent scanning them on each request is
4077 significant. Replacing the tables with hash tables provides
4078 a nice speedup. [Brian Pane <bpane pacbell.net>]
4080 *) Add two functions to allow modules to access random parts of the
4081 scoreboard. This allows modules compiled for one MPM to access the
4082 scoreboard, even if it the server was compiled for another MPM.
4083 [Harrie Hazewinkel <harrie covalent.net>]
4085 Changes with Apache 2.0.20
4087 *) Fix problem in content-length filter where the filter would
4088 buffer all the output from a CGI before sending any bytes
4089 down the filter stack to the network. This problem would cause
4090 significant memory consumption if the CGIs generated
4091 lots of bytes. [Bill Stoddard]
4093 *) Get non-blocking CGI pipe reads working with the bucket brigades.
4096 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
4099 *) Fix a bug in the threaded MPM that would cause it to kill off all
4100 workers immediately after starting if the number of workers started
4101 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
4103 Changes with Apache 2.0.19
4105 *) Fix problem with threaded MPM. The problem was that if each child
4106 process was busy serving a single long-lived request and the server
4107 was sent a graceful restart signal, the server would stop serving
4108 requests. This would happen because each child process would wait to
4109 die until the last thread was done, and the parent wouldn't spawn any
4110 new children until a process died. Now, the parent looks at the fact
4111 that the children are dying gracefully, and starts new children.
4112 Those new children only start enough threads to compliment the number
4113 of threads in the other child process that shares the same spot in
4114 the scoreboard. In this way, we make sure to never go over
4115 MaxClients. [Ryan Bloom]
4117 *) modified mod_negotiation and mod_autoindex to speed up by almost a
4118 factor of two on apr_dir_read()-enhanced platforms, such as Win32
4119 and OS2, by calling ap_sub_request_lookup_dirent() with the results
4120 already provided by apr_dir_read(). [William Rowe]
4122 *) mod_file_cache is now more robust to filtering and serves requests
4123 slightly more efficiently. [Cliff Woolley]
4125 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
4126 Module was calling ap_rwrite() followed by ap_rflush() but the
4127 served content was not being displayed in the browser. Inspection
4128 of the output stream revealed that the first data chunk was
4129 missing the trailing CRLF required by the RFC. [Bill Stoddard]
4131 *) apxs no longer generates ap_send_http_header() in the example handler
4133 *) Fix an ab problem which could cause a divide-by-zero exception
4134 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
4135 [Ian Holsman <ianh cnet.com>]
4137 *) Solve case-insensitive platforms' confusion about negotiated
4138 filenames, allowing files of differnt case to match in choosing
4139 the document to serve. [William Rowe]
4141 *) Fix brokenness when ThreadsPerChild is higher than the built-in
4142 limit. We left ap_threads_per_child at the higher value which
4143 led to segfaults when doing certain scoreboard operations.
4146 *) Fix seg faults and/or missing output from mod_include. The
4147 default_handler was using the subrequest pool for files and
4148 MMAPs, even though the associated APR structures typically
4149 live longer than the subrequest. [Greg Ames]
4151 *) Extend mod_setenvif to support specifying regular expressions
4152 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
4153 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
4154 will cause HAVE_TS to be set if any of the request headers begins
4155 with "TS" and has a value that begins with any character in the
4156 set [a-z]. [Bill Stoddard]
4158 *) httpd children now re-bind themselves to a random CPU on
4159 multiprocessor systems on AIX via bindprocessor() in 2.0.
4160 [Victor J. Orlikowski]
4162 *) Fix htdigest. It would go into a loop in getline when adding
4163 a second user. [Bill Stoddard]
4165 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
4167 *) Automatically generate httpd.exp for AIX.
4168 DSOs now work again on AIX in 2.0
4169 [Victor J. Orlikowski]
4171 *) Add a new request hook, error_log. This phase allows modules
4172 to act on the error log string _after_ it has been written
4173 to the error log. The goal for this hook is to allow monitoring
4174 modules to send the error string to the monitoring agent.
4177 *) Modify mod_echo to make it use filters for input and output.
4178 [Ryan Morgan <rmorgan covalent.net>]
4180 *) Extend mod_headers to support conditional driven Header
4181 add, append and set. Use SetEnvIf to set an envar and conditionally
4182 add/append/set headers based on this envar thusly:
4184 SetEnvIf TSMyHeader value HAVE_TSMyHeader
4185 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
4187 If the request contains header "TSMyHeader: value" then header
4188 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
4191 *) Extend mod_headers to support using format specifiers on Header
4192 add, append and set header values. Two format specifiers are supported:
4194 %t - reports, in UTC microseconds since the epoch, when the
4195 request was received.
4197 %D - reports the time, in microseconds, between when the request was
4198 received and the response sent.
4201 Header add MyHeader "This request served in %D microseconds. %t"
4203 results in a header being added to the response that looks like this:
4205 MyHeader: This request served in D=5438 microseconds. t=991424704447256
4209 *) Fix reset_filter(). We need to be careful how we remove filters.
4210 If we set r->output_filters to NULL, we also have to reset the
4211 connection's filters. [John Sterling]
4213 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
4215 *) Add a check to ap_die() to make sure the filter stack is sane and
4216 contains the correct basic filters when an error occurs. This fixes
4217 a problem where headers are not being sent on error. [John Sterling]
4219 *) New Header directive 'echo' option. "Header echo regex" will
4220 cause any headers received on the request that match regex to be
4221 echoed to (included in) the response headers.
4224 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
4225 This prevented the inclusion of apr_compat.h. PR #7773
4226 [Oleg Broytmann <phd phd.pp.ru>]
4228 *) Moved util_uri to the apr-util library. This required a bunch of
4229 apr_name changes for the uri utility functions. [Justin Erenkrantz]
4231 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
4232 insert_filter phase so that other filters are not bypassed by default.
4235 *) Reimplement mod_headers as an output filter. mod_headers can now
4236 add custom headers to inbound requests using the RequestHeader directive
4237 and to responses using the same old Header directive. [Graham Leggett]
4239 Changes with Apache 2.0.18
4241 *) Fix command-line processing so that if a bad argument is specified
4242 Apache will exit. [Jeff Trawick]
4244 *) Change the make targets and rules to be consistent in all of the
4245 Apache-owned source trees. [Roy Fielding]
4247 *) Fix processing of the TRACE method. Previously we passed bogus
4248 parms to form_header_field() and it overlaid some vhost structures,
4249 resulting in a segfault in check_hostalias().
4250 [Greg Ames, Jeff Trawick]
4252 *) Win32: Add support for reliable piped logs. If the logging process
4253 goes down, Apache will automatically restart it. This function has
4254 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
4257 *) Do not start piped log processes during the config file
4258 preflight. This change also circumvents a problem on
4259 Windows where the rotatelog processes created during preflight
4260 was not getting cleaned up properly.
4263 *) add "Request Phase Participation" info to mod_info
4266 *) Make first phase changes to the scoreboard data structures in
4267 preparation for the rewriting of the scoreboard per my posted
4268 design notes. [Paul J. Reder]
4270 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
4271 and apr-util, allow it to be overridden by the configure command-line
4272 (default="--silent") and introduce LT_LDFLAGS to replace what we were
4273 formerly abusing as LTFLAGS. [Roy Fielding]
4275 *) Clean up the reporting of incorrect closing container tags.
4276 [Barrie Slaymaker <barries slaysys.com>]
4278 *) Simplify the configure process by moving all libtool stuff to APR
4279 and moving hints.m4 inline. [Roy Fielding]
4281 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
4282 of functions used by mod_proxy for export in the DLL
4283 [Ian Holsman <IanH cnet.com>]
4285 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
4286 request body from its stdin but no reqest body is being written to
4287 the cgi. [Jeff Trawick]
4289 *) mod_log_config: %c connection status incorrectly logged
4290 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
4293 *) Get mod_cern_meta working under Windows
4296 *) Create Files, and thus MMAPs, out of the request pool, not the
4297 connection pool. This solves a small resource leak that had us
4298 not closing files until a connection was closed. In order to do
4299 this, at the end of the core_output_filter, we loop through the
4300 brigade and convert any data we have into a single HEAP bucket
4301 that we know will survive clearing the request_rec.
4302 [Ryan Bloom, Justin Erenkrantz <jerenkrantz ebuilt.com>,
4305 *) Completely revamp configure so that it preserves the standard make
4306 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
4307 the configure additions to EXTRA_* variables. Also, allow the user
4308 to specify NOTEST_* values for all of the above, which eliminates the
4309 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
4310 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
4311 avoid pointless duplications. Fix the order in which flags are given
4312 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
4313 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
4314 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
4315 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
4317 *) Get mod_tls to compile/work better on Windows. PR #7612
4318 [Bernhard Schrenk <b.schrenk improx.com>]
4320 *) Fix shutdown/restart hangs in the threaded MPM.
4321 [Jeff Trawick, Greg Ames, Ryan Bloom]
4323 *) Removed the keptalive boolean from conn_rec because it is now only
4324 used by a single routine and can be replaced by a local variable.
4325 [Greg Stein, Ryan Bloom, Roy Fielding]
4327 *) Patch prefork to put enough of the signal processing back in so that
4328 signals are all handled properly now. The previous patch fixed the
4329 deadlock race condition, but broke the user directed signal handling.
4330 This fixes it to work the way it did before my previous prefork patch
4331 (primarily, SIGTERM is now working).
4333 *) Change how input filters decide how much data is returned to the
4334 higher filter. We used to use a field in the conn_rec, with this
4335 change, we use an argument to ap_get_brigade to determine how much
4336 data is retrieved. [Ryan Bloom]
4338 *) Fix seg fault at start-up introduced by Ryan's change to enable
4339 modules to specify their own logging tags. mod_log_config
4340 registers an optional function, ap_register_log_handler().
4341 ap_register_log_handler() was being called by http_core before
4342 the directive hash table was created. This patch creates the
4343 directive hash table before ap_register_log_handler() is
4344 registered as an optional function.
4345 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
4347 *) Add ap_set_int_slot() function
4348 [John K. Sterling <sterling covalent.net>]
4350 *) Under certain circumstances, Apache did not supply the
4351 right response headers when requiring authentication.
4352 [Gertjan van Wingerde <Gertjan.van.Wingerde cmg.nl>] PR#7114
4353 (This is a port of the change that went into Apache 1.3.19.)
4355 *) Allow modules to specify their own logging tags. This basically
4356 allows a module to tell mod_log_config that when %x is encountered
4357 a specific function should be called. Currently, x can be any single
4358 character. It may be more useful to make this a string at some point.
4361 Changes with Apache 2.0.17
4363 *) If a higher-level filter handles the byterange aspects of a
4364 request, then the byterange filter should not try to redo the
4365 work. The most common case of this happening, is a byterange
4366 request going through the proxy, and the origin server handles
4367 the byterange request. The proxy should ignore it.
4368 [Graham Leggett <minfrin sharp.fm>]
4370 *) Changed the threaded mpm to have child_main join to each of the
4371 worker threads to make sure the kids are all gone before child_main
4372 exits after a signal (cleanup from perform_idle_server_maintenance).
4373 This is an extension of Ryans recent commit to make the child_main
4376 *) Add more options to the ap_mpm_query function. This also allows MPMs to
4377 report if their threads are dynamic or static. Finally, this also
4378 implements a new API, ap_show_mpm, which returns the MPM that was
4379 required into the core. [Harrie Hazewinkel <harrie covalent.net>]
4381 *) Do not install the binaries from the support directory twice.
4382 [jun-ichiro hagino <itojun iijlab.net>]
4384 *) The ap_f* functions should flush data to the filter that is passed
4385 in, not the filter after the one passed in.
4386 [Ryan Morgan <rmorgan covalent.net>]
4388 *) Make ab work again by changing its native types to apr types and formats.
4389 [Justin Erenkrantz <jerenkrantz ebuilt.com>]
4391 *) Move the byterange filter and all of the supporting functions back
4392 to the HTTP module. The byterange filter turned out to be very
4393 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
4395 *) Make clean, distclean, and extraclean consistently according to the
4396 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz ebuilt.com>]
4398 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
4399 This may have been causing problems stopping processes in the threaded
4402 *) Fix content-length in mod_negotiation to a long int representation.
4405 *) Remove BindAddress from the default config file.
4406 [<giles nemeton.com.au>]
4408 *) Allow module authors to add a module to their Apache build using
4409 --with-module, without re-running buildconf. The syntax is:
4410 --with-module=module_type:/path/to/module.c
4411 The configure script will copy the module.c file to
4412 modules/module_type, and it will be added to the relevant Makefiles.
4413 currently, this only works for static modules. [Ryan Bloom]
4415 *) Changes required to make prefork clean up idle children properly.
4416 There was a window during which a starting worker deadlocks when
4417 an idle cleanup arrives before it completes init. Apache then keeps
4418 trying to cleanup the same deadlocked worker forever (until higher
4419 pids come along, but it still will never reduce below the deadlocked
4420 pid). Thus the number of children would not reduce to the correct
4421 idle level. [Paul J. Reder]
4423 Changes with Apache 2.0.16
4425 *) Change the default installation directory to /usr/local/apache2,
4426 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
4428 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
4431 *) Get MaxRequestsPerChild working with the Windows MPM.
4434 *) Make generic hooks to work, with mod_generic_hook_import/export
4435 experimental modules. [Ben Laurie, Will Rowe]
4437 *) Fix segfaults for configuration file syntax errors such as
4438 "<Directory>" followed by "</Directory" and
4439 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
4441 *) Cleanup the --enable-layout option of configure. This makes
4442 us use a consistent location for the config.layout file, and it
4443 makes configure more portable.
4444 [jun-ichiro hagino <itojun iijlab.net>]
4446 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
4447 csv/gnuplot format, rudimentary ssl support and various other tweaks
4448 to make results more true to what is measured. The upshot of this it
4449 turns out that 'ab' has often underreported the true performance of
4450 apache. Often by a order of magnitude :-) See talk/paper of Sander
4451 Temme at April ApacheCon 2001 for details.
4452 [Dirk-Willem van Gulik]
4454 *) Clean up mod_cgid's temporary request pool. Besides fixing a
4455 storage leak this ensures that some unnecessary pipes are closed.
4458 *) Performance: Add quick_handler hook. This hook is called at the
4459 very beginning of the request processing before location_walk,
4460 translate_name, etc. This hook is useful for URI keyed content
4461 caches like Mike Abbott's Quick Shortcut Cache.
4464 *) top_module global variable renamed to ap_top_module [Perl]
4466 *) Move ap_set_last_modified to the core. This is a potentially
4467 controversial change, because this is kind of HTTP specific. However
4468 many protocols should be able to take advantage of this kind of
4469 information. I expect that headers will need one more layer of
4470 indirection for multi-protocol work, but this is a small step in
4471 the right direction. [Ryan Bloom]
4473 *) Enable mod_status by default. This matches what Apache 1.3 does.
4476 *) Add a ScriptSock directive to the default config file. This is
4477 only enabled when mod_cgid is used.
4478 [Taketo Kabe <kabe sra-tohoku.co.jp>]
4480 Changes with Apache 2.0.15
4482 *) Untangled the buildconf script and eliminated the need for build's
4483 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
4484 libtool muck that is now under srclib/apr/build. [Roy Fielding]
4486 *) Win32: Don't accept more connections than we have worker threads
4490 *) Fix bug in the Unix threaded.c MPM that allowed child processes
4491 to fork() new child processes.
4494 *) SECURITY: Fix a major security problem with double-reverse lookup
4495 checking. Previously, a client connecting over IPv4 would not be
4496 matched properly when the server had an IPv6 listening socket.
4497 PR #7407 [Taketo Kabe <kiabe sra-tohoku.co.jp>]
4499 *) Change the way the beos MPM handles polling to allow it to stop and
4500 restart. Problem was the sockets being polled were being reset by
4501 the select call, so once it had accepted a connection it was no
4502 longer listening on the UDP socket we use for shutdown instructions.
4503 APR needs to be altered, patch on it's way. [David Reid]
4505 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
4506 on error exit from ap_getline(). Some other code got upset because
4507 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
4509 *) Handle ap_discard_request_body() being called more than once.
4510 [Greg Ames, Jeff Trawick]
4512 *) Get rid of an inadvertent close of file descriptor 2 in
4513 mod_mime_magic. [Greg Ames, Jeff Trawick]
4515 *) Add a hook, create_request. This hook allows modules to modify
4516 a request while it is being created. This hook is called for all
4517 request_rec's, main request, sub request, and internal redirect.
4518 When this hook is called, the r->main, r->prev, r->next
4519 pointers have been set, so modules can determine what kind of
4520 request this is. [Ryan Bloom]
4522 *) Cleanup the build process a bit more. The Apache configure
4523 script no longer creates its own helper scripts, it just
4525 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
4527 *) Stop the forced downgrade of the connection to HTTP/1.0 for
4528 proxy requests. [Graham Leggett]
4530 *) Avoid using sscanf to determine the HTTP protocol number in
4531 the common case because sscanf is a performance hog. From
4532 Mike Abbot's Accelerating Apache patch number 6.
4533 [Mike Abbot <mja trudge.engr.sgi.com>, Bill Stoddard]
4535 *) SECURITY: Fix a security exposure in mod_access. Previously when
4536 IPv6 listening sockets were used, allow/deny-from-IPv4-address rules
4537 were not evaluated properly (PR #7407). Also, add the ability to
4538 specify IPv6 address strings with optional prefix length on Allow
4539 and Deny. [Jeff Trawick]
4541 *) Enhance rotatelogs so that a UTC offset can be specified, and
4542 the logfile name can be formatted using strftime(3). (Brought
4543 forward from 1.3.) [Ken Coar]
4545 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
4546 DuplicateHandle on an IOCompletionPort (a practice which
4547 MS "discourages"). The new model does not rely on associating
4548 the completion port with the listening sockets, thus the
4549 completion port can be completely managed within the child
4550 process. A dedicated thread accepts connections off the network,
4551 then calls PostQueuedCompletionStatus() to wake up worker
4552 threads blocked on the completion port.
4555 *) Bring forward the --suexec-umask option which allows the
4556 builder to preset the umask for suexec processes. [Ken Coar]
4558 *) Add a -V flag to suexec, which causes it to display the
4559 compile-time settings with which it was built. (Only
4560 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
4562 *) Mod_include should always unset the content-length if the file is
4563 going to be passed through send_parsed_content. There is no to
4564 determine if the content will change before actually scanning the
4565 entire content. It is far safer to just remove the C-L as long
4566 as we are scanning it. [Ryan Bloom]
4568 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
4569 request and not Proxy-Authenticate.
4570 [Graham Leggett <minfrin sharp.fm>]
4572 Changes with Apache 2.0.14
4574 *) Fix content-length computation. We ONLY compute a content-length if
4575 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
4576 or we already have all the data. [Ryan Bloom]
4578 *) Report unbounded containers in the config file. Previously, a typo
4579 in the </container> directive could result in the rest of the config
4580 file being silently ignored, with undesired defaults used.
4583 *) Make the old_write filter use the ap_f* functions for the buffering.
4586 *) Move more code from the http module into the core server. This
4587 is core code, basically the default handler, the default input
4588 and output filters, and all of the core configuration directives.
4589 All of this code is required in order for the server to work, with or
4590 without HTTP. The server is closer to working without the HTTP
4591 module, although there is still more to do. [Ryan Bloom]
4593 *) Fix a number of SGI compile warnings throughout the server. Fix some
4594 bad parameters to apr_bucket_read(). Fix a bad statement in
4595 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
4596 consistently; we were mixing apr_time_t and time_t in invalid ways
4597 before. In load_file(), call apr_dso_error() instead of
4598 apr_strerror() so that we get a more specific string on some platforms.
4599 PR #6980 [Jeff Trawick]
4601 *) Allow modules to query the MPM about it's execution profile. This
4602 query API can and should be extended in the future, but for now,
4603 max_daemons, and threading or forking is a very good start.
4604 [Jon Travis <jtravis covalent.net>]
4606 *) Modify mod_include to send blocks of data no larger than 9k.
4607 Without this, mod_include will wait until the whole file is parsed,
4608 or the first tag is found to send any data to the client.
4609 [Paul J. Reder <rederpj raleigh.ibm.com>]
4611 *) Fix mod_info, so that <Directory> and <Location> directives are
4612 not displayed twice when displaying the current configuration.
4613 [Ryan Morgan <rmorgan covalent.net>]
4615 *) Add config directives to override DEFAULT_ERROR_MSG and
4616 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
4617 [Dan Rench <drench xnet.com>]
4619 *) Get mod_info building and loading on Win32. [William Rowe]
4621 *) Begin to move protocol independant functions out of mod_http. The goal
4622 is to have only functions that are HTTP specific in the http directory.
4625 Changes with Apache 2.0.13
4627 *) Don't assume that there will always be multiple calls to the byterange
4628 filter. It is possible that we will need to do byteranges with only
4629 one call to the filter. [Ryan Morgan <rmorgan covalent.net>]
4631 *) Move the error_bucket definition from the http module to the
4632 core server. Every protocol will need this ability, not just
4635 Changes with Apache 2.0.12
4637 *) Modify mod_file_cache to save pre-formatted strings for
4638 content-length and last-modified headers for performance.
4639 [Mike Abbot <mja trudge.engr.sgi.com>]
4641 *) Namespace protect IOBUFSIZ since it is exposed in the API.
4642 [Jon Travis <jtravis covalent.net>]
4644 *) Use "Basic" authentication instead of "basic" in ab, as the spec
4645 says we should. [Andre Breiler <andre.breiler rd.bbc.co.uk>]
4647 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
4648 without ever filling it out. This fixes PR 7271.
4649 [Taketo Kabe <kabe sra-tohoku.co.jp> and
4650 Cliff Woolley <cliffwoolley yahoo.com>]
4652 *) Add a couple of GCC attribute tags to printf style functions.
4653 [Jon Travis <jtravis covalent.net>]
4655 *) Add the correct language tag for interoperation with the Taiwanese
4656 versions of MSIE and Netscape. [Clive Lin <clive CirX.ORG>] PR#7142
4658 *) Migrate the perchild MPM to use the new apr signal child, and
4659 APR thread functions. [Ryan Bloom]
4661 *) Close one copy of the CGI's stdout before creating the new process.
4662 The CGI will still have stdout, because we have already dup'ed it.
4663 This keeps Apache from waiting forever to send the results of a CGI
4664 process that has forked a long-lived child process.
4665 [Taketo Kabe <kabe sra-tohoku.co.jp>]
4667 *) Remove the rest of the pthreads functions from the threaded MPM.
4668 This requires the APR support for a signal thread that was just
4671 *) Make mod_dir use a fixup for sending a redirect to the browser.
4672 Before this, we were using a handler, which doesn't make much
4673 sense, because the handler wasn't generating any data, it would
4674 either return a redirect error code, or DECLINED. This fits the
4675 current hooks better. [Ryan Morgan <rmorgan covalent.net>]
4677 *) Make the threaded MPM use APR threads instead of pthreads.
4680 *) Get mod_tls to the point where it actually appears to work in all cases.
4683 *) implement --enable-modules and --enable-mods-shared for "all" and
4684 "most". [Greg Stein]
4686 *) Move the threaded MPM to use APR locks instead of pthread locks.
4689 *) Rename mpmt_pthread to threaded. This is more in line with the
4690 fact that mpmt_pthread shouldn't be using pthreads directly, and
4691 it is a smaller name that doesn't tie into anything.
4694 *) Rename the module structures so that the exported symbol matches
4695 the file name, and it is easier to automate the installation
4696 process (generating LoadModule directives from the module filenames).
4699 *) Remove the coalesce filter. With the ap_f* functions, this filter
4700 is no longer needed. [Ryan Bloom]
4702 Changes with Apache 2.0.11
4704 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
4705 added feature of allowing a uid/gid per child process. If no
4706 uid/gid is specified, then Perchild behaves exactly like dexter.
4709 *) Get perchild building again. [Ryan Bloom]
4711 *) Don't disable threads just because we are using the prefork MPM.
4712 If somebody wants to compile without threads, they must now add
4713 --disable-threads to the configure command line. [Ryan Bloom]
4715 *) Begin to move the calls to update_child_status into common code, so
4716 that each individual MPM does not need to update the scoreboard itself.
4719 *) Allow mod_tls to compile under Unix boxes where openssl has been
4720 installed to the system include files.
4721 [Gomez Henri <new-httpd slib.fr>]
4723 *) Cleanup the mod_tls configure process. This should remove any need
4724 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
4725 configure doesn't check that yet. [Ryan Bloom]
4727 *) Add a very early prototype of SSL support (in mod_tls.c). It is
4728 vital that you read modules/tls/README before attempting to build
4731 *) Fix a potential seg fault on all platforms. David Reid fixed this
4732 on BEOS, but the problem could happen anywhere, so we don't want
4733 to #ifdef it. [Cliff Woolley <cliffwoolley yahoo.com>]
4735 *) Add new LogFormat directive, %D, to log time it takes to serve a
4736 request in microseconds. [Bill Stoddard]
4738 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
4739 SetOutputFilter. This corresponds nicely with the other Set
4740 directives, which operate on containers while the Add* directives
4741 tend to work directly on extensions. [Ryan Bloom]
4743 *) Cleanup the header handling a bit. This uses the apr_brigade_*
4744 functions for the buffering so that we don't need to compute
4745 the length of the headers before we actually create the header
4746 buffer. [Ryan Bloom]
4748 *) Allow filters to buffer data using the ap_f* functions. These have
4749 become macros that resolve directly to apr_brigade_*.
4752 *) Get the Unix MPM's to do a graceful restart again. If we are going
4753 to register a cleanup with ap_cleanup_scoreboard, then we have to
4754 kill the cleanup with the same function, and that function can't be
4755 static. [Ryan Bloom]
4757 *) Install all required header files. Without these, it was not
4758 possible to compile some modules outside of the server.
4761 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
4762 forward from 1.3 to 2.0, we missed a single line, which broke regex
4763 aliases. [Ryan Bloom]
4765 *) We have a poor abstraction in the protocol. This is a temporary
4766 hack to fix the bug, but it will need to be fixed for real. If
4767 we find an error while sending out a custom error response, we back
4768 up to the first non-OK request and send the data. Then, when we send
4769 the EOS from finalize_request_protocol, we go to the last request,
4770 to ensure that we aren't sending an EOS to a request that has already
4771 received one. Because the data is sent on a different request than
4772 the EOS, the error text never gets sent down the filter stack. This
4773 fixes the problem by finding the last request, and sending the data
4774 with that request. [Ryan Bloom]
4776 *) Make the server status page show the correct restart time, and
4777 thus the proper uptime. [Ryan Bloom]
4779 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
4780 should reduce the amount of duplicate code that is required to
4781 create CGI processes.
4782 [Paul J. Reder <rederpj raleigh.ibm.com>]
4784 *) ap_new_connection() closes the socket and returns NULL if a socket
4785 call fails. Usually this is due to a connection which has been
4786 reset. [Jeff Trawick]
4788 *) Move the Apache version information out of httpd.h and into release.h.
4789 This is in preparation for the first tag with the new tag and release
4790 system. [Ryan Bloom]
4792 *) Begin restructuring scoreboard code to enable adding back in
4793 the ability to use IPC other than shared memory.
4794 Get mod_status working on Windows again. [Bill Stoddard]
4796 *) Make mod_status work with 2.0. This will work for prefork,
4797 mpmt_pthread, and dexter. [Ryan Bloom]
4799 *) Correct a typo in httpd.conf.
4800 [Kunihiro Tanaka <tanaka apache.or.jp>] PR#7154
4802 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
4804 *) Get the correct IP address if ServerName isn't set and we can't
4805 find a fully-qualified domain name at startup.
4806 PR#7170 [Danek Duvall <dduvall eng.sun.com>]
4808 *) Make mod_cgid work with SuExec. [Ryan Bloom]
4810 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
4811 'extra' stat's for user/group since they should never occur, and now
4812 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
4813 volumes. [William Rowe]
4815 *) Adopt apr features to simplify mod_includes. This changes the
4816 behavior of the USER_NAME variable, unknown uid's are now reported
4817 as USER_NAME="<unknown>" rather than the old user#000 result.
4818 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
4820 *) Adopt apr features for simplifing mod_userdir, and accept the new
4821 Win32/OS2 exceptions without hiccuping. [William Rowe]
4823 *) Replace configure --with-optim option by using and saving the
4824 environment variable OPTIM instead. This is needed because configure
4825 options do not support multiple flags separated by spaces.
4828 *) Fix some byterange handling. If we get a byte range that looks like
4829 "-999999" where that is past the end of the file, we should return
4830 a PARTIAL CONTENT status code, and return the whole file as one big
4831 byterange. This matches the 1.3 handling now. [Ryan Bloom]
4833 *) Make the error bucket a real meta-data bucket. This means that the
4834 bucket length is 0, and a read returns NULL data. If one of these
4835 buckets is passed down after the headers are sent, this data will
4836 just be ignored. [Greg Stein]
4838 *) The prefork MPM wasn't killing child processes correctly if a restart
4839 signal was received while the process was serving a request. The child
4840 process would become the equivalent of a second parent process. If
4841 we break out of the accept loop, then we need to do die after cleaning
4842 up after ourselves. [Ryan Bloom]
4844 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
4845 restarts. [Ryan Bloom]
4847 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
4848 the most optimal APR_FINFO_wanted bits. This spares Win32 from
4849 performing very expensive owner, group and permission lookups
4850 and allows the server to function until these apr_finfo_t fields
4851 are implemented under Win32. [William Rowe]
4853 *) Support for typedsafe optional functions - that is functions exported by
4854 optional modules, which, therefore, may or may not be present, depending
4855 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
4856 for sample code. [Ben Laurie]
4858 *) filters can now report an HTTP error to the server. This is done
4859 by sending a brigade where the first bucket is an error_bucket.
4860 This bucket is a simple bucket that stores an HTTP error and
4861 a string. Currently the string is not used, but it may be needed
4862 to output an error log. The http_header_filter will find this
4863 bucket, and output the error text, and then return
4864 AP_FILTER_ERROR, which informs the server that the error web page
4865 has already been sent. [Ryan Bloom]
4867 *) If we get an error, then we should remove all filters except for
4868 those critical to serving a web page. This fixes a bug, where
4869 error pages were going through the byterange filter, even though
4870 that made no sense. [Ryan Bloom]
4872 *) Relax the syntax checking of Host: headers in order to support
4873 iDNS. PR#6635 [Tony Finch]
4875 *) Cleanup the byterange filter to use the apr_brigade_partition
4876 and apr_bucket_copy functions. This removes a lot of very messy
4877 code, and hopefully makes this filter more stable.
4880 *) Remove AddModule and ClearModuleList directives. Both of these
4881 directives were used to ensure that modules could be enabled
4882 in the correct order. That requirement is now gone, because
4883 we use hooks to ensure that modules are in the correct order.
4886 *) When SuExec is specified, we need to add it to the list of
4887 targets to be built. If we don't, then any changes to the
4888 configuration won't affect SuExec, unless 'make suexec' is
4889 specifically run. [Ryan Bloom]
4891 *) Cleaned out open_file from mod_file_cache, as apr now accepts
4892 the APR_XTHREAD argument to open a file for consumption by
4893 parallel threads on win32. [William Rowe]
4895 *) Correct a bug in determining when we follow symlinks. The code
4896 expected a stat -1 result, not an apr_status_t positive error.
4897 Also check if the APR_FINFO_USER fields are valid before we
4898 follow the link. [William Rowe]
4900 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
4901 mpm_common.c. These functions are only valid on some platforms,
4902 so they should not be in the main-line code. [Ryan Bloom]
4904 *) Remove ap_chdir_file(). This function is not thread-safe,
4905 and nobody is currently using it. [Ryan Bloom]
4907 *) Do not try to run make depend if there are no .c files in the
4908 current directory, doing so makes `make depend` fail.
4911 *) Update highperformance.conf to work with either prefork or
4912 pthreads mpms. [Greg Ames]
4914 *) Stop checking to see if this is a pipelined request if we know
4915 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
4916 This keeps us from making an extra read call when serving a 1.0
4917 request. [Ryan Bloom and Greg Stein]
4919 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
4920 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
4921 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
4923 *) Fix the RFC number mentioned when complaining about a missing
4924 Host: header. PR#7079 [Alexey Toptygin <alexeyt wam.umd.edu>]
4926 *) Fix an endless loop in ab which occurred when ab was posting
4927 and the server dropped the connection unexpectedly.
4930 *) Fix a segfault while handling request bodies in ap_http_filter().
4931 This problem has been seen with mod_dav usage as well as with
4932 requests where the body was just being discarded. [Jeff Trawick]
4934 *) Some adjustment on the handling and automatic setting (via
4935 hints.m4) of various compilation flags (eg: CFLAGS). Also,
4936 add the capability to specify flags (NOTEST_CFLAGS and
4937 NOTEST_LDFLAGS) which are used to compile Apache, but
4938 not used during the configuration process. Useful for
4939 flags like "-Werror". [Jim Jagielski]
4941 *) Stop using environment variables to force debug mode or
4942 no detach. We now use the -D command line argument to
4943 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
4944 [Greg Stein, Ryan Bloom]
4946 *) Change handlers to use hooks. [Ben Laurie]
4948 *) Stop returning copies of filenames from both apr_file_t and
4949 apr_dir_t. We pstrdup the filenames that we store in the
4950 actual structures, so we don't need to pstrdup the strings again.
4953 *) mod_cgi: Fix some problems where the wrong error value was being
4954 traced. [Jeff Trawick]
4956 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
4959 *) Add generic hooks. [Ben Laurie]
4961 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
4963 *) Fix a segfault caused by mod_ext_filter when the external filter
4964 program does not exist. [Jeff Trawick]
4966 *) Fix an output truncation error when on an HTTP >= 1.0 request an
4967 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
4968 was served through mod_charset_lite (or anything else that would
4969 create a transient bucket in this size range). ap_bucket_make_heap()
4970 silently failed (fixed), transient_setaside() discovered it, but
4971 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
4973 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
4974 is that some browsers send extra lines at the end of POST requests, and
4975 we don't want to delay sending data back to the user just because the
4976 browser isn't well behaved. [Ryan Bloom]
4978 *) Get SuEXEC working again. We can't send absolute paths to suExec
4979 because it refuses to execute those programs. SuEXEC also wasn't
4980 always recognizing configuration changes made using the autoconf
4983 *) Allow the buildconf process to find the config.m4 files in the correct
4984 order. Basically, we can now name config.m4 files as config\d\d.m4,
4985 and we will sort them correctly when inserting them into the build
4986 process. [Ryan Bloom]
4988 *) Get mod_cgid to use apr calls for creating the actual CGI process.
4989 This also allows mod_cgid to use ap_os_create_priviledged_process,
4990 thus allowing for SuExec execution from mod_cgid. Currently, we do
4991 not support everything that standard SuExec supports, but at least
4992 it works minimally now. [Ryan Bloom]
4994 *) Allow SuExec to be configured from the ./configure command line.
4997 *) Update some of the docs in README and INSTALL to reflect some of
4998 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley yahoo.com>]
5000 *) If we get EAGAIN returned from the call to apr_sendfile, then we
5001 need to call sendfile again. This gets us serving large files
5002 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
5004 *) Get the support programs building cleanly again.
5005 [Cliff Woolley <cliffwoolley yahoo.com>]
5007 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
5008 current directory logic now backs up over bin/ to determine the
5009 server root from the Apache.exe path.
5011 *) Apache/Win32 now follows the standard conventions of mod_foo.so
5012 loadable modules, dynamic libs are all named libfoo.dll, and the
5013 makefile.win populates the include, lib and libexec directories.
5015 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
5016 Apache gets IPv6 listening sockets by default. Additionally, the
5017 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
5018 numeric address strings (e.g., "Listen [fe80::1]:8080").
5021 *) Modify the install directory layout. Modules are now installed in
5022 modules/. Shared libraries should be installed in libraries/, but
5023 we don't have any of those on Unix yet. All install directories
5024 are modifyable at configure time. [Ryan Bloom]
5026 *) Install all header files in the same directory on Unix. [Ryan Bloom]
5028 *) Get the functions in server/linked into the server, regardless of
5029 which modules linked into the server. This uses the same hack
5030 for Apache that we use for APR and apr-util to ensure all of the
5031 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
5032 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
5033 the scripts a bit easier.
5036 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
5037 on the query, and remove IPv4 dependencies. [Jeff Trawick]
5039 *) Get all of the auth modules to the point that they will install and
5040 be loadable into the server. Our new build/install mechanism expects
5041 that all modules will have a common name format. The auth modules
5042 didn't use that format, so we didn't install them properly.
5045 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
5046 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
5048 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
5050 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
5051 after the end of the response. [Ryan Bloom]
5053 *) Get byterange requests working with responses that do not have a
5054 content-length. Because of the way byterange requests work, we have to
5055 have all of the data before we can actually do the byterange, so we
5056 can compute the content-length in the byterange filter.
5059 *) Get exe CGI's working again on Windows.
5062 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
5063 they keep track of whether or not their post config hook has been
5064 called before. Instead of a static variable (which is replaced when
5065 the DSO is loaded a second time), use userdata in the process pool.
5068 Changes with Apache 2.0a9
5070 *) Win32 now requires perl to complete the final install step for users
5071 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
5072 and installs the conf, htdocs and htdocs/manual directories.
5075 *) Make mod_include use a hash table to associate directive tags with
5076 functions. This allows modules to implement their own SSI tags easily.
5077 The idea is simple enough, a module can insert it's own tag and function
5078 combination into a hash table provided by mod_include. While mod_include
5079 parses an SSI file, when it encounters a tag in the file, it does a
5080 hash lookup to find the function that implements that tag, and passes
5081 all of the relevant data to the function. That function is then
5082 responsible for processing the tag and handing the remaining data back
5083 to mod_include for further processing.
5084 [Paul J. Reder <rederpj raleigh.ibm.com>]
5086 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
5087 fewer parameters: the local and remote socket addresses were removed
5088 from the parameter list because all required information is available
5089 via the APR socket. [Jeff Trawick]
5091 *) Distribution directory structure reorganized to reflect a
5092 normal source distribution with external install targets.
5095 *) The MPMs that need multiple segments of shared memory now create
5096 two apr_shmem_t variables, one for each shared memory allocation.
5097 the problem is that we can't determine how much memory will be required
5098 for shared memory allocations once we try to allocate more than one
5099 variable. The MM code automatically aligns the shared memory allocations,
5100 so we end up needing to pad the amount of shared memory we want based
5101 on how many variables will be allocated out of the shared memory segment.
5102 It is just easier to create a second apr_shmem_t variable, and two
5103 shmem memory blocks.
5106 *) Cleanup the export list a bit. This creates a single unified list of
5107 functions exported by APR. The export list is generated at configure
5108 time, and that list is then used to generate the exports.c file.
5109 Because of the way the export list is generated, we only export those
5110 functions that are valid on the platform we are building on.
5113 *) Enable logging the cookie with mod_log_config
5114 [Sander van Zoest <sander covalent.net>]
5116 *) Fix a segfault in mod_info when it reaches the end of the configuration.
5119 *) Added lib/aputil/ as a placeholder for utility functions which are not
5120 specific to the Apache HTTP Server (but do not make sense with APR).
5121 The first utility is "apu_dbm": a set of functions to work with DBM
5122 files. This first version can be compiled for SDBM or GDBM databases.
5125 *) Complete re-write of mod_include. This makes mod_include a filter that
5126 uses buckets directly. This has now served the FAQ correctly.
5127 [Paul Reder <rederpj raleigh.ibm.com>]
5129 *) Allow modules to specify the first filter in a sub_request when
5130 making the sub_request. This keeps modules from having to change the
5131 output_filter immediately after creating the sub-request, and therefore
5132 skip the sub_req_output_filter. [Ryan Bloom]
5134 *) Update ab to accept URLs with IPv6 literal address strings (in the
5135 format described in RFC 2732), and to build Host header fields in
5136 the same format. This allows IPv6 literal address strings to be
5137 used with ab. This support has been tested against Apache 1.3 with
5138 the KAME patch, but Apache 2.0 does not yet work with this format
5139 of the Host header field. [Jeff Trawick]
5141 *) Accomodate an out-of-space condition in the piped logs and the
5142 rotatelogs.c code, and no longer churn log processes for this
5143 condition. [Victor J. Orlikowski]
5145 *) Add support for partial writes with apr_sendfile() to core_output_filter.
5148 Changes with Apache 2.0a8
5150 *) Add a directive to mod_mime so that filters can be associated with
5154 *) Get multi-views working again. We were setting the path_info
5155 field incorrectly if we couldn't find the specified file.
5158 *) Fix 304 processing. The core should never try to send the headers
5159 down the filter stack. Always, just setup the table in the request
5160 record, and let the header filter convert it to data that is ready
5164 *) More fixes for the proxy. There are still bugs in the proxy code,
5165 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
5169 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
5172 *) APR: Add new apr_getopt_long function to handle long options.
5173 [B. W. Fitzpatrick <fitz red-bean.com>]
5175 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
5176 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
5177 hostname resolution/address string parsing and building
5178 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
5179 of one of the apr_sockaddr_t structures for a socket. Change
5180 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
5182 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
5183 I have proxied pages with it, cleanup will commence soon.
5186 *) Make the proxy work with filters. This isn't perfect, because we
5187 aren't dealing with the headers properly. [Ryan Bloom]
5189 *) Do not send a content-length iff the C-L is 0 and this is a head
5190 request. [Ryan Bloom]
5192 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
5193 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
5195 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
5197 *) Get the default_handler to stop trying to deal with HEAD requests.
5198 The idea is to let the content-length filter compute the C-L before
5199 we try to send the data. If we can get the C-L correctly, then we
5200 should send it in the HEAD response.
5203 *) The Header filter can now determine if a body should be sent based
5204 on r->header_only. The general idea of this is that if we delay
5205 deciding to send the body, then we might be able to compute the
5206 content-length correctly, which will help caching proxies to cache
5207 our data better. Any handler that doesn't want to try to compute
5208 the content-length can just send an EOS bucket without data and
5209 everything will just work.
5212 *) Add the referer to the error log if one is available.
5213 [Markus Gyger <mgyger itr.ch>]
5215 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
5216 change, the root of the configuration tree has been exposed to modules
5218 [Ryan Morgan <rmorgan covalent.net>]
5220 *) Get the core_output_filter to use the bucket interface directly.
5221 This keeps us from calling the content-length filter multiple times
5222 for a simple static request.
5225 *) We are sending the content-type correctly now.
5226 [Ryan Bloom and Will Rowe]
5228 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
5229 a bogus bytes-sent value when the only thing being sent was trailers
5230 and writev() returned an error (or EAGAIN). [Jeff Trawick]
5232 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
5233 hints file to determine which platforms define
5234 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
5237 *) APR: add apr_get_home_directory() [Jeff Trawick]
5239 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
5241 *) Not all platforms have INADDR_NONE defined by default. Apache
5242 used to make this check and define INADDR_NONE if appropriate,
5243 but APR needs the check too, and I suspect other applications will
5244 as well. APR now defines APR_INADDR_NONE, which is always a valid
5245 value on all platforms.
5246 [Branko Èibej <brane xbc.nu>]
5248 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
5249 [Shuichi Kitaguchi <ki hh.iij4u.or.jp>]
5251 *) Relax the syntax checking of Host: headers in order to support
5252 iDNS. PR#6635 [Tony Finch]
5254 *) When reading from file buckets we convert to an MMAP if it makes
5255 sense. This also simplifies the default handler because the
5256 default handler no longer needs to try to create MMAPs.
5259 *) BUFF has been removed from the main server. The BUFF code will remain
5260 in the code until it has been purged from the proxy module as well.
5263 *) Byteranges have been completely re-written to be a filter. This
5264 has been tested, and I believe it is working correctly, but it could
5265 doesn't work for the Adobe Acrobat plug-in. The output almost matches
5266 the output from 1.3, the only difference being that 1.3 includes
5267 a content-length in the response, and this does not.
5270 *) APR read/write functions and bucket read functions now operate
5271 on unsigned integers, instead of signed ones. It doesn't make
5272 any sense to use signed ints, because we return the error codes,
5273 so if we have an error we should report 0 bytes read or written.
5276 *) Always compute the content length, whether it is sent or not.
5277 The reason for this, is that it allows us to correctly report
5278 the bytes_sent when logging the request. This also simplifies
5279 content-length filter a bit, and fixes the actual byte-reporing
5280 code in mod_log_config.c
5283 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
5284 it says, because it was only used by EOS and FLUSH buckets. Since
5285 neither of those are required at the end of a brigade, this was
5286 really signifying FLUSH_THE_DATA, but that can be determined better
5287 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
5288 buckets now return a length of 0, which is actually the amount of data
5289 read, so they make more sense.
5292 *) Allow the core_output_filter to save some data past the end of a
5293 request. If we get an EOS bucket, we only send the data if it
5294 makes sense to send it. This allows us to pipeline request
5295 responses. As a part of this, we also need to allocate mmap
5296 buckets out of the connection pool, not the request pool. This
5297 allows the mmap to outlive the request.
5300 *) Make blocking and non-blocking bucket reads work correctly for
5301 sockets and pipes. These are the only bucket types that should
5302 have non-blocking reads, because the other bucket types should
5303 ALWAYS be able to return something immediately.
5306 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
5307 server, but use Ctrl+Break to initiate a graceful restart
5308 instead of duplicating behavior. [John Sterling]
5310 *) Patch mod_autoindex to set the Last-Modified header based on
5311 the directory's mtime, and add the ETag header. [William Rowe]
5313 *) Merge the 1.3 patch to add support for logging query string in
5314 such a way that "%m %U%q %H" is the same as "%r".
5317 *) Port three log methods from mod_log_config 1.3 to 2.0:
5318 CLF compliant '-' byte count, method and protocol.
5321 *) Add a new LogFormat directive, %c, that will log connection
5322 status at the end of the response as follows:
5323 'X' - connection aborted before the response completed.
5324 '+' - connection may be kept-alive by the server.
5325 '-' - connection will be closed by the server.
5328 *) Expand APR for WinNT to fully accept and return utf-8 encoded
5329 Unicode file names and paths for Win32, and tag the Content-Type
5330 from mod_autoindex to reflect that charset if the feature
5331 macro APR_HAS_UNICODE_FS is true. [William Rowe]
5333 *) Compute the content length (and add appropriate header field) for
5334 the response when no content length is available and we can't use
5335 chunked encoding. [Jeff Trawick]
5337 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
5338 so that content input filters get dechunked data when using
5339 the default handler. Also removed REQUEST_CHUNKED_PASS.
5342 *) Add mod_ext_filter as an experimental module. This module allows
5343 the administrator to use external programs as filters. Currently,
5344 only filtering of output is supported. [Jeff Trawick]
5346 *) Most Apache functions work on EBCDIC machines again, as protocol
5347 data is now translated (again). [Jeff Trawick]
5349 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
5350 the EBCDIC support. They are noops on ASCII machines, so this
5351 type of translation doesn't have to be surrounded by #ifdef
5352 CHARSET_EBCDIC. [Jeff Trawick]
5354 *) Fix mod_include. tag commands work again, and the server will
5355 send the FAQ again. This also allows mod_include to set aside
5356 buckets that include partial buckets.
5357 [Ryan Bloom and David Reid]
5359 *) Add suexec support back. [Manoj Kasichainula]
5361 *) Lingering close now uses the socket directly instead of using
5362 BUFF. This has been tested, but since all we can tell is that it
5363 doesn't fail, this needs to be really hacked on.
5366 *) Allow filters to modify headers and have those headers be sent to
5367 the client. The idea is that we have an http_header filter that
5368 actually sends the headers to the network. This removes the need
5369 for the BUFF to send headers.
5372 *) Charset translation: mod_charset_lite handles translation of
5373 request bodies. Get rid of the xlate version of ap_md5_digest()
5374 since we don't compute digests of filtered (e.g., translated)
5375 response bodies this way anymore. (Note that we don't do it at
5376 all at the present; somebody needs to write a filter to do so.)
5379 *) Input filters and ap_get_brigade() now have a input mode parameter
5380 (blocking, non-blocking, peek) instead of a length parameter.
5383 *) Update the mime.types file to the registered media types as
5384 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp home.net>,
5387 *) Namespace protect some macros declared in ap_config.h
5390 *) Support HTTP header line folding with input filtering.
5393 *) Mod_include works again. This should still be re-written, but at
5394 least now we can serve an SHTML page again.
5397 *) Begin to remove BUFF from the core. Currently, we keep a pointer
5398 to both the BUFF and the socket in the conn_rec. Functions that
5399 want to use the BUFF can, functions that want to use the socket,
5400 can. They point to the same place.
5403 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
5404 [Tomas "Ögren" <stric ing.umu.se>]
5406 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
5407 associated pool goes away. (APR pipes on OS/2 were already had this
5408 logic.) This resolvs a fatal file descriptor leak with CGIs.
5411 *) The final line of the config file was not being read if there was
5412 no \n at the end of it. This was caused by apr_fgets returning
5413 APR_EOF even though we had read valid data. This is solved by
5414 making cfg_getline check the buff that was returned from apr_fgets.
5415 If apr_fgets return APR_EOF, but there was data in the buf, then we
5416 return the buf, otherwise we return NULL.
5419 *) Piped logs work again in the 2.0 series.
5422 *) Restore functionality broken by the mod_rewrite security fix:
5423 rewrite map lookup keys and default values are now expanded
5424 so that the lookup can depend on the requested URI etc.
5425 PR #6671 [Tony Finch]
5427 *) SECURITY: Tighten up the syntax checking of Host: headers to fix a
5428 security bug in some mass virtual hosting configurations
5429 that can allow a remote attacker to retrieve some files
5430 on the system that should be inaccessible. [Tony Finch]
5432 *) Add a pool bucket type. This bucket is used for data allocated out
5433 of a pool. If the pool is cleaned before the bucket is destroyed, then
5434 the data is converted to a heap bucket, allowing it to survive the
5438 *) Add a flush bucket. This allows modules to signal that the filters
5439 should all flush whatever data they currently have. There is no way
5440 to actually force them to do this, so if a filter ignores this bucket,
5441 that's life, but at least we can try with this.
5444 *) Add an output filter for sub-requests. This filter just strips the
5445 EOS bucket so that we don't confuse the main request's core output
5446 filter by sending multiple EOS buckets. This change also makes sub
5447 requests start to send EOS buckets when they are finished.
5450 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
5451 makes ap_bucket_destroy a return void, which is okay because it
5452 used to always return APR_SUCCESS, and nobody ever checked its
5453 return value anyway.
5454 [Cliff Woolley <cliffwoolley yahoo.com>]
5456 *) Remove the index into the bucket-type table from the buckets
5457 structure. This has now been replaced with a pointer to the
5458 bucket_type. Also add some macros to test the bucket-type.
5461 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
5462 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
5463 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
5464 All _VAR_ flavors changes to _DATA to be absolutely clear.
5467 *) Add support for /, //, //servername and //server/sharename
5468 parsing of <Directory> blocks under Win32 and OS2.
5469 [Tim Costello, William Rowe, Brian Harvard]
5471 *) Remove the function pointers from the ap_bucket type. They have been
5472 replaced with a global table. Modules are allowed to register bucket
5473 types and use then use those buckets.
5476 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
5477 once we finish writing the request body to the cgi child process;
5478 otherwise, the client doesn't hit EOF on stdin. Small request bodies
5479 worked without this change (for reasons I don't understand), but large
5480 ones didn't. [Jeff Trawick]
5482 *) Remove file bucket specific information from the ap_bucket type.
5483 This has been moved to a file_bucket specific type that hangs off
5484 the data pointer in the ap_bucket type.
5487 *) Input filtering now has a third argument. This is the amount of data
5488 to read from lower filters. This argument can be -1, 0, or a positive
5489 number. -1 means give me all the data you have, I'll deal with it and
5490 let you know if I need more. 0 means give me one line and one line
5491 only. A positive number means I want no more than this much data.
5493 Currently, only 0 and a positive number are implemented. This allows
5494 us to remove the remaining field from the conn_rec structure, which
5498 *) Big cleanup of the input filtering. The goal is that http_filter
5499 understands two conditions, headers and body. It knows where it is
5500 based on c->remaining. If c->remaining is 0, then we are in headers,
5501 and http_filter returns a line at a time. If it is not 0, then we are
5502 in body, and http_filter returns raw data, but only up to c->remaining
5503 bytes. It can return less, but never more.
5504 [Greg Ames, Ryan Bloom, Jeff Trawick]
5506 *) mod_cgi: Write all of the request body to the child, not just what
5507 the kernel would accept on the first write. [Jeff Trawick]
5509 *) Back out the change that moved the brigade from the core_output_filters
5510 ctx to the conn_rec. Since all requests over a given connection
5511 go through the same core_output_filter, the ctx pointer has the
5515 *) Fix another bug in the send_the_file() read/write loop. A partial
5516 send by apr_send would cause unsent data in the read buffer to
5517 get clobbered. Complete making send_the_file handle partial
5518 writes to the network.
5521 *) Fix a couple of type fixes to allow compilation on AIX again
5522 [Victor J. Orlikowski <v.j.orlikowski gte.net>]
5524 *) Fix bug in send_the_file() which causes offset to be ignored
5525 if there are no headers to send.
5528 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
5529 filter. Useful for supporting Windows 9* with a binary
5530 compiled on Windows NT.
5533 Changes with Apache 2.0a7
5535 *) Reimplement core_output_filter to buffer/save bucket brigades
5536 across multiple calls to the core_filter. The brigade will be
5537 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
5538 thresholds are hit or the EOS bucket is received.
5541 *) Create experimental filter (buffer_filter) that coalesces bytes
5542 into one large buffer before invoking the next filter in the
5543 chain. This filter is particularly useful with the current
5544 implementation of mod_autoindex when it inserted above the
5545 chunk_filter. mod_autoindex generates a lot of brigades that
5546 containing buckets holding just a few bytes each. The
5547 buffer_filter coalesces these buckets into a single large bucket.
5550 *) Add apr_sendfile() support into the core_output_filter.
5553 *) Add apr_sendv() support into the core_output_filter.
5556 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
5557 [Mike Abbott <mja sgi.com>]
5559 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
5560 make much sense, because Apache uses buckets instead of BUFFs now.
5563 *) send_the_file now falls back to a read/write loop on platforms that
5564 do not have sendfile.
5565 [Ryan Bloom and Brian Havard]
5567 *) Install apachectl correctly, and substitute the proper values so
5568 that it works again. [Ryan Bloom]
5570 *) Better(??) handle platforms that lack sendfile().
5573 *) APR now has UUID generation/formatting/parsing support.
5576 *) Begin the http_filter. This is an input filter that understands
5577 the absolute basic amount required to parse an HTTP Request. The
5578 goal is to be able to split headers from request body before passing
5579 the data back to the other filters.
5582 *) Bring forward from 1.3.13 the config directory implementation
5585 *) install apxs if it is created
5588 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
5589 conversions. [William Rowe]
5591 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
5592 ap_add_output_filter(). [Jeff Trawick]
5594 *) Multiple build and configuration fixes
5597 -add datadir and localstatedir substitutions
5599 -fix logfilename misspelling
5600 -fix evaluation of installation dir variables and
5601 -replace $foobar by $(foobar) to be usefull in the makefile
5605 -add rules for cross-compiling in rules.mk. Okay, rule to check for
5606 $CC_FOR_BUILD is still missing
5607 -use CHECK_TOOL instead of CHECK_PROG for ranlib
5608 -add missing "AR=@AR@" to severaly Makefile.in's
5609 -cache result for "struct rlimit"
5610 -compile all helper programs with native and cross compiler
5611 and use the native version to generate header file
5612 ["Rüdiger" Kuhlmann <Tadu gmx.de>]
5614 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
5616 ["Rüdiger" Kuhlmann <Tadu gmx.de>]
5618 *) Fix a bug where a client which only sends \n to delimit header
5619 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
5620 message. Start working on ebcdic co-existance with input
5622 [William Rowe, Greg Ames]
5624 *) If mod_so is enabled in the server always create libexec, even
5625 if there are no modules installed in this directory. This is a
5626 requirement for APXS to work correctly.
5629 *) Connection oriented output filters are now stored in the
5630 conn_rec instead of the request_rec. This allows us to add the
5631 output filter in the pre-connection phase instead of the
5632 post_read_request phase, which keeps us from trying to write an
5633 error page before we have a filter to write to the network.
5634 [Ryan Bloom, Jeff Trawick, and Greg Ames]
5636 *) Cleaning up an mmap bucket no longer deletes the mmap. An
5637 mmap can be used across multiple buckets (default_handler with
5638 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
5639 the mmap itself can't be associated with the bucket.
5642 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
5645 *) Radical surgery to improve mod_isapi support under Win32.
5646 Includes a number of newer ServerSupportFunction calls, support
5647 for ReadClient (in order to retrieve POSTs greater than 48KB),
5648 and general bug fixes to more reliably load ISAPI .dll's and
5649 prevent leaking handle resources. Note: There are still
5650 discrepancies between IIS's and Apache's ServerVariables, and
5651 async calls are still not supported. Additional warnings are
5652 logged to facilitate debugging of unsupported ISAPI calls.
5655 *) Add input filtering to Apache. The basic idea for the input
5656 filters is the same as the ideas for output filters. The biggest
5657 difference is that instead of calling ap_pass_brigade, ap_get_brigade
5658 should be called, and the order of execution for the filter itself is
5659 different. When writing an output filter, a brigade is passed in,
5660 and filters operate directly on that brigade, when done, they call
5661 ap_pass_brigade. Input filters are the exact opposite. Because input
5662 is not a push operation, filters first call ap_get_brigade. When this
5663 function returns, the input filter will be left with a valid brigade.
5664 The input filter should then operate on the brigade, and return.
5667 *) Fix building on BSD/OS using its native make. The build system
5668 falls back to the BSD .include directive on that host platform.
5671 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
5672 SHA1 and plaintext password encodings. Make feature tests a
5673 bit more flexible. [William Rowe]
5675 *) Charset translation: mod_charset_lite handles output content
5676 translation in a filter. mod_charset_lite no longer ignores
5677 subrequests. A bunch of cruft related to BUFF's support for
5678 translating request and response bodies was removed.
5681 *) Move the addition of the CORE filter to the post_read_request
5682 hook in http_core.c. This removes the need to add the filter in
5683 multiple places and allows for an SSL module to be added much
5684 simpler. [Ryan Bloom]
5686 *) SECURITY [CVE-2000-0913] (cve.mitre.org):
5687 Fix a security problem that affects certain configurations of
5688 mod_rewrite. If the result of a RewriteRule is a filename that
5689 contains expansion specifiers, especially regexp backreferences
5690 $0..$9 and %0..%9, then it may be possible for an attacker to
5691 access any file on the web server. [Tony Finch]
5693 *) Fix a bug where errors that are detected during early request parsing
5694 don't produce visible HTTP error messages at the browser, because
5695 the core_filter wasn't present. [Greg Ames]
5697 *) Provide apr_socklen_t as a portability aid.
5698 [Victor J. Orlikowski]
5700 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
5701 as well as a comment arg to the add, adduser and update cmds.
5702 update allows the user to clear or preserve pw/groups/comment.
5703 Fixed a bug in dbmmanage that prevented the check option from
5704 parsing a password followed by :group... text. Corrected the
5705 seed calcualation for Win32 systems, and added -lsdbm support.
5708 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
5711 *) Avoid a segfault when parsing .htaccess files. An
5712 uninitialized tree pointer was passed to ap_build_config().
5715 *) Change the way that inet_addr & inet_network are checked for
5716 in APR's configure process to allow BeOS BONE to correctly
5717 find them. With this change BeOS BONE now builds from source
5718 with no problems. [David Reid]
5720 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
5721 the end of the parameters to execve() was stored in the wrong
5722 location, overlaying the storage beyond the newargs[] array and
5723 also passing uninitialized storage to execve(), which would
5724 sometimes fail with EFAULT. [Jeff Trawick]
5726 *) Fix a bug parsing configuration file containers. With a sequence
5727 like this in the config file
5729 <IfModule mod_kilroy.c>
5732 <IfModule mod_lovejoy.c>
5737 the second container would be terminated at the blank line due to
5738 sediment in the buffer from reading the prior </IfModule> and an
5739 error message would be generated for the real </IfModule> for the
5740 second container. Also due to this problem, any two characters
5741 could be used for "</" in the close of a container.
5744 *) ap_add_filter prototype changed to remove the ctx pointer. The
5745 pointer still remains in the filter structure, but it can not be
5746 a part of the ap_add_filter prototype. The reason is that when
5747 the core uses AddFilter to add a filter to the stack it doesn't
5748 know how to allocate the ctx pointer, or even how much memory should
5749 be allocated. The filters will have to be responsible for allocating
5750 the ctx memory when they need it.
5753 *) Add an AddFilter directive. This directive takes a list of filters
5754 that should be activated for the requested resource.
5757 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
5758 some other platforms). [Jeff Trawick]
5760 *) Modify mod_include to be a filter. Currently, it has only been tested
5761 on actual files, but it should work for CGI scripts too.
5764 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
5765 writes. apr_flush() for Unix: handle interrupted writes.
5768 *) NameVirtualHost can now take "*" as an argument instead of
5769 an IP address. This allows you to create a purely name-based
5770 virtual hosting server that does not have any IP addresses in
5771 the configuration file and which ignores the local address
5772 of any connections. PR #5595, PR #4455 [Tony Finch]
5774 *) Fix some compile warnings in mod_mmap_static.c
5775 [Mike Abbott <mja sgi.com>]
5777 *) Fix chunking problem with CGI scripts. The general problem was that
5778 the CGI modules were adding an EOS bucket and then the core added an
5779 EOS bucket. The chunking filter finalizes the chunked response when it
5780 encounters an EOS bucket. Because two EOS buckets were sent, we
5781 finalized the response twice. The fix is to make sure we only send one
5782 EOS, by utilizing a flag in the request_rec.
5785 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
5786 and Win32. Previously, the first read from an apr_file_t set up via
5787 apr_put_os_file() would return a '\0'. [Jeff Trawick]
5789 *) Mod_cgid now creates a single element bucket brigade, with a pipe
5790 bucket, instead of using BUFF's and ap_r*.
5793 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
5794 [Mike Abbott <mja sgi.com>]
5796 *) Remove ap_bopenf from buff code. This required modifying the file_cache
5797 code to use APR file's directly instead of going through BUFFs.
5800 *) Fix compile break on some platforms for mod_mime_magic.c
5801 [John K. Sterling <sterling covalent.net>]
5803 *) Fix merging of AddDefaultCharset directive.
5804 PR #5872 (1.3) [Jun Kuriyama <kuriyama imgsrc.co.jp>]
5806 *) Minor revamp of the rlimit sections of code. We now test
5807 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
5808 is now "available" even if the platform doesn't support
5809 the rlimit family (it's just a noop though). [Jim Jagielski]
5811 *) Migrate the pre-selection of which MPM to use for specific
5812 platforms to hints.m4, which contains (or should contain)
5813 all platform specific "hints". [Jim Jagielski]
5815 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
5818 *) Add tables with non-string/binary values to APR.
5821 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
5824 *) Update PCRE to version 3.2. [Ryan Bloom]
5826 *) Change the way buckets' destroy functions are called so that
5827 they can be more directly used when changing the type of a
5828 bucket in place. [Tony Finch]
5830 *) Add generic support for reference-counting the resources used by
5831 buckets, and alter the HEAP and MMAP buckets to use it. Change
5832 the way buckets are initialised to support changing the type of
5833 buckets in place, and use it when setting aside TRANSIENT buckets.
5834 Change the implementation of TRANSIENT buckets so that it can be
5835 mostly shared with IMMORTAL buckets, which are now implemented.
5838 Changes with Apache 2.0a6
5840 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
5842 *) Add a chunking filter to Apache. This brings us one step closer
5843 to removing BUFF. [Ryan Bloom]
5845 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
5846 added to the stack is the last filter to be called. [Ryan Bloom]
5848 *) Apache 2.0 has been completely documented using Scandoc. The
5849 docs can be generated by running 'make docs'. [Ryan Bloom]
5851 *) Add filtered I/O to Apache. This is based on bucket brigades,
5852 Currently the buckets still use BUFF under the covers, but that
5853 should change quickly. The only currently written filter is the
5854 core filter which just calls ap_bwrite. [The Apache Group]
5856 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
5857 built with thread support. [Jeff Trawick]
5859 *) Abort configuration if --with-layout was specified and there's
5860 no layout definition file. [Ken Coar]
5862 *) Add support for '--with-port=n' option to configure. [Ken Coar]
5864 *) Add support for extension methods for the Allow response header
5865 field, and an API routine for accessing r->allowed and the
5866 list of extension methods in a unified manner. [Ken Coar]
5868 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
5869 [Rob Simonson <simo us.ibm.com>]
5871 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
5872 APACHE_XLATE builds. [Jeff Trawick]
5874 *) A configuration file parsing problem was fixed. When the
5875 configuration file started with an IfModule/IfDefine container,
5876 only the last statement in the container would be retained.
5879 Changes with Apache 2.0a5
5881 *) Perchild is serving pages after passing them to different child
5882 processes. There are still a lot of bugs, but this does work. I
5883 have made requests against the same installation of Apache, and had
5884 different servers use different user IDs to serve the responses.
5885 This change moves to using socketpair instead of an AF_UNIX socket.
5888 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
5889 It can't seem to pass between child processes yet, but I think we
5890 are closer now than before. This moves us back to using Unix
5891 Domain Sockets. [Ryan Bloom]
5893 *) libapr functions and types renamed with apr_ prefix.
5894 #include "apr_compat.h" for 1.3.x backwards compat
5897 *) Fix problems with APR sockaddr handling on Win32. It didn't always
5898 return the right information on the local socket address.
5899 [Gregory Nicholls <gnicholls level8.com>]
5901 *) ap_recv() on Win32: Set bytes-read to 0 on error.
5902 [Gregory Nicholls <gnicholls level8.com>]
5904 *) Add an option to not detach from the controlling terminal without
5905 going into single process mode. This allows for much easier
5906 debugging of the process startup code. [Ryan Bloom]
5908 *) ab: don't use perror() to report the failure of an APR function.
5911 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
5912 scoreboard on graceful restarts.
5915 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
5916 An invalid ap_proc_t was passed to ap_create_process().
5919 *) Allow modules to register filters. Those filters are still
5920 never called, but this is a step in the right direction.
5921 [Ryan Bloom and Greg Stein]
5923 *) Register the mod_cgid daemon process for cleanup so that it is
5924 killed at termination if it does not die when the parent gets
5925 SIGTERM. This change is to fix occasional problems where the
5926 process stays around. Bugs in similar logic in mod_rewrite and
5927 mod_include were also fixed. [Jeff Trawick]
5929 *) Fix a bug in the time handling. Basically, we were imploding a time
5930 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
5931 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
5932 uses those two fields to adjust the time value. Because of the HTTP
5933 spec, both of those values can be zero'ed out safely. This fixes
5934 the bug correctly. [Ryan Bloom]
5936 *) Fix a couple of place in the Windows code where the wrong error
5937 code was being returned. [Gregory Nicholls <gnicholls level8.com>]
5939 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
5941 *) Added the APR_EOL_STR macro for platform dependent differences in
5942 logfiles and other raw text (such as all APR files). Fixes logfiles
5943 not terminated with cr/lf sequences in Win32. [William Rowe]
5945 *) Move all strings functions in APR to src/lib/apr/strings and create
5946 apr_strings.h for the prototypes. [Ryan Bloom]
5948 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
5949 to repeat the syscall until we stop getting EINTR. I noticed a
5950 related problem at termination (SIGTERM) on FreeBSD when using
5951 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
5952 implementation work properly with child init. Previously, ap_lock()
5953 was essentially a no-op because all children were using different
5954 locks and thus nobody ever blocked. [Jeff Trawick]
5956 *) The htdocs/ tree has been moved out of the CVS source tree into
5957 a separate area for easier development. This has NO EFFECT on
5958 end-users or Apache installations. [Ken Coar]
5960 *) Integrate the mod_dav module for WebDAV protocol handling. This
5961 adds the dav and dav_fs modules, the SDBM library, and additional
5962 XML handling utilities. [Greg Stein]
5964 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
5967 *) Update the lib/expat-lite/ library (bring forward changes from
5968 the Apache 1.3 repository). [Greg Stein]
5970 *) If sizeof(long long) == sizeof(long), then prefer long in APR
5971 configure.in. [Dave Hill <ddhill zk3.dec.com>]
5973 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
5974 machines where sendfile is detected, but nobody has written ap_sendfile.
5975 [Dave Hill <ddhill zk3.dec.com>]
5977 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
5979 *) ab would start up more connections than needed, then quit when the
5980 desired number were finished. Also fixed a logic error involving
5981 ab keepalives. [Victor J. Orlikowski]
5983 *) WinNT: Implement non-blocking pipes with timeouts to communicate
5984 with CGIs. Apache 2.0a4 had non-blocking pipes but without
5985 timeouts (i.e, if a timeout was specified, the pipe reverted to
5986 a full blocking pipe). Now the behaviour is more in line with
5987 Unix non-blocking pipes.
5990 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
5991 cache open file handles along with accept socket reuse enables
5992 Apache 2.0 to serve non-keepalive requests for static files at
5993 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
5994 and Apache 2.0 will serve almost 1200 rps on my system).
5997 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
5998 supports two config directives, mmapfile (same behavious as
5999 mod_mmap_static) and cachefile. Use the cachefile directive
6000 to cache open file handles. This directive only works on systems
6001 that have implemented the ap_sendfile API. cachefile works today
6002 on Windows NT, but has not been tested on any flavors of Unix.
6005 *) Cleanup the configuration. With the last few changes the
6006 configuration process automatically:
6007 inherits information about how to build from APR. Allowing
6008 APR to inform Apache that it should or should not use -ldl
6010 Detects which mod_cgi should be used mod_cgi or mod_cgid,
6011 based on the threading model
6013 Apache calls APR's configure process before finishing it's
6014 configuration processing, allowing for more information flow
6019 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
6020 with non-zero argument makes the socket non-blocking. BeOS and
6021 OS/2 already worked this way. [Jeff Trawick]
6023 *) ap_close() now calls ap_flush() for buffered files, so write
6024 operations work a whole lot better on buffered files.
6027 *) Fix error messages issued from MPMs which explain where to change
6028 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
6031 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
6032 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
6033 now the way that the blocking state of a pipe is manipulated.
6034 ap_block_pipe() is gone. [Jeff Trawick]
6036 *) Correct the problem where the only local host name that the IP stack
6037 can discover are 'undotted' private names. If no fully qualified
6038 domain name can be identified, the default ServerName will be set to
6039 the machine's IP address string. A warning is always provided if the
6040 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
6042 *) Repair problems with config file processing which caused segfault
6043 at init when virtual hosts were defined and which caused ServerName to
6044 be ignored when there was no valid DNS setup. [Jeff Trawick]
6046 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
6048 *) Add ap_sendfile implementation for AIX
6049 [Victor J. Orlikowski]
6051 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
6052 apr_network_io.h, and apr_thread_proc.h.
6053 [Tyler J. Brooks <tylerjbrooks home.com>, Jeff Trawick]
6055 *) Bring the allocation and pool debugging code back into a working
6056 state. This will need to be tested as so far it's only been used on
6059 *) Change configuration command setup to be properly typesafe when in
6060 maintainer mode. Note that this requires a compiler that can initialise
6061 unions. [Ben Laurie]
6063 *) Turn on buffering for config file reads. Part of this was to
6064 repair buffered I/O support in Unix and implement buffered
6065 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
6067 *) Win32: Fix problem where UTC offset was not being set correctly
6068 in the access log. Problem reported on news group by Jerry Baker.
6071 *) Fix segfault when reporting this type of syntax error:
6072 "</container> without matching <container> section", where
6073 container is VirtualHost or Directory or whatever.
6076 *) SECURITY [CAN-2000-1204] (cve.mitre.org):
6077 Prevent the source code for CGIs from being revealed when
6078 using mod_vhost_alias and the CGI directory is under the document root
6079 and a user makes a request like http://www.example.com//cgi-bin/cgi
6080 as reported in <news:960999105.344321 ernani.logica.co.uk>
6083 *) Add support for the new Beos NetwOrking Environment (BONE)
6086 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
6087 final input char is incomplete; ap_bwrite_xlate() now handles
6088 incomplete final input chars. [Jeff Trawick]
6090 *) Yet another update to saferead/halfduplex stuff -- need to ensure
6091 that a bhalfduplex call occurs before logging or else DNS and
6092 such can delay the last packet of the response. [Dean Gaudet]
6094 *) Some syscall reduction in APR on unix -- don't seek when setting
6095 up an mmap; and don't fcntl() more than once per socket.
6098 *) When mod_cgid is started as root, the cgi daemon now switches
6099 to the configured User/Group (like other httpd processes)
6100 instead of continuing as root. [Jeff Trawick]
6102 *) The prefork MPM now uses an APR lock for the accept() mutex.
6103 It has not been getting a lock at all recently. httpd -V now
6104 displays APR's selection of the lock mechanism instead of the
6105 symbols previously respected by prefork. [Jeff Trawick]
6107 *) Change the mmap() feature test to check only for existence.
6108 The previous check required features not used by Apache.
6111 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
6112 sometimes mangled. The len parm to accept() was not
6113 initialized, leading sometimes to an endless loop of failed
6114 accept() calls on OS/390 and anywhere else that failed the call
6115 if the len was negative. Use <sys/un.h> for struct sockaddr_un
6116 instead of declaring it ourselves to fix a compilation problem
6117 on Solaris. [Jeff Trawick]
6119 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
6121 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
6123 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
6125 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
6126 initialization if ALLOC_DEBUG is defined; no known symptom
6127 otherwise. [Jeff Trawick]
6129 *) Fix typo in configure script when checking for mod_so. bash
6130 doesn't seem to have a problem but /bin/sh on Solaris does.
6131 Symptom: "./configure: test: unknown operator =="
6134 *) Rebind the Win32 NT and 9x services control into the MPM.
6135 All console, WinNT SCM and Win9x pseudo-service control code is
6136 now wrapped within the WinNT MPM.
6139 *) Make a copy of getenv("PATH") before storing for later use. Some
6140 getenv() implementations use the same storage for successive calls.
6141 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
6143 *) Server Tokens work in 2.0 again. This also propogates the change
6144 to allow just the product name in the server string using
6148 Changes with Apache 2.0a4
6150 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
6151 won't need to call it. [Greg Ames, Jeff Trawick]
6153 *) Move pre_config hook call to between configuration read and config
6154 tree walk. This allows all modules to implement pre_config hooks
6155 and know that they will be called at an appropriate time.
6158 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
6161 *) Add pre-config hooks back to all modules.
6164 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
6165 ContentDigest enabled and we can't/don't mmap the file.
6168 *) We now report the correct line number for syntax errors in config
6169 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
6171 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
6172 related bugs, and changed shmem/locking to use apr API. Shared-mem
6173 is currently disabled, however, because of problems with graceful
6174 restarts. [Ronald Tschalär]
6176 *) Fix corruption of IFS variable in --with-module= handling.
6177 Depending on the user's shell or customization thereof, there
6178 would be errors generating ap_config_auto.h later in the configure
6179 procedure. [Jeff Trawick]
6181 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
6182 isn't used (as in 1.3), except that on Unix it is now logged via
6183 ap_log_rerror() instead of by the child having STDERR_FILENO refer
6184 to the error log. [Greg Ames, Jeff Trawick]
6186 *) Add '-D' argument processing for run time configuration defines.
6189 *) Organize http_main.c as independent code, such that no code or
6190 global data is exported from it. WIN32 will dynamically link it
6191 to the server core, so this will prevent mutual dependency.
6194 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
6195 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
6198 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
6199 [William Rowe, Jan Just Keijser <KEIJSERJJ logica.com>]
6201 *) Add mod_charset_lite for configuring character set translation.
6204 *) Add '-n' option to htpasswd to make it print its user:pw record
6205 on stdout rather than having to frob a text file. [Ken Coar]
6207 *) Fix saferead. Basically, we flush the output buffer if a read on the
6211 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
6212 a conversion is single-byte only. [Jeff Trawick]
6214 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
6215 the BeOS 5.0 documentation says that shutdown doesn't work yet.
6218 *) Fix some minor errors where pid was being manipulated as an int
6219 instead of the portable pid_t. [Roy Fielding]
6221 *) Fix some error log prints that were printing the pointer to a
6222 structure rather than the pid within the structure.
6223 [Jeff Trawick, Roy Fielding]
6225 *) ab: Fix a command-line processing bug; track bad headers in
6226 err_response; support reading headers up to 2K.
6227 [Ask Bjoern Hansen <ask valueclick.com>]
6229 *) Fix ap_resolve_env() so that it handles new function added in a prior
6230 alpha (see "Added the capability to do ${ENVVAR} constructs in the
6231 config file.") as well as the constructs used by mod_rewrite.
6232 [Paul Reder <rederpj raleigh.ibm.com>]
6234 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
6236 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
6237 APR to perform translation, instead of accessing the hard-coded tables
6238 in 1.3's ebcdic.c. [Jeff Trawick]
6240 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
6243 *) Add the ability to hook into the config file reading phase. Basically
6244 if a directive is specified EXEC_ON_READ, then when that directive is
6245 read from the config file, the assocaited function is executed. This
6246 should only be used for those directives that must muck with HOW the
6247 server INTERPRETS the config. This should not be used for directives
6248 that re-order or replace items in the config tree. Those changes should
6249 be made in the pre-config step.
6252 *) Add mod_example to the build system.
6255 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
6256 byte character sets. [Jeff Trawick]
6258 *) Pick up various EBCDIC fixes from 1.3 (from Martin
6259 Kraemer and Oliver Reh originally according to the change log).
6262 *) Fix a couple of problems in RFC1413 support (controlled by the
6263 IdentityCheck directive). Apache did not build the request string
6264 properly and more importantly Apache would loop forever if the
6265 would-be ident server dropped the connection before sending a
6266 properly terminated response. [Jeff Trawick]
6268 *) apxs works in 2.0.
6271 *) Reliable piped logs work in 2.0.
6274 *) Introduce a hash table implementation into APR to be used for
6275 replacing tables and other random data structures in Apache.
6278 *) Add some more error reporting to htpasswd in the case of problems
6279 generating or accessing the temporary file. Also, pass in a
6280 buffer if the implementation knows how to use it (i.e., if L_tmpnam
6281 is defined). [Ken Coar]
6283 *) Configure creates config.nice now containing your configure
6284 options. Syntax: ./config.nice [--more-options]
6287 *) Fix various return code problems in APR on Win32. For most of
6288 these, APR was returning APR_EEXIST instead of GetLastError()/
6289 WSAGetLastError(). [Jeff Trawick]
6291 *) Make piped logs work again in version 2.0
6294 *) Add VPATH support to UNIX build system of Apache and APR.
6297 *) Fix ap_tokenize_to_argv to respect the const arguments that are
6301 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
6302 Patch submitted to author.
6305 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
6306 /sbin in PATH on FreeBSD (all submitted to rse previously)
6309 *) Fix building Pthread-based MPMs on OpenBSD
6310 [Sascha Schumann] PR#26
6312 *) Fix ap_readdir() problem on systems where d_name[] field in
6313 struct dirent is declared with only one byte. (This problem only
6314 affected multithreaded builds.) This caused a segfault during
6315 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
6316 least). [Jeff Trawick]
6318 *) Fix some make-portability problems on at least Tru64, Irix
6320 [Sascha Schumann] PR#18, PR#39
6322 *) Add ap_sigwait() to support old-style sigwait() on systems
6323 like OS/390 and UnixWare.
6326 *) Add POSIX-thread flags for more platforms.
6329 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
6330 (on Unix, at least) to handle resolver errors. Fix a bug in
6331 the definition of APR_ENOMEM so that ap_strerror() can spit
6332 out the correct error message for it.
6335 Changes with Apache 2.0a3
6337 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
6340 *) API: *HOOK* macros now have an AP_ prefix
6343 *) Win32: Eliminate redundant calls to initialize winsock.
6344 [Tim Costello <timcostello ozemail.com.au>]
6346 *) Fix bugs initializing ungetchar for pipes.
6347 [Chia-liang Kao <clkao CirX.ORG>]
6349 *) The ab program in the src/support directory is now portable using
6353 *) Support directory is being compiled when the server is built
6356 *) The configure option --with-program-name has been added to allow
6357 developers to rename the executable at configure time. This also
6358 changes the name of the config files to match the executable's name.
6361 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
6362 containing version numbers. [Martin Pool]
6364 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
6365 Unix; access_log and error_log now created with these perms; non-
6366 Unix is unaffected [Jeff Trawick]
6368 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
6369 Replaced more magic numbers with MD5_DIGESTSIZE.
6370 [William Rowe, Roy Fielding]
6372 *) Win32: Get mod_auth_digest compiling and added to the Windows
6373 build environment. Not tested and I'd be suprised if it
6374 actually works. [Bill Stoddard]
6376 *) Revamp the Win32 make environment. Makefiles have been removed and
6377 Apache.dsw created to bring together all the pieces. Create new file
6378 os/win32/BaseAddr.ref to define module base addresses (to prevent
6379 dll relocation at start-up).
6380 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
6382 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
6383 of the \015, \012, and \015\012 constants with macros.
6386 *) Add ap_xlate_open() et al for translation of text between different
6387 character sets. The initial implementation requires iconv().
6390 *) More FAQs and answers from comp.infosystems.www.servers.unix.
6391 [Joshua Slive <slive finance.commerce.ubc.ca>]
6393 *) CGI output is being timed out now.
6396 *) Fix the problem with dieing quietly. dupfile now takes a pool which
6397 is used by the new apr file. There is no reason to create a new file
6398 with the same lifetime as the original file.
6401 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
6402 module base addresses. This will help shooting seg faults
6403 in the field. [William Rowe <wrowe lnd.com>]
6405 *) Update Apache on Windows documentation. Add new document
6406 describing how to compile Apache on Windows.
6407 [William Rowe <wrowe lnd.com>]
6409 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
6410 microseconds instead of seconds. Some storage leaks and other
6411 minor bugs in related code were fixed. [Jeff Trawick]
6413 *) Win32: First cut at getting mod_isapi working under 2.0
6414 [William Rowe <wrowe lnd.com>]
6416 *) First stab at getting mod_auth_digest working under 2.0
6417 quick change summary:
6418 - moved the random byte generation (ap_generate_random_bytes) into APR
6419 - now uses ap_time_t
6420 - compiles and runs on linux
6422 [Brian Martin <bmartin penguincomputing.com>]
6424 *) Win32: Move the space stripping of physical service names
6425 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
6426 unresolved symbol. Add dependency checking to the
6427 CreateService call to ensure TCPIP and AFP (winsock) is started
6429 [William Rowe <wrowe lnd.com>]
6431 *) Win32: Add code to perform latebinding on functions that may
6432 not exist on all levels of Windows where Apache runs. This
6433 is needed to allow Apache to start-up on Win95/98. All calls
6434 to non portable functions should be protected with
6435 ap_oslevel checks to prevent runtime segfaults.
6436 [William Rowe <wrowe lnd.com>]
6438 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
6440 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
6442 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
6443 This addresses PR 1623. Still need to address timing out runaway
6444 CGI scripts. [Bill Stoddard]
6446 *) Win32: Make ap_stat Windows 95/98 friendly
6447 [William Rowe <wrowe lnd.com>]
6449 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
6450 always fail. Need to initialise the dwOSVersionInfoSize member of the
6451 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
6454 The patch also enhances ap_get_oslevel (and the associated enum) to
6455 handle selected service packs for NT4, and adds recognition for
6456 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
6457 we can use ReadFileScatter and WriteFileGather in readwrite.c.
6458 [Tim Costello <Tim.Costello BTFinancialgroup.com>]
6460 *) Get mod_rewrite building and running, and mod_status building for Win NT
6461 [Allan Edwards <ake raleigh.ibm.com>]
6463 *) Patch to port mod_auth_db to the 2.0 api and also to support
6464 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
6465 2.7.7. It should work with version 1 as well but I haven't tested it.
6466 [Brian Martin <bmartin penguincomputing.com>]
6468 *) Get APR DSO code working under Windows. Includes cross platform
6470 [<Tim.Costello BTFinancialgroup.com>]
6472 *) Fix some of the Windows APR time functions.
6475 *) FAQ changes related to tidying up historical documents on the web site.
6476 [Joshua Slive <slive finance.commerce.ubc.ca>]
6478 *) Move Windows DSO code into APR.
6481 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
6482 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
6483 at build time. At this point, the server will not compile on Windows because
6484 of the recent DSO commits. Fixing those next.
6485 [Bill Rowe & Bill Stoddard]
6487 *) Added error checking for file I/O APR routines.
6488 [Jon Travis <jtravis covalent.net>]
6490 *) APR: Don't use the values of resolver error codes for the
6491 corresponding APR error codes. On Unix and Win32, return the
6492 proper APR error code after a resolver error. [Jeff Trawick]
6494 Changes with Apache 2.0a2
6496 *) Renamed the executable back to httpd on all platforms other
6500 *) Allow BeOS to survive restarts, log properly and a few
6501 small things it had problems with due to the way it setup
6502 users and groups. [David Reid]
6504 *) Get mod_rewrite working with APR locks
6505 [Paul Reder <rederpj raleigh.ibm.com>]
6507 *) Actually remove the sempahore when the lock cleanup routine
6508 is called on BeOS. [David Reid]
6510 *) Clear hook registrations between reads of the config file.
6511 When DSOs are unloaded and re-loaded the old hook pointers may
6512 no longer be valid. This fix eliminates potential segfaults.
6513 [Allan Edwards <ake raleigh.ibm.com>]
6515 *) Fix a problem with Sigfunc not being defined or bypassed
6516 if sigaction() wasn't found. [Jim Jagielski]
6518 *) Fix the locking mechanism on BSD variants. They now use fcntl
6519 locks. This allows the server to start and serve pages.
6522 *) First cut at getting the Win32 installer to work
6523 [William Rowe <wrowe lnd.com>]
6525 *) Get htpasswd compiling under Windows
6526 [William Rowe <wrowe lnd.com>]
6528 *) Change the log message for a bind() failure to show the
6529 interface and port number. [Jeff Trawick]
6531 *) Import the documentation from 1.3.12 and bring parts of it
6532 up-to-date with respect to the changes that have occurred
6536 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
6537 now logged correctly on BeOS.
6540 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
6541 Makefile.win includes the same user interface as the old
6543 [William Rowe <wrowe lnd.com>, Jeff Trawick <trawick us.ibm.com>]
6545 *) Win32 exec now uses COMSPEC environment string for command
6546 shell path resolution.
6547 [William Rowe <wrowe lnd.com>] PR#3715
6549 *) Win32: ap_connect() was not returning correct error condition
6551 [Allen Prescott <allen clanprescott.com>]
6553 *) Win32: ap_open() was broken on Win9x because an NT-specific
6554 flag was passed to CreateFile. ap_puts() added an unnecessary
6556 [Jeff Trawick <trawick us.ibm.com>]
6558 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
6559 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
6560 confusing ee/et name and made all extensions language/dialect
6561 rather than country reflecting. Changed example files to
6562 explicit reflect the ISO charset and added a few common
6563 ones to the example config [dirkx]
6565 *) Extend external module capability. To use this, you call
6566 configure with --with-module=path/to/mod1,path/to/mod2,etc.
6569 *) Backported the various "default charset" fixes from 1.3.12,
6570 including the AddDefaultCharset directive. [Jim Jagielski]
6572 *) Added the capability to do ${ENVVAR} constructs in the
6573 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
6574 it does this on a line by line basis; i.e. if the envvar
6575 expands to something with spaces you have to protect it
6576 by adding quotes around it (Unless of course you expect it
6577 to contains more than one argument. Alternatively you
6578 can compile it on a per token basis; which is what people
6579 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
6580 hampers fancier hacks.
6581 [Dirk-Willem van Gulik]
6583 *) Changed the 'ErrorDocument' syntax in that it NO longer
6584 supports the asymetric
6586 ErrorDocument 301 "Some message
6588 Note the opening " quote, without a closing quote. It now
6589 has either the following syntaxes
6591 ErrorDocument XXX /local/uri
6592 ErrorDocument XXX http://valid/url
6593 ErrorDocument XXX "Some Message"
6595 The recognition heuristic is: if it has a space it
6596 is a message. If it has no spaces and starts with a /
6597 or is a valid URL then treat it that way. Otherwise it
6598 is assumed to be a message.
6600 This breaks backward compatibility but makes live a hell
6601 of a lot easier for GUI's and config file parsers.
6602 [Dirk-Willem van Gulik]
6604 *) Changed 'CacheNegotiatedDocs' from its present/not-present
6605 syntax into a 'on' or 'off' syntax. As it currently is the
6606 only non nesting token which uses NO_ARGS and thus is an
6607 absolute pain for any config interface automation. This
6608 breaks backward compatibility. [Dirk-Willem van Gulik]
6610 *) Add ability to add external modules to the build process. This is
6611 done with --with-module=/path/to/module. Modules can only be added
6612 as static modules at this point.
6615 Changes with Apache 2.0a1
6617 *) Fix FreeBSD 3.3 core dump.
6618 Basically, ap_initialize() needs to get called before
6619 create_process(), since create_process() passes op_on structure
6620 to semop() to get a lock, but op_on isn't initialized until
6621 ap_initialize() calls setup_lock(). Here is a slight
6622 rearrangement to main() which calls ap_initialize() earlier...
6623 [Jeff Trawick <trawick us.ibm.com>]
6625 *) Enable Apache to use sendfile/TransmitFile API
6626 [Bill Stoddard, David Reid, Paul Reder]
6628 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
6632 *) Make file I/O and network I/O writev/sendv APIs consistent.
6633 Eliminate use of ap_iovec_t and use Posix struct iovec.
6634 Use seperate variable on ap_writev to set the number of iovecs
6635 passed in and number of bytes written.
6638 *) Adapt file iol to use APR functions. Replaced ap_open_file()
6639 with ap_create_file_iol(). ap_create_file_iol() requires that
6640 the file be opened prior to the call using ap_open().
6643 *) Port mod_include and mod_cgi to 2.0
6644 [Paul Reder, Bill Stoddard]
6646 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
6647 bytes_read/bytes_written is always valid (never -1). Plus
6648 some fixes to buff.c to correct problems introduced by the
6649 errno => ap_status_t changes a while back. Plus a fix to
6650 chunked encoding introduced right at the beginning of 2.0.
6653 *) Revamped UNIX build system to use autoconf and libtool.
6654 [Manoj Kasichainula, Sascha Schumann]
6656 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj raleigh.ibm.com>]
6658 *) SECURITY: More rigorous checking of Host: headers to fix security
6659 problems with mass name-based virtual hosting (whether using mod_rewrite
6660 or mod_vhost_alias).
6661 [Ben Hyde, Tony Finch]
6663 *) Add back support for UseCanonicalName in <Directory> containers.
6664 [Manoj Kasichainula]
6666 *) Added APLOG_STARTUP log type. This allows us to write an error
6667 message without any of the date and time information. As a part
6668 of this change, I also removed all of the calls to fprintf(stderr
6669 and replaced them with calls to ap_log_error using APLOG_STARTUP
6670 writing to stderr is no longer portable, because we don't direct
6671 stderr to the error log on all platforms.
6674 *) Convert error logging functions to take errno as an argument.
6675 This makes our error logs more portable, because some Windows API's
6676 don't set errno. This change allows us to still output a valid
6677 message on all of our platforms.
6680 *) mod_mime_magic runs in 2.0-dev now.
6681 [Paul Reder <rederpj raleigh.ibm.com>]
6683 *) sendfile has been added to APR.
6684 [John Zedlewski <zedlwski Princeton.EDU>]
6686 *) buff.c has been converted to no longer use errno.
6687 [Manoj Kasichainula]
6689 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
6690 interface adaption to APR functions did it. [Martin Kraemer]
6692 *) Support DSOs properly on 32-bit HP-UX 11.0
6693 [Dilip Khandekar <dilip cup.hp.com>]
6695 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
6696 [Ralf S. Engelschall]
6698 *) Cleaned APR build environment integration and bootstrap APR
6699 automatically for developers from src/Configure.
6700 [Ralf S. Engelschall]
6702 *) Fixed building of src/support/htpasswd.c
6703 [Ralf S. Engelschall]
6705 *) When generating the Location: header, mod_speling forgot
6706 to escape the spelling-fixed uri. (Forw-Port from 1.3)
6709 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
6711 *) Change all pools to APR contexts. This is the first step to
6712 incorporating APR into Apache. [Ryan Bloom]
6714 *) Move "handler not found" warning message to below the check
6715 for a wildcard handler. [Dirk <dirkm teleport.com>, Roy Fielding]
6716 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
6718 *) Support line-continuation feature in config.option file and
6719 allow the loading of multiple option sections at once via
6720 ``--with-option=<section1>,<section2>,...''
6721 [Ralf S. Engelschall]
6723 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
6725 Changes with Apache MPM
6727 *) Use asynchronous AcceptEx() and a completion port to accept and
6728 dispatch connections to threads in Windows NT/2000.
6731 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
6734 *) Implement the APACI --with-option facility
6735 (per default used the config.option file).
6736 [Ralf S. Engelschall]
6738 *) MPM BEOS port. [David Reid <abb37 dial.pipex.com>]
6740 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
6741 Replace pre_connection module call with a register_hook call and
6742 implement pre_connection as a hook. The intent is that these hooks will
6743 be extended to allow Apache to be multi-protocol, and also to allow the
6744 calling order to be specified on a per-hook/per-module basis.
6747 *) Implement mpm_* methods as "modules". Each method gets its own
6748 subdir in src/modules (eg: src/modules/prefork). Selection
6749 of method uses Rule MPM_METHOD. [Jim Jagielski]
6751 *) Port the hybrid server from the apache-apr repository as
6752 mpm_mpmt_pthread. [Manoj Kasichainula]
6754 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
6755 amongst the unix MPMs.
6757 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
6758 signal handling for the new world order. [Dean Gaudet]
6760 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
6761 of alloc.c for now. [Dean Gaudet]
6763 *) Handle partial large writes correctly. [Ben Laurie]
6765 *) Eliminate conn_rec's pointer to server. All it knows is the base server
6766 based on IP/port. [Ben Laurie]
6768 *) Port a bunch of modules to the new module structure.
6769 ["Michael H. Voase" <mvoase midcoast.com.au>]
6771 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
6773 *) Basic restructuring to introduce the MPM concept; includes various
6774 changes to the module API... better described by
6775 docs/initial_blurb.txt. [Dean Gaudet]
6777 Changes with Apache pthreads
6779 *) New buff option added: BO_TIMEOUT. It describes the timeout for
6780 buff operations (generally over a network).
6781 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
6783 *) Created http_accept abstraction. Added 4 new functions (not exported):
6784 init_accept(), begin_accepting_requests(), get_request(),
6785 stop_accepting_requests() [Bill Stoddard]
6787 *) Fix to ap_rprintf call that allows mod_info to work properly.
6788 [James Morris <jmorris intercode.com.au>]
6790 *) user and ap_auth_type fields were moved from connection_rec to
6791 request_rec. [Ryan Bloom]
6793 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
6794 needed in a threaded server.
6796 *) Initial pthread implementation from from Dean's apache-nspr code.
6797 [Bill Stoddard, Ryan Bloom]
6800 Changes with Apache 1.3.9
6802 *) Remove bogus error message when a redirect doesn't set Location.
6803 Instead, use an empty string to avoid coredump if the error message
6804 was supposed to include a location. [Roy Fielding]
6806 *) Don't allow configure to include mod_auth_digest unless it is
6807 explicitly requested, even if the user asked for all modules.
6810 *) Translate module names to dll names for OS/2 so that they are no more
6811 than 8 characters long and have an extension of "dll" instead of "so".
6814 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
6815 Fix test-compile check to check for randbyte instead of trand32.
6816 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
6817 and tweak to make Amaya happier. [Ronald Tschalär]
6819 *) Ensure that the installed expat include files are world readable,
6820 just like the other header files. [Martin Kraemer]
6822 *) Fixed generated AddModule adjustments in APACI's `configure' script
6823 in order to allow (new) modules like mod_vhost_alias to be handled
6824 correctly (which was touched by the adjustments for mod_alias).
6825 [Ralf S. Engelschall]
6827 *) For binary builds, add -R flag to apachectl to work around the lack of
6828 an absolute path to the ./libexec directory where the libhttp.ep file
6829 is needed for SHARED_CORE architectures. [Randy Terbush]
6831 *) WIN32: Create the CGI script process as DETACHED. This may solve the
6832 problem observed by some Win95/98 users where they get CGI script
6833 output sent to the console. [Bill Stoddard]
6835 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
6836 routines are now called ap_base64* and are 'plain' (i.e., no
6837 pool access or anything clever). Inside util.c the routines acting
6838 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
6839 The oddly named ap_uuencode(), ap_uudecode() are kept around for
6840 now but deprecated. [dirkx]
6842 *) Clean up the base64 and SHA1 additions and make sure they are
6843 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
6844 files. [Roy Fielding]
6846 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
6847 checking. Allow compiling on VS 6.0. [Randy Terbush]
6849 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
6851 *) Use TestCompile to search for the truerand library (rather than blindly
6852 assuming its existence). If it is not found, complain (but do not
6853 exit - yet). [Martin Kraemer]
6855 *) We forgot to add the new exported function names to
6856 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
6858 *) Add description of -T command-line option to usage().
6859 [Ralf S. Engelschall]
6861 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
6862 searched only AFTER libap has been searched, because libap needs
6863 some symbols from libos. [Martin Kraemer]
6865 *) Fix conflict with original mod_digest related to the symbol of the
6866 module dispatch list (which has to be unique for DSO and follow the
6867 usual conventions for the installation procedure).
6868 [Ralf S. Engelschall]
6870 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
6871 for other platforms as well. [Martin Kraemer]
6873 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
6874 types by AP_LONG and replace reference to renamed variable 'ubuf'
6875 by 'buffer'. [Martin Kraemer]
6877 Changes with Apache 1.3.8 [not released]
6879 *) Flush the output buffer immediately after sending an error or redirect
6880 response, since the result may be needed by the client to abort a
6881 long data transfer or restart a series of pipelined requests.
6882 [Tom Vaughan <tvaughan aventail.com>, Roy Fielding]
6884 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
6885 [Ian Turner <iant sequent.com>] PR#4735
6887 *) Local struct mmap in http_core.c conflicted with system structure
6888 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
6890 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
6891 [Ronald Tschalär <ronald innovation.ch>]
6893 *) Fix a memory leak where the module counts were getting messed
6894 up across restarts. [David Harris <dharris drh.net>]
6896 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
6897 properly in mod_access.
6898 ["Paul J. Reder" <rederpj raleigh.ibm.com>] PR#4770
6900 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
6901 [Dmitry Khrustalev <dima bog.msu.su>] PR#3874
6903 *) PORT: Support for compaq/tandem/com.
6904 [Michael Ottati <michael.ottati compaq.com>, dirkx]
6906 *) Added SHA1 password encryption support to easy migration from
6907 Netscape servers. See support/SHA1 for more information.
6908 Caused the separation of ap_md5.c into md5, sha1 and a general
6909 ap_checkpass.c with just a validate_passwd routine. Added a
6910 couple of flags to support/htpasswd. Some reuse of the to64()
6911 function; hence renamed to ap_to64().
6912 [Dirk-Willem van Gulik, Clinton Wong <clintdw netcom.com>]
6914 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
6915 with ASCII/EBCDIC conversions in "ident" query.
6916 [David McCreedy <McCreedy us.ibm.com>]
6918 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
6919 Change "Power Macintosh" to Power* so if uname prints "Power Book"
6920 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
6922 *) Fix SIGSEGV on some systems because the Vary fix below included
6923 a call to table_do with a variable argument list that was not
6924 NULL terminated. Replaced with better implementation. [Roy Fielding]
6926 Changes with Apache 1.3.7 [not released]
6928 *) The "Vary" response header field is now sanitised right before
6929 the header is sent back to the client. Multiple "Vary" fields
6930 are combined, and duplicate tokens (e.g., "Vary: host, host" or
6931 "Vary: host, negotiate, host, accept-language") are reduced to
6932 single instances. This is a better solution than the force-no-vary
6933 one (which is still valid for clients that can't cope with Vary
6934 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
6936 *) Portability changes for BeOS. [David Reid <abb37 dial.pipex.com>]
6938 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
6939 least on Linux and FreeBSD for now.
6942 *) Win32: More apache -k restart work. Restarts are now honored
6943 immediately and connections in the listen queue are -not- lost.
6944 This is made possible by the use of the WSADuplicateSocket()
6945 call. The listeners are opened in the parent, duplicated, then
6946 the duplicates are passed to the child. The original listen sockets
6947 are not closed by the parent across a restart, thus the listen queue
6949 [Bill Stoddard <stoddard raleigh.ibm.com>]
6951 *) Fix handling of case when a client has sent "Expect: 100-continue"
6952 and we are going to respond with an error, but get stuck waiting to
6953 discard the body in the pointless hope of preserving the connection.
6954 [Roy Fielding, Joe Orton <jeo101 york.ac.uk>] PR#4499, PR#3806
6956 *) Fix 'configure' to work correctly with SysV-based versions of
6957 'tr' (consistent with Configure's use as well). [Jim Jagielski]
6959 *) apxs: Add "-S var=val" option which allows for override of CFG_*
6960 built-in values. Add "-e" option which works like -i but doesn't
6961 install the DSO; useful for editing httpd.conf with apxs. Fix
6962 editing code so that multiple invocations of apxs -a will not
6963 create duplicate LoadModule/AddModule entries; apxs can now be
6964 used to re- enable/disable a module. [Wilfredo Sanchez]
6966 *) Win32: Update the server to use Winsock 2. Specifically, link with
6967 ws2_32.lib rather than wsock32.lib. This gives us access to
6968 WSADuplcateSocket() in addition to some other enhanced comm APIs.
6969 Win 95 users may need to update their TCP/IP stack to pick up
6970 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
6971 [Bill Stoddard <stoddard raleigh.ibm.com>]
6973 *) Win32: Redirect CGI script stderr (script debug info) into the
6974 error.log when CGI scripts fail. This makes Apache on Win32
6975 behave more like Unix.
6976 [Bill Stoddard <stoddard raleigh.ibm.com>]
6978 *) Fixed `httpd' usage display: -D was missing.
6979 [Ralf S. Engelschall] PR#4614
6981 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
6982 [Ralf S. Engelschall] PR#4561, PR#4562
6984 *) OS/2: Fix problem with accept lock semaphores where server would die with
6985 "OS2SEM: Error 105 getting accept lock. Exiting!"
6986 [Brian Havard] PR#4505
6988 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
6989 [Randy Terbush <randy covalent.net>]
6991 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
6992 used by Demon Internet, Ltd. [Tony Finch <fanf demon.net>]
6994 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
6995 command potentially _is_ GCC. [Ralf S. Engelschall]
6997 *) Fix apxs build issues on AIX
6998 [Rasmus Lerdorf <rasmus raleigh.ibm.com>]
7000 *) DocumentRoot Checking: Under previous versions, when Apache
7001 first started up, it used to do a stat of each DocumentRoot to
7002 see if it existed and was a directory. If not, then an error
7003 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
7004 does not exist, you will get error messages in error_log. If
7005 the '-t' command line option is used (to check the configuration)
7006 the check of DocumentRoot IS performed. An additional command
7007 line option, '-T', has been added if you want to avoid the
7008 DocumentRoot check even when checking the configuration.
7011 *) Win32: The query switch "apache -S" didn't exit after showing the
7012 vhost settings. That was inconsistent with the other query functions.
7013 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
7015 *) Win32: Changed behaviour of apache -k restart.
7016 Previously, the server would drain all connections in the stack's
7017 listen queue before honoring the restart. On a busy server, this
7018 could take hours. Now, a restart is honored almost immediately.
7019 All connections in Apache's queues are handled but connections in
7020 the stack's listen queue are discarded. Restart triggered by
7021 MaxRequestPerChild is unchanged.
7022 [Bill Stoddard <stoddard raleigh.ibm.com>]
7024 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
7025 the accept loop. Good for a 5% performance boost. Cleaned up
7026 parent/child process management code.
7027 [Bill Stoddard <stoddard raleigh.ibm.com>]
7029 *) Added ceiling on file size for memory mapped files.
7030 [John Giannandrea <jg meer.net>] PR#4122
7032 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
7033 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
7034 [Henri Gomez <gomez slib.fr>, Ralf S. Engelschall]
7036 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
7037 use this at least for Expat. [Ralf S. Engelschall]
7039 *) Allow .module files to specify libraries with Lib:.
7042 *) Allow SetEnvIf[NoCase] to test environment variables as well
7043 as header fields and request attributes. [Ken Coar]
7045 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
7046 content-types are "text/html;parameters". PR#4524 [Ken Coar]
7048 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
7049 never accepted into any standard, and it opens up certain DoS
7050 attacks. [Koen Holtman <Koen.Holtman cern.ch>]
7052 *) TestCompile updated. We can now run programs and output the
7053 results during the Configure process. [ Jim Jagielski]
7055 *) The source is now quad (long long) aware as needed. Specifically,
7056 the Configure process determines the correct size of off_t and
7057 *void. When the OS/platform/compiler supports quads, ap_snprintf()
7058 provides for the 'q' format qualifier (if quads are not available,
7059 'q' is silently "demoted" to long). [Jim Jagielski]
7061 *) When the username or password fed to htpasswd is too long, include the
7062 size limit in the error message. Also report illegal characters
7063 (currently only ':') in the username. Add the size restrictions
7064 to the man page. [Ken Coar]
7066 *) Fixed the configure --without-support option so it doesn't result in
7067 an infinite loop. [Marc Slemko]
7069 *) Piped error logs could cause a segfault if an error occured
7070 during configuration after a restart.
7071 [Aidan Cully <aidan panix.com>] PR#4456
7073 *) If a "Location" field was stored in r->err_headers_out rather
7074 than r->headers_out, redirect processing wouldn't find it and
7075 the server would core dump on ap_escape_html(NULL). Check both
7076 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
7077 if Location isn't set. [Doug MacEachern, Ken Coar]
7079 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
7080 of the Expat 1.0.2 distribution. [Greg Stein]
7082 *) Replace regexec() calls with calls to a new API stub function
7083 ap_regexec(). This solves problems with DSO modules which use the regex
7084 library. [Jens-Uwe Mager <jum helios.de>, Ralf S. Engelschall]
7086 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
7087 environment variables can be set according to the protocol version
7088 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
7090 *) Add DSO support for OpenStep (Mach 4.2) platform.
7091 [Ralf S. Engelschall, Rex Dieter <rdieter math.unl.edu>] PR#3997
7093 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
7094 [Jan Gallo <gallo pvt.sk>] PR#3690, PR#4373
7096 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
7097 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
7099 *) Better DSO flags recognition on NetBSD platforms using ELF.
7100 [Todd Vierling <tv pobox.com>] PR#4310
7102 *) Always log months in english format for %t in mod_log_config.
7103 [Petr Lampa <lampa fee.vutbr.cz>] PR#4366, 679
7105 *) Support for server-parsed and multiview-determined ReadmeName and
7106 HeaderName files in mod_autoindex. Removed the restriction on
7107 "/"s in ReadmeName and HeaderName directives since the *sub_req*
7108 routines will deal with the access issues. (It's now possible to
7109 have {site|group|project|customer|...} wide readmes and headers.)
7110 [Raymond S Brand <rsbx rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
7113 *) When stat() fails, don't assume anything about the contents of
7114 the struct stat. [Ed Korthof <ed bitmechanic.com>]
7116 *) It's OK for a semop to return EINTR, just loop around and try
7117 again. [Dean Gaudet]
7119 *) Fix configuration engine re-entrant hangups, which solve a
7120 handful of problems seen with mod_perl <Perl> configuration sections
7121 [Salvador Ortiz Garcia <sog msg.com.mx>]
7123 *) Mac OS and Mac OS X Server now use the appropriate custom layout
7124 by default when building with APACI; allow for platform-specific
7125 variable defaults in configure. [Wilfredo Sanchez]
7127 *) Do setgid() before initgroups() in http_main; some platforms
7128 zap the grouplist when setgid() is called. This was fixed in
7129 suexec earlier, but the main httpd code missed the change.
7130 [Rob Saccoccio <robs InfiniteTechnology.com>] PR#2579
7132 *) Add recognition of .tgz as a gzipped tarchive.
7133 [Bertrand de Singly <bertrand.de-singly polytechnique.fr>] PR#2364
7135 *) mod_include's fsize/flastmod should allow only relative paths, just
7136 like "include file". [Jaroslav Benkovsky <benkovsk pha.pvt.cz>]
7138 *) OS/2: Add support for building loadable modules using DLLs.
7141 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
7144 *) Fix minor but annoying bug with the test for Configuration.tmpl
7145 being newer than Configuration so that it is less likely to fail
7146 when using APACI and shadow sources. [Wilfredo Sanchez]
7148 *) PORT: Add initial support for Mac OS (versions 10.0 and
7149 greater). Use Mac OS X Server layout for now. Clean up dyld code
7150 in unix/os.c, and don't install the dyld error handlers, which
7151 are no longer needed in Mac OS. [Wilfredo Sanchez]
7153 *) Rename Rhapsody layout to "Mac OS X Server". Change install
7154 locations to appropriate ones for user-built (as opposed to
7155 system) installs. [Wilfredo Sanchez]
7157 *) Modify mod_autoindex's handling of AddDescription so that the
7158 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
7160 *) Add functionality to the install-bindist.sh script created by
7161 binbuild.sh to use tar when copying distribution files to the
7162 serverroot. This allows upgrading an existing installation
7163 without nesting the new distribution in the old.
7165 install-bindist.sh now detects the local perl5 path to install
7166 apxs and dbmmanage with proper path to perl interpreter.
7168 Add an install-binsupport target which copies the source files
7169 for apxs and dbmmanage to bindist to allow these scripts to
7170 be properly installed relative to the destination serverroot.
7171 [Randy Terbush, Covalent Technologies, <randy covalent.net>]

7185 *) Force the LANG envariable to the known state of "C" so that we
7186 have assurance about how string manipulators (e.g., tr) will
7187 function. [Ken Coar] PR#1630
7189 *) Add a directive to allow customising of the tracking cookie name.
7190 [Ken Coar] PR#2921, 4303
7192 *) Add "force-no-vary" envariable to allow servers to work around
7193 clients that choke on "Vary" fields in the response header.
7194 [Ken Coar, Dmitry Khrustalev <dima zippy.machaon.ru>] PR#4118
7196 *) Fixed a bug in mod_dir that causes a child process will infinitely
7197 recurse when it attemps to handle a request for a directory wnd the
7198 value of the DirectoryIndex directive is a single dot. Also likely
7199 to happen for anyother values of DirectoryIndex that will map back

7292 a) the htdigest utility overwrote the old contents of the digest file
7293 b) the Content-MD5 header value (ContentDigest directive) was wrong

7331 [Keith Wannamaker, Ken Parzygnat, Bill Stoddard]
7333 *) Correct the signed/unsigned character handling for the MD5 routines;
7334 mismatches were causing compilation problems with gcc -pedantic and
7335 in the TPF cross-compilation. [Ken Coar]
7337 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
7338 a roughly 5 fold speed up. [Brian Havard]
7340 *) proxy ftp: instead of using the hardwired string "text/plain" as
7341 a fallback type for files served by the ftp proxy, use the
7342 ap_default_type() function to determine the configured type.
7343 This allows for special configurations like
7344 <Directory proxy:ftp://some.host>
7345 DefaultType gargle/blurb
7347 Additionally, add the Content-Encoding: header to FTP proxy replies
7348 when the encoding is defined (by the AddEncoding directive).
7349 Because it was missing, it was almost impossible to browse compressed
7350 files using the FTP proxy (works now perfectly in Communicator).
7351 The ftp proxy now also returns the Date: and Server: header lines (if not
7352 much else... This code is "somewhat" broken) like normal requests do.
7355 *) Be more smart in APACI's configure script when determining the UID/GID
7356 for User/Group directives and use the determined UID/GID to initialize
7357 the permissions on the proxycachedir.
7358 [Dirk-Willem van Gulik, Ralf S. Engelschall]
7360 *) Changed the forking-prior-to-cleanup in the proxy module to first
7361 check wether it actually needs to collect garbage. This reduces
7362 the number of fork()s from one/request to just the odd one an hour.
7363 [Dirk-Willem van Gulik]
7365 *) Added proxy, auth and header support to src/support/ab.c. Added a
7366 README file to src/support/

7369 *) Don't hard-code the path to AWK in --shadow bootstrapping Makefile.
7370 [Ralf S. Engelschall] PR#4050
7372 *) Add support for DSO module compilation on BSD/OS 3.x.
7373 [Randy Terbush, Covalent Technologies]
7375 *) Fix sed-substitutions in `make install': path elements like `httpd/conf'
7376 (for instance from an APACI configure --sysconfdir=/etc/httpd/conf
7377 option) were substituted with $(TARGET).conf, etc. Same for other strings
7378 with dots where the dot wasn't matched as plain text.
7379 [Ralf S. Engelschall]
7381 *) PORT: Add support for FreeBSD 4.x [Ralf S. Engelschall]
7383 *) Fix verbose output of APACI configure (option -v)

7386 Changes with Apache 1.3.6
7388 *) Removed new PassAllEnv code due to DSO problems. [Lars Eilebrecht]
7390 Changes with Apache 1.3.5 [not released]
7392 *) M_INVALID needed a value within the scope of METHODS so that unknown
7393 methods can be access controlled. [Roy Fielding] PR#3821
7395 *) Added PassAllEnv; makes server's entire environment available
7396 to CGIs and SSIs executed within directive's scope. [Ken Coar]
7398 *) ap_uuencode() always added two trailing '='s and encoding of
7399 8 bit characters on a machine with signed char may produced
7400 incorrect results. Additionally ap_uuencode() should now
7401 work correctly on EBCDIC platforms.
7402 [Ronald Tschalär <ronald innovation.ch>] PR#3411
7404 *) WIN32: Binary installer now runs the configuration DLL before
7405 the reboot prompt (which is only given if MSVCRT.DLL system
7406 DLL is new or updated). This should avoid the configuration
7407 directory being empty after installation. [Paul Sutton]
7408 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988
7410 *) WIN32: Binary installer now creates Start menu options to start
7411 and stop Apache as a console application and to uninstall
7412 the Apache service on NT. [Paul Sutton] PR#3741
7414 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
7416 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
7417 have been reported with flock() locking (probably related to kernel
7418 version). [Dean Gaudet] PR#2723, 3531
7420 *) Using APACI, the main config file (usually httpd.conf) was
7421 not being adjusted as $(TARGET).conf. [Wilfredo Sanchez
7422 <wsanchez apple.com>]
7424 *) PORT: AIX does not require the SHARED_CODE "hack"
7425 [Ryan Bloom <rbb raleigh.ibm.com>]
7427 *) Set-Cookie headers were being doubled up for some CGIs by the O(n^2)
7428 avoidance code added in 1.3.3.
7429 [Dean Gaudet, Jeff Lewis <lewis stanford.edu>] PR#3872
7431 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
7432 for 8-bit safeness. [Dean Gaudet]
7434 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
7435 because SPARCs have a small machine-specific maximum size for the Global
7436 Offset Table which is often exceeded when compiling one of the larger
7437 third-party modules with Apache. [Peter Urban <Peter.Urban epfl.ch>] PR#3977
7439 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the
7440 DSO/DLL section because it's a directive from mod_status and isn't
7441 available before the DLL of mod_status is loaded.
7442 [Martin POESCHL <mpoeschl gmx.net>] PR#3936
7444 *) SECURITY: Fix a bug in the calculation of the buffer size for the line
7445 continuation facility in Apache's configuration files which could
7446 lead to a buffer overflow situation.
7447 [Thomas Devanneaux <Thomas.Devanneaux enst.fr>] PR#3617
7449 *) Make documentation and error messages of APACI's --activate-module=FILE
7450 option more clear. [Jan Wolter <janc wwnet.net>] PR#3995

7453 really support all future gcc versions >= 2.7 until we know more.
7454 [John Tobey <jtobey banta-im.com>] PR#3983
7456 *) Let APACI's configure script correctly complain for unknown --enable-XXX
7457 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
7459 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
7460 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
7461 possible buffer overflows. [Ralf S. Engelschall]
7463 *) Remove no longer used non-API function ap_single_module_init().
7464 [Ralf S. Engelschall]
7466 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
7469 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
7470 to make platform installations easier. [Wilfredo Sanchez]
7472 *) In configure, do not append the target name to the directory path if
7473 the path already contains "apache". [Ralf S. Engelschall]
7475 *) SIGPIPE is now ignored by the server core. The request write routines
7476 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
7477 correctly check for output errors and mark the connection as aborted.
7478 Replaced many direct (unchecked) calls to ap_b* routines with the
7479 analogous ap_r* calls. [Roy Fielding]
7481 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
7482 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
7483 Furthermore map lookups for non-existent keys are now cached as well.
7484 Additionally "txt" maps are now parsed with simple string functions
7485 instead of using ap_pregcomp(). As a side effect a bug that prevented
7486 the usage of keys containing the "," character was fixed.
7487 The changes drastically improve the performance when large rewrite maps
7489 [Michael van Elst <mlelstv serpens.swb.de>, Lars Eilebrecht] PR#3160
7491 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
7492 other than GET, and const'd the definition of method in request_rec.
7495 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
7497 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
7498 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
7500 *) Add %V to mod_log_config, this logs the hostname according to the
7501 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
7502 %v). Useful for mass vhosting. [Tony Finch <dot dotat.at>]
7504 *) Add support for \n and \t to mod_log_config, can be used to produce
7505 more reliable logs with multiline entries. [Tony Finch <dot dotat.at>]
7507 *) Fixed a few compiler nits. [John Bley <jbb6 acpub.duke.edu>]
7509 *) Added informative error messages for failed munmap() and fseek() calls
7510 in http_core.c. [John Bley, Roy Fielding]
7512 *) Added some informative error messages for some failed malloc()
7513 calls. [John Bley <jbb6 acpub.duke.edu>, Jim Jagielski]
7515 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
7516 is removed. This allows <Directory proxy:*> directives to work and
7517 prevents invalid requests from killing the process.
7518 [Brian Havard <brianh kheldar.apana.org.au>]
7520 *) Reorganised FAQ document.
7521 [Joshua Slive <slive finance.commerce.ubc.ca>] PR#2497
7523 *) src/support/: The ApacheBench benchmark program was overhauled by
7524 David N. Welton: you can now have it generate an HTML TABLE, presumably
7525 for integration into other HTML sources. David updated the ab man page
7526 as well and added some missing descriptions. Thanks!
7527 [David N. Welton <davidw prosa.it>]
7529 *) Win32: The filename validity checker now allows filenames containing
7530 characters in the range 0x80 to 0xff (for example accented characters).
7531 [Paul Sutton] PR#3890
7533 *) Added conditional logging based upon environment variables to
7534 mod_log_config. mod_log_referer and mod_log_agent
7535 are now deprecated. [Ken Coar]
7537 *) Allow apache acting as a proxy server to relay the real
7538 reason of a failure to a client rather than the "internal
7539 server error" it does currently. The general exposure mechanism
7540 can be triggered by any module by setting the "verbose-error-to"
7541 note to "*"; this allows more than just proxy errors to be exposed.
7542 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
7544 *) Moved man pages for ab and apachectrl to section 8.
7545 [Wilfredo Sanchez, Roy Fielding]
7547 *) Added -S option to install.sh so that options can be passed to
7548 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
7550 *) Tweak modules Makefile generated by Configure so that it handles
7551 the test case of no modules being selected. [<chaz reliant.com>]
7553 *) Added a <LimitExcept method ...> sectioning directive that allows
7554 the user to assign authentication control to any HTTP method that
7555 is *not* given in the argument list; i.e., the logical negation
7556 of the <Limit> directive. This is particularly useful for controlling
7557 access on methods unknown to the Apache core, but perhaps known by
7558 some module or CGI script. [Roy Fielding, Tony Finch]
7560 *) Prevent apachectl from complaining if the PIDFILE exists but
7561 does not contain a process id, as might occur if the server is
7562 being rapidly restarted. [Wilfredo Sanchez]
7564 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
7566 *) Entity tag comparisons for If-Match and If-None-Match were not being
7567 performed correctly -- weak tags might cause false positives. Also,
7568 strong comparison wasn't properly enforced in all cases.
7569 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
7571 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
7574 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
7575 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
7577 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
7578 to util.c for parsing an HTTP header field value to extract the next
7579 list item, taking into account the possible presence of nested comments,
7580 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
7581 insignificant whitespace and lowercases non-quoted tokens.
7582 [Roy Fielding] PR#2065
7584 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
7585 code different from 500. This allows the proxy to, e.g., return
7586 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
7588 *) Fix ordering of language variants for the case where the traditional
7589 negotiation algorithm is being used with multiple language variants
7590 and no Accept-Language. [James Treacy <treacy debian.org>] PR#3299, 3688
7592 *) Do not round the TCN quality calculation to 5 decimal places,
7593 unlike RFC 2296, because the calculation might need 12 decimal places
7594 to get the right result. [Roy Fielding]
7596 *) Remove unused code to disable transparent negotiation when
7597 negotiating on encoding only, as we now handle encoding too
7598 (though this is nonstandard for TCN), remove charset=ISO-8859-1
7599 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
7600 some debugging statements within mod_negotiation. [Koen Holtman]
7602 *) Fixed a rare memory corruption possibility in mod_dir if the index
7603 file is negotiable and no acceptable variant can be found.
7604 [Dean Gaudet, Roy Fielding, Martin Kraemer]
7606 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
7607 searching the Win32 registry for script interpreters.
7610 *) Win32: The compiled-in default filename for the error log is now
7611 error.log, which matches the default in the distributed httpd.conf.
7614 *) Win32: Any error messages from -i or -u command line options are now
7615 displayed on the console output rather than sent to the error log.
7616 Also the "Running Apache..." message is not output unless Apache is
7617 going to serve requests. [Paul Sutton]
7619 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
7620 and use a private significator ('$apr1$') to mark passwords as
7621 being smashed with our own algorithm. Also abstract the password
7622 checking into a new ap_validate_password() routine. [Ken Coar]
7624 *) Win32: The filename validity checker now allows "COM" but refuses
7625 access to "COM1" through "COM4". This allows filenames such
7626 as "com.name" to be served. [Paul Sutton] PR#3769.
7628 *) BS2000: Adapt to the new ufork() system call interface which will
7629 make subtasking easier on the OSD/POSIX mainframe environment.
7632 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
7633 ap_compat.h. [David White <david persimmon.com>] PR#3725
7635 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
7636 use `.db' instead of `.pag' not only for FreeBSD, but also when
7637 the NDBM library looks like Berkeley-DB based.
7638 [Ralf S. Engelschall] PR#3773
7640 *) Add ability to handle DES or MD5 authentication passwords.
7641 [Ryan Bloom <rbb Raleigh.IBM.Com>]
7643 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
7645 *) SECURITY: Avoid some buffer overflow problems when escaping
7646 quoted strings. (This overflow was on the heap and we believe
7647 impossible to exploit.) [Rick Perry <perry ece.vill.edu>]
7649 *) Let src/Configure be aware of CFLAGS options starting with plus
7650 signs as it's the case for the HP/UX compiler.
7651 [Doug Yatcilla <yatcilda umdnj.edu>] PR#3681
7653 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
7654 and check to see if the tar we wind up with supports '-h'.
7655 [Jim Jagielski] PR#3671
7657 *) A consistent and conservative style for all shell scripts has been
7658 implemented. Basically, all shell string tests use the traditional
7659 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
7660 to protect against bare null variable strings (ie: wrapping both
7661 sides with double quotes and prepending 'x'). 'x' was chosen
7662 because it's more universal and hopefully easier for old shell
7663 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
7666 *) The status module now prints out both the main server generation as
7667 well as the generation of each process. Also, the vhost info is
7668 printed with '?notable'. [Jim Jagielski]
7670 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
7671 and this makes its functions available to things in src/support.
7674 Changes with Apache 1.3.4
7676 *) Renamed macros status_drops_connection to ap_status_drops_connection
7677 and vestigial scan_script_header to ap_scan_script_header_err,
7678 mostly for aesthetic reasons. [Roy Fielding]
7680 *) The query switch "httpd -S" didn't exit after showing the
7681 vhost settings. That was inconsistent with the other query functions.
7684 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
7685 filename to the end of the STANDARD_MODULE_STUFF. Its
7686 presence at the beginning prevented reporting of the filename
7687 for modules compiled before 1 January 1999. [Ken Coar]
7689 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
7690 to detect and prevent access to special DOS device file names.
7691 [Paul Sutton, Ken Parzygnat]
7693 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
7694 and Makefile_win32_debug.txt (debug build) that work on Win95.
7695 Run each of the following from the src directory:
7696 nmake /f Makefile_win32.txt # compiles normal build
7697 nmake /f Makefile_win32.txt install # compiles and installs
7698 nmake /f Makefile_win32.txt clean # removes compiled junk
7699 nmake /f Makefile_win32_debug.txt # compiles debug build
7700 nmake /f Makefile_win32_debug.txt install
7701 nmake /f Makefile_win32_debug.txt clean
7704 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
7705 to build binary distributions. [Lars Eilebrecht]
7707 *) IndexOptions SuppressColumnSorting only turned off making
7708 the column headers anchors; you could still change the display
7709 order by manually adding a '?N=A' or similar query string to the
7710 URL. Now SuppressColumnSorting locks in the sort order so
7711 it can't be overridden this way. [Ken Coar]
7713 *) Added IndexOrderDefault directive to supply a default sort order
7714 for FancyIndexed directory listings. [Ken Coar] PR#1699
7716 *) Change the ap_assert macro to a variant that works on all platforms.
7717 [Richard Prinz <richard.prinz cso.net>] PR#2575
7719 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
7720 search for an underscore on dlsym() (as it's already the case
7721 for FreeBSD 3.0). [Todd Vierling <tv pobox.com>] PR#2462
7723 *) Small fix for mod_env.html: The module was documented as to be _not_
7724 compiled into Apache per default, although it _IS_ compiled into
7725 Apache per default. [Sim Harbert <sim mindspring.com>] PR#3572
7727 *) Instead of fixing a bug in the generation procedure for config.status (a
7728 backslash was missing) we remove the bug together with it's complete
7729 context because the special cases of the past can now no longer occur
7730 because of the recent magic for the --with-layout default.
7731 [Ralf S. Engelschall] PR#3590
7733 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
7734 making sure the src/support/ tools are _forced_ to be build last (they
7735 depend on other libraries).
7736 [Markus Theissinger <markus.theissinger gmx.de>]
7738 *) Fix installation procedure: Now that os-inline.c is actually used (a
7739 recently fixed bug prevented this) we need to also install os-include.c
7740 in addition to os.h into the PREFIX/include/ location or building of
7741 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
7743 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
7744 allow us to distinguish between a garbled DSO (or even a file which isn't
7745 an Apache module DSO at all) and a DSO which doesn't match the current
7746 Apache API. [Ralf S. Engelschall] PR#3152
7748 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
7749 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
7750 match case insensitive (this especially avoids nasty patterns like
7751 `[tT][eE][sS][tT]'). Second two additional internal map functions
7752 `escape' and `unescape' were added which can be used to escape/unescape
7753 to/from hex-encodings in URLs parts (this is especially useful in
7754 combination with map lookups).
7755 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
7757 *) Renamed the macro escape_uri() to ap_escape_uri() which was
7758 forgotten (because it was a macro) in the symbol renaming process.
7759 [Ralf S. Engelschall]
7761 *) Fix some inconsistencies related to the scopes of directives. The only
7762 user visible change is that the directives `UseCanonicalName' and
7763 `ContentDigest' now use the (more correct) `Options' scope instead of
7764 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
7766 *) Using DSO, the Server token was being mangled. Specifically, the
7767 module's token was being added first before the Apache token. This
7768 has been fixed. [Jim Jagielski]
7770 *) Major overhaul of mod_negotiation.c, part 2.
7771 - properly handle "identity" within Accept-Encoding.
7772 - allow encoded variants in RVSA negotiation and let them appear in
7773 the Alternates field using the non-standard "encoding" tag-list.
7774 - fixed both negotiation algorithms so that an explicitly accepted
7775 encoding is preferred over no encoding if "identity" is not
7776 included within Accept-Encoding.
7777 - added ap_array_pstrcat() to alloc.c for efficient concatenation
7778 of large substring sequences.
7779 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
7782 *) Major overhaul of mod_negotiation.c, part 1.
7783 - cleanups to mod_negotiation comments and code structure
7784 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
7785 support for everything in the upcoming HTTP/1.1
7786 revision (draft-ietf-http-v11-spec-rev-06.txt).
7787 - language tag matching also handles tags with more than 2
7789 - empty Accept, Accept-Language, Accept-Charset headers are
7790 processed correctly; previously an empty header would make all
7791 values acceptable instead of unacceptable.
7792 - allowed for q values in Accept-Encoding
7793 - added support for transparent content negotiation (rfc2295 and
7794 rfc2296) (though we do not implement all features in these drafts,
7795 e.g. no feature negotiation). Removed old experimental version.
7796 - implemented 'structured entity tags' for better cache correctness
7797 (structured entity tags ensure that caches which can deal with Vary
7798 will (eventually) be updated if the set of variants on the server
7800 - this involved adding a vlist_validator element to request_rec
7801 - this involved adding the ap_make_etag() function to the global API
7802 - modified guessing of charsets used by Apache negotiation algorithm
7803 to guess 'no charset' if the variant is not a text/* type
7804 - added code to sort multiviews variants into a canonical order so that
7805 negotiation results are consistent across backup/restores and mirrors
7806 - removed possibility of a type map file resolving to another type map
7807 file as its best variant

7819 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh kheldar.apana.org.au>]
7821 *) For %v log ServerName regardless of the UseCanonicalName
7822 setting (similarly for %p). [Dean Gaudet]
7824 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
7825 rather late (too late for some invocations of TestCompile).
7826 This improves the make environment available to TestCompile and
7827 the *.module scripts. [Martin Kraemer]
7829 *) The hashbang emulation code in ap_execve.c would interpret
7830 #!/hashbang/scripts correctly, but failed to fall back to a
7831 standard shell for scripts which did NOT start with #!
7832 Now SHELL_PATH is started in these cases. [Martin Kraemer]
7834 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg lentil.org>]
7837 *) Update APXS manual page: some -q option arguments were missing
7838 and another was incorrect. [Mark Anderson <mda discerning.com>] PR#3553
7840 *) Cleanup the command line options: `-?' was documented to show
7841 the usage list but does it with an error because `?' is not a valid
7842 command. OTOH a lot of users expect `-h' to print such a usage list and
7843 instead are annoyed for ages by our huge unreadable list of directives.
7844 So we now changed the command line options this way:
7846 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
7847 very similar to the popular linker option.
7849 Intent: while -l gives the small list of modules, -L now gives the
7850 large list of directives implemented by these modules. This is also
7851 consistent with -v (short version info) and -V (large version info).
7853 Intent: it's now the expected option ;-)
7854 The manual page was adjusted accordingly.

7857 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
7858 wasn't defined. [Rick Franchuk <rickf transpect.net>]
7860 *) Removed recently introduced bugs and disfigurements in APACI:
7861 o fixed argument line processing: using $args was broken: It was not
7862 initialized and using args="$args $apc_option" and even args="$args
7863 \"$apc_option\"" fails in the second processing round for any arguments
7864 containing whitespaces. The only correct way is to use the construct
7865 "$@" (but not possible here) or iterate _both_ times over the implicit
7866 argument line (no argument to for-loop) which is what we now use.
7867 o make --with-layout=Apache the default without creating
7868 redundancy (copying the --with-layout block in the argument parsing
7869 loop). We achieve this by using the "$@" construct together with the
7870 `set' command to prepend --with-layout=Apache to the command line in
7871 case --with-layout is not used.
7872 o fixed auto-suffix handling now that config.layout exists.
7873 Paths which are auto-suffixed are marked with a trailing plus sign in
7874 config.layout and every path now can be marked this way (not only the
7875 four paths for which we do it currently). Additionally the suffix is
7876 no longer a static one. Instead it's now `/<target>' where <target> is
7877 the argument of the --target option or per default `httpd'.
7878 o allow also tabs (and only spaces) where we match whitespaces
7879 o various fixes and cleanups related to used shell coding style
7880 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
7881 o trimmed output of --help to fit into 80 columns

7885 ap_single_module_init(), which are now used by mod_so to configure a module

7897 *) PORT: The I86 version of DGUX has support for strncasecmp and
7898 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247

7901 defined before it might be used. [Victor Khimenko]
7903 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
7904 [Tom Serkowski <tks bsdi.com>] PR#3453
7906 *) Make generation of src/Configuration.apaci more robust: It failed to
7907 differenciate between modules when one module name was a postfix of
7908 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
7909 just XXX (think about totally non-standard names like "apache_ssl", too).
7910 [Ralf S. Engelschall] PR#3380
7912 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
7913 since 1.3b7) and make whitespace handling more robust (it failed horrible
7914 when whitespaces were present in the arguments of -D options).
7915 [Ralf S. Engelschall] PR#3240
7917 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
7918 creates an external package shadow tree in DIR before the local build
7919 shadow tree is generated under DIR. This way one can have the extracted
7920 Apache distribution tree read-only on NFS or CDROM and still build Apache
7921 from these sources. An automatically triggered VPATH-like mechanism is
7922 provided through the TOP variable, too.

7936 and the usage page was inconsistent with the functionality and manpage.
7937 [Ralf S. Engelschall]
7939 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
7940 They can occur multiple times and their arguments (`xxx') are passed AS
7941 IS to the compiler/linker command. [Ralf S. Engelschall]
7943 *) Fixed possible (but harmless in practice) bug in the DBM lookup
7944 procedure of mod_rewrite: very long keys were truncated.
7945 [Ralf S. Engelschall]
7947 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
7948 identifier, currently "Apache" and "GNU" are pre-defined in the file
7949 config.layout. Custom layouts are possible by using FILE:ID as the
7950 argument where the layout ID is taken from FILE.
7952 The config.layout file consists of <Layout ID>..</Layout> sections
7953 where inside those sections "path_variable: path_value" pairs can be
7954 specified. These lines are converted to path_variable='path_value'.
7956 *) Add a DefaultLanguage directive so that files missing a language
7957 extension (e.g., .fr, .de) can be labelled as being some other
7958 default language. DefaultLanguage can appear in <Directory> and
7959 <Files> containers as well as .htaccess files. [Paul Sutton]
7962 *) Fix TARGET configuration when configuring and installing using
7963 APACI configure. TARGET now defines the basename of the configuration
7964 file, startup script, manual page, etc. log_error_core() now reports
7965 the server binary name given by argv[0]. TARGET can now also be defined
7966 with --target=TARGET parameter passed to APACI configure.

7992 *) Fallback to native compilers for IRIX-32 platform. It seems that
7993 a gcc 2.8.1 compiled apache is logging client addresses with all
7994 bits set (255.255.255.255). This is the second such problem caused
7995 by gcc 2.8.1 compiler. The first being broken semaphore locking.

8046 since it often includes file path info. Enable sending of error-notes
8047 on a 501 (Method Not Implemented). [Roy Fielding] PR#3173

8050 content type handler was specified but could not be found, which

8059 unavailable, an empty string was printed which was 2 bytes short.
8060 The size and description columns were therefore not aligned correctly.

8068 scoreboard file and avoid a string copy (as well as allow some
8069 further future enhancements). [Harrie Hazewinkel
8070 <harrie.hazewinkel jrc.it>]
8072 *) Add APACI --permute-module=foo:bar option which can be used to
8073 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
8074 in the Configuration[.apaci] file. Two special and important variants are
8075 supported for the option argument: first BEGIN:foo which permutes module
8076 mod_foo with the begin of the module list, i.e. it `moves' the module to
8077 the begin of the list (gives it lowest priority). And second foo:END
8078 which permutes mod_foo with the end of the module list, i.e. it `moves'
8079 the module to the end of the list (gives it highest priority).

8158 of the protocol processing, which is extra nice because it works
8159 between continuation lines, is almost no cost in the normal case
8160 of no extra whitespace, and saves memory. [Roy Fielding]

8306 determine whether a C header file exists or not. Because only this way
8307 we're safe against inter-header dependencies (which caused horrible
8308 portability problems). The only drawback is that we now have a CPP
8309 configuration variable which has to be determined first (we do a similar
8310 approach as GNU Autoconf does here). When all fails the user still has
8311 the possibility to override it manually via APACI or src/Configuration.
8312 As a fallback for the header check itself we can directly check the
8313 existance of the file under /usr/include, too.

8386 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
8388 *) The <IfModule and <IfDefine block starting directives now only
8389 allow exactly one argument. Previously, the optional negation
8390 character '!' could be separated by whitespace without a syntax
8391 error being reported, albeit defeating the IfModule functionality
8392 (enclosed directives would ALWAYS be executed). By using the
8393 stricter syntax, these hard-to-track errors can be avoided.
8396 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW

8404 different from the supplied path (e.g., ftp://user@host/ lives
8405 in /home/user, not in /, therefore clicking on "../" in the
8406 starting directory might send us to /home/).
8407 + When ftp login fails, (esp. when a user name was part of the
8408 URL already), we now return [401 Unauthorized ] to allow the
8409 browser to pop up an authorization dialog. This makes passwords
8410 slightly less visible (they don't appear in the regular log files)
8411 and implements a functionality that other www proxy servers
8415 *) Triggered by the recent "Via:" header changes, the proxy module would
8416 dump core for replies with invalid headers (e.g., duplicate
8417 "HTTP/1.0 200 OK" lines). These errors are now logged and the
8418 core dump is avoided. Also, broken replies are not cached.

8810 directory, bail out of the request with an error message. [W G Stoddard]
8812 *) WIN32 SECURITY: Eliminate directories consisting of three or more dots;
8813 these are treated by Win32 as if they are ".." but are not detected by
8814 other machinery within Apache. This is something of a kludge but
8815 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
8817 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
8818 pools and thus pollutes libap (until the pool stuff is moved there).
8821 *) IndexIgnore should be case-blind on Win32 (and any other case-aware
8822 but case-insensitive platforms). New #define for this added to conf.h
8823 (CASE_BLIND_FILESYSTEM). [Ken Coar] PR#2455
8825 *) Enable DSO support for OpenBSD in general, not only for 2.x, because it
8826 also works for OpenBSD 1.x. [Ralf S. Engelschall]
8828 *) PORT: Fix compilation problem on ARM Linux.
8829 [Sam Kington <sam illuminated.co.uk>] PR#2443
8831 *) Let APACI's configure script determine some configuration parameters
8832 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
8833 remove some of the classical hurdles for new users when setting up
8834 Apache. This is done per default because it is useful for the average
8835 user. Package authors can use the --without-confadjust option to disable
8836 these configuration adjustments.
8837 [Ralf S. Engelschall]
8839 *) Added an EXTRA_DEPS configuration parameter which can be used
8840 to add an extra Makefile dependency for the httpd target, for instance
8841 to external third-party libraries, etc.
8842 [Ralf S. Engelschall]
8844 *) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
8845 as <IfModule>..</IfModule> sections) which can be used to skip or process
8846 contained commands dependend of ``-D PARAMETER'' options on the command
8847 line. This can be used to achieve logical conditions like <IfDefine
8848 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
8849 and thus especially can be used for conditionally loading DSO-based
8850 modules via LoadModule, etc. [Ralf S. Engelschall]
8852 *) PORT: clean up a warning in mod_status for OS/2. [Brian Havard]
8854 *) Make table elements const. This may prevent obscure errors. [Ben Laurie]
8856 *) Fix parsing of FTP `SIZE' responses in proxy module: The newline was not
8857 truncated which forced following HTTP headers to be data in the HTTP
8858 reponse. [Ralf S. Engelschall, Charles Fu <ccwf bacchus.com>]
8861 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
8862 in top-level configure script to avoid sed fails on some platforms (for
8863 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
8864 output of Awk. [Bill Houle <bhoule sandiegoca.ncr.com>] PR#2435
8866 *) Improve performance of directory listings (mod_autoindex) by comparing
8867 integer keys (last-modified and size) as integers rather than converting
8868 them to strings first. Also use a set of explicit byte tests rather
8869 than strcmp() to check for parent directory-ness of an entry. Oh, and
8870 make sure the parent directory (if displayed) is *always* listed first
8871 regardless of the sort key. Overall performance winnage should be good
8872 in CPU time, instruction cache, and memory usage, particularly for large
8873 directories. [Ken Coar]
8875 *) Add a tiny but useful goody to APACI's configure script: The generation
8876 of a config.status script (as GNU Autoconf does) which remembers the used
8877 configure command and hence can be used to restore the configuration by
8878 just re-running this script or for remembering the configuration between
8880 [Ralf S. Engelschall]
8882 *) Add httpd -t (test) option for running configuration syntax tests only.
8883 If something is broken it complains and exits with a return code
8884 non-equal to 0. This can be used manually by the user to check the Apache
8885 configuration after editing and is also automatically used by apachectl
8886 on (graceful) restart command to make sure Apache doesn't die on restarts
8887 because of a configuration which is now broken since the last (re)start.
8888 This way `apachectl restart' can be used inside cronjobs without having
8889 to expect Apache to be falling down. Additionally the httpd -t can be run
8890 via `apachectl configtest'.
8891 [Ralf S. Engelschall] PR#2393
8893 *) Minor display fix for "install" target of top-level Makefile:
8894 the displayed installation command was incorrect although the

8910 functions which are in libdld under HPUX 9/10.
8911 [Ralf S. Engelschall] PR#2378
8913 *) Make sure the "install" target of the top-level Makefile doesn't break
8914 because of a return code of 1 from an "if" (for instance under braindead
8915 Ultrix the result code of an "if" construct is 1 if the "then" clause
8916 didn't match). [Ralf S. Engelschall]
8918 *) Add an additional "dummy" target to the "$(LIB)" target in generated
8919 modules/xxx/Makefile's to avoid problems with SVR4 Make under "full-DSO"
8920 situation (no libxxx.a built, only mod_xxx.so's) where LIB and OBJS are
8921 empty. [Ralf S. Engelschall, Dean Gaudet, Martin Kraemer]
8923 *) Replace two bad sprintf() calls with ap_snprintf() variants in
8924 mod_rewrite. [Ralf S. Engelschall]

8927 [David MacKenzie <djm va.pubnix.com>] PR#2384
8929 *) mod_log_config wouldn't let vhosts use log formats defined in the
8930 main server. [Christof Damian <damian mediaconsult.com>] PR#2090

8937 *) Fix a typo in pool debugging code. [Alvaro Martinez Echevarria]
8939 *) mod_unique_id did not work on alpha linux (in general on any

8943 *) PORT: Make SCO 5 (and probably 3) compile again. [Ben Laurie]
8945 *) PORT: NCR MPRAS systems have the same bug with SIGHUP restart that
8946 Solaris systems experience. So define WORKAROUND_SOLARIS_BUG.
8947 [Klaus Weber <kweber chephren.germany.ncr.com>] PR#1973
8949 *) Change "Options None" to "Options FollowSymLinks" in the
8950 <Directory /> section of the default access.conf-dist
8951 (and -win even though it doesn't matter there). This has better
8952 performance, and more intuitive semantics. [Dean Gaudet]

8957 *) Fix symbol export list (src/support/httpd.exp) after recent

8959 [Jens-Uwe Mager <jum helios.de>]
8961 *) Workaround for configure script and old `test' commands which do not
8962 support the -x flag (for instance under platforms like Ultrix). This is
8963 solved by another helper script findprg.sh which searches for Perl and
8964 Awk like PrintPath but _via different names_.

8989 Changes with Apache 1.3.0
8991 *) Using a type map file as a custom error document was not possible.
8992 [Lars Eilebrecht] PR#1031
8994 *) Avoid problems with braindead Awks by additionally searching for gawk
8995 and nawk in APACI's configure script.
8996 [Dave Dykstra <dwd bell-labs.com>, Ralf S. Engelschall] PR#2319
8998 *) Rename md5.h to ap_md5.h to avoid conflicts with native MD5 on
8999 some systems. [Randy Terbush]
9001 *) Change usage of perror()+fprintf(stderr,...) in mod_rewrite to
9002 more proper ap_log_error() variants.
9003 [Ralf S. Engelschall]
9005 *) Make sure the argument for the --add-module option to APACI's configure
9006 script is of type [path/to/]mod_xxx.c because all calculations inside
9007 configure and src/Configure depend on this.
9008 [Ralf S. Engelschall] PR#2307
9010 *) Changes usage of perror/fprintf to stderr to more proper ap_log_error
9011 in mod_mime, mod_log_referer, mod_log_agent, and mod_log_config.
9014 *) Various OS/2 cleanups ["Brian Havard" <brianh kheldar.apana.org.au>]
9016 *) PORT: QNX needed a #include <sys/mman.h>; and now it uses flock
9017 serialized accept to handle multiple sockets.
9018 [Rob Saccoccio <robs InfiniteTechnology.com>] PR#2295, 2296
9020 *) Have NT properly set the directory for CGI scripts
9021 (& other spawned children)
9022 [W G Stoddard <wgstodda us.ibm.com>]
9024 *) Propagate environment to CGI scripts correctly in Win32.
9025 [W G Stoddard <wgstodda us.ibm.com>] PR#2294
9027 *) Some symbol renaming:
9028 ap_spawn_child_err became ap_spawn_child
9029 ap_spawn_child_err_buff became ap_bspawn_child
9030 spawn_child was obsoleted and moved to compat.h
9033 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
9034 programs: ap_spawn_child_err() is used and the Win32 case now uses
9035 CreateProcess() instead of a low-level execl() (which caused problems in
9036 the past under Win32).
9037 [Ralf S. Engelschall]
9039 *) A few cosmetics and trivial enhancements to APXS to make the
9040 generated Makefile more user friendly. [Ralf S. Engelschall]
9042 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
9043 was updated to use the normal apache error processing, thereby allowing
9044 proxy errors to be treated by ErrorDocument's as well. For this
9045 purpose, a new module-to-core communication variable "error-notes"
9046 was introduced; the proxy (and possibly other modules) communicates
9047 its error text using this variable. Its content is copied to a new
9048 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
9049 The old proxy special error routine ap_proxy_log_uerror()
9050 was replaced by regular ap_log_error() calls, many messages were made
9052 [Martin Kraemer] PR#494, 1259
9054 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
9057 *) Transform the configure message "You need root privileges for suEXEC"
9058 from a fatal error into a (more friendly) warning because the building
9059 ("make") of Apache we can allow, of course. Root privileges are needed
9060 only for the installation step ("make install"). So make sure the
9061 user is aware of this fact but let him proceed as long as he can.
9062 [Ralf S. Engelschall] PR#2288
9064 *) Renamed three more functions to common ap_ prefix which we missed at the
9065 Big Symbol Renaming because they're #defines and not real C functions:
9066 is_default_port(), default_port(), http_method().
9067 [Ralf S. Engelschall]
9069 *) A zero-length name after a $ in an SSI document should cause
9070 just the $ to be in the expansion. This was broken during the
9071 security fixes in 1.2.5. [Dean Gaudet] PR#1921, 2249
9073 *) Call ap_destroy_sub_req() in ap_add_cgi_vars() to reclaim some
9074 memory. [Rob Saccoccio <robs InfiniteTechnology.com>] PR#2252
9076 *) Fix src/support/httpd.exp (DSO export file which is currently only
9077 used under AIX) because of recent changes to function names.
9078 [Ralf S. Engelschall]
9080 Changes with Apache 1.3b7
9082 *) Make sure a MIME-type can be forced via a RewriteRule even when no
9083 substitution takes place, for instance via the following rule:
9084 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
9085 requested by users in the past to force a single script without a .cgi
9086 extension and outside any cgi-bin dirs to be executed as a CGI program.
9087 [Ralf S. Engelschall] PR#2254
9089 *) A fix for protocol issues surrounding 400, 408, and
9090 414 responses. [Ed Korthof]
9092 *) Ignore MaxRequestsPerChild on WIN32. [Brian Behlendorf]
9094 *) Fix discrepancy in proxy_ftp.c which was causing failures when
9095 trying to connect to certain ftpd's, such as anonftpd.
9096 [Rick Ohnemus <rick ecompcon.com>]
9098 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
9099 logfile instead of fiddling around itself with child spawning stuff.
9100 [Ralf S. Engelschall]
9102 *) Made RefererIgnore case-insensitive.
9104 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
9107 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
9108 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
9111 *) Improve RFC1413 support. [Bob Beck <beck bofh.ucs.ualberta.ca>]
9113 *) Fix support script `dbmmanage': It was unable to handle some sort
9114 of passwords, especially passwords with "0" chars.
9115 [Ralf S. Engelschall] PR#2242
9117 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
9118 [Ben Laurie] PR#2238
9120 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
9121 library), so CGI handling has been changed to use Win32 native handles
9122 instead of C file descriptors.
9123 [Ben Laurie and Bill Stoddard <wgstodda us.ibm.com>] PR#1129, 1607
9125 *) The proxy cache would store an incorrect content-length in the cached
9126 file copy after a cache update. That resulted in repeated fetching
9127 of the original copy instead of using the cached copy.
9128 [Ernst Kloppenburg <kloppen isr.uni-stuttgart.de>] PR#2094
9130 *) The Makefiles assumed that DSO files are build via $(LD). This
9131 is broken for two reasons: First we never defined at least LD=ld
9132 somewhere to make sure this works (it was silently assumed that most Make
9133 provide a built-in LD definition - ARGL!) and second using the generic LD
9134 variable is not the truth. Instead a special variable named LD_SHLIB is
9135 reasonable because although "ld" is usually the default, the command for
9136 building DSO files can be "libtool" or even "cc" on some systems.
9137 [Ralf S. Engelschall]
9139 *) Replace the AddVersionPlatform directive with ServerTokens which
9140 provides for more control over the format of the Server:
9141 header line. SERVER_SUBVERSION is no longer supported;
9142 all module should use the ap_add_version_component()
9143 API function instead. [Jim Jagielski]
9145 *) Support for the NCR MP/RAS 3.0
9146 [John Withers <withers semi.kcsc.mwr.irs.gov>]
9148 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
9149 not retrieved in src/Configure and thus was not useable.
9150 [Ralf S. Engelschall]
9152 *) Various Makefile consistency cleanups:
9153 - make OSDIR also automatically be relative to src/ like INCDIR
9154 - SUBDIRS is now generated in src/Makefile only and not in
9155 Makefile.config because it is a local define for this location.
9156 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
9157 any Makefile but make sure that at least the "-K inline" is kept in
9159 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
9160 - updated the dependencies theirself
9161 - removed not existing SHLIB variable from "clean" targets
9162 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
9163 already exists and OBJS_PIC are also just plain objects and have not
9164 directly to do with "shared" things. The only difference is that they
9165 contain PIC. So OBJS_PIC is the more canonical name.
9166 - Updated the Makefile-dependency lines for OBJS_PIC
9167 - Removed the Makefile-dependency line in Configure to avoid double
9169 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
9170 of xxx.lo as GNU libtool does with its PIC objects
9171 - reduce local complexity in modules Makefile.tmpl by moving the last
9172 existing target "depend" to the generation section in Configure, too.
9173 - removed the historical $(SPACER) which was used in the past together
9174 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
9175 is no longer needed.
9176 - force the build and run of the gen_xxx programs under main/ as the
9177 first step before building the objects because it looks cleaner
9178 [Ralf S. Engelschall]
9180 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
9183 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
9186 *) WIN32: Don't force ISAPI headers to finish with \n.
9187 [Jim Patterson <Jim.Patterson Cognos.COM>, Ben Laurie] PR#2060
9189 *) When opening "configuration" files (like httpd.conf, htaccess
9190 and htpasswd), Apache will not allow them to be non-/dev/null
9191 device files. This closes a DoS hole. At the same time,
9192 we use ap_pfopen to open these files to handle timeouts.
9193 [Jim Jagielski, Martin Kraemer]
9195 *) Apache will now log the reason its httpd children exit if they exit
9196 due to an unexpected signal. (It requires a new porting define,
9197 SYS_SIGLIST, which if defined should point to a list of text
9198 descriptions of the signals available. See PORTING.) [Dean Gaudet]
9200 *) WIN32: chdir() doesn't make sense in a multithreaded environment
9201 like WIN32. Before, Win32 CGI's could have had sporadic failures
9202 if a chdir call from one thread was made between another chdir call
9203 and a spawn in another thread. So, for now don't chdir for CGI scripts
9204 in WIN32. The current CGI "spec" is unclear as to whether it's
9205 necessary. Long-term fix is to either serialize the chdir/spawn combo
9206 or use WIN32 native calls to spawn a process. This temp fix was
9207 necessary to remove this as a showstopper for 1.3's release.
9210 *) Cleanup the suEXEC support in APACI and make it more safe:
9211 1. Add big fat hint in INSTALL about risks and to read the
9212 htdocs/manual/suexec.html document before using the suexec-related
9214 2. Make sure the user has at least provided one --suexec-xxxx option
9215 (specifies suEXEC parameters) in addition to --enable-suexec option.
9216 If only --enable-suexec is given APACI stops with a hint to INSTALL
9217 and htdocs/manual/suexec.html documents.
9218 3. Provide two additional --suexec-xxxx options to make the suEXEC
9219 configuration complete (especially for package maintainers who else
9220 had to patch the source tree) by providing ways to configure minimal
9221 UID/GID and safe PATH, too.
9222 [Ralf S. Engelschall]
9224 *) Cleanup of the `configure --shadow' process:
9225 - make sure the configure script creates its temporary files in the
9226 shadow tree to avoid conflicts with parallel configure runs
9227 - removed unnecessary option "-r" from "rm" call for Makefiles
9228 - make sure the configure scripts creates the shadow-wrapper Makefile
9229 only when no shadow trees already exists
9230 - make sure "make distclean" removes the shadow-wrapper Makefile but only
9231 when no more shadow trees exists
9232 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
9233 as fast (in the past it needed 70sec, now it runs just 38sec)
9234 - make sure CVS does not complain about the created files
9235 Makefille.<gnutriple> and directories src.<gnutriple>
9236 [Ralf S. Engelschall]
9238 *) Added the ap_add_version_component() API routine and the
9239 AddVersionPlatform core directive. The first allows modules to
9240 declare themselves in the Server response header field value,
9241 augmenting the SERVER_SUBVERSION define in the Configuration file
9242 with run-time settings (more useful in a loadable-module environment).
9243 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
9244 into the server version string. [Ken Coar] PR#2056
9246 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
9249 *) Emit the "Accept-Range" header for the default handler.
9250 [Brian Behlendorf] PR#1464
9252 *) Add a note to httpd.conf-dist that apache will on some systems fail
9253 to start when the Group # is set to a negative or large positive value.
9256 *) Make sure the module execution order is correct even when some modules
9257 are loaded under runtime (`LoadModule') via the DSO mechanism:
9258 1. The list of loaded modules is now a dynamically allocated one
9259 and not the original statically list from modules.c
9260 2. The loaded modules are now correctly setup by LoadModule for
9261 later use by the AddModule command.
9262 3. When the DSO mechanism for modules is used APACI's `install'
9263 target now enables all created `LoadModule' lines per default because
9264 this is both already expected by the user _and_ needed to avoid
9265 confusion with the next point and reduces the Makefile.tmpl complexity
9266 4. When the DSO mechanism for modules is used, APACI's `install'
9267 target now additionally makes sure the module list is reconstructed
9268 via a complete `ClearModuleList+AddModule...' entry.
9269 5. The support tool `apxs' now also makes sure an AddModule command
9270 is added in addition to the LoadModule command.
9271 6. The modules.c generation was extended to now contain two
9272 comments to make sure no one is confused by the confusing terminology
9273 of loading/linking (we use load=link+load & link=activate instead of
9274 the obvious load=activate & link=link :-( )
9275 This way now there is no longer a difference under execution time between
9276 statically and dynamically linked modules.
9277 [Ralf S. Engelschall]
9279 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
9280 Big Symbol Renaming. [Ralf S. Engelschall]
9282 *) Add a comment to mod_example.c showing the format of a FLAG command
9285 *) Standardized the time format in mod_status to match that of other
9286 places in the code (e.g. DATE_GMT). PR#1551
9288 *) Fix handling of %Z in timefmt strings for those platforms with no time
9289 zone information in their tm struct. [Paul Eggert <eggert twinsun.com>]
9292 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
9293 feature compatible with 'UseCanonicalName off' by changing
9294 r->server->server_hostname to ap_get_server_name(). And I changed some
9295 functions which use r->server->port to use ap_get_server_port() instead,

9299 *) get/set_module_config are trivial enough to be better off inline. Worth
9300 1.5% performance boost. [Dean Gaudet]
9302 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
9303 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
9306 *) [BS2000 security] BS2000 needs an extra authentication to initialize
9307 the task environment to the unprivileged User id. Otherwise CGI scripts
9308 would have a way to gain super user access. [Martin Kraemer]
9310 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
9311 absolute path, only log base name of logging source as is done
9312 in unix. [Martin Kraemer]
9314 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
9315 the encoding type from the Accept-Encoding header (if it's there)
9316 and use it in the response, as that's probably what it'll be expecting.

9319 *) Fix to mod_alias: translate_alias_redir is dealing with
9320 a URI, not a filename, so the check for drive letters for win32
9321 and emx is not necessary. [Dean Gaudet]

9329 *) Child processes can now "signal" (by exiting with a status
9330 of APEXIT_CHILDFATAL) the parent process to abort and
9331 shutdown the server if the error in the child process was
9332 fatal enough. [Jim Jagielski]

9346 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
9347 Additionally the checks for finding the vendor DSO library were moved
9348 from mod_so.c to Configure because first it needs $PLAT etc. and second
9349 mod_so already uses an abstraction layer and does not fiddle with the
9350 vendor functions itself.
9351 [Jens-Uwe Mager, Ralf S. Engelschall]
9353 *) PORT: Some optimization defines for NetBSD
9354 [Jaromir Dolecek <dolecek ics.muni.cz>] PR#2165
9356 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
9357 [Jaromir Dolecek <dolecek ics.muni.cz>, Ralf S. Engelschall] PR#2158
9359 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
9360 AIX variants should work fine, too. Even AIX 3.x should work). This is
9361 accomplished by using the free DSO emulation code from Jens-Uwe Mager
9362 which we put into a os/unix/os-dso-aix.c file.
9363 [Ralf S. Engelschall]
9365 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
9366 that we should use NET_SIZE_T == int but the include files force size_t.
9367 [Ralf S. Engelschall]
9369 *) Fix two bugs in select() handling in http_main.c.
9372 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
9373 is unset (as it is in situations like timeouts) where it is unclear
9374 whether errno is set or not. [Martin Kraemer]
9376 *) Just having APACI's localstatedir is too general and not enough for most
9377 of the systems. 1.3b6 again required manual APACI patches by package
9378 maintainers from Red Hat and FreeBSD because for their filesystem layout a
9379 little bit more flexibility in configuring the paths is needed. Hence we
9380 provide three additional configure options (--runtimedir, --logfiledir,
9381 --proxycachedir) which now can be used for more granular adjustments if
9382 --localstatedir is not enough to fit the particular needs. As a nice
9383 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
9384 [Ralf S. Engelschall]
9386 *) Make the install root for "make install" in APACI's Makefile overrideable
9387 by package authors. This way we are even more friendly to package
9388 maintainers (especially Debian and Red Hat) who build for the real prefix
9389 via "configure --prefix=/<real>" but use a different local prefix via
9390 "make root=/tmp/apache install" for rolling the package without bristling
9391 the target location on their system.
9392 [Ralf S. Engelschall]
9394 *) Workaround sed limitations in APACI's configure script by now
9395 substituting in chunks of 50 commands (because for instance HPUX's vendor
9396 sed has a limit of max. 98 commands)
9397 [Ralf S. Engelschall] PR#2136
9399 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
9400 [Ralf S. Engelschall] PR#2140
9402 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
9403 RENAMING process because they are defined as pre-processor macros instead
9404 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
9405 [Ralf S. Engelschall]
9407 *) Workaround braindead AWK's when generating ap_config.h: The split() and
9408 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
9409 [Ralf S. Engelschall] PR#2139
9411 *) Various bugfixes and cleanups for the APACI configure script:
9412 o fix IFS handling for _nested_ situation
9413 o fix Perl interpreter search: take first one found instead of last one
9414 o fix DSO consistency check
9415 o print error messages to stderr instead of stdout
9416 o add install-quiet for --shadow situation to Makefile stub
9417 o reduce complexity by avoiding sed-hacks for rule and module list loops
9418 [Ralf S. Engelschall]
9420 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
9422 *) Make sure the input field separator (IFS) shell variable is explicitly
9423 initialized correctly before _every_ `for' loop and also restored after
9424 the loops. [Ralf S. Engelschall]
9426 *) Make sure that "make install" doesn't overwrite the `mime.types' and
9427 `magic' files from an existing Apache installation. Because people often
9428 customize these for own MIME and content types.
9429 [Ralf S. Engelschall]

9434 *) Fix the path to the ScoreBoardFile in the install-config target, too.
9435 [Ralf S. Engelschall] PR#2105
9437 *) Let "configure" clear out the users parameters (provided as shell
9438 variables) to avoid side-effects in "src/Configure" when the user
9439 exported them (which is not needed, but some users do it).
9440 [Ralf S. Engelschall] PR#2101
9442 *) Provide backward compatibility from some old src/Configuration.tmpl
9443 parameter names to the canonical Autoconf-style shell variable names. For
9444 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now

9451 *) Make `configure --compat' more "compatible" by first
9452 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
9453 second by making sure the "avoid-bristling-suffix" /apache is not
9454 appended to sysconfdir, datadir, localstatedir and includedir when
9455 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]

9463 *) Fix the path to the MimeMagicFile in the install-config target, too.
9464 [Ralf S. Engelschall] PR#2089
9466 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick colby.edu>]
9468 *) If you start apache with the -S command line option it will dump
9469 out the parsed vhost settings. This is useful for folks trying
9470 to figure out what is wrong with their vhost configuration.
9471 (Other dumps may be added in the future.) [Dean Gaudet]
9473 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
9474 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
9477 *) Because /usr/local/apache is the default prefix the ``configure
9478 --compat'' option no longer has to set prefix, again. This way the
9479 --compat option honors a leading --prefix option. [Lars Eilebrecht]
9481 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
9482 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
9483 to avoid "discard const" warnings. [Ralf S. Engelschall]
9485 *) If a specific handler is set for a file yet the request still
9486 ends up being handled by the default handler, log an error
9487 message before handling it. This catches things such as trying
9488 to use SSIs without mod_include enabled. [Marc Slemko]
9490 *) Fix error logging for the startup case where ap_log_error() still uses
9491 stderr as the target. Now the default log level is honored here, too.
9492 [Ralf S. Engelschall]
9494 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
9495 long" errors when generating the MODULES entry for src/Makefile
9496 [Ben Hyde, Ralf S. Engelschall]
9498 *) Make sure src/Configure doesn't complain about the old directory
9499 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
9501 Changes with Apache 1.3b6
9503 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
9505 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
9506 interface via the similar but proprietary HP/UX shl_xxx-style system
9507 calls. [Ralf S. Engelschall]
9509 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
9510 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
9511 Make. [Ralf S. Engelschall]
9513 *) ++++ THE BIG SYMBOL RENAMING ++++
9514 To avoid symbol clashes with third-party code compiled into the server,
9515 we globally applied the prefix "ap_" to the following classes of
9517 - Apache provided general functions (e.g., ap_cpystrn)
9518 - Public API functions (e.g., palloc, bgets)
9519 - Private functions which we can't make static (because of
9520 cross-object usage) but should be (e.g., new_connection)
9521 For backward source compatibility a new header file named compat.h was
9522 created which provides defines for the old symbol names and can be used
9523 by third-party module authors.
9526 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
9527 problem under SVR4 is that there is no command flag to force the linker
9528 to export the global symbols of the httpd executable therewith they are
9529 available to the DSO's. Instead of problematic hacks like creating a
9530 dummy.so file (containing dummy references to all global symbols) the
9531 httpd binary is linked against, we use a clean trick stolen from Perl 5:
9532 Placing the Apache core code itself into a DSO library named libhttpd.so.
9533 This way the global symbols _HAVE_ to be exported and thus are available
9534 to any manually loaded DSO's under runtime. To reduce the impact to the
9535 user to null we go even further and create a stub httpd executable which
9536 automatically keeps track of the DSO library loading itself and thus
9537 hides the complete mechanism from the user. Although the generation of
9538 this DSO library is automatically triggered for platforms which
9539 essentially need it (mostly all SVR4-derivates) it can be also enabled
9540 manually via the Rule SHARED_CORE. This can be interesting in the future
9541 where we perhaps exploit this libhttpd.so mechanism for providing nifty
9542 features like graceful upgrades, or whatever.
9543 [Ralf S. Engelschall, Martin Kraemer]
9545 *) Build the libraries before building the rest of the tools. [Ben Hyde]
9547 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
9548 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
9549 conventions while "clean" removes only stuff created by "all" targets,
9550 "distclean" additionally removes the stuff from the configuration
9551 process. This way "make distclean" (hence the name) provides a fresh
9552 source tree as it was for distribution.
9553 [Ralf S. Engelschall]
9555 *) Allow top-level (APACI) Makefile to break on build errors
9556 the same way the src/ subtree Makefiles breaks on them by replacing the
9557 initial APACI sed-subdir-display-kludge with a more clean
9558 variable-passing-solution: variable SDP can optionally hold the subdir
9559 prefix which is consistently used for displaying the subdir movement.
9560 This way even the top-level Makefile can stop correctly on errors as the
9561 user expects. [Ralf S. Engelschall]
9563 *) Fixed ordering of argument checks for RewriteBase directive.
9564 [Todd Eigenschink <eigenstr mixi.net>] PR#2045
9566 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
9567 indicating that a module is being compiled for dynamic loading. Also
9568 remove #define IS_MODULE from modules and add SHARED_MODULE define
9569 to the mak/dsp files. [Alexei Kosut]
9571 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
9572 since we are now logging APLOG_WARNING by default. [Roy Fielding]
9574 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
9576 *) Add documentation file and src/Configuration.tmpl entry for the
9577 experimental mod_mmap_static module. Because although it is and marked as
9578 an experimental one it is distributed and thus should be documented and
9579 prepared for configuration the same way as all others modules.
9580 [Ralf S. Engelschall]
9582 *) Add query (-q) option to apxs support tool to be able to manually query
9583 specific settings from apxs. This is needed for instance when you
9584 manually want to access Apache's header files and you need to assemble
9585 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
9586 [Ralf S. Engelschall]
9588 *) Now src/Configure uses a fallback strategy for the shared object support
9589 on platforms where no explicit information is available: If a Perl
9590 installation exists we ask it about its shared object support and if it's
9591 the dlopen-style one we shamelessly guess the compiler and linker flags
9592 for creating shared objects from Perls knowledge. Of course, the user is
9593 warning about what we are doing and informed that he should send us
9594 the guessed flags when they work. [Ralf S. Engelschall]
9596 *) Provide APACI --without-support option to be able to disable the build
9597 and installation of the support tools from the src/support/ area.
9598 Although its useful to have these installed per default we should provide
9599 a way to compile and install without them for backward-compatibility.
9600 [Ralf S. Engelschall]
9602 *) Add of the new APache eXtenSion (apxs) support tool for building and
9603 installing modules into an _already installed_ Apache package through the
9604 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
9605 this approach actually doesn't need the Apache source tree. The
9606 (APACI-installed) server package is enough, because this now includes the
9607 Apache C header files (PREFIX/include) and the new APXS tool
9608 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
9609 module authors to build their Apache modules _OUTSIDE_ the Apache source
9610 tree while avoiding them to fiddle around with the totally platform
9611 dependend way of compiling DSO files. The tool supports all ranges of
9612 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
9613 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
9614 on-the-fly generate a minimalistic Makefile and sample module for the
9615 first step to provide both a quick success event and to demonstrate the
9616 APXS mechanism to module authors. [Ralf S. Engelschall]
9618 *) Fix core dumps in use of CONNECT in proxy.
9619 [<Rainer.Scherg rexroth.de>] PR#1326, #1573, #1942
9621 *) Modify the log directives in httpd.conf-dist files to use CustomLog
9622 so that users have examples of how CustomLog can be used.
9625 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
9626 the Apache distribution tree. Until Apache 1.3 there was no real
9627 out-of-the-box batch-capable build and installation procedure for the
9628 complete Apache package. This is now provided by a top-level "configure"
9629 script and a corresponding top-level "Makefile.tmpl" file. The goal is
9630 to provide a GNU Autoconf-style frontend which is capable to both drive
9631 the old src/Configure stuff in batch and additionally installs the
9632 package with a GNU-conforming directory layout. Any options from the old
9633 configuration scheme are available plus a lot of new options for flexibly
9634 customizing Apache. [Ralf S. Engelschall]
9636 *) The floating point ap_snprintf code wasn't threadsafe.
9637 Had to remove the HAVE_CVT macro in order to do threadsafe
9638 calling of the ?cvt() floating point routines. [Dean Gaudet]
9640 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
9642 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
9643 [Jim Jagielski] PR#1901
9645 *) BUG: Configure was using TCC and CC inconsistently. Make sure
9646 Configure knows which CC we are using. [Jim Jagielski]
9648 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
9649 was defined in a parent directory. [Lars Eilebrecht]
9651 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
9652 a generic printf-style routine that can call arbitrary output
9653 routines. Use this to replace http_bprintf.c. Add new routines
9654 psprintf(), pvsprintf() which allocate the exact amount of memory
9655 required for a string from a pool. Use psprintf() to clean up
9656 various bits of code which used ap_snprintf()/pstrdup().
9659 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
9660 ap_snprintf() has different semantics and formatting codes than
9661 snprintf(). [Dean Gaudet]
9663 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
9664 is necessary on at least Solaris where the /etc/rc?.d scripts
9665 are run with these signals ignored, and "SIG_IGN" settings are
9666 maintained across exec().

9687 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
9690 *) After a SIGHUP the listening sockets in the parent weren't
9691 properly marked for closure on fork().
9692 [Jürgen Keil <jk tools.de>] PR#2000
9694 *) Allow %2F in two situations: 1) it is in the query part of the URI,
9695 therefore not exposed to %2F -> '/' translations and 2) the request
9696 is a proxy request, so we're not dealing with a local resource anyway.
9697 Without this, the proxy would fail to work for any URL's with
9698 %2f in them (occurs quite often in
9699 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
9701 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
9703 *) Make the shared object compilation command more portable by avoiding
9704 the direct combination of `-c' & `-o' which is not honored by some
9705 compilers like UnixWare's cc. [Ralf S. Engelschall]
9707 *) WIN32: the proxy was creating filenames missing the last four

9714 header if available. [Ralf S. Engelschall] PR#1183
9716 *) Reanimated the (still undocumented) proxy receive buffer size directive:
9717 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
9718 name was really too generic, added documentation for this directive to
9719 the mod_proxy.html and corrected the hyperlink to it in the

9722 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
9723 faster [Martin Kraemer]
9725 *) Make Configure die when you give it an unknown command switch.
9728 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
9729 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
9730 and per default compiled support programs have manual pages - just to
9731 document our stuff a little bit more and to be able to do really
9732 Unix-like installations ;-) [Ralf S. Engelschall]
9734 *) Major cleanups to the Configure script to make it and its generated
9735 Makefiles again readable and maintainable: add SRCDIR option, removed
9736 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
9737 generated sections, consequently added Makefile headers with inheritance
9738 information, added subdir movement messages for easier following where
9739 the build process currently stays (more verbose then standard Make, less
9740 verbose than GNU make), same style to comments in the Configure script,
9741 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
9743 *) Add the new ApacheBench program "ab" to src/support/: This is derived
9744 from the ZeusBench benchmarking program and can be used to determine the
9745 response performance of an Apache installation. This version is
9746 officially licensed with Zeus Technology, Ltd. See the license agreement
9747 statements in <199803171224.NAA24547 en1.engelschall.com> in apache-core.
9748 [Ralf S. Engelschall]
9750 *) API: Various core functions that are definately not part of the API
9751 have been made static, and a few have been marked API_EXPORT. Still
9752 more have been marked CORE_EXPORT and are not intended for general
9753 use by modules. [Doug MacEachern, Dean Gaudet]
9755 *) mod_proxy was not clearing the Proxy-Connection header from
9756 requests; now it does. This did not violate any spec, however
9757 causes poor interactions when you are talking to remote proxies.

9766 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
9768 *) Clean up some undocumented behavior of mod_setenvif related to
9769 "merging" two SetEnvIf directives when they match the same header
9770 and regex. Document that mod_setenvif will perform comparisons in
9771 the order they appear in the config file. Optimize mod_setenvif by
9772 doing more work at config time rather than at runtime.
9775 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's

9779 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
9782 *) Making the hard-coded cross-module function call mime_find_ct() (from
9783 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
9784 checking is really called even for proxy requests except for URLs with
9785 HTTP schemes (because there we can optimize by not running the type
9786 checking hooks due to the fact that the proxy gets the MIME Content-type
9787 from the remote host later). This change cleans up mod_mime by removing
9788 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
9789 especially unbundles mod_proxy and mod_mime. This way they both now can
9790 be compiled as shared objects and are no longer tied together.
9791 [Ralf S. Engelschall]
9793 *) util.c cleanup and speedup. [Dean Gaudet]
9795 *) API: Clarification, pstrndup() will always copy n bytes of the source
9796 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
9798 *) Mark module command_rec and handler_rec structures const so that they
9799 end up in the read-only data section (and are friendlier to systems
9800 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
9802 *) Add check to the "Port" directive to make sure the specified
9803 port is in the appropriate range. [Ben Hyde]
9805 *) Performance improvements to invoke_handler().
9806 [Dmitry Khrustalev <dima bog.msu.su>]
9808 *) Added support for building shared objects even for library-style modules
9809 (which are built from more than one object file). This now provides the
9810 ability to build mod_proxy as a shared object module. Additionally
9811 modules like mod_example are now also supported for shared object
9812 building because the generated Makefiles now no longer assume there is at
9813 least one statically linked module. [Ralf S. Engelschall]
9815 *) API: Clarify usage of content_type, handler, content_encoding,
9816 content_language and content_languages fields in request_rec. They
9817 must always be lowercased; and the strings pointed to shouldn't
9818 be modified (you must copy them to modify them). Fix a few bugs
9819 related to this. [Dean Gaudet]
9821 *) API: Clarification: except for RAW_ARGS, all command handlers can
9822 treat the char * parameters as permanent, and modifiable. There
9823 is no need to pstrdup() them. Clean up some needless pstrdup().
9826 *) Now mod_so keeps track of which module shared objects with which names
9827 are loaded and thus avoids multiple loading and unloading and irritating
9828 error_log messages. [Ralf S. Engelschall]
9830 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
9831 environment variable in the apache core. But that tweaking interferes
9832 with mod_setenv. So don't tweak if the user has specified an explicit
9833 TZ variable. [Jay Soffian <jay cimedia.com>] PR#1888
9835 *) rputs() did not calculate r->sent_bodyct properly.
9836 [Siegmund Stirnweiss <siegst kat.ina.de>] PR#1900
9838 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
9839 name, or left unset if this value is unavailable. Apache was setting
9840 it to the IP address when unavailable.
9841 [Tony Finch <fanf demon.net>] PR#1925
9843 *) Various improvements to the configuration and build support for compiling
9844 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
9845 OSF1 support with GCC and vendor compilers was added. This way shared
9846 object support is now provided out-of-the-box for FreeBSD, Linux,
9847 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
9848 [Ralf S. Engelschall]
9850 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
9851 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
9852 and USE_OS2_SCOREBOARD. [Dean Gaudet]
9854 *) Fix one more special locking problem for RewriteMap programs in
9855 mod_rewrite: According to the documentation of flock(), "Locks are on
9856 files, not file descriptors. That is, file descriptors duplicated
9857 through dup(2) or fork(2) do not result in multiple instances of a lock,
9858 but rather multiple references to a single lock. If a process holding a
9859 lock on a file forks and the child explicitly unlocks the file, the
9860 parent will lose its lock.". To overcome this we have to make sure the
9861 RewriteLock file is opened _AFTER_ the childs were spawned which is now
9862 the case by opening it in the child_init instead of the module_init API
9863 hook. [Ralf S. Engelschall] PR#1029
9865 *) Change to Location and LocationMatch semantics. LocationMatch no
9866 longer lets a single slash match multiple adjacent slashes in the
9867 URL. This change is for consistency with RewriteRule and
9868 AliasMatch. Multiple slashes have meaning in URLs that they do
9869 not have in (some) filesystems. Location on the other hand can
9870 be considered a shorthand for a more complicated regex, and it
9871 does match multiple slashes with a single slash -- which is
9872 also consistent with the Alias directive.
9873 [Dean Gaudet] related PR#1440
9875 *) Fix bug with mod_mime_magic causing certain files, including files
9876 of length 0, to result in no response from the server.
9879 *) The Configure script now generates src/include/ap_config.h which
9880 contains the set of defines used when Apache is compiled on a platform.
9881 This file can then be included by external modules before including
9882 any Apache header files in case they are being built separately from
9883 Apache. Along with this change, a couple of minor changes were
9884 made to make Apache's #defines coexist peacefully with any autoconf
9885 defines an external module might have. [Rasmus Lerdorf]
9887 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
9888 but without any RewriteXXXXX directives. Here mod_rewrite is given no
9889 chance by the API to initialize its per-server configuration and thus
9890 receives the wrong one from the main server. This is now avoided by
9891 remembering the server together with the config structure while
9892 configuring and later assuming there is no config when we see a
9893 difference between the remembered server and the one calling us.
9894 [Ralf S. Engelschall] PR#1790
9896 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
9897 is automatically disabled under configure time when the dbm_xxx functions
9898 are not available. Second, two heavy source code errors in the DBM
9899 support code were fixed. This makes DBM RewriteMap's usable again after
9900 a long time of brokenness. [Ralf S. Engelschall] PR#1696
9902 *) Now all configuration files support Unix-style line-continuation via
9903 the trailing backslash ("\") character. This enables us to write down
9904 complex or just very long directives in a more readable way. The
9905 backslash character has to be really the last character before the
9906 newline and it has not been prefixed by another (escaping) backslash.
9907 [Ralf S. Engelschall]
9909 *) When using ProxyPass the ?querystring was not passed correctly.
9910 [Joel Truher <truher wired.com>]
9912 *) To deal with modules being compiled and [dynamically] linked
9913 at a different time from the core, the SERVER_VERSION and
9914 SERVER_BUILT symbols have been abstracted through the new
9915 API routines apapi_get_server_version() and apapi_get_server_built().
9918 *) WIN32: Preserve trailing slash in canonical path (and hence
9919 in PATH_INFO). [Paul Sutton, Ben Laurie]
9921 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
9922 depending on the rev of Solaris and what mixture of modules
9923 are in use. So it has been disabled, and Solaris is back to
9924 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
9925 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
9926 up static content only servers. Or it may fail unpredictably.
9927 [Dean Gaudet] PR#1779, 1854, 1904
9929 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
9932 *) API: Rewrite of absoluteURI handling, and in particular how
9933 absoluteURIs match vhosts. Unless a request is a proxy request, a
9934 "http://host" url is treated as if a similar "Host:" header had been
9935 supplied. This change was made to support future HTTP/1.x protocols
9936 which may require clients to send absoluteURIs for all requests.
9938 In order to achieve this change subtle changes were made to the API. In a
9939 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
9940 that the unmodified uri can be retrieved easily. r->proxyreq is not set
9941 by the core, modules must set it during the post_read_request or
9942 translate_names phase.
9944 Plus changes to the virtualhost test suite for absoluteURI testing.
9946 This fixes several bugs with the proxy proxying requests to vhosts
9947 managed by the same httpd.
9950 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
9951 code from mod_rewrite. The vhost matching is now performed by a
9952 globally available function matches_request_vhost(). [Dean Gaudet]
9954 *) Reduce memory usage, and speed up ServerAlias support. As a
9955 side-effect users can list multiple ServerAlias directives
9956 and they're all considered.

9963 *) Make \\ behave as expected. [<Ronald.Tschalaer psi.ch>]
9965 *) Add the `%a' construct to LogFormat and CustomLog to log the client IP
9966 address. [Todd Eigenschink <eigenstr mixi.net>] PR#1885
9968 *) API: A new source module main/util_uri.c; It contains a routine
9969 parse_uri_components() and friends which breaks a URI into its component
9970 parts. These parts are stored in a uri_components structure called
9971 parsed_uri within each request_rec, and are available to all modules.
9972 Additionally, an unparse routine is supplied which re-assembles the URI
9973 components back to an URI, optionally hiding the username:password@ part
9974 from ftp proxy requests, and other useful routines. Within the structure,
9975 you find on a ready-for-use basis:
9976 scheme; /* scheme ("http"/"ftp"/...) */
9977 hostinfo; /* combined [user[:password]@]host[:port] */
9978 user; /* user name, as in http://user:passwd@host:port/ */
9979 password; /* password, as in http://user:passwd@host:port/ */
9980 hostname; /* hostname from URI (or from Host: header) */
9981 port_str; /* port string (integer representation is in "port") */
9982 path; /* the request path (or "/" if only scheme://host was given) */
9983 query; /* Everything after a '?' in the path, if present */
9984 fragment; /* Trailing "#fragment" string, if present */
9985 This is meant to serve as the platform for *BIG* savings in
9986 code complexity for the proxy module (and maybe the vhost logic).
9989 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
9990 ${map:key}) available for all location where a string is created in
9991 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
9992 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
9993 possible expansions are consequently usable at all string creation
9994 locations. [Ralf S. Engelschall]
9996 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
9997 and not 1) and the per-virtual-server merging of directives. Now all
9998 directives except `RewriteEngine' and `RewriteOption' are either
9999 completely overridden (default) or completely inherited (when
10000 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

10003 defined but disabled (`RewriteEngine off') in per-server context.

10006 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause

10009 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
10010 (like SunOS and FreeBSD) which don't accept the locking of pipes
10011 directly. A new directive RewriteLock is introduced which can be used to
10012 setup a separate locking file which then is used for synchronization.

10030 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
10031 type but with a special post-processing for the looked-up value: It
10032 parses it into alternatives according to `|' chars and then only one
10033 particular alternative is chosen randomly (this is an essential
10034 functionality needed for balancing between backend-servers when using
10035 Apache as a Reverse Proxy. The looked up value here is a list of
10036 servers). Second, `int' with the built-in maps named `tolower' and
10037 `toupper' which can be used to map URL parts to a fixed case (this is an
10038 essential feature to fix the case of server names when doing mass
10039 virtual-hosting with the help of mod_rewrite instead of using
10040 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
10041 Jay Soffian <jay cimedia.com>] PR#1631
10043 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
10044 This directive lets Apache adjust the URL in Location-headers on HTTP
10045 redirect responses sent by the remote server. This way the virtually
10046 mapped area is no longer left on redirects and thus by-passed which is
10047 especially essential when running Apache as a reverse proxy.

10163 preserves the encoding the client requests (for example if

10197 references in Makefiles have been changed to the simpler -Iinclude
10198 instead. In addition to simplifying the build a little bit, this
10199 also makes it clear when a module is referencing something in a
10200 other than kosher manner (e.g., the proxy including mod_mime.h).
10201 Module-private header files (the proxy, mod_mime, the regex library,

10232 *) mod_unique_id was erroneously generating a second unique id when
10233 an internal redirect occured. Such redirects occur, for example,
10234 when processing a DirectoryIndex match. [Dean Gaudet]
10236 *) API: table_add, table_merge, and table_set include implicit pstrdup()
10237 of the key and value. But in many cases this is not required
10238 because the key/value is a constant, or the value has been built
10239 by pstrcat() or other similar means. New routines table_addn,
10240 table_mergen, and table_setn have been added to the API, these
10241 routines do not pstrdup() their arguments. The core code and
10242 standard modules were changed to take advantage of these routines.
10243 The resulting server is up to 20% faster in some situations.
10245 Note that it is easy to get code subtly wrong if you pass a key/value
10246 which is in a pool other than the pool of the table. The only
10247 safe thing to do is to pass key/values which are in the pool of
10248 the table, or in one of the ancestors of the pool of the table.
10249 i.e. if the table is part of a subrequest, a value from the main
10250 request's pool is OK since the subrequest pool is a sub_pool of the
10251 main request's pool (and therefore has a lifespan at most as long as
10252 the main pool). There is debugging code which can detect improper
10253 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.

10259 MimeMagicFile directive then the module is not enabled.
10262 *) PORT: Some older *nix dialects cannot automatically start scripts
10263 which begin with a #! interpreter line (the shell starts the scripts

10270 have been writing to use table as if it were an opaque type, but even
10271 some standard modules got this wrong. By changing the definition
10272 to "typedef struct table table" module authors will receive compile
10273 time warnings that they're doing the wrong thing. This change
10274 facilitates future changes with more sophisticated table
10275 structures. Specifically, module authors should be using table_elts()
10276 to get access to an array_header * for the table. [Dean Gaudet]
10278 *) API: Renamed new_connection() to avoid namespace collision with LDAP
10279 library routines. [Ken Coar, Rasmus Lerdorf]
10281 *) WIN32: mod_speling is now available on the Win32 platform.
10284 *) For clarity the following compile time definition was changed:
10286 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
10288 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
10289 and not be a general notice that the OS has mmap(). Now the
10290 HAVE_MMAP/SHMGET #defines strictly are informational that the
10291 OS has that method of shared memory; the type to use for
10292 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
10293 and USE_SHMGET_SCOREBOARD). This allows outside modules to
10294 determine if shared memory is available and allows Apache
10295 to determine the best method to use for the scoreboard.
10298 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
10299 as do various earlier versions. It should be safe on all versions.
10300 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
10301 the slack code. A few other cleanups for Unixware.
10302 [Tom Hughes <thh cyberscience.com>] PR#1082, PR#1282, PR#1499, PR#1553
10304 *) PORT: A/UX can handle single-listen accepts without mutex
10305 locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]
10307 *) When die() happens we need to eat any request body if one exists.
10308 Otherwise we can't continue with a keepalive session. This shows up
10309 as a POST problem with MSIE 4.0, typically against pages which are
10310 authenticated. [Roy Fielding] PR#1399
10312 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization
10313 header will be passed to CGIs. This is generally a security hole, so
10314 it's not a default. [Marc Slemko] PR#549
10316 *) Fix Y2K problem with date printing in suexec log.
10317 [Paul Eggert <eggert twinsun.com>] PR#1343
10319 *) WIN32 deserves a pid file. [Ben Hyde]
10321 *) suexec errors now include the errno/description. [Marc Slemko] PR#1543
10323 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
10324 The choice of flock vs. fcntl was made based on timings which showed that
10325 even on non-NFS, non-exported filesystems fcntl() was an order of
10326 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
10327 that single socket users will see no difference. [Dean Gaudet] PR#467
10329 *) "File does not exist" error message was erroneously including the
10330 errno. [Marc Slemko]
10332 *) Improve the warning message generated when a client drops the
10333 connection (hits stop button, etc.) during a send. [Roy Fielding]
10335 *) Defining GPROF will disable profiling in the parent and enable it
10336 in the children. If you're profiling under Linux this is pretty much
10337 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
10339 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.
10342 *) The NeXT cc (which is gcc hacked up) doesn't appear to support some
10343 gcc functionality. Work around it.
10344 [Keith Severson <keith sssd.navy.mil>] PR#1613
10346 *) Some linkers complain when .o files contain no functions.
10347 [Keith Severson <keith sssd.navy.mil>] PR#1614
10349 *) Some const declarations in mod_imap.c that were added for debugging
10350 purposes caused some compilers heartburn without adding any
10351 significant value, so they've been removed. [Ken Coar]
10353 *) The src/main/*.h header files have had #ifndef wrappers added to
10354 insulate them against duplicate calls if they get included through
10355 multiple paths (e.g., in .c files as well as other .h files).
10358 *) The libap routines now have a header file for their prototypes,
10359 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
10361 *) mod_autoindex with a plaintext header file would emit the <PRE>
10362 start-tag before the HTML preamble, rather than after the preamble
10363 but before the header file contents. [John Van Essen <jve gamers.org>]
10366 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
10367 only an issue on systems without a MAXDNAME define or where
10368 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
10370 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
10371 is used to read various types of files such as htaccess and
10372 htpasswd files. [Marc Slemko]
10374 *) SECURITY: Ensure that the buffer returned by ht_time is always
10375 properly null terminated. [Marc Slemko]
10377 *) The "Connection" header could be sent back with multiple "close"
10378 tokens. Not an error, but a waste.
10379 [<Ronald.Tschalaer psi.ch>] PR#1683
10381 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
10382 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
10384 *) "basic" auth needs a case-insensitive comparison.
10385 [<Ronald.Tschalaer psi.ch>] PR#1666
10387 *) For maximum portability, the environment passed to CGIs should
10388 only contain variables whose names match the regex
10389 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
10390 underscores over any character outside the regex. This
10391 affects HTTP_* variables, in a way that should be backward
10392 compatible for all the standard headers; and affects variables
10393 set with SetEnv/BrowserMatch and similar directives.
10396 *) mod_speling returned incorrect HREF's when an ambigous match
10397 was found. Noticed by <robinton amtrash.comlink.de> (Soeren Ziehe)
10398 [Soeren Ziehe <robinton amtrash.comlink.de>, Martin Kraemer]
10400 *) PORT: Apache now compiles & runs on an EBCDIC mainframe
10401 (the Siemens BS2000/OSD family) in the POSIX subsystem
10404 *) PORT: Fix problem killing children when terminating. Allow ^C
10405 to shut down the server. [Brian Havard]
10407 *) pstrdup() is implicit in calls to table_* functions, so there's
10408 no need to do it before calling. Clean up a few cases.
10409 [Marc Slemko, Dean Gaudet]
10411 *) new -C and -c command line arguments
10413 -C "directive" : process directive before reading config files
10414 -c "directive" : process directive after reading config files
10416 httpd -C "PerlModule Apache::httpd_conf"
10417 [Doug MacEachern, Martin Kraemer]
10419 *) WIN32: Fix the execution of CGIs that are scripts and called
10420 with path info that does not have an '=' in.
10421 (eg. http://server/cgi-bin/printenv?foobar)
10422 [Marc Slemko] PR#1591
10424 *) WIN32: Fix a call to os_canonical_filename so it doesn't try to
10425 mess with fake filenames. This fixes proxy caching on
10428 *) SECURITY: General mod_include cleanup, including fixing several
10429 possible buffer overflows and a possible infinite loop.
10430 [Dean Gaudet, Marc Slemko]
10432 *) SECURITY: Numerous changes to mod_imap in a general cleanup
10433 including fixing a possible buffer overflow. [Dean Gaudet]
10435 *) WIN32: overhaul of multithreading code. Shutdowns are now graceful
10436 (connections are not dropped). Code can handle graceful restarts
10437 (but there is as yet no way to signal this to Apache). Various
10438 other cleanups. [Paul Sutton]
10440 *) The aplog_error changes specific to 1.3 introduced a buffer
10441 overrun in the (now legacy) log_printf function. Fixed.
10444 *) mod_digest didn't properly deal with proxy authentication. It
10445 also lacked a case-insensitive comparision of the "Digest"
10446 token. [Ronald Tschalaer <Ronald.Tschalaer psi.ch>] PR#1599
10448 *) A few cleanups in mod_status for efficiency. [Dean Gaudet]
10450 *) A few cleanups in mod_info to make it thread-safe, and remove an
10451 off-by-5 bug that could hammer \0 on the stack. [Dean Gaudet]
10453 *) no2slash() was O(n^2) in the length of the input. Make it O(n).
10456 *) API: migration from strncpy() to our "enhanced" version called
10457 ap_cpystrn() for performance and functionality reasons.
10458 Located in libap.a. [Jim Jagielski]
10460 *) table_set() and table_unset() did not deal correctly with
10461 multiple occurrences of the same key.
10462 [Stephen Scheck <sscheck infonex.net>, Ben Laurie] PR#1604
10464 *) The AuthName must now be enclosed in quotes if it is to contain
10465 spaces. [Ken Coar] PR#1195
10467 *) API: new function: ap_escape_quotes(). [Ken Coar] PR#1195
10469 *) WIN32: Work around optimiser bug that killed ISAPI in release
10470 versions. [Ben Laurie] PR#1533
10472 *) PORT: Update the MPE port [Mark Bixby, Jim Jagielski]
10474 *) Interim (slow) fix for p->sub_pool critical sections in
10475 alloc.c (affects win32 only). [Ben Hyde]
10477 *) non-WIN32 was missing destroy_mutex definition. [Ben Hyde]
10479 *) send_fd_length() did not calculate total_bytes_sent properly.
10480 [Ben Reser <breser regnow.com>] PR#1366
10482 *) The bputc() macro was not properly integrated with the chunking
10483 code; in many cases modules using bputc() could cause completely
10484 bogus chunked output. (Typically this will show up as problems
10485 with Internet Explorer 4.0 reading a page, but other browsers
10486 having no problem.) [Dean Gaudet]
10488 *) Create LARGE_WRITE_THRESHOLD define which determines how many
10489 bytes have to be supplied to bwrite() before it will consider
10490 doing a writev() to assemble multiple buffers in one system
10491 call. This is critical for modules such as mod_include,
10492 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
10493 strings in some cases. The result would be extra effort
10494 setting up writev(), and in many cases extra effort building
10495 chunks. The default is 31, it can be overriden at compile
10496 time. [Dean Gaudet]
10498 *) Move the gid switching code into the child so that log files
10499 and pid files are opened with the root gid.
10500 [Gregory A Lundberg <lundberg vr.net>]
10502 *) WIN32: Check for binaries by looking for the executable header
10503 instead of counting control characters.
10504 [Jim Patterson <Jim.Patterson Cognos.COM>] PR#1340
10506 *) ap_snprintf() moved from main/util_snprintf.c to ap/ap_snprintf.c
10507 so the functionality is available to applications other than the
10508 server itself (like the src/support tools). [Ken Coar]
10510 *) ap_slack() moved out of main/util.c into ap/ap_slack.c as part of
10511 the libap consolidation work. [Ken Coar]
10513 *) ap_snprintf() with a len of 0 behaved like sprintf(). This is not
10514 useful, and isn't what the standards require. Now it returns 0
10515 and writes nothing. [Dean Gaudet]
10517 *) When an error occurs in fcntl() locking suggest the user look up
10518 the docs for LockFile. [Dean Gaudet]
10520 *) Eliminate some dead code from writev_it_all().
10521 [Igor Tatarinov <tatarino prairie.NoDak.edu>]
10523 *) mod_autoindex had an fread() without checking the result code.
10524 It also wouldn't handle "AddIconByType (TXT,/icons/text.gif text/*"
10525 (note the missing closing paren) properly. [Dean Gaudet]
10527 *) It appears the "257th byte" bug (see
10528 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
10529 at the 256th byte as well. Fixed. [Dean Gaudet]
10531 *) PORT: Fix mod_mime_magic under OS/2, no support for block devices.
10534 *) Fix memory corruption caused by allocating auth usernames in the
10535 wrong pool. [Dean Gaudet] PR#1500
10537 *) Fix an off-by-1, and an unterminated string error in

10561 *) WIN32: Cure file leak in CGIs. [Peter Tillemans <pti net4all.be>] PR#1523
10563 *) proxy_ftp: the directory listings generated by the proxy ftp module
10564 now have a title in which the path components are clickable and allow
10565 quick navigation to the clicked-on directory on the currently listed
10566 ftp server. This also fixes a bug where the ".." directory links would
10567 sometimes refer to the wrong directory. [Martin Kraemer]
10569 *) WIN32: Allocate the correct amount of memory for the scoreboard.
10572 *) WIN32: Only lowercase the part of the path that is real. [Ben Laurie]
10575 *) Fix problems with timeouts in inetd mode and -X mode. [Dean Gaudet]

10578 error messages. [Ben Hyde]
10580 Changes with Apache 1.3b3
10582 *) WIN32: Work around brain-damaged spawn calls that can't deal
10583 with spaces and slashes. [Ben Laurie]
10585 *) WIN32: Fix the code so CGIs can use socket calls on Windows.
10586 The problem was that certain undocumented environment variables
10587 needed for sockets to work under Win32 were not being passed.
10588 [Frank Faubert <frank sane.com>]
10590 *) Add a "-V" command line flag to the httpd binary. This
10591 flag shows some of the defines that Apache was compiled with.
10592 It is useful for debugging purposes. [Martin Kraemer]
10594 *) Start separating the ap_*() routines into their own library, so they
10595 can be used by items in src/support among other things.
10596 [Ken Coar] PR#512, 905, 1252, 1308
10598 *) Give a more informative error when no AuthType is set.
10601 *) Remove strtoul() use from mod_proxy because it isn't available
10602 on all platforms. [Marc Slemko] PR#1214
10604 *) WIN32: Some Win32 systems terminated all responses after 16 kB.
10605 This turns out to be a bug in Winsock - select() doesn't always
10606 return the correct status. [Ben Laurie]
10608 *) Directives owned by http_core can now use the new check_cmd_context()
10609 routine to ensure that they're not being used within a container
10610 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
10612 *) PORT: Recent changes made it necessary to add explicit prototype
10613 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
10615 *) It was necessary to distinguish between resources which are
10616 allocated in the parent, for cleanup in the parent, and resources
10617 which are allocated in each child, for cleanup in each child.
10618 A new pool was created which is passed to the module child_init
10619 and child_exit functions; modules are free to register per-child
10620 cleanups there. This fixes a bug with reliable piped logs.
10623 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
10624 unless it was also doing FancyIndexes, but it displayed the
10625 HeaderName file at the top under all circumstances. It now shows
10626 the ReadmeName file for simple indices, too, as it should.
10629 *) http_core was mmap()ing even in cases where it wasn't going to
10630 read the file. [Ben Hyde <bhyde gensym.com>]
10632 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
10633 Now the rewriting engine (the heart of mod_rewrite) is organized more
10634 straight-forward, first time well documented and reduced to the really
10635 essential parts. All redundant cases were stripped off and processing now
10636 is the same for both per-server and per-directory context with only a
10637 minimum difference (the prefix stripping in per-dir context). As a
10638 side-effect some subtle restrictions and two recently discovered problems
10639 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
10640 context and restrictions on the substitution URL on redirects.
10641 Additionally some minor source cleanups were done.

10648 *) If ap_slack fails to allocate above the low slack line it's a good

10777 *) PORT: All SVR4 systems now use NET_SIZE_T = size_t, and
10778 use USE_SHMGET_SCOREBOARD.
10781 *) Various improvements in detecting config file errors (missing closing
10782 directives for <Directory>, <Files> etc. blocks, prohibiting global
10783 server settings in <VirtualHost> blocks, flagging unhandled multiple
10784 arguments to <Directory>, <Files> etc.)
10787 *) Add support to suexec wrapper program for mod_unique_id's UNIQUE_ID
10788 variable to provide this one to suexec'd CGIs, too.
10789 [M.D.Parker <mdpc netcom.com>] PR#1284
10791 *) New support tool: src/support/split-logfile, a sample Perl script which
10792 splits up a combined access log into separate files based on the
10793 name of the virtual host (listed first in the log records by "%v").
10796 Changes with Apache 1.3b2 (there is no 1.3b1)
10798 *) TestCompile was not passing $LIBS [Dean Gaudet]
10800 *) Makefile.tmpl was not using $CFLAGS in the link phase.
10803 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
10804 rudimentary memory debugger which can be used on live servers with
10805 low impact -- it sets all allocated and freed memory bytes to 0xa5.
10806 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
10807 and free() for each object. This is far more expensive and should
10808 only be used for testing with tools such as Electric Fence and
10809 Purify. See main/alloc.c for more details. [Dean Gaudet]
10811 *) Configure uses a sh trap and didn't set its exitcode properly.
10812 [Dean Gaudet] PR#1159
10814 *) Yet another vhost revamp. Add the NameVirtualHost directive which
10815 explicitly lists the ip:port pairs that are to be used for name-vhosts.
10816 From a given ip:port, regardless what the Host: header is, you can
10817 only reach the vhosts defined on that ip:port. The precedence of
10818 vhosts was reversed to match other precedences in the config --
10819 the earlier vhosts override the later vhosts. All vhost matching was
10820 moved into http_vhost.[ch]. [Dean Gaudet]
10822 *) ap_inline can be used to force inlining. GNUC __attribute__() can
10823 be used for whatever reason is appropriate (i.e. format() warnings
10824 for printf style functions). Both are enabled only with
10825 gcc >= 2.7.x (so that we have fewer support issues with older
10826 versions). [Dean Gaudet]
10828 *) Fix support for Proxy Authentication (we were testing the response
10829 status too early). [Marc Slemko]
10831 *) CoreDumpDirectory directive directs where the core file is
10832 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
10833 received. [Marc Slemko, Dean Gaudet]
10835 *) PORT: Support for Atari MINT.
10836 [Jan Paul Schmidt <Jan.P.Schmidt mni.fh-giessen.de>]
10838 *) When booting, apache will now detach itself from stdin, stdout,
10839 and stderr. stderr will not be detached until after the config
10840 files have been read so you will be able to see initial error
10841 messages. After that all errors are logged in the error_log.
10842 This makes it more convenient to start apache via rsh, ssh,
10843 or crontabs. [Dean Gaudet] PR#523
10845 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
10846 Also removed the auto-generated link to www.apache.org that was the
10847 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
10849 *) send_fb would not detect aborted connections in some situations.
10852 *) mod_include would use uninitialized data when parsing certain
10853 expressions involving && and ||. [Brian Slesinsky] PR#1139
10855 *) mod_imap should only handle GET methods. [Jay Bloodworth]
10857 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
10859 *) mod_autoindex improperly counted &escapes; as more than one
10860 character in the description. It also improperly truncated
10861 descriptions that were exactly the maximum length.
10864 *) RedirectMatch was not properly escaping the result (PR#1155). Also
10865 "RedirectMatch /advertiser/(.*) $1" is now permitted.
10868 *) mod_include now uses symbolic names to check for request success
10869 and return HTTP errors, and correctly handles all types of
10870 redirections (previously it only did temporary redirect correctly).
10871 [Ken Coar, Roy Fielding]
10873 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
10874 r->filename. Since those two are meant to be in sync with each other
10875 this is a bug. ["Paul B. Henson" <henson intranet.csupomona.edu>]
10877 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
10878 ["Kaufman, Steven E" <Steven.Kaufman unisys.com>]
10880 *) Inetd mode (which is buggy) uses timeouts without having setup the
10881 jmpbuffer. [Dean Gaudet] PR#1064
10883 *) Work around problem under Linux where a child will start looping
10884 reporting a select error over and over.
10885 [Rick Franchuk <rickf transpect.net>] PR#1107, 987, 588
10887 *) Fixed error in proxy_util.c when looping through multiple host IP
10888 addresses. [Lars Eilebrecht] PR#974
10890 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
10891 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
10892 bytes before writing, but it will never split a log entry across a
10893 buffer boundary. [Dean Gaudet]
10895 *) API: the short_score record has been split into two pieces, one which
10896 the parent writes on, and one which the child writes on. As part of
10897 this change the get_scoreboard_info() function was removed, and
10898 scoreboard_image was exported. This change fixes a race condition
10899 in file based scoreboard systems, and speeds up changes involving the
10900 scoreboard in earlier 1.3 development. [Dean Gaudet]
10902 *) API: New register_other_child() API (see http_main.h) which allows
10903 modules to register children with the parent for maintenance. It
10904 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
10906 *) API: New piped_log API (see http_log.h) which implements piped logs,
10907 and will use register_other_child to implement reliable piped logs
10908 when it is available. The reliable piped logs part can be disabled
10909 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
10910 logs is only available on Unix. [Dean Gaudet]
10912 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
10913 meets_conditions(). This allows conditional HTTP selection to be
10914 handled separately from the storing of the header fields, and provides
10915 the ability for CGIs to set their own ETags for conditional checking.
10916 [Ken Coar, Roy Fielding] PR#895
10918 *) Changes to mod_log_config to allow naming of format strings.
10919 Format nicknames are defined with "LogFormat fmt nickname", and can
10920 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
10923 *) New module, "mod_speling", which can help find files even when
10924 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
10926 *) API: New function child_terminate() triggers the child process to
10927 exit, while allowing the child finish what it needs to for the
10928 current request first.
10929 [Doug MacEachern, Alexei Kosut]
10931 *) Windows now defaults to using full status reports with mod_status.
10932 [Alexei Kosut] PR #1094
10934 *) *Really* disable all mod_rewrite operations if the engine is off.
10935 Some things (like RewriteMaps) were checked/performed even if they
10936 weren't supposed to be. [Ken Coar] PR #991
10938 *) Implement a new timer scheme which eliminates the need to call alarm() all
10939 the time. Instead a counter in the scoreboard for each child is used to
10940 show when the child has made forward progress. The parent samples this
10941 counter every scoreboard maintenance cycle, and issues SIGALRM if no
10942 progress has been made in the timeout period. This reduces the static
10943 request best-case syscall count to 22 from 29. This scheme is only
10944 used by systems with memory-based scoreboards. [Dean Gaudet]
10946 *) The proxy now properly handles CONNECT requests which are sent
10947 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
10949 *) A script called apachectl has been added to the support
10950 directory. This script allows you to do things such as
10951 "apachectl start" and "apachectl restart" from the command
10952 line. [Marc Slemko]
10954 *) Modules and core routines are now put into libraries, which
10955 simplifies the link line tremendously (among other advantages).
10958 *) Some of the MD5 names defined in Apache have been renamed to have
10959 an `ap_' prefix to avoid conflicts with routines supplied by
10960 external libraries. [Ken Coar]
10962 *) Removal of mod_auth_msql.c from the distribution. There are many
10963 other options for databases today. Rather than offer one option,
10964 offer none at this time. mod_auth_msql and other SQL database
10965 authentication modules can be found at the Apache Module Registry.
10966 http://modules.apache.org/ It would be nice to offer a generic
10967 mod_auth_sql option in the near future.
10969 *) PORT: BeOS support added [Alexei Kosut]
10971 *) Configure no longer accepts the -make option, since it creates
10972 Makefile on the fly based on Makefile.tmpl and Configuration.
10974 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
10975 of forcibly killing off all its processes and exiting without
10976 cleaning up. [Alexei Kosut]
10978 *) API: A new field in the request_rec, r->mtime, has been added to
10979 avoid gratuitous parsing of date strings. It is intended to hold
10980 the last-modified date of the resource (if applicable). An
10981 update_mtime() routine has also been added to advance it if
10982 appropriate. [Roy Fielding, Ken Coar]
10984 *) SECURITY: If a htaccess file can not be read due to bad permissions,
10985 deny access to the directory with a HTTP_FORBIDDEN. The previous
10986 behavior was to ignore the htaccess file if it could not be read.
10987 This change may make some setups with unreadable htaccess files
10988 stop working. [Marc Slemko] PR#817
10990 *) Add aplog_error() providing a mechanism to define levels of
10991 verbosity to the server error logging. This addition also provides
10992 the ability to log errors using syslogd. Error logging is configurable
10993 on a per-server basis using the LogLevel directive. Conversion
10994 of log_*() in progress. [Randy Terbush]
10996 *) Further enhance aplog_error() to not log filename, line number, and
10997 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
10999 *) WIN32: Canonicalise filenames under Win32. Short filenames are
11000 converted to long ones. Backslashes are converted to forward
11001 slashes. Case is converted to lower. Parts of URLs that do not
11002 correspond to files are left completely alone. [Ben Laurie]
11004 *) PORT: 2 new OSs added to the list of ports:
11005 Encore's UMAX V: Arieh Markel <amarkel encore.com>
11006 Acorn RISCiX: Stephen Borrill <sborrill xemplar.co.uk>
11008 *) Add the server version (SERVER_VERSION macro) to the "server
11009 configured and running" entry in the error_log. Also build an
11010 object file at link-time that contains the current time
11011 (SERVER_BUILT global const char[]), and include that in the
11012 message. [Ken Coar]
11014 *) Set r->headers_out when sending responses from the proxy.
11015 This fixes things such as the logging of headers sent from
11016 the proxy. [Marc Slemko] PR#659
11018 *) support/httpd_monitor is no longer distributed because the
11019 scoreboard should not be file based if at all possible. Use
11020 mod_status to see current server snapshot.
11022 *) (set_file_slot): New function, allowing auth directives to be
11023 independent of the server root, so the server documents can be
11024 moved to a different directory or machine more easily.
11025 [David J. MacKenzie]
11027 *) If no TransferLog is given explicitly, decline
11028 to log. This supports coexistence with other logging modules,
11029 such as the custom one that UUNET uses. [David J. MacKenzie]
11031 *) Check for titles in server-parsed HTML files.
11032 Ignore leading newlines and returns in titles. The old behavior
11033 of replacing a newline after <title> with a space causes the
11034 title to be misaligned in the listing. [David J. MacKenzie]
11036 *) Change mod_cern_meta to be configurable on a per-directory basis.
11037 [David J. MacKenzie]
11039 *) Add 'Include' directive to allow inclusion of configuration
11040 files within configuration files. [Randy Terbush]
11042 *) Proxy errors on connect() are logged to the error_log (nothing
11043 new); now they include the IP address and port that failed
11044 (*that's* new). [Ken Coar, Marc Slemko] PR#352
11046 *) Various architectures now define USE_MMAP_FILES which causes
11047 the server to use mmap() for static files. There are two
11048 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
11049 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
11050 number of bytes written in one cycle from a single mmap()d object,
11051 default 32768). [Dean Gaudet]
11053 *) API: Added post_read_request API phase which is run right after reading
11054 the request from a client, or right after an internal redirect. It is
11055 useful for modules setting environment variables that depend only on
11056 the headers/contents of the request. It does not run during subrequests
11057 because subrequests inherit pretty much everything from the main
11058 request. [Dean Gaudet]
11060 *) Added mod_unique_id which is used to generate a unique identifier for
11061 each hit, available in the environment variable UNIQUE_ID.
11064 *) init_modules is now called after the error logs have been opened. This
11065 allows modules to emit information messages into the error logs.
11068 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
11069 information for case where proxy module is not available. [Marc Slemko]
11071 *) PORT: Apache has need for mutexes to serialize its children around
11072 accept. In prior versions either fcntl file locking or flock file
11073 locking were used. The method is chosen by the definition of
11074 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
11075 and FLOCK for flock(). New options have been added:
11076 - SYSVSEM to use System V style semaphores
11077 - PTHREAD to use POSIX threads (appears to work on Solaris only)
11078 - USLOCK to use IRIX uslock
11079 Based on timing various techniques, the following changes were made
11081 - Linux 2.x uses flock instead of fcntl
11082 - Solaris 2.x uses pthreads
11083 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
11084 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
11085 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec vtcom.fr>,
11086 Martijn Koster <m.koster pobox.com>]
11088 *) PORT: The semantics of accept/select make it very desirable to use
11089 mutexes to serialize accept when multiple Listens are in use. But
11090 in the case where only a single socket is open it is sometimes
11091 redundant to serialize accept(). Not all unixes do a good job with
11092 potentially dozens of children blocked on accept() on the same
11093 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
11094 the server will avoid serialization when listening on only one socket,
11095 and use serialization when listening on multiple sockets.
11096 [Dean Gaudet] PR#467
11098 *) Configure changes: TestLib replaced by TestCompile, which has
11099 some additional capability (such as doing a sanity check of
11100 the compiler and flags selected); the version of Solaris is now
11101 available via the #define value of SOLARIS2; IRIX n32bit libs
11102 now supported and selectable by new Configuration Rule: IRIXN32;
11103 We no longer default to -O2 optimization. [Jim Jagielski]
11105 *) Updated Configure: Configuration now uses AddModule to specify
11106 module source or binary file location, relative to src directory.
11107 Modules can be dropped into modules/extra, or in their own
11108 directory, and modules can come with a Makefile or Configure can
11109 create one. Modules can add compiler or library information to
11110 generated Makefiles. [Paul Sutton]
11112 *) Source core re-organisation: distributed modules are now in
11113 modules/standard. All other source code is in main. OS-specific
11114 code is in os/{unix,emx,win32} directories. [Paul Sutton]
11116 *) mod_browser has been removed, since it's replaced by mod_setenvif.
11119 *) Fix another long-standing bug in sub_req_lookup_file where it would
11120 happily skip past access checks on subdirectories looked up with
11121 relative paths. (It's used by mod_dir, mod_negotiation,
11122 and mod_include.) [Dean Gaudet]
11124 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
11125 N is the number of <Directory> sections, and M is the number of
11126 components in the filename of an object.
11128 To achieve this optimization the following config changes were made:
11129 - Wildcards (* and ?, not the regex forms) in <Directory>s,
11130 <Files>s, and <Location>s now treat a slash as a special
11131 character. For example "/home/*/public_html" previously would
11132 match "/home/a/andrew/public_html", now it only matches things
11133 like "/home/bob/public_html". This mimics /bin/sh behaviour.
11134 - It's possible now to use [] wildcarding in <Directory>, <Files>
11136 - Regex <Directory>s are applied after all non-regex <Directory>s.
11140 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
11141 and corrupted paths. [Dean Gaudet]
11143 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
11144 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
11145 be accessed now via backreferences $1..$9 in RewriteConds test-against
11146 strings in addition to RewriteRules subst string. Second the grouped
11147 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
11148 via backreferences %1..%9 both in following RewriteCond test-against
11149 strings and RewriteRules subst string. This provides maximum flexibility
11150 through the use of backreferences.
11151 Additionally the rewriting engine was cleaned up by putting common
11152 code to the new expand_backrefs_inbuffer() function.
11153 [Ralf S. Engelschall]
11155 *) When merging the main server's <Directory> and <Location> sections into
11156 a vhost, put the main server's first and the vhost's second. Otherwise
11157 the vhost can't override the main server. [Dean Gaudet] PR#717
11159 *) The <Directory> code would merge and re-merge the same section after
11160 a match was found, possibly causing problems with some modules.
11163 *) ip-based vhosts are stored and queried using a hashing function, which
11164 has been shown to improve performance on servers with many ip-vhosts.
11165 Some other changes had to be made to accommodate this:
11166 - the * address for vhosts now behaves like _default_
11167 - the matching process now is:
11168 - match an ip-vhost directly via hash (possibly matches main
11170 - if that fails, just pretend it matched the main server
11171 - if so far only the main server has been matched, perform
11172 name-based lookups (ServerName, ServerAlias, ServerPath)
11173 *only on name-based vhosts*
11174 - if they fail, look for _default_ vhosts
11175 [Dean Gaudet, Dave Hankins <dhankins sugarat.net>]
11177 *) dbmmanage overhaul:
11178 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
11179 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
11180 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
11181 - provide better seed for rand
11182 - prompt for password as per getpass(3) (turn off echo, read from
11184 - use "newstyle" crypt based on $Config{osname} ($^O)
11185 - will not add a user if already in database, use new `update' command
11187 - added `check' command to check a users' password
11188 - added `import' command to convert existing password text-files or
11189 dbm files exported with `view'
11190 - more descriptive usage, general cleanup, 'use strict' clean, etc.
11193 *) Added psocket() which is a pool form of socket(), various places within
11194 the proxy weren't properly blocking alarms while registering the cleanup
11195 for its sockets. bclose() now uses pclose() and pclosesocket(). There
11196 was a bug where the client socket was being close()d twice due a still
11197 registered cleanup. [Dean Gaudet]
11199 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
11202 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
11203 [Jason Venner <jason idiom.com>] PR#667
11205 *) Enable ``=""'' for RewriteCond directives to match against
11206 the empty string. This is the preferred way instead of ``^$''.
11207 [Ralf S. Engelschall]
11209 *) Fixed an infinite loop in mod_imap for references above the server root
11210 [Dean Gaudet] PR#748
11212 *) mod_proxy now has a ReceiveBufferSize directive, similar to
11213 SendBufferSize, so that the TCP window can be set appropriately
11214 for LFNs. [Phillip A. Prindeville]
11216 *) mod_browser has been replaced by the more general mod_setenvif
11217 (courtesy of Paul Sutton). BrowserMatch* directives are still
11218 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
11219 UnSetEnvIfZero directives. [Ken Coar]
11221 *) "HostnameLookups double" forces double-reverse DNS to succeed in
11222 order for remote_host to be set (for logging, or for the env var
11223 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
11226 *) mod_access overhaul:
11227 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
11228 and cidr syntax (i.e. 10.1.0.0/16). PR#762
11229 - Critical path was sped up by pre-computing a few things at config time.
11230 - The undocumented syntax "allow user-agents" was removed,
11231 the replacement is "allow from env=foobar" combined with mod_browser.
11232 - When used with hostnames it now forces a double-reverse lookup
11233 no matter what the directory settings are. This double-reverse
11234 doesn't affect any of the other routines that use the remote
11235 hostname. In particular it's still passed to CGIs and the log
11236 without the double-reverse check. Related PR#860.
11239 *) When a large bwrite() occurs (larger than the internal buffer size),
11240 while there is already something in the buffer, apache will combine
11241 the large write and the buffer into a single writev(). (This is
11242 in anticipation of using mmap() for reading files.)
11245 *) In obscure cases where a partial socket write occurred while chunking,
11246 Apache would omit the chunk header/footer on the next block. Cleaned
11247 up other bugs/inconsistencies in error conditions in buff.c. Fixed
11248 a bug where a long pause in DNS lookups could cause the last packet
11249 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
11251 *) API: Added child_exit function to module structure. This is called
11252 once per "heavy-weight process" just before a server child exit()'s
11253 e.g. when max_requests_per_child is reached, etc.
11254 [Doug MacEachern, Dean Gaudet]
11256 *) mod_include cleanup showed that handle_else was being used to handle
11257 endif. It didn't cause problems, but it was cleaned up too.
11260 *) mod_cern_meta would attempt to find meta files for the directory itself
11261 in some cases, but not in others. It now avoids it in all cases.
11264 *) mod_mime_magic would core dump if there was a decompression error.

11267 *) PORT: some variants of DGUX require -lsocket -lnsl
11268 [Alexander L Jones <alex systems-options.co.uk>] PR#732
11270 *) mod_autoindex now allows sorting of FancyIndexed directory listings
11271 by the various fields (name, size, et cetera), either in ascending
11272 or descending order. Just click on the column header. [Ken Coar]
11274 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
11275 CPUs like the Alpha. Apache still stores ints in pointers, but that's
11276 the relatively safe direction. [Dean Gaudet] PR#344
11278 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
11279 [Igor N Kovalenko <infoh mail.wplus.net>] PR#683
11281 *) child_main avoids an unneeded call to select() when there is only one
11282 listening socket. [Dean Gaudet]
11284 *) In the event that the server is starved for idle servers it will
11285 spawn 1, then 2, then 4, ..., then 32 servers each second,
11286 doubling each second. It'll also give a warning in the errorlog
11287 since the most common reason for this is a poor StartServers
11288 setting. The define MAX_SPAWN_RATE can be used to raise/lower
11289 the maximum. [Dean Gaudet]
11291 *) Apache now provides an effectively unbuffered connection for
11292 CGI scripts. This means that data will be sent to the client
11293 as soon as the CGI pauses or stops output; previously, Apache would
11294 buffer the output up to a fixed buffer size before sending, which
11295 could result in the user viewing an empty page until the CGI finished
11296 or output a complete buffer. It is no longer necessary to use an
11297 "nph-" CGI to get unbuffered output. Given that most CGIs are written
11298 in a language that by default does buffering (e.g. perl) this
11299 shouldn't have a detrimental effect on performance.
11301 "nph-" CGIs, which formerly provided a direct socket to the client
11302 without any server post-processing, were not fully compatible with
11303 HTTP/1.1 or SSL support. As such they would have had to implement
11304 the transport details, such as encryption or chunking, in order
11305 to work properly in certain situations. Now, the only difference
11306 between nph and non-nph scripts is "non-parsed headers".
11307 [Dean Gaudet, Sameer Parekh, Roy Fielding]
11309 *) If a BUFF is switched from buffered to unbuffered reading the first
11310 bread() will return whatever remained in the buffer prior to the
11311 switch. [Dean Gaudet]
11313 Changes with Apache 1.3a1
11315 *) Added another Configure helper script: TestLib. It determines
11316 if a specified library exists. [Jim Jagielski]
11318 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
11319 [derived from patch from Jeff Hayes <jhayes aw.sgi.com>]
11322 *) PORT: Some architectures use size_t for various lengths in network
11323 functions such as accept(), and getsockname(). The definition
11324 NET_SIZE_T is used to control this. [Dean Gaudet]
11326 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
11327 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
11328 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
11330 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
11331 [Igor N Kovalenko <infoh mail.wplus.net>]
11333 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
11334 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
11335 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
11336 [Dean Gaudet] related PR#875
11338 *) API: Correct child_init() slot declaration from int to void, to
11339 match the init() declaration. Update mod_example to use the new
11342 *) added transport handle slot (t_handle) to the BUFF structure
11345 *) get_client_block() returns wrong length if policy is
11346 REQUEST_CHUNKED_DECHUNK.

11353 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
11354 ["Darren O'Shaughnessy" <darren aaii.oz.au>] PR#846
11356 *) AddModuleInfo directive for mod_info which allows you to annotate
11357 the output of mod_info. ["Lou D. Langholtz" <ldl usi.utah.edu>]
11359 *) Added NoProxy directive to avoid using ProxyRemote for selected
11360 addresses. Added ProxyDomain directive to cause unqualified
11361 names to be qualified by redirection.
11362 [Martin Kraemer <Martin.Kraemer mch.sni.de>]
11364 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
11365 header to the remote host in the proxy. [Sameer Parekh and
11368 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
11369 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
11370 URLs, fixed rewritelog(), fixed forced response code handling on
11371 redirects from within .htaccess files, disabled pipe locking under
11372 braindead SunOS 4.1.x, allow env variables to be set even on rules with
11373 no substitution, bugfixed situations where HostnameLookups is off, made
11374 mod_rewrite more thread-safe for NT port and fixed problem when creating
11375 an empty query string via "xxx?".
11376 This update also removes the copyright of Ralf S. Engelschall,
11377 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
11378 exclusively copyrighted by the Apache Group now. This happened because
11379 the author now has gifted mod_rewrite exclusively to the Apache Group and
11380 no longer maintains an external version.
11381 [Ralf S. Engelschall]
11383 *) API: Added child_init function to module structure. This is called
11384 once per "heavy-weight process" before any requests are handled.
11385 See http_config.h for more details. [Dean Gaudet]
11387 *) Anonymous_LogEmail was logging on each subrequest.
11388 [Dean Gaudet] PR#421, 868
11390 *) API: Added is_initial_req() which tests if the request being
11391 processed is the initial request, or a subrequest.
11394 *) Extended SSI (mod_include) now handles additional relops for
11395 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
11397 *) Configure fixed to correctly propagate user-selected options and
11398 settings (such as CC and OPTIM) to Makefiles other than
11399 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
11401 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
11402 directory indices to start with the contents of the HeaderName file
11403 if there is one. If there isn't one, the behaviour is unchanged.
11404 [Ken Coar, Roy Fielding, Andrey A. Chernov]
11406 *) WIN32: Modules can now be dynamically loaded DLLs using the
11407 LoadModule/LoadFile directives. Note that module DLLs must be
11408 compiled with the multithreaded DLL version of the runtime library.
11409 [Alexei Kosut and Ben Laurie]
11411 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
11412 This allows the admin to completely remove automatic indexing
11413 from the server, while still supporting the basic functions of
11414 trailing-slash redirects and DirectoryIndex files. Note that if
11415 you're carrying over an old Configuration file and you use directory
11416 indexing then you'll want to add:
11418 Module autoindex_module mod_autoindex.o
11420 before mod_dir in your Configuration. [Dean Gaudet]
11422 *) popendir/pclosedir created to properly protect directory scanning.
11423 [Dean Gaudet] PR#525
11425 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
11426 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
11427 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
11430 *) The AccessFileName directive can now take more than one filename.
11431 ["Lou D. Langholtz" <ldl usi.utah.edu>]
11433 *) The new mod_mime_magic can be used to "magically" determine the type
11434 of a file if the extension is unknown. Based on the unix file(1)
11435 command. [Ian Kluft <ikluft cisco.com>]
11437 *) We now determine and display the time spent processing a
11438 request if desired. [Jim Jagielski]
11440 *) mod_status: PID field of "dead" child slots no longer displays
11441 main httpd process's PID. [Jim Jagielski]
11443 *) Makefile.nt added - to build all the bits from the command line:
11444 nmake -f Makefile.nt
11445 Doesn't yet work properly. [Ben Laurie]
11447 *) Default text of 404 error is now "Not Found" rather than the
11448 potentially misleading "File Not Found". [Ken Coar]
11450 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
11451 for the net if we require people that actually need this data to
11452 enable it. [Linus Torvalds]
11454 *) directory_walk() is an expensive function, keep a little more state to
11455 avoid needless string counting. Add two new functions make_dirstr_parent
11456 and make_dirstr_prefix which replace all existing uses of make_dirstr.
11457 The new functions are a little less general than make_dirstr, but
11458 work more efficiently (less memory, less string counting).
11461 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
11462 to LDFLAGS) to avoid complications with lex rules in make files.
11463 [Dean Gaudet] PR#372
11465 *) run_method optimized to avoid needless scanning over NULLs in the
11466 module list. [Dean Gaudet]
11468 *) Revamp of (unix) scoreboard management code such that it avoids
11469 unnecessary traversals of the scoreboard on each hit. This is
11470 particularly important for high volume sites with a large
11471 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
11472 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
11473 httpd.h. [Dean Gaudet]
11475 *) In configurations using multiple Listen statements it was possible for
11476 busy sockets to starve other sockets of service. [Dean Gaudet]
11478 *) Added hook so standalone_main can be replaced at compile time
11479 (define STANDALONE_MAIN)
11482 *) Lowest-level read/write functions in buff.c will be replaced with
11483 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
11484 compile time. The default sfio discipline will behave as apache
11485 would without sfio compiled in.
11488 *) Enhance UserDir directive (mod_userdir) to accept a list of
11489 usernames for the 'disable' keyword, and add 'enable user...' to
11490 selectively *en*able userdirs if they're globally disabled.
11493 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
11494 will work with Netscape dbm files. (dbmmanage will probably not
11495 work however.) [Alexander Spohr <aspohr netmatic.com>] PR#444
11497 *) Add a ListenBacklog directive to control the backlog parameter
11498 passed to listen(). Also change the default to 511 from 512.
11501 *) API: A new handler response DONE which informs apache that the
11502 request has been handled and it can finish off quickly, similar to
11503 how it handles errors. [Rob Hartill]
11505 *) Turn off chunked encoding after sending terminating chunk/footer
11506 so that we can't do it twice by accident. [Roy Fielding]
11508 *) mod_expire also issues Cache-Control: max-age headers.
11511 *) API: Added kill_only_once option for free_proc_chain so that it won't
11512 aggressively try to kill off specific children. For fastcgi.
11513 [Stanley Gambarin <gambarin OpenMarket.com>]
11515 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
11517 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
11518 When used together, these cause mod_dir to emit HEIGHT and WIDTH
11519 attributes in the FancyIndexing IMG tags. [Ken Coar]
11521 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
11523 *) PORT: Added Windows NT support
11524 [Ben Laurie and Ambarish Malpani <ambarish valicert.com>]
11526 Changes with Apache 1.2.6
11528 *) mod_include when using XBitHack Full would send ETags in addition to
11529 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
11530 [Dean Gaudet] PR#1133
11532 *) SECURITY: When a client connects to a particular port/addr, and
11533 gives a Host: header ensure that the virtual host requested can
11534 actually be reached via that port/addr. [Ed Korthof <ed organic.com>]
11536 *) Support virtual hosts with wildcard port and/or multiple ports
11537 properly. [Ed Korthof <ed organic.com>]
11539 *) Fixed some case-sensitivity issues according to RFC2068.
11542 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
11543 and mod_include.c. [Dean Gaudet]
11545 *) Variable 'cwd' was being used pointlessly before being set.
11548 *) SIGURG doesn't exist on all platforms.
11549 [Mark Andrew Heinrich <heinrich tinderbox.Stanford.EDU>]
11551 *) When an error occurs during a POST, or other operation with a
11552 request body, the body has to be read from the net before allowing
11553 a keepalive session to continue. [Roy Fielding] PR#1399
11555 *) When an error occurs in fcntl() locking suggest the user look up
11556 the docs for LockFile. [Dean Gaudet]
11558 *) table_set() and table_unset() did not deal correctly with
11559 multiple occurrences of the same key. [Stephen Scheck
11560 <sscheck infonex.net>, Ben Laurie] PR#1604
11562 *) send_fd_length() did not calculate total_bytes_sent properly in error
11563 cases. [Ben Reser <breser regnow.com>] PR#1366
11565 *) r->connection->user was allocated in the wrong pool causing corruption
11566 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
11568 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
11569 Also removed the auto-generated link to www.apache.org that was the
11570 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
11572 *) Multiple "close" tokens may have been set in the "Connection"
11573 header, not an error, but a waste.
11574 [<Ronald.Tschalaer psi.ch>] PR#1683
11576 *) "basic" and "digest" auth tokens should be tested case-insensitive.
11577 [<Ronald.Tschalaer psi.ch>] PR#1599, PR#1666
11579 *) It appears the "257th byte" bug (see
11580 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
11581 at the 256th byte as well. Fixed. [Dean Gaudet]
11583 *) mod_rewrite would not handle %3f properly in some situations.
11586 *) Apache could generate improperly chunked HTTP/1.1 responses when
11587 the bputc() or rputc() functions were used by modules (such as
11588 mod_include). [Dean Gaudet]
11590 *) #ifdef wrap a few #defines in httpd.h to make life easier on
11591 some ports. [Ralf Engelschall]
11593 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
11595 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
11597 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
11599 Changes with Apache 1.2.5
11601 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
11602 only an issue on systems without a MAXDNAME define or where
11603 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
11605 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
11608 *) Fix core dump in the ftp proxy when reading incorrectly formatted
11609 directory listings. [Marc Slemko]
11611 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
11614 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
11615 is used to read various types of files such as htaccess and
11616 htpasswd files. [Marc Slemko]
11618 *) SECURITY: Ensure that the buffer returned by ht_time is always
11619 properly null terminated. [Marc Slemko]
11621 *) SECURITY: General mod_include cleanup, including fixing several
11622 possible buffer overflows and a possible infinite loop. This cleanup
11623 was done against 1.3 code and then backported to 1.2, the result
11624 is a large difference (due to indentation cleanup in 1.3 code).
11625 Users interested in seeing a smaller set of relevant differences
11626 should consider comparing against src/modules/standard/mod_include.c
11627 from the 1.3b3 release. Non-indentation changes to mod_include
11628 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
11630 *) SECURITY: Numerous changes to mod_imap in a general cleanup
11631 including fixing a possible buffer overflow. This cleanup also
11632 was done with 1.3 code as a basis, see the previous note
11633 about mod_include. [Dean Gaudet]
11635 *) SECURITY: If a htaccess file can not be read due to bad
11636 permissions, deny access to the directory with a HTTP_FORBIDDEN.
11637 The previous behavior was to ignore the htaccess file if it could not
11638 be read. This change may make some setups with unreadable
11639 htaccess files stop working. PR#817 [Marc Slemko]
11641 *) SECURITY: no2slash() was O(n^2) in the length of the input.
11642 Make it O(n). This inefficiency could be used to mount a denial
11643 of service attack against the Apache server. Thanks to
11644 Michal Zalewski <lcamtuf boss.staszic.waw.pl> for reporting
11645 this. [Dean Gaudet]
11647 *) mod_include used uninitialized data for some uses of && and ||.
11648 [Brian Slesinsky <bslesins wired.com>] PR#1139
11650 *) mod_imap should decline all non-GET methods.
11651 [Jay Bloodworth <jay pathways.sde.state.sc.us>]
11653 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
11655 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
11656 r->filename. Since those two are meant to be in sync with each other
11657 this is a bug. ["Paul B. Henson" <henson intranet.csupomona.edu>]
11659 *) mod_include did not properly handle all possible redirects from sub-
11660 requests. [Ken Coar]
11662 *) Inetd mode (which is buggy) uses timeouts without having setup the
11663 jmpbuffer. [Dean Gaudet] PR#1064
11665 *) Work around problem under Linux where a child will start looping
11666 reporting a select error over and over.
11667 [Rick Franchuk <rickf transpect.net>] PR#1107
11669 Changes with Apache 1.2.4
11671 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
11672 always making requests with the full-URI instead of just the URI path.
11673 [Marc Slemko, Roy Fielding]
11675 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
11676 on this platform. [Marc Slemko]
11678 Changes with Apache 1.2.3
11680 *) The request to a remote proxy was mangled if it was generated as the
11681 result of a ProxyPass directive. URL schemes other than http:// were not
11682 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
11683 PR#812 [Lars Eilebrecht]
11685 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
11686 information for case where proxy module is not available. [Marc Slemko]
11688 *) Force proxy to always respond as HTTP/1.0, which it was failing to
11689 do for errors and cached responses. [Roy Fielding]
11691 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
11693 Changes with Apache 1.2.2 [not released]
11695 *) Fixed another long-standing bug in sub_req_lookup_file where it would
11696 happily skip past access checks on subdirectories looked up with relative
11697 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
11700 *) Add lockfile name to error message printed out when
11701 USE_FLOCK_SERIALIZED_ACCEPT is defined.
11704 *) Enhanced the chunking and error handling inside the buffer functions.
11705 [Dean Gaudet, Roy Fielding]
11707 *) When merging the main server's <Directory> and <Location> sections into
11708 a vhost, put the main server's first and the vhost's second. Otherwise
11709 the vhost can't override the main server. [Dean Gaudet] PR#717
11711 *) The <Directory> code would merge and re-merge the same section after
11712 a match was found, possibly causing problems with some modules.
11715 *) Fixed an infinite loop in mod_imap for references above the server root.
11716 [Dean Gaudet] PR#748
11718 *) mod_include cleanup showed that handle_else was being used to handle
11719 endif. It didn't cause problems, but it was cleaned up too.
11722 *) Last official synchronization of mod_rewrite with author version (because
11723 mod_rewrite is now directly developed by the author at the Apache Group):
11724 o added diff between mod_rewrite 3.0.6+ and 3.0.9
11725 minus WIN32/NT stuff, but plus copyright removement.
11727 - workaround for detecting infinite rewriting loops
11728 - fixed setting of env vars when "-" is used as subst string
11729 - fixed forced response code on redirects (PR#777)
11730 - fixed cases where r->args is ""
11731 - kludge to disable locking on pipes under braindead SunOS
11732 - fix for rewritelog in cases where remote hostname is unknown
11733 - fixed totally damaged request_rec walk-back loop
11734 o remove static from local data and add static to global ones.
11735 o replaced ugly proxy finding stuff by simple
11736 find_linked_module("mod_proxy") call.
11737 o added missing negation char on rewritelog()
11738 o fixed a few comment typos

11746 "downgrade-1.0" which causes Apache to pretend it received a 1.0.

11775 has been added to take care of that. [Roy Fielding] PR#378
11777 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
11778 release version number, such that it always increases along the
11779 same lines as our source code branching. [Roy Fielding]
11781 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
11783 Changes with Apache 1.2.1
11785 *) SECURITY: Don't serve file system objects unless they are plain files,
11786 symlinks, or directories. This prevents local users from using pipes
11787 or named sockets to invoke programs for an extremely crude form of
11790 *) SECURITY: HeaderName and ReadmeName were settable in .htaccess and
11791 could contain "../" allowing a local user to "publish" any file on
11792 the system. No slashes are allowed now. [Dean Gaudet]
11794 *) SECURITY: It was possible to violate the symlink Options using mod_dir
11795 (headers, readmes, titles), mod_negotiation (type maps), or
11796 mod_cern_meta (meta files). [Dean Gaudet]
11798 *) SECURITY: Apache will refuse to run as "User root" unless
11799 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
11801 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
11802 if it contained a .htaccess disallowing symlinks. This is contrary
11803 to the rule that symlink permissions are tested with the symlink
11804 options of the parent directory. [Dean Gaudet] PR#353
11806 *) CONFIG: The LockFile directive can be used to place the serializing
11807 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
11808 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
11811 *) Request processing now retains state of whether or not the request
11812 body has been read, so that internal redirects and subrequests will
11813 not try to read it twice (and block). [Roy Fielding]
11815 *) Add a placeholder in modules/Makefile to avoid errors with certain
11816 makes. [Marc Slemko]
11818 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.
11819 [Dean Gaudet] PR#644
11821 *) mod_include was not properly changing the current directory.
11822 [Marc Slemko] PR#742
11824 *) Attempt to work around problems with third party libraries that do not
11825 handle high numbered descriptors (examples include bind, and
11826 solaris libc). On all systems apache attempts to keep all permanent
11827 descriptors above 15 (called the low slack line). Solaris users
11828 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
11829 which keeps all non-FILE * descriptors above 255. On all systems
11830 this should make supporting large numbers of vhosts with many open
11831 log files more feasible. If this causes trouble please report it,
11832 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
11833 [Dean Gaudet] various PRs
11835 *) Related to the last entry, network sockets are now opened before
11836 log files are opened. The only known case where this can cause
11837 problems is under Solaris with many virtualhosts and many Listen
11838 directives. But using -DHIGH_SLACK_LINE=256 described above will
11839 work around this problem. [Dean Gaudet]
11841 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
11844 *) Improved unix error response logging. [Marc Slemko]
11846 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
11847 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
11848 when a URL http://... was used in conjunction with a special
11849 redirect flag, e.g. R=permanent, the permanent status was lost.
11850 [Ronald Tschalaer <Ronald.Tschalaer psi.ch>, Ralf S. Engelschall]
11852 *) If an object has multiple variants that are otherwise equal Apache
11853 would prefer the last listed variant rather than the first.
11854 [Paul Sutton] PR#94
11856 *) "make clean" at the top level now removes *.o. [Dean Gaudet] PR#752
11858 *) mod_status dumps core in inetd mode. [Marc Slemko and Roy Fielding]
11861 *) pregsub had an off-by-1 in its error checking code. [Alexei Kosut]

11884 Changes with Apache 1.2
11886 Changes with Apache 1.2b11
11888 *) Fixed open timestamp fd in proxy_cache.c [Chuck Murcko]
11890 *) Added undocumented perl SSI mechanism for -DUSE_PERL_SSI and mod_perl.
11891 [Doug MacEachern, Rob Hartill]
11893 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
11894 reading from one buffer and writing to another, at least until it has
11895 a custom timeout handler. [Roy Fielding and Petr Lampa]
11897 *) Fixed problem on IRIX with servers hanging in IdentityCheck,
11898 apparently due to a mismatch between sigaction and setjmp.
11899 [Roy Fielding] PR#502
11901 *) Log correct status code if we timeout before receiving a request (408)
11902 or if we received a request-line that was too long to process (414).
11903 [Ed Korthof and Roy Fielding] PR#601
11905 *) Virtual hosts with the same ServerName, but on different ports, were
11906 not being selected properly. [Ed Korthof]
11908 *) Added code to return the requested IP address from proxy_host2addr()
11909 if gethostbyaddr() fails due to reverse DNS lookup problems. Original
11910 change submitted by Jozsef Hollosi <hollosi sbcm.com>.
11911 [Chuck Murcko] PR#614
11913 *) If multiple requests on a single connection are used to retrieve
11914 data from different virtual hosts, the virtual host list would be
11915 scanned starting with the most recently used VH instead of the first,
11916 causing most virtual hosts to be ignored.
11917 [Paul Sutton and Martin Mares] PR#610
11919 *) The OS/2 handling of process group was broken by a porting patch for
11920 MPE, so restored prior code for OS/2. [Roy Fielding and Garey Smiley]
11922 *) Inherit virtual server port from main server if none (or "*") is
11923 given for VirtualHost. [Dean Gaudet] PR#576
11925 *) If the lookup for a DirectoryIndex name with content negotiation
11926 has found matching variants, but none are acceptable, return the
11927 negotiation result if there are no more DirectoryIndex names to lookup.
11928 [Petr Lampa and Roy Fielding]
11930 *) If a soft_timeout occurs after keepalive is set, then the main child
11931 loop would try to read another request even though the connection
11932 has been aborted. [Roy Fielding]
11934 *) Configure changes: Allow for whitespace at the start of a
11935 Module declaration. Also, be more understanding about the
11936 CC=/OPTIM= format in Configuration. Finally, fix compiler
11937 flags if using HP-UX's cc compiler. [Jim Jagielski]
11939 *) Subrequests and internal redirects now inherit the_request from the
11940 original request-line. [Roy Fielding]
11942 *) Test for error conditions before creating output header fields, since
11943 we don't want the error message to include those fields. Likewise,
11944 reset the content_language(s) and content_encoding of the response
11945 before generating or redirecting to an error message, since the new
11946 message will have its own Content-* definitions. [Dean Gaudet]
11948 *) Restored the semantics of headers_out (headers sent only with 200..299
11949 and 304 responses) and err_headers_out (headers sent with all responses).
11950 Avoid the overhead of copying tables if err_headers_out is empty
11951 (the usual case). [Roy Fielding]
11953 *) Fixed a couple places where a check for the default Content-Type was
11954 not properly checking both the value configured by the DefaultType
11955 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
11956 of DEFAULT_TYPE to match the documented default (text/plain).
11957 [Dean Gaudet] PR#506
11959 *) Escape the HTML-sensitive characters in the Request-URI that is
11960 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
11962 *) Properly initialize the flock structures used by the mutex locking
11963 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
11966 *) The method for determining PATH_INFO has been restored to the pre-1.2b
11967 (and NCSA httpd) definition wherein it was the extra path info beyond
11968 the CGI script filename. The environment variable FILEPATH_INFO has
11969 been removed, and instead we supply the original REQUEST_URI to any
11970 script that wants to be Apache-specific and needs the real URI path.
11971 This solves a problem with existing scripts that use extra path info
11972 in the ScriptAlias directive to pass options to the CGI script.
11975 *) The _default_ change in 1.2b10 will change the behaviour on configs
11976 that use multiple Listen statements for listening on multiple ports.
11977 But that change is necessary to make _default_ consistent with other
11978 forms of <VirtualHost>. It requires such configs to be modified
11979 to use <VirtualHost _default_:*>. The documentation has been
11980 updated. [Dean Gaudet] PR#530
11982 *) If an ErrorDocument CGI script is used to respond to an error
11983 generated by another CGI script which has already read the message
11984 body of the request, the server would block trying to read the
11985 message body again. [Rob Hartill]
11987 *) signal() replacement conflicted with a define on QNX (and potentially
11988 other platforms). Fixed. [Ben Laurie] PR#512
11990 Changes with Apache 1.2b10
11992 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
11993 to be configured via -D in Configuration. [Dean Gaudet] PR#449
11995 *) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]
11997 *) Added prototype for mktemp() for SUNOS4 [Marc Slemko]
11999 *) In mod_proxy.c, check return values for proxy_host2addr() when reading
12000 config, in case the hostent struct returned is trash.
12001 [Chuck Murcko] PR #491
12003 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
12004 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
12006 Changes with Apache 1.2b9 [never announced]
12008 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
12009 changes and in anticipation of 1.2 final release. [Roy Fielding]
12011 *) Fix problem with scripts not receiving a SIGPIPE when client drops
12012 the connection (e.g., when user presses Stop). Apache will now stop
12013 trying to send a message body immediately after an error from write.
12014 [Roy Fielding and Nathan Kurz] PR#335
12016 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
12017 than mod_alias, and mod_alias has higher priority than mod_proxy;
12018 rearranged other modules to enhance understanding of their purpose
12019 and relative order (and maybe even reduce some overhead).
12020 [Roy Fielding and Sameer Parekh]
12022 *) Fix graceful restart. Eliminate many signal-related race
12023 conditions in both forms of restart, and in SIGTERM. See
12024 htdocs/manual/stopping.html for details on stopping and
12025 restarting the parent. [Dean Gaudet]
12027 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
12028 memory allocator to avoid a behaviour that required extra blocks to
12029 be allocated. [Dean Gaudet]
12031 *) Allow suexec to access files relative to current directory but not
12032 above. (Excluding leading / or any .. directory.) [Ken Coar]
12035 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
12036 PR#367, 368, 354, 453
12038 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
12039 while obtaining the /~user and save the username in a separate data
12040 area so that it won't be overwritten by the call to getgrgid(), and
12041 fix some misuse of the pool string allocation functions. Also fixes
12042 a general problem with parsing URL query info into args for CGI scripts.
12043 [Roy Fielding] PR#339, 367, 354, 453
12045 *) Fix IRIX warning about bzero undefined. [Marc Slemko]
12047 *) Fix problem with <Directory proxy:...>. [Martin Kraemer] PR#271
12049 *) Corrected spelling of "authoritative". AuthDBAuthoratative became
12050 AuthDBAuthoritative. [Marc Slemko] PR#420
12052 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
12054 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
12055 object that can't be PUT, or FOOBAR for some method FOOBAR that
12056 apache doesn't know about at all). Log 404s that occur in mod_include.
12057 [Paul Sutton, John Van Essen]
12059 *) If a soft timeout (or lingerout) occurs while trying to flush a
12060 buffer or write inside buff.c or fread'ing from a CGI's output,
12061 then the timeout would be ignored. [Roy Fielding] PR#373
12063 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
12064 parsing of headers. If the terminating empty-line CRLF occurs starting
12065 at the 256th or 257th byte of output, then Navigator will think a normal
12066 image is invalid. We are guessing that this is because their initial
12067 read of a new request uses a 256 byte buffer. We check the bytes written
12068 so far and, if we are about to tickle the bug, we instead insert a
12069 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
12071 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
12072 of an external redirection. [Roy Fielding and Paul Sutton]
12074 *) Configure would create a broken Makefile if the configuration file
12075 contained a commented-out Rule. [Roy Fielding]
12077 *) Promote per_dir_config and subprocess_env from the subrequest to the
12078 main request in mod_negotiation. In particular this fixes a bug
12079 where <Files> sections wouldn't properly apply to negotiated content.
12082 *) Fix a potential deadlock in mod_cgi script_err handling.
12083 [Ralf S. Engelschall]
12085 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
12086 [Mitchell Blank Jr]
12088 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
12089 .htaccess files because the RewriteBase was not replaced correctly.
12090 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
12091 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
12093 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
12094 1.x the settings are those of pre-1.2b8. For 2.x we include
12095 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
12096 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
12097 [Dean Gaudet] PR#336, PR#340
12099 *) Redirect did not preserve ?query_strings when present in the client's
12100 request. [Dean Gaudet]
12102 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
12104 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
12106 *) Add UnixWare compile/install instructions. [Chuck Murcko]
12108 *) Add mod_example (illustration of API techniques). [Ken Coar]
12110 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
12112 *) Improve handling of directories when filenames have spaces in them.
12115 *) For hosts with multiple IP addresses, try all additional addresses if
12116 necessary to get a connect. Fail only if hostent address list is
12117 exhausted. [Chuck Murcko]
12119 *) More signed/unsigned port fixes. [Dean Gaudet]
12121 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
12124 Changes with Apache 1.2b8
12126 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
12127 to it. [Marc Slemko]
12129 *) The addition of <Location> and <File> directives made the
12130 sub_req_lookup_simple() function bogus, so we now handle
12131 the special cases directly. [Dean Gaudet]
12133 *) We now try to log where the server is dumping core when a fatal
12134 signal is received. [Ken Coar]
12136 *) Improved lingering_close by adding a special timeout, removing the
12137 spurious log messages, removing the nonblocking settings (they
12138 are not needed with the better timeout), and adding commentary
12139 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
12140 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
12142 *) Send error messages about setsockopt failures to the server error
12143 log instead of stderr. [Roy Fielding]
12145 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
12147 *) Stopgap solution for CGI 3-second delay with server-side includes: if
12148 processing a subrequest, allocate memory from r->main->pool instead
12149 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
12150 in the middle of an SSI request. [Dean Gaudet] PR #122
12152 *) Fixed status of response when POST is received for a nonexistent URL
12153 (was sending 405, now 404) and when any method is sent with a
12154 full-URI that doesn't match the server and the server is not acting
12155 as a proxy (was sending 501, now 403). [Roy Fielding]
12157 *) Host port changed to unsigned short. [Ken Coar] PR #276
12159 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
12161 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
12163 *) Report extra info from errno with many errors that cause httpd to exit.
12164 spawn_child, popenf, and pclosef now have valid errno returns in the
12165 event of an error. Correct problems where errno was stomped on
12166 before being reported. [Dean Gaudet]
12168 *) In the proxy, if the cache filesystem was full, garbage_coll() was
12169 never called, and thus the filesystem would remain full indefinitely.
12170 We now also remove incomplete cache files left if the origin server
12171 didn't send a Content-Length header and either the client has aborted
12172 transfer or bwrite() to client has failed. [Petr Lampa]
12174 *) Fixed the handling of module and script-added header fields.
12175 Improved the interface for sending header fields and reduced
12176 the duplication of code between sending okay responses and errors.
12177 We now always send both headers_out and err_headers_out, and
12178 ensure that the server-reserved fields are not being overridden,
12179 while not overriding those that are not reserved. [Roy Fielding]
12181 *) Moved transparent content negotiation fields to err_headers_out
12182 to reflect above changes. [Petr Lampa]
12184 *) Fixed the determination of whether or not we should make the
12185 connection persistent for all of the cases where some other part
12186 of the server has already indicated that we should not. Also
12187 improved the ordering of the test so that chunked encoding will
12188 be set whenever it is desired instead of only when KeepAlive
12189 is enabled. Added persistent connection capability for most error
12190 responses (those that do not indicate a bad input stream) when
12191 accessed by an HTTP/1.1 client. [Roy Fielding]
12193 *) Added missing timeouts for sending header fields, error responses,
12194 and the last chunk of chunked encoding, each of which could have
12195 resulted in a process being stuck in write forever. Using soft_timeout
12196 requires that the sender check for an aborted connection rather than
12197 continuing after an EINTR. Timeouts that used to be initiated before
12198 send_http_header (and never killed) are now initiated only within or
12199 around the routines that actually do the sending, and not allowed to
12200 propagate above the caller. [Roy Fielding]
12202 *) mod_auth_anon required an @ or a . in the email address, not both.
12205 *) per_dir_defaults weren't set correctly until directory_walk for
12206 name-based vhosts. This fixes an obscure bug with the wrong config
12207 info being used for vhosts that share the same ip as the server.
12210 *) Improved generation of modules/Makefile to be more generic for
12211 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
12213 *) Generate makefile dependency for Configuration based on the actual
12214 name given when running the Configure process. [Dean Gaudet]
12216 *) Fixed problem with vhost error log not being set prior to
12217 initializing virtual hosts. [Dean Gaudet]
12219 *) Fixed infinite loop when a trailing slash is included after a type map
12220 file URL (extra path info). [Petr Lampa]
12222 *) Fixed server status updating of per-connection counters. [Roy Fielding]
12224 *) Add documentation for DNS issues (reliability and security), and try
12225 to explain the virtual host matching process. [Dean Gaudet]
12227 *) Try to continue gracefully by disabling the vhost if a DNS lookup
12228 fails while parsing the configuration file. [Dean Gaudet]
12230 *) Improved calls to setsockopt. [Roy Fielding]
12232 *) Negotiation changes: Don't output empty content-type in variant list;
12233 Output charset in variant list; Return sooner from handle_multi() if
12234 no variants found; Add handling of '*' wildcard in Accept-Charset.
12235 [Petr Lampa and Paul Sutton]
12237 *) Fixed overlaying of request/sub-request notes and headers in
12238 mod_negotiation. [Dean Gaudet]
12240 *) If two variants' charset quality are equal and one is the default
12241 charset (iso-8859-1), then prefer the variant that was specifically
12242 listed in Accept-Charset instead of the default. [Petr Lampa]
12244 *) Memory allocation problem in push_array() -- it would corrupt memory
12245 when nalloc==0. [Kai Risku <krisku tf.hut.fi> and Roy Fielding]
12247 *) invoke_handler() doesn't handle mime arguments in content-type
12248 [Petr Lampa] PR#160
12250 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
12253 *) Fixed problem with ErrorDocument not working for virtual hosts
12254 due to one of the performance changes in 1.2b7. [Dean Gaudet]
12256 *) Log an error message if we get a request header that is too long,
12257 since it may indicate a buffer overflow attack. [Marc Slemko]
12259 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
12260 not reject URLs without a double-slash, as per RFC2068 section 3.2.
12261 [Ken Coar] PR #146, #187
12263 *) Added table entry placeholder for new header_parser callback
12264 in all of the distributed modules. [Ken Coar] PR #191
12266 *) Allow for cgi files without the .EXE extension on them under OS/2.
12267 [Garey Smiley] PR #59
12269 *) Fixed error message when resource is not found and URL contains
12270 path info. [Petr Lampa and Dean Gaudet] PR #40
12272 *) Fixed user and server confusion over what should be a virtual host
12273 and what is the main server, resulting in access to something
12274 other than the name defined in the virtualhost directive (but
12275 with the same IP address) failing. [Dean Gaudet]
12277 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
12278 AIX; improves the redirection stuff to enable the users to generally
12279 redirect to http, https, gopher and ftp; added TIME variable for
12280 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
12281 special patterns >STRING, <STRING and =STRING to RewriteCond, which
12282 can be used in conjunction with %{TIME} or other variables to create
12283 time-dependent rewriting rules. [Ralf S. Engelschall]
12285 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
12286 Module authors may need to adjust their code for proper cleanup to take
12287 place (that is, call note_cleanups_for_fd()). This change fixes problems
12288 with file descriptors being erroneously closed when the proxy module was
12289 in use. [Ben Laurie]
12291 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
12292 initgroups() to hose the group information needed for later
12293 comparisons. [Randy Terbush]
12295 *) Remove unnecessary call to va_end() in create_argv() which
12296 caused a SEGV on some systems.
12298 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
12301 *) Clear memory allocated for listeners. [Randy Terbush]
12303 *) Improved handling of IP address as a virtualhost address and
12304 introduced "_default_" as a synonym for the default vhost config.
12305 [Dean Gaudet] PR #212
12307 Changes with Apache 1.2b7
12309 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom yk.fujitsu.co.jp>]
12311 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
12313 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
12314 - replace protocol response numbers with symbols
12315 - save variant-list into main request notes
12316 - free allocated memory from subrequests
12317 - merge notes, headers_out and err_headers_out
12319 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
12320 "HTTP/#.# ###*" to be more lenient about what we accept.
12323 *) more proxy FTP bug fixes:
12324 - Changed send_dir() to remove user/passwd from displayed URL.
12325 - Changed login error messages to be more descriptive.
12326 - remove setting of SO_DEBUG socket option
12327 - Make ftp_getrc() more lenient about multiline responses,
12328 specifically, 230 responses which don't have continuation 230-
12329 on each line). These seem to be all NT FTP servers, and while
12330 perhaps questionable, they appear to be legal by RFC 959.
12331 - Add missing kill_timeout() after transfer to user completes.
12334 *) Fixed problem where a busy server could hang when restarting
12335 after being sent a SIGHUP due to child processes not exiting.
12338 *) Modify mod_include escaping so a '\' only signifies an escaped
12339 character if the next character is one that needs
12340 escaping. [Ben Laurie]
12342 *) Eliminated possible infinite loop in mod_imap when relative URLs are
12343 used with a 'base' directive that does not have a '/' in it.
12344 [Marc Slemko, reported by Onno Witvliet <onno tc.hsa.nl>]
12346 *) Reduced the default timeout from 1200 seconds to 300, and the
12347 one in the sample configfile from 400 to 300. [Marc Slemko]
12349 *) Stop vbprintf from crashing if given a NULL string pointer;
12350 print (null) instead. [Ken Coar]
12352 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
12353 [Marc Slemko and Roy Fielding]
12355 *) Fixed problem with mod_cgi-generated internal redirects trying to
12356 read the request message-body twice. [Archie Cobbs and Roy Fielding]
12358 *) Reduced timeout on lingering close, removed possibility of a blocked
12359 read causing the child to hang, and stopped logging of errors if
12360 the socket is not connected (reset by client). [Roy Fielding]
12362 *) Rearranged main child loop to remove duplication of code in
12363 select/accept and keep-alive requests, fixed several bugs regarding
12364 checking scoreboard_image for exit indication and failure to
12365 account for all success conditions and trap all error conditions,
12366 prevented multiple flushes before closing the socket; close the entire
12367 socket buffer instead of just one descriptor, prevent logging of
12368 EPROTO and ECONNABORTED on platforms where supported, and generally
12369 improved readability. [Roy Fielding]
12371 *) Extensive performance improvements. Cleaned up inefficient use of
12372 auto initializers, multiple is_matchexp calls on a static string,
12373 and excessive merging of response_code_strings. [Dean Gaudet]
12375 *) Added double-buffering to mod_include to improve performance on
12376 server-side includes. [Marc Slemko]
12378 *) Several fixes for suexec wrapper. [Randy Terbush]
12379 - Make wrapper work for files on NFS filesystem.
12380 - Fix portability problem of MAXPATHLEN.
12381 - Fix array overrun problem in clean_env().
12382 - Fix allocation of PATH environment variable
12384 *) Removed extraneous blank line is description of mod_status chars.
12387 *) Logging of errors from the call_exec routine simply went nowhere,
12388 since the logfile fd has been closed, so now we send them to stderr.
12389 [Harald T. Alvestrand]
12391 *) Fixed core dump when DocumentRoot is a CGI.
12392 [Ben Laurie, reported by <geddis tesserae.com>]
12394 *) Fixed potential file descriptor leak in mod_asis; updated it and
12395 http_core to use pfopen/pfclose instead of fopen/fclose.
12396 [Randy Terbush and Roy Fielding]
12398 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
12399 as the DEC Alpha which is 64-bit but uses 32-bit ints.
12400 [Dean Gaudet and Ken Coar]
12402 *) Return a 302 response code to the client when sending a redirect
12403 due to a missing trailing '/' on a directory instead of a 301; now
12404 it is cacheable. [Markus Gyger]
12406 *) Fix condition where, if a bad directive occurs in .htaccess, and
12407 sub_request() goes first to this directory, then log_reason() will
12408 SIGSEGV because it doesn't have initialized r->per_dir_config.
12409 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
12411 *) Fix handling of lang_index in is_variant_better(). This was
12412 causing problems which resulted in the server sending the
12413 wrong language document in some cases. [Petr Lampa]
12415 *) Remove free() from clean_env() in suexec wrapper. This was nuking
12416 the clean environment on some systems.
12418 *) Tweak byteserving code (e.g. serving PDF files) to work around
12419 bugs in Netscape Navigator and Microsoft Internet Explorer.
12420 Emit Content-Length header when sending multipart/byteranges.
12423 *) Port to HI-UX/WE2. [Nick Maclaren]
12425 *) Port to HP MPE operating system for HP 3000 machines
12426 [Mark Bixby <markb cccd.edu>]
12428 *) Fixed bug which caused a segmentation fault if only one argument
12429 given to RLimit* directives. [Ed Korthof]
12431 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
12433 *) Improved buffered output to the client by delaying the flush decision
12434 until the BUFF code is actually about to read the next request.
12435 This fixes a problem introduced in 1.2b5 with clients that send
12436 an extra CRLF after a POST request. Also improved chunked output
12437 performance by combining writes using writev() and removing as
12438 many bflush() calls as possible. NOTE: Platforms without writev()
12439 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
12440 or Configure, unless we have already done so. [Dean Gaudet]
12442 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
12444 *) Fixed mod_info output corruption bug introduced by buffer overflow
12445 fixes. [Dean Gaudet]
12447 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
12448 for the special case of a 304 response. [Paul Sutton]
12450 *) Improved handling of TRACE method by bypassing normal method handling
12451 and header parsing routines; fixed Allow response to always allow TRACE.
12454 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
12456 *) Cleaned-up some of the generated HTML. [Ken Coar]
12458 Changes with Apache 1.2b6
12460 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
12462 *) Fix typo introduced in fix for potential infinite loop around
12463 accept() in child_main(). This change caused the rev to 1.2b6.
12464 1.2b5 was never a public beta.
12466 Changes with Apache 1.2b5
12468 *) Change KeepAlive semantics (On|Off instead of a number), add
12469 MaxKeepAliveRequests directive. [Alexei Kosut]
12471 *) Various NeXT compilation patches, as well as a change in
12472 regex/regcomp.c since that file also used a NEXT define.
12475 *) Allow * to terminate the end of a directory match in mod_dir.
12476 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
12478 *) Don't call can_exec() if suexec_enabled. Calling this requires
12479 scripts executed by the suexec wrapper to be world executable, which
12480 defeats one of the advantages of running the wrapper. [Randy Terbush]
12482 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
12485 *) Migration from sprintf() to snprintf() to avoid buffer
12486 overflows. [Marc Slemko]
12488 *) Provide portable snprintf() implementation (ap_snprintf)
12489 as well as *cvt family. [Jim Jagielski]
12491 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
12494 *) Remove mod_fastcgi.c from the distribution. This module appears
12495 to be maintained more through the Open Market channels and should
12496 continue to be easily available at http://www.fastcgi.com/
12498 *) Fixed bug in modules/Makefile that wouldn't allow building in more
12499 than one subdirectory (or cleaning, either). [Jeremy Laidman]
12501 *) mod_info assumed that the config files were relative to ServerRoot.
12504 *) CGI scripts called as an error document resulting from failed
12505 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
12507 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
12510 *) Properly check errno to prevent display of a directory index
12511 when server receives a long enough URL to confuse stat().
12514 *) Several security enhancements to suexec wrapper. It is _highly_
12515 recommended that previously installed versions of the wrapper
12516 be replaced with this version. [Randy Terbush, Jason Dour]
12518 - ~user execution now properly restricted to ~user's home
12519 directory and below.
12520 - execution restricted to UID/GID > 100
12521 - restrict passed environment to known variables
12522 - call setgid() before initgroups() (portability fix)
12523 - remove use of setenv() (portability fix)
12525 *) Add HTTP/1.0 response forcing. [Ben Laurie]
12527 *) Add access control via environment variables. [Ben Laurie]
12529 *) Add rflush() function. [Alexei Kosut]
12531 *) remove duplicate pcalloc() call in new_connection().
12533 *) Fix incorrect comparison which could allow number of children =
12534 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
12535 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
12537 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
12538 AIX PS/2, CONVEXOS. [Jim Jagielski]
12540 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
12541 It's more portable. [Martin Kraemer]
12543 *) Replace references to make in Makefile.tmpl with $(MAKE).
12546 *) Add ProxyBlock directive w/IP address caching. Add IP address
12547 caching to NoCache directive as well. ProxyBlock works with all
12548 handlers; NoCache now also works with FTP for anonymous logins.
12549 Still more code cleanup. [Chuck Murcko]
12551 *) Add "header parse" API hook [Ben Laurie]
12553 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
12555 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
12557 *) Correctly allow access and auth directives in <Files> sections in
12558 server config files. [Alexei Kosut]
12560 *) Fix bug with ServerPath that could cause certain files to be not
12561 found by the server. [Alexei Kosut]
12563 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
12564 double-quote from text and so that it properly checks for unsupported
12565 status codes using the new index_of_response interface. [Roy Fielding]
12567 *) Multiple fixes to the lingering_close code in order to avoid being
12568 interrupted by a stray timeout, to avoid lingering on a connection
12569 that has already been aborted or never really existed, to ensure that
12570 we stop lingering as soon as any error condition is received, and to
12571 prevent being stuck indefinitely if the read blocks. Also improves
12572 reporting of error conditions. [Marc Slemko and Roy Fielding]
12574 *) Fixed initialization of parameter structure for sigaction.
12575 [<mgyger itr.ch>, Adrian Filipi-Martin]
12577 *) Fixed reinitializing the parameters before each call to accept and
12578 select, and removed potential for infinite loop in accept.
12579 [Roy Fielding, after useful PR from <adrian virginia.edu>]
12581 *) Fixed condition where, if a child fails to fork, the scoreboard would
12582 continue to say SERVER_STARTING forever. Eventually, the main process
12583 would refuse to start new children because count_idle_servers() will
12584 count those SERVER_STARTING entries and will always report that there
12585 are enough idle servers. [Phillip Vandry]
12587 *) Fixed bug in bcwrite regarding failure to account for partial writes.
12588 Avoided calling bflush() when the client is pipelining requests.
12589 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
12591 *) Added description of "." mode in server-status [Jim Jagielski]
12593 Changes with Apache 1.2b4
12595 *) Fix possible race condition in accept_mutex_init() that
12596 could leave a small security hole open allowing files to be
12597 overwritten in cases where the server UID has write permissions.
12600 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
12602 *) Fix portablity problem in util_script where ARG_MAX may not be
12603 defined for some systems.
12605 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
12608 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
12609 style magic #! token for better script portability. [Garey Smiley]
12611 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
12612 execution for ~userdir CGI. [Jason Dour]
12614 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
12616 *) Fix month off by one in suexec wrapper logging.
12618 Changes with Apache 1.2b3:
12620 *) Fix error in mod_cgi which could cause resources not to be properly
12621 freed, or worse. [Dean Gaudet]
12623 *) Fix find_string() NULL pointer dereference. [Howard Fear]
12625 *) Add set_flag_slot() at the request of Dirk and others.
12628 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
12630 *) Add changes to improve the error message given for invalid
12631 ServerName parameters. [Dirk vanGulik]
12633 *) Add "Authoritative" directive for Auth modules that don't
12634 currently have it. This gives admin control to assign authoritative
12635 control to an authentication scheme and allow "fall through" for
12636 those authentication modules that aren't "Authoritative" thereby
12637 allowing multiple authentication mechanisms to be chained.
12640 *) Remove requirement for ResourceConfig/AccessConfig if not using
12641 the three config file layout. [Randy Terbush]
12643 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
12645 *) Changes to suexec wrapper to fix the following problems:
12646 1. symlinked homedirs will kill ~userdirs.
12647 2. initgroups() on Linux 2.0.x clobbers gr->grid.
12648 3. CGI command lines paramters problems
12649 4. pw-pwdir for "docroot check" still the httpd user's pw record.
12650 [Randy Terbush, Jason Dour]
12652 *) Change create_argv() to accept variable arguments. This fixes
12653 a problem where arguments were not getting passed to the CGI via
12654 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
12656 *) Collapse multiple slashes in path URLs to properly apply
12657 handlers defined by <Location>. [Alexei Kosut]
12659 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
12661 *) Improve the accuracy of request duration timings by setting
12662 r->request_time in read_request_line() instead of read_request().
12665 *) Reset timeout while reading via get_client_block() in mod_cgi.c
12666 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
12668 *) Add the ability to pass different Makefile.tmpl files to Configure
12669 using the -make flag. [Rob Hartill]
12671 *) Fix coredump triggered when sending a SIGHUP to the server caused
12672 by an assertion failure, in turn caused by an uninitialised field in a
12676 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
12677 PATH_INFO from previous versions of Apache (in certain situations,
12678 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
12679 [later removed in 1.2b11]
12681 *) Add rwrite() function to API to allow for sending strings of
12682 arbitrary length. [Doug MacEachern]
12684 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
12686 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
12687 NeXT. [Jim Jagielski]
12689 *) Removed recent modification to promote the status code on internal
12690 redirects, since the correct fix was to change the default log format
12691 in mod_log_config so that it outputs the original status. [Rob Hartill]
12693 Changes with Apache 1.2b2:
12695 *) Update set_signals() to use sigaction() for setting handlers.
12696 This appears to fix a re-entrant problem in the seg_fault()
12697 bus_error() handlers. [Randy Terbush]
12699 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
12701 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
12703 *) proxy_http.c bugfixes: [Chuck Murcko]
12704 1) fixes possible NULL pointer reference w/NoCache
12705 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
12706 host would cache nothing if it was in the local domain,
12707 and the local domain was in the NoCache list)
12708 3) Adds Host: header when not available
12709 4) Some code cleanup and clarification
12711 *) mod_include.c bugfixes:
12712 1) Fixed an ommission that caused include variables to not
12713 be parsed in config errmsg directives [Howard Fear]
12714 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
12715 3) Patch to fix compiler warnings [<perrot lal.in2p3.fr>]
12716 4) Allow backslash-escaping to all quoted text
12717 [Ben Yoshino <ben wiliki.eng.hawaii.edu>]
12718 5) Pass variable to command line if not set in XSSI's env
12721 *) Fix infinite loop when processing Content-language lines in
12722 type-map files. [Alexei Kosut]
12724 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
12726 *) Fixed problem in set_[user|group] that prevented CGI execution
12727 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
12729 *) Added PORTING information file. [Jim Jagielski]
12731 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
12733 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
12735 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
12736 USE_FCNTL_SERIALIZED_ACCEPT was intended.
12738 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
12739 which caused problems of systems where socket s_addr is >32bits.
12741 *) Added comment to explain (r->chunked = 1) side-effect in
12742 http_protocol.c [Roy Fielding]
12744 *) Replaced use of index() in mod_expires.c with more appropriate
12745 and portable isdigit() test. [Ben Laurie]
12747 *) Updated Configure for ...
12748 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
12749 *-dg-dgux* (bad pattern match)
12750 QNX (DEF_WANTHSREGEX=yes)
12751 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
12753 *-unixware211 (new)
12754 and added some user diagnostic info. [Ben Laurie]
12756 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
12757 for better portability. [Jim Jagielski]
12759 *) Updated helpers/GuessOS for ...
12760 SCO 5 (recognize minor releases)
12761 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
12762 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
12763 IRIX64 (-sgi-irix64)
12764 ULTRIX (-unknown-ultrix)
12765 SINIX (-whatever-sysv4)
12766 NCR Unix (-ncr-sysv4)
12767 and fixed something in helpers/PrintPath [Ben Laurie]
12769 Changes with Apache 1.2b1
12771 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
12773 Changes with Apache 1.1.1
12775 *) Fixed bug where Cookie module would make two entries in the
12776 logfile for each access [Mark Cox]
12778 *) Fixed bug where Redirect in .htaccess files would cause memory
12779 leak. [Nathan Neulinger]
12781 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
12783 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
12785 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
12787 Changes with Apache 1.1.0
12789 *) Bring NeXT support up to date. [Takaaki Matsumoto]
12791 *) Bring QNX support up to date. [Ben Laurie]
12793 *) Make virtual hosts default to main server keepalive parameters.
12794 [Alexei Kosut, Ben Laurie]
12796 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
12798 *) Fix missing address family for connect, also remove unreachable statement
12799 in mod_proxy. [Ben Laurie]
12801 *) mod_env now turned on by default in Configuration.tmpl.
12803 *) Bugs which were fixed:
12804 a) yet more mod_proxy bugs [Ben Laurie]
12805 b) CGI works again with inetd [Alexei Kosut]
12806 c) Leading colons were stripped from passwords [<osm interguide.com>]
12807 d) Another fix to multi-method Limit problem [<jk tools.de>]
12809 Changes with Apache 1.1b4
12811 *) r->bytes_sent variable restored. [Robert Thau]
12813 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
12815 *) More possibly unsecure programs removed from the support directory.
12817 *) More mod_auth_msql authentication improvements.
12819 *) VirtualHosts based on Host: headers no longer conflict with the
12822 *) OS/2 compatibility enhancements. [Gary Smiley]
12824 *) POST now allowed to directory index CGI scripts.
12826 *) Actions now work with files of the default type.
12828 *) Bugs which were fixed:
12829 a) more mod_proxy bugs
12830 b) early termination of inetd requests
12831 c) compile warnings on several systems
12832 d) problems when scripts stop reading output early
12834 Changes with Apache 1.1b3
12836 *) Much of cgi-bin and all of cgi-src has been removed, due to
12837 various security holes found and that we could no longer support
12840 *) The "Set-Cookie" header is now special-cased to not merge multiple
12841 instances, since certain popular browsers can not handle multiple
12842 Set-Cookie instructions in a single header. [Paul Sutton]
12844 *) rprintf() added to buffer code, occurrences of sprintf removed.
12847 *) CONNECT method for proxy module, which means tunneling SSL should work.
12848 (No crypto needed) Also a NoCache config directive.
12850 *) Several API additions: pstrndup(), table_unset() and get_token()
12851 functions now available to modules.
12853 *) mod_imap fixups, in particular Location: headers are now complete
12856 *) New "info" module which reports on installed module set through a
12857 special URL, a la mod_status.
12859 *) "ServerPath" directive added - allows for graceful transition
12860 for Host:-header-based virtual hosts.
12862 *) Anonymous authentication module improvements.
12864 *) MSQL authentication module improvements.
12866 *) Status module design improved - output now table-based. [Ben Laurie]
12868 *) htdigest utility included for use with digest authentication
12871 *) mod_negotiation: Accept values with wildcards to be treated with
12872 less priority than those without wildcards at the same quality
12873 value. [Alexei Kosut]
12875 *) Bugs which were fixed:
12876 a) numerous mod_proxy bugs
12877 b) CGI early-termination bug [Ben Laurie]
12878 c) Keepalives not working with virtual hosts
12879 d) RefererIgnore problems
12880 e) closing fd's twice in mod_include (causing core dumps on
12881 Linux and elsewhere).
12883 Changes with Apache 1.1b2
12886 a) core dumps in mod_digest
12887 b) truncated hostnames/ip address in the logs
12888 c) relative URL's in mod_imap map files
12890 Changes with Apache 1.1b1
12892 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
12894 Changes with Apache 1.0.3
12896 *) Internal redirects which occur in mod_dir.c now preserve the
12897 query portion of a request (the bit after the question mark).
12900 *) Escape active characters '<', '>' and '&' in html output in
12901 directory listings, error messages and redirection links.
12904 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
12906 *) Fix for POSIX compliance in waiting for processes in alloc.c.
12909 *) setsockopt no longer takes a const declared argument [Martijn Koster]
12911 *) Reset timeout timer after each successful fwrite() to the network.
12912 This patch adds a reset_timeout() procedure that is called by
12913 send_fd() to reset the timeout ever time data is written to the net.
12916 *) timeout() signal handler now checks for SIGPIPE and reports
12917 lost connections in a more user friendly way. [Rob Hartill]
12919 *) Location of the "scoreboard" file which used to live in /tmp is
12920 now configurable (for OSes that can't use mmap) via ScoreBoardFile
12921 which works similar to PidFile (in httpd.conf) [Rob Hartill]
12923 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
12925 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
12926 which caused a SEGV with cookies enabled
12928 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
12931 *) Log the UNIX textual error returned by some system calls, in
12932 particular errors from accept() [David Robinson]
12934 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
12936 Changes with Apache 1.0.2
12938 *) patch to get Apache compiled on UnixWare 2.x, recommended as
12939 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
12941 *) Fix get_basic_auth_pw() to set the auth_type of the request.
12944 *) past changes to http_config.c to only use the
12945 setrlimit function on systems defining RLIMIT_NOFILE
12946 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
12947 for SUNOS and prototypes the needed functions.
12949 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
12952 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
12954 *) Merge multiple headers from CGI scripts instead of taking last
12955 one. [David Robinson]
12957 *) Add support for SCO 5. [Ben Laurie]
12959 Changes with Apache 1.0.1
12961 *) Silence mod_log_referer and mod_log_agent if not configured
12964 *) Recursive includes can occur if the client supplies PATH_INFO data
12965 and the server provider uses relative links; as file.html
12966 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
12968 *) The replacement for initgroups() did not call {set,end}grent(). This
12969 had two implications: if anything else used getgrent(), then
12970 initgroups() would fail, and it was consuming a file descriptor.
12973 *) On heavily loaded servers it was possible for the scoreboard to get
12974 out of sync with reality, as a result of a race condition.
12975 The observed symptoms are far more Apaches running than should
12976 be, and heavy system loads, generally followed by catastrophic
12977 system failure. [Ben Laurie]
12979 *) Fix typo in license. [David Robinson]
12981 Changes with Apache 1.0.0 23 Nov 1995
12983 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
12985 Changes with Apache 0.8.16 05 Nov 1995
12987 *) New man page for 'httpd' added to support directory [David Robinson]
12989 *) .htgroup files can have more than one line giving members for a
12990 given group (each must have the group name in front), for NCSA
12991 back-compatibility [Robert Thau]
12993 *) Mutual exclusion around accept() is on by default for SVR4 systems
12994 generally, since they generally can't handle multiple processes in
12995 accept() on the same socket. This should cure flaky behavior on
12996 a lot of those systems. [David Robinson]
12998 *) AddType, AddEncoding, and AddLanguage directives take multiple
12999 extensions on a single command line [David Robinson]
13001 *) UserDir can be disabled for a given virtual host by saying
13002 "UserDir disabled" in the <VirtualHost> section --- it was a bug
13003 that this didn't work. [David Robinson]
13005 *) Compiles on QNX [Ben Laurie]
13007 *) Corrected parsing of ctime time format [David Robinson]
13009 *) httpd does a perror() before exiting if it can't log its pid
13010 to the PidFile, to make diagnosing the error a bit easier.
13013 *) <!--#include file="..."--> can no longer include files in the
13014 parent directory, for NCSA back-compatibility. [David Robinson]
13016 *) '~' is *not* escaped in URIs generated for directory listings
13019 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
13021 *) Fixed bug involving handling URIs with escaped %-characters
13022 in redirects [David Robinson]
13024 Changes with Apache 0.8.15 14 Oct 1995
13026 *) Switched to new, simpler license
13028 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
13030 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
13032 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
13034 *) Correctly handles internal redirects to files with names containing '%'
13037 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
13039 *) Use geteuid() rather than getuid() to see if we have root privilege,
13040 so that server correctly resets privilege if run setuid root. [Andrew
13043 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
13046 *) Fix relative URLs in imagemap files [Randy Terbush]
13048 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
13051 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
13052 entries all name the same one. [David Robinson]
13054 *) Fix directory listings with filenames containing unusual characters
13057 *) Better URI-escaping for generated URIs in directories with filenames
13058 containing unusual characters [Ben Laurie]
13060 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
13062 *) Unblock alarms on error return from spawn_child() [David Robinson]
13064 *) Sample Config files have extra note for SCO users [Ben Laurie]
13066 *) Configuration has note for HP-UX users [Rob Hartill]
13068 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
13070 *) Nuked bogus #define in httpd.h [David Robinson]
13072 *) Better test for whether a system has setrlimit() [David Robinson]
13074 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
13076 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
13079 Changes with Apache 0.8.14 19 Sep 1995
13081 *) Compiles on SCO ODT 3.0 [Ben Laurie]
13083 *) AddDescription works (better) [Ben Laurie]
13085 *) Leaves an intelligible error diagnostic when it can't set group
13086 privileges on standalone startup [Andrew Wilson]
13088 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
13089 that machine, which claims to be BSD but does not support RLIMIT.
13092 *) gcc -Wall no longer complains about an unused variable when util.c
13093 is compiled with -DMINIMAL_DNS [Andrew Wilson]
13095 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
13097 Changes with Apache 0.8.13 07 Sep 1995
13099 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
13101 *) Have built-in imagemap code recognize & honor Point directive [James
13104 *) Generate cleaner directory listings in directories with a mix of
13105 long and short filenames [Rob Hartill]
13107 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
13109 *) Properly default ServerName for virtual servers [Robert Thau]
13111 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
13112 Paul Richards and a cast of thousands...]
13114 *) On self-identified BSD systems (we don't try to guess any more),
13115 allocate a few extra file descriptors per virtual host with setrlimit,
13116 if we can, to avoid running out. [Randy Terbush]
13118 *) Write 22-character lock file name into buffer with enough space
13119 on startup [Konstantin Olchanski]
13121 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
13124 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
13126 *) Suppress -Wall warning by initializing variable in negotiation code
13127 [Tobias Weingartner]
13129 Changes with Apache 0.8.12 31 Aug 1995
13131 *) Doesn't pause three seconds after including a CGI script which is
13132 too slow to die off (this is done by not even trying to kill off
13133 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
13134 after the entire document has been processed). [Robert Thau]
13136 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
13138 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
13140 *) Allows .htaccess files to override <Directory> sections naming the
13141 same directory [David Robinson]
13143 *) Removed an efficiency hack in sub_req_lookup_uri which was
13144 causing certain extremely marginal cases (e.g., ScriptAlias of a
13145 *particular* index.html file) to fail. [David Robinson]
13147 *) Doesn't log an error when the requested URI requires
13148 authentication, but no auth header line was supplied by the
13149 client; this is a normal condition (the client doesn't no auth is
13150 needed here yet). [Robert Thau]
13152 *) Behaves more sanely when the name server loses its mind [Sean Welch]
13154 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
13156 *) RFC931 code no longer passes out name of prior clients on current
13157 requests if the current request came from a server that doesn't
13158 do RFC931. [David Robinson]
13160 *) Configuration script accepts "Module" lines with trailing whitespace.
13163 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
13165 *) Cleaned up comments in mod_cgi.c [Robert Thau]
13167 Changes with Apache 0.8.11 24 Aug 1995
13169 *) Wildcard <Directory> specifications work. [Robert Thau]
13171 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
13173 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
13174 the file being requested itself, in addition to the directories leading
13175 up to it. [Robert Thau]
13177 *) Logs access failures due to symlink checks or invalid client address
13178 in the error log [Roy Fielding, Robert Thau]
13180 *) Symlink checks deal correctly with systems where lstat of
13181 "/path/to/some/link/" follows the link. [Thau, Fielding]
13183 *) Doesn't reset DirectoryIndex to 'index.html' when
13184 other directory options are set in a .htaccess file. [Robert Thau]
13186 *) Clarified init code and nuked bogus warning in mod_access.c
13187 [Florent Guillaume]
13189 *) Corrected several directives in sample srm.conf
13190 --- includes corrections to directory indexing icon-related directives
13191 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
13192 icons for encodings right, and turning on AddEncoding by default).
13195 *) Corrected descriptions of args to AddIcon and AddAlt in command table
13198 *) INSTALL & README mention "contributed modules" directory [Brian
13201 *) Fixed English in the license language... "for for" --> "for".
13204 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
13205 mod_alias.c, merging it almost completely with handling of Alias, and
13206 adding a 'notes' field to the request_rec which allows the CGI module
13207 to discover whether the Alias module has put this request through
13208 ScriptAlias (which it needs to know for back-compatibility, as the old
13209 NCSA code did not check Options ExecCGI in ScriptAlias directories).
13212 Changes with Apache 0.8.10 18 Aug 1995
13214 *) AllowOverride applies to the named directory, and not just
13215 subdirectories. [David Robinson]
13217 *) Do locking for accept() exclusion (on systems that need it)
13218 using a special file created for the purpose in /usr/tmp, and
13219 not the error log; using the error log causes real problems
13220 if it's NFS-mounted; this is known to be the cause of a whole
13221 lot of "server hang" problems with Solaris. [David Robinson;
13222 thanks to Merten Schumann for help diagnosing the problem].
13224 Changes with Apache 0.8.9 12 Aug 1995
13226 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
13228 *) Nested includes see environment variables of the including document,
13229 for NCSA bug-compatibility (some sites have standard footer includes
13230 which try to print out the last-modified date). [Eric Hagberg/Robert
13233 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
13234 URI as a CGI script, even if it would have been treated as something
13235 else if requested directly, for NCSA back-compatibility. (Note that
13236 this means that people who know the name of the script can see the
13237 code just by asking for it). [Robert Thau]
13239 *) New version of dbmmanage script included in support directory as
13242 *) Check if scoreboard file couldn't be opened, and say so, rather
13243 then going insane [David Robinson]
13245 *) POST to CGI works on A/UX [Jim Jagielski]
13247 *) AddIcon and AddAlt commands work properly [Rob Hartill]
13249 *) NCSA server push works properly --- the Arena bug compatibility
13250 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
13251 if you still want the workaround). [Rob Hartill]
13253 *) If client didn't submit any Accept-encodings, ignore encodings in
13254 content negotiation. (NB this will all have to be reworked anyway
13255 for the new HTTP draft). [Florent Guillaume]
13257 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
13259 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
13261 *) Give Redirect priority over Alias, for NCSA bug compatibility
13264 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
13265 paralleling earlier bug fix for CGI [David Robinson]
13267 *) If DBM auth is improperly configured, report a server error and don't
13270 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
13271 it seems to work well enough without it (even in a 10 hits/sec
13272 workout), and the overhead for the locking under A/UX is
13273 alarmingly high (though it is very low on other systems).
13274 [Eric Hagberg, Jim Jagielski]
13276 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
13278 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
13279 Behlendorf/Eric Hagberg]
13281 *) More improvements to default Configuration for A/UX [Jim Jagielski]
13283 *) Compiles clean on NEXT [Rob Hartill]
13285 *) Compiles clean on SGI [Robert Thau]
13287 Changes with Apache 0.8.8 08 Aug 1995
13289 *) SunOS library prototypes now never included unless explicitly
13290 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
13291 people using GNU libc on SunOS are screwed by prototypes for the
13294 (Those who wish to compile clean with gcc -Wall on a standard
13295 SunOS setup need the prototypes, and may obtain them using
13296 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
13297 with nonstandard libraries are presumably competent to make their
13300 *) Strips trailing '/' characters off both args to the Alias command,
13301 to make 'Alias /foo/ /bar/' work.
13303 Changes with Apache 0.8.7 03 Aug 1995
13305 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
13306 [reported by David Robinson]
13308 *) Compiles clean on OSF/1 [David Robinson]
13310 *) Added some of the more recent significant changes (AddLanguage stuff,
13311 experimental LogFormat support) to CHANGES file in distribution root
13314 Changes with Apache 0.8.6 02 Aug 1995
13316 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
13317 (If you actually wanted a conditional GET which bypassed the cache, you
13318 couldn't get it). [Reported by Roy Fielding]
13320 *) Properly terminate headers on '304 Not Modified' replies to conditional
13321 GETs --- no browser we can find cares much, but the CERN proxy chokes.
13322 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
13324 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
13326 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
13327 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
13328 and older versions don't set the __SUNPRO_C preprocessor variable). On
13329 all other systems, these are never used anyway. [Reported by Mark Cox].
13331 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
13333 Changes with Apache 0.8.5 01 Aug 1995
13335 *) Added last-minute configurable log experiment, as optional module
13337 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
13338 properly. (One-line fix to http_protocol.c).
13340 *) Work around bogus behavior when reloading from Netscape.
13341 It's Netscape's bug --- for some reason they expect a request with
13342 If-modified-since: to not function as a conditional GET if it also
13343 comes with Pragma: no-cache, which is way out of line with the HTTP
13344 spec (according to Roy Fielding, the redactor).
13346 *) Added parameter to set maximum number of server processes.
13348 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
13351 *) IdentityCheck bugfix [Chuck Murcko].
13353 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
13355 *) More sample config file corrections; add extension to AddType for
13356 *.asis, move AddType generic description to its proper place, and
13357 fix miscellaneous typos. [ Alexei Kosut ]
13359 *) Deleted the *other* reference to the regents from the Berkeley
13360 legal disclaimer (everyplace).
13362 *) Nuked Shambhala name from src/README; had already cleaned it out
13363 of everywhere else.
13365 Changes with Apache 0.8.4
13367 *) Changes to server-pool management parms --- renamed current
13368 StartServers to MinSpareServers, created separate StartServers
13369 parameter which means what it says, and renamed MaxServers to
13370 MaxSpareServers (though the old name still works, for NCSA 1.4
13371 back-compatibility). The old names were generally regarded as
13372 too confusing. Also altered "docs" in sample config files.
13374 *) More improvements to default config files ---
13375 sample directives (commented out) for XBitHack, BindAddress,
13376 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
13377 defaults, AddTypes for send-as-is and imagemap magic types, and
13378 improvements to samples for DirectoryIndex [Alexei Kosut]
13380 *) Yet more improvements to default config files --- changes to
13381 Alexei's sample AddLanguage directives, and sample LanguagePriority
13382 [ Florent Guillaume ]
13384 *) Set config file locations properly if not set in httpd.conf
13387 *) Don't escape URIs in internal redirects multiple times; don't
13388 do that when translating PATH_INFO to PATH_TRANSLATED either.
13391 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
13393 Changes with Apache 0.8.3
13395 *) Edited distribution README to *briefly* summarize installation
13396 procedures, and give a pointer to the INSTALL file in the src/
13399 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
13400 recent NCSA distributions.
13402 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
13403 exist for the same directory, use both and don't segfault. [Reported
13406 *) Proper makefile dependencies [David Robinson]
13408 *) Note (re)starts in error log --- reported by Rob Hartill.
13410 *) Only call no2slash() after get_path_info() has been done, to
13411 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
13412 reported by Andrew Wilson, though this one is probably a real bug]
13414 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
13415 dump core when Referer is not supplied. [Randy Terbush]
13417 *) Lightly edited sample config files to refer people to our documentation
13418 instead of NCSA's, and to list Rob McCool as *original* author (also
13419 deleted his old, and no doubt non-functional email address). Would be
13420 nice to have examples of new features...
13422 Changes with Apache 0.8.2 19 Jul 1995
13424 *) Added AddLanuage code [Florent Guillaume]
13426 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
13428 *) All sorts of problems when MultiViews finds a directory. It would
13429 be nice if mod_dir.c was robust enough to handle that, but for now,
13430 just punt. [reported by Brian Behlendorf]
13432 *) Wait for all children on restart, to make sure that the old socket
13433 is gone and we can reopen it. [reported by Randy Terbush]
13435 *) Imagemap module is enabled in default Configuration
13437 *) RefererLog and UserAgentLog modules properly default the logfile
13440 *) Mark Cox's mod_cookies added to the distribution as an optional
13441 module (commented out in the default Configuration, and noted as
13442 an experiment, along with mod_dld). [Mark Cox]
13444 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
13446 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
13448 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
13450 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
13453 Changes with Apache 0.8.1
13455 *) New imagemap module [Randy Terbush]
13457 *) Replacement referer log module with NCSA-compatible RefererIgnore
13458 [Matthew Gray again]
13460 *) Don't mung directory listings with very long filenames.
13461 [Florent Guillaume]
13463 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
13465 *) New config script. See INSTALL for info. [Robert Thau]
13467 *) Scoreboard mechanism for regulating the number of extant server
13468 processes. MaxServers and StartServers defaults are the same as
13469 for NCSA, but the meanings are slightly different. (Actually,
13470 I should probably lower the MaxServers default to 10).
13472 Before asking for a new connection, each server process checks
13473 the number of other servers which are also waiting for a
13474 connection. If there are more than MaxServers, it quietly dies
13475 off. Conversely, every second, the root, or caretaker, process
13476 looks to see how many servers are waiting for a new connection;
13477 if there are fewer than StartServers, it starts a new one. This
13478 does not depend on the number of server processes already extant.
13479 The accounting is arranged through a "scoreboard" file, named
13480 /tmp/htstatus.*, on which each process has an independent file
13481 descriptor (they need to seek without interference).
13483 The end effect is that MaxServers is the maximum number of
13484 servers on an *inactive* server machine, but more will be forked
13485 off to handle unusually heavy loads (or unusually slow clients);
13486 these will die off when they are no longer needed --- without
13487 reverting to the overhead of full forking operation. There is a
13488 hard maximum of 150 server processes compiled in, largely to
13489 avoid forking out of control and dragging the machine down.
13490 (This is arguably too high).
13492 In my server endurance tests, this mechanism did not appear to
13493 impose any significant overhead, even after I forced it to put the
13494 scoreboard file on a normal filesystem (which might have more
13495 overhead than tmpfs). [Robert Thau]
13497 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
13500 *) Read .htaccess files even in directory with <Directory> section.
13501 (Former incompatibility noted on mailing list, now fixed). [Robert
13504 *) "HEAD /" gives the client a "Bad Request" error message, rather
13505 than trying to send no body *and* no headers. [Cliff Skolnick].
13507 *) Don't produce double error reports for some very obscure cases
13508 mainly involving auth configuration (the "all modules decline to
13509 handle" case which is a sure sign of a server bug in most cases,
13510 but also happens when authentication is badly misconfigured).
13513 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
13514 it's *for*, and this sort of thing really shouldn't be cluttering
13515 up the Makefile). [Robert Thau]
13517 *) Incidental code cleanups in http_main.c --- stop dragging
13518 sa_client around; just declare it where used. [Robert Thau]
13520 *) Another acc-related fix. (It doesn't like const char
13521 in some places...). [Mark Cox]
13523 Changes with Shambhala 0.6.1 13 Jul 1995
13525 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
13526 Also, fixed auth typo in http_protocol.c unmasked by this fix.
13528 *) Compiles clean with acc on SunOS [Paul Sutton]
13530 *) Reordered modules in modules.c so that Redirect takes priority
13531 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
13532 believe it or not, he has an actual site with a ScriptAlias and
13533 a Redirect declared for the *exact same directory*. Even *my*
13534 compatibility fetish wouldn't motivate me to fix this if the fix
13535 required any effort, but it doesn't, so what the hey.
13537 *) Fixed to properly default several server_rec fields for virtual
13538 servers from the corresponding fields in the main server_rec.
13539 [Cliff Skolnick --- 'port' was a particular irritant].
13541 *) No longer kills off nph- child processes before they are
13542 finished sending output. [Matthew Gray]
13544 Changes with Shambhala 0.6.0 10 Jul 1995
13546 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
13547 the connection to the client in an "aborted" state, but otherwise
13548 allow whatever handlers are running to clean up. hard_timeout()s
13549 abort the request in progress completely; anything not tied to some
13550 resource pool cleanup will leak. They're still around because I
13551 haven't yet come up with a more elegant way of handling
13552 timeouts when talking to something that isn't the client. The
13553 default_handler and the dir_handler now use soft timeouts, largely
13554 so I can test the feature. [Robert Thau]
13556 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
13557 the case of log handlers dying prematurely is probably handled VERY
13558 gracelessly at this point, and if the logger stops reading input,
13559 the server will hang. (It is known to correctly restart the
13560 logging process on server restart; this is (should be!) going through
13561 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
13562 script). [Robert Thau]
13564 *) asis files supported (new module). [Robert Thau]
13566 *) IdentityCheck code is compiled in, but has not been tested. (I
13567 don't know anyone who runs identd). [Robert Thau]
13569 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
13570 came in with the request, for NCSA bug-compatibility. [Robert Thau]
13572 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
13574 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
13575 as timeouts are not in scope. [Robert Thau]
13577 *) quoted-string args in config files now handled correctly (doesn't drop
13578 the last character). [Robert Thau; reported by Randy Terbush]
13580 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
13581 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
13583 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
13584 default default type); the former default default behavior when all
13585 type-checkers defaulted had been a core dump. [Paul Sutton]
13587 *) Copy filenames out of the struct dirent when indexing
13588 directories. (On Linux, readdir() returns a pointer to the same
13589 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
13591 Changes with Shambhala 0.5.3 [not released]
13593 *) Default response handler notes "file not found" in the error log,
13594 if the file was not found. [Cliff Skolnick].
13596 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
13597 code no longer sets up bogus PATH_INFO which fakes out the directory
13598 handler). [Cliff Skolnick]
13600 Changes with Shambhala 0.5.2 06 Jul 1995
13602 *) Changes to http_main.c --- root server no longer plays silly
13603 games with SIGCHLD, and so now detects and replaces dying
13604 children. Child processes just die on SIGTERM, without taking
13605 the whole process group with them. Potential problem --- if any
13606 child process refuses to die, we hang in restart.
13607 MaxRequestsPerChild may still not work, but it certainly works
13608 better than it did before this! [Robert Thau]
13610 *) mod_dir.c bug fixes: ReadmeName and HeaderName
13611 work (or work better, at least); over-long description lines
13612 properly terminated. [Mark Cox]
13614 *) http_request.c now calls unescape_url() more places where it
13615 should [Paul Sutton].
13617 *) More directory handling bugs (reported by Cox)
13618 Parent Directory link is now set correctly. [Robert Thau]
13620 Changes with Shambhala 0.5.1 04 Jul 1995
13622 *) Generalized cleanup interface in alloc.c --- any function can be
13623 registered with alloc.c as a cleanup for a resource pool;
13624 tracking of files and file descriptors has been reimplemented in
13625 terms of this interface, so I can give it some sort of a test.
13628 *) More changes in alloc.c --- new cleanup_for_exec() function,
13629 which tracks down and closes all file descriptors which have been
13630 registered with the alloc.c machinery before the server exec()s a
13631 child process for CGI or <!--#exec-->. CGI children now get
13632 started with exactly three file descriptors open. Hopefully,
13633 this cures the problem Rob H. was having with overly persistent
13634 CGI connections. [Robert Thau]
13636 *) Mutual exclusion around the accept() in child_main() --- this is
13637 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
13638 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
13639 This uses fcntl(F_SETLK,...) on the error log descriptor because
13640 flock() on that descriptor won't work on systems which have BSD
13641 flock() semantics, including (I think) Linux 1.3 and Solaris.
13643 This does work on SunOS (when the server is idle, only one
13644 process in the pool is waiting on accept()); it *ought* to work
13645 on the other systems. [Robert Thau]
13647 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
13649 *) sizeof(*sa_client) bugfix from [Rob Hartill]
13651 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
13653 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
13654 be unnecessary if I go to the revised timeout-handling scheme).
13657 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
13658 string) even if none came in with the request. [Robert Thau]
13660 *) CHANGES file added to distribution ;-).
13662 Changes with Shambhala 0.4.5
13664 *) mod_dld --- early dynamic loading support [rst]
13665 *) Add wildcard content handlers for XBITHACK; default_hander now
13666 invoked with that mechanism (as a handler hanging off mod_core) [rst]
13667 *) XBITHACK supported as a wildcard content-handler, and
13668 configurable at run-time (not just at compile time, as in the
13669 "patchy server" releases) [rst]
13671 Changes with Shambhala 0.4.4 30 Jun 1995
13673 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
13674 *) Handle Addtype x/y .z [rst, reported by Cox]
13676 Changes with Shambhala 0.4.3
13678 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
13679 synonymous [rst, terbush]
13681 Changes with Shambhala 0.4.1 28 Jun 1995
13683 *) First-cut virtual host implementation; some refit in the config
13684 reading code, and log management, was necessary to support this [rst]
13685 *) Sub-pool machinery, originally added to avoid excessive storage
13686 allocation on listings of large directories (which turned out to
13687 be the problem that the 0.3 storage accounting was added to
13688 find). Subrequests and mod_dir changed to use subpools. [rst]
13689 *) More memory debugging --- free list consistency checks. [rst]
13690 *) Added err_headers to request_rec, with support elsewhere [rst]
13691 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
13693 Changes with Shambhala 0.3 19 Jun 1995
13695 *) Switch ONE_PROCESS to a runtime command-line option (-X)
13696 *) Don't compile in mod_ai_backcompat by default
13697 *) Switch name of server from Apache to Shambhala in Makefile
13698 *) Add some accounting routines to track memory usage in the pools,
13701 Changes with Shambhala 0.2
13703 *) Set DOCUMENT_ROOT CGI variable
13704 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
13705 *) Add critical section protection to handling of cleanup structures
13707 *) Significant code reorg within the server core to group related
13708 functions together [rst]
13709 *) Correctly handle clients that hang up before sending any request
13711 *) Replace dying child processes. [rst]
13713 Changes with Shambhala 0.1 12 Jun 1995
13715 Major rewrite of the pre-existing "patchy server" codebase, by
13716 Robert Thau (rst). Significant portions of the server code, such
13717 as configuration-file handling and HTTP authentication support,
13718 were ripped out and rewritten from scratch. Code that was not
13719 completely rewritten was significantly altered.
13721 Major changes with this release include:
13723 *) Introduction of the module API; in request handling, the central
13724 machinery just dispatches to various modules, which actually do
13725 most of the work. Configuration handling is similar --- modules
13726 declare their own commands, and the central machinery just
13727 dispatches to them.
13729 API features from shambhala/0.1 were substantially unchanged in
13730 Apache 1.0 and 1.1. (1.0 API features not yet present in this
13731 release, such as wildcard handlers and subpools, were added in
13732 subsequent Shambhala releases, and were also generally rst's
13735 *) This release included the following modules:
13737 mod_access (access control --- allow and deny directives),
13738 mod_alias (Alias and Redirect commands),
13739 mod_auth (straight HTTP authentication, based on flat-files)
13740 mod_auth_dbm (same, with dbm files)
13741 mod_cgi (CGI scripts and, in this release, ScriptAlias)
13742 mod_common_log (CLF access logs; later renamed mod_log_common)
13743 mod_dir (directory indexing)
13744 mod_include (server-side includes)
13745 mod_mime (AddType directives)
13746 mod_negotiation (content negotiation)
13747 mod_userdir (support for users' public_html directories)
13749 It also included a mod_ai_backcompat, which was a private hack
13750 for back-compatibility with rst's own AI-lab servers.
13752 All of these modules were substantially complete, and functional
13753 or nearly so (a few, which implemented features not in use at
13754 Thau's site, required patches of a few lines).
13756 *) sub-request machinery, to allow modules to determine how other
13757 modules would assign MIME types to a given file, or optionally
13758 serve its content (this is heavily used by mod_dir, mod_include
13759 and mod_negotiation).
13761 *) Resource pool system for keeping track of memory allocated and
13762 files opened in service of a particular request. Much of the
13763 code in the modules (when they weren't rewrites) was adjusted to
13764 replace a pervasive convention of using fixed-size buffers on
13765 the stack with an equally pervasive convention of using memory
13766 allocated with palloc().
13768 *) Reorganization of data structures associated with a given
13769 request to eliminate use of global variables and the troublesome
13770 unmunge_name function (used in NCSA and early Apache releases to
13771 attempt to determine the URI which mapped to a given filename
13772 --- a difficult proposition, given that it is easy to produce
13773 setups in which multiple URIs map to the same file).
13775 *) Source files renamed and rearranged
13777 *) Very simple pre-forking behavior --- parent process forked off a
13778 fixed number of children, and then just waited for SIGHUP.
13780 *) Other more minor changes too numerous to list.
13782 This release included modified versions of a lot of code from the
13783 Apache 0.6.4 public release, plus an early pre-forking patch
13784 codeveloped by Robert Thau and Rob Hartill.
13786 Changes with Apache 0.7.3 20 Jun 1995
13788 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
13789 were incorporated by Rob Hartill on the main branch while Robert Thau
13790 worked on the Shambhala rewrite above. Most were merged into the
13791 Shambala architecture after Apache 0.8.0.
13793 Changes with Apache 0.6.4 13 May 1995
13795 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
13798 Changes with Apache 0.5.1 10 Apr 1995
13800 Changes with Apache 0.4 02 Apr 1995
13802 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
13805 Changes with Apache 0.3 24 Mar 1995
13807 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
13810 Changes with Apache 0.2 18 Mar 1995
13812 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
13813 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
13814 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
