[Apache httpd group]
*) Protect logresolve from mismanaged DNS records that return
blank/null hostnames. [Jim Jagielski]
Changes with Apache 1.3.41
*) SECURITY: CVE-2007-6388 (cve.mitre.org)
mod_status: Ensure refresh parameter is numeric to prevent
a possible XSS attack caused by redirecting to other URLs.
Reported by SecurityReason. [Mark Cox]
Changes with Apache 1.3.40 (not released)
*) SECURITY: CVE-2007-5000 (cve.mitre.org)
mod_imap: Fix cross-site scripting issue. Reported by JPCERT.
[Joe Orton]
*) SECURITY: CVE-2007-3847 (cve.mitre.org)
mod_proxy: Prevent reading past the end of a buffer when parsing
date-related headers. PR 41144.
With Apache 1.3, the denial of service vulnerability applies only
to the Windows and NetWare platforms.
[Jeff Trawick]
*) More efficient implementation of the CVE-2007-3304 PID table
patch. This fixes issues with excessive memory usage by the
parent process if long-running and with a high number of child
process forks during that timeframe. Also fixes bogus "Bad pid"
errors. [Jim Jagielski, Jeff Trawick]
Changes with Apache 1.3.39
*) SECURITY: CVE-2006-5752 (cve.mitre.org)
mod_status: Fix a possible XSS attack against a site with a public
server-status page and ExtendedStatus enabled, for browsers which
perform charset "detection". Reported by Stefan Esser. [Joe Orton]
*) SECURITY: CVE-2007-3304 (cve.mitre.org)
Ensure that the parent process cannot be forced to kill non-child
processes by checking scoreboard PID data with parent process
privately stored PID data. [Jim Jagielski]
*) mime.types: Many updates to sync with IANA registry and common
unregistered types that the owners refuse to register. Admins
are encouraged to update their installed mime.types file.
PR: 35550, 37798, 39317, 31483 [Roy T. Fielding]
There was no Apache 1.3.38
Changes with Apache 1.3.37
*) SECURITY: CVE-2006-3747 (cve.mitre.org)
mod_rewrite: Fix an off-by-one security problem in the ldap scheme
handling. For some RewriteRules this could lead to a pointer being
written out of bounds. Reported by Mark Dowd of McAfee.
[Mark Cox]
Changes with Apache 1.3.36
*) Reverted SVN rev #396294 due to unwanted regression.
The new feature introduced in 1.3.35 (Allow usage of the
"Include" configuration directive within previously "Include"d
files) has been removed in the meantime.
(http://svn.apache.org/viewcvs?rev=396294&view=rev)
Changes with Apache 1.3.35
*) SECURITY: CVE-2005-3352 (cve.mitre.org)
mod_imap: Escape untrusted referer header before outputting in HTML
to avoid potential cross-site scripting. Change also made to
ap_escape_html so we escape quotes. Reported by JPCERT.
[Mark Cox]
*) core: Allow usage of the "Include" configuration directive within
previously "Include"d files. [Colm MacCarthaigh]
*) SECURITY: CVE-2006-3918 (cve.mitre.org)
HTML-escape the Expect error message. Only a security issue if
an attacker can influence the Expect header a victim will send to a
target site (it's known that some versions of Flash can do this)
Reported by Thiago Zaninotti <thiango nstalker.com>. [Mark Cox]
*) mod_cgi: Remove block on OPTIONS method so that scripts can
respond to OPTIONS directly rather than via server default.
[Roy Fielding] PR 15242
Changes with Apache 1.3.34
*) hsregex: fix potential core dumping on 64 bit machines, such as
AMD64. PR 31858. [Glenn Strauss < gs-apache-dev gluelogic.com>]
*) SECURITY: core: If a request contains both Transfer-Encoding and
Content-Length headers, remove the Content-Length, mitigating some
HTTP Request Splitting/Spoofing attacks. This has no impact on
mod_proxy_http, yet affects any module which supports chunked
encoding yet fails to prefer T-E: chunked over the Content-Length
purported value. [Paul Querna, Joe Orton]
*) Added TraceEnable [on|off|extended] per-server directive to alter
the behavior of the TRACE method. This addresses a flaw in proxy
conformance to RFC 2616 - previously the proxy server would accept
a TRACE request body although the RFC prohibited it. The default
remains 'TraceEnable on'.
[William Rowe]
*) mod_digest: Fix another nonce string calculation issue.
[Eric Covener]
Changes with Apache 1.3.33
*) SECURITY: CVE-2004-0940 (cve.mitre.org)
mod_include: Fix potential buffer overflow with escaped characters
in SSI tag string. [Martin Kraemer, Jim Jagielski]
Changes with Apache 1.3.32
*) mod_rewrite: Fix query string handling for proxied URLs. PR 14518.
[michael teitler <michael.teitler cetelem.fr>,
Jan Kratochvil <rcpt-dev.AT.httpd.apache.org jankratochvil.net>]
*) mod_rewrite: Fix 0 bytes write into random memory position.
PR 31036. [André Malo]
*) mod_digest: Fix nonce string calculation since 1.3.31 which
would force re-authentication for every connection if
AuthDigestRealmSeed was not configured. PR 30920. [Joe Orton]
*) Trigger an error when a LoadModule directive attempts to
load a module which is built-in. This is a common error when
switching from a DSO build to a static build.
[Jeff Trawick, Geoffrey Young]
*) Fix trivial bug in mod_log_forensic that caused the child
to seg fault when certain invalid requests were fired at it with
forensic logging is enabled. PR 29313.
[Will Slater <Will Slater orbisuk.com>]
*) Fix memory leak in the cache handling of mod_rewrite. PR 27862.
[chunyan sheng <shengperson yahoo.com>, André Malo]
*) mod_rewrite no longer confuses the RewriteMap caches if
different maps defined in different virtual hosts use the
same map name. PR 26462. [André Malo]
*) mod_setenvif: Remove "support" for Remote_User variable which
never worked at all. PR 25725. [André Malo]
*) mod_usertrack: Escape the cookie name before pasting into the
regexp. [André Malo]
*) Win32: Improve error reporting after a failed attempt to spawn a
piped log process or rewrite map process. [Jeff Trawick]
*) SECURITY: CVE-2004-0492 (cve.mitre.org)
Reject responses from a remote server if sent an invalid (negative)
Content-Length. [Mark Cox]
*) Fix a bunch of cases where the return code of the regex compiler
was not checked properly. This affects mod_usertrack and
core. PR 28218. [André Malo]
*) No longer breaks mod_dav, frontpage and others. Repair a patch
in 1.3.31 which prevented discarding the request body for requests
that will be keptalive but are not currently keptalive. PR 29237.
[Jim Jagielski, Rasmus Lerdorf]
*) COMPATIBILITY: Added new compile-time flag: UCN_OFF_HONOR_PHYSICAL_PORT.
It controls how UseCanonicalName Off determines the port value if
the client doesn't provide one in the Host header. If defined during
compilation, UseCanonicalName Off will use the physical port number to
generate the canonical name. If not defined, it tries the current Port
value followed by the default port for the current scheme.
[Jim Jagielski]
Changes with Apache 1.3.31
*) SECURITY: CVE-2003-0987 (cve.mitre.org)
Verification as to whether the nonce returned in the client response
is one we issued ourselves by means of a AuthDigestRealmSeed secret
exposed as an md5(). See mod_digest documentation for more details.
The experimental mod_auth_digest.c does not have this issue.
[Dirk-Willem van Gulik, Jeff Trawick, Jim Jagielski]
Changes with Apache 1.3.30
*) Fix memory corruption problem with ap_custom_response() function.
The core per-dir config would later point to request pool data
that would be reused for different purposes on different requests.
[Will Lowe, Jeff Trawick]
*) Reinit socket to allow mod_proxy to continue to try
connections when invalid IPs are accessed. PR 27542.
[Alexander Prohorenko <white extrasy.net>]
*) SECURITY: CVE-2004-0174 (cve.mitre.org)
Fix starvation issue on listening sockets where a short-lived
connection on a rarely-accessed listening socket will cause a
child to hold the accept mutex and block out new connections until
another connection arrives on that rarely-accessed listening socket.
Enabled for some platforms known to have the issue (accept()
blocking after select() returns readable). Define
NONBLOCK_WHEN_MULTI_LISTEN if needed for your platform and not
already defined. [Jeff Trawick, Brad Nicholes, Joe Orton]
*) SECURITY: CVE-2003-0993 (cve.mitre.org)
Fix parsing of Allow/Deny rules using IP addresses without a
netmask; issue is only known to affect big-endian 64-bit
platforms; on affected platforms such rules would never produce
matches. PR 23850. [Henning Brauer <henning openbsd.org>]
*) Fix mod_include's expression parser to recognize strings correctly
even if they start with an escaped token. [André Malo]
*) The whole codebase was relicensed and is now available under
the Apache License, Version 2.0 (http://www.apache.org/licenses).
[Apache Software Foundation]
*) Add mod_whatkilledus and mod_backtrace (experimental) for
reporting diagnostic information after a child process crash.
See source code for documentation.
[Jeff Trawick, with help from mod_log_forensic]
*) mod_usertrack no longer inspects the Cookie2 header for
the cookie name. PR 11475. [Chris Darrochi <chrisd pearsoncmg.com>]
*) mod_usertrack no longer overwrites other cookies.
PR 26002. [Scott Moore <apache nopdesign.com>]
*) Add fatal exception hook for running diagnostic code after a
crash. [Jeff Trawick]
*) Make REMOTE_PORT variable available in mod_rewrite.
PR 25772. [André Malo]
*) Forensic logging shouldn't log internal redirects.
[Ivan Ristic <ivanr webkreator.com>]
*) Some syntax errors in mod_mime_magic's magic file can result
in a 500 error, which previously was unlogged. Now we log the
error. PR 8329. [Jeff Trawick]
*) Linux 2.4+: If Apache is started as root and you code
CoreDumpDirectory, coredumps are enabled via the prctl() syscall.
Backport of a 2.x feature by Greg Ames. [Jeff Trawick]
*) Fix bug causing core dump when using CookieTracking without
specifying a CookieName directly. Bugz# 24483.
[Manni Wood <manniwood planet-save.com>, Jim Jagielski (backport)]
*) Fix RewriteBase directive to not add double slashes. [André Malo]
*) mod_rewrite: In external rewrite maps lookup keys containing
a newline now cause a lookup failure. PR 14453.
[Cedric Gavage <cedric.gavage unixtech.be>, André Malo]
*) Forensic logging module added (mod_log_forensic).
[Ben Laurie]
*) SECURITY: CVE-2003-0020 (cve.mitre.org)
Escape arbitrary data before writing into the errorlog. Unescaped
errorlogs are still possible using the compile time switch
"-DAP_UNSAFE_ERROR_LOG_UNESCAPED". [Geoffrey Young, André Malo]
*) '%X' is now accepted as an alias for '%c' in the
LogFormat directive. This allows you to configure logging
to still log the connection status even with mod_ssl
(which changes what '%c' means). [Jim Jagielski]
*) UseCanonicalName off was ignoring the client provided
port information. [Jim Jagielski]
Changes with Apache 1.3.29
*) SECURITY: CVE-2003-0542 (cve.mitre.org)
Fix buffer overflows in mod_alias and mod_rewrite which occurred if
one configured a regular expression with more than 9 captures.
[André Malo]
*) Within ap_bclose(), ap_pclosesocket() is now called consistently
for sockets and ap_pclosef() for files. Also, closesocket()
is used consistenly to close socket fd's. The previous
confusion between socket and file fd's would cause problems
with some applications now that we proactively close fd's to
prevent leakage. PR 22805
[Radu Greab <rgreab fx.ro>, Jim Jagielski]
*) If a request fails and the client will be redirected to another URL
due to ErrorDocument, see if we need to drop the connection after
sending the 302 response. This fixes a problem where Apache treated
the body of the failed request as the next request on a keepalive
connection. The subsequent 501 error sent to the browser prevented
some browsers from fetching the error document. [Jeff Trawick]
*) Fixed mod_usertrack to not get false positive matches on the
user-tracking cookie's name. PR 16661.
[Manni Wood <manniwood planet-save.com>]
*) Enabled RFC1413 ident functionality for both Win32 and
NetWare platforms. This also included an alternate thread safe
implementation of the socket timout functionality when querying
the identd daemon.
[Brad Nicholes, William Rowe]
*) Prevent creation of subprocess Zombies when using CGI wrappers
such as suExec and cgiwrap. PR 21737. [Numerous]
*) ab: Overlong credentials given via command line no longer clobber
the buffer. [André Malo]
*) Fix ProxyPass for ftp requests - the original code was segfaulting since
many of the values were not being filled out in the request_rec.
[Tollef Fog Heen <tfheen debian.org>, Thom May]
Changes with Apache 1.3.28
*) SECURITY: CVE-2003-0460 (cve.mitre.org)
Fix the rotatelogs support program on Win32 and OS/2 to ignore
special control characters received over the pipe. Previously
such characters could cause rotatelogs to quit logging and exit.
[André Malo]
*) Prevent the server from crashing when entering infinite loops. The
new LimitInternalRecursion directive configures limits of subsequent
internal redirects and nested subrequests, after which the request
will be aborted. PR 19753 (and probably others).
[William Rowe, Jeff Trawick, Jim Jagielski, André Malo]
*) Fix NULL-pointer issue in ab when parsing an incomplete or non-HTTP
response. PR 21085. [Glenn Nielsen <glenn apache.org>, André Malo]
*) Removed BIND_NOSTART from HP/UX shl_load() logic for loadable
Apache modules, so that statics are initialized when the module
is loaded (especially critical for c++ modules on HPUX.)
[William Rowe, Noah Arliss <narliss netegrity.com>]
*) Win32 build system changes; always recompile buildmark.c (used for
Apache -v 'server built' messages) even when Apache is built from
within the IDE; build test_char.h and uri_delims.h from within the
ApacheCore.dsp project. PR 12706. [William Rowe]
*) Introduce Win32 .pdb diagnostic symbols into the Apache 1.3 build
(as created in Apache 2.0.45 and later.) Makes debugging and
analysis of crash dumps and Dr. Watson logs trivial. Requires the
Win32 binary builder to set aside the exact .pdb files that match
the released binaries (.exe/.so files) for reference by users and
developers. [William Rowe]
*) Make sure the accept mutex is released before calling child exit
hooks and cleanups. Otherwise, modules can segfault in such code
and, with pthread mutexes, leave the server deadlocked. Even if
the module doesn't segfault, if it performs extensive processing
it can temporarily prevent the server from accepting new
connections. [Jeff Trawick]
*) Fix mod_rewrite's handling of absolute URIs. The escaping routines
now work scheme dependent and the query string will only be
appended if supported by the particular scheme. [André Malo]
*) Use appropriate language codes for Czech (cs) and Traditional Chinese
(zh-tw) in default config files. PR 9427. [André Malo]
*) Don't block synchronous signals (e.g., SIGSEGV) while waiting for
and holding a pthread accept mutex. [Jeff Trawick]
*) AIX: Change the default accept mechanism from pthread back to
fcntl. Idle child cleanup doesn't work when the child selected
for termination by the parent is waiting on a pthread mutex, and
because the AIX kernel's notion of hot process is apparently the
same as Apache's, it is common for the Apache parent to continually
select a child for termination that the kernel will leave waiting
on the mutex for extended periods of time. There are other
concerns with pthread mutexes as well, such as the ability to
deadlock the server if a child process segfaults while holding the
mutex. [Jeff Trawick]
*) Fix a pair of potential buffer overflows in htdigest
[Martin Schulze <joey infodrom.org>, Thom May]
*) A newly created child now has a start_time of 0, to prevent
mod_status from displaying a bogus value for the "time to
process most recent request" column for freshly-started children
in a previously-used scoreboard slot. [Martin Kraemer]
*) When using Redirect in directory context, append requested query
string if there's no one supplied by configuration. PR 10961.
[André Malo]
*) Fix path handling of mod_rewrite, especially on non-unix systems.
There was some confusion between local paths and URL paths.
PR 12902. [André Malo]
*) backport from 2.x series: Prevent endless loops of internal redirects
in mod_rewrite by aborting after exceeding a limit of internal redirects.
The limit defaults to 10 and can be changed using the RewriteOptions
directive. PR 17462. [André Malo]
*) Use the correct locations of srm.conf and access.conf when tailoring
the httpd.conf during the install process. PR 9446.
[Stanislav Brabec <utx penguin.cz>]
*) suexec: Be more pedantic when cleaning environment. Clean it
immediately after startup. PR 2790, 10449.
[Jeff Stewart <jws purdue.edu>, André Malo]
*) Fix apxs to insert LoadModule/AddModule directives only outside of
sections. PR 8712, 9012. [André Malo]
*) Fix suexec compile error under SUNOS4, where strerror() doesn't
exist. PR 5913, 9977.
[Jonathan W Miner <Jonathan.W.Miner lmco.com>]
*) Unix build: Add support for environment variable
EXTRA_LDFLAGS_SHLIB, which allows the user to add to the hard-coded
ld flags specified for DSOs. Compare with the existing LDFLAGS_SHLIB
environment variable, which allows the user to completely replace the
hard-coded ld flags specified for DSOs. [Jeff Trawick]
*) mod_auth_digest no longer tries to guess AuthDigestDomain, if it's
not specified. Now it assumes "/" as already documented. PR 16937.
[André Malo]
*) In configure always assume suexec-umask to be an octal value by
prepending a "0". PR 16984. [André Malo]
*) Fix typo in suexec -V output. PR 9034.
[Youichirou Koga <y-koga apache.or.jp>]
*) Fix bug where 'Satisfy Any' without an AuthType resulted in an
"Internal Server Error" response. PR 9076. [André Malo]
*) mod_rewrite: Allow "RewriteEngine Off" even if no
"Options FollowSymlinks" (or SymlinksIfOwnermatch) is set.
PR 12395. [André Malo]
*) Change the log messages for setsockopt(TCP_NODELAY) and
getsockname() failures to log the client IP address and to
change the log level to debug. [Jeff Trawick]
*) Correction to mod_negotation for Win32, OS2, Netware etc, where
case insensitive requests such as the HEADER or README search
from autoindex would fail to match HEADER.html (because the
system internally looked for the case-sensitive header.* pattern.)
PR 7300 [William Rowe]
*) Correction to mod_autoindex so that only text/* files (prefering
/html, then /plain, then some other flavor) can be recovered
from a multiview-based HEADER or README subrequest.
[William Rowe]
*) Improvements to mod_usertrack that allows for a regular (verbose)
as well as "compact" version of the tracking cookie (the new
'CookieFormat' directive), and the ability to prepend a string
to the cookie via the 'CookiePrefix' directive.
[Pål Løberg <pallo initio.no>, with cleanup by Jim Jagielski]
*) Certain 3rd party modules would bypass the Apache API and not
invoke ap_cleanup_for_exec() before creating sub-processes.
To such a child process, Apache's file descriptors (lock
fd's, log files, sockets) were accessible, allowing them
direct access to Apache log file etc. Where the OS allows,
we now add proactive close functions to prevent these file
descriptors from leaking to the child processes.
[Jim Jagielski, Martin Kraemer]
*) Prevent obscenely large values of precision in ap_vformatter
from clobbering a buffer. [Sander Striker, Jim Jagielski]
*) NetWare: implemented ap_os_default_port() to resolve the
correct default port based on the request method. This fixes
a URL reconstruction problem on a redirect.
[Pavel Novy <novy feld.cvut.cz>]
*) Added new ap_register_cleanup_ex() API function which allows
for a "magic" cleanup function to be run at register time
rather than at cleanup time. Also added the
ap_note_cleanups_for_(socket|fd|file)_ex() API functions
which allows for control over whether that magic cleanup
should be called or not. This does not change the default
behavior of the non-"ex" function (eg: ap_register_cleanup).
[Jim Jagielski, concept by Ben Laurie]
*) PORT: Take advantage of OpenBSD's arc4random() function for the
initial secret [Henning Brauer <hb-apache-dev at bsws.de>]
*) If Listen directive is not a port, but just an IP, emit an
error condition as this case is ambiguous.
[Rich Bowen, Justin Erenkrantz, Cliff Woolley]
*) Update timeout algorithm in free_proc_chain. If a subprocess
did not exit immediately, the thread would sleep for 3 seconds
before checking the subprocess exit status again. In a very
common case when the subprocess was an HTTP server CGI script,
the CGI script actually exited a fraction of a second into the 3
second sleep, which effectively limited the server to serving one
CGI request every 3 seconds across a persistent connection.
PRs 6961, 8664 [Bill Stoddard]
*) mod_setenvif: Add SERVER_ADDR special keyword to allow
envariable setting according to the server IP address
which received the request. [Ken Coar]
*) PORT: Enable SINGLE_LISTEN_UNSERIALIZED_ACCEPT for AIX 4.3.2
and above. Update AIX configure logic to allow higher AIX
release numbers without having to change Apache.
[Jeff Trawick]
Changes with Apache 1.3.27
*) SECURITY: CVE-2002-0840 (cve.mitre.org)
Prevent a cross-site scripting vulnerability in the default
error page. The issue could only be exploited if the directive
UseCanonicalName is set to Off and a server is being run at
a domain that allows wildcard DNS. [Matthew Murphy]
*) SECURITY: CVE-2002-0843 (cve.mitre.org)
Fix some possible overflows in ab.c that could be exploited by
a malicious server. Reported by David Wagner. [Jim Jagielski]
*) Included a patch submitted by Sander van Zoest (#9181) and
written by Michael Radwin whichs is essentially a work around
for the adding headers to error responses. As apache does not
go through the proper chain for non 2xx responses. This patch
adds an ErrorHeader directive; which is for non 2xx replies the
direct analog of the existing Header directive. This is usefull
during 3xx redirects or more complex 4xx auth schemes. [Dirk-
Willem van Gulik]
*) Included the patch submitted by Sander van Zoest (#12712) which
prevents just 'anything' being sucked in when doing gobbeling in
complete directories - such as editor backup files and other
cruft. This patch allows us to tailor/control this properly by
allowing simple wildcards such as *.conf. [Dirk-Willem van Gulik]
*) SECURITY: CVE-2002-0839 (cve.mitre.org)
Add the new directive 'ShmemUIDisUser'. By default, Apache
will no longer set the uid/gid of SysV shared memory scoreboard
to User/Group, and it will therefore stay the uid/gid of
the parent Apache process. This is actually the way it should
be, however, some implementations may still require this, which
can be enabled by 'ShmemUIDisUser On'. Reported by iDefense.
[Jim Jagielski]
*) Fix a problem with the definition of union semun which broke
System V semaphores on systems where sizeof(int) != sizeof(long).
PR 12072 [<winterling de.ibm.com>]
*) The protocol version (eg: HTTP/1.1) in the request line parsing
is now case insensitive. This closes a few PRs and implies that
ProtocolReqCheck will trigger on *true* invalid protocols.
[Jim Jagielski]
*) Relaxed mod_digest its parsing in order to make it work
with iCal's "WebDAVFS/1.2 (01208000) Darwin/6.0 (Power Macintosh)"
User-Agent. Apache (incorrectly) insisted on a quoted URI's
in the uri field of the Authorization client header. Not
yet done for EBCDIC plaforms.
[Dirk-Willem van Gulik]
*) Back out an older patch for PR 9932, which had some incorrect
behavior. Instead, use a backport of the APR fix. This has
the nice effect that ap_snprintf() can now distinguish between
an output which was truncated, and an output which exactly
filled the buffer. [Jim Jagielski]
*) The cache in mod_proxy was incorrectly updating the Content-Length
value (to 0) from 304 responses when doing validation. Bugz#10128
[Paul Terry <paul.terry gmx.net>, <ast domdv.de>, Jim Jagielski]
*) Added support for Berkeley-DB/4.x to mod_auth_db.
[Martin Kraemer]
*) PR 10993: add image/x-icon to default httpd.conf files
[Ian Holsman, Peter Bieringer <pb bieringer.de>
*) Fix a problem in proxy where headers from other modules were
added to the response headers when this was already done in the
core already. This resulted in header (and therefore cookie)
duplication. [Martijn Schoemaker <martijn osp.nl>]
*) Fix FileETags none operation. PR 12202.
[Justin Erenkrantz, Andrew Ho <andrew tellme.com>]
*) Win32: Fix one byte buffer overflow in ap_get_win32_interpreter
when a CGI script's #! line does not contain a \r or \n (i.e.
a line feed character) in the first 1023 bytes. The overflow
is always a '\0' (string termination) character.
*) Add new "suppress-error-charset" environment variable to
allow a BrowserMatch workaround for clients that incorrectly
use the charset of a redirect as the charset of the target.
[Ken Coar]
*) Support Caldera OpenUNIX 8. [Larry Rosenman <ler lerctr.org>]
*) Use SysV semaphores by default on OpenBSD. [Henning Brauer
<hb-apache-dev bsws.de>]
*) httpd -V will now also print out the compile time defined
HARD_SERVER_LIMIT value. [Dirk-Willem van Gulik].
*) In 1.3.26, a null or all blank Content-Length field would be
triggered as an error; previous versions would silently ignore
this and assume 0. As a special case, we now allow this and
behave as we previously did. HOWEVER, previous versions would
also silently accept bogus C-L values; We do NOT do that. That
*is* an invalid value and we treat it as such.
[Jim Jagielski]
*) Add ProtocolReqCheck directive, which determines if Apache will
check for a valid protocol string in the request (eg: HTTP/1.1)
and return HTTP_BAD_REQUEST if not valid. Versions of Apache
prior to 1.3.26 would silently ignore bad protocol strings, but
1.3.26 included a more strict check. This makes it runtime
configurable. The default is On. This also removes the requirement
on an ANSI sscanf() implementation. [Jim Jagielski]
*) NetWare: implemented file locking in mod_rewrite for the NetWare
CLib platform. This fixes a bug that prevented rewrite logging
from working. [Brad Nicholes]
Changes with Apache 1.3.26
*) Potential NULL referencing fixed in the CGI module. It had
been there for 5 years. [Justin Erenkrantz]
*) Ensure that we set the result value in ap_strtol before
we return it. [Justin Erenkrantz, Jim Jagielski]
Changes with Apache 1.3.25
*) SECURITY: CVE-2002-0392 (cve.mitre.org) [CERT VU#944335]
Code changes required to address and close chunked
encoding security issues. To support this, we utilize the ANSI
functionality of strtol, and provide ap_strtol for completeness.
[Aaron Bannert, Justin Erenkrantz, Jim Jagielski, Brian Pane,
William Rowe, Cliff Woolley]
*) PORT: With OpenBSD 3.1 and up, allow modules to work on their
ELF-based architectures. [Brad <brad openbsd.org>]
*) Add X-Forwarded-Host and X-Forwarded-Server to X-Forwarded-For
to the proxy. [Thomas Eibner <thomas stderr.net>]
*) Fix a problem in mod_proxy: it would not set the number of bytes
transferred, so other modules could not access the value from
the request_rec->bytes_sent field.
[Anthony Howe <achowe at snert.com>] PR#6841
*) Fix a problem in mod_rewrite which would lead to 400 Bad Request
responses for rewriting rules which resulted in a local path.
Note: This will also reject invalid requests like
"HEAD /roaming/martin/IMAP localhost HTTP/1.0" as issued by
Netscape-4.x Roaming Profiles (on a DAV-enabled server)
[Martin Kraemer]
*) SECURITY: CVE-2003-0083 (cve.mitre.org)
Disallow anything but whitespace on the request line after the
HTTP/x.y protocol string. That prevents arbitrary user input
from ending up in the access_log and error_log. Also, special
characters (especially control characters) are escaped in the
log file now, to make a clear distinction between client-supplied
strings (with special characters) and server-side strings.
[Martin Kraemer]
*) Get rid of DEFAULT_XFERLOG as it is not used anywhere. It was
preserved by the build system, printed with "httpd -V", but
apart from that completely ignored: the default transfer log
is to not produce any transfer log.
[Martin Kraemer]
*) Fixed sending of binary files under Cygwin. PR 9185.
[Cliff Woolley]
*) Added Cygwin directory layout to config.layout file.
[Stipe Tolj, <tolj wapme-systems.de>]
*) Added a '-F' flag; which causes the mother/supervisor process to
no longer fork down and detach. But instead stays attached to
the tty - thus making live for automatic restart and exit checking
code easier. [ Contributed by Michael Handler <handler grendel.net>,
Jos Backus <jos catnook.com> [ Dirk-Willem van Gulik ]].
*) Make apxs.pl more flexible (file extensions like .so or .dll are
no longer hardcoded). [Stipe Tolj <tolj wapme-systems.de>]
*) Add an intelligent error message should no proxy submodules be
valid to handle a request. PR 8407 [Graham Leggett]
*) Allow child processes sufficient time for cleanups but making
ap_select in reclaim_child_processes more "resistant" to
signal interupts. Bugz# 8176
[David Winterbourne <davidw financenter.com>, Jim Jagielski]
*) Recognize platform specific root directories (other than
leading slash) in mod_rewrite for filename rewrite rules.
Bugz# 7492 [William Rowe]
*) For supported versions of Darwin, place dynamically loaded
Apache extensions' public symbols into the global symbol
table. This allows dynamically loaded PHP extensions.
[Marko Karppinen <markonen php.net>]
*) Correct proxy to be able to handle the unexpected 100-continue
reponses sent during PUT or POST requests. [Graham Leggett]
*) Correct a timeout problem within proxy which would force long
or slow POST requests to close after 300 seconds.
[Martin Lichtin <martin lichtin.net>, Brian Bothwell
<brian.bothwell wisdomtools.com>]
*) Add support for dechunking chunked responses in proxy.
[Graham Leggett]
*) Made AB's use of the Host: header rfc2616 compliant
by Taisuke Yamada <tai iij.ad.jp> [Dirl-Willem van Gulik].
*) Update the Red Hat Layout to match Red Hat Linux version 7.
PR BZ-7422 [Joe Orton]
*) Add some popular types to the mime magic file. PR 7730.
[Linus Walleij <triad df.lth.se>, Justin Erenkrantz]
*) Tighten up the overridden-Server-header bugfix in the proxy, by
only overriding if the request is a proxy request. It has been
pointed out that the previous fix allows CGIs and modules to
override the Server header, which is change to previous behavior.
[Graham Leggett, Joshua Slive]
*) Another fix for the multiple-cookie header bug in proxy. With some
luck this bug is actually now dead. [Graham Leggett]
Changes with Apache 1.3.24
*) Fixed a segfault in mod_include when #if, #elif, #else, or #endif
directives were improperly terminated. [Cliff Woolley]
*) Win32 SECURITY: CVE-2002-0061 (cve.mitre.org)
Introduce proper escaping of command.com and cmd.exe for Win32.
These patches close vulnerability CVE-2002-0061, identified and
reported by Ory Segal <ory.segal sanctuminc>, by which any CGI
invocation of .bat or .cmd files could compromise the system
when the .bat or .cmd was parsed the query args as an argument
to either cmd.exe /c or command.com /c. [William Rowe]
*) Add % and \r [C/R] to the dangerous Win32 shell character list.
Retain the Unix sh escapes list for compatibility.
[William Rowe]
*) Pass the command line to the cmd.exe /c interpreter double quoted.
This fixes a bug that CGI args ending in a double-quote would
cause invocation to fail. Also, treat command.com as a 16-bit
executable. [William Rowe]
*) Win32; Never invoke cmd or bat scripts based on the registry, even
for 'ScriptInterpreterSource Registry' enabled. [William Rowe]
*) Provide Win32 users a log of the cgi command invoked, to assist
in debugging scripts at LogLevel info. Also provide env vars
at LogLevel debug for additional help to admins troubleshooting
the ever mysterious "Premature end of script headers" error.
[Aaron Bannert]
*) Added the 'CGICommandArgs off' directive, to allow admins
to disable the query argument passing mechanism in Apache,
if future CGI argument vulnerabilities should be discovered.
This defaults to 'on', meaning isindex-style query arguments
are enabled. [Aaron Bannert]
*) When a proxied site was being served, Apache was replacing
the original site Server header with it's own, which is not
allowed by RFC2616. Fixed. [Graham Leggett]
*) Fixed the previous multiple-cookie fix in the proxy. Cookies
are broken in that they contain dates which in turn contain
commas - so merging and then unmerging them breaks Set-Cookie
headers. Sigh. [Graham Leggett]
*) Add ap_uuencode to the httpd.exp exports file used by
the AIX linker. [Bill Stoddard]
*) Win32: Ignore AcceptMutex directive if it is present
[Bill Stoddard]
*) mod_rewrite: restored rnd behavior that was broken in 1.3.23.
PR 10090, 10185 [Jeroen Boomgaardt <jeroen swissclue.com>]
*) NetWare: Added the command line directive -e that forces all
fatal configuration error messages to the logger screen rather
than the Apache screen before Apache is unloaded.
[Brad Nicholes <bnicholes novell.com>]
*) Add the ProxyIOBufferSize option. Previously the size of the
buffer used while reading from the remote server in proxy was
taken from ProxyReceiveBufferSize. [Graham Leggett]
*) Fix a NULL variable check in proxy where we were checking the
wrong variable. [Geff Hanoian <geff pier64.com>]
*) Fix typo in default config files related to Swedish language
documents. PR: 9906, 10040 [Tomas Ögren <stric ing.umu.se>,
Dennis Lundberg <dennis.lundberg mdh.se>]
*) apxs didn't get rebuilt when options were changed. This must have
caused much puzzlement in the past. Fixed.
[Ben Laurie]
*) No idea why an HTTP/1.1 proxy would send an HTTP/1.0 request
to a remote server by default. Fixed.
[Graham Leggett, Gabriel Russell <g.russell ieee.org>]
*) NetWare: Added the module mod_log_nw to handle log rotation.
This module adds LogRotateDaily and LogRotateInterval to allow
all of the custom logs to be either rotated on a daily basis or
on a specific interval. Based on a patch by Bertrand Demiddelaer.
[Brad Nicholes <bnicholes novell.com>]
*) Fix typo in rotatelogs.8. [Will Lowe <harpo thebackrow.net>]
*) Clean up warnings in mod_proxy [Chuck Murcko <chuck topsail.org>]
*) TPF: Use the correct subpool when opening the error log.
This prevents a possible SIGPIPE in standalone_main.
[David McCreedy <McCreedy us.ibm.com>]
*) When proxy enabled a slow frontend client to read from an
expensive backend server, it would wait until it had delivered
the response to the slow frontend client completely before
closing the backend connection. The backend connection is now
closed as soon as the last byte is read from it, freeing up
resources that would have been tied up unnecessarily.
[Graham Leggett, Igor Sysoev <is rambler-co.ru>]
*) The proxy code read chunks from the backend server in a
hardcoded amount of 8k. The existing ProxyReceiveBufferSize
parameter has been overloaded to specify the size of this buffer.
[Graham Leggett, Igor Sysoev <is rambler-co.ru>]
*) [Security] Prevent invalid client hostnames from appearing in
the log file. If a double-reverse lookup was performed (e.g.,
for an "Allow from .my.domain" directive) but failed, then
a spoofed dns-reverse-address could appear in the logs. Now
the numeric address is logged instead. Note that
reverse-address-spoofing did NOT actually allow access
to any protected resource! [Martin Kraemer]
*) Some browsers ignore cookies that have been merged into a
single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
are now unmerged in the http proxy before being sent to the
client. [Graham Leggett]
*) Fix a problem with proxy where each entry of a duplicated
header such as Set-Cookie would overwrite and obliterate the
previous value of the header, resulting in multiple header
values (like cookies) going missing.
[Graham Leggett, Joshua Slive]
*) Fix a problem with proxy where X-Cache headers were
overwriting and then obliterating upstream X-Cache headers
from other proxies.
[Graham Leggett, Jacob Rief <jacob.rief tiscover.com>]
*) Win32: Work around a bug in Windows XP that caused data
corruption on writes to the network. The WinXP bug
is tickled by the combined use of WSADuplicateSocket
and blocking send() calls.
[Bill Stoddard, Bill Rowe, Allan Edwards, Szabolcs Szakacsits]
*) Add 'IgnoreCase' keyword to the IndexOptions directive;
if active, upper- and lower-case letters are insignificant
in ordering. In other words, all A* and a* files will be
listed together, rather than the a* ones after all the [A-Z]*
ones. [Tullio Andreatta <tullio logicom.it>]
*) NetWare: Implemented the real ap_os_case_canonical_filename()
function that retrieves the accurately cased path and file
name from the file system. [Brad Nicholes <bnicholes novell.com>]
*) Fix the longstanding bug that errors (returned by src/Configure)
would not be noticed by the top level configure script.
That was bad for automated configurations. [Martin Kraemer]
*) Link with -lpthread on Solaris since we reference pthread
functions for the accept mutex. Previously, the link step
would succeed but we would link to bogus versions of the
pthread functions in libc, apparently breaking accept mutex
serialization when "AcceptMutex pthread" was used and
apparently breaking some third-party modules whether
or not "AcceptMutex pthread" was used. [Jeff Trawick]
*) The Location: response header field, used for external
redirect, *must* be an absoluteURI. The Redirect directive
tested for that, but RedirectMatch didn't -- it would allow
almost anything through. Now it will try to turn an abs_path
into an absoluteURI, but it will correctly varf like Redirect
if the final redirection target isn't an absoluteURI. [Ken Coar]
*) apxs: fix bug that prevented -S option from containing quotes.
[Ben Laurie]
*) ftp proxy: various cosmetic and functional improvements
- Allow for /%2f hack (to access the root directory / )
- properly escape generated links in dir listing
- do directory listings in ASCII, to avoid problems with EBCDIC
servers
- close data & control channels to server properly
[Martin Kraemer]
*) NetWare: Added mod_auth_dbm to the project file.
[Brad Nicholes <bnicholes novell.com>]
Changes with Apache 1.3.23
*) Changed the symbol mapping of the following from API_EXPORT
to API_EXPORT_NONSTD:
ap_snprintf(), ap_table_do(), ap_bvputs(), ap_log_error(),
ap_log_rerror(), ap_log_printf(), ap_rprintf()
[William Rowe]
*) Fixed a number of mismatched int sizes and signedness problems.
Still remains, MSVC's 'interesting' declaration of FD_SET still emits
(impotent) warnings. [William Rowe]
*) mod_proxy changes:
*) Bug fix for ap_proxy_cache_conditional(), unititialized wetag
[Zvi Har'El <rl math.technion.ac.il>]
*) Add persistent connection handling
The patch changes mod_proxy to write the reply-headers using
ap_send_http_header() instead of directly using ap_bvputs(). This not
only simplifies mod_proxy, in my opinion at least, but enables it to
make use of the features of Apache's normal header and persistent
connection machinery.
[Christian von Roques <roques mti.ag>]
*) Graham Leggett's original 1.3.12 patch, updated for 1.3.19+
Original comments:
HTTP/1.1 support for mod_proxy:
- support for Cache-Control
- conditional support If-Match, If-None-Match,
If-Unmodified-Since, Etag
- support for content negotiation using Vary
- storing of request headers (for Vary support) in cache file
- storing of updated response headers (with 304 Not Modified) in
cache file
- support for 64 bit dates and content-lengths in cache file
Fixes:
- ProxyPassReverse applied to Content-Location
- entity headers no longer stripped from response after cache
revalidation
- annotation of mod_proxy cache code
[Graham Leggett <minfrin sharp.fm>]
changes to preserve binary compatibility with httpd core, clean up
[Chuck Murcko <chuck topsail.org>]
*) HPUX 11.*: Do not kill the child process when accept()
returns ENOBUFS on HPUX 11.*.
[<madhusudan_mathihalli hp.com>]
*) PORT: Numerous additions to Cygwin, including: defaulting
to Posix thread accept mutex, excluding the call to
pthread_mutexattr_setpshared(), better proxy and DBM support, and
allowing the use of native Win32 socket ops instead of
Cygwin's Posix wrapper (for better performance). The last
item required the addition of a new Configure Rule: CYGWIN_WINSOCK.
[Stipe Tolj <tolj wapme-systems.de>]
*) Use "httpready" accept filter rather than "dataready" on
FreeBSD after 4.1.1-RELEASE where it works correctly.
[Tony Finch]
*) Fix incorrect "Content-Length" header in the 416 "range not
satisfiable" response. [Joe Orton <joe manyfish.co.uk>]
*) Add FileETag directive to control fields used when constructing
an ETag for a file-based resource. Historically the inode,
size, and mtimehave been used, but the inode factor broke
caching for systems with content fan-out across multiple
back-end servers. Now the fields used in the construction
can be controlled by configuration directives. Minor MMN
bumped; MMN went from 19990320.10 to 19990320.11.
[Ken Coar, from a patch by Phil Dietz]
*) NetWare: Fixed the access forbidden problem when requesting an
empty directory rather than showing the empty listing.
[Charles Goldman, Guenter Knauf <gk gknw.de>]
*) Cause Win32 to capture all child-worker process errors in
Apache to the main server error log, until the child can
open it's own error logs. [William Rowe]
*) Revert mod_negotation's handling of path_info and query_args
to the 1.3.20 behavior. PR: 8628, 8582, 8538 [William Rowe]
*) Modify buff.h and buff.c to enable modules to intercept the
output byte stream for dynamic page caching. A pointer to a
'filter callback' function is added to the end of buff.h.
This function, if registered by a module, is called
at the top of buff_write() and writev_it_all().
[Kevin Mallory <kmallory spidercache.com>]
*) When the default of 'Group #-1' was changed to 'Group "#-1"',
the Makefile wasn't updated to recognise the quotation marks.
[Owen Boyle <obo bourse.ch>]
*) Win32: Do not allow threads to continue handling keepalive
requests after a shutdown or restart has ben signaled.
[Bill Stoddard]
*) Win32: Accept OPTIONS * requests. [Keith Wannamaker]
*) Unixware 7.0 and later did not have a default locking
mechanism defined. This bug was introduced in apache 1.3.4.
[Dean Gaudet]
*) Prevent an Apache module from being loaded or added twice due
to duplicate LoadModule or AddModule directives (or a missing
ClearModuleList directive).
[William Rowe, Brian Pane <bpane pacbell.net>]
*) Add checkgid app to do run-time validation of Group directive
values which might cause the server to fall over, but which
are syntactically correct. [Ken Coar]
*) NetWare: Added mod_unique_id to the project file.
[Brad Nicholes <bnicholes novell.com>]
*) NetWare: Fixed a link problem with mod_vhost_alias so that it
exports the correct MODULE structure. PR 8598
[Brad Nicholes <bnicholes novell.com>]
*) Unix: The generated install script for binary distributions,
install-bindist.sh, now makes DSO files executable, like
make install. This allows a binary distribution to work on
HP-UX without any manual intervention. PR 7428
[Jeff Trawick]
*) Win32: The Apache Win32 developers generally recommend that
MaxRequestsPerChild be set to 0 to prevent the child process
from ever recycling. However, for those that do require a
non-zero setting, this patch fixes a serious bug that can cause
an apparent 'server-hang' condition where the server stops
responding to requests for a period of time. Prior to this
fix, when the child process handled MaxRequestsPerChild
connnections, the child process would stop accepting new
connections and begin allowing inactive threads to exit. The
problem was that a new process would not be created to begin
handling requests until the old process fully exited. The old
process can take an indeterminate amount of time to exit because
it may be sending large responses to clients connected over slow
links, or it may have threads blocked in read awaiting requests
(eg, one attack mode of the Nimda worm is to establish a
connection to the server but not send an HTTP request. This
connection will be timed out according to the setting of the
Timeout directive, 300 seconds). This fix allows the new process
to be immediately started and begin accepting requests when the
old child process reaches MaxRequestsPerChild.
[Bill Stoddard]
*) Win32: Emit error message when the server bumps up against the
ThreadsPerChild configuration limit. This will be useful for
admins to detect when their server is running out of threads
to handle requests. [Bill Stoddard]
*) Test all directories listed with the UserDir directive for validity.
Also resolves the Win32/Netware bug of unparsable quoted paths.
PR 8238 [William Rowe]
Changes with Apache 1.3.22
*) Recognize AIX 5.1. [Jeff Trawick]
*) PORT: Support AtheOS (see www.atheos.cx)
[Rodrigo Parra Novo <rodarvus terra.com.br>]
*) The manual directory is still configurable (as enabled by
the 1.3.21 change), but its default setting was reverted to
the pre-1.3.21 default as a subdirectory of the DocumentRoot.
You can adapt your path in config.layout or with the
"configure --manualdir=" switch. [Martin Kraemer]
*) Additional correction for the mutex changes on the TPF platform.
[David McCreedy <McCreedy us.ibm.com>]
*) mod_proxy - remove Explain*; replace with ap_log_*
[Chuck Murcko <chuck topsail.org>]
Changes with Apache 1.3.21
*) Enable mod_mime_magic (experimental) for Win32. [William Rowe]
*) Use an installed Expat library rather than the bundled Expat. This
fixes a problem where multiple copies of Expat could be loaded
into the process space, thus conflicting and causing strange
segfaults. Most notably with mod_perl and XML::Parsers::Expat.
[Greg Stein]
*) Handle user modification of WinNT/2K service display names. Prior
versions of Apache only accepted identical internal and display names
(where internal service names were space-stripped.) [William Rowe]
*) Introduce Win32 -W option for -k install/config to set up service
dependencies on the workstation, snmp and other services that given
modules or configurations might depend upon. [William Rowe]
*) Update the mime.types file to map video/vnd.mpegurl to mxu
and add commonly used audio/x-mpegurl for m3u extensions.
[Heiko Recktenwald <uzs106 uni-bonn.de>, Lars Eilebrecht]
*) Modified mod_mime and mod_negotiation to prevent mod_negotiation
from serving any multiview variant containing one or more
'unknown' filename extensions. In PR #8130, mod_negotiation was
incorrectly serving index.html.zh.Big5 when better variants were
available. The httpd.conf file on the failing server did not have
an AddLanguage directive for .zh, which caused mod_mime to loose
the file_type information it gleened from parsing the .html
extension. The absence of any language preferences, either in
the browser or configured on the server, caused mod_negotiation
to consider all the variants equivalent. When that occurs,
mod_negotiation picks the 'smallest' variant available, which
just happened to be index.html.zh.Big5.
[Bill Stoddard, Bill Rowe] PR #8130
*) SECURITY: CVE-2001-0731 (cve.mitre.org)
Close autoindex /?M=D directory listing hole reported
in bugtraq id 3009. In some configurations where multiviews and
indexes are enabled for a directory, requesting URI /?M=D could
result in a directory listing being returned to the client rather
than the negotiated index.html variant that was configured and
expected. The work around for this problem (for pre 1.3.21
releases) is to disable Indexes or Multiviews in the affected
directories. [Bill Stoddard, Bill Rowe]
*) Enabled Win32/OS2/Netware file paths (not / rooted, but c:/ rooted)

*) Win32 SECURITY: CVE-2001-0729 (cve.mitre.org)
The default installation could lead to mod_negotiation

the index.html.* files, if a very long path was created artificially
by using many slashes. Now a 403 FORBIDDEN is returned. This
problem was similar to and in the same area as the problem
reported and fixed by Martin Kraemer in 1.3.18, only the scope
is much narrower and is specific to Windows. [Bill Stoddard]

[William Rowe]
*) Enhancement of mod_auth to handle 'Require file-owner' and
'Require file-group'. This allows access IFF the authenticated
username (from the appropriate AuthUserFile database) matches
the username of the UID that owns the document (and equivalent
checking for file GID and user's membership in AuthGroupFile).
See the mod_auth documentation for examples. (Not supported
on Windows.) [Ken Coar]
*) Addition of the AcceptMutex runtime directive. The accept mutex
method is now runtime controllable. The suite of available methods
per platform is defined at compile time (with HAVE_FOO_SERIALIZED_ACCEPT
noting that the method is available and works, and
USE_FOO_SERIALIZED_ACCEPT noting that it should be the default
method in absense of any AcceptMutex line, or via AcceptMutex default)
and selectable at runtime. The full (current) suite is uslock,
pthread, sysvsem, fcntl, flock, os2sem, tpfcore and none, but
not all platforms accept all methods. [Jim Jagielski]
*) Parallel to a change in Apache-2.0, the manual directory was
moved out of the DocumentRoot tree to simplify the separation
of private content&configuration from server's on-line
documentation. An "Alias /manual/ ..." projects the manual/
directory (which resides now side-by-side with the icons/
directory) into the logical DocumentRoot. Note that a request
to http://server/manual (without the trailing slash) will now
behave different than before (it used to redirect to
http://server/manual/ but no longer does).
[Martin Kraemer]
*) Fixed ap_os_canonical_filename() so that it wouldn't try to
canonicalize an invalid file name. Also fixed
ap_os_is_path_absolute() so that it wouldn't recognize names

*) SECURITY: CVE-2001-0730 (cve.mitre.org)
Make support/split-logfile use the default log file if

*) Added a directive: "AcceptFilter <on|off>". To control BSD
acccept filters when at compile time SO_ACCEPT_FILTER is
detected. The default is still 'on' except when, at compile
time, AP_ACCEPT_FILTER_OFF is defined.
Also downgraded the fatal exit to a warning when the
associated setsocketopt(2) fails for any reason but
for ENOPROTOOPT. The latter - which implies that the
kernel does not support the filters - now rates only an
info level message. All in all this should make it easier
to move httpd binaries and config files across BSD machines
with varying acceptfilter support.

Apache could be improved to use NO_SEM_UNDO flag (see test/time-sem.c)
which is currently implemented only in the time-sem program, but not in
apache. Until then, revert to using fcntl() locks.
[Martin Kraemer]
*) Changes to 'ab': fixed int overruns, added statistics, output in
csv/gnuplot format, rudimentary SSL support and various other tweaks
to make results more true to what is measured. The upshot of this it
turns out that 'ab' has often underreported the true performance of
apache. Often by a order of magnitude :-) See talk/paper of Sander
Temme at April ApacheCon 2001 for details.
[Dirk-Willem van Gulik]
Changes with Apache 1.3.20
*) Autodetect if platforms have isnan() and/or isinf() for use in
ap_snprintf.c. [Jim Jagielski]
*) SECURITY DoS: CVE-2001-1342 (cve.mitre.org)
Correct a vulnerability in the Win32 and OS2 ports, by which a
client submitting a carefully constructed URI could cause a GP
(segment) fault in the child process, which would have to be
cleared by the operator to resume operation. This vulnerability
introduced no identified means of compromising the server's data.
Reported by Auriemma Luigi <kaino3 genie.it>.
[William Rowe, Brian Havard]
*) Resolve the Win32 SSI exec cmd bug, where cmd was not executed
appropriately against the shell. [William Rowe]
*) Added NOESCAPE (NS) flag to RewriteRule and enabled use of
'\' to allow escaping of special characters. Previously
there was no way to embed either '$' or '%' in the output
of a RewriteRule; now 'foo\$1' will result in a literal
'foo$1' appearing in the result rather than 'foo\<value of $1>'.
Note that [NS] disables *all* normal URI escaping, so incautious
use can give unexpected results. [Ken Coar]
*) Add support for Win32 apxs. Note that cygwin builders must use a
cygwin perl to avoid the MSWin32 handling. [William Rowe]
*) Changed the initial screen handling for NetWare so that the -s
parameter will properly destroy the Apache console screen and switch
to the system console screen. Also removed the call to clrscr() for
NetWare so that any warning messages produced during startup are visible.
[Brad Nicholes <BNICHOLES novell.com>]
*) Integrate support for the Cygwin 1.x platform (a POSIX emulation layer
for Win32 systems, see http://www.cygwin.com)
[Stipe Tolj <tolj wapme-systems.de>]
*) Hooked calls to opendir() and readdir() so that we could add '.' and
'..' to the entry list. By default NetWare does not return these
entries which caused mod_autoindex not to display the parent directory
entry. [Brad Nicholes <BNICHOLES novell.com>]
*) Solved a very serious threading problem with WinNT/2K Services. The
moment master_main told that the shutdown was complete, the parent
control thread exited Apache, leaving mod_jserv's Java process running
and alternately invoking mod_perl's cleanups from the correct thread
or the service control thread. [William Rowe]
*) Populate the Win32 HKLM\System\CurrentControlSet\Services\[apachesvc]
key with the Description value of the running server across all Win32
platforms, including NT, ME and 9x. This value is the server_version
string including loaded modules. [William Rowe]
*) Fix ndbm.h include problems with various Linux distributions and
brain-dead glibc >= 2.1, which sometimes have ndbm.h in a
non-standard db1/ subdir. PR#6929
[Victor J. Orlikowski]
*) Empty headers are allowed by RFC2068 section 4.2. The presence or
absence of an empty header can be significant. The current mod_proxy
of httpd 1.3.x removes empty headers. Change mod_proxy to preserve
empty headers. [Christian von Roques <roques mti.ag>]
*) Enhance rotatelogs so that a UTC offset can be specified, and
the logfile name can be formatted using strftime(3). [Ken Coar]
*) Fix a possible NULL pointer dereference in the detection of the
default ServerName or IP string (introduced in 1.3.18).
[Ignasi Roca, <Ignasi.Roca fujitsu-siemens.com>]
*) Make EBCDIC conversion fully configurable. Until now, apache relied
on some (incomplete) heuristics, and would fail to correctly serve
text files when they had a MIME type of application/anything, like
application/x-javascript. The new conversion directives allow
defining the conversion based on MIME type or file suffix.
[Martin Kraemer]
*) Add a -V flag to suexec, which causes it to display the
compile-time settings with which it was built. (Only
usable by root or the HTTPD_USER username.) [Ken Coar]
*) Set the Win32 service description in the Services control panel to
the server_version string from Apache and the loaded modules.
[William Rowe]
*) Added a new API for NetWare, ap_os_dso_unsym(), to allow Apache the
chance to unimport module symbols before it shuts down. This is
necessary so that Apache on NetWare can shutdown cleanly in an error
condition such as a failure while reading the httpd.conf file.
[Brad Nicholes <BNICHOLES novell.com>]
*) Introduce NUL device pipes for stdin and stdout for the parent Win32
service process. This solves bugs such as PR7198 that report
"dup2(stdin) failed" when trying to use piped logs. [William Rowe]
Changes with Apache 1.3.19
*) Rewrite ap_unparse_uri_components() to make it safer and more readable
["Jeffrey W. Baker" <jwbaker acm.org>]
*) Under certain circumstances, Apache did not supply the
right response headers when requiring authentication.
[Gertjan van Wingerde <Gertjan.van.Wingerde cmg.nl>] PR#7114
*) Clean up some end-of-loop not reached warnings [Jim Jagielski,
Aris Stathakis <aris sco.COM>]
*) Add the correct language tag for interoperation with the Taiwanese
versions of MSIE and Netscape. [Clive Lin <clive CirX.ORG>] PR#7142
*) Fixed system shutdown on Windows 2000 to assure that the modules have
an opportunity to clean up. Note there is a _very_ limited amount of
time in which to execute all cleanups [see MSKB Q146092] so all of
the modules may still not be given an opportunity to complete their
cleanups if they require more than 20 seconds total. [William Rowe]
Changes with Apache 1.3.18 [not released]
*) Workaround enabled for a core dump which appeared in broken
NameVirtualHost configurations. [Martin Kraemer]
*) Sporadic core dump in ap_default_port_for_scheme() with
internal requests fixed by [Jeffrey W. Baker <jwbaker acm.org>]
*) PORT: Allow for build under latest dev. version of NonStopUX
on Compaq. [Tom Bates <tom.bates compaq.com>]
*) mod_user on Win32 bug introduced in 1.3.17 is corrected. The parsing
is completely rewritten so all platforms share the same file/redirect
logic interpreting UserDir directives. Specifying a Win32 or Netware
relative path or a relative path on any platform using an '*' now
emits an error when httpd.conf is first parsed. [William Rowe]
*) Apache/Win32 no longer holds open the console on error, unless invoked
by a shortcut with the new -w option. [William Rowe]
*) The Win32 -t test config now holds the console open on "SYNTAX OK".
[William Rowe]
*) Apache on Win9x now ensures the service is stopped before removal.
[William Rowe]
*) SECURITY: CVE-2001-0925 (cve.mitre.org)
The default installation could lead to mod_negotiation
and mod_dir/mod_autoindex displaying a directory listing instead of
the index.html.* files, if a very long path was created artificially
by using many slashes. Now a 403 FORBIDDEN is returned.
[Martin Kraemer]
*) Trailing slashes (if they exist) are now removed from ServerRoot,
because there were known problems with them.
["William A. Rowe, Jr." <wrowe rowe-clan.net>]
*) Changed ap_os_is_filename_valid on NetWare to accept
SERVER/VOLUME:/PATH/FILE as a valid filename pattern.
[Brad Nicholes <BNICHOLES novell.com>]
*) Win32/Netware: correct relative paths and eliminate trailing slash
in the -d serverroot argument. -d Serverroot may be relative to
the path of the Apache.exe file. [William Rowe]
*) Win32; fix the ServerRoot as the path of the Apache.exe file.
Eliminates the requirement of a 'backup' registry key to locate
the server root. [William Rowe]
*) NetWare MOD_TLS fixes to disable nagles properly when making an SSL
connection, and properly detect an SSL connection based on the port
and work around the r->server->port 80 bug.
[Brad Nicholes <BNICHOLES novell.com>]
*) TPF startup/shutdown fixes. [David McCreedy <McCreedy us.ibm.com>]
*) Correct a typo in httpd.conf.
[Kunihiro Tanaka <tanaka apache.or.jp>] PR#7154
*) Get the correct IP address if ServerName isn't set and we can't
find a fully-qualified domain name at startup.
[Danek Duvall <dduvall eng.sun.com>] PR#7170
*) Fix pointer arithmetic in mod_rewrite map expansion.
[Christopher A. Bongaarts <cab tc.umn.edu>] PR#7157, 7158
*) Fixed a problem with file extensions being truncated during
the call to ap_os_canonical_filename().
[Brad Nicholes <BNICHOLES novell.com>]
Changes with Apache 1.3.17
*) Normalize the Netware path names to close a potential security
hole in comparing paths when the adminstrator specifies both
sys:foo and sys:/foo formats in the same httpd.conf file.
[Brad Nicholes]
*) Fix an unlikely segfault provided a zero length string in the
translate_userdir() call on win32/os2, and accept backslashes
in the UserDir directive on those platforms [William Rowe]
*) Fixed translate_userdir() in MOD_USERDIR.C so that it correctly
recognizes NetWare absolute paths. This fixes the problem where
MOD_USERDIR was trying to redirect to an absolute NetWare path
rather than opening the file at the specified location. This
patch fixes PR5826 & 6283. [Brad Nicholes <BNICHOLES novell.com>]
*) Fixed ap_os_is_path_absolute() in OS.H so that it can tell the
between a NetWare path (SYS:/path) and a URL (HTTP://path).
[Brad Nicholes <BNICHOLES novell.com>]
*) Fixed the sdbm.h bundled in Apache for Win32, bringing it in sync
with Perl. Because it didn't have the same geometry as Perl,
users reported the first user added with dbmmanage was not
recognized. [William Rowe]
*) Fixed ap_os_canonical_filename to append a the default volume
name if the the path is a full path and does not include the
volume name. Since NetWare's current working directory always
defaults to the SYS: volume regardless of where the executible
started, the default volume will be the volume that is specified
in ap_server_root. [Brad Nicholes <BNICHOLES novell.com>]
*) Handle port numbers in Host headers properly again after
the code was broken in 1.3.15. [Tony Finch]
Changes with Apache 1.3.16 [not released]
*) None from 1.3.15 [repository tags were the issue, no code altered]
Changes with Apache 1.3.15 [not released]
*) Fix a new problem introduced with the -k config syntax, that the
service installed with the -i flag would attempt to re-install
itself when starting the server. [William Rowe, Andrew Braund]
*) Fix the declaration of the module structure in mod_example.
[Gururaj Upadhye <gururaj enertec.com>] PR#7095
*) Fix the handling of variable expansion look-ahead in mod_rewrite,
i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
more complicated nested RewriteMap lookups. [Tony Finch] PR#7087
*) Fix the RFC number mentioned when complaining about a missing
Host: header. [Alexey Toptygin <alexeyt wam.umd.edu>] PR#7079
*) Fix Range header processing to properly parse the syntax specified
in RFC 2616, and properly handle unsatisfiable requests by returning
a 416 error. [Tony Finch, William Rowe] PR#6973
*) Remove some human-readable fluff from the machine-readable mod_status
display. [Youichirou Koga <y-koga apache.or.jp>] PR#7025
*) The new Win32 command line option, -k config, replaces the default
options for the existing, named service with the options given on
the -k config command line. Apache -n servicename -t now displays
the default options before it tests the httpd.conf. Use the syntax
apache -k config -n servicename -f conffile to upgrade an existing
1.3.x service to the new 1.3.15 default arguments. [William Rowe]
*) All Win32 services now support default command line options when
starting an Apache service. The command line options given with
the apache -k install command, including -d, -f, -D, -C and -c,
are all saved in the registry. This change superceeds the old
ConfPath entry, so existing services must be reconfigured when
upgrading to 1.3.15. [William Rowe]
*) The Win32 build is overhauled to use mod_foo.so for all dynamic
Apache modules. [William Rowe]
*) The Win32 build scripts (makefile.win, Apache.dsw) now build
all the usual targets, including the directories htdocs, include,
lib, libexec, and cgi-bin. [William Rowe]
*) WinNT/2K service can be started from the command line with any
desired args (e.g. Apache -k start -n apache-1.3 -D FOO will
start the service with the -D FOO option.) This extends what
Apache on Win9x already does, even running as a service.
[William Rowe]
*) WinNT/2K can be started from the Services control panel adding
whatever args are desired (e.g. -D ARG) in the 'Start Parameters'
box of the start service dialog. These will be passed on and
recognized by the service as it starts. [William Rowe]
*) Support -k install/-k uninstall on Win32 for compatibility with
Apache 2.0. [William Rowe]
*) mod_cgi on Win32 and Netware now does a more effective job of
capturing all stderr output from user's scripts. PR6161
[Hardy Braunsdorf <hardy.braunsdorf metechnology.com>, Will Rowe]
*) mod_status now respects ?refresh=n of 1 or greater. If the given
refresh value is not a number, ?refresh is set to 1 second.
[William Rowe, Dirk Ahlers <there darkride.net> PR5067]
*) Restore child process consoles to correct 16-bit CGI execution
on Windows. Relies on Win9xConHook.dll for Win9x. This patch
also assures the Apache window remains titled 'Apache', rather
than flickering to the cgi app titles. [William Rowe]
*) Added Win9xConHook.dll, which uses hidden console spy windows to
handle the shutdown, logoff and Close button events, and dispatch
them to Apache just as SetConsoleCtrlHandler does on Win NT/2K.
The close button on Win9x now works, and the Win9x service support
code moved into this module. [William Rowe]
*) Fix messages from the -k start/stop/restart command options on
Windows. [William Rowe]
*) Allow Win32 users to build mod_isapi, regardless of the age of
their Win32 SDK headers. Warning provided if features must be
disabled due to old headers. [William Rowe]
*) The ScriptInterpreterSource Registry source will now handle any
post-scriptname arguments (e.g. cmd script -q), substitute any
environment variables (e.g. "%windir%\sysapp.exe") and use the
short or long path name as appropriate (e.g. "doit %1" uses the
short form, no spaces, while "doit "%1"" uses the long form of
the script name, in quotes.) Also, passes all script names in
backslash delimited format (instead of slashes). [William Rowe]
*) Accomodate an out-of-space condition in the piped logs and the
rotatelogs.c code, and no longer churn log processes for this
condition. [Victor J. Orlikowski]
*) Make cgi-bin work as a regular directory when using mod_vhost_alias
with no VirtualScriptAlias directives. [Tony Finch] PR#6829
*) Move the check of the Expect request header field after the hook
for ap_post_read_request, since that is the only opportunity for
modules to handle Expect extensions.
[Justin Erenkrantz <jerenkrantz eBuilt.com>]
*) Add default CacheGcInterval of one hour [ Chuck Murcko ]
*) Each Netware thread is created in its own thread group to ensure
that any context change applies only to the thread in which the
change was made. [Brad Nicholes <BNICHOLES novell.com>]
*) Relax the syntax checking of Host: headers in order to support
iDNS. [Tony Finch] PR#6635
*) Fix Content-Length calculation when doing Range header processing.
This makes PDF byteserving work again. [Tony Finch] PR#6711
*) Link with libresolv on UnixWare 7 so that PHP works.
[Larry Rosenman <ler lerctr.org>] PR#6780
*) Linux 2.2.x and later do not need a serialised single listener,
and sysv semaphores scale better than fcntl. Updated GuessOS
to distinguish 2.0.x from 2.2.x -- 2.0.x will still use fcntl.
[Andrew Morton <andrewm uow.edu.au>, Dean Gaudet]
*) Eliminate caching problems of mod_autoindex results, so the last
modified date of the directory is returned as the Last-Modified
and ETag HTTP header tags are sent if IndexOptions TrackModified
directive/option is used. [William Rowe]
*) Corrected file path arguments from server conf directives to
their canonical form (excluding OS2 - which uses alternate
logic.) Resolves a long list of PRs reporting that Win32 paths
of the syntax x:\foo were mis-concatinated to the server root
as of release 1.3.14. [William Rowe]
*) Correct an issue with Alias and ScriptAlias directives that
file path arguments were not normalized in canonical form.
This correction makes no attempt to normalize regular expression
forms of Alias or ScriptAlias. [William Rowe]
*) Add a new LogFormat directive, %c, that will log connection
status at the end of the response as follows:
'X' - connection aborted before the response completed.
'+' - connection may be kept-alive by the server.
'-' - connection will be closed by the server.
[Bill Stoddard <stoddard apache.org>]
*) Normalize all NetWare config directive paths and filespecs to
their canonical names. [Brad Nicholes <bnicholes novell.com>]
*) Update the mime.types file to the registered media types as
of 2000-10-19. [Carsten Klapp <carsten.klapp home.net>,
Tony Finch] PR#6613
*) Restore functionality broken by the mod_rewrite security fix:
rewrite map lookup keys and default values are now expanded
so that the lookup can depend on the requested URI etc.
[Tony Finch] PR #6671
Changes with Apache 1.3.14
*) Fixes to allow compilation on NetWare [Brad Nicholes
<bnicholes novell.com>]
Changes with Apache 1.3.13 [not released]
*) NOTE: A number of Win32 symbols were exported without explicit
declaration in the ApacheCore.def file. These are now exported
with the same ordinal export values from 1.3.12, but are now
named consistent with Apache's conventions. [William Rowe]
*) Add support for a "conf directory" which operates similar to
/etc/rc.d/init. Basically, if a config file is actually a
directory, all the files in that directory will be parsed
as conf files. PR #6397 [Jim Jagielski, Lionel Clark
<bishop platypus.bc.ca>]
*) Initial support added for mod_proxy under MPE/iX.
[Mark Bixby <mark_bixby hp.com>]
*) Refined UID/GID management and permissions on MPE/iX to deal
with some limitations. [Mark Bixby <mark_bixby hp.com>]
*) Updated the MPE DSO code to be compatible with an OS patch that
fixed an earlier DSO problem, #include tweakage required for
using apxs to build modules without access to the full source
tree, and other minor MPE tweaks.
[Mark Bixby <mark_bixby hp.com>]
*) SECURITY: Tighten up the syntax checking of Host: headers to fix a
security bug in some mass virtual hosting configurations
that can allow a remote attacker to retrieve some files
on the system that should be inaccessible. [Tony Finch]
*) Add support for /, //, //servername and //server/sharename
parsing of <Directory > blocks under Win32 and OS2.
[Tim Costello, William Rowe, Brian Havard]
*) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
SHA1 and plaintext password encodings. Make feature tests a
bit more flexible. [William Rowe]
*) SECURITY: CVE-2000-0913 (cve.mitre.org)
Fix a security problem that affects some configurations of
mod_rewrite. If the result of a RewriteRule is a filename that
contains expansion specifiers, especially regexp backreferences
$0..$9 and %0..%9, then it may have been possible for an attacker
to access any file on the web server. [Tony Finch]
*) Add mod_auth_dbm (sdbm flavor) binary build for Win32.
[William Rowe]
*) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
as well as a comment arg to the add, adduser and update cmds.
update allows the user to clear or preserve pw/groups/comment.
Fixed a bug in dbmmanage that prevented the check option from
parsing a password followed by :group... text. Corrected the
seed calcualation for Win32 systems, and added -lsdbm support.
[William Rowe]
*) Radical surgery to improve mod_isapi support under Win32.
Includes a number of newer ServerSupportFunction calls, support
for ReadClient (in order to retrieve POSTs greater than 48KB),
and general bug fixes to more reliably load ISAPI .dll's and
prevent leaking handle resources. Note: There are still
discrepancies between IIS's and Apache's ServerVariables, and
async calls are still not supported. Additional warnings are
logged to facilitate debugging of unsupported ISAPI calls.
[William Rowe]
*) Update Configure script to allow building Apache on IBM's
IA64 version of AIX. [Paul Reder]
*) NameVirtualHost can now take "*" as an argument instead of
an IP address. This allows you to create a purely name-based
virtual hosting server that does not have any IP addresses in
the configuration file and which ignores the local address
of any connections. PR #5595, PR #4455 [Tony Finch]
*) Fix processing/merging of Remove* MIME directives.
PR #5597 [Sander van Zoest <sander covalent.net>]
*) Fix merging of AddDefaultCharset directive.
PR #5872 [Jun Kuriyama <kuriyama imgsrc.co.jp>]
*) Win32: Work around bug in Win32 select on network reads. Select
can indicate a socket has data to read, but the subsequent read
can return WSAEWOULDBLOCK. This problem has been observed
when running with SSL enabled Apache, specifically, browsers
sometimes cannot complete the SSL handshake when an SGC
certificate is used, receiving a network error message.
[Richard Scholz <richard.scholz subito.de>]
*) Use "accept filtering" on recent versions of FreeBSD iff the
kernel is configured to support them. This allows Apache to avoid
having to handle new connections until the request has arrived.
[Tony Finch]
*) Fix error handling in make_sock. [Tony Finch]
*) The htdocs/ tree has been moved out of the CVS source tree into
a separate area for easier development. This has NO EFFECT on
end-users or Apache installations. [Ken Coar]
*) Fix problem matching Configure guessos on HP-UX 10.
[Victor J. Orlikowski] PR#6015
*) Correct the problem where the only local host name that the IP stack
can discover are 'undotted' private names. If no fully qualified
domain name can be identified, the default ServerName will be set to
the machine's IP address string. A warning is provided if Apache has
to assume the IP dotted address string or the localhost/loopback
address as the ServerName. The default ServerName is removed from
the default Win32 httpd.conf file. [William Rowe]
*) Add new directives RemoveType and RemoveEncoding to accompany the
RemoveHandler directive added in 1.3.4. AddType, AddEncoding, and
AddHandler now all have corresponding 'undo' directives. This allows
things like marking foo.tar.gz.asc as *not* being gzipped, so it will be
correctly interpreted as an unzipped signature of a gzipped file.
[Ken Coar]
*) Win32 NT and 2000 services now capture stderr messages that occur
before Apache's logs are opened to the Application Event Log.
Console and Win9x services now hold the console open for 30 seconds
(and may be dismissed with the <ESC> key) if they exit with an error.
[William Rowe]
*) Expand Win32 protection for pathname length, to provide protection
from future potential bugs such as that which caused directory index
to be displayed rather than returning an error.

[Tony Finch]
*) Under Win32, The console input mode is fixed to ignore mouse events
and always listen for a Ctrl+C interrupt, even if the console window
defaults to another mode. [William Rowe]
*) All Win32 services will now perform a graceful restart when given
the -n servicename -k restart signal. No equivilant control exists
in the service control panel applet or through the NET command.
There is no useful acknowledgement on Windows 95/98, however.
[William Rowe]
*) Significant overhaul of the Win32 port documentation contained in
the README-WIN.TXT, as well as the htdocs/manual pages windows.html,
win_compiling.html, and the new win_service.html.
[Andrew Braund <abraund dingoblue.net.au>, William Rowe]
*) Add 'services' for Windows 95 and 98, including install/uninstall
options. The Apache server therefore can start when the OS loads,

obtrusive code, faster load times, and a smaller executable size.
libprews.c contains WSAStartup and WSACleanup WinSock calls needed for
initialization and termination of DSO modules.

*) Various fixes to mod_auth_digest:
- Reworked MD5-sess stuff. The semantics of userpw_hash() have been
changed for it to return
MD5(MD5(username ":" realm ":" password) ":" nonce ":" cnonce)
instead of just
MD5(username ":" realm ":" password)
because one of the points of MD5-sess is to allow the info to be
retrieved from login servers so that the server itself never has
the full auth info (after all, MD5(u/r/p) is equivalent to the
password for auth purposes).
- In order to allow for servers to share a realm the server-name
and port have been removed from the nonce-hash. Even so, sharing
the realm has problems - see the new comments at the beginning.
- Fixed uri-comparison when request-uri isn't identical to uri in
Authorization header (some fields were not being initialized).
- Handle non-FQDN's (i.e. simple hostnames) in uri parameter in
the Authorization header. Thanks to Joe Orton
<joe orton.demon.co.uk> for pointing out the problem.
[Ronald Tschalär]
*) Add case_preserved_filename field to the request_rec structure.
On systems with case insensitive file systems (Windows, OS/2, etc.),
r->filename is case canonicalized (folded to either lower or upper
case, depending on the specific system) to accomodate file access
checking. case_preserved_filename is the same as r->filename
except case is preserved. There is at least one instance where Apache
needs access to the case preserved filename: Java class files published
with WebDAV need to preserve filename case to make the Java compiler
happy. [Bill Stoddard]
*) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
which where donated by Lee Kuk Hyun and Lorant Czaran [dirkx].
*) Modules which load third-party DLLs (ala mod_dav)

*) Merged in a small subset of SGI's latest `10x' patchkit for Apache
1.3.11. The extracted and merged in parts are entirely cleanup and
non-performance related changes only. SGI's remaining changes are
not taken over, because they are either cluttering the Apache 1.3
sources too much (e.g. the lint(1) related changes) or cause too
much internal changes (e.g. the ap_int32 types, etc.) which are not
reasonable to do any longer for Apache 1.3 (they should be done for
Apache 2.0 instead).

Change mod_actions, mod_autoindex, mod_expires, and mod_log_config to
not consider any parameters such as charset when making decisions
based on content type. This does remove some functionality for
some users, but means that when these modules are configured to do
particular things with particular MIME types, the charset should
not be included. A better way of addressing this for users who
want to set things on a per charset basis is necessary in the future.

[Michael Ottati <michael.ottati compaq.com>, dirkx]
*) Added SHA1 password encryption support to easy migration from
Netscape servers. See support/SHA1 for more information.
Caused the separation of ap_md5.c into md5, sha1 and a general
ap_checkpass.c with just a validate_passwd routine. Added a
couple of flags to support/htpasswd. Some reuse of the to64()
function; hence renamed to ap_to64().

*) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
Change "Power Macintosh" to Power* so if uname prints "Power Book"
we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
*) Fix SIGSEGV on some systems because the Vary fix below included
a call to table_do with a variable argument list that was not
NULL terminated. Replaced with better implementation. [Roy Fielding]
Changes with Apache 1.3.7 [not released]
*) The "Vary" response header field is now sanitised right before
the header is sent back to the client. Multiple "Vary" fields
are combined, and duplicate tokens (e.g., "Vary: host, host" or
"Vary: host, negotiate, host, accept-language") are reduced to
single instances. This is a better solution than the force-no-vary
one (which is still valid for clients that can't cope with Vary
at all). [Dean Gaudet, Roy Fielding, Ken Coar] PR#3118
*) Portability changes for BeOS. [David Reid <abb37 dial.pipex.com>]
*) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
least on Linux and FreeBSD for now.
[Rasmus Lerdorf]
*) Win32: More apache -k restart work. Restarts are now honored
immediately and connections in the listen queue are -not- lost.
This is made possible by the use of the WSADuplicateSocket()
call. The listeners are opened in the parent, duplicated, then
the duplicates are passed to the child. The original listen sockets
are not closed by the parent across a restart, thus the listen queue
is preserved.
[Bill Stoddard <stoddard raleigh.ibm.com>]
*) Fix handling of case when a client has sent "Expect: 100-continue"
and we are going to respond with an error, but get stuck waiting to
discard the body in the pointless hope of preserving the connection.
[Roy Fielding, Joe Orton <jeo101 york.ac.uk>] PR#4499, PR#3806
*) Fix 'configure' to work correctly with SysV-based versions of
'tr' (consistent with Configure's use as well). [Jim Jagielski]
*) apxs: Add "-S var=val" option which allows for override of CFG_*
built-in values. Add "-e" option which works like -i but doesn't
install the DSO; useful for editing httpd.conf with apxs. Fix
editing code so that multiple invocations of apxs -a will not
create duplicate LoadModule/AddModule entries; apxs can now be
used to re- enable/disable a module. [Wilfredo Sanchez]
*) Win32: Update the server to use Winsock 2. Specifically, link with
ws2_32.lib rather than wsock32.lib. This gives us access to
WSADuplcateSocket() in addition to some other enhanced comm APIs.
Win 95 users may need to update their TCP/IP stack to pick up
Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
[Bill Stoddard <stoddard raleigh.ibm.com>]

*) Better GCC detection for DSO flags under Solaris 2 where the `cc'
command potentially _is_ GCC. [Ralf S. Engelschall]
*) Fix apxs build issues on AIX
[Rasmus Lerdorf <rasmus raleigh.ibm.com>]
*) DocumentRoot Checking: Under previous versions, when Apache
first started up, it used to do a stat of each DocumentRoot to
see if it existed and was a directory. If not, then an error
message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
does not exist, you will get error messages in error_log. If
the '-t' command line option is used (to check the configuration)
the check of DocumentRoot IS performed. An additional command
line option, '-T', has been added if you want to avoid the
DocumentRoot check even when checking the configuration.
[Jim Jagielski]
*) Win32: The query switch "apache -S" didn't exit after showing the
vhost settings. That was inconsistent with the other query functions.
[Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
*) Win32: Changed behaviour of apache -k restart.
Previously, the server would drain all connections in the stack's
listen queue before honoring the restart. On a busy server, this
could take hours. Now, a restart is honored almost immediately.
All connections in Apache's queues are handled but connections in
the stack's listen queue are discarded. Restart triggered by
MaxRequestPerChild is unchanged.
[Bill Stoddard <stoddard raleigh.ibm.com>]

*) Remove "mxb" support from mod_negotiation -- it was a draft feature
never accepted into any standard, and it opens up certain DoS
attacks. [Koen Holtman <Koen.Holtman cern.ch>]
*) TestCompile updated. We can now run programs and output the
results during the Configure process. [ Jim Jagielski]
*) The source is now quad (long long) aware as needed. Specifically,
the Configure process determines the correct size of off_t and
*void. When the OS/platform/compiler supports quads, ap_snprintf()
provides for the 'q' format qualifier (if quads are not available,
'q' is silently "demoted" to long). [Jim Jagielski]
*) When the username or password fed to htpasswd is too long, include the
size limit in the error message. Also report illegal characters
(currently only ':') in the username. Add the size restrictions
to the man page. [Ken Coar]
*) Fixed the configure --without-support option so it doesn't result in
an infinite loop. [Marc Slemko]
*) Piped error logs could cause a segfault if an error occured
during configuration after a restart.
[Aidan Cully <aidan panix.com>] PR#4456
*) If a "Location" field was stored in r->err_headers_out rather
than r->headers_out, redirect processing wouldn't find it and
the server would core dump on ap_escape_html(NULL). Check both
tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
if Location isn't set. [Doug MacEachern, Ken Coar]
*) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
of the Expat 1.0.2 distribution. [Greg Stein]
*) Replace regexec() calls with calls to a new API stub function
ap_regexec(). This solves problems with DSO modules which use the regex

*) PORT: Add initial support for Mac OS (versions 10.0 and
greater). Use Mac OS X Server layout for now. Clean up dyld code
in unix/os.c, and don't install the dyld error handlers, which
are no longer needed in Mac OS. [Wilfredo Sanchez]
*) Rename Rhapsody layout to "Mac OS X Server". Change install
locations to appropriate ones for user-built (as opposed to
system) installs. [Wilfredo Sanchez]
*) Modify mod_autoindex's handling of AddDescription so that the
behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
*) Add functionality to the install-bindist.sh script created by
binbuild.sh to use tar when copying distribution files to the
serverroot. This allows upgrading an existing installation
without nesting the new distribution in the old.
install-bindist.sh now detects the local perl5 path to install
apxs and dbmmanage with proper path to perl interpreter.
Add an install-binsupport target which copies the source files
for apxs and dbmmanage to bindist to allow these scripts to
be properly installed relative to the destination serverroot.

a) the htdigest utility overwrote the old contents of the digest file
b) the Content-MD5 header value (ContentDigest directive) was wrong
when the returned file was not converted from EBCDIC, but was a
binary (e.g., image file) in the first place.
[David McCreedy at IBM]
*) support/htpasswd now permits the password to be specified on the
command line with the '-b' switch. This is useful when passwords
need to be maintained by scripts -- particularly in the Win32
environment. [Ken Coar]
*) Win32: Win32 multiple services patch. Added capability to install and
run multiple copies of apache as individual services.
Example 1:
apache -n apache1 -i -f c:/httpd.conf
Installs apache as service 'apache1' and associates c:/httpd.conf
with that service.
net start apache1
Starts apache1 service.
net stop apache1
Stops apache1 service
Example 2:
apache -n apache2 -i
Installs apache as service 'apache2'. httpd.conf is located under
the default server root (/apache/conf/httpd.conf).
net start apache2
Starts apache2 service.
Example 3:
apache -n apache3 -i -d c:/program files/apache
Install apache as service 'apache3' and sets server root to
c:/program files/apache.
Example 4:
apache -n apache2 -k restart
Restart apache2 service
[Keith Wannamaker, Ken Parzygnat, Bill Stoddard]
*) Correct the signed/unsigned character handling for the MD5 routines;
mismatches were causing compilation problems with gcc -pedantic and
in the TPF cross-compilation. [Ken Coar]
*) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
a roughly 5 fold speed up. [Brian Havard]
*) proxy ftp: instead of using the hardwired string "text/plain" as
a fallback type for files served by the ftp proxy, use the
ap_default_type() function to determine the configured type.
This allows for special configurations like
<Directory proxy:ftp://some.host>
DefaultType gargle/blurb
</Directory>
Additionally, add the Content-Encoding: header to FTP proxy replies
when the encoding is defined (by the AddEncoding directive).
Because it was missing, it was almost impossible to browse compressed
files using the FTP proxy (works now perfectly in Communicator).
The ftp proxy now also returns the Date: and Server: header lines (if not
much else... This code is "somewhat" broken) like normal requests do.
[Martin Kraemer]
*) Be more smart in APACI's configure script when determining the UID/GID
for User/Group directives and use the determined UID/GID to initialize
the permissions on the proxycachedir.
[Dirk-Willem van Gulik, Ralf S. Engelschall]
*) Changed the forking-prior-to-cleanup in the proxy module to first
check wether it actually needs to collect garbage. This reduces
the number of fork()s from one/request to just the odd one an hour.
[Dirk-Willem van Gulik]
*) Added proxy, auth and header support to src/support/ab.c. Added a
README file to src/support/
[Dirk-Willem van Gulik]

correctly check for output errors and mark the connection as aborted.
Replaced many direct (unchecked) calls to ap_b* routines with the
analogous ap_r* calls. [Roy Fielding]
*) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
DBM format mapfiles now uses a 4-way hash table with LRU functionality.
Furthermore map lookups for non-existent keys are now cached as well.
Additionally "txt" maps are now parsed with simple string functions
instead of using ap_pregcomp(). As a side effect a bug that prevented
the usage of keys containing the "," character was fixed.
The changes drastically improve the performance when large rewrite maps
are in use.

the user to assign authentication control to any HTTP method that
is *not* given in the argument list; i.e., the logical negation
of the <Limit> directive. This is particularly useful for controlling
access on methods unknown to the Apache core, but perhaps known by
some module or CGI script. [Roy Fielding, Tony Finch]
*) Prevent apachectl from complaining if the PIDFILE exists but
does not contain a process id, as might occur if the server is
being rapidly restarted. [Wilfredo Sanchez]
*) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
*) Entity tag comparisons for If-Match and If-None-Match were not being
performed correctly -- weak tags might cause false positives. Also,
strong comparison wasn't properly enforced in all cases.

*) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
[Brian Havard]
*) Work around a bug in Lynx regarding its sending "Negotiate: trans"
even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
*) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
to util.c for parsing an HTTP header field value to extract the next
list item, taking into account the possible presence of nested comments,
quoted-pairs, and quoted-strings. ap_get_list_item() also removes
insignificant whitespace and lowercases non-quoted tokens.
[Roy Fielding] PR#2065
*) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
code different from 500. This allows the proxy to, e.g., return
"403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
*) Fix ordering of language variants for the case where the traditional
negotiation algorithm is being used with multiple language variants
and no Accept-Language. [James Treacy <treacy debian.org>] PR#3299, 3688
*) Do not round the TCN quality calculation to 5 decimal places,
unlike RFC 2296, because the calculation might need 12 decimal places
to get the right result. [Roy Fielding]
*) Remove unused code to disable transparent negotiation when
negotiating on encoding only, as we now handle encoding too
(though this is nonstandard for TCN), remove charset=ISO-8859-1
fiddle from the fiddle-averse RVSA comparison, and fix bugs in
some debugging statements within mod_negotiation. [Koen Holtman]
*) Fixed a rare memory corruption possibility in mod_dir if the index
file is negotiable and no acceptable variant can be found.
[Dean Gaudet, Roy Fielding, Martin Kraemer]
*) Win32: Add new config directive, ScriptInterpreterSource, to enable
searching the Win32 registry for script interpreters.
[Bill Stoddard]
*) Win32: The compiled-in default filename for the error log is now
error.log, which matches the default in the distributed httpd.conf.
[Paul Sutton]
*) Win32: Any error messages from -i or -u command line options are now
displayed on the console output rather than sent to the error log.
Also the "Running Apache..." message is not output unless Apache is
going to serve requests. [Paul Sutton]
*) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
and use a private significator ('$apr1$') to mark passwords as
being smashed with our own algorithm. Also abstract the password
checking into a new ap_validate_password() routine. [Ken Coar]
*) Win32: The filename validity checker now allows "COM" but refuses
access to "COM1" through "COM4". This allows filenames such
as "com.name" to be served. [Paul Sutton] PR#3769.
*) BS2000: Adapt to the new ufork() system call interface which will
make subtasking easier on the OSD/POSIX mainframe environment.
[Martin Kraemer]
*) Add a compatibility define for escape_uri() -> ap_escape_uri() to
ap_compat.h. [David White <david persimmon.com>] PR#3725

[Doug Yatcilla <yatcilda umdnj.edu>] PR#3681
*) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
and check to see if the tar we wind up with supports '-h'.
[Jim Jagielski] PR#3671
*) A consistent and conservative style for all shell scripts has been
implemented. Basically, all shell string tests use the traditional
hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
to protect against bare null variable strings (ie: wrapping both
sides with double quotes and prepending 'x'). 'x' was chosen
because it's more universal and hopefully easier for old shell
prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
[Jim Jagielski]
*) The status module now prints out both the main server generation as
well as the generation of each process. Also, the vhost info is
printed with '?notable'. [Jim Jagielski]
*) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
and this makes its functions available to things in src/support.
[Ken Coar]
Changes with Apache 1.3.4
*) Renamed macros status_drops_connection to ap_status_drops_connection
and vestigial scan_script_header to ap_scan_script_header_err,
mostly for aesthetic reasons. [Roy Fielding]
*) The query switch "httpd -S" didn't exit after showing the
vhost settings. That was inconsistent with the other query functions.
[Martin Kraemer]
*) Moved the MODULE_MAGIC_COOKIE from before the versions and
filename to the end of the STANDARD_MODULE_STUFF. Its
presence at the beginning prevented reporting of the filename
for modules compiled before 1 January 1999. [Ken Coar]
*) SECURITY: ap_os_is_filename_valid() has been added to Win32
to detect and prevent access to special DOS device file names.
[Paul Sutton, Ken Parzygnat]
*) WIN32: Created new makefiles Makefile_win32.txt (normal build)
and Makefile_win32_debug.txt (debug build) that work on Win95.
Run each of the following from the src directory:
nmake /f Makefile_win32.txt # compiles normal build
nmake /f Makefile_win32.txt install # compiles and installs
nmake /f Makefile_win32.txt clean # removes compiled junk
nmake /f Makefile_win32_debug.txt # compiles debug build
nmake /f Makefile_win32_debug.txt install
nmake /f Makefile_win32_debug.txt clean
[Roy Fielding]
*) Added binbuild.sh and findprg.sh helpers to make it easier for us
to build binary distributions. [Lars Eilebrecht]
*) IndexOptions SuppressColumnSorting only turned off making
the column headers anchors; you could still change the display
order by manually adding a '?N=A' or similar query string to the
URL. Now SuppressColumnSorting locks in the sort order so
it can't be overridden this way. [Ken Coar]
*) Added IndexOrderDefault directive to supply a default sort order
for FancyIndexed directory listings. [Ken Coar] PR#1699
*) Change the ap_assert macro to a variant that works on all platforms.
[Richard Prinz <richard.prinz cso.net>] PR#2575
*) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
search for an underscore on dlsym() (as it's already the case
for FreeBSD 3.0). [Todd Vierling <tv pobox.com>] PR#2462
*) Small fix for mod_env.html: The module was documented as to be _not_
compiled into Apache per default, although it _IS_ compiled into
Apache per default. [Sim Harbert <sim mindspring.com>] PR#3572
*) Instead of fixing a bug in the generation procedure for config.status (a
backslash was missing) we remove the bug together with it's complete
context because the special cases of the past can now no longer occur
because of the recent magic for the --with-layout default.
[Ralf S. Engelschall] PR#3590
*) Make top-level Makefile aware of a parallel build procedures (make -j) by
making sure the src/support/ tools are _forced_ to be build last (they
depend on other libraries).
[Markus Theissinger <markus.theissinger gmx.de>]
*) Fix installation procedure: Now that os-inline.c is actually used (a
recently fixed bug prevented this) we need to also install os-include.c
in addition to os.h into the PREFIX/include/ location or building of
module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
*) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
allow us to distinguish between a garbled DSO (or even a file which isn't
an Apache module DSO at all) and a DSO which doesn't match the current
Apache API. [Ralf S. Engelschall] PR#3152
*) Two minor enhancements to mod_rewrite: First RewriteRule now also
supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
match case insensitive (this especially avoids nasty patterns like
`[tT][eE][sS][tT]'). Second two additional internal map functions
`escape' and `unescape' were added which can be used to escape/unescape
to/from hex-encodings in URLs parts (this is especially useful in
combination with map lookups).
[Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
*) Renamed the macro escape_uri() to ap_escape_uri() which was
forgotten (because it was a macro) in the symbol renaming process.
[Ralf S. Engelschall]
*) Fix some inconsistencies related to the scopes of directives. The only
user visible change is that the directives `UseCanonicalName' and
`ContentDigest' now use the (more correct) `Options' scope instead of
(less correct) `AuthConfig' scope. [Ralf S. Engelschall]
*) Using DSO, the Server token was being mangled. Specifically, the
module's token was being added first before the Apache token. This
has been fixed. [Jim Jagielski]
*) Major overhaul of mod_negotiation.c, part 2.
- properly handle "identity" within Accept-Encoding.
- allow encoded variants in RVSA negotiation and let them appear in
the Alternates field using the non-standard "encoding" tag-list.
- fixed both negotiation algorithms so that an explicitly accepted
encoding is preferred over no encoding if "identity" is not
included within Accept-Encoding.
- added ap_array_pstrcat() to alloc.c for efficient concatenation
of large substring sequences.
- replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
[Roy Fielding]
*) Major overhaul of mod_negotiation.c, part 1.
- cleanups to mod_negotiation comments and code structure
- made compliant with HTTP/1.1 proposed standard (rfc2068) and added
support for everything in the upcoming HTTP/1.1
revision (draft-ietf-http-v11-spec-rev-06.txt).
- language tag matching also handles tags with more than 2
levels like x-y-z
- empty Accept, Accept-Language, Accept-Charset headers are
processed correctly; previously an empty header would make all
values acceptable instead of unacceptable.
- allowed for q values in Accept-Encoding
- added support for transparent content negotiation (rfc2295 and
rfc2296) (though we do not implement all features in these drafts,
e.g. no feature negotiation). Removed old experimental version.
- implemented 'structured entity tags' for better cache correctness
(structured entity tags ensure that caches which can deal with Vary
will (eventually) be updated if the set of variants on the server
is changed)
- this involved adding a vlist_validator element to request_rec
- this involved adding the ap_make_etag() function to the global API
- modified guessing of charsets used by Apache negotiation algorithm
to guess 'no charset' if the variant is not a text/* type
- added code to sort multiviews variants into a canonical order so that
negotiation results are consistent across backup/restores and mirrors
- removed possibility of a type map file resolving to another type map
file as its best variant
[Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
*) RFC2396 allows the syntax http://host:/path (with no port number)
but the proxy disallowed it (ap_proxy_canon_netloc()).
[David Kristol <dmk bell-labs.com>] PR#3530
*) When modules update/modify the file name in the configfile_t structure,
syntax errors will report the updated name, not the original one.
[Fabien Coelho <coelho cri.ensmp.fr>] PR#3573
*) Correct some filename case assumptions from WIN32 to
CASE_BLIND_FILESYSTEM. [Brian Havard <brianh kheldar.apana.org.au>]
*) For %v log ServerName regardless of the UseCanonicalName
setting (similarly for %p). [Dean Gaudet]
*) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
rather late (too late for some invocations of TestCompile).
This improves the make environment available to TestCompile and
the *.module scripts. [Martin Kraemer]
*) The hashbang emulation code in ap_execve.c would interpret
#!/hashbang/scripts correctly, but failed to fall back to a
standard shell for scripts which did NOT start with #!
Now SHELL_PATH is started in these cases. [Martin Kraemer]
*) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg lentil.org>]
PR#3336
*) Update APXS manual page: some -q option arguments were missing
and another was incorrect. [Mark Anderson <mda discerning.com>] PR#3553
*) Cleanup the command line options: `-?' was documented to show
the usage list but does it with an error because `?' is not a valid
command. OTOH a lot of users expect `-h' to print such a usage list and
instead are annoyed for ages by our huge unreadable list of directives.
So we now changed the command line options this way:
1. `-L' => `-R'
Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
very similar to the popular linker option.
2. `-h' => `-L'
Intent: while -l gives the small list of modules, -L now gives the
large list of directives implemented by these modules. This is also
consistent with -v (short version info) and -V (large version info).
3. `-?' => `-h'
Intent: it's now the expected option ;-)
The manual page was adjusted accordingly.
[Ralf S. Engelschall] PR#2714
*) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
wasn't defined. [Rick Franchuk <rickf transpect.net>]
*) Removed recently introduced bugs and disfigurements in APACI:
o fixed argument line processing: using $args was broken: It was not
initialized and using args="$args $apc_option" and even args="$args
\"$apc_option\"" fails in the second processing round for any arguments
containing whitespaces. The only correct way is to use the construct
"$@" (but not possible here) or iterate _both_ times over the implicit
argument line (no argument to for-loop) which is what we now use.
o make --with-layout=Apache the default without creating
redundancy (copying the --with-layout block in the argument parsing
loop). We achieve this by using the "$@" construct together with the
`set' command to prepend --with-layout=Apache to the command line in
case --with-layout is not used.
o fixed auto-suffix handling now that config.layout exists.
Paths which are auto-suffixed are marked with a trailing plus sign in
config.layout and every path now can be marked this way (not only the
four paths for which we do it currently). Additionally the suffix is
no longer a static one. Instead it's now `/<target>' where <target> is
the argument of the --target option or per default `httpd'.
o allow also tabs (and only spaces) where we match whitespaces
o various fixes and cleanups related to used shell coding style
o made Jim happy by replacing `Written by' with `Initially written by' ;-)
o trimmed output of --help to fit into 80 columns
[Ralf S. Engelschall]
*) Added two new core API functions, ap_single_module_configure() and
ap_single_module_init(), which are now used by mod_so to configure a module
after loading. [Ralf S. Engelschall]
*) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
of ap_config.h to allow serialized accept for multiport listens.
[Roy Fielding, Curt Sampson] PR#3120
*) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
of ap_config.h that would skip several defines if DEFAULT_GROUP
was overridden. [Roy Fielding]
*) PORT: The I86 version of DGUX has support for strncasecmp and
strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
*) Fix ordering of definitions in ap_config.h so that ap_inline is
defined before it might be used. [Victor Khimenko]
*) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
[Tom Serkowski <tks bsdi.com>] PR#3453
*) Make generation of src/Configuration.apaci more robust: It failed to
differenciate between modules when one module name was a postfix of
another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
just XXX (think about totally non-standard names like "apache_ssl", too).
[Ralf S. Engelschall] PR#3380
*) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
since 1.3b7) and make whitespace handling more robust (it failed horrible
when whitespaces were present in the arguments of -D options).
[Ralf S. Engelschall] PR#3240
*) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
creates an external package shadow tree in DIR before the local build
shadow tree is generated under DIR. This way one can have the extracted
Apache distribution tree read-only on NFS or CDROM and still build Apache
from these sources. An automatically triggered VPATH-like mechanism is
provided through the TOP variable, too.
[Ralf S. Engelschall, Wilfredo Sanchez <wsanchez apple.com>]
*) Fix negotiation so that a Vary response header is correctly
generated when, for a particular dimension, variants only vary
in having or not having a value for that dimension. [Paul Sutton]
*) Fix negotiation so that we prefer an encoded variant over an
unencoded variant if the user-agent explicitly says it can
accept that encoding. Previously we always preferred the unencoded
variant.
[Paul Ausbeck <paula alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
*) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
and the usage page was inconsistent with the functionality and manpage.
[Ralf S. Engelschall]
*) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
They can occur multiple times and their arguments (`xxx') are passed AS
IS to the compiler/linker command. [Ralf S. Engelschall]
*) Fixed possible (but harmless in practice) bug in the DBM lookup
procedure of mod_rewrite: very long keys were truncated.
[Ralf S. Engelschall]
*) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
identifier, currently "Apache" and "GNU" are pre-defined in the file
config.layout. Custom layouts are possible by using FILE:ID as the
argument where the layout ID is taken from FILE.
The config.layout file consists of <Layout ID>..</Layout> sections
where inside those sections "path_variable: path_value" pairs can be
specified. These lines are converted to path_variable='path_value'.
*) Add a DefaultLanguage directive so that files missing a language
extension (e.g., .fr, .de) can be labelled as being some other
default language. DefaultLanguage can appear in <Directory> and
<Files> containers as well as .htaccess files. [Paul Sutton]
PR#1180
*) Fix TARGET configuration when configuring and installing using
APACI configure. TARGET now defines the basename of the configuration
file, startup script, manual page, etc. log_error_core() now reports
the server binary name given by argv[0]. TARGET can now also be defined
with --target=TARGET parameter passed to APACI configure.
[Ralf Engelschall, Randy Terbush]
*) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
rather than OPT_INCLUDES [Rainer Schoepf <schoepf uni-mainz.de>]
*) ap_md5_binary() was using sprintf() rather than a table lookup
to convert binary bytes to hex digits.
[Ronald Tschalär <ronald innovation.ch>] PR#3409
*) Fix SEGV in TCN negotiation if no variants are acceptable.
[Martin Plechsmid <plechsmi karlin.mff.cuni.cz>] PR#1987
*) API: ap_exists_config_define() function is now "public" [Doug MacEachern]
*) Fix documentation of `Action' directive: It can activate a CGI script
when either a handler or a MIME content type is triggered by the request.
[Andrew Pimlott <pimlott math.harvard.edu>] PR#3340
*) Document the `add' command of `dbmmanage' in `dbmmanage.1' manpage.
[David MacKenzie <djm uu.net>] PR#3394
*) Ignore a "ErrorDocument 401" directive with a full URL and write a
notice to the error log. It is not possible to send a 401 response
and a redirect at the same time. [Lars Eilebrecht]
*) Fallback to native compilers for IRIX-32 platform. It seems that
a gcc 2.8.1 compiled apache is logging client addresses with all
bits set (255.255.255.255). This is the second such problem caused
by gcc 2.8.1 compiler. The first being broken semaphore locking.
[Randy Terbush]
*) Updated mime.types to reflect current Internet media types
and include a URL to the registry.
[Manoj Kasichainula, Roy Fielding] PR#2380, 2286, 2246
*) SECURITY: Do a more complete check in mod_include to avoid
an infinite loop of recursive SSI includes. [Marc Slemko] PR#3323
*) Add APACI --suexec-docroot and --suexec-logfile options which can be
used to set the document root directory (DOC_ROOT) and the suexec
logfile (LOG_EXEC), respectively. Additionally the --layout option
was changed to show more information about the suEXEC setup.
[Lars Eilebrecht] PR#3316, 3357, 3361
*) Added the last two WebDAV status codes of 424 (Failed Dependency)
and 507 (Insufficient Storage) for use by third-party modules.
[Roy Fielding]
*) Enabled all of the WebDAV method names for use by third-party
modules, Limit, and Script directives. That includes PATCH,
PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.
Improved mod_actions.c so that it can use any of the methods
defined in httpd.h. Added ap_method_number_of(method) for
getting the internal method number. [Roy Fielding]

*) Disable sending of error-notes on a 500 (Internal Server Error) response
since it often includes file path info. Enable sending of error-notes
on a 501 (Method Not Implemented). [Roy Fielding] PR#3173
*) http_config.c would respond with 501 (Method Not Implemented) if a
content type handler was specified but could not be found, which
should have been a 500 response. Likewise, mod_proxy.c would responsd
with a 501 if the URI scheme is unrecognized instead of the correct
response of 403 (Forbidden). [Roy Fielding]
*) SECURITY: Eliminate DoS attack when a bad URI path contains what
looks like a printf format escape. [Marc Slemko, Studenten Net Twente]
*) Fix in mod_autoindex: for files where the last modified time stamp was
unavailable, an empty string was printed which was 2 bytes short.
The size and description columns were therefore not aligned correctly.
[Martin Kraemer] (no PR#)
*) Update BS2000 OS code to work with recent versions. Starting with
release A17, the child fork() must be replaced by a _rfork().
(BS2000 only) [Martin Kraemer]
*) Add the actual server_rec structure of the specific Vhost to the
scoreboard file and avoid a string copy (as well as allow some
further future enhancements). [Harrie Hazewinkel
<harrie.hazewinkel jrc.it>]
*) Add APACI --permute-module=foo:bar option which can be used to
on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
in the Configuration[.apaci] file. Two special and important variants are
supported for the option argument: first BEGIN:foo which permutes module
mod_foo with the begin of the module list, i.e. it `moves' the module to
the begin of the list (gives it lowest priority). And second foo:END
which permutes mod_foo with the end of the module list, i.e. it `moves'
the module to the end of the list (gives it highest priority).

Changes with Apache 1.3.3
*) Added a complete implementation of the Expect header field as
specified in rev-05 of HTTP/1.1. Disabled the 100 Continue

useful for PUT responses that result in 302 or 401. [Roy Fielding]
*) Remove extra trailing whitespace from the getline results as part
of the protocol processing, which is extra nice because it works
between continuation lines, is almost no cost in the normal case

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

*) mod_expires will now act on content that is not sent from a file

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

[Brian Havard, Ralf S. Engelschall]
*) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
files (here modules) against other DSO files (here shared libraries).
This is done by determining a subset of LIBS which can be safely used for
linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
disabled for all platforms to avoid problems with this (experimental)
rule. But we provide it now for those people how ran into problems and
want to came out by forcing linking against DSOs.

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

those esoteric ones.

*) WIN32 SECURITY: Eliminate trailing "."s in path components. These are
ignored by the Windows filesystem, and so can be used to bypass security.

*) We now attempt to dump core when we get SIGILL. [Jim Jagielski]
*) PORT: remove broken test for MAP_FILE in http_main.c.
[Wilfredo Sanchez <wsanchez apple.com>]
*) PORT: Change support/apachectl to use "kill -0 $pid" to test if the
httpd is running. This should be more portable than figuring out
which of three dozen different versions of "ps" are installed.
[a cast of dozens]
*) WIN32: If we can't figure out how to execute a file in a script
directory, bail out of the request with an error message. [W G Stoddard]
*) WIN32 SECURITY: Eliminate directories consisting of three or more dots;
these are treated by Win32 as if they are ".." but are not detected by
other machinery within Apache. This is something of a kludge but
eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
*) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
pools and thus pollutes libap (until the pool stuff is moved there).
[Ken Coar]
*) IndexIgnore should be case-blind on Win32 (and any other case-aware
but case-insensitive platforms). New #define for this added to conf.h
(CASE_BLIND_FILESYSTEM). [Ken Coar] PR#2455

also works for OpenBSD 1.x. [Ralf S. Engelschall]
*) PORT: Fix compilation problem on ARM Linux.
[Sam Kington <sam illuminated.co.uk>] PR#2443
*) Let APACI's configure script determine some configuration parameters
(Group, Port, ServerAdmin, ServerName) via some intelligent tests to
remove some of the classical hurdles for new users when setting up
Apache. This is done per default because it is useful for the average
user. Package authors can use the --without-confadjust option to disable
these configuration adjustments.
[Ralf S. Engelschall]
*) Added an EXTRA_DEPS configuration parameter which can be used
to add an extra Makefile dependency for the httpd target, for instance
to external third-party libraries, etc.
[Ralf S. Engelschall]
*) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
as <IfModule>..</IfModule> sections) which can be used to skip or process
contained commands dependend of ``-D PARAMETER'' options on the command
line. This can be used to achieve logical conditions like <IfDefine
ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
and thus especially can be used for conditionally loading DSO-based
modules via LoadModule, etc. [Ralf S. Engelschall]
*) PORT: clean up a warning in mod_status for OS/2. [Brian Havard]
*) Make table elements const. This may prevent obscure errors. [Ben Laurie]

truncated which forced following HTTP headers to be data in the HTTP
reponse. [Ralf S. Engelschall, Charles Fu <ccwf bacchus.com>]
PR#2412, 2367
*) Portability fix for APACI shadow tree support: Swap order of awk and sed
in top-level configure script to avoid sed fails on some platforms (for
instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
output of Awk. [Bill Houle <bhoule sandiegoca.ncr.com>] PR#2435
*) Improve performance of directory listings (mod_autoindex) by comparing
integer keys (last-modified and size) as integers rather than converting
them to strings first. Also use a set of explicit byte tests rather
than strcmp() to check for parent directory-ness of an entry. Oh, and
make sure the parent directory (if displayed) is *always* listed first
regardless of the sort key. Overall performance winnage should be good
in CPU time, instruction cache, and memory usage, particularly for large
directories. [Ken Coar]
*) Add a tiny but useful goody to APACI's configure script: The generation
of a config.status script (as GNU Autoconf does) which remembers the used
configure command and hence can be used to restore the configuration by
just re-running this script or for remembering the configuration between
releases.
[Ralf S. Engelschall]
*) Add httpd -t (test) option for running configuration syntax tests only.
If something is broken it complains and exits with a return code
non-equal to 0. This can be used manually by the user to check the Apache
configuration after editing and is also automatically used by apachectl
on (graceful) restart command to make sure Apache doesn't die on restarts
because of a configuration which is now broken since the last (re)start.
This way `apachectl restart' can be used inside cronjobs without having
to expect Apache to be falling down. Additionally the httpd -t can be run
via `apachectl configtest'.

[Ralf S. Engelschall] PR#2378
*) Make sure the "install" target of the top-level Makefile doesn't break
because of a return code of 1 from an "if" (for instance under braindead
Ultrix the result code of an "if" construct is 1 if the "then" clause
didn't match). [Ralf S. Engelschall]
*) Add an additional "dummy" target to the "$(LIB)" target in generated
modules/xxx/Makefile's to avoid problems with SVR4 Make under "full-DSO"
situation (no libxxx.a built, only mod_xxx.so's) where LIB and OBJS are

[W G Stoddard <wgstodda us.ibm.com>] PR#2294
*) Some symbol renaming:
ap_spawn_child_err became ap_spawn_child
ap_spawn_child_err_buff became ap_bspawn_child
spawn_child was obsoleted and moved to compat.h
[Brian Behlendorf]
*) Upgrade the child spawning code in mod_rewrite for the RewriteMap
programs: ap_spawn_child_err() is used and the Win32 case now uses
CreateProcess() instead of a low-level execl() (which caused problems in
the past under Win32).
[Ralf S. Engelschall]
*) A few cosmetics and trivial enhancements to APXS to make the
generated Makefile more user friendly. [Ralf S. Engelschall]
*) Proxy Fix: The proxy special failure routine ap_proxyerror()
was updated to use the normal apache error processing, thereby allowing
proxy errors to be treated by ErrorDocument's as well. For this
purpose, a new module-to-core communication variable "error-notes"
was introduced; the proxy (and possibly other modules) communicates
its error text using this variable. Its content is copied to a new
cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
The old proxy special error routine ap_proxy_log_uerror()
was replaced by regular ap_log_error() calls, many messages were made
more informative.
[Martin Kraemer] PR#494, 1259
*) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
[Martin Kraemer]
*) Transform the configure message "You need root privileges for suEXEC"
from a fatal error into a (more friendly) warning because the building
("make") of Apache we can allow, of course. Root privileges are needed
only for the installation step ("make install"). So make sure the
user is aware of this fact but let him proceed as long as he can.
[Ralf S. Engelschall] PR#2288
*) Renamed three more functions to common ap_ prefix which we missed at the
Big Symbol Renaming because they're #defines and not real C functions:
is_default_port(), default_port(), http_method().
[Ralf S. Engelschall]
*) A zero-length name after a $ in an SSI document should cause
just the $ to be in the expansion. This was broken during the

used under AIX) because of recent changes to function names.
[Ralf S. Engelschall]
Changes with Apache 1.3b7
*) Make sure a MIME-type can be forced via a RewriteRule even when no
substitution takes place, for instance via the following rule:
``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
requested by users in the past to force a single script without a .cgi
extension and outside any cgi-bin dirs to be executed as a CGI program.
[Ralf S. Engelschall] PR#2254
*) A fix for protocol issues surrounding 400, 408, and

trying to connect to certain ftpd's, such as anonftpd.
[Rick Ohnemus <rick ecompcon.com>]
*) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
logfile instead of fiddling around itself with child spawning stuff.
[Ralf S. Engelschall]
*) Made RefererIgnore case-insensitive.
*) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
[Brian Behlendorf]

[Ralf S. Engelschall] PR#2242
*) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
[Ben Laurie] PR#2238
*) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
library), so CGI handling has been changed to use Win32 native handles
instead of C file descriptors.
[Ben Laurie and Bill Stoddard <wgstodda us.ibm.com>] PR#1129, 1607
*) The proxy cache would store an incorrect content-length in the cached
file copy after a cache update. That resulted in repeated fetching
of the original copy instead of using the cached copy.
[Ernst Kloppenburg <kloppen isr.uni-stuttgart.de>] PR#2094
*) The Makefiles assumed that DSO files are build via $(LD). This
is broken for two reasons: First we never defined at least LD=ld
somewhere to make sure this works (it was silently assumed that most Make
provide a built-in LD definition - ARGL!) and second using the generic LD
variable is not the truth. Instead a special variable named LD_SHLIB is
reasonable because although "ld" is usually the default, the command for
building DSO files can be "libtool" or even "cc" on some systems.
[Ralf S. Engelschall]
*) Replace the AddVersionPlatform directive with ServerTokens which
provides for more control over the format of the Server:
header line. SERVER_SUBVERSION is no longer supported;
all module should use the ap_add_version_component()
API function instead. [Jim Jagielski]
*) Support for the NCR MP/RAS 3.0
[John Withers <withers semi.kcsc.mwr.irs.gov>]
*) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
not retrieved in src/Configure and thus was not useable.
[Ralf S. Engelschall]
*) Various Makefile consistency cleanups:
- make OSDIR also automatically be relative to src/ like INCDIR
- SUBDIRS is now generated in src/Makefile only and not in
Makefile.config because it is a local define for this location.
- remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
any Makefile but make sure that at least the "-K inline" is kept in
CFLAGS for SCO 5.
- update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
- updated the dependencies theirself
- removed not existing SHLIB variable from "clean" targets
- replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
already exists and OBJS_PIC are also just plain objects and have not
directly to do with "shared" things. The only difference is that they
contain PIC. So OBJS_PIC is the more canonical name.
- Updated the Makefile-dependency lines for OBJS_PIC
- Removed the Makefile-dependency line in Configure to avoid double
definitions
- replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
of xxx.lo as GNU libtool does with its PIC objects
- reduce local complexity in modules Makefile.tmpl by moving the last
existing target "depend" to the generation section in Configure, too.
- removed the historical $(SPACER) which was used in the past together
with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
is no longer needed.
- force the build and run of the gen_xxx programs under main/ as the
first step before building the objects because it looks cleaner
[Ralf S. Engelschall]
*) WIN32: Make Win32 work again after the /dev/null DoS fix.
[Ben Laurie]
*) WIN32: Check for buffer overflows in ap_os_canonical_filename.
[Ben Laurie]
*) WIN32: Don't force ISAPI headers to finish with \n.
[Jim Patterson <Jim.Patterson Cognos.COM>, Ben Laurie] PR#2060
*) When opening "configuration" files (like httpd.conf, htaccess
and htpasswd), Apache will not allow them to be non-/dev/null
device files. This closes a DoS hole. At the same time,
we use ap_pfopen to open these files to handle timeouts.
[Jim Jagielski, Martin Kraemer]
*) Apache will now log the reason its httpd children exit if they exit
due to an unexpected signal. (It requires a new porting define,
SYS_SIGLIST, which if defined should point to a list of text
descriptions of the signals available. See PORTING.) [Dean Gaudet]
*) WIN32: chdir() doesn't make sense in a multithreaded environment
like WIN32. Before, Win32 CGI's could have had sporadic failures
if a chdir call from one thread was made between another chdir call
and a spawn in another thread. So, for now don't chdir for CGI scripts
in WIN32. The current CGI "spec" is unclear as to whether it's
necessary. Long-term fix is to either serialize the chdir/spawn combo
or use WIN32 native calls to spawn a process. This temp fix was
necessary to remove this as a showstopper for 1.3's release.
[Brian Behlendorf]
*) Cleanup the suEXEC support in APACI and make it more safe:
1. Add big fat hint in INSTALL about risks and to read the
htdocs/manual/suexec.html document before using the suexec-related
configure options.
2. Make sure the user has at least provided one --suexec-xxxx option
(specifies suEXEC parameters) in addition to --enable-suexec option.
If only --enable-suexec is given APACI stops with a hint to INSTALL
and htdocs/manual/suexec.html documents.
3. Provide two additional --suexec-xxxx options to make the suEXEC
configuration complete (especially for package maintainers who else
had to patch the source tree) by providing ways to configure minimal
UID/GID and safe PATH, too.
[Ralf S. Engelschall]
*) Cleanup of the `configure --shadow' process:
- make sure the configure script creates its temporary files in the
shadow tree to avoid conflicts with parallel configure runs
- removed unnecessary option "-r" from "rm" call for Makefiles
- make sure the configure scripts creates the shadow-wrapper Makefile
only when no shadow trees already exists
- make sure "make distclean" removes the shadow-wrapper Makefile but only
when no more shadow trees exists
- overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
as fast (in the past it needed 70sec, now it runs just 38sec)
- make sure CVS does not complain about the created files
Makefille.<gnutriple> and directories src.<gnutriple>
[Ralf S. Engelschall]
*) Added the ap_add_version_component() API routine and the
AddVersionPlatform core directive. The first allows modules to
declare themselves in the Server response header field value,
augmenting the SERVER_SUBVERSION define in the Configuration file
with run-time settings (more useful in a loadable-module environment).
AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
into the server version string. [Ken Coar] PR#2056
*) Minor stability tweaks to avoid core dumps in ap_snprintf.
[Martin Kraemer]
*) Emit the "Accept-Range" header for the default handler.
[Brian Behlendorf] PR#1464
*) Add a note to httpd.conf-dist that apache will on some systems fail
to start when the Group # is set to a negative or large positive value.
[Martin Kraemer]
*) Make sure the module execution order is correct even when some modules
are loaded under runtime (`LoadModule') via the DSO mechanism:
1. The list of loaded modules is now a dynamically allocated one
and not the original statically list from modules.c
2. The loaded modules are now correctly setup by LoadModule for
later use by the AddModule command.
3. When the DSO mechanism for modules is used APACI's `install'
target now enables all created `LoadModule' lines per default because
this is both already expected by the user _and_ needed to avoid
confusion with the next point and reduces the Makefile.tmpl complexity
4. When the DSO mechanism for modules is used, APACI's `install'
target now additionally makes sure the module list is reconstructed
via a complete `ClearModuleList+AddModule...' entry.
5. The support tool `apxs' now also makes sure an AddModule command
is added in addition to the LoadModule command.
6. The modules.c generation was extended to now contain two
comments to make sure no one is confused by the confusing terminology
of loading/linking (we use load=link+load & link=activate instead of
the obvious load=activate & link=link :-( )
This way now there is no longer a difference under execution time between
statically and dynamically linked modules.
[Ralf S. Engelschall]

because if there's no Port directive in the config r->server->port is 0.

Additionally the checks for finding the vendor DSO library were moved

mod_so already uses an abstraction layer and does not fiddle with the
vendor functions itself.
[Jens-Uwe Mager, Ralf S. Engelschall]
*) PORT: Some optimization defines for NetBSD
[Jaromir Dolecek <dolecek ics.muni.cz>] PR#2165
*) PORT: Dynamic Shared Object (DSO) support for NetBSD.
[Jaromir Dolecek <dolecek ics.muni.cz>, Ralf S. Engelschall] PR#2158
*) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
AIX variants should work fine, too. Even AIX 3.x should work). This is
accomplished by using the free DSO emulation code from Jens-Uwe Mager
which we put into a os/unix/os-dso-aix.c file.
[Ralf S. Engelschall]
*) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply

[Roy Fielding]
*) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
is unset (as it is in situations like timeouts) where it is unclear
whether errno is set or not. [Martin Kraemer]
*) Just having APACI's localstatedir is too general and not enough for most
of the systems. 1.3b6 again required manual APACI patches by package
maintainers from Red Hat and FreeBSD because for their filesystem layout a
little bit more flexibility in configuring the paths is needed. Hence we
provide three additional configure options (--runtimedir, --logfiledir,
--proxycachedir) which now can be used for more granular adjustments if
--localstatedir is not enough to fit the particular needs. As a nice
side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
[Ralf S. Engelschall]
*) Make the install root for "make install" in APACI's Makefile overrideable
by package authors. This way we are even more friendly to package
maintainers (especially Debian and Red Hat) who build for the real prefix
via "configure --prefix=/<real>" but use a different local prefix via
"make root=/tmp/apache install" for rolling the package without bristling
the target location on their system.

(Other dumps may be added in the future.) [Dean Gaudet]
*) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
ap_snprintf, and ap_psprintf). See include/ap.h for docs.
[Dean Gaudet]
*) Because /usr/local/apache is the default prefix the ``configure

*) ++++ THE BIG SYMBOL RENAMING ++++
To avoid symbol clashes with third-party code compiled into the server,
we globally applied the prefix "ap_" to the following classes of
functions:
- Apache provided general functions (e.g., ap_cpystrn)
- Public API functions (e.g., palloc, bgets)
- Private functions which we can't make static (because of
cross-object usage) but should be (e.g., new_connection)
For backward source compatibility a new header file named compat.h was
created which provides defines for the old symbol names and can be used
by third-party module authors.
[The Apache Group]
*) Added dynamic shared object (DSO) support for SVR4-derivates: The
problem under SVR4 is that there is no command flag to force the linker
to export the global symbols of the httpd executable therewith they are
available to the DSO's. Instead of problematic hacks like creating a
dummy.so file (containing dummy references to all global symbols) the
httpd binary is linked against, we use a clean trick stolen from Perl 5:
Placing the Apache core code itself into a DSO library named libhttpd.so.
This way the global symbols _HAVE_ to be exported and thus are available
to any manually loaded DSO's under runtime. To reduce the impact to the
user to null we go even further and create a stub httpd executable which
automatically keeps track of the DSO library loading itself and thus
hides the complete mechanism from the user. Although the generation of
this DSO library is automatically triggered for platforms which
essentially need it (mostly all SVR4-derivates) it can be also enabled
manually via the Rule SHARED_CORE. This can be interesting in the future
where we perhaps exploit this libhttpd.so mechanism for providing nifty
features like graceful upgrades, or whatever.
[Ralf S. Engelschall, Martin Kraemer]
*) Build the libraries before building the rest of the tools. [Ben Hyde]
*) Add "distclean" target to src/-Makefiles to provide "make distclean" also
inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
conventions while "clean" removes only stuff created by "all" targets,
"distclean" additionally removes the stuff from the configuration
process. This way "make distclean" (hence the name) provides a fresh
source tree as it was for distribution.
[Ralf S. Engelschall]
*) Allow top-level (APACI) Makefile to break on build errors
the same way the src/ subtree Makefiles breaks on them by replacing the
initial APACI sed-subdir-display-kludge with a more clean
variable-passing-solution: variable SDP can optionally hold the subdir
prefix which is consistently used for displaying the subdir movement.
This way even the top-level Makefile can stop correctly on errors as the
user expects. [Ralf S. Engelschall]
*) Fixed ordering of argument checks for RewriteBase directive.
[Todd Eigenschink <eigenstr mixi.net>] PR#2045
*) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
indicating that a module is being compiled for dynamic loading. Also
remove #define IS_MODULE from modules and add SHARED_MODULE define
to the mak/dsp files. [Alexei Kosut]
*) Reduce logging level of "normal" warning messages to APLOG_INFO,
since we are now logging APLOG_WARNING by default. [Roy Fielding]
*) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
*) Add documentation file and src/Configuration.tmpl entry for the
experimental mod_mmap_static module. Because although it is and marked as
an experimental one it is distributed and thus should be documented and
prepared for configuration the same way as all others modules.
[Ralf S. Engelschall]
*) Add query (-q) option to apxs support tool to be able to manually query
specific settings from apxs. This is needed for instance when you
manually want to access Apache's header files and you need to assemble
the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
[Ralf S. Engelschall]
*) Now src/Configure uses a fallback strategy for the shared object support
on platforms where no explicit information is available: If a Perl
installation exists we ask it about its shared object support and if it's
the dlopen-style one we shamelessly guess the compiler and linker flags
for creating shared objects from Perls knowledge. Of course, the user is
warning about what we are doing and informed that he should send us
the guessed flags when they work. [Ralf S. Engelschall]
*) Provide APACI --without-support option to be able to disable the build
and installation of the support tools from the src/support/ area.
Although its useful to have these installed per default we should provide
a way to compile and install without them for backward-compatibility.
[Ralf S. Engelschall]
*) Add of the new APache eXtenSion (apxs) support tool for building and
installing modules into an _already installed_ Apache package through the
dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
this approach actually doesn't need the Apache source tree. The
(APACI-installed) server package is enough, because this now includes the
Apache C header files (PREFIX/include) and the new APXS tool
(SBINDIR/apxs). The intend is to provide a handy tool for third-party
module authors to build their Apache modules _OUTSIDE_ the Apache source
tree while avoiding them to fiddle around with the totally platform
dependend way of compiling DSO files. The tool supports all ranges of
modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
on-the-fly generate a minimalistic Makefile and sample module for the
first step to provide both a quick success event and to demonstrate the
APXS mechanism to module authors. [Ralf S. Engelschall]
*) Fix core dumps in use of CONNECT in proxy.
[<Rainer.Scherg rexroth.de>] PR#1326, #1573, #1942
*) Modify the log directives in httpd.conf-dist files to use CustomLog
so that users have examples of how CustomLog can be used.
[Lars Eilebrecht]
*) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
the Apache distribution tree. Until Apache 1.3 there was no real
out-of-the-box batch-capable build and installation procedure for the
complete Apache package. This is now provided by a top-level "configure"
script and a corresponding top-level "Makefile.tmpl" file. The goal is
to provide a GNU Autoconf-style frontend which is capable to both drive
the old src/Configure stuff in batch and additionally installs the
package with a GNU-conforming directory layout. Any options from the old
configuration scheme are available plus a lot of new options for flexibly
customizing Apache. [Ralf S. Engelschall]
*) The floating point ap_snprintf code wasn't threadsafe.
Had to remove the HAVE_CVT macro in order to do threadsafe
calling of the ?cvt() floating point routines. [Dean Gaudet]
*) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
*) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
[Jim Jagielski] PR#1901
*) BUG: Configure was using TCC and CC inconsistently. Make sure
Configure knows which CC we are using. [Jim Jagielski]
*) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
was defined in a parent directory. [Lars Eilebrecht]
*) API: ap_snprintf() code mutated into ap_vformatter(), which is
a generic printf-style routine that can call arbitrary output
routines. Use this to replace http_bprintf.c. Add new routines
psprintf(), pvsprintf() which allocate the exact amount of memory
required for a string from a pool. Use psprintf() to clean up
various bits of code which used ap_snprintf()/pstrdup().
[Dean Gaudet]
*) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
ap_snprintf() has different semantics and formatting codes than
snprintf(). [Dean Gaudet]
*) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
is necessary on at least Solaris where the /etc/rc?.d scripts
are run with these signals ignored, and "SIG_IGN" settings are
maintained across exec().
[Rein Tollevik <reint sys.sol.no>] PR#2009
*) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
used instead of lstat() and thus this flag didn't work as expected.
[Rein Tollevik <reint sys.sol.no>] PR#2010
*) Fix the proxy pass-through feature of mod_rewrite for the case of
existing QUERY_STRING now that mod_proxy was recently changed because of
the new URL parsing stuff. [Ralf S. Engelschall]
*) A few changes to scoreboard definitions which helps gcc generate
better code. [Dean Gaudet]
*) ANSI C doesn't guarantee that "int foo : 2" in a structure will
be a signed bitfield. So mark a few bitfields as signed to

was a problem and it wasn't taking effect. [Dean Gaudet]
*) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
[Dean Gaudet]
*) After a SIGHUP the listening sockets in the parent weren't
properly marked for closure on fork().
[Jürgen Keil <jk tools.de>] PR#2000
*) Allow %2F in two situations: 1) it is in the query part of the URI,
therefore not exposed to %2F -> '/' translations and 2) the request
is a proxy request, so we're not dealing with a local resource anyway.
Without this, the proxy would fail to work for any URL's with
%2f in them (occurs quite often in
http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
*) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
*) Make the shared object compilation command more portable by avoiding
the direct combination of `-c' & `-o' which is not honored by some
compilers like UnixWare's cc. [Ralf S. Engelschall]
*) WIN32: the proxy was creating filenames missing the last four
characters. While this normally doesn't stop anything from
working, it can result in extra collisions.
[Tim Costello <tjcostel socs.uts.edu.au>] PR#1890
*) Now mod_proxy uses the response string (in addition to the response status
code) from the already used FTP SIZE command to setup the Content-Length
header if available. [Ralf S. Engelschall] PR#1183
*) Reanimated the (still undocumented) proxy receive buffer size directive:
Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
name was really too generic, added documentation for this directive to
the mod_proxy.html and corrected the hyperlink to it in the
new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
*) Fix a bug in the src/helpers/fp2rp script and make it a little bit
faster [Martin Kraemer]
*) Make Configure die when you give it an unknown command switch.
[Ben Hyde]
*) Add five new and fresh manpages for the support programs: dbmmanage.1,
suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
and per default compiled support programs have manual pages - just to
document our stuff a little bit more and to be able to do really
Unix-like installations ;-) [Ralf S. Engelschall]
*) Major cleanups to the Configure script to make it and its generated
Makefiles again readable and maintainable: add SRCDIR option, removed
INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
generated sections, consequently added Makefile headers with inheritance
information, added subdir movement messages for easier following where
the build process currently stays (more verbose then standard Make, less
verbose than GNU make), same style to comments in the Configure script,
added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
*) Add the new ApacheBench program "ab" to src/support/: This is derived
from the ZeusBench benchmarking program and can be used to determine the
response performance of an Apache installation. This version is
officially licensed with Zeus Technology, Ltd. See the license agreement
statements in <199803171224.NAA24547 en1.engelschall.com> in apache-core.
[Ralf S. Engelschall]
*) API: Various core functions that are definately not part of the API
have been made static, and a few have been marked API_EXPORT. Still
more have been marked CORE_EXPORT and are not intended for general
use by modules. [Doug MacEachern, Dean Gaudet]
*) mod_proxy was not clearing the Proxy-Connection header from
requests; now it does. This did not violate any spec, however
causes poor interactions when you are talking to remote proxies.
[Marc Slemko] PR#1741
*) Various cleanups to the command line interface and manual pages.
[Ralf S. Engelschall]
*) cfg_getline() was not properly handling lines that did not end
with a line termination character. [Marc Slemko] PR#1869, 1909
*) Performance tweak to mod_log_config. [Dmitry Khrustalev]
*) Clean up some undocumented behavior of mod_setenvif related to
"merging" two SetEnvIf directives when they match the same header
and regex. Document that mod_setenvif will perform comparisons in
the order they appear in the config file. Optimize mod_setenvif by
doing more work at config time rather than at runtime.
[Dean Gaudet]
*) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
to allow for modules to overrule them and to reduce redefinition
warnings [Jim Jagielski]
*) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
[Jim Jagielski]
*) Making the hard-coded cross-module function call mime_find_ct() (from
mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
checking is really called even for proxy requests except for URLs with
HTTP schemes (because there we can optimize by not running the type
checking hooks due to the fact that the proxy gets the MIME Content-type
from the remote host later). This change cleans up mod_mime by removing
the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
especially unbundles mod_proxy and mod_mime. This way they both now can
be compiled as shared objects and are no longer tied together.
[Ralf S. Engelschall]
*) util.c cleanup and speedup. [Dean Gaudet]
*) API: Clarification, pstrndup() will always copy n bytes of the source
and NUL terminate at the (n+1)st byte. [Dean Gaudet]
*) Mark module command_rec and handler_rec structures const so that they
end up in the read-only data section (and are friendlier to systems
that don't do optimistic memory allocation on fork()). [Dean Gaudet]
*) Add check to the "Port" directive to make sure the specified
port is in the appropriate range. [Ben Hyde]
*) Performance improvements to invoke_handler().
[Dmitry Khrustalev <dima bog.msu.su>]
*) Added support for building shared objects even for library-style modules
(which are built from more than one object file). This now provides the
ability to build mod_proxy as a shared object module. Additionally
modules like mod_example are now also supported for shared object
building because the generated Makefiles now no longer assume there is at
least one statically linked module. [Ralf S. Engelschall]
*) API: Clarify usage of content_type, handler, content_encoding,
content_language and content_languages fields in request_rec. They
must always be lowercased; and the strings pointed to shouldn't
be modified (you must copy them to modify them). Fix a few bugs
related to this. [Dean Gaudet]
*) API: Clarification: except for RAW_ARGS, all command handlers can
treat the char * parameters as permanent, and modifiable. There
is no need to pstrdup() them. Clean up some needless pstrdup().
[Dean Gaudet]
*) Now mod_so keeps track of which module shared objects with which names
are loaded and thus avoids multiple loading and unloading and irritating
error_log messages. [Ralf S. Engelschall]
*) Prior to the existence of mod_setenv it was necessary to tweak the TZ
environment variable in the apache core. But that tweaking interferes
with mod_setenv. So don't tweak if the user has specified an explicit
TZ variable. [Jay Soffian <jay cimedia.com>] PR#1888
*) rputs() did not calculate r->sent_bodyct properly.
[Siegmund Stirnweiss <siegst kat.ina.de>] PR#1900
*) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
name, or left unset if this value is unavailable. Apache was setting
it to the IP address when unavailable.
[Tony Finch <fanf demon.net>] PR#1925
*) Various improvements to the configuration and build support for compiling
modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
OSF1 support with GCC and vendor compilers was added. This way shared
object support is now provided out-of-the-box for FreeBSD, Linux,
Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
[Ralf S. Engelschall]
*) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
and USE_OS2_SCOREBOARD. [Dean Gaudet]
*) Fix one more special locking problem for RewriteMap programs in
mod_rewrite: According to the documentation of flock(), "Locks are on
files, not file descriptors. That is, file descriptors duplicated
through dup(2) or fork(2) do not result in multiple instances of a lock,
but rather multiple references to a single lock. If a process holding a
lock on a file forks and the child explicitly unlocks the file, the
parent will lose its lock.". To overcome this we have to make sure the
RewriteLock file is opened _AFTER_ the childs were spawned which is now
the case by opening it in the child_init instead of the module_init API
hook. [Ralf S. Engelschall] PR#1029
*) Change to Location and LocationMatch semantics. LocationMatch no
longer lets a single slash match multiple adjacent slashes in the
URL. This change is for consistency with RewriteRule and
AliasMatch. Multiple slashes have meaning in URLs that they do
not have in (some) filesystems. Location on the other hand can
be considered a shorthand for a more complicated regex, and it
does match multiple slashes with a single slash -- which is
also consistent with the Alias directive.
[Dean Gaudet] related PR#1440
*) Fix bug with mod_mime_magic causing certain files, including files
of length 0, to result in no response from the server.
[Dean Gaudet]
*) The Configure script now generates src/include/ap_config.h which
contains the set of defines used when Apache is compiled on a platform.
This file can then be included by external modules before including
any Apache header files in case they are being built separately from
Apache. Along with this change, a couple of minor changes were
made to make Apache's #defines coexist peacefully with any autoconf
defines an external module might have. [Rasmus Lerdorf]
*) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
but without any RewriteXXXXX directives. Here mod_rewrite is given no
chance by the API to initialize its per-server configuration and thus
receives the wrong one from the main server. This is now avoided by
remembering the server together with the config structure while
configuring and later assuming there is no config when we see a
difference between the remembered server and the one calling us.
[Ralf S. Engelschall] PR#1790
*) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
is automatically disabled under configure time when the dbm_xxx functions
are not available. Second, two heavy source code errors in the DBM
support code were fixed. This makes DBM RewriteMap's usable again after
a long time of brokenness. [Ralf S. Engelschall] PR#1696
*) Now all configuration files support Unix-style line-continuation via
the trailing backslash ("\") character. This enables us to write down
complex or just very long directives in a more readable way. The
backslash character has to be really the last character before the
newline and it has not been prefixed by another (escaping) backslash.
[Ralf S. Engelschall]
*) When using ProxyPass the ?querystring was not passed correctly.
[Joel Truher <truher wired.com>]
*) To deal with modules being compiled and [dynamically] linked

[Ken Coar] PR#1448
*) WIN32: Preserve trailing slash in canonical path (and hence
in PATH_INFO). [Paul Sutton, Ben Laurie]
*) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
depending on the rev of Solaris and what mixture of modules
are in use. So it has been disabled, and Solaris is back to
using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
up static content only servers. Or it may fail unpredictably.
[Dean Gaudet] PR#1779, 1854, 1904
*) mod_test_util_uri.c created which tests the logic in util_uri.c.
[Dean Gaudet]
*) API: Rewrite of absoluteURI handling, and in particular how
absoluteURIs match vhosts. Unless a request is a proxy request, a
"http://host" url is treated as if a similar "Host:" header had been
supplied. This change was made to support future HTTP/1.x protocols
which may require clients to send absoluteURIs for all requests.
In order to achieve this change subtle changes were made to the API. In a
request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
that the unmodified uri can be retrieved easily. r->proxyreq is not set
by the core, modules must set it during the post_read_request or
translate_names phase.
Plus changes to the virtualhost test suite for absoluteURI testing.
This fixes several bugs with the proxy proxying requests to vhosts
managed by the same httpd.
[Dean Gaudet]
*) API: Cleanup of code in http_vhost.c, and remove vhost matching
code from mod_rewrite. The vhost matching is now performed by a
globally available function matches_request_vhost(). [Dean Gaudet]
*) Reduce memory usage, and speed up ServerAlias support. As a
side-effect users can list multiple ServerAlias directives
and they're all considered.

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

functionality needed for balancing between backend-servers when using
Apache as a Reverse Proxy. The looked up value here is a list of
servers). Second, `int' with the built-in maps named `tolower' and
`toupper' which can be used to map URL parts to a fixed case (this is an
essential feature to fix the case of server names when doing mass
virtual-hosting with the help of mod_rewrite instead of using
<VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
Jay Soffian <jay cimedia.com>] PR#1631
*) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
This directive lets Apache adjust the URL in Location-headers on HTTP
redirect responses sent by the remote server. This way the virtually
mapped area is no longer left on redirects and thus by-passed which is
especially essential when running Apache as a reverse proxy.

*) All BrowserMatch directives mentioned in
htdocs/manual/known_client_problems.html are in the default
configuration files. [Lars Eilebrecht]
*) MiNT port update. [Jan Paul Schmidt]
*) HTTP/1.1 requires x-gzip and gzip encodings be treated
equivalent, similarly for x-compress and compress. Apache
now ignores a leading x- when comparing encodings. It also
preserves the encoding the client requests (for example if
it requests x-gzip, then Apache will respond with x-gzip
in the Content-Encoding header).
[Ronald Tschalaer <Ronald.Tschalaer psi.ch>] PR#1772
*) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
*) Added mod_so module to support dynamic loading of modules on Unix

*) There are many cases where users do not want Apache to form
self-referential urls using the "canonical" ServerName and Port.
The new UseCanonicalName directive (default on), if set to off
will cause Apache to use the client-supplied hostname and port.
API: Part of this change required a change to the construct_url()
prototype; and the addition of get_server_name() and
get_server_port().
[Michael Douglass <mikedoug texas.net>, Dean Gaudet]
PR#315, 459, 485, 1433
*) Yet another rearrangement of the source tree.. now all the common
header files are in the src/include directory. The -Imain -Iap
references in Makefiles have been changed to the simpler -Iinclude
instead. In addition to simplifying the build a little bit, this
also makes it clear when a module is referencing something in a
other than kosher manner (e.g., the proxy including mod_mime.h).
Module-private header files (the proxy, mod_mime, the regex library,
and mod_rewrite) have not been moved to src/include; nor have
the OS-abstraction files. [Ken Coar]
*) Fix a bug where r->hostname didn't have the :port stripped
from it. [Dean Gaudet]
*) Tweaked the headers_out table size, and the subprocess_env
table size guess in rename_original_environment(). Added
MAKE_TABLE_PROFILE which can help discover make_table()
calls that use too small an initial guess, see alloc.c.
[Dean Gaudet]
*) Options and AllowOverride weren't properly merging in the main
server setting inside vhosts (only an issue when you have no
<Directory> or other section containing an Options that affects
a request). Options +foo or -foo in the main_server wouldn't
affect the main_server's lookup defaults. [Dean Gaudet]
*) Variable 'cwd' was being used pointlessly before being set.
[Ken Coar] PR#1738
*) r->allowed handling cleaned up in the standard modules.
[Dean Gaudet]
*) Some case-sensitivity issues cleaned up to be consistent with
RFC2068. [Dean Gaudet]
*) SIGURG doesn't exist everywhere.
[Mark Andrew Heinrich <heinrich tinderbox.Stanford.EDU>]
*) mod_unique_id was erroneously generating a second unique id when
an internal redirect occured. Such redirects occur, for example,
when processing a DirectoryIndex match. [Dean Gaudet]
*) API: table_add, table_merge, and table_set include implicit pstrdup()
of the key and value. But in many cases this is not required
because the key/value is a constant, or the value has been built
by pstrcat() or other similar means. New routines table_addn,
table_mergen, and table_setn have been added to the API, these
routines do not pstrdup() their arguments. The core code and
standard modules were changed to take advantage of these routines.
The resulting server is up to 20% faster in some situations.
Note that it is easy to get code subtly wrong if you pass a key/value
which is in a pool other than the pool of the table. The only
safe thing to do is to pass key/values which are in the pool of
the table, or in one of the ancestors of the pool of the table.
i.e. if the table is part of a subrequest, a value from the main
request's pool is OK since the subrequest pool is a sub_pool of the
main request's pool (and therefore has a lifespan at most as long as
the main pool). There is debugging code which can detect improper
usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
[Dmitry Khrustalev <dima bog.msu.su>, Dean Gaudet]
*) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
which don't exist on disk more gracefully; handles vhosts properly.
Update documentation to reflect the code -- if there's no
MimeMagicFile directive then the module is not enabled.
[Dean Gaudet]
*) PORT: Some older *nix dialects cannot automatically start scripts
which begin with a #! interpreter line (the shell starts the scripts
appropriately on these platforms). Apache now supports starting of
"hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
[Martin Kraemer, with code from Peter Wemm <peter zeus.dialix.oz.au>
taken from tcsh]
*) API: "typedef array_header table" removed from alloc.h, folks should
have been writing to use table as if it were an opaque type, but even
some standard modules got this wrong. By changing the definition
to "typedef struct table table" module authors will receive compile
time warnings that they're doing the wrong thing. This change
facilitates future changes with more sophisticated table
structures. Specifically, module authors should be using table_elts()
to get access to an array_header * for the table. [Dean Gaudet]
*) API: Renamed new_connection() to avoid namespace collision with LDAP
library routines. [Ken Coar, Rasmus Lerdorf]
*) WIN32: mod_speling is now available on the Win32 platform.
[Marc Slemko]
*) For clarity the following compile time definition was changed:
SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
and not be a general notice that the OS has mmap(). Now the
HAVE_MMAP/SHMGET #defines strictly are informational that the
OS has that method of shared memory; the type to use for
the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
and USE_SHMGET_SCOREBOARD). This allows outside modules to
determine if shared memory is available and allows Apache
to determine the best method to use for the scoreboard.
[Jim Jagielski]
*) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
as do various earlier versions. It should be safe on all versions.
Unixware 1.x appears to have the same SIGHUP bug as solaris does with

Otherwise we can't continue with a keepalive session. This shows up
as a POST problem with MSIE 4.0, typically against pages which are

*) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
The choice of flock vs. fcntl was made based on timings which showed that
even on non-NFS, non-exported filesystems fcntl() was an order of
magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
that single socket users will see no difference. [Dean Gaudet] PR#467

errno. [Marc Slemko]
*) Improve the warning message generated when a client drops the

multiple paths (e.g., in .c files as well as other .h files).
[Ken Coar]
*) The libap routines now have a header file for their prototypes,
src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]

*) For maximum portability, the environment passed to CGIs should
only contain variables whose names match the regex
/[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping

compatible for all the standard headers; and affects variables
set with SetEnv/BrowserMatch and similar directives.

[Ben Reser <breser regnow.com>] PR#1366
*) The bputc() macro was not properly integrated with the chunking

bogus chunked output. (Typically this will show up as problems
with Internet Explorer 4.0 reading a page, but other browsers
having no problem.) [Dean Gaudet]
*) Create LARGE_WRITE_THRESHOLD define which determines how many
bytes have to be supplied to bwrite() before it will consider
doing a writev() to assemble multiple buffers in one system
call. This is critical for modules such as mod_include,
mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
strings in some cases. The result would be extra effort
setting up writev(), and in many cases extra effort building
chunks. The default is 31, it can be overriden at compile
time. [Dean Gaudet]

A new pool was created which is passed to the module child_init

Now the rewriting engine (the heart of mod_rewrite) is organized more
straight-forward, first time well documented and reduced to the really
essential parts. All redundant cases were stripped off and processing now
is the same for both per-server and per-directory context with only a
minimum difference (the prefix stripping in per-dir context). As a
side-effect some subtle restrictions and two recently discovered problems
are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
context and restrictions on the substitution URL on redirects.
Additionally some minor source cleanups were done.

Changes with Apache 1.3b2 (there is no 1.3b1)
*) TestCompile was not passing $LIBS [Dean Gaudet]
*) Makefile.tmpl was not using $CFLAGS in the link phase.
[Martin Kraemer]
*) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
rudimentary memory debugger which can be used on live servers with
low impact -- it sets all allocated and freed memory bytes to 0xa5.
Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
and free() for each object. This is far more expensive and should
only be used for testing with tools such as Electric Fence and
Purify. See main/alloc.c for more details. [Dean Gaudet]
*) Configure uses a sh trap and didn't set its exitcode properly.
[Dean Gaudet] PR#1159
*) Yet another vhost revamp. Add the NameVirtualHost directive which
explicitly lists the ip:port pairs that are to be used for name-vhosts.
From a given ip:port, regardless what the Host: header is, you can
only reach the vhosts defined on that ip:port. The precedence of
vhosts was reversed to match other precedences in the config --
the earlier vhosts override the later vhosts. All vhost matching was
moved into http_vhost.[ch]. [Dean Gaudet]
*) ap_inline can be used to force inlining. GNUC __attribute__() can
be used for whatever reason is appropriate (i.e. format() warnings
for printf style functions). Both are enabled only with
gcc >= 2.7.x (so that we have fewer support issues with older
versions). [Dean Gaudet]
*) Fix support for Proxy Authentication (we were testing the response
status too early). [Marc Slemko]
*) CoreDumpDirectory directive directs where the core file is
written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
received. [Marc Slemko, Dean Gaudet]
*) PORT: Support for Atari MINT.
[Jan Paul Schmidt <Jan.P.Schmidt mni.fh-giessen.de>]
*) When booting, apache will now detach itself from stdin, stdout,
and stderr. stderr will not be detached until after the config
files have been read so you will be able to see initial error
messages. After that all errors are logged in the error_log.
This makes it more convenient to start apache via rsh, ssh,
or crontabs. [Dean Gaudet] PR#523
*) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
Also removed the auto-generated link to www.apache.org that was the
source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
*) send_fb would not detect aborted connections in some situations.

*) mod_imap should only handle GET methods. [Jay Bloodworth]
*) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
*) mod_autoindex improperly counted &escapes; as more than one
character in the description. It also improperly truncated
descriptions that were exactly the maximum length.
[Martin Kraemer]
*) RedirectMatch was not properly escaping the result (PR#1155). Also
"RedirectMatch /advertiser/(.*) $1" is now permitted.
[Dean Gaudet]
*) mod_include now uses symbolic names to check for request success
and return HTTP errors, and correctly handles all types of
redirections (previously it only did temporary redirect correctly).
[Ken Coar, Roy Fielding]
*) mod_userdir was modifying r->finfo in cases where it wasn't setting
r->filename. Since those two are meant to be in sync with each other
this is a bug. ["Paul B. Henson" <henson intranet.csupomona.edu>]
*) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
["Kaufman, Steven E" <Steven.Kaufman unisys.com>]
*) Inetd mode (which is buggy) uses timeouts without having setup the
jmpbuffer. [Dean Gaudet] PR#1064
*) Work around problem under Linux where a child will start looping

[Rick Franchuk <rickf transpect.net>] PR#1107, 987, 588
*) Fixed error in proxy_util.c when looping through multiple host IP
addresses. [Lars Eilebrecht] PR#974
*) If BUFFERED_LOGS is defined then mod_log_config will do atomic
buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
bytes before writing, but it will never split a log entry across a
buffer boundary. [Dean Gaudet]
*) API: the short_score record has been split into two pieces, one which
the parent writes on, and one which the child writes on. As part of
this change the get_scoreboard_info() function was removed, and
scoreboard_image was exported. This change fixes a race condition
in file based scoreboard systems, and speeds up changes involving the
scoreboard in earlier 1.3 development. [Dean Gaudet]
*) API: New register_other_child() API (see http_main.h) which allows
modules to register children with the parent for maintenance. It
is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
*) API: New piped_log API (see http_log.h) which implements piped logs,
and will use register_other_child to implement reliable piped logs
when it is available. The reliable piped logs part can be disabled
by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
logs is only available on Unix. [Dean Gaudet]
*) API: set_last_modified() broken into set_last_modified(), set_etag(), and
meets_conditions(). This allows conditional HTTP selection to be
handled separately from the storing of the header fields, and provides
the ability for CGIs to set their own ETags for conditional checking.
[Ken Coar, Roy Fielding] PR#895
*) Changes to mod_log_config to allow naming of format strings.
Format nicknames are defined with "LogFormat fmt nickname", and can
be used with "LogFormat nickname" and "CustomLog logtarget nickname".
[Ken Coar]
*) New module, "mod_speling", which can help find files even when
the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
*) API: New function child_terminate() triggers the child process to
exit, while allowing the child finish what it needs to for the
current request first.
[Doug MacEachern, Alexei Kosut]
*) Windows now defaults to using full status reports with mod_status.
[Alexei Kosut] PR #1094
*) *Really* disable all mod_rewrite operations if the engine is off.
Some things (like RewriteMaps) were checked/performed even if they
weren't supposed to be. [Ken Coar] PR #991
*) Implement a new timer scheme which eliminates the need to call alarm() all
the time. Instead a counter in the scoreboard for each child is used to
show when the child has made forward progress. The parent samples this
counter every scoreboard maintenance cycle, and issues SIGALRM if no
progress has been made in the timeout period. This reduces the static
request best-case syscall count to 22 from 29. This scheme is only
used by systems with memory-based scoreboards. [Dean Gaudet]
*) The proxy now properly handles CONNECT requests which are sent
to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
*) A script called apachectl has been added to the support
directory. This script allows you to do things such as
"apachectl start" and "apachectl restart" from the command
line. [Marc Slemko]
*) Modules and core routines are now put into libraries, which
simplifies the link line tremendously (among other advantages).
[Paul Sutton]
*) Some of the MD5 names defined in Apache have been renamed to have
an `ap_' prefix to avoid conflicts with routines supplied by
external libraries. [Ken Coar]
*) Removal of mod_auth_msql.c from the distribution. There are many
other options for databases today. Rather than offer one option,
offer none at this time. mod_auth_msql and other SQL database
authentication modules can be found at the Apache Module Registry.
http://modules.apache.org/ It would be nice to offer a generic
mod_auth_sql option in the near future.
*) PORT: BeOS support added [Alexei Kosut]
*) Configure no longer accepts the -make option, since it creates
Makefile on the fly based on Makefile.tmpl and Configuration.
*) Apache now gracefully shuts down when it receives a SIGTERM, instead
of forcibly killing off all its processes and exiting without
cleaning up. [Alexei Kosut]
*) API: A new field in the request_rec, r->mtime, has been added to
avoid gratuitous parsing of date strings. It is intended to hold
the last-modified date of the resource (if applicable). An
update_mtime() routine has also been added to advance it if
appropriate. [Roy Fielding, Ken Coar]
*) SECURITY: If a htaccess file can not be read due to bad permissions,
deny access to the directory with a HTTP_FORBIDDEN. The previous
behavior was to ignore the htaccess file if it could not be read.
This change may make some setups with unreadable htaccess files
stop working. [Marc Slemko] PR#817
*) Add aplog_error() providing a mechanism to define levels of
verbosity to the server error logging. This addition also provides
the ability to log errors using syslogd. Error logging is configurable
on a per-server basis using the LogLevel directive. Conversion
of log_*() in progress. [Randy Terbush]
*) Further enhance aplog_error() to not log filename, line number, and
errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
*) WIN32: Canonicalise filenames under Win32. Short filenames are
converted to long ones. Backslashes are converted to forward
slashes. Case is converted to lower. Parts of URLs that do not
correspond to files are left completely alone. [Ben Laurie]
*) PORT: 2 new OSs added to the list of ports:
Encore's UMAX V: Arieh Markel <amarkel encore.com>
Acorn RISCiX: Stephen Borrill <sborrill xemplar.co.uk>
*) Add the server version (SERVER_VERSION macro) to the "server
configured and running" entry in the error_log. Also build an
object file at link-time that contains the current time
(SERVER_BUILT global const char[]), and include that in the
message. [Ken Coar]
*) Set r->headers_out when sending responses from the proxy.
This fixes things such as the logging of headers sent from
the proxy. [Marc Slemko] PR#659
*) support/httpd_monitor is no longer distributed because the
scoreboard should not be file based if at all possible. Use
mod_status to see current server snapshot.
*) (set_file_slot): New function, allowing auth directives to be
independent of the server root, so the server documents can be
moved to a different directory or machine more easily.
[David J. MacKenzie]
*) If no TransferLog is given explicitly, decline
to log. This supports coexistence with other logging modules,
such as the custom one that UUNET uses. [David J. MacKenzie]
*) Check for titles in server-parsed HTML files.
Ignore leading newlines and returns in titles. The old behavior
of replacing a newline after <title> with a space causes the
title to be misaligned in the listing. [David J. MacKenzie]
*) Change mod_cern_meta to be configurable on a per-directory basis.
[David J. MacKenzie]
*) Add 'Include' directive to allow inclusion of configuration
files within configuration files. [Randy Terbush]
*) Proxy errors on connect() are logged to the error_log (nothing
new); now they include the IP address and port that failed
(*that's* new). [Ken Coar, Marc Slemko] PR#352
*) Various architectures now define USE_MMAP_FILES which causes
the server to use mmap() for static files. There are two
compile-time tunables MMAP_THRESHOLD (minimum number of bytes
required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
number of bytes written in one cycle from a single mmap()d object,
default 32768). [Dean Gaudet]
*) API: Added post_read_request API phase which is run right after reading
the request from a client, or right after an internal redirect. It is
useful for modules setting environment variables that depend only on
the headers/contents of the request. It does not run during subrequests
because subrequests inherit pretty much everything from the main
request. [Dean Gaudet]
*) Added mod_unique_id which is used to generate a unique identifier for
each hit, available in the environment variable UNIQUE_ID.
[Dean Gaudet]
*) init_modules is now called after the error logs have been opened. This
allows modules to emit information messages into the error logs.
[Dean Gaudet]
*) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
information for case where proxy module is not available. [Marc Slemko]
*) PORT: Apache has need for mutexes to serialize its children around
accept. In prior versions either fcntl file locking or flock file
locking were used. The method is chosen by the definition of
USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
and FLOCK for flock(). New options have been added:
- SYSVSEM to use System V style semaphores
- PTHREAD to use POSIX threads (appears to work on Solaris only)
- USLOCK to use IRIX uslock
Based on timing various techniques, the following changes were made
to the defaults:
- Linux 2.x uses flock instead of fcntl
- Solaris 2.x uses pthreads
- IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
[Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec vtcom.fr>,
Martijn Koster <m.koster pobox.com>]
*) PORT: The semantics of accept/select make it very desirable to use
mutexes to serialize accept when multiple Listens are in use. But
in the case where only a single socket is open it is sometimes
redundant to serialize accept(). Not all unixes do a good job with
potentially dozens of children blocked on accept() on the same
socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
the server will avoid serialization when listening on only one socket,
and use serialization when listening on multiple sockets.
[Dean Gaudet] PR#467
*) Configure changes: TestLib replaced by TestCompile, which has
some additional capability (such as doing a sanity check of
the compiler and flags selected); the version of Solaris is now
available via the #define value of SOLARIS2; IRIX n32bit libs
now supported and selectable by new Configuration Rule: IRIXN32;
We no longer default to -O2 optimization. [Jim Jagielski]
*) Updated Configure: Configuration now uses AddModule to specify
module source or binary file location, relative to src directory.
Modules can be dropped into modules/extra, or in their own
directory, and modules can come with a Makefile or Configure can
create one. Modules can add compiler or library information to
generated Makefiles. [Paul Sutton]
*) Source core re-organisation: distributed modules are now in
modules/standard. All other source code is in main. OS-specific
code is in os/{unix,emx,win32} directories. [Paul Sutton]
*) mod_browser has been removed, since it's replaced by mod_setenvif.
[Ken Coar]
*) Fix another long-standing bug in sub_req_lookup_file where it would
happily skip past access checks on subdirectories looked up with
relative paths. (It's used by mod_dir, mod_negotiation,
and mod_include.) [Dean Gaudet]
*) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
N is the number of <Directory> sections, and M is the number of
components in the filename of an object.
To achieve this optimization the following config changes were made:
- Wildcards (* and ?, not the regex forms) in <Directory>s,
<Files>s, and <Location>s now treat a slash as a special
character. For example "/home/*/public_html" previously would
match "/home/a/andrew/public_html", now it only matches things
like "/home/bob/public_html". This mimics /bin/sh behaviour.
- It's possible now to use [] wildcarding in <Directory>, <Files>
or <Location>.
- Regex <Directory>s are applied after all non-regex <Directory>s.
[Dean Gaudet]
*) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
and corrupted paths. [Dean Gaudet]
*) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
First the grouped parts of RewriteRule pattern matches (parenthesis!) can
be accessed now via backreferences $1..$9 in RewriteConds test-against
strings in addition to RewriteRules subst string. Second the grouped
parts of RewriteCond pattern matches (parenthesis!) can be accessed now
via backreferences %1..%9 both in following RewriteCond test-against
strings and RewriteRules subst string. This provides maximum flexibility
through the use of backreferences.
Additionally the rewriting engine was cleaned up by putting common
code to the new expand_backrefs_inbuffer() function.
[Ralf S. Engelschall]
*) When merging the main server's <Directory> and <Location> sections into
a vhost, put the main server's first and the vhost's second. Otherwise
the vhost can't override the main server. [Dean Gaudet] PR#717
*) The <Directory> code would merge and re-merge the same section after
a match was found, possibly causing problems with some modules.
[Dean Gaudet]
*) ip-based vhosts are stored and queried using a hashing function, which
has been shown to improve performance on servers with many ip-vhosts.
Some other changes had to be made to accommodate this:
- the * address for vhosts now behaves like _default_
- the matching process now is:
- match an ip-vhost directly via hash (possibly matches main
server)
- if that fails, just pretend it matched the main server
- if so far only the main server has been matched, perform
name-based lookups (ServerName, ServerAlias, ServerPath)
*only on name-based vhosts*
- if they fail, look for _default_ vhosts
[Dean Gaudet, Dave Hankins <dhankins sugarat.net>]
*) dbmmanage overhaul:
- merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
- tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
- provide better seed for rand
- prompt for password as per getpass(3) (turn off echo, read from
/dev/tty, etc.)
- use "newstyle" crypt based on $Config{osname} ($^O)
- will not add a user if already in database, use new `update' command
instead
- added `check' command to check a users' password
- added `import' command to convert existing password text-files or
dbm files exported with `view'
- more descriptive usage, general cleanup, 'use strict' clean, etc.
[Doug MacEachern]
*) Added psocket() which is a pool form of socket(), various places within
the proxy weren't properly blocking alarms while registering the cleanup
for its sockets. bclose() now uses pclose() and pclosesocket(). There
was a bug where the client socket was being close()d twice due a still
registered cleanup. [Dean Gaudet]
*) A few cleanups were made to reduce time(), getpid(), and signal() calls.
[Dean Gaudet]
*) PORT: AIX >= 4.2 requires -lm due to libc changes.
[Jason Venner <jason idiom.com>] PR#667
*) Enable ``=""'' for RewriteCond directives to match against
the empty string. This is the preferred way instead of ``^$''.
[Ralf S. Engelschall]
*) Fixed an infinite loop in mod_imap for references above the server root
[Dean Gaudet] PR#748
*) mod_proxy now has a ReceiveBufferSize directive, similar to
SendBufferSize, so that the TCP window can be set appropriately
for LFNs. [Phillip A. Prindeville]
*) mod_browser has been replaced by the more general mod_setenvif
(courtesy of Paul Sutton). BrowserMatch* directives are still
available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
UnSetEnvIfZero directives. [Ken Coar]
*) "HostnameLookups double" forces double-reverse DNS to succeed in
order for remote_host to be set (for logging, or for the env var
REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
[Dean Gaudet]
*) mod_access overhaul:
- Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
and cidr syntax (i.e. 10.1.0.0/16). PR#762
- Critical path was sped up by pre-computing a few things at config
time.
- The undocumented syntax "allow user-agents" was removed,
the replacement is "allow from env=foobar" combined with mod_browser.
- When used with hostnames it now forces a double-reverse lookup
no matter what the directory settings are. This double-reverse
doesn't affect any of the other routines that use the remote
hostname. In particular it's still passed to CGIs and the log
without the double-reverse check. Related PR#860.
[Dean Gaudet]
*) When a large bwrite() occurs (larger than the internal buffer size),
while there is already something in the buffer, apache will combine
the large write and the buffer into a single writev(). (This is
in anticipation of using mmap() for reading files.)
[Dean Gaudet]
*) In obscure cases where a partial socket write occurred while chunking,
Apache would omit the chunk header/footer on the next block. Cleaned
up other bugs/inconsistencies in error conditions in buff.c. Fixed
a bug where a long pause in DNS lookups could cause the last packet
of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
*) API: Added child_exit function to module structure. This is called
once per "heavy-weight process" just before a server child exit()'s
e.g. when max_requests_per_child is reached, etc.
[Doug MacEachern, Dean Gaudet]
*) mod_include cleanup showed that handle_else was being used to handle
endif. It didn't cause problems, but it was cleaned up too.
[Howard Fear]
*) mod_cern_meta would attempt to find meta files for the directory itself
in some cases, but not in others. It now avoids it in all cases.
[Dean Gaudet]
*) mod_mime_magic would core dump if there was a decompression error.
[Martin Kraemer <Martin.Kraemer mch.sni.de>] PR#904
*) PORT: some variants of DGUX require -lsocket -lnsl
[Alexander L Jones <alex systems-options.co.uk>] PR#732
*) mod_autoindex now allows sorting of FancyIndexed directory listings
by the various fields (name, size, et cetera), either in ascending
or descending order. Just click on the column header. [Ken Coar]
*) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
CPUs like the Alpha. Apache still stores ints in pointers, but that's
the relatively safe direction. [Dean Gaudet] PR#344
*) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
[Igor N Kovalenko <infoh mail.wplus.net>] PR#683
*) child_main avoids an unneeded call to select() when there is only one
listening socket. [Dean Gaudet]
*) In the event that the server is starved for idle servers it will
spawn 1, then 2, then 4, ..., then 32 servers each second,
doubling each second. It'll also give a warning in the errorlog
since the most common reason for this is a poor StartServers
setting. The define MAX_SPAWN_RATE can be used to raise/lower
the maximum. [Dean Gaudet]
*) Apache now provides an effectively unbuffered connection for
CGI scripts. This means that data will be sent to the client
as soon as the CGI pauses or stops output; previously, Apache would
buffer the output up to a fixed buffer size before sending, which
could result in the user viewing an empty page until the CGI finished
or output a complete buffer. It is no longer necessary to use an
"nph-" CGI to get unbuffered output. Given that most CGIs are written
in a language that by default does buffering (e.g. perl) this
shouldn't have a detrimental effect on performance.
"nph-" CGIs, which formerly provided a direct socket to the client
without any server post-processing, were not fully compatible with
HTTP/1.1 or SSL support. As such they would have had to implement
the transport details, such as encryption or chunking, in order
to work properly in certain situations. Now, the only difference
between nph and non-nph scripts is "non-parsed headers".
[Dean Gaudet, Sameer Parekh, Roy Fielding]
*) If a BUFF is switched from buffered to unbuffered reading the first
bread() will return whatever remained in the buffer prior to the
switch. [Dean Gaudet]
Changes with Apache 1.3a1
*) Added another Configure helper script: TestLib. It determines
if a specified library exists. [Jim Jagielski]
*) PORT: Allow for use of n32bit libraries under IRIX 6.x
[derived from patch from Jeff Hayes <jhayes aw.sgi.com>]
PR#721
*) PORT: Some architectures use size_t for various lengths in network
functions such as accept(), and getsockname(). The definition
NET_SIZE_T is used to control this. [Dean Gaudet]
*) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
*) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
[Igor N Kovalenko <infoh mail.wplus.net>]
*) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
"downgrade-1.0" which causes Apache to pretend it received a 1.0.
[Dean Gaudet] related PR#875
*) API: Correct child_init() slot declaration from int to void, to
match the init() declaration. Update mod_example to use the new
hook. [Ken Coar]

[Doug MacEachern]
*) get_client_block() returns wrong length if policy is
REQUEST_CHUNKED_DECHUNK.

*) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
["Darren O'Shaughnessy" <darren aaii.oz.au>] PR#846
*) AddModuleInfo directive for mod_info which allows you to annotate
the output of mod_info. ["Lou D. Langholtz" <ldl usi.utah.edu>]
*) Added NoProxy directive to avoid using ProxyRemote for selected
addresses. Added ProxyDomain directive to cause unqualified
names to be qualified by redirection.
[Martin Kraemer <Martin.Kraemer mch.sni.de>]
*) Support Proxy Authentication, and don't pass the Proxy-Authorize
header to the remote host in the proxy. [Sameer Parekh and
Wallace]
*) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
URLs, fixed rewritelog(), fixed forced response code handling on
redirects from within .htaccess files, disabled pipe locking under
braindead SunOS 4.1.x, allow env variables to be set even on rules with
no substitution, bugfixed situations where HostnameLookups is off, made
mod_rewrite more thread-safe for NT port and fixed problem when creating
an empty query string via "xxx?".
This update also removes the copyright of Ralf S. Engelschall,
i.e. now mod_rewrite no longer has a shared copyright. Instead is is
exclusively copyrighted by the Apache Group now. This happened because
the author now has gifted mod_rewrite exclusively to the Apache Group and
no longer maintains an external version.
[Ralf S. Engelschall]
*) API: Added child_init function to module structure. This is called
once per "heavy-weight process" before any requests are handled.
See http_config.h for more details. [Dean Gaudet]
*) Anonymous_LogEmail was logging on each subrequest.
[Dean Gaudet] PR#421, 868
*) API: Added is_initial_req() which tests if the request being
processed is the initial request, or a subrequest.
[Doug MacEachern]
*) Extended SSI (mod_include) now handles additional relops for
string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
*) Configure fixed to correctly propagate user-selected options and
settings (such as CC and OPTIM) to Makefiles other than
src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
*) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
directory indices to start with the contents of the HeaderName file
if there is one. If there isn't one, the behaviour is unchanged.
[Ken Coar, Roy Fielding, Andrey A. Chernov]
*) WIN32: Modules can now be dynamically loaded DLLs using the
LoadModule/LoadFile directives. Note that module DLLs must be
compiled with the multithreaded DLL version of the runtime library.
[Alexei Kosut and Ben Laurie]
*) Automatic indexing removed from mod_dir and placed into mod_autoindex.
This allows the admin to completely remove automatic indexing
from the server, while still supporting the basic functions of
trailing-slash redirects and DirectoryIndex files. Note that if
you're carrying over an old Configuration file and you use directory
indexing then you'll want to add:
Module autoindex_module mod_autoindex.o
before mod_dir in your Configuration. [Dean Gaudet]
*) popendir/pclosedir created to properly protect directory scanning.
[Dean Gaudet] PR#525
*) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
[Alexei Kosut]
*) The AccessFileName directive can now take more than one filename.
["Lou D. Langholtz" <ldl usi.utah.edu>]
*) The new mod_mime_magic can be used to "magically" determine the type
of a file if the extension is unknown. Based on the unix file(1)
command. [Ian Kluft <ikluft cisco.com>]
*) We now determine and display the time spent processing a
request if desired. [Jim Jagielski]
*) mod_status: PID field of "dead" child slots no longer displays
main httpd process's PID. [Jim Jagielski]
*) Makefile.nt added - to build all the bits from the command line:
nmake -f Makefile.nt
Doesn't yet work properly. [Ben Laurie]
*) Default text of 404 error is now "Not Found" rather than the
potentially misleading "File Not Found". [Ken Coar]
*) CONFIG: "HostnameLookups" now defaults to off because it is far better
for the net if we require people that actually need this data to
enable it. [Linus Torvalds]
*) directory_walk() is an expensive function, keep a little more state to
avoid needless string counting. Add two new functions make_dirstr_parent
and make_dirstr_prefix which replace all existing uses of make_dirstr.
The new functions are a little less general than make_dirstr, but
work more efficiently (less memory, less string counting).
[Dean Gaudet]
*) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
to LDFLAGS) to avoid complications with lex rules in make files.
[Dean Gaudet] PR#372
*) run_method optimized to avoid needless scanning over NULLs in the
module list. [Dean Gaudet]
*) Revamp of (unix) scoreboard management code such that it avoids
unnecessary traversals of the scoreboard on each hit. This is
particularly important for high volume sites with a large
HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
httpd.h. [Dean Gaudet]
*) In configurations using multiple Listen statements it was possible for
busy sockets to starve other sockets of service. [Dean Gaudet]
*) Added hook so standalone_main can be replaced at compile time
(define STANDALONE_MAIN)
[Doug MacEachern]
*) Lowest-level read/write functions in buff.c will be replaced with
the SFIO library calls sfread/sfwrite if B_SFIO is defined at
compile time. The default sfio discipline will behave as apache
would without sfio compiled in.
[Doug MacEachern]
*) Enhance UserDir directive (mod_userdir) to accept a list of
usernames for the 'disable' keyword, and add 'enable user...' to
selectively *en*able userdirs if they're globally disabled.
[Ken Coar]
*) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
will work with Netscape dbm files. (dbmmanage will probably not
work however.) [Alexander Spohr <aspohr netmatic.com>] PR#444
*) Add a ListenBacklog directive to control the backlog parameter
passed to listen(). Also change the default to 511 from 512.
[Marc Slemko]
*) API: A new handler response DONE which informs apache that the
request has been handled and it can finish off quickly, similar to
how it handles errors. [Rob Hartill]
*) Turn off chunked encoding after sending terminating chunk/footer
so that we can't do it twice by accident. [Roy Fielding]
*) mod_expire also issues Cache-Control: max-age headers.
[Rob Hartill]
*) API: Added kill_only_once option for free_proc_chain so that it won't
aggressively try to kill off specific children. For fastcgi.
[Stanley Gambarin <gambarin OpenMarket.com>]
*) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
*) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
When used together, these cause mod_dir to emit HEIGHT and WIDTH
attributes in the FancyIndexing IMG tags. [Ken Coar]
*) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
*) PORT: Added Windows NT support
[Ben Laurie and Ambarish Malpani <ambarish valicert.com>]
Changes with Apache 1.2.6
*) mod_include when using XBitHack Full would send ETags in addition to
sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
[Dean Gaudet] PR#1133
*) SECURITY: When a client connects to a particular port/addr, and
gives a Host: header ensure that the virtual host requested can
actually be reached via that port/addr. [Ed Korthof <ed organic.com>]
*) Support virtual hosts with wildcard port and/or multiple ports
properly. [Ed Korthof <ed organic.com>]
*) Fixed some case-sensitivity issues according to RFC2068.
[Dean Gaudet]
*) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
and mod_include.c. [Dean Gaudet]
*) Variable 'cwd' was being used pointlessly before being set.
[Ken Coar] PR#1738
*) SIGURG doesn't exist on all platforms.
[Mark Andrew Heinrich <heinrich tinderbox.Stanford.EDU>]
*) When an error occurs during a POST, or other operation with a
request body, the body has to be read from the net before allowing
a keepalive session to continue. [Roy Fielding] PR#1399
*) When an error occurs in fcntl() locking suggest the user look up
the docs for LockFile. [Dean Gaudet]
*) table_set() and table_unset() did not deal correctly with
multiple occurrences of the same key. [Stephen Scheck
<sscheck infonex.net>, Ben Laurie] PR#1604
*) send_fd_length() did not calculate total_bytes_sent properly in error
cases. [Ben Reser <breser regnow.com>] PR#1366
*) r->connection->user was allocated in the wrong pool causing corruption
in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
*) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
Also removed the auto-generated link to www.apache.org that was the
source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
*) Multiple "close" tokens may have been set in the "Connection"
header, not an error, but a waste.
[<Ronald.Tschalaer psi.ch>] PR#1683
*) "basic" and "digest" auth tokens should be tested case-insensitive.
[<Ronald.Tschalaer psi.ch>] PR#1599, PR#1666
*) It appears the "257th byte" bug (see
htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
at the 256th byte as well. Fixed. [Dean Gaudet]
*) mod_rewrite would not handle %3f properly in some situations.
[Ralf Engelschall]
*) Apache could generate improperly chunked HTTP/1.1 responses when
the bputc() or rputc() functions were used by modules (such as
mod_include). [Dean Gaudet]
*) #ifdef wrap a few #defines in httpd.h to make life easier on
some ports. [Ralf Engelschall]
*) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
*) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
*) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
Changes with Apache 1.2.5
*) SECURITY: Fix a possible buffer overflow in logresolve. This is
only an issue on systems without a MAXDNAME define or where
the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
*) Fix an improper length in an ap_snprintf call in proxy_date_canon().
[Marc Slemko]
*) Fix core dump in the ftp proxy when reading incorrectly formatted
directory listings. [Marc Slemko]
*) SECURITY: Fix possible minor buffer overflow in the proxy cache.
[Marc Slemko]
*) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
is used to read various types of files such as htaccess and
htpasswd files. [Marc Slemko]
*) SECURITY: Ensure that the buffer returned by ht_time is always
properly null terminated. [Marc Slemko]
*) SECURITY: General mod_include cleanup, including fixing several
possible buffer overflows and a possible infinite loop. This cleanup
was done against 1.3 code and then backported to 1.2, the result
is a large difference (due to indentation cleanup in 1.3 code).
Users interested in seeing a smaller set of relevant differences
should consider comparing against src/modules/standard/mod_include.c
from the 1.3b3 release. Non-indentation changes to mod_include
between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
*) SECURITY: Numerous changes to mod_imap in a general cleanup
including fixing a possible buffer overflow. This cleanup also
was done with 1.3 code as a basis, see the the previous note
about mod_include. [Dean Gaudet]
*) SECURITY: If a htaccess file can not be read due to bad
permissions, deny access to the directory with a HTTP_FORBIDDEN.
The previous behavior was to ignore the htaccess file if it could not
be read. This change may make some setups with unreadable
htaccess files stop working. [Marc Slemko] PR#817
*) SECURITY: no2slash() was O(n^2) in the length of the input.
Make it O(n). This inefficiency could be used to mount a denial
of service attack against the Apache server. Thanks to
Michal Zalewski <lcamtuf boss.staszic.waw.pl> for reporting
this. [Dean Gaudet]
*) mod_include used uninitialized data for some uses of && and ||.
[Brian Slesinsky <bslesins wired.com>] PR#1139
*) mod_imap should decline all non-GET methods.
[Jay Bloodworth <jay pathways.sde.state.sc.us>]
*) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
*) mod_userdir was modifying r->finfo in cases where it wasn't setting
r->filename. Since those two are meant to be in sync with each other
this is a bug. ["Paul B. Henson" <henson intranet.csupomona.edu>]
*) mod_include did not properly handle all possible redirects from sub-
requests. [Ken Coar]
*) Inetd mode (which is buggy) uses timeouts without having setup the
jmpbuffer. [Dean Gaudet] PR#1064
*) Work around problem under Linux where a child will start looping
reporting a select error over and over.
[Rick Franchuk <rickf transpect.net>] PR#1107
Changes with Apache 1.2.4
*) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
always making requests with the full-URI instead of just the URI path.
[Marc Slemko, Roy Fielding]
*) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
on this platform. [Marc Slemko]
Changes with Apache 1.2.3
*) The request to a remote proxy was mangled if it was generated as the
result of a ProxyPass directive. URL schemes other than http:// were not
supported when ProxyRemote was used. [Lars Eilebrecht] PR#260, PR#656,
PR#699, PR#713, PR#812
*) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
information for case where proxy module is not available. [Marc Slemko]
*) Force proxy to always respond as HTTP/1.0, which it was failing to
do for errors and cached responses. [Roy Fielding]
*) PORT: Improved support for ConvexOS 11. [Jeff Venters]
Changes with Apache 1.2.2 [not released]
*) Fixed another long-standing bug in sub_req_lookup_file where it would
happily skip past access checks on subdirectories looked up with relative
paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
[Dean Gaudet]
*) Add lockfile name to error message printed out when
USE_FLOCK_SERIALIZED_ACCEPT is defined.
[Marc Slemko]
*) Enhanced the chunking and error handling inside the buffer functions.
[Dean Gaudet, Roy Fielding]
*) When merging the main server's <Directory> and <Location> sections into
a vhost, put the main server's first and the vhost's second. Otherwise
the vhost can't override the main server. [Dean Gaudet] PR#717
*) The <Directory> code would merge and re-merge the same section after
a match was found, possibly causing problems with some modules.
[Dean Gaudet]
*) Fixed an infinite loop in mod_imap for references above the server root.
[Dean Gaudet] PR#748
*) mod_include cleanup showed that handle_else was being used to handle
endif. It didn't cause problems, but it was cleaned up too.
[Howard Fear]
*) Last official synchronization of mod_rewrite with author version (because
mod_rewrite is now directly developed by the author at the Apache Group):
o added diff between mod_rewrite 3.0.6+ and 3.0.9
minus WIN32/NT stuff, but plus copyright removement.
In detail:
- workaround for detecting infinite rewriting loops
- fixed setting of env vars when "-" is used as subst string
- fixed forced response code on redirects (PR#777)
- fixed cases where r->args is ""
- kludge to disable locking on pipes under braindead SunOS
- fix for rewritelog in cases where remote hostname is unknown
- fixed totally damaged request_rec walk-back loop
o remove static from local data and add static to global ones.
o replaced ugly proxy finding stuff by simple
find_linked_module("mod_proxy") call.
o added missing negation char on rewritelog()
o fixed a few comment typos
[Ralf S. Engelschall]
*) Anonymous_LogEmail was logging on each subrequest.
[Dean Gaudet] PR#421, PR#868
*) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
"downgrade-1.0" which causes Apache to pretend it received a 1.0.
Additionally mod_browser now triggers during translate_name to workaround
a deficiency in the header_parse phase.
[Dean Gaudet] PR#875
*) get_client_block() returns wrong length if policy is
REQUEST_CHUNKED_DECHUNK.
[Kenichi Hori <ken d2.bs1.fc.nec.co.jp>] PR#815
*) Properly treat <files> container like other containers in mod_info.
[Marc Slemko] PR#848
*) The proxy didn't treat the "Host:" keyword of the host header as case-
insensitive. The proxy would corrupt the first line of a response from
an HTTP/0.9 server. [Kenichi Hori <ken d2.bs1.fc.nec.co.jp>] PR#813,814
*) mod_include would log some bogus values occasionally.
[Skip Montanaro <skip calendar.com>, Marc Slemko] PR#797
*) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
under Solaris 2.x (up through 2.5.1). It has been fixed.
[Dean Gaudet] PR#832
*) API: In HTTP/1.1, whether or not a request message contains a body
is independent of the request method and based solely on the presence
of a Content-Length or Transfer-Encoding. Therefore, our default
handlers need to be prepared to read a body even if they don't know
what to do with it; otherwise, the body would be mistaken for the
next request on a persistent connection. discard_request_body()
has been added to take care of that. [Roy Fielding] PR#378
*) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
release version number, such that it always increases along the
same lines as our source code branching. [Roy Fielding]
*) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
Changes with Apache 1.2.1
*) SECURITY: Don't serve file system objects unless they are plain files,
symlinks, or directories. This prevents local users from using pipes
or named sockets to invoke programs for an extremely crude form of
CGI. [Dean Gaudet]
*) SECURITY: HeaderName and ReadmeName were settable in .htaccess and
could contain "../" allowing a local user to "publish" any file on
the system. No slashes are allowed now. [Dean Gaudet]
*) SECURITY: It was possible to violate the symlink Options using mod_dir
(headers, readmes, titles), mod_negotiation (type maps), or
mod_cern_meta (meta files). [Dean Gaudet]
*) SECURITY: Apache will refuse to run as "User root" unless
BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
*) CONFIG: If a symlink pointed to a directory then it would be disallowed
if it contained a .htaccess disallowing symlinks. This is contrary
to the rule that symlink permissions are tested with the symlink
options of the parent directory. [Dean Gaudet] PR#353
*) CONFIG: The LockFile directive can be used to place the serializing
lockfile in any location. It previously defaulted to /usr/tmp/htlock.
[Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
Marc Slemko]
*) Request processing now retains state of whether or not the request
body has been read, so that internal redirects and subrequests will
not try to read it twice (and block). [Roy Fielding]
*) Add a placeholder in modules/Makefile to avoid errors with certain
makes. [Marc Slemko]
*) QUERY_STRING was unescaped in mod_include, it shouldn't be.
[Dean Gaudet] PR#644
*) mod_include was not properly changing the current directory.
[Marc Slemko] PR#742
*) Attempt to work around problems with third party libraries that do not
handle high numbered descriptors (examples include bind, and
solaris libc). On all systems apache attempts to keep all permanent
descriptors above 15 (called the low slack line). Solaris users
can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
which keeps all non-FILE * descriptors above 255. On all systems
this should make supporting large numbers of vhosts with many open
log files more feasible. If this causes trouble please report it,
you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
[Dean Gaudet] various PRs
*) Related to the last entry, network sockets are now opened before
log files are opened. The only known case where this can cause
problems is under Solaris with many virtualhosts and many Listen
directives. But using -DHIGH_SLACK_LINE=256 described above will
work around this problem. [Dean Gaudet]
*) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
SunOS 4.
*) Improved unix error response logging. [Marc Slemko]
*) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
QSA=query_string_append. Also fixed a nasty bug in per-dir context:
when a URL http://... was used in conjunction with a special
redirect flag, e.g. R=permanent, the permanent status was lost.
[Ronald Tschalaer <Ronald.Tschalaer psi.ch>, Ralf S. Engelschall]

Changes with Apache 1.2
Changes with Apache 1.2b11
*) Fixed open timestamp fd in proxy_cache.c [Chuck Murcko]
*) Added undocumented perl SSI mechanism for -DUSE_PERL_SSI and mod_perl.
[Doug MacEachern, Rob Hartill]
*) Proxy needs to use hard_timeout instead of soft_timeout when it is
reading from one buffer and writing to another, at least until it has
a custom timeout handler. [Roy Fielding and Petr Lampa]
*) Fixed problem on IRIX with servers hanging in IdentityCheck,
apparently due to a mismatch between sigaction and setjmp.
[Roy Fielding] PR#502
*) Log correct status code if we timeout before receiving a request (408)
or if we received a request-line that was too long to process (414).
[Ed Korthof and Roy Fielding] PR#601
*) Virtual hosts with the same ServerName, but on different ports, were
not being selected properly. [Ed Korthof]
*) Added code to return the requested IP address from proxy_host2addr()
if gethostbyaddr() fails due to reverse DNS lookup problems. Original
change submitted by Jozsef Hollosi <hollosi sbcm.com>.
[Chuck Murcko] PR#614
*) If multiple requests on a single connection are used to retrieve
data from different virtual hosts, the virtual host list would be
scanned starting with the most recently used VH instead of the first,
causing most virtual hosts to be ignored.
[Paul Sutton and Martin Mares] PR#610
*) The OS/2 handling of process group was broken by a porting patch for
MPE, so restored prior code for OS/2. [Roy Fielding and Garey Smiley]
*) Inherit virtual server port from main server if none (or "*") is
given for VirtualHost. [Dean Gaudet] PR#576
*) If the lookup for a DirectoryIndex name with content negotiation
has found matching variants, but none are acceptable, return the
negotiation result if there are no more DirectoryIndex names to lookup.
[Petr Lampa and Roy Fielding]
*) If a soft_timeout occurs after keepalive is set, then the main child
loop would try to read another request even though the connection
has been aborted. [Roy Fielding]
*) Configure changes: Allow for whitespace at the start of a
Module declaration. Also, be more understanding about the
CC=/OPTIM= format in Configuration. Finally, fix compiler
flags if using HP-UX's cc compiler. [Jim Jagielski]
*) Subrequests and internal redirects now inherit the_request from the
original request-line. [Roy Fielding]
*) Test for error conditions before creating output header fields, since
we don't want the error message to include those fields. Likewise,
reset the content_language(s) and content_encoding of the response
before generating or redirecting to an error message, since the new
message will have its own Content-* definitions. [Dean Gaudet]
*) Restored the semantics of headers_out (headers sent only with 200..299
and 304 responses) and err_headers_out (headers sent with all responses).
Avoid the overhead of copying tables if err_headers_out is empty
(the usual case). [Roy Fielding]
*) Fixed a couple places where a check for the default Content-Type was
not properly checking both the value configured by the DefaultType
directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
of DEFAULT_TYPE to match the documented default (text/plain).
[Dean Gaudet] PR#506
*) Escape the HTML-sensitive characters in the Request-URI that is
output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
*) Properly initialize the flock structures used by the mutex locking
around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
[Marc Slemko]
*) The method for determining PATH_INFO has been restored to the pre-1.2b
(and NCSA httpd) definition wherein it was the extra path info beyond
the CGI script filename. The environment variable FILEPATH_INFO has
been removed, and instead we supply the original REQUEST_URI to any
script that wants to be Apache-specific and needs the real URI path.
This solves a problem with existing scripts that use extra path info
in the ScriptAlias directive to pass options to the CGI script.
[Roy Fielding]
*) The _default_ change in 1.2b10 will change the behaviour on configs
that use multiple Listen statements for listening on multiple ports.
But that change is necessary to make _default_ consistent with other
forms of <VirtualHost>. It requires such configs to be modified
to use <VirtualHost _default_:*>. The documentation has been
updated. [Dean Gaudet] PR#530
*) If an ErrorDocument CGI script is used to respond to an error
generated by another CGI script which has already read the message
body of the request, the server would block trying to read the
message body again. [Rob Hartill]
*) signal() replacement conflicted with a define on QNX (and potentially
other platforms). Fixed. [Ben Laurie] PR#512
Changes with Apache 1.2b10
*) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
to be configured via -D in Configuration. [Dean Gaudet] PR#449

*) In mod_proxy.c, check return values for proxy_host2addr() when reading
config, in case the hostent struct returned is trash.
[Chuck Murcko] PR #491
*) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
Changes with Apache 1.2b9 [never announced]
*) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
changes and in anticipation of 1.2 final release. [Roy Fielding]
*) Fix problem with scripts not receiving a SIGPIPE when client drops
the connection (e.g., when user presses Stop). Apache will now stop
trying to send a message body immediately after an error from write.
[Roy Fielding and Nathan Kurz] PR#335
*) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
than mod_alias, and mod_alias has higher priority than mod_proxy;
rearranged other modules to enhance understanding of their purpose
and relative order (and maybe even reduce some overhead).
[Roy Fielding and Sameer Parekh]
*) Fix graceful restart. Eliminate many signal-related race
conditions in both forms of restart, and in SIGTERM. See
htdocs/manual/stopping.html for details on stopping and
restarting the parent. [Dean Gaudet]
*) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
memory allocator to avoid a behaviour that required extra blocks to

PR#367, 368, 354, 453
*) Fix the above fix: if suexec is enabled, avoid destroying r->url
while obtaining the /~user and save the username in a separate data
area so that it won't be overwritten by the call to getgrgid(), and
fix some misuse of the pool string allocation functions. Also fixes
a general problem with parsing URL query info into args for CGI scripts.
[Roy Fielding] PR#339, 367, 354, 453
*) Fix IRIX warning about bzero undefined. [Marc Slemko]
*) Fix problem with <Directory proxy:...>. [Martin Kraemer] PR#271
*) Corrected spelling of "authoritative". AuthDBAuthoratative became
AuthDBAuthoritative. [Marc Slemko] PR#420
*) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
*) The default handler now logs invalid methods or URIs (i.e. PUT on an
object that can't be PUT, or FOOBAR for some method FOOBAR that
apache doesn't know about at all). Log 404s that occur in mod_include.
[Paul Sutton, John Van Essen]
*) If a soft timeout (or lingerout) occurs while trying to flush a
buffer or write inside buff.c or fread'ing from a CGI's output,
then the timeout would be ignored. [Roy Fielding] PR#373
*) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
parsing of headers. If the terminating empty-line CRLF occurs starting
at the 256th or 257th byte of output, then Navigator will think a normal
image is invalid. We are guessing that this is because their initial
read of a new request uses a 256 byte buffer. We check the bytes written
so far and, if we are about to tickle the bug, we instead insert a
padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
*) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
of an external redirection. [Roy Fielding and Paul Sutton]
*) Configure would create a broken Makefile if the configuration file
contained a commented-out Rule. [Roy Fielding]
*) Promote per_dir_config and subprocess_env from the subrequest to the
main request in mod_negotiation. In particular this fixes a bug
where <Files> sections wouldn't properly apply to negotiated content.
[Dean Gaudet]
*) Fix a potential deadlock in mod_cgi script_err handling.
[Ralf S. Engelschall]
*) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
[Mitchell Blank Jr]
*) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
.htaccess files because the RewriteBase was not replaced correctly.
Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
<Directory> sections missing a trailing /. [Ralf S. Engelschall]
*) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
1.x the settings are those of pre-1.2b8. For 2.x we include
USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
HAVE_SYS_RESOURCE_H (enable the RLimit commands).
[Dean Gaudet] PR#336, PR#340
*) Redirect did not preserve ?query_strings when present in the client's
request. [Dean Gaudet]
*) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
*) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
*) Add UnixWare compile/install instructions. [Chuck Murcko]

*) Improve handling of directories when filenames have spaces in them.
[Chuck Murcko]
*) For hosts with multiple IP addresses, try all additional addresses if
necessary to get a connect. Fail only if hostent address list is
exhausted. [Chuck Murcko]
*) More signed/unsigned port fixes. [Dean Gaudet]
*) HARD_SERVER_LIMIT can be defined in the Configuration file now.
[Dean Gaudet]
Changes with Apache 1.2b8
*) suexec.c doesn't close the log file, allowing CGIs to continue writing
to it. [Marc Slemko]
*) The addition of <Location> and <File> directives made the
sub_req_lookup_simple() function bogus, so we now handle
the special cases directly. [Dean Gaudet]
*) We now try to log where the server is dumping core when a fatal
signal is received. [Ken Coar]
*) Improved lingering_close by adding a special timeout, removing the
spurious log messages, removing the nonblocking settings (they
are not needed with the better timeout), and adding commentary
about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
*) Send error messages about setsockopt failures to the server error
log instead of stderr. [Roy Fielding]
*) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
*) Stopgap solution for CGI 3-second delay with server-side includes: if
processing a subrequest, allocate memory from r->main->pool instead
of r->pool so that we can avoid waiting for free_proc_chain to cleanup
in the middle of an SSI request. [Dean Gaudet] PR #122
*) Fixed status of response when POST is received for a nonexistent URL
(was sending 405, now 404) and when any method is sent with a
full-URI that doesn't match the server and the server is not acting
as a proxy (was sending 501, now 403). [Roy Fielding]
*) Host port changed to unsigned short. [Ken Coar] PR #276
*) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
*) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
*) Report extra info from errno with many errors that cause httpd to exit.
spawn_child, popenf, and pclosef now have valid errno returns in the
event of an error. Correct problems where errno was stomped on
before being reported. [Dean Gaudet]
*) In the proxy, if the cache filesystem was full, garbage_coll() was
never called, and thus the filesystem would remain full indefinitely.
We now also remove incomplete cache files left if the origin server
didn't send a Content-Length header and either the client has aborted
transfer or bwrite() to client has failed. [Petr Lampa]
*) Fixed the handling of module and script-added header fields.
Improved the interface for sending header fields and reduced
the duplication of code between sending okay responses and errors.
We now always send both headers_out and err_headers_out, and
ensure that the server-reserved fields are not being overridden,
while not overriding those that are not reserved. [Roy Fielding]
*) Moved transparent content negotiation fields to err_headers_out
to reflect above changes. [Petr Lampa]
*) Fixed the determination of whether or not we should make the
connection persistent for all of the cases where some other part
of the server has already indicated that we should not. Also
improved the ordering of the test so that chunked encoding will
be set whenever it is desired instead of only when KeepAlive
is enabled. Added persistent connection capability for most error
responses (those that do not indicate a bad input stream) when
accessed by an HTTP/1.1 client. [Roy Fielding]
*) Added missing timeouts for sending header fields, error responses,
and the last chunk of chunked encoding, each of which could have
resulted in a process being stuck in write forever. Using soft_timeout
requires that the sender check for an aborted connection rather than
continuing after an EINTR. Timeouts that used to be initiated before
send_http_header (and never killed) are now initiated only within or
around the routines that actually do the sending, and not allowed to
propagate above the caller. [Roy Fielding]
*) mod_auth_anon required an @ or a . in the email address, not both.
[Dirk vanGulik]
*) per_dir_defaults weren't set correctly until directory_walk for
name-based vhosts. This fixes an obscure bug with the wrong config
info being used for vhosts that share the same ip as the server.
[Dean Gaudet]
*) Improved generation of modules/Makefile to be more generic for
new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
*) Generate makefile dependency for Configuration based on the actual
name given when running the Configure process. [Dean Gaudet]
*) Fixed problem with vhost error log not being set prior to
initializing virtual hosts. [Dean Gaudet]
*) Fixed infinite loop when a trailing slash is included after a type map
file URL (extra path info). [Petr Lampa]
*) Fixed server status updating of per-connection counters. [Roy Fielding]
*) Add documentation for DNS issues (reliability and security), and try
to explain the virtual host matching process. [Dean Gaudet]
*) Try to continue gracefully by disabling the vhost if a DNS lookup
fails while parsing the configuration file. [Dean Gaudet]
*) Improved calls to setsockopt. [Roy Fielding]
*) Negotiation changes: Don't output empty content-type in variant list;
Output charset in variant list; Return sooner from handle_multi() if
no variants found; Add handling of '*' wildcard in Accept-Charset.
[Petr Lampa and Paul Sutton]
*) Fixed overlaying of request/sub-request notes and headers in
mod_negotiation. [Dean Gaudet]
*) If two variants' charset quality are equal and one is the default
charset (iso-8859-1), then prefer the variant that was specifically
listed in Accept-Charset instead of the default. [Petr Lampa]
*) Memory allocation problem in push_array() -- it would corrupt memory
when nalloc==0. [Kai Risku <krisku tf.hut.fi> and Roy Fielding]
*) invoke_handler() doesn't handle mime arguments in content-type
[Petr Lampa] PR#160
*) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
[Ken Coar]
*) Fixed problem with ErrorDocument not working for virtual hosts
due to one of the performance changes in 1.2b7. [Dean Gaudet]
*) Log an error message if we get a request header that is too long,
since it may indicate a buffer overflow attack. [Marc Slemko]
*) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
not reject URLs without a double-slash, as per RFC2068 section 3.2.
[Ken Coar] PR #146, #187
*) Added table entry placeholder for new header_parser callback
in all of the distributed modules. [Ken Coar] PR #191
*) Allow for cgi files without the .EXE extension on them under OS/2.
[Garey Smiley] PR #59
*) Fixed error message when resource is not found and URL contains
path info. [Petr Lampa and Dean Gaudet] PR #40
*) Fixed user and server confusion over what should be a virtual host
and what is the main server, resulting in access to something
other than the name defined in the virtualhost directive (but
with the same IP address) failing. [Dean Gaudet]
*) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
AIX; improves the redirection stuff to enable the users to generally
redirect to http, https, gopher and ftp; added TIME variable for
RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
special patterns >STRING, <STRING and =STRING to RewriteCond, which
can be used in conjunction with %{TIME} or other variables to create
time-dependent rewriting rules. [Ralf S. Engelschall]
*) bpushfd() no longer notes cleanups for the file descriptors it is handed.
Module authors may need to adjust their code for proper cleanup to take
place (that is, call note_cleanups_for_fd()). This change fixes problems
with file descriptors being erroneously closed when the proxy module was
in use. [Ben Laurie]
*) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
initgroups() to hose the group information needed for later
comparisons. [Randy Terbush]
*) Remove unnecessary call to va_end() in create_argv() which
caused a SEGV on some systems.
*) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
[Dean Gaudet]
*) Clear memory allocated for listeners. [Randy Terbush]
*) Improved handling of IP address as a virtualhost address and
introduced "_default_" as a synonym for the default vhost config.

- replace protocol response numbers with symbols
- save variant-list into main request notes
- free allocated memory from subrequests
- merge notes, headers_out and err_headers_out
*) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
"HTTP/#.# ###*" to be more lenient about what we accept.
[Chuck Murcko]
*) more proxy FTP bug fixes:
- Changed send_dir() to remove user/passwd from displayed URL.
- Changed login error messages to be more descriptive.
- remove setting of SO_DEBUG socket option
- Make ftp_getrc() more lenient about multiline responses,
specifically, 230 responses which don't have continuation 230-
on each line). These seem to be all NT FTP servers, and while
perhaps questionable, they appear to be legal by RFC 959.
- Add missing kill_timeout() after transfer to user completes.
[Chuck Murcko]
*) Fixed problem where a busy server could hang when restarting
after being sent a SIGHUP due to child processes not exiting.
[Marc Slemko]
*) Modify mod_include escaping so a '\' only signifies an escaped
character if the next character is one that needs
escaping. [Ben Laurie]
*) Eliminated possible infinite loop in mod_imap when relative URLs are
used with a 'base' directive that does not have a '/' in it.
[Marc Slemko, reported by Onno Witvliet <onno tc.hsa.nl>]
*) Reduced the default timeout from 1200 seconds to 300, and the
one in the sample configfile from 400 to 300. [Marc Slemko]
*) Stop vbprintf from crashing if given a NULL string pointer;
print (null) instead. [Ken Coar]
*) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
[Marc Slemko and Roy Fielding]
*) Fixed problem with mod_cgi-generated internal redirects trying to
read the request message-body twice. [Archie Cobbs and Roy Fielding]
*) Reduced timeout on lingering close, removed possibility of a blocked
read causing the child to hang, and stopped logging of errors if
the socket is not connected (reset by client). [Roy Fielding]
*) Rearranged main child loop to remove duplication of code in
select/accept and keep-alive requests, fixed several bugs regarding
checking scoreboard_image for exit indication and failure to
account for all success conditions and trap all error conditions,
prevented multiple flushes before closing the socket; close the entire
socket buffer instead of just one descriptor, prevent logging of
EPROTO and ECONNABORTED on platforms where supported, and generally
improved readability. [Roy Fielding]
*) Extensive performance improvements. Cleaned up inefficient use of
auto initializers, multiple is_matchexp calls on a static string,
and excessive merging of response_code_strings. [Dean Gaudet]
*) Added double-buffering to mod_include to improve performance on
server-side includes. [Marc Slemko]
*) Several fixes for suexec wrapper. [Randy Terbush]
- Make wrapper work for files on NFS filesystem.
- Fix portability problem of MAXPATHLEN.
- Fix array overrun problem in clean_env().
- Fix allocation of PATH environment variable
*) Removed extraneous blank line is description of mod_status chars.
[Kurt Kohler]
*) Logging of errors from the call_exec routine simply went nowhere,
since the logfile fd has been closed, so now we send them to stderr.
[Harald T. Alvestrand]
*) Fixed core dump when DocumentRoot is a CGI.
[Ben Laurie, reported by <geddis tesserae.com>]
*) Fixed potential file descriptor leak in mod_asis; updated it and
http_core to use pfopen/pfclose instead of fopen/fclose.
[Randy Terbush and Roy Fielding]
*) Fixed handling of unsigned ints in ap_snprintf() on some chips such
as the DEC Alpha which is 64-bit but uses 32-bit ints.
[Dean Gaudet and Ken Coar]
*) Return a 302 response code to the client when sending a redirect
due to a missing trailing '/' on a directory instead of a 301; now
it is cacheable. [Markus Gyger]
*) Fix condition where, if a bad directive occurs in .htaccess, and
sub_request() goes first to this directory, then log_reason() will
SIGSEGV because it doesn't have initialized r->per_dir_config.
[PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
*) Fix handling of lang_index in is_variant_better(). This was
causing problems which resulted in the server sending the
wrong language document in some cases. [Petr Lampa]
*) Remove free() from clean_env() in suexec wrapper. This was nuking
the clean environment on some systems.
*) Tweak byteserving code (e.g. serving PDF files) to work around
bugs in Netscape Navigator and Microsoft Internet Explorer.
Emit Content-Length header when sending multipart/byteranges.
[Alexei Kosut]
*) Port to HI-UX/WE2. [Nick Maclaren]
*) Port to HP MPE operating system for HP 3000 machines
[Mark Bixby <markb cccd.edu>]
*) Fixed bug which caused a segmentation fault if only one argument
given to RLimit* directives. [Ed Korthof]
*) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
*) Improved buffered output to the client by delaying the flush decision
until the BUFF code is actually about to read the next request.
This fixes a problem introduced in 1.2b5 with clients that send
an extra CRLF after a POST request. Also improved chunked output
performance by combining writes using writev() and removing as
many bflush() calls as possible. NOTE: Platforms without writev()
must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
or Configure, unless we have already done so. [Dean Gaudet]
*) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
*) Fixed mod_info output corruption bug introduced by buffer overflow
fixes. [Dean Gaudet]
*) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
for the special case of a 304 response. [Paul Sutton]
*) Improved handling of TRACE method by bypassing normal method handling
and header parsing routines; fixed Allow response to always allow TRACE.
[Dean Gaudet]
*) Fixed compiler warnings in the regex library. [Dean Gaudet]
*) Cleaned-up some of the generated HTML. [Ken Coar]
Changes with Apache 1.2b6
*) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
*) Fix typo introduced in fix for potential infinite loop around
accept() in child_main(). This change caused the rev to 1.2b6.
1.2b5 was never a public beta.
Changes with Apache 1.2b5
*) Change KeepAlive semantics (On|Off instead of a number), add
MaxKeepAliveRequests directive. [Alexei Kosut]
*) Various NeXT compilation patches, as well as a change in
regex/regcomp.c since that file also used a NEXT define.
[Andreas Koenig]
*) Allow * to terminate the end of a directory match in mod_dir.
Allows /~* to match for both /~joe and /~joe/. [David Bronder]
*) Don't call can_exec() if suexec_enabled. Calling this requires
scripts executed by the suexec wrapper to be world executable, which
defeats one of the advantages of running the wrapper. [Randy Terbush]
*) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
[Jim Jagielski]
*) Migration from sprintf() to snprintf() to avoid buffer
overflows. [Marc Slemko]
*) Provide portable snprintf() implementation (ap_snprintf)
as well as *cvt family. [Jim Jagielski]
*) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
[Jim Jagielski]
*) Remove mod_fastcgi.c from the distribution. This module appears
to be maintained more through the Open Market channels and should
continue to be easily available at http://www.fastcgi.com/
*) Fixed bug in modules/Makefile that wouldn't allow building in more
than one subdirectory (or cleaning, either). [Jeremy Laidman]
*) mod_info assumed that the config files were relative to ServerRoot.
[Ken the Rodent]
*) CGI scripts called as an error document resulting from failed
CGI execution would hang waiting for POST'ed data. [Rob Hartill]
*) Log reason when mod_dir returns access HTTP_FORBIDDEN
[Ken the Rodent]
*) Properly check errno to prevent display of a directory index
when server receives a long enough URL to confuse stat().
[Marc Slemko]
*) Several security enhancements to suexec wrapper. It is _highly_
recommended that previously installed versions of the wrapper
be replaced with this version. [Randy Terbush, Jason Dour]
- ~user execution now properly restricted to ~user's home
directory and below.
- execution restricted to UID/GID > 100
- restrict passed environment to known variables
- call setgid() before initgroups() (portability fix)
- remove use of setenv() (portability fix)
*) Add HTTP/1.0 response forcing. [Ben Laurie]
*) Add access control via environment variables. [Ben Laurie]
*) Add rflush() function. [Alexei Kosut]
*) remove duplicate pcalloc() call in new_connection().
*) Fix incorrect comparison which could allow number of children =
MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
*) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
AIX PS/2, CONVEXOS. [Jim Jagielski]
*) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
It's more portable. [Martin Kraemer]
*) Replace references to make in Makefile.tmpl with $(MAKE).
[Chuck Murcko]
*) Add ProxyBlock directive w/IP address caching. Add IP address
caching to NoCache directive as well. ProxyBlock works with all
handlers; NoCache now also works with FTP for anonymous logins.
Still more code cleanup. [Chuck Murcko]
*) Add "header parse" API hook [Ben Laurie]
*) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
*) suEXEC wrapper was freeing memory that had not been malloc'ed.
*) Correctly allow access and auth directives in <Files> sections in
server config files. [Alexei Kosut]
*) Fix bug with ServerPath that could cause certain files to be not
found by the server. [Alexei Kosut]
*) Fix handling of ErrorDocument so that it doesn't remove a trailing
double-quote from text and so that it properly checks for unsupported
status codes using the new index_of_response interface. [Roy Fielding]
*) Multiple fixes to the lingering_close code in order to avoid being
interrupted by a stray timeout, to avoid lingering on a connection
that has already been aborted or never really existed, to ensure that
we stop lingering as soon as any error condition is received, and to
prevent being stuck indefinitely if the read blocks. Also improves
reporting of error conditions. [Marc Slemko and Roy Fielding]
*) Fixed initialization of parameter structure for sigaction.
[<mgyger itr.ch>, Adrian Filipi-Martin]
*) Fixed reinitializing the parameters before each call to accept and
select, and removed potential for infinite loop in accept.
[Roy Fielding, after useful PR from <adrian virginia.edu>]
*) Fixed condition where, if a child fails to fork, the scoreboard would
continue to say SERVER_STARTING forever. Eventually, the main process
would refuse to start new children because count_idle_servers() will
count those SERVER_STARTING entries and will always report that there
are enough idle servers. [Phillip Vandry]
*) Fixed bug in bcwrite regarding failure to account for partial writes.
Avoided calling bflush() when the client is pipelining requests.
Removed unnecessary flushes from http_protocol. [Dean Gaudet]
*) Added description of "." mode in server-status [Jim Jagielski]
Changes with Apache 1.2b4
*) Fix possible race condition in accept_mutex_init() that
could leave a small security hole open allowing files to be
overwritten in cases where the server UID has write permissions.
[Marc Slemko]
*) Fix awk compatibilty problem in Configure. [Jim Jagielski]
*) Fix portablity problem in util_script where ARG_MAX may not be
defined for some systems.
*) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
[Randal Schwartz]
*) OS/2 changes to support an MMAP style scoreboard file and UNIX
style magic #! token for better script portability. [Garey Smiley]
*) Fix bug in suexec wrapper introduced in b3 that would cause failed
execution for ~userdir CGI. [Jason Dour]
*) Fix initgroups() business in suexec wrapper. [Jason Dour]
*) Fix month off by one in suexec wrapper logging.
Changes with Apache 1.2b3:
*) Fix error in mod_cgi which could cause resources not to be properly
freed, or worse. [Dean Gaudet]
*) Fix find_string() NULL pointer dereference. [Howard Fear]
*) Add set_flag_slot() at the request of Dirk and others.
[Dirk vanGulik]
*) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
*) Add changes to improve the error message given for invalid
ServerName parameters. [Dirk vanGulik]
*) Add "Authoritative" directive for Auth modules that don't
currently have it. This gives admin control to assign authoritative
control to an authentication scheme and allow "fall through" for
those authentication modules that aren't "Authoritative" thereby
allowing multiple authentication mechanisms to be chained.
[Dirk vanGulik]
*) Remove requirement for ResourceConfig/AccessConfig if not using
the three config file layout. [Randy Terbush]
*) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
*) Changes to suexec wrapper to fix the following problems:
1. symlinked homedirs will kill ~userdirs.
2. initgroups() on Linux 2.0.x clobbers gr->grid.
3. CGI command lines paramters problems
4. pw-pwdir for "docroot check" still the httpd user's pw record.
[Randy Terbush, Jason Dour]
*) Change create_argv() to accept variable arguments. This fixes
a problem where arguments were not getting passed to the CGI via
argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
*) Collapse multiple slashes in path URLs to properly apply
handlers defined by <Location>. [Alexei Kosut]
*) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
*) Improve the accuracy of request duration timings by setting
r->request_time in read_request_line() instead of read_request().
[Dean Gaudet]
*) Reset timeout while reading via get_client_block() in mod_cgi.c
Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
*) Add the ability to pass different Makefile.tmpl files to Configure
using the -make flag. [Rob Hartill]
*) Fix coredump triggered when sending a SIGHUP to the server caused
by an assertion failure, in turn caused by an uninitialised field in a
listen_rec.
[Ben Laurie]
*) Add FILEPATH_INFO variable to CGI environment, which is equal to
PATH_INFO from previous versions of Apache (in certain situations,
Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
[later removed in 1.2b11]
*) Add rwrite() function to API to allow for sending strings of
arbitrary length. [Doug MacEachern]
*) Remove rlim_t typedef for NetBSD. Do older versions need this?
*) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
NeXT. [Jim Jagielski]
*) Removed recent modification to promote the status code on internal
redirects, since the correct fix was to change the default log format
in mod_log_config so that it outputs the original status. [Rob Hartill]
Changes with Apache 1.2b2:
*) Update set_signals() to use sigaction() for setting handlers.
This appears to fix a re-entrant problem in the seg_fault()
bus_error() handlers. [Randy Terbush]
*) Changes to allow mod_status compile for OS/2 [Garey Smiley]
*) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
*) proxy_http.c bugfixes: [Chuck Murcko]
1) fixes possible NULL pointer reference w/NoCache
2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
host would cache nothing if it was in the local domain,
and the local domain was in the NoCache list)
3) Adds Host: header when not available
4) Some code cleanup and clarification
*) mod_include.c bugfixes:
1) Fixed an ommission that caused include variables to not
be parsed in config errmsg directives [Howard Fear]
2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
3) Patch to fix compiler warnings [<perrot lal.in2p3.fr>]
4) Allow backslash-escaping to all quoted text
[Ben Yoshino <ben wiliki.eng.hawaii.edu>]
5) Pass variable to command line if not set in XSSI's env
[Howard Fear]
*) Fix infinite loop when processing Content-language lines in
type-map files. [Alexei Kosut]
*) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
*) Fixed problem in set_[user|group] that prevented CGI execution
for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
*) Added PORTING information file. [Jim Jagielski]
*) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
*) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
*) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
USE_FCNTL_SERIALIZED_ACCEPT was intended.
*) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
which caused problems of systems where socket s_addr is >32bits.
*) Added comment to explain (r->chunked = 1) side-effect in
http_protocol.c [Roy Fielding]
*) Replaced use of index() in mod_expires.c with more appropriate
and portable isdigit() test. [Ben Laurie]
*) Updated Configure for ...
OS/2 (DEF_WANTHSREGEX=yes, other code changes)
*-dg-dgux* (bad pattern match)
QNX (DEF_WANTHSREGEX=yes)
*-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
*-ultrix (new)
*-unixware211 (new)
and added some user diagnostic info. [Ben Laurie]
*) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
for better portability. [Jim Jagielski]
*) Updated helpers/GuessOS for ...

IRIX64 (-sgi-irix64)
ULTRIX (-unknown-ultrix)
SINIX (-whatever-sysv4)
NCR Unix (-ncr-sysv4)
and fixed something in helpers/PrintPath [Ben Laurie]
Changes with Apache 1.2b1

c) Leading colons were stripped from passwords [<osm interguide.com>]
d) Another fix to multi-method Limit problem [<jk tools.de>]
Changes with Apache 1.1b4

b) early termination of inetd requests
c) compile warnings on several systems
d) problems when scripts stop reading output early
Changes with Apache 1.1b3
*) Much of cgi-bin and all of cgi-src has been removed, due to
various security holes found and that we could no longer support
them.
*) The "Set-Cookie" header is now special-cased to not merge multiple
instances, since certain popular browsers can not handle multiple
Set-Cookie instructions in a single header. [Paul Sutton]
*) rprintf() added to buffer code, occurrences of sprintf removed.
[Ben Laurie]
*) CONNECT method for proxy module, which means tunneling SSL should work.
(No crypto needed) Also a NoCache config directive.
*) Several API additions: pstrndup(), table_unset() and get_token()
functions now available to modules.
*) mod_imap fixups, in particular Location: headers are now complete
URL's.
*) New "info" module which reports on installed module set through a
special URL, a la mod_status.
*) "ServerPath" directive added - allows for graceful transition
for Host:-header-based virtual hosts.
*) Anonymous authentication module improvements.
*) MSQL authentication module improvements.
*) Status module design improved - output now table-based. [Ben Laurie]
*) htdigest utility included for use with digest authentication
module.
*) mod_negotiation: Accept values with wildcards to be treated with
less priority than those without wildcards at the same quality
value. [Alexei Kosut]
*) Bugs which were fixed:
a) numerous mod_proxy bugs
b) CGI early-termination bug [Ben Laurie]
c) Keepalives not working with virtual hosts
d) RefererIgnore problems

Changes with Apache 1.1b2
*) Bugfixes:
a) core dumps in mod_digest
b) truncated hostnames/ip address in the logs
c) relative URL's in mod_imap map files
Changes with Apache 1.1b1
*) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
Changes with Apache 1.0.3
*) Internal redirects which occur in mod_dir.c now preserve the
query portion of a request (the bit after the question mark).
[Adam Sussman]
*) Escape active characters '<', '>' and '&' in html output in
directory listings, error messages and redirection links.
[David Robinson]
*) Apache will now work with LynxOS 2.3 and later [Steven Watt]
*) Fix for POSIX compliance in waiting for processes in alloc.c.
[Nick Williams]
*) setsockopt no longer takes a const declared argument [Martijn Koster]
*) Reset timeout timer after each successful fwrite() to the network.
This patch adds a reset_timeout() procedure that is called by
send_fd() to reset the timeout ever time data is written to the net.
[Nathan Schrenk]
*) timeout() signal handler now checks for SIGPIPE and reports
lost connections in a more user friendly way. [Rob Hartill]
*) Location of the "scoreboard" file which used to live in /tmp is
now configurable (for OSes that can't use mmap) via ScoreBoardFile
which works similar to PidFile (in httpd.conf) [Rob Hartill]
*) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
*) the pstrcat call in mod_cookies.c didn't have an ending NULL,
which caused a SEGV with cookies enabled
*) Output warning when MinSpareServers is set to <= 0 and change it to 1
[Rob Hartill]
*) Log the UNIX textual error returned by some system calls, in
particular errors from accept() [David Robinson]
*) Add strerror function to util.c for SunOS4 [Randy Terbush]
Changes with Apache 1.0.2
*) patch to get Apache compiled on UnixWare 2.x, recommended as
a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
*) Fix get_basic_auth_pw() to set the auth_type of the request.
[David Robinson]
*) past changes to http_config.c to only use the
setrlimit function on systems defining RLIMIT_NOFILE
broke the feature on SUNOS4. Now defines HAVE_RESOURCE
for SUNOS and prototypes the needed functions.
*) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
[David Robinson]
*) Fix use of pointer to scratch memory. [Cliff Skolnick]
*) Merge multiple headers from CGI scripts instead of taking last
one. [David Robinson]
*) Add support for SCO 5. [Ben Laurie]
Changes with Apache 1.0.1
*) Silence mod_log_referer and mod_log_agent if not configured
[Randy Terbush]
*) Recursive includes can occur if the client supplies PATH_INFO data
and the server provider uses relative links; as file.html
relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
*) The replacement for initgroups() did not call {set,end}grent(). This
had two implications: if anything else used getgrent(), then
initgroups() would fail, and it was consuming a file descriptor.
[Ben Laurie]
*) On heavily loaded servers it was possible for the scoreboard to get
out of sync with reality, as a result of a race condition.
The observed symptoms are far more Apaches running than should
be, and heavy system loads, generally followed by catastrophic
system failure. [Ben Laurie]
*) Fix typo in license. [David Robinson]
Changes with Apache 1.0.0 23 Nov 1995
*) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
Changes with Apache 0.8.16 05 Nov 1995
*) New man page for 'httpd' added to support directory [David Robinson]
*) .htgroup files can have more than one line giving members for a
given group (each must have the group name in front), for NCSA
back-compatibility [Robert Thau]
*) Mutual exclusion around accept() is on by default for SVR4 systems
generally, since they generally can't handle multiple processes in
accept() on the same socket. This should cure flaky behavior on
a lot of those systems. [David Robinson]
*) AddType, AddEncoding, and AddLanguage directives take multiple
extensions on a single command line [David Robinson]
*) UserDir can be disabled for a given virtual host by saying
"UserDir disabled" in the <VirtualHost> section --- it was a bug
that this didn't work. [David Robinson]
*) Compiles on QNX [Ben Laurie]
*) Corrected parsing of ctime time format [David Robinson]
*) httpd does a perror() before exiting if it can't log its pid
to the PidFile, to make diagnosing the error a bit easier.
[David Robinson]
*) <!--#include file="..."--> can no longer include files in the
parent directory, for NCSA back-compatibility. [David Robinson]
*) '~' is *not* escaped in URIs generated for directory listings
[Roy Fielding]
*) Eliminated compiler warning in the imagemap module [Randy Terbush]
*) Fixed bug involving handling URIs with escaped %-characters
in redirects [David Robinson]
Changes with Apache 0.8.15 14 Oct 1995
*) Switched to new, simpler license
*) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
*) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
*) Reject paths containing %-escaped '%' or null characters [David Robinson]
*) Correctly handles internal redirects to files with names containing '%'
[David Robinson]
*) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
*) Use geteuid() rather than getuid() to see if we have root privilege,
so that server correctly resets privilege if run setuid root. [Andrew
Wilson]
*) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
[Randy Terbush]
*) Fix relative URLs in imagemap files [Randy Terbush]
*) Somewhat better fix for the old "Alias /foo/ /bar/" business
[David Robinson]
*) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
entries all name the same one. [David Robinson]
*) Fix directory listings with filenames containing unusual characters
[David Robinson]
*) Better URI-escaping for generated URIs in directories with filenames
containing unusual characters [Ben Laurie]
*) Fixed potential FILE* leak in http_main.c [Ben Laurie]
*) Unblock alarms on error return from spawn_child() [David Robinson]
*) Sample Config files have extra note for SCO users [Ben Laurie]
*) Configuration has note for HP-UX users [Rob Hartill]
*) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
*) Nuked bogus #define in httpd.h [David Robinson]
*) Better test for whether a system has setrlimit() [David Robinson]
*) Calls update_child_status() after reopen_scoreboard() [David Robinson]
*) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
[Ben Laurie]
Changes with Apache 0.8.14 19 Sep 1995
*) Compiles on SCO ODT 3.0 [Ben Laurie]
*) AddDescription works (better) [Ben Laurie]
*) Leaves an intelligible error diagnostic when it can't set group
privileges on standalone startup [Andrew Wilson]
*) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
that machine, which claims to be BSD but does not support RLIMIT.
[Randy Terbush]
*) gcc -Wall no longer complains about an unused variable when util.c
is compiled with -DMINIMAL_DNS [Andrew Wilson]
*) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
Changes with Apache 0.8.13 07 Sep 1995
*) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
*) Have built-in imagemap code recognize & honor Point directive [James
Cloos]
*) Generate cleaner directory listings in directories with a mix of
long and short filenames [Rob Hartill]
*) Properly initialize dynamically loaded modules [Royston Shufflebotham]
*) Properly default ServerName for virtual servers [Robert Thau]
*) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
Paul Richards and a cast of thousands...]
*) On self-identified BSD systems (we don't try to guess any more),
allocate a few extra file descriptors per virtual host with setrlimit,
if we can, to avoid running out. [Randy Terbush]
*) Write 22-character lock file name into buffer with enough space
on startup [Konstantin Olchanski]
*) Use archaic setpgrp() interface on NeXT, which requires it [Brian
Pinkerton]
*) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
*) Suppress -Wall warning by initializing variable in negotiation code
[Tobias Weingartner]
Changes with Apache 0.8.12 31 Aug 1995
*) Doesn't pause three seconds after including a CGI script which is
too slow to die off (this is done by not even trying to kill off
subprocesses, including the SIGTERM/pause/SIGKILL routine, until
after the entire document has been processed). [Robert Thau]
*) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
*) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
*) Allows .htaccess files to override <Directory> sections naming the
same directory [David Robinson]
*) Removed an efficiency hack in sub_req_lookup_uri which was
causing certain extremely marginal cases (e.g., ScriptAlias of a
*particular* index.html file) to fail. [David Robinson]
*) Doesn't log an error when the requested URI requires
authentication, but no auth header line was supplied by the
client; this is a normal condition (the client doesn't no auth is
needed here yet). [Robert Thau]
*) Behaves more sanely when the name server loses its mind [Sean Welch]
*) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
*) RFC931 code no longer passes out name of prior clients on current
requests if the current request came from a server that doesn't
do RFC931. [David Robinson]
*) Configuration script accepts "Module" lines with trailing whitespace.
[Robert Thau]
*) Cleaned up compiler warning from mod_access.c [Robert Thau]
*) Cleaned up comments in mod_cgi.c [Robert Thau]
Changes with Apache 0.8.11 24 Aug 1995
*) Wildcard <Directory> specifications work. [Robert Thau]
*) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
*) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
the file being requested itself, in addition to the directories leading
up to it. [Robert Thau]
*) Logs access failures due to symlink checks or invalid client address
in the error log [Roy Fielding, Robert Thau]
*) Symlink checks deal correctly with systems where lstat of
"/path/to/some/link/" follows the link. [Thau, Fielding]
*) Doesn't reset DirectoryIndex to 'index.html' when
other directory options are set in a .htaccess file. [Robert Thau]
*) Clarified init code and nuked bogus warning in mod_access.c
[Florent Guillaume]
*) Corrected several directives in sample srm.conf
--- includes corrections to directory indexing icon-related directives
(using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
icons for encodings right, and turning on AddEncoding by default).
[Roy Fielding]
*) Corrected descriptions of args to AddIcon and AddAlt in command table
[James Cloos]
*) INSTALL & README mention "contributed modules" directory [Brian
Behlendorf]
*) Fixed English in the license language... "for for" --> "for".
[Roy Fielding]
*) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
mod_alias.c, merging it almost completely with handling of Alias, and
adding a 'notes' field to the request_rec which allows the CGI module
to discover whether the Alias module has put this request through
ScriptAlias (which it needs to know for back-compatibility, as the old
NCSA code did not check Options ExecCGI in ScriptAlias directories).
[Robert Thau]
Changes with Apache 0.8.10 18 Aug 1995
*) AllowOverride applies to the named directory, and not just
subdirectories. [David Robinson]
*) Do locking for accept() exclusion (on systems that need it)
using a special file created for the purpose in /usr/tmp, and
not the error log; using the error log causes real problems
if it's NFS-mounted; this is known to be the cause of a whole
lot of "server hang" problems with Solaris. [David Robinson;
thanks to Merten Schumann for help diagnosing the problem].
Changes with Apache 0.8.9 12 Aug 1995
*) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
*) Nested includes see environment variables of the including document,
for NCSA bug-compatibility (some sites have standard footer includes
which try to print out the last-modified date). [Eric Hagberg/Robert
Thau]
*) <!--exec cgi="/some/uri/here"--> always treats the item named by the
URI as a CGI script, even if it would have been treated as something
else if requested directly, for NCSA back-compatibility. (Note that
this means that people who know the name of the script can see the
code just by asking for it). [Robert Thau]
*) New version of dbmmanage script included in support directory as
dbmmanage.new.
*) Check if scoreboard file couldn't be opened, and say so, rather
then going insane [David Robinson]
*) POST to CGI works on A/UX [Jim Jagielski]
*) AddIcon and AddAlt commands work properly [Rob Hartill]
*) NCSA server push works properly --- the Arena bug compatibility
workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
if you still want the workaround). [Rob Hartill]
*) If client didn't submit any Accept-encodings, ignore encodings in
content negotiation. (NB this will all have to be reworked anyway
for the new HTTP draft). [Florent Guillaume]
*) Don't dump core when trying to log timed-out requests [Jim Jagielski]
*) Really honor CacheNegotiatedDocs [Florent Guillaume]
*) Give Redirect priority over Alias, for NCSA bug compatibility
[David Robinson]
*) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
paralleling earlier bug fix for CGI [David Robinson]
*) If DBM auth is improperly configured, report a server error and don't
dump core.
*) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
it seems to work well enough without it (even in a 10 hits/sec
workout), and the overhead for the locking under A/UX is
alarmingly high (though it is very low on other systems).
[Eric Hagberg, Jim Jagielski]
*) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
*) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
Behlendorf/Eric Hagberg]
*) More improvements to default Configuration for A/UX [Jim Jagielski]
*) Compiles clean on NEXT [Rob Hartill]
*) Compiles clean on SGI [Robert Thau]
Changes with Apache 0.8.8 08 Aug 1995
*) SunOS library prototypes now never included unless explicitly
requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
people using GNU libc on SunOS are screwed by prototypes for the
standard library.
(Those who wish to compile clean with gcc -Wall on a standard
SunOS setup need the prototypes, and may obtain them using
-DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
with nonstandard libraries are presumably competent to make their
own arrangements).
*) Strips trailing '/' characters off both args to the Alias command,
to make 'Alias /foo/ /bar/' work.
Changes with Apache 0.8.7 03 Aug 1995
*) Don't hang when restarting with a child from 'TransferLog "|..."' running
[reported by David Robinson]
*) Compiles clean on OSF/1 [David Robinson]
*) Added some of the more recent significant changes (AddLanguage stuff,
experimental LogFormat support) to CHANGES file in distribution root
directory
Changes with Apache 0.8.6 02 Aug 1995
*) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
(If you actually wanted a conditional GET which bypassed the cache, you
couldn't get it). [Reported by Roy Fielding]
*) Properly terminate headers on '304 Not Modified' replies to conditional
GETs --- no browser we can find cares much, but the CERN proxy chokes.
[Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
*) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
*) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
and older versions don't set the __SUNPRO_C preprocessor variable). On
all other systems, these are never used anyway. [Reported by Mark Cox].
*) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
Changes with Apache 0.8.5 01 Aug 1995
*) Added last-minute configurable log experiment, as optional module
*) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
properly. (One-line fix to http_protocol.c).
*) Work around bogus behavior when reloading from Netscape.
It's Netscape's bug --- for some reason they expect a request with
If-modified-since: to not function as a conditional GET if it also
comes with Pragma: no-cache, which is way out of line with the HTTP
spec (according to Roy Fielding, the redactor).
*) Added parameter to set maximum number of server processes.
*) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
Jim Jagielski]
*) IdentityCheck bugfix [Chuck Murcko].
*) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
*) More sample config file corrections; add extension to AddType for
*.asis, move AddType generic description to its proper place, and
fix miscellaneous typos. [ Alexei Kosut ]
*) Deleted the *other* reference to the regents from the Berkeley
legal disclaimer (everyplace).
*) Nuked Shambhala name from src/README; had already cleaned it out
of everywhere else.
Changes with Apache 0.8.4
*) Changes to server-pool management parms --- renamed current
StartServers to MinSpareServers, created separate StartServers
parameter which means what it says, and renamed MaxServers to
MaxSpareServers (though the old name still works, for NCSA 1.4
back-compatibility). The old names were generally regarded as
too confusing. Also altered "docs" in sample config files.
*) More improvements to default config files ---
sample directives (commented out) for XBitHack, BindAddress,
CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
defaults, AddTypes for send-as-is and imagemap magic types, and
improvements to samples for DirectoryIndex [Alexei Kosut]
*) Yet more improvements to default config files --- changes to
Alexei's sample AddLanguage directives, and sample LanguagePriority
[ Florent Guillaume ]
*) Set config file locations properly if not set in httpd.conf
[ David Robinson ]
*) Don't escape URIs in internal redirects multiple times; don't
do that when translating PATH_INFO to PATH_TRANSLATED either.
[ David Robinson ]
*) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
Changes with Apache 0.8.3
*) Edited distribution README to *briefly* summarize installation
procedures, and give a pointer to the INSTALL file in the src/
directory.
*) Upgraded imagemap script in cgi-bin to 1.8 version from more
recent NCSA distributions.
*) Bug fix to previous bug fix --- if .htaccess file and <Directory>
exist for the same directory, use both and don't segfault. [Reported
by David Robinson]
*) Proper makefile dependencies [David Robinson]
*) Note (re)starts in error log --- reported by Rob Hartill.
*) Only call no2slash() after get_path_info() has been done, to
preserve multiple slashes in the PATH_INFO [NCSA compatibility,
reported by Andrew Wilson, though this one is probably a real bug]
*) Fixed mod_imap.c --- relative paths with base_uri referer don't
dump core when Referer is not supplied. [Randy Terbush]
*) Lightly edited sample config files to refer people to our documentation
instead of NCSA's, and to list Rob McCool as *original* author (also
deleted his old, and no doubt non-functional email address). Would be
nice to have examples of new features...
Changes with Apache 0.8.2 19 Jul 1995
*) Added AddLanuage code [Florent Guillaume]
*) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
*) All sorts of problems when MultiViews finds a directory. It would
be nice if mod_dir.c was robust enough to handle that, but for now,
just punt. [reported by Brian Behlendorf]
*) Wait for all children on restart, to make sure that the old socket
is gone and we can reopen it. [reported by Randy Terbush]
*) Imagemap module is enabled in default Configuration
*) RefererLog and UserAgentLog modules properly default the logfile
[Randy Terbush]
*) Mark Cox's mod_cookies added to the distribution as an optional
module (commented out in the default Configuration, and noted as
an experiment, along with mod_dld). [Mark Cox]
*) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
*) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
*) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
*) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
license]
Changes with Apache 0.8.1
*) New imagemap module [Randy Terbush]
*) Replacement referer log module with NCSA-compatible RefererIgnore
[Matthew Gray again]
*) Don't mung directory listings with very long filenames.
[Florent Guillaume]
Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
*) New config script. See INSTALL for info. [Robert Thau]
*) Scoreboard mechanism for regulating the number of extant server
processes. MaxServers and StartServers defaults are the same as
for NCSA, but the meanings are slightly different. (Actually,
I should probably lower the MaxServers default to 10).
Before asking for a new connection, each server process checks
the number of other servers which are also waiting for a
connection. If there are more than MaxServers, it quietly dies
off. Conversely, every second, the root, or caretaker, process
looks to see how many servers are waiting for a new connection;
if there are fewer than StartServers, it starts a new one. This
does not depend on the number of server processes already extant.
The accounting is arranged through a "scoreboard" file, named
/tmp/htstatus.*, on which each process has an independent file
descriptor (they need to seek without interference).
The end effect is that MaxServers is the maximum number of
servers on an *inactive* server machine, but more will be forked
off to handle unusually heavy loads (or unusually slow clients);
these will die off when they are no longer needed --- without
reverting to the overhead of full forking operation. There is a
hard maximum of 150 server processes compiled in, largely to
avoid forking out of control and dragging the machine down.
(This is arguably too high).
In my server endurance tests, this mechanism did not appear to
impose any significant overhead, even after I forced it to put the
scoreboard file on a normal filesystem (which might have more
overhead than tmpfs). [Robert Thau]
*) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
[Cliff Skolnick]
*) Read .htaccess files even in directory with <Directory> section.
(Former incompatibility noted on mailing list, now fixed). [Robert
Thau]
*) "HEAD /" gives the client a "Bad Request" error message, rather
than trying to send no body *and* no headers. [Cliff Skolnick].
*) Don't produce double error reports for some very obscure cases
mainly involving auth configuration (the "all modules decline to
handle" case which is a sure sign of a server bug in most cases,
but also happens when authentication is badly misconfigured).
[Robert Thau]
*) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
it's *for*, and this sort of thing really shouldn't be cluttering
up the Makefile). [Robert Thau]
*) Incidental code cleanups in http_main.c --- stop dragging
sa_client around; just declare it where used. [Robert Thau]
*) Another acc-related fix. (It doesn't like const char
in some places...). [Mark Cox]
Changes with Shambhala 0.6.1 13 Jul 1995
*) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
Also, fixed auth typo in http_protocol.c unmasked by this fix.
*) Compiles clean with acc on SunOS [Paul Sutton]
*) Reordered modules in modules.c so that Redirect takes priority
over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
believe it or not, he has an actual site with a ScriptAlias and
a Redirect declared for the *exact same directory*. Even *my*
compatibility fetish wouldn't motivate me to fix this if the fix
required any effort, but it doesn't, so what the hey.
*) Fixed to properly default several server_rec fields for virtual
servers from the corresponding fields in the main server_rec.
[Cliff Skolnick --- 'port' was a particular irritant].
*) No longer kills off nph- child processes before they are
finished sending output. [Matthew Gray]
Changes with Shambhala 0.6.0 10 Jul 1995
*) Two styles of timeout --- hard and soft. soft_timeout()s just put
the connection to the client in an "aborted" state, but otherwise
allow whatever handlers are running to clean up. hard_timeout()s
abort the request in progress completely; anything not tied to some
resource pool cleanup will leak. They're still around because I
haven't yet come up with a more elegant way of handling
timeouts when talking to something that isn't the client. The
default_handler and the dir_handler now use soft timeouts, largely
so I can test the feature. [Robert Thau]
*) TransferLog "| my_postprocessor ..." seems to be there. Note that
the case of log handlers dying prematurely is probably handled VERY
gracelessly at this point, and if the logger stops reading input,
the server will hang. (It is known to correctly restart the
logging process on server restart; this is (should be!) going through
the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
script). [Robert Thau]
*) asis files supported (new module). [Robert Thau]
*) IdentityCheck code is compiled in, but has not been tested. (I
don't know anyone who runs identd). [Robert Thau]
*) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
came in with the request, for NCSA bug-compatibility. [Robert Thau]
*) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
*) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
as timeouts are not in scope. [Robert Thau]
*) quoted-string args in config files now handled correctly (doesn't drop
the last character). [Robert Thau; reported by Randy Terbush]
*) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
*) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
default default type); the former default default behavior when all
type-checkers defaulted had been a core dump. [Paul Sutton]
*) Copy filenames out of the struct dirent when indexing
directories. (On Linux, readdir() returns a pointer to the same
memory area every time). Fix is in mod_dir.c. [Paul Sutton]
Changes with Shambhala 0.5.3 [not released]
*) Default response handler notes "file not found" in the error log,
if the file was not found. [Cliff Skolnick].
*) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
code no longer sets up bogus PATH_INFO which fakes out the directory
handler). [Cliff Skolnick]
Changes with Shambhala 0.5.2 06 Jul 1995
*) Changes to http_main.c --- root server no longer plays silly
games with SIGCHLD, and so now detects and replaces dying
children. Child processes just die on SIGTERM, without taking
the whole process group with them. Potential problem --- if any
child process refuses to die, we hang in restart.
MaxRequestsPerChild may still not work, but it certainly works
better than it did before this! [Robert Thau]
*) mod_dir.c bug fixes: ReadmeName and HeaderName
work (or work better, at least); over-long description lines
properly terminated. [Mark Cox]
*) http_request.c now calls unescape_url() more places where it
should [Paul Sutton].
*) More directory handling bugs (reported by Cox)
Parent Directory link is now set correctly. [Robert Thau]
Changes with Shambhala 0.5.1 04 Jul 1995
*) Generalized cleanup interface in alloc.c --- any function can be
registered with alloc.c as a cleanup for a resource pool;
tracking of files and file descriptors has been reimplemented in
terms of this interface, so I can give it some sort of a test.
[Robert Thau]
*) More changes in alloc.c --- new cleanup_for_exec() function,
which tracks down and closes all file descriptors which have been
registered with the alloc.c machinery before the server exec()s a
child process for CGI or <!--#exec-->. CGI children now get
started with exactly three file descriptors open. Hopefully,
this cures the problem Rob H. was having with overly persistent
CGI connections. [Robert Thau]
*) Mutual exclusion around the accept() in child_main() --- this is
required on at least SGI, Solaris and Linux, and is #ifdef'ed in
by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
This uses fcntl(F_SETLK,...) on the error log descriptor because
flock() on that descriptor won't work on systems which have BSD
flock() semantics, including (I think) Linux 1.3 and Solaris.
This does work on SunOS (when the server is idle, only one
process in the pool is waiting on accept()); it *ought* to work
on the other systems. [Robert Thau]
*) FreeBSD and BSDI portability tweaks [Chuck Murcko]
*) sizeof(*sa_client) bugfix from [Rob Hartill]
*) pstrdup(..., NULL) returns NULL, [Randy Terbush]
*) block_alarms() to avoid leaking the DBM* in dbm auth (this should
be unnecessary if I go to the revised timeout-handling scheme).
[Robert Thau]
*) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
string) even if none came in with the request. [Robert Thau]
*) CHANGES file added to distribution ;-).
Changes with Shambhala 0.4.5
*) mod_dld --- early dynamic loading support [rst]
*) Add wildcard content handlers for XBITHACK; default_hander now
invoked with that mechanism (as a handler hanging off mod_core) [rst]
*) XBITHACK supported as a wildcard content-handler, and
configurable at run-time (not just at compile time, as in the
"patchy server" releases) [rst]
Changes with Shambhala 0.4.4 30 Jun 1995
*) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
*) Handle Addtype x/y .z [rst, reported by Cox]
Changes with Shambhala 0.4.3
*) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
synonymous [rst, terbush]
Changes with Shambhala 0.4.1 28 Jun 1995
*) First-cut virtual host implementation; some refit in the config
reading code, and log management, was necessary to support this [rst]
*) Sub-pool machinery, originally added to avoid excessive storage
allocation on listings of large directories (which turned out to
be the problem that the 0.3 storage accounting was added to
find). Subrequests and mod_dir changed to use subpools. [rst]
*) More memory debugging --- free list consistency checks. [rst]
*) Added err_headers to request_rec, with support elsewhere [rst]
*) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
Changes with Shambhala 0.3 19 Jun 1995
*) Switch ONE_PROCESS to a runtime command-line option (-X)
*) Don't compile in mod_ai_backcompat by default
*) Switch name of server from Apache to Shambhala in Makefile
*) Add some accounting routines to track memory usage in the pools,
for debugging
Changes with Shambhala 0.2
*) Set DOCUMENT_ROOT CGI variable
*) Add single-process debugging, as a compile-time option (ONE_PROCESS)
*) Add critical section protection to handling of cleanup structures
in alloc.c [rst]
*) Significant code reorg within the server core to group related
functions together [rst]
*) Correctly handle clients that hang up before sending any request
[rst]
*) Replace dying child processes. [rst]
Changes with Shambhala 0.1 12 Jun 1995
Major rewrite of the pre-existing "patchy server" codebase, by
Robert Thau (rst). Significant portions of the server code, such
as configuration-file handling and HTTP authentication support,
were ripped out and rewritten from scratch. Code that was not
completely rewritten was significantly altered.
Major changes with this release include:
*) Introduction of the module API; in request handling, the central
machinery just dispatches to various modules, which actually do
most of the work. Configuration handling is similar --- modules
declare their own commands, and the central machinery just
dispatches to them.
API features from shambhala/0.1 were substantially unchanged in
Apache 1.0 and 1.1. (1.0 API features not yet present in this
release, such as wildcard handlers and subpools, were added in
subsequent Shambhala releases, and were also generally rst's
work).
*) This release included the following modules:
mod_access (access control --- allow and deny directives),
mod_alias (Alias and Redirect commands),
mod_auth (straight HTTP authentication, based on flat-files)
mod_auth_dbm (same, with dbm files)
mod_cgi (CGI scripts and, in this release, ScriptAlias)
mod_common_log (CLF access logs; later renamed mod_log_common)
mod_dir (directory indexing)
mod_include (server-side includes)
mod_mime (AddType directives)
mod_negotiation (content negotiation)
mod_userdir (support for users' public_html directories)
It also included a mod_ai_backcompat, which was a private hack
for back-compatibility with rst's own AI-lab servers.
All of these modules were substantially complete, and functional
or nearly so (a few, which implemented features not in use at
Thau's site, required patches of a few lines).
*) sub-request machinery, to allow modules to determine how other
modules would assign MIME types to a given file, or optionally
serve its content (this is heavily used by mod_dir, mod_include
and mod_negotiation).
*) Resource pool system for keeping track of memory allocated and
files opened in service of a particular request. Much of the
code in the modules (when they weren't rewrites) was adjusted to
replace a pervasive convention of using fixed-size buffers on
the stack with an equally pervasive convention of using memory
allocated with palloc().
*) Reorganization of data structures associated with a given
request to eliminate use of global variables and the troublesome
unmunge_name function (used in NCSA and early Apache releases to
attempt to determine the URI which mapped to a given filename
--- a difficult proposition, given that it is easy to produce
setups in which multiple URIs map to the same file).
*) Source files renamed and rearranged
*) Very simple pre-forking behavior --- parent process forked off a
fixed number of children, and then just waited for SIGHUP.
*) Other more minor changes too numerous to list.
This release included modified versions of a lot of code from the
Apache 0.6.4 public release, plus an early pre-forking patch
codeveloped by Robert Thau and Rob Hartill.
Changes with Apache 0.7.3 20 Jun 1995
*) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
were incorporated by Rob Hartill on the main branch while Robert Thau
worked on the Shambhala rewrite above. Most were merged into the
Shambala architecture after Apache 0.8.0.
Changes with Apache 0.6.4 13 May 1995
*) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
and others.
Changes with Apache 0.5.1 10 Apr 1995
Changes with Apache 0.4 02 Apr 1995
*) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
and Rob Hartill.
Changes with Apache 0.3 24 Mar 1995
*) Patches by Robert Thau, David Robinson, Rob Hartill, and
Carlos Varela.
Changes with Apache 0.2 18 Mar 1995
*) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
