Changes with Apache 2.0.63
*) winnt_mpm: Resolve modperl issues by redirecting console mode stdout
to /Device/Nul as the server is starting up, mirroring unix MPM's.
PR: 43534 [Tom Donovan <Tom.Donovan>, William Rowe]
*) winnt_mpm: Restore Win32DisableAcceptEx On directive and Win9x platform
by recreating the bucket allocator each time the trans pool is cleared.
PR: 11427 #16 (follow-on) [Tom Donovan <Tom.Donovan>]
Changes with Apache 2.0.62 (not released)
*) SECURITY: CVE-2007-6388 (
mod_status: Ensure refresh parameter is numeric to prevent
a possible XSS attack caused by redirecting to other URLs.
Reported by SecurityReason. [Mark Cox, Joe Orton]
*) SECURITY: CVE-2007-5000 (
mod_imagemap: Fix a cross-site scripting issue. Reported by JPCERT.
[Joe Orton]
*) Introduce the ProxyFtpDirCharset directive, allowing the administrator
to identify a default, or specific servers or paths which list their
contents in other-than ISO-8859-1 charset (e.g. utf-8). [Ruediger Pluem]
*) log.c: Ensure Win32 resurrects its lost robust logger processes.
[William Rowe]
*) mpm_winnt: Eliminate wait_for_many_objects. Allows the clean
shutdown of the server when the MaxClients is higher then 257,
in a more responsive manner [Mladen Turk, William Rowe]
*) Add explicit charset to the output of various modules to work around
possible cross-site scripting flaws affecting web browsers that do not
derive the response character set as required by RFC2616. One of these
reported by SecurityReason [Joe Orton]
*) http_protocol: Escape request method in 405 error reporting.
This has no security impact since the browser cannot be tricked
into sending arbitrary method strings. [Jeff Trawick]
*) http_protocol: Escape request method in 413 error reporting.
Determined to be not generally exploitable, but a flaw in any case.
PR 44014 [Victor Stinner <victor.stinner>]
Changes with Apache 2.0.61
*) SECURITY: CVE-2007-3847 (
mod_proxy: Prevent reading past the end of a buffer when parsing
date-related headers. PR 41144.
[Davi Arnaut, Nick Kew]

mod_cache: Prevent segmentation fault if a Cache-Control header has
no value. [Niklas Edmundsson <nikke>]
*) SECURITY: CVE-2006-5752 (
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 (
prefork, worker MPMs: Ensure that the parent process cannot
be forced to kill processes outside its process group.
[Joe Orton, Jim Jagielski]
*) mod_proxy_http: accept proxy-sendchunked/proxy-sendchunks as synonymous.
PR 43183 [Brian Rectanus <Brian.Rectanus>, Vincent Bray]
*) log core: ensure we use a special pool for stderr logging, so that
the stderr channel remains valid from the time plog is destroyed,
until the time the open_logs hook is called again. [William Rowe]
*) mod_ssl: Version reporting update; displays 'compiled against'
Apache and build-time SSL Library versions at loglevel [info],
while reporting the run-time SSL Library version in the server
info tags. Helps to identify a mod_ssl built against one flavor
of OpenSSL but running against another (also adds SSL-C version
number reporting.) [William Rowe]
*) mod_autoindex: Add in Type and Charset options to IndexOptions
directive. This allows the admin to explicitly set the
content-type and charset of the generated page and is therefore
a viable workaround for buggy browsers affected by CVE-2007-4465
( [Jim Jagielski]
*) main core: Emit errors during the initial apr_app_initialize()
or apr_pool_create() (when apr-based error reporting is not ready).
[William Rowe, Jeff Trawick]
*) log core: Fix issue which could cause piped loggers to be orphaned
and never terminate after a graceful restart. PR 40651. [Joe Orton,
Ruediger Pluem]
*) log core: fix the new piped logger case where we couldn't connect
the replacement stderr logger's stderr to the NULL stdout stream.
Continue in this case, since the previous alternative of no error
logging at all (/dev/null) is far worse. [William Rowe]
*) mpm_winnt: Prevent the parent-child pipe from leaking into other
spawned processes, and ensure we have a /Device/null handle for
stdout when running as-a-service. [William Rowe]
*) ApacheMonitor: Fix Windows Vista detection. [Mladen Turk]
*) mod_so: Solve dev's confusion by reporting expected/seen module
magic signatures when failing with a 'garbled' message, and solve
user's confusion by pointing out 'perhaps compiled for a different
version of apache?'. [William Rowe]
*) mod_ssl: initialize thread locks before initializing the hardware
acceleration library, so the latter can make use of the former.
PR 20951. [<adunn>]
*) mod_ssl: Support limited buffering of request bodies to allow
per-location renegotiation to proceed. PR 12355. [Joe Orton]
*) mod_cgi, mod_cgid: Don't return apr_status_t error value
from input filter chain. PR 31759 (mutated). [Jo Rhett,
Nick Kew]

the *_set params. PR 11540. [Jim Jagielski]
*) mod_isapi: Correctly present SERVER_PORT_SECURE.
PR 40573. [Matt Eaton <asf>]

support. Also corrects the slashes for Windows. PR 15993. [William Rowe]
*) mod_isapi: Handle "HTTP/1.1 200 OK" style status lines correctly, the
token parser worked while the resulting length was misinterpreted.
PR 29098. [Brock Bland <bbland>]
*) mod_isapi: Return 0 (failure) for more of the various ap_pass_brigade
attempts to stream the response at the client. Log these as well.
PR 30022, 40470. [William Rowe, Matt Eaton <asf>]
*) mod_isapi: Ensure we walk through all the methods the developer may have
employed to report their HTTP status result code.

run on Unix. [William Wrowe]
*) HTML-escape the Expect error message. Not classed as security as
an attacker has no way to influence the Expect header a victim will
send to a target site. Reported by Thiago Zaninotti
<thiango>. [Mark Cox]

*) SECURITY: CVE-2005-3357 (
mod_ssl: Fix a possible crash during access control checks if a
non-SSL request is processed for an SSL vhost (such as the
"HTTP request received on SSL port" error message when an 400
ErrorDocument is configured, or if using "SSLEngine optional").
PR 37791. [Rüdiger Plüm, Joe Orton]

ap_escape_html so we escape quotes. Reported by JPCERT.
[Mark Cox]
*) Add APR/APR-Util Compiled and Runtime Version numbers to the
output of 'httpd -V'. [William Rowe]

*) mod_proxy_http: Prevent data corruption of POST request bodies when
client accesses proxied resources with SSL. PR 37145.
[Ruediger Pluem, William Rowe]
*) Eliminated the NET_TIME filter, restructuring the timeout logic.
This provides a working mod_echo on all platforms, and ensures any
custom protocol module is at least given an initial timeout value
based on the <VirtualHost > context's Timeout directive.
[William Rowe]
*) mod_ssl: Correct issue where mod_ssl does not pick up the
ssl-unclean-shutdown setting when configured. PR 34452. [Joe Orton]
*) Document the ReceiveBufferSize change done in r157583.

the request includes a request body. Resolves an entire class of
proxy HTTP Request Splitting/Spoofing attacks. [William Rowe]
*) 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]
*) Add ap_log_cerror() for logging messages associated with particular
client connections. [Jeff Trawick]

and remove the noise on stderr during config dir processing.
[Joe Orton <jorton>]
*) mod_cache: cache_storage.c. Add the hostname and any request
args to the key generated for caching. This provides a unique
key for each virtual host and for each request with unique
args. [Paul J. Reder, args code provided by Kris Verbeeck]

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

than copying the file into the heap. [Brian Pane]
*) Modified version check on openssl so that it finds the executable
first and then performs a check of the version, only warning the
user if they chose, or we selected, an old version of OpenSSL.

*) SECURITY: CVE-2002-0661 (
Close a very significant security hole that
applies only to the Win32, OS2 and Netware platforms. Unix was not
affected, Cygwin may be affected. Certain URIs will bypass security
and allow users to invoke or access any file depending on the system
configuration. Without upgrading, a single .conf change will close
the vulnerability. Add the following directive in the global server
httpd.conf context before any other Alias or Redirect directives;
RedirectMatch 400 "\\\.\."
Reported by Auriemma Luigi <bugtest>.
[Brad Nicholes]
*) SECURITY: CVE-2002-0654 (
Close a path-revealing exposure in multiview type
map negotiation (such as the default error documents) where the
module would report the full path of the typemapped .var file when
multiple documents or no documents could be served based on the mime
negotiation. Reported by Auriemma Luigi <bugtest>.
[William Rowe]
*) SECURITY: CVE-2002-0654 (
Close a path-revealing exposure in cgi/cgid when we
fail to invoke a script. The modules would report "couldn't create
child process /path-to-script/" revealing the full path
of the script. Reported by Jim Race <jrace>.

*) Set aside the apr-iconv and apr_xlate() features for the Win32
build of 2.0.40 so development can be completed. A patch, from
will be available for those that wish to work with apr-iconv.
[William Rowe]
*) Fix proxy so that it is possible to access ftp: URLs via a proxy
chain. [Peter Van Biesen <peter.vanbiesen>]
*) mod-deflate now checks to make sure that 'gzip-only-text/html' is
set to 1, so we can exclude things from the general case with
browsermatch. [Ian Holsman, Andre Schild <A.Schild>]
*) Accept multiple leading /'s for requests within the DocumentRoot.
PR 10946 [William Rowe, David Shane Holden <dpejesh>]
*) Solved the reports of .pdf byterange failures on Win32 alone.
APR's sendfile for the win32 platform collapses header and trailer
buffers into a single buffer. However, we destroyed the pointers
to the header buffer if a trailer buffer was present. PR 10781

*) mod_ext_filter: Add the ability to enable or disable a filter via
an environment variable. Add the ability to register a filter of
type other than AP_FTYPE_RESOURCE. [Jeff Trawick]
*) Restore the ability to specify host names on Listen directives.

*) Replace usage of atol() to parse strings when we might want a
larger-than-long value with apr_atoll(), which returns long long.
This allows HTTPD to deal with larger files correctly.
[Shantonu Sen <ssen>]
*) mod_ext_filter: Ignore any content-type parameters when checking if
the response should be filtered. Previously, "intype=text/html"
wouldn't match something like "text/html;charset=8859_1".
[Jeff Trawick]
*) mod_ext_filter: Set up environment variables for external programs.
[Craig Sebenik <craig>]
*) Modified the HTTP_IN filter to immediately append the EOS (end of
stream) bucket for C-L POST bodies, saving a roundtrip and allowing
the caller to determine that no content remains without prefetching
additional POST body. [William Rowe]
*) Get proxy ftp to work over IPv6. [Shoichi Sakane <sakane>]
*) Look for OpenSSL libraries in /usr/lib64. [Peter Poeml <poeml>]
*) Update SuSE layout. [Peter Poeml <poeml>]
*) Changes to the internationalized error documents:
Comment them out in the default config file to make the default
install as simple as possible; Correct the english 500 error to
be more understandable; Add a Swedish translation.
[Thomas Sjogren <thomas>,
Erik Abele <erik>, Rich Bowen, Joshua Slive]
*) Increase the limit on file descriptors per process in apachectl.

[James Cox <imajes>]
*) mod_ext_filter: don't segfault if content-type is not set. PR 10617.
[Arthur P. Smith <apsmith>, Jeff Trawick]
*) APR-Util Renames pending have been completed [Thom May]
*) Performance improvements for the code that reads request
headers (ap_rgetline_core() and related functions) [Brian Pane]
*) Add a new directive: MaxMemFree. MaxMemFree makes it possible
to configure the maximum amount of memory the allocators will
hold on to for reuse. Anything over the MaxMemFree threshold
will be free()d. This directive is useful when uncommon large
peaks occur in memory usage. It should _not_ be used to mask
defective modules' memory use. [Sander Striker]
*) Fixed the Content-Length filter so that HTTP/1.0 requests to CGI
scripts would not result in a truncated response.
[Ryan Bloom, Justin Erenkrantz, Cliff Woolley]
*) Add a filter_init parameter to the filter registration functions
so that a filter can execute arbitrary code before the handlers
are invoked. This resolves a problem where mod_include requests
would incorrectly return a 304. [Justin Erenkrantz]
*) Fix a long-standing bug in 2.0, CGI scripts were being called
with relative paths instead of absolute paths. Apache 1.3 used
absolute paths for everything except for SuExec, this brings back
that standard. [Ryan Bloom]
*) Fix infinite loop due to two HTTP_IN filters being present for
internally redirected requests. PR 10146. [Justin Erenkrantz]
*) Switch conn_rec->keepalive to an enumeration rather than a bitfield.
[Justin Erenkrantz]
*) Fix mod_ext_filter to look in the main server for filter definitions
when running in a vhost if the filter definition is not found in
the vhost. PR 10147 [Jeff Trawick]
*) Support WinNT CGI invocation through ScriptInterpreterSource
'registry' for script interpreter paths and names with non-ascii
characters in the executable filepath. [William Rowe]
*) Support the -w flag on to keep the Win32 console open on error.
[William Rowe]
*) Normalize the hostname value in the request_rec to all-lowercase
[Perry Harrington <pedward>]
*) Fix WinNT cgi 500 errors when QUERY_ARGS or other strings include
extended characters (non US-ASCII) in non-utf8 format. This brings
Win32 back into CGI/1.1 compliance, and leaves charset decoding up
to the cgi application itself. [William Rowe]
*) Major overhaul of mod_dav, mod_dav_fs and the experimental/cache
modules to bring them up to the current apr/apr-util APIs.
[William Rowe]
*) Fix segfault in mod_mem_cache most frequently observed when
serving the same file to multiple clients on an MP machine.
[Bill Stoddard]
*) mod_rewrite can now set cookies (RewriteRule (.*) - [CO=name:$1:.domain])
[Brian Degenhardt <bmd>, Ian Holsman]
*) Fix perchild to work with apachectl by adding -k support to perchild.
PR 10074 [Jeff Trawick]
*) Fix a silly htpasswd.c logic error that incorrectly reported that
both -c and -n had been used. PR 9989 [Cliff Woolley]
*) Fixed a mod_include error case in which no HTTP response was sent
to the client if an shtml document contained an unterminated SSI
directive [Brian Pane]
*) Improve ap_get_client_block implementation by using APR-util brigade
helper functions and relying on current filter assumptions.
[Justin Erenkrantz]
Changes with Apache 2.0.39
*) Fixed a build problem in htpasswd.c on Win32.
[Guenter Knauf <eflash>, Cliff Woolley]
Changes with Apache 2.0.38
*) Rewrite htpasswd to use APR. The removes the annoying warning about
tmpnam being unsafe. [Ryan Bloom]
*) We must set the MIME-type for .shtml files to text/html if we want them
to be parsed for SSI tags. Add the config for that to the default
config file so that it is easier to enable .shtml parsing.
[Dave Dyer <ddyer>]
*) Fixed a problem with 'make install' on ReliantUnix.
[Jean-frederic Clere <jfrederic.clere>]
*) Make the default_handler catch all requests that aren't served by
another handler. This also gets us to return a 404 if a directory
is requested, there is no DirectoryIndex, and mod_autoindex isn't
loaded. [Justin Erenkrantz]
*) Fixed the handling of nested if-statements in shtml files.
PR 9866 [Brian Pane]
*) Allow 'make install DESTDIR=/path'. This allows packagers to install
into a directory different from the one that was configured. This
also mirrors the root= feature from 1.3. We cannot use prefix=,
because both APR and APR-util resolve their installation paths at
configuration time. This means that there is no variable prefix
to replace. [Andreas Hasenack <andreas>]
These levels of AIX don't have a thundering herd problem with
accept(). [Jeff Trawick]
*) prefork MPM: Ignore mutex errors during graceful restart. For
certain types of mutexes (particularly SysV semaphores), we
should expect to occasionally fail to obtain or release the
mutex during restart processing. [Jeff Trawick]
*) Fix so that it finds any perl instead of just
early perl 5.x versions. This is consistent with a build/install
from source, and it allows the perl scripts installed by a bindist
to work on systems with perl 5.6. [Jeff Trawick]
*) Fix apxs so that the makefile created by "apxs -g" works on AIX and
Tru64 (and probably some other platforms). [Jeff Trawick]
*) Allow CGI scripts to return their Content-Length. This also fixes a
hang on HEAD requests seen on certain platforms (such as FreeBSD).
[Justin Erenkrantz]
*) Added log rotation based on file size to the RotateLog support
utility. [Brad Nicholes]
*) Fix some casting in mod_rewrite which broke random maps.
PR 9770 [Allan Edwards, Greg Ames, Jeff Trawick]
Changes with Apache 2.0.37
*) allow POST method over SSL when per-directory client cert
authentication is used with 'SSLOptions +OptRenegotiate' enabled
and a client cert was found in the ssl session cache.
*) 'SSLOptions +OptRengotiate' will use client cert in from the ssl
session cache when there is no cert chain in the cache. prior to
the fix this situation would result in a FORBIDDEN response and
error message "Cannot find peer certificate chain"
[Doug MacEachern]
*) ap_finalize_sub_req_protocol() shouldn't send an EOS bucket if
one was already sent. PR 9644 [Jeff Trawick]
*) Fix the display of the default name for the mime types config
file. PR 9729 [Matthew Brecknell <mbrecknell>]
*) Fix the working directory *for WinNT/2K/XP services only* to
change to the Apache directory (one level above the location
of Apache.exe, in the case that Apache.exe resides in bin/.)
Solves the case of ServerRoot /foo paths where /foo was not
on the same drive as /winnt/system32. [William Rowe]

match how 1.3 does it. [Jim Jagielski]
*) Implement a fixed size memory cache using a priority queue
[Ian Holsman]
*) Fix apxs to allow "apxs -q installbuilddir" and to allow
querying certain other variables from PR 9316
[Jeff Trawick]
*) Added the "detached" attribute to the cgi_exec_info_t internals
so that Win32 and Netware won't create a new window or console
for each CGI invoked. PR 8387
[Brad Nicholes, William Rowe]
*) Consolidated the command line parameters and attributes that are
manipulated by the optional function ap_cgi_build_command() in
mod_cgi into a single structure.
[Brad Nicholes]
*) Get rid of uninitialized value errors with "apxs -q" on certain
variables. [Stas Bekman <stas>]
*) Fix apxs to allow it to work when the build directory is somewhere
besides server-root/build. PR 8453
[Jeff Trawick and a host of others]
*) Allow ap_discard_request_body to be called multiple times in the
same request. Essentially, ap_http_filter keeps track of whether
it has sent an EOS bucket up the stack, if so, it will only ever
send an EOS bucket for this request.
[Ryan Bloom, Justin Erenkrantz, Greg Stein]
*) Remove all special mod_ssl URIs. This also fixes the bug where
redirecting (.*) will allow an SSL protected page to be viewed
without SSL. [Ryan Bloom]
*) Fix the binary build install script so that the build logic
created by "apxs -g" will work when the user has a binary
build. [Jeff Trawick]
*) Allow to work with full paths to the shared module.
[Justin Erenkrantz]
*) NetWare: Enabled CGI functionality and added mod_cgi as a built
in module for NetWare [Brad Nicholes]
*) Changed cgi and piped log behavior to accept 65536 characters
on Win32 (matching Linux) before deadlocking between outputing
client stdin, slurping the output from stdout and then the stderr
stream. PR 8179 [William Rowe]
*) Fixed Win32 wintty.exe support to assure the window title is valid.
Elimiates possible gpfault or garbage title without the -t option.
[William Rowe]
*) Rewrite mod_cgi, mod_cgid, and mod_proxy input handling to use
brigades and input filters. [Justin Erenkrantz]
*) Allow ap_http_filter (HTTP_IN) to return EOS when there is no request
body. [Justin Erenkrantz]
*) NetWare: Piping log entries through RotateLogs using the
CustomLogs directive is finally supported now that we have
the pipes and spawning functionality working.
[Brad Nicholes]
*) SECURITY: CVE-2002-0392 ( [CERT VU#944335]
Detect overflow when reading the hex bytes forming a chunk line.
[Aaron Bannert]
*) Allow RewriteMap prg:'s to take command-line arguments. PR 8464.
[James Tait <JTait>]
*) Correctly return 413 when an invalid chunk size is given on
input. Also modify ap_discard_request_body to not do anything
on sub-requests or when the connection will be dropped.
[Justin Erenkrantz]
*) Fix the TIME_* SSL var lookups to be threadsafe. PR 9469.
[Cliff Woolley]
*) Ensure that apr_brigade_write() flushes in all of the cases that
it should to avoid conditions in some modules that could cause
large amounts of data to be buffered. [Cliff Woolley]
*) Fix problem where mod_cache/mod_disk_cache was incorrectly
stripping the content_type from cached responses.
[Bill Stoddard]
*) apachectl passes through any httpd options. Note: apachectl
should be used in preference to httpd since it ensures that any
appropriate environment variables have been set up.

*) Modify the module documentation to allow for translations.
[Yoshiki Hayashi, Joshua Slive]
*) Fix a file permissions problem which prevented mod_disk_cache
from working on Unix. [Jeff Trawick]
*) Add "-k start|restart|graceful|stop" support to httpd for the Unix
MPMs. These have semantics very similar to the old apachectl
commands of the same name. [Justin Erenkrantz, Jeff Trawick]
*) Make sure that the runtime dir is created by make install.

*) Remove SSLLog and SSLLogLevel directives in favor of having
mod_ssl use the standard ErrorLog directives. [Justin Erenkrantz]
*) OS/390: LIBPATH no longer has to be manually uncommented in
envvars to get apachectl to set up httpd properly. [Jeff Trawick]
*) mod_isapi: All mod_isapi directives, excluding ISAPICacheFile,
may now be specified to the <File/Directory > container, rather
than by vhost. [William Rowe]
*) mod_isapi: Experimental support for faux async support for ISAPI
modules. [William Rowe]
*) mod_isapi: Major refactoring of the code to rely on apr internals
rather than MS APIs (using our own mod_isapi.h headers for ISAPI
symbol definitions.) [William Rowe]
*) mod_isapi: Fixed the return string length from GetServerVariable

*) SECURITY: CVE-2002-1592 ( [CERT VU#165803]
Added the APLOG_TOCLIENT flag to ap_log_rerror() to
explicitly tell the server that warning messages should be sent
to the client in addition to being recorded in the error log.
Prior to this change, ap_log_rerror() always sent warning
messages to the client. In one case, a faulty CGI script caused
the server to send a warning message to the client that contained
the full path to the CGI script. This could be considered a
minor security exposure. [Bill Stoddard]
*) mod_autoindex output when SuppressRules was specified would
omit the first carriage return so the first item in the list
would appear to the right of the column headings instead of
underneath them. PR 8016 [David Shane Holden <dpejesh>]
*) Moved the call to apr_mmap_dup outside the error branch so
that it would actually get called. This fixes a core dump

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

that requirement. [Sander Striker]

Changes with Apache 2.0.32
*) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the

*) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
the service, mpm and logging code, and bugs in apr_file_open_stderr
and apr_file_dup2 functions. Win2K/XP services have no handles
associated for stdin/out/err, which caused unpredictable behavior
in the prior release. [William Rowe, Bill Stoddard]
*) Win32: simplify the Application Event Log messages, since there isn't
likely to be 'more information in the error log' before an error log

the original request used. [Ryan Bloom and Ken Coar]
*) In core_input_filter, check for an empty brigade after
APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
client says it will post some data but we get FIN before any

*) Not being able to bind to the socket is a fatal error. We should
print an error to the console, and return a non-zero status code.
With these changes, all of the Unix MPMs do that correctly.

*) apxs: LTFLAGS envvar can override default libtool options. Try
"LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under

*) 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]
Changes with Apache 2.0.31

*) Add a timeout option to the proxy code 'ProxyTimeout'
[Ian Holsman]
*) FTP directory listings are now always retrieved in ASCII mode.
The FTP proxy properly escapes URI's and HTML in the generated
listing, and escapes the path components when talking to the FTP
server. It is now possible to browse the root directory by using
a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
Also, the last path component may contain wildcard characters
'*' and '?', and if they do, a directory listing is created instead
of a file retrieval. Example: ftp://user@host/httpd/server/*.c
[Martin Kraemer]
*) Added single-listener unserialized accept support to the

*) Don't let the default handler try to serve a raw directory. At
best you get gibberish. Much worse things can happen depending
on the OS. [Jeff Trawick]
*) Change the pre_config hook to return a value. Modules can now emit
an error message and then cause the server to quit gracefully during
startup. This required a bump to the MMN. [Aaron Bannert]
*) Fix some unix socket descriptor leaks in the handler side of
mod_cgid (the part that runs in the server process). Whack a
silly "close(-1)" in the handler too. [Jeff Trawick]
*) Change the pre_mpm hook to return a value, so that scoreboard
init errors percolate up to code that knows how to exit
cleanly. This required a bump to the MMN. [Jeff Trawick]
*) Add the socket back to the conn_rec and remove the create_connection
hook. The create_connection hook had a design flaw that did not
allow creating connections based on vhost info. [Bill Stoddard]
*) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
Resolves the common case of using negotation to resolve the request
/script/foo for /script.cgi/foo. [William Rowe]
*) Added new functions ap_add_(input|output)_filter_handle to

[Jeff Trawick]
*) rewrite of mod_ssl input filter for better performance and less
memory usage [Doug MacEachern]
*) allow quick_handler to be run on subrequests. [Ian Holsman]
*) mod_dav now asks its provider to place content directly into the
filter stack when handling a GET request. The mod_dav/provider
API has changed, so providers need to be updated. [Greg Stein]
*) Clear the output socket descriptor in unixd_accept() to make sure
we don't supply a bogus socket to the caller if the accept fails.
This caused problems with the worker MPM, which tried to process
the returned socket if it was non-NULL. [Brian Pane]
*) Move a check for an empty brigade to the start of core input filter
to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
*) Add FileETag directive to allow configurable control of what
data are used to form ETag values for file-based URIs. MMN
bumped to 20020111 because of fields added to the end of
the core_dir_config structure. [Ken Coar]
*) Fix a segfault in mod_rewrite's logging code caused by passing the
wrong config to ap_get_remote_host(). [Jeff Trawick]
*) Allow mod_cgid to work from a binary distribution install by
using 755 for the permissions on the log directory instead of
750. [Jeff Trawick]
*) Fixed a segfault that happened during graceful shutdown (or when
the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
*) Split all Win32 modules [excluding the core components mod_core,
mod_so, mod_win32 and the winnt mpm] into individual loadable
modules, so the administrator may individually disable the former
compiled-in modules by simply commenting out their LoadModule
directives. [William Rowe]
*) Saved Win32 module authors and porters many future headaches, by
duplicating the appropriate .h files such as os.h into the include
directory, including in the build tree. [William Rowe]
*) mod_ssl adjustments to help with using toolkits other than OpenSSL:
Use SSL functions/macros instead of directly dereferencing SSL
structures wherever possible.
Add type-casts for the cases where functions return a generic pointer.
Add $SSL/include to configure search path.
[Madhusudan Mathihalli <madhusudan_mathihalli>]
*) Moved several pointers out of the shared Scoreboard so it is
more portable, and will present the vhost name across server
generation restarts. [William Rowe]
*) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
[Doug MacEachern]
Changes with Apache 2.0.30
*) Fix the main bug for FreeBSD and threaded MPM's. There are
still issues (see STATUS) but at least the server will now
run without crashing the machine.

*) Fix a typo in mod_deflate's m4 config section.
[albert chin <china>]
*) Fix a couple of mod_proxy problems forwarding HTTP connections
and handling CONNECT:
(1) PR #9190 Proxy failed to connect to IPv6 hosts.
(2) Proxy failed to connect when the first IP address returned by
the resolver was unreachable but a secondary IP address was.
[Jeff Trawick]

modules (e.g., the identifer for mod_log_config was previously
listed as config_log_module). PR #9338

*) Fix LimitRequestBody directive by placing it in the HTTP
filter. [Justin Erenkrantz]
*) Fix mod_proxy seg fault when the proxied server returns
an HTTP/0.9 response or a bogus status line.
[Adam Sussman]
*) Prevent mod_proxy from truncating one character off the
end of the status line returned from the proxied server.
[Adam Sussman, Bill Stoddard]
*) Eliminate loop in ap_proxy_string_read().
[Adam Sussman, Bill Stoddard]
*) Provide $0..$9 results from mod_include regex parsing.
[William Rowe]
*) Allow mod-include to look for alternate start & end tags [Ian Holsman]
*) Introduced the ForceLanguagePriority directive, to prevent
returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
when using Multiviews. [William Rowe]
*) Fix a problem which prevented mod_cgid and suexec from working
together reliably [Greg Ames]
*) Remove the call to exit() from within mod_auth_digest's post_config
phase. [Aaron Bannert]
*) Fix a problem in mod_auth_digest that could potentially cause
problems with initialized static data on a system that uses DSOs.
[Aaron Bannert]
*) Fix a segfault in the worker MPM that could happen during
child process exits. [Brian Pane, Aaron Bannert]
*) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
*) Fix matching of vhosts by ip address so we find IPv4
vhost address when target address is v4-mapped form of
that address. [Jeff Trawick]
*) More performance tweaks to the BNDM string-search algorithm
used to find "<!--#" tokens in mod_include [Brian Pane]
*) Miscellaneous small performance fixes: optimized away various
string copy operations and removed large temp buffers from
the stack [Brian Pane]
*) Fixed startup segfault that occurred when a VirtualHost
directive had a port but no address [Brian Pane]
*) Allow htdbm to work with multiple DBM types [Ian Holsman]
*) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
if oslevel < WINNT. This should fix several problems reported
Against 2.0.28 on Windows 98 [Bill Stoddard]
*) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
to fail. [Bill Stoddard]
*) Change core code to allow an MPM to set hard thread/server
limits at startup. prefork, worker, and perchild MPMs now have
directives to set these limits. [Jeff Trawick]
*) Win32: The async AcceptEx() event should be autoreset upon
successful completion of a wait (WaitForSingleObject). This
eliminates a number of spurious
setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
[Bill Stoddard]
*) Move any load library path environment variables out of
apachectl and into a separate environment variable file which
can be more easily tailored by the admin. The environment
variable file as built by Apache may have additional system-
specific settings. For example, on OS/390 we tailor the heap
settings to allow lots of threads. [Jeff Trawick]
*) Use the new APR pool code to reduce pool-related lock
contention in the worker MPM. [Sander Striker]
*) The POD no longer assumes the child is listening on
and now pulls the first hostname in the list of listeners to
perform the dummy connect on. This fixes a bug when the user
had configured the Listen directive for an IP other than This would result in undead children and error
messages such as "Connection refused: connect to listener".
[Aaron Bannert]
*) The worker MPM now respects the LockFile setting, needed to
avoid locking problems with NFS. [Jeff Trawick]
*) Fix segfault when worker MPM receives SIGHUP.
[Ian Holsman, Aaron Bannert, Justin Erenkrantz]
*) Fix bug that could potentially prevent the perchild MPM from
working with more than one vhost/uid. [Aaron Bannert]
*) Change make install and apxs -i processing of DSO modules to
perform special handling on platforms where libtool doesn't install This fixes some wonkiness on HP-UX, Tru64, and AIX
which prevented standard LoadModule statements from working.
[Jeff Trawick]
*) Whenever mod_so is enabled (not just when there are DSOs for
our modules), do whatever special magic is required for compiling/
loading third-party modules. This allows third-party DSOs to
be used on an AIX build when there were no built-in modules
built as DSOs. (This should help on OS/390 and BeOS as well.)
[Jeff Trawick]
*) Allow apxs to be used to build DSOs on AIX without requiring the
user to hard-code the list of import files. (This should help
on OS/390 and BeOS as well.) [Jeff Trawick]
*) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
PR 8563, 8919 [William Rowe]
*) Get binary builds working when libapr and libaprutil are built

terminating "-->" is the last byte in a file [Brian Pane]
*) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
message that we had back in apache-1.3 and still have scattered
throughout our docs. [Aaron Bannert]

lists of small buckets don't cause small packet writes.
[Brian Pane, Ryan Bloom]
*) Fix the installation target to make sure that the manual is
installed in the correct location.
[Yoshifumi Hiramatsu <hiramatu> and
Gomez Henri <hgomez>]
*) Fix the cmd command for mod_include. When we are processing
a cmd command, we do not want to use the r->filename to set
the command name. The command comes from the SSI tag. To do this,
I added a variable to the function that builds the command line
in mod_cgi. This allows the include_cmd function to specify
the command line itself. [Ryan Bloom]
*) Change open_logs hook to return a value, allowing you
to flag a error while opening logs
[Ian Holsman, Doug MacEachern]
*) Change post_config hook to return a value, allowing you
to flag a error post config
[Ian Holsman, Jeff Trawick]
*) Allow SUEXEC_BIN (the path to the suexec binary that is
hard-coded into the server) to be specified to the configure
script by the --with-suexec-bin parameter. [Aaron Bannert]

[Taketo Kabe <kabe>, Cliff Woolley] PR#8804
*) The threaded MPM for Unix has been removed. Use the worker
MPM instead. [various]
*) APR-ize the resolver logic in mod_unique_id. This fixes a bug
in logging the error from a failed DNS lookup. [Jeff Trawick]
*) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
[Cliff Woolley]
*) Get mod_cgid killed when a MPM exits due to a fatal error.
[Jeff Trawick]
*) Fix a file descriptor leak in mod_include. When we include a
file, we use a sub-request, but we didn't destroy the sub-request
immediately, instead we waited until the original request was
done. This patch closes the sub-request as soon as the data is
done being generated. [Brian Pane <bpane>]
*) Allow modules that add sockets to the ap_listeners list to
define the function that should be used to accept on that
socket. Each MPM can define their own function to use for
the accept function with the MPM_ACCEPT_FUNC macro. This
also abstracts out all of the Unix accept error handling
logic, which has become out of synch across Unix MPMs.
[Ryan Bloom]
*) Fix a bug which would cause the response headers to be omitted
when sending a negotiated ErrorDocument because the required
filters were attached to the wrong request_rec.
[John Sterling <sterling>]
*) Remove commas from the end of the macros that define
directives that are used by MPMs. Prior to this patch,
you would use these macros without commas, which was unlike
the macros for any other directives. Now, the caller provides
the comma rather than the macro providing it. This makes
the macros look more like the rest of the directives.
[Ryan Bloom and Cliff Woolley]
*) Add 'redirect-carefully' environment option to disable sending
redirects under special circumstances. This is helpful for
Microsoft's WebFolders when accessing a directory resource via
DAV methods. [Justin Erenkrantz]
*) Begin to abstract out the underlying transport layer.
The first step is to remove the socket from the conn_rec,
the server now lives in a context that is passed to the
core's input and output filters. This forces us to be very
careful when adding calls that use the socket directly,
because the socket isn't available in most locations.
[Ryan Bloom]
*) Really reset the MaxClients value in worker and threaded
when the configured value is not a multiple of the number
of threads per child. We said we did previously but we
forgot to. [Jeff Trawick]
*) Add Debian layout. [Daniel Stone <daniel>]
*) If shared modules are requested and mod_so is not available,
produce a fatal config-time error. [Justin Erenkrantz]
*) Improve http2env's performance by cutting the work it has to
do. [Brian Pane <bpane>]

[Brian Pane <bpane>]
Changes with Apache 2.0.28
*) Fix infinite loop in mod_cgid.c.
[Dale Ghent <daleg>, Brian Pane <bpane>]
*) When no port is given in a "ServerName host" directive, the
server_rec->port is now set to zero, not 80. That allows for
run-time deduction of the correct server port (depending on
SSL/plain, and depending also on the current setting of
UseCanonicalName). This change makes redirections
work, even with https:// connections. As in Apache-1.3, the
connection's actual port number is never used, only the ServerName
setting or the client's Host: setting. Documentation updated
to reflect the change. [Martin Kraemer]
*) Add a '%{note-name}e' argument to mod-headers, which works in
the same way as mod_log_confg. [Ian Holsman]
*) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
MPMs. [Cliff Woolley]
*) Introduce htdbm, a user management utility for db/dbm authorization
databases. [Mladen Turk <mturk>]
*) Optimize usage of strlen and strcat in ap_directory_walk.
[Brian Pane <bpane>]
Changes with Apache 2.0.27
*) Introduce an Apache mod_ssl initial configuration template
(ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
*) Fixed a memory leak in the getline parsing code that could
be triggered by arbitrarily large header lines. Requests
from the core input filter for single lines are now limited
to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
*) Fix a truncation bug in how we print the port on the Via: header.
The routine that prints the Via: header now takes a length for
the port string. [Zvi Har'El <rl>]
*) 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. [Jeff Trawick]
*) Add the support/checkgid helper app, which checks the run-time
validity of group identifiers usable in the Group directive.
[Ken Coar]
*) Various --enable-so options have been fixed: --enable-so is
treated as "static"; explicit --enable-so=shared issues an error;
and explicit --enable-so fails with error on systems without
APR_HAS_DSO. [Aaron Bannert]
*) Fix a segfault in the core input filter when the client socket
gets disconnected unexpectedly. [Cliff Woolley]
*) Fix the reporting for child processes that die. This removes
all of the non-portable W* macros from Apache.
[Jeff Trawick and Ryan Bloom]
*) Win32: Track and display "Parent Server Generation:" in
mod_status output. The generation will be bumped at
server graceful restart, when the child process exits
by hitting MaxRequestsPerChild or if the child
process exits abnormally. [Bill Stoddard]
*) Win32: Fix problem where MaxRequestsPerChild directive was
not being picked up in favor of the default. Enable
the parent to start up a new child process immediately upon
the old child starting shutdown.
[Bill Stoddard]
*) Fix some bungling of the remote port in rfc1413.c so that
IdentityCheck retrieves the proper user id instead of failing
and thus always returning "nobody."
[Dick Streefland <Dick.Streefland>]
*) Introduced thread saftey for mod_rewrite's internal cache.
[Brian Pane <bpane>]
*) Simplified mod_env's directives to behave as most directives are
expected, in that UnsetEnv will not unset a SetEnv and PassEnv
directive following that UnsetEnv within the same container.
Also provides a runtime startup warning if a PassEnv configured
environment value is undefined. [William Rowe]
*) The worker MPM is now completely ported to APR's new lock API. It
uses native APR types for thread mutexes, cross-process mutexes,
and condition variables. [Aaron Bannert]
*) Sync up documentation to remove all references to the now deprecated
Port directive. [Justin Erenkrantz]
*) Moved all ldap modules from the core to httpd-ldap sub-project
[Ryan Bloom]
*) Exit when we can't listen on any of the configured ports. This
is the same behavior as 1.3, and it avoids having the MPMs to
deal with bogus ap_listen_rec structures. [Jeff Trawick]
*) Cleanup the proxy code that creates a request to the origin
server. This change adds an optional hook, which allows modules
to gain control while the request is created if the proxy module
is loaded. The purpose of this hook is to allow modules to add
input and/or output filters to the request to the origin. While
I was at it, I made the core use this hook, so that proxy request
creation uses some of the code from the core. This can still be
greatly improved, but this is a good start. [Ryan Bloom]
Changes with Apache 2.0.26
*) Port the MaxClients changes from the worker MPM to the threaded
MPM. [Ryan Bloom]
*) Fix mod_proxy so that it handles chunked transfer-encoding and works
with the new input filtering system. [Justin Erenkrantz]
*) Introduce the MultiviewsMatch directive, to allow the operator
to be flexible in recognizing Handlers and Filters filename
extensions as part of the Multiviews matching logic, strict with
MultiviewsMatch NegotiatedOnly to accept only filename extentions
that designate negotiated parameters, (content type, charset, etc.)
or MultiviewsAll for the 1.3 behavior of matching any files, even
if they have unregistered extensions. [William Rowe]
*) Fixed the configure script to add a LoadModule directive to
the default httpd.conf for any module that was compiled
as a DSO. [Aaron Bannert <aaron>]
*) rewrite mod_ssl input filtering to work with the new input filtering
system. [Justin Erenkrantz]
*) prefork: Don't segfault when we are able to listen on some but
not all of the configured ports. [Jeff Trawick]
*) Build mod_so even if no core modules are built shared.
[Aaron Bannert <aaron>]
*) Introduce ap_directory_walk rewrite (with further optimizations
required) to adapt to the ap_process_request_internal() changes.
Optimized so subrequests and redirects now reuse previous section
merges, until we mismatch with the original directory_walk, and
precomputed r->finfo results will cause directory_walk to skip
the most expensive phases of the function. [William Rowe]
*) Allow ApacheMonitor to connect to and control Apache on other
WinNT/2K machines. [Mladen Turk <mturk>]
*) Remove the Port directive. In it's place, the Listen directive
is now a required directive, which tells Apache what port to
listen on. The ServerName directive has also been extended
to accept an optional port. If the port is specified to the
ServerName, the server will report that port whenever it
reports the port that it is listening on. This change was
made to ease configuration errors that stem from having a Port
directive, and a Listen directive. In that situation, the server
would only listen to the port specified by the Listen command,
which caused a lot of confusion to users. [Ryan Bloom]
*) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
build, as loadable modules. [William Rowe]
*) Fix --enable-mods-shared processing. If most is specified,
then all modules that can be compiled as shared modules are.
[Aaron Bannert <aaron>]
*) 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>, Lars Eilebrecht]
*) Eliminate the depreciated r->content_language, in favor of the array
r->content_languages introduced many years ago. Module authors must
substantially overhaul their modules, so this needs to be upgraded
if the module still relied on backwards-brokeness. [William Rowe]
*) Allow configure help strings to work with autoconf 2.50+ and 2.13.
[Justin Erenkrantz]
*) Rewrite the input filtering mechanisms to consolidate and reorganize
code. In short, core_input_filter does something now and
ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
*) Update the Win32 build to re-absorb mod_proxy and family.
[William Rowe]
*) Resolved the build failure on Win32 using MSVC 5.0 (without the
current SDK.) [William Rowe]
*) Some style changes to the code that does ProxyErrorOverride. Fixed
config merge behaviour. [Graham Leggett]
*) Allow support programs to be compiled against a static version
of libapr. This allows the smaller support programs to be
relocated. [Aaron Bannert <aaron>]
*) Update the mime.types file to the registered media types as
of 2001-09-25, and add mapping for xsl extension [Mark Cox]
*) Fix MaxClients in the Worker MPM, so that it specifies the maximum
number of clients that can connect at the same time, instead of
specifying the maximum number of child processes.
[Aaron Bannert <aaron>]
*) Switch proc_pthread AcceptMutex configuration directive to pthread to
be consistent with 1.3. [Justin Erenkrantz]
*) Cache apr_explode_localtime() value for 15 seconds.
[Brian Pane <bpane>]
*) Fix mod_include to not return ETag or Last-Modified headers.
[Ian Holsman <ianh>]
*) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron>]
*) Eliminate the wasteful run-time conversion of method names from strings
to numbers in places where the methods are known at compile time.
[Brian Pane <bp
