Changes with Apache 2.0.41
*) Allow AddOutputFilterByType to add multiple filters per directive.
[Justin Erenkrantz]
*) Remove warnings with Sun's Forte compiler. [Justin Erenkrantz]
*) Fixed mod_disk_cache's generation of 304s
[Kris Verbeeck <Kris.Verbeeck@ubizen.com>]
*) Add support for using fnmatch patterns in the final path
segment of an Include statement (eg.. include /foo/bar/*.conf).
and remove the noise on stderr during config dir processing.
[Joe Orton <jorton@redhat.com>]
*) 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]
*) mod_cache: Do not cache responses to GET requests with query
URLs if the origin server does not explicitly provide an
Expires header on the response (RFC 2616 Section 13.9)
[Kris Verbeeck krisv@be.ubizen.com]
*) Fix memory leak in core_output_filter. [Justin Erenkrantz]
*) Rewrite of aaa modules to an authn/authz model.
[Dirk-Willem van Gulik, Justin Erenkrantz]
*) Update OpenSSL detection to work on Darwin.
[Sander Temme <sctemme@covalent.net>]
*) Update the xslt and css to give the documentation a more
modern style.
[André Malo <nd@perlig.de>, Gernot Winkler <greh@o3media.de>]
*) Fix some bucket memory leaks in the chunking code
[Joe Schaefer <joe+apache@sunstarsys.com>]
*) Add ModMimeUsePathInfo directive. [Justin Erenkrantz]
*) mod_cache: added support for caching streamed responses (proxy,
CGI, etc) with optional CacheMaxStreamingBuffer setting [Brian Pane]
*) Add image/x-icon to httpd.conf PR 10993.
[Ian Holsman, Peter Bieringer <pb@bieringer.de>]
*) Fix FileETags none operation. PR 12207.
[Justin Erenkrantz, Andrew Ho <andrew@tellme.com>]
*) Restored the experimental leader/followers MPM to working
condition and converted its thread synchronization from
mutexes to atomic CAS. [Brian Pane]
*) Fix Logic on non-html file removal in mod_deflate
[Kris Verbeeck <Kris.Verbeeck@ubizen.com>]
*) Fix "ab -g"'s truncated year: the last digit was cut off.
[Leon Brocard <acme@astray.com>]
*) mod_rewrite can now sets cookies in err_headers, uses the correct
expiry date, and can now set the path as well
PR 12132,12181,12172.
[Ian Holsman / Rob Cromwell <apachechangelog@robcromwell.com>]
*) 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.
[Bill Stoddard]
*) Win32: Implement ThreadLimit directive in the Windows MPM.
[Bill Stoddard]
*) Remove CacheOn config directive since it is set but never checked.
No sense wasting cycles on unused code. Besides, the only truly
bug free code is deleted code. :) [Paul J. Reder]
*) BufferLogs are now run-time enabled, and the log_config now has 2 new
callbacks to allow a 3rd party module to actually do the writing of the
log file [Ian Holsman]
*) Correct ISAPIReadAheadBuffer to default to 49152, per mod_isapi docs.
[André Malo, Astrid Keßler <kess@kess-net.de>]
*) Fix Segfault in mod_cache. [Kris Verbeeck <Kris.Verbeeck@ubizen.com>]
*) Fix a null pointer dereference in the merge_env_dir_configs
function of the mod_env module. PR 11791
[Paul J. Reder]
*) New option to ServerTokens 'maj[or]'. Only show the major version
Also Surfaced this directive in the standard config (default FULL)
[Ian Holsman]
*) Change mod_rewrite to use apr-util's dbm support for dbm rewrite
maps. The dbm type (e.g., ndbm, gdbm) can be specified on the
RewriteMap directive. PR 10644 [Jeff Trawick]
*) Fixed mod_rewrite's RewriteMap prg: support so that request/response
pairs will no longer get out of sync with each other. PR 9534
[Cliff Woolley]
*) Fixes required to get quoted and escaped command args working in
mod_ext_filter. PR 11793 [Paul J. Reder]
*) mod-proxy: handle proxied responses with no status lines
[JD Silvester <jsilves@uwo.ca>, Brett Huttley <brett@huttley.net>]
*) Fix bug where environment or command line arguments containing
non-ASCII-7 characters would cause the Win32 child process creation
to fail. PR 11854 [William Rowe]
*) Bug #11213.. make module loading error messages more informative
[Ian Darwin <Ian779@darwinsys.com>]
*) thread safety & proxy-ftp [Alexey Panchenko alexey@liwest.ru, Ian Holsman]
*) mod_disk_cache works much better. This module should still
be considered experimental. [Eric Prud'hommeaux]
*) Performance improvement for keepalive requests: when setting
aside a small file for potential concatenation with the next
response on the connection, set aside the file descriptor rather
than copying the file into the heap. [Brian Pane]
Changes with Apache 2.0.40
*) SECURITY: [CAN-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@sitoverde.com>.
[Brad Nicholes]
*) SECURITY: 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@sitoverde.com>.
[CAN-2002-0654] [William Rowe]
*) SECURITY: 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/script.pl" revealing the full path
of the script. Reported by Jim Race <jrace@qualys.com>.
[CAN-2002-0654] [Bill Stoddard]
*) 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
<http://www.apache.org/dist/httpd/patches/apply_to_2.0.40/>
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@vlafo.be>]
*) 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@aarboard.ch>]
*) Accept multiple leading /'s for requests within the DocumentRoot.
PR 10946 [William Rowe, David Shane Holden <dpejesh@yahoo.com>]
*) 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
[William Rowe]
*) mod_ext_filter: Add the ability to enable or disable a filter via
an environment variable. Add the ability to register a filter of

*) When deciding on the default address family for listening sockets,
make sure we can actually bind to an AF_INET6 socket before
deciding that we should default to AF_INET6. This fixes a startup
problem on certain levels of OpenUNIX. PR 10235. [Jeff Trawick]
*) 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@apple.com>]
*) 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".

*) mod_ext_filter: Set up environment variables for external programs.
[Craig Sebenik <craig@netapp.com>]
*) Modified the HTTP_IN filter to immediately append the EOS (end of

*) 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.

[Perry Harrington <pedward@webcom.com>]
*) 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

*) 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@real-me.net>]
*) Fixed a problem with 'make install' on ReliantUnix.
[Jean-frederic Clere <jfrederic.clere@fujitsu-siemens.com>]
*) 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@netbank.com.br>]
*) AIX 4.3.2 and above: Define SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
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 install-bindist.sh 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.

Changes with Apache 2.0.37
*) allow POST method over SSL when per-directory client cert
authentication is used with 'SSLOptions +OptRenegotiate' enabled

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

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]

and completely contained in a file (SCOREBOARD_FILE) has been
removed. This does not affect scoreboards which are *mapped* to
files using named-shared-memory. [Jim Jagielski]
*) Change bucket brigades API to allow a "bucket allocator" to be
passed in at certain points. This allows us to implement freelists
so that we can stop using malloc/free so frequently.
[Cliff Woolley, Brian Pane]
*) Add support for macro expansion within the variable names in
<!--#echo--> and <!--#set--> directives [Brian Pane]
*) Fix some mod_include segfaults [Cliff Woolley, Brian Pane, Brad Nicholes]
*) Update the "RedHat" Layout to match Red Hat Linux version 7. PR BZ-7422
[Joe Orton]
*) add compat layer to support RSA SSLC 1.x and 2.x in mod_ssl
[Jon Travis, John Barbee, William Rowe, Ryan Bloom, Doug MacEachern]
*) Add a new parameter to the quick_handler hook to instruct
quick handlers to optionally do a lookup rather than actually
serve content. This is the first of several changes required fix
several problems with how quick handlers work with subrequests.
[Bill Stoddard]
*) worker MPM: Get MaxRequestsPerChild to work again. [Jeff Trawick]
*) [APR-related] The ordering of the default accept mutex method has
been changed to better match what's done in Apache 1.3. The ordering
is now (highest to lowest): pthread -> sysvsem -> fcntl -> flock.
[Jim Jagielski]
*) Ensure that the build/ directory is created when using VPATH.
[Justin Erenkrantz]
*) Add some popular types to the mime magic file. PR 7730.
[Linus Walleij <triad@df.lth.se>, Justin Erenkrantz]
*) Remove the single-byte socket reads for CGI headers [Brian Pane]
*) 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]
*) Fix a mod_cgid problem that left daemon processes stranded
in some server restart scenarios. [Jeff Trawick]
*) Added exp_foo and rel_foo variables to config_vars.mk for
all Apache and Autoconf path variables (like --sysconfdir,
--sbindir, etc). exp_foo is the "expanded" version, which means
that all internal variable references have been interpolated.
rel_foo is the same as $exp_foo, only relative to $prefix if they
share a common path. [Aaron Bannert]
*) Fix some restart/terminate problems in the worker MPM. Don't
drop connections during graceful restart. [Jeff Trawick]
*) Change the header merging behaviour in proxy, as some headers
(like Set-Cookie) cannot be unmerged due to stray commas in
dates. [Graham Leggett]
*) Be more vocal about what AcceptMutex values we allow, to make
us closer to how 1.3 does it. [Jim Jagielski]
*) Get nph- CGI scripts working again. PRs 8902, 8907, 9983
[Jeff Trawick]
*) Upgraded PCRE library to latest version 3.9 [Brian Pane]
*) Add accessor function to set r->content_type. From now on,
ap_rset_content_type() should be used to set r->content_type.
This change is required to properly implement the
AddOutputFilterByType configuration directive.
[Bill Stoddard, Sander Striker, Ryan Bloom]
*) Add new M_FOO symbols for the WebDAV/DeltaV methods specified by
RFC 3253. Improved the method name/number mapping functions.
[Greg Stein]
*) remove sock_enable_linger from connection.c [Ian Holsman]
*) Fix for virtual host processing where the requested hostname
has a '.' at the end (PR 9187) [Ryan Cruse <ryan@estara.com>]
*) mod_dav's APIs for REPORT response handling was changed so that
providers can generate the content directly into the output filter
stack, rather than buffering the response into memory. [Greg Stein]
*) Fix a hang condition with graceful restart and prefork MPM
in the situation where MaxClients is very high but
much fewer servers are actually started at the time of the
restart. [Jeff Trawick]
*) Small performance fixes for mod_include [Brian Pane]
*) Performance improvement for the error logger [Brian Pane]
*) Change configure so that Solaris 8 and above have
SINGLE_LISTEN_UNSERIALIZED_ACCEPT defined by default.
according to sun people solaris 8+ doesn't have a thundering
herd problem [Ian Holsman]
*) Allow URIs specifying CGI scripts to include '/' at the end
(e.g., /cgi-bin/printenv/) on AIX and Solaris (and other OSs
