Changes in Apache 2.3.0 async-dev R&D branch
*) Added asynchronous write completion for Event MPM. [Brian Pane]
*) For asynchronous MPMs, moved responsibility for write completion from
the core to the MPM. [Brian Pane]
*) Added an End-Of-Request bucket type. The logging of a request and
the freeing of its pool are now done when the EOR bucket is destroyed.
This has the effect of delaying the logging until right after the last
of the response is sent; ap_core_output_filter() calls the access logger
indirectly when it destroys the EOR bucket. [Brian Pane]
*) Rewrite of ap_core_output_filter to do nonblocking writes [Brian Pane]
*) Added new connection states for handler and write completion
[Brian Pane]

invoked cgi application, to conform to the behavior of mod_cgi.
[Pradeep Kumar S <pradeep.smani>]
*) Doxygen fixup [Neale Ranns <neale>, Ian Holsman]

allowing string-valued client certificate attributes to be used for
access control, as in: SSLRequire "value" in OID("")
[Martin Kraemer, David Reid]
Changes with Apache 2.1.7
*) SECURITY: CAN-2005-2491 (
Fix integer overflows in PCRE in quantifier parsing which could
be triggered by a local user through use of a carefully-crafted
regex in an .htaccess file. [Philip Hazel]
*) mod_proxy/mod_proxy_balancer: Provide a simple, functional
interface to add additional balancer lb selection methods
without requiring code changes to mod_proxy/mod_proxy_balancer;
these can be implemented via sub-modules now. [Jim Jagielski]
*) mod_cache: Fix incorrectly served 304 responses when expired cache
entity is valid, but cache is unwritable and headers cannot be
updated. [Colm MacCarthaigh <colm>]
*) mod_cache: Remove entities from the cache when re-validation
receives a 404 or other content-no-longer-present error.
[Rüdiger Plüm ruediger.pluem]

based on the proxy status. (minor MMN bump)
[Brian Akins <bakins>, Ian Holsman]
*) SECURITY: CAN-2005-2088
proxy: Correctly handle the Transfer-Encoding and Content-Length
headers. Discard the request Content-Length whenever T-E: chunked
is used, always passing one of either C-L or T-E: chunked whenever
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 additional SSLSessionCache option, 'nonenotnull', which is
similar to 'none' (disabling any external shared cache) but forces
OpenSSL to provide a non-null session ID. [Jim Jagielski]

many features and many directives that are at their default
setting. Add a selection of example config excerpts for adding
extra features in the conf/extra/ directory. Install the
distributed config and the extra config examples in the
conf/original/ directory during make install.
[Joshua Slive, Justin Erenkrantz]
*) NetWare: Reposition mod_asis, mod_actions, mod_cgi, mod_imagemap,

take advantage of LDAP authorization only [PR 28253]
[Jari Ahonen jah, Brad Nicholes]
*) Log the client IP address when an error occurs disabling nagle on a
connection, but log at a severity of debug since this error
generally means that the connection was dropped before data was

[Jan Kratochvil <>]
*) Restructured mod_auth_ldap to fit the new authentication model.
The module is now called authnz_ldap and has been moved out of
the modules/experimental area and into modules/aaa with the other
auth modules. Both the authn_ldap provider and the authz_ldap
handler are contained within the authnz_ldap module. The

across mod_auth_ldap and mod_ldap. Also added LDAPTrustedCA
and LDAPTrustedCAType directives to mod_ldap to allow for a more
common method of specifying the SSL certificate.
[Dave Ward, Brad Nicholes]

configuration file was not closed. PR 17093. [André Malo]
*) Enhance the behavior of mod_isapi's WriteClient() callback to
provide better emulation for isapi modules that presume that the
first WriteClient() call may send status and headers. An example
of WriteClient() abuse is the foxisapi module, which relies on
that assumpion and now works. [William Rowe, Milan Kosina]
*) Check the return value of ap_run_pre_connection(). So if the
pre_connection phase fails (without setting c->aborted)
ap_run_process_connection is not executed. [Stas Bekman]
*) Fixed a problem with mod_ldap which caused it to fault when caching
was disabled. Needed to make sure that the code did not
attempt to use the cache if it didn't exist. Also fixed some memory
leaks which were due to not releasing LDAP resources on error
conditions. [Brad Nicholes]

mod_rewrite proxied URLs will not be escaped accidentally by
mod_proxy's fixup. PR 16368 [André Malo]

restart a piped log program in more failure situations. Fix an
existing problem with error handling in piped_log_spawn(). Use
new APR apr_proc_create() features to prevent Apache from starting

*) apxs: Include any special APR ld flags when linking the DSO.
This resolves problems on AIX when building a DSO with apxs+gcc.
[Jeff Trawick]
*) Added character set support to mod_auth_LDAP to allow it to
convert extended characters used in the user ID to UTF-8
before authenticating against the LDAP directory. The new
directive AuthLDAPCharsetConfig is used to specify the config
file that contains the character set conversion table.

*) Reorder the definitions for mod_ldap and mod_auth_ldap within
config.m4 to make sure the parent mod_ldap is defined first.
This ensures that mod_ldap comes before mod_auth_ldap in the
httpd.conf file, which is necessary for mod_auth_ldap to load.
PR 14256 [Graham Leggett]
*) Fix the building of cgi command lines when the query string
contains '='. PR 13914 [Ville Skyttä <ville.skytta>,
Jeff Trawick]
*) Rename CacheMaxStreamingBuffer to MCacheMaxStreamingBuffer. Move
implementation of MCacheMaxStreamingBuffer from mod_cache to
mod_mem_cache. MCacheMaxStreamingBuffer now defaults to the
lesser of 100,000 bytes or MCacheMaxCacheObjectSize. This should
eliminate the need for explicitly coding MCacheMaxStreamingBuffer
in most configurations. [Bill Stoddard]
*) mod_cache: Fix PR 15113, a core dump in cache_in_filter when
a redirect occurs. The code was passing a format string and
integer to apr_pstrcat. Changed to apr_psprintf.

pages.) [André Malo <nd>]
*) mod_log_config: Allow '%%' escaping in CustomLog format
strings to insert a literal, single '%'.
[André Malo <nd>]
*) mod_autoindex: AddDescription directives for directories
now work as in Apache 1.3, where no trailing '/' is
specified on the directory name. Previously, the trailing
'/' *had* to be specified, which was incompatible with
Apache 1.3. PR 7990 [Jeff Trawick]
*) Fix for PR 14556. The expiry calculations in mod_cache were
trying to perform "now + ((date - lastmod) * factor)" where
date == lastmod resulting in "now + 0". The code now follows
the else path (using the default expiration) if date is
equal to lastmod. [Sergey <rx>, Paul J. Reder]

IPv6 listening sockets. PR 14037 (Bugzilla), PR 7492 (Gnats)
[Jeff Trawick]
*) This fixes a problem where the underlying cache code
indicated that there was one more element on the cache
than there actually was. This happened since element 0
exists but is not used. This code allocates the correct
number of useable elements and reports the number of
actually used elements. The previous code only allowed
MCacheMaxObjectCount-1 objects to be stored in the

[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

*) 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>]

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

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]

*) Change the verbage on the ScoreBoardFile in our default configs.
Also change the default to be commented out (unspecified) so we
get anonymous shared memory by default. [Aaron Bannert]
*) Implement new ScoreBoardFile directive logic. This affects how
we create the scoreboard's shared memory segment. If the directive
is present, a name-based segment is created. If the directive is
not present, first an anonymous segment is created, and if that
fails, a name-based segment is created from a file of the name
DEFAULT_SCOREBOARD. This gives third-party applications the
ability to access our scoreboard. [Aaron Bannert]

of the cgid process. [Aaron Bannert]
*) Add signal handling back in to the worker MPM for the one_process
(-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
*) Performance: Reuse per-connection transaction pools in the
worker MPM, rather than destroying and recreating them. [Brian Pane]
*) Remove all signals from the worker MPM's child process. Instead,
the parent uses the Pipe of Death for all communication with the
child processes. [Ryan Bloom]
Changes with Apache 2.0.32
*) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
default if the directive is not specified. This mirrors older
behavior without changes to the httpd.conf. [William Rowe]
*) 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
has been opened. [William Rowe]
*) Win32: substantial cleanup to the mpm_winnt code for legibility and
to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
*) Win32: apache -k shutdown now behaves like apache -k stop.
[Bill Stoddard]
*) Fix prefork to not kill the parent if a child hits a resource shortage
on accept(). [Greg Ames]
*) Fix seg faults that occur when what should be the httpd request line
starts with \r\n followed by garbage. [Greg Ames]
*) Allow statically linked support binaries with the new
--enable-static-support flag, and enable this behavior in
the binbuild script. Also add a new --enable-static-htdbm
flag. [Aaron Bannert]
*) Allow mod_autoindex to serve symlinks if permitted and attempt to
do only one stat() call when generating the directory listings.
[Justin Erenkrantz]
*) Fix resolve_symlink to save the original symlink name if known.
[Justin Erenkrantz]
*) Be a bit more sane with regard to CanonicalNames. If the user has
specified they want to use the CanonicalName, but they have not
configured a port with the ServerName, then use the same port that
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
data arrives. [Jeff Trawick]
*) 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.
[Ryan Bloom]
*) suexec: Allow HTTPS and SSL_* environment variables to be passed
through to CGI scripts. PR 9163
[Brian Reid <breid>,

*) Make sure that we use the expat from our source

[Jeff Trawick]
*) mod_cgid: Add retry logic for when the daemon can't fork fast
enough to keep up with new requests. Start using

*) apxs: LTFLAGS envvar can override default libtool options. Try
"LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
the covers. [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]
Changes with Apache 2.0.31
*) Create the scoreboard (in the parent) in a global pool context,
so it survives graceful restarts. This fixes a SEGV during
graceful restarts. [Aaron Bannert]
*) 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
worker MPM [Brian Pane]
*) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
the incoming host header through to the proxied server
[Geoff <g.russell>]
*) New Directive Option for ProxyPass. It now can block a location
from being proxied [Jukka Pihl <jukka.pihl>]
*) 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
allow modules to bypass the usual filter name lookup when
adding hard-coded filters to a request [Brian Pane]
*) caching should now work on subrequests (still very experimental)
[Ian Holsman]
*) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
*) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
[Justin Erenkrantz]
*) Refactor ap_rgetline so that it does not use an internal brigade.
Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
*) Remove mod_auth_db. [Justin Erenkrantz]
*) Do not install unnecessary pcre headers like config.h and internal.h.
[Joe Orton <joe>]
*) Change in quick_hanlder behavior for subrequests. it now passes DONE
(as it does for a normal request). quick_handled sub-requests now work
in mod-include [Ian Holsman]
*) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
'CONTENT' one, as it needs to run AFTER all content headers
*) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
[Lars Eilebrecht]
*) Split out blocking from the mode in the input filters.
[Justin Erenkrantz]
*) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
*) Cause Win32 to capture all child-worker process errors in
Apache to the main server error log, until the child can
open its own error logs. [William Rowe]
*) HPUX 11.*: Do not kill the child process when accept()
returns ENOBUFS on HPUX 11.*. (ported from th 1.3 patch)
[Madhusudan Mathihalli <madhusudan_mathihalli>, Bill Stoddard]
*) Fix a problem in the parsing of the <Proxy foo> directive.
[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
