Changelog

Tomcat 6.0.45 (jfclere)
Catalina
fix Back-port various improvements to the AprLifecycleListener including the fix for 57021 that improves logging when the Tomcat-Native DLL fails to load. (markt)
add 57154: Add support for web applications (Context elements) that do not have a docBase. This is intended for use when embedding, such as Tomcat unit tests, when a web application is configured programmatically and does not serve any files. Based on a patch provided by Huxing Zhang. (kkolinko)
add 57741: Enable the CGI servlet to use the standard error page mechanism. Note that if the CGI servlet's debug init parameter is set to 10 or higher then the standard error page mechanism will be bypassed and a debug response generated by the CGI servlet will be returned instead. (markt)
fix 57896: Support defensive copying of "cookie" header so that unescaping double quotes in a cookie value does not corrupt original value of "cookie" header. This is an opt-in feature, enabled by org.apache.tomcat.util.http.ServerCookie.PRESERVE_COOKIE_HEADER or org.apache.catalina.STRICT_SERVLET_COMPLIANCE system property. (kkolinko)
fix 58031: Make the (first) reason parameter parsing failed available as a request attribute and then use it to provide a better status code via the FailedRequstFilter (if configured). (markt)
fix 58313: Fix concurrent access of encoders map when clearing encoders during Comet processing. (markt)
fix 58508: Escape role names when generating associated MBeans in case the role name contains characters not permitted in an MBean name. (markt)
fix 58582: Combined realm should perform background processing on its sub-realms. Based upon a patch provided by Aidan. (kkolinko)
add Move the functionality that provides redirects for context roots and directories where a trailing / is added from the Mapper to the DefaultServlet. This enables such requests to be processed by any configured Valves and Filters before the redirect is made. This behaviour is configurable via the mapperContextRootRedirectEnabled and mapperDirectoryRedirectEnabled attributes of the Context which may be used to restore the previous behaviour. (markt)
fix 58635: Enable break points to be set within agent code when running Tomcat with a Java agent. Based on a patch by Huxing Zhang. (markt)
fix Add the StatusManagerServlet to the list of Servlets that can only be loaded by privileged applications. (markt)
fix Remove redundant copy of catalina.properties from o.a.c.startup. Generate this copy during the ant "compile" task. (kkolinko)
fix 58817: Fix ArrayIndexOutOfBoundsException caused by MapperListener when ROOT context is being undeployed and mapperContextRootRedirectEnabled="false". (kkolinko)
fix 58836: Correctly merge query string parameters when processing a forwarded request where the target includes a query string that contains a parameter with no value. (markt/kkolinko)
add Allow singleton server instance stored by ServerFactory to be cleared. Allow ResourceLinkFactory to be initialized more than once. This is used by unit tests when running several copies of Tomcat sequentially in the same JVM. When running with a SecurityManager the initialization method of ResourceLinkFactory is protected by requiring a RuntimePermission. (kkolinko)
add Extend the feature available in the cluster session manager implementations that enables session attribute replication to be filtered bases on attribute name to all session manager implementations. Note that configuration attribute name has changed from sessionAttributeFilter to sessionAttributeNameFilter. Apply the filter on load as well as unload to ensure that configuration changes made while the web application is stopped are applied to any persisted data. (markt)
add Extend the session attribute filtering options to include filtering based on the implementation class of the value and optional WARN level logging if an attribute is filtered. These options are available for all of the Manager implementations that ship with Tomcat. When a SecurityManager is used filtering will be enabled by default. (markt)
fix 58946: Ensure that the request parameter map remains immutable when processing via a RequestDispatcher. (markt)
Coyote
add Align the Java side of the tc-native connector with the Tomcat 7 implementation to ease future maintenance. (markt)
fix 51503: Add additional validation that prevents a connector from starting if it does not have a valid port number. (kkolinko)
add 52028: Add support for automatic binding to a free port by a connector if the special value of zero is used for the port. This is mainly useful in embedded and testing scenarios. (kkolinko)
fix 52926: Avoid NPE when an NIO Comet connection times out on one thread at the same time as it is closed on another thread. (markt/kkolinko)
fix 57943: Prevent the same socket being added to the cache twice. Patch based on analysis by Ian Luo / Sun Qi. (markt/kkolinko)
fix Improve HTTP header validation. (markt)

update Remove support for Intel Itanium CPU (i64, IA-64) in the Windows installer, as the current release of Tomcat Native does not have binaries for that processor architecture. (jfclere)
Tomcat 6.0.44 (jfclere)released 2015-05-12
Catalina
fix Correct typo in the message shown by HttpServlet for unexpected HTTP method. (kkolinko)

Coyote
fix 57234: Make SSL protocol filtering to remove insecure protocols case insensitive. Correct spelling of filterInsecureProtocols method. (kkolinko/schultz)
fix CVE-2014-0230: Add a new system property org.apache.coyote.MAX_SWALLOW_SIZE (defaults to 2MB) that limits amount of data Tomcat will swallow if request body has not been fully read during normal request processing, e.g. for an aborted upload. (Note: in Tomcat 7 and later this feature is configured by maxSwallowSize attribute on a connector). When applying the limit to a connection try to read that many bytes first before closing the connection to give the client a chance to read the response. (markt)
fix 57544: Fix a potential infinite loop when preparing a kept alive HTTP connection for the next request. (markt)
