(markt) 59904: Add a limit (default 200) for the number of cookies allowed per request. Based on a patch by gehui. (markt) Make timing attacks against the Realm implementations harder. (schultz) Refactor the code that implements the requirement that a call to complete() or dispatch() made from a non-container thread before the container initiated thread that called startAsync() completes must be delayed until the container initiated thread has completed. Rather than implementing this by blocking the non-container thread, extend the internal state machine to track this. This removes the possibility that blocking the non-container thread could trigger a deadlock. (markt)

(markt) 59449: In ContainerBase, ensure that the process to remove a child container is the reverse of the process to add one. Patch provided by Huxing Zhang. (markt) RMI Target related memory leaks are avoidable which makes them an application bug that needs to be fixed rather than a JRE bug to work around. Therefore, start logging RMI Target related memory leaks on web application stop. Add an option that controls if the check for these leaks is made. Log a warning if running on Java 9 with this check enabled but without the command line option it requires. (markt) Fix a potential concurrency issue with the web application class loader and concurrent reads and writes of the resource cache. (markt) 59619: Within the web application class loader, always use path as the key for the resource cache to improve the hit ratio.

(schultz) 58900: Correctly undeploy symlinked resources and prevent an infinite cycle of deploy / undeploy. (markt) Protect initialization of ResourceLinkFactory when running with a SecurityManager. (kkolinko) Extend the feature available in the cluster session manager implementations that enables session attribute replication to be filtered based 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) 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) 58905: Ensure that Tomcat.silence() silences the correct logger and respects the current setting. (markt) 58946: Ensure that the request parameter map remains immutable when processing via a RequestDispatcher. (markt)

56917: As per RFC7231 (HTTP/1.1), allow HTTP/1.1 and later redirects to use relative URIs. This is controlled by a new attribute useRelativeRedirects on the Context and defaults to true. (markt) 58660: Correct a regression in 7.0.66 caused by the change that moved the redirection for context roots from the Mapper to the Default Servlet. (markt) Fixed potential NPE in HostConfig while deploying an application. Issue reported by coverity scan. (violetagg) 58655: Fix an IllegalStateException when calling HttpServletResponse.sendRedirect() with the RemoteIpFilter. This was caused by trying to correctly generate the absolute URI for the redirect. With the fix for 56917, redirects may now be relative making the sendRedirect() implementation for the RemoteIpFilter much simpler. This also addresses issues where the redirect may not have behaved as expected when redirecting from http to https to from https to http. (markt)

(markt) Add support for DIGEST authentication to the JNDIRealm. Based on a patch by Alexis Hassler. (markt) 58603: Ensure that HttpServletRequest.getRequestURL() returns the correct value when using the RemoteIpFilter. (markt) Ensure that in an embedded Tomcat the logging configuration is not lost during garbage collection. (violetagg) 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) 58635: Enable break points to be set within agent code when running Tomcat with a Java agent. Based on a patch by Huxing Zhang.

57136#c25: Implement a setting that controls what quoting rule is used when parsing EL expressions in attributes on a JSP page (chapter JSP.1.6 of specification). The setting name is quoteAttributeEL and it is configured as initialisation parameter of JSP Servlet (per web application configuration is possible) and as a command line option for JspC. The default value was changed to true, which restores behaviour implemented in Tomcat 7.0.64. It means that attribute quoting is applied on top of EL quoting. This provides better compatibility with older versions of Tomcat and other implementations. (kkolinko)

Correct some edge cases in RequestUtil.normalize(). (markt) 58275: The IBM JREs accept cipher suite names starting with TLS_ or SSL_ but when listing the supported cipher suites only the SSL_ version is reported. This can break Tomcat's check that at least one requested cipher suite is supported. Tomcat now includes a work-around so either form of the cipher suite name can be used when running on an IBM JRE. (markt) 58357: For reasons not currently understood when the APR/native connector is used with OpenSSL reads can return an error code when there is no apparent error. This was work-around for HTTP upgrade connections by treating this as EAGAIN. The same fix has now been applied to the standard HTTP connector.

(markt) Add text/javascript,application/javascript to the default list of compressable MIME types. (violetagg) 58103: When pipelining requests, and the previous request was an async request, ensure that the socket is removed from the waiting requests so that the async timeout thread doesn't process it during the next request. (markt) Fix a concurrency issue that meant that a change in socket timeout (e.g. when switching to asynchronous I/O) did not always take effect immediately. (markt) In the AJP and HTTP NIO connectors, ensure that the socket timeout is correctly set before adding the socket back to the poller for read. (markt) 58157: Ensure that the handling of async timeouts does not result in an unnecessary dispatch to a container thread that could result in the current socket being added to the Poller multiple times with multiple attempts to process the same event for the same socket. (markt) Correct a couple of edge cases in RequestUtil.normalize(). (markt)

Fix potential NPE in QueryTimeoutInterceptor. (kfujino) Add support for stopping the pool cleaner via JMX. (kfujino) The fairness attribute and ignoreExceptionOnPreLoad attribute do not allow a change via JMX. (kfujino) If the timeBetweenEvictionRunsMillis attribute is changed via jmx, it should restart the pool cleaner because this attribute affects the execution interval of the pool cleaner. (kfujino) Eliminate the dependence on maxActive of busy queues and idle queue in order to enable the expansion of the pool size via JMX. (kfujino)

The meaning of the value zero for the maxPostSize has also been changed to mean a limit of zero rather than no limit to align it with maxSavePostSize and to be more intuitive. (markt) 54618: Add a new HttpHeaderSecurityFilter that adds the Strict-Transport-Security, X-Frame-Options and X-Content-Type-Options HTTP headers to the response. (markt) Add a workaround for issues with SPNEGO authentication when running on Java 8 update 40 and later. The workaround should be safe for earlier Java versions but it can be disabled with the applyJava8u40Fix attribute of the SPNEGO authenticator if necessary.

Allow logging of the remote port in the access log using the format pattern %{remote}p. (rjung) 57765: When checking last modified times as part of the automatic deployment process, account for the fact that File.lastModified() has a resolution of one second to ensure that if a file has been modified within the last second, the latest version of the file is always used. Note that a side-effect of this change is that files with modification times in the future are treated as if they are unmodified. (markt) Align redeploy resource modification checking with reload modification checking so that now, in both cases, a change in modification time rather than an increase in modification time is used to determine if the resource has changed. (markt) Cleanup o.a.tomcat.util.digester.Digester from debug messages that do not give any valuable information. Patch provided by Polina Genova. (violetagg) 57772: When reloading a web application and a directory representing an expanded WAR needs to be deleted, delete the directory after the web application has been stopped rather than before to avoid potential ClassNotFoundExceptions.

(markt) 57776: Revert the 8.0.21 fix for the permessage-deflate implementation and incorrect op-codes since the fix was unnecessary (the bug only affected trunk) and the fix broke rather than fixed permessage-deflate if an uncompressed message was converted into more than one compressed message. (markt) Fix log name typo in WsRemoteEndpointImplServer class, caused by a copy-paste. (markt/kkolinko) 57788: Avoid NPE when looking up a class hierarchy without finding anything. (remm) Make WebSocket client more robust when handling errors during the close of a WebSocket session. (markt)

Fix a concurrency issue when a backup message that has all session data and a backup message that has diff data are processing at the same time. This fix ensures that MapOwner is set to ReplicatedMapEntry. (kfujino) Clarify the handling of Copy message and Copy nodes. (kfujino) Copy node does not need to send the entry data. It is enough to send only the node information of the entry. (kfujino) ReplicatedMap should send the Copy message when replicating. (kfujino) Fix behavior of ReplicatedMap when member has disappeared. If map entry is primary, rebuild the backup members. If primary node of map entry has disappeared, backup node is promoted to primary. (kfujino) When a map member has been added to ReplicatedMap, make sure to add it to backup nodes list of all other members. (kfujino)

(jboynes/markt) 57602: Ensure that HEAD requests return the correct content length (i.e. the same as for a GET) when the requested resource includes a resource served by a servlet that extends HttpServlet. (markt) 57621: When an async request completes, ensure that any remaining request body data is swallowed. (markt) 57637: Do not create unnecessary sessions when using PersistentValve. (jboynes/fschumacher) 57645: Correct a regression in the fix for 57190 that incorrectly required the path passed to ServletContext.getContext(String) to be an exact match to a path to an existing context.

(markt) 57638: Avoid an IllegalArgumentException when an AJP request body chunk larger than the socket read buffer is being read. This typically requires a larger than default AJP packetSize. (markt) 57674: Avoid a BufferOverflowException when an AJP response body chunk larger than the socket write buffer is being written. This typically requires a larger than default AJP packetSize. (markt) Refactor Connector authentication (only used by AJP) into a separate method. (markt) 57708: Implement a new feature for AJP connectors - Tomcat Authorization. If the new tomcatAuthorization attribute is set to true (it is disabled by default) Tomcat will take an authenticated user name from the AJP protocol and use the appropriate Realm for the request to authorize (i.e. add roles) to that user. (markt) Fix an issue that meant that any pipe-lined data read by Tomcat before an asynchronous request completed was lost during the completion of the asynchronous request. This mean that the pipe-lined request(s) would be lost and/or corrupted. (markt) Update the minimum recommended version of the Tomcat Native library (if used) to 1.1.33. (markt)

Coyote

56518: When using NIO, do not attempt to write to the socket if the thread is marked interrupted as this will lead to a connection limit leak. This fix was based on analysis of the issue by hanyong. (markt) 56521: Re-use the asynchronous write buffer between writes to reduce allocation and GC overhead. Based on a patch by leonzhx. Also make the buffer size configurable and remove copying of data within buffer when the buffer is only partially written on a subsequent write. (markt) Correct a copy/paste error and return a 500 response rather than a 400 response when an internal server error occurs on early stages of request processing. (markt) 56582: Use switch(actionCode) in processors instead of a chain of "elseif"s. (kkolinko) Fix CVE-2014-0227: Various improvements to ChunkedInputFilter including clean-up, i18n for error messages and adding an error flag to allow subsequent attempts at reading after an error to fail fast. (markt) If request contains an unrecognized Expect header, respond with error 417 (Expectation Failed), according to RFC2616 chapter 14.20. (markt) When an error occurs after the response has been committed close the connection immediately rather than attempting to finish the response to make it easier for the client to differentiate between a complete response and one that failed part way though. (markt) 56620: Avoid bogus access log entries when pausing the NIO HTTP connector and ensure that access log entries generated by error conditions use the correct request start time. (markt) Fix CVE-2014-0230: Add a new limit, defaulting to 2MB, for the amount of data Tomcat will swallow for an aborted upload. The limit is configurable by maxSwallowSize attribute of an HTTP connector. (markt) Allow to configure maxSwallowSize attribute of an HTTP connector via JMX. (kkolinko) 56661: Fix getLocalAddr() for AJP connectors. The complete fix is only available with a recent AJP forwarder like the forthcoming mod_jk 1.2.41.

(violetagg) 56561: Avoid NoSuchElementException while handling attributes with empty string value. (violetagg) 56581: If an error on a JSP page occurs when response has already been committed, do not clear the buffer of JspWriter, but flush it. It will make more clear where the error occurred. (kkolinko) 56612: Correctly parse two consecutive escaped single quotes when used in UEL expression in a JSP. (markt) Move code that parses EL expressions within JSP template text from Parser to JspReader class for better performance. (kkolinko)

WebSocket

56577: Improve the executor configuration used for the callbacks associated with asynchronous writes. (markt)

Web applications

Set the path for cookies created by the examples web application so they only returned to the examples application. This reduces the opportunity for using such cookies for malicious purposes should the advice to remove the examples web application from security sensitive systems be ignored. (markt/kkolinko) Attempt to obfuscate session cookie values associated with other web applications when viewing HTTP request headers with the Request Header example from the examples web application. This reduces the opportunity to use this example for malicious purposes should the advice to remove the examples web application from security sensitive systems be ignored. (markt)

Update optional Checkstyle library to 5.7. (kkolinko) 56685: Add quotes necessary for daemon.sh to work correctly on Solaris. Based on a suggestion by lfuka. (markt) 56596: Update to Tomcat Native Library version 1.1.31 to pick up the Windows binaries that are based on OpenSSL 1.0.1h. (markt)

Catalina

Fix custom UTF-8 decoder so that a byte of value 0xC1 is always rejected immediately as it is never valid in a UTF-8 byte sequence. Update UTF-8 decoder tests to account for UTF-8 decoding improvements in Java 8. The custom UTF-8 decoder is still required due to bugs in the UTF-8 decoder provided by Java. Java 8's decoder is better than Java 7's but it is still buggy. (markt) 56027: Add more options for managing FIPS mode in the AprLifecycleListener. (schultz/kkolinko) 56321: When a WAR is modified, undeploy the web application before deleting any expanded directory as the undeploy process may refer to classes that need to be loaded from the expanded directory.

(kkolinko) Correct regression introduced in r797162 that broke authentication of users when using the JAASMemoryLoginModule. (markt) 56501: HttpServletRequest.getContextPath() should return the undecoded context path used by the user agent. (markt) 56523: When using SPNEGO authentication, log the exceptions associated with failed user logins at debug level rather than error level. (markt) 56536: Ensure that HttpSessionBindingListener.valueUnbound() uses the correct class loader when the SingleSignOn valve is used. (markt)

(markt) 56529: Avoid NoSuchElementException while handling attributes with empty string value in custom tags. Patch provided by Hariprasad Manchi. (violetagg)

Cluster

Remove cluster and replicationValve from cluster manager template. These instance are not necessary to template. (kfujino) Add support for cross context session replication to org.apache.catalina.ha.session.BackupManager. (kfujino) Remove the unnecessary cross context check. It does not matter whether the context that is referenced by other context is set to crossContext=true. The context that refers to the different context must be set to crossContext=true. (kfujino) Move to org.apache.catalina.ha.session.ClusterManagerBase common logics of org.apache.catalina.ha.session.BackupManager and org.apache.catalina.ha.session.DeltaManager. (kfujino) Simplify the code of o.a.c.ha.tcp.SimpleTcpCluster. In order to add or remove cluster valve to Container, use pipeline instead of IntrospectionUtils. (kfujino) There is no need to set cluster instance when SimpleTcpCluster.unregisterClusterValve is called. Set null than cluster instance for cleanup. (kfujino) Backport refactoring of AbstractReplicatedMap to implement Map rather than extend ConcurrentHashMap to enable Tomcat 7 to be built with Java 8. (markt)

WebSocket

56343: Avoid a NPE if Tomcat's Java WebSocket 1.0 implementation is used with the Java WebSocket 1.0 API JAR from the reference implementation. (markt) Increase the default maximum size of the executor used by the WebSocket implementation for call backs associated with asynchronous writes from 10 to 200. (markt) Add a warning if the thread group created for WebSocket asynchronous write call backs can not be destroyed when the web application is stopped.

(markt) 56236: Enable Tomcat to work with alternative Servlet and JSP API JARs that package the XML schemas in such as way as to require a dependency on the JSP API before enabling validation for web.xml. Tomcat has no such dependency. (markt) 56246: Fix NullPointerException in MemoryRealm when authenticating an unknown user. (markt) 56248: Allow the deployer to update an existing WAR file without undeploying the existing application if the update flag is set. This allows any existing custom context.xml for the application to be retained. To update an application and remove any existing context.xml simply undeploy the old version of the application before deploying the new version. (markt) Fix CVE-2014-0096: Redefine the globalXsltFile initialisation parameter of the DefaultServlet as relative to CATALINA_BASE/conf or CATALINA_HOME/conf. Prevent user supplied XSLTs used by the DefaultServlet from defining external entities.

(markt) 56293: Cache resources loaded by the class loader from /META-INF/services/ for better performance for repeated look ups. (markt)

Coyote

53119: Make sure the NIO AJP output buffer is cleared on any error to prevent any possible overflow if it is written to again before the connection is closed. This extends the original fix for the APR/native output buffer to the NIO connector. (kkolinko) 56172: Avoid possible request corruption when using the AJP NIO connector and a request is sent using more than one AJP message. Patch provided by Amund Elstad.

(markt) 56208: Restore the validateXml option to Jasper that was previously renamed validateTld. Both options are now supported. validateXml controls the validation of web.xml files when Jasper parses them and validateTld controls the validation of *.tld files when Jasper parses them. (markt) 56223: Throw an IllegalStateException if a call is made to ServletContext.setInitParameter() after the ServletContext has been initialized. (markt) 56265: Do not escape values of dynamic tag attributes containing EL expressions. (kkolinko) Make the default compiler source and target versions for JSPs Java 6 since Tomcat 7 requires Java 6 as a minimum. (markt) 56283: Update to the Eclipse JDT Compiler P20140317-1600 which adds support for Java 8 syntax to JSPs. Add support for value "1.8" for the compilerSourceVM and compilerTargetVM options.

(markt) 56304: Add a note to the documentation about not using WebSocket with BIO HTTP in production. (markt)

Other

56143: Improve service.bat so that it can be launched from a non-UAC console. This includes using a single call to tomcat7.exe to install the Windows service rather than three calls, and using command line arguments instead of environment variables to pass the settings. (markt/kkolinko) Fix regression in 7.0.52: when using service.bat install to install the service the values for --StdOutput, --StdError options were passed as blank instead of "auto". (kkolinko) Align options between service.bat and exe Windows installer. For service.bat the changes are in --Classpath, --DisplayName, --StartPath, --StopPath. For exe installer the changes are in --JvmMs, --JvmMx options, which are now 128 Mb and 256 Mb respectively instead of being empty. Explicitly specify --LogPath path when uninstalling Windows service, avoiding default value for that option. (kkolinko) Simplify Windows *.bat files: remove %OS% checks, as java 6 does not run on ancient non-NT operating systems. (kkolinko) 56137: Explicitly use the BIO connector in the SSL example in server.xml so it doesn't break if APR is enabled. (markt) 56139: Avoid a web application class loader leak in some unit tests when running on Windows. (markt) Correct build script to avoid building JARs with empty packages.

(markt) 55937: When deploying applications, treat a context path of /ROOT as equivalent to /. (markt) 55943: Improve the implementation of the class loader check that prevents web applications from trying to override J2SE implementation classes. As part of this fix, refactor the way a null parent class loader is handled which enables a number of null checks and object creation calls to be removed. Note that this change means that, by default, the web application class loader is now a higher priority for loading classes than the system class loader. (markt) 55958: Differentiate between foo.war the WAR file and foo.war the directory. (markt) 55960: Improve the single sign on (SSO) unit tests. Patch provided by Brian Burch. (markt) 55974: Retain order when reporting errors and warnings while parsing XML configuration files. (markt) 56013: Fix issue with SPNEGO authentication when using IBM JREs.

Patch by Juan Carlos Estibariz. (markt) 56025: When creating a WebSocket connection, always call ServerEndpointConfig.Configurator.getNegotiatedSubprotocol() and always create the EndPoint instance after calling ServerEndpointConfig.Configurator.modifyHandshake(). (markt) 56032: Ensure that the WebSocket connection is closed after an IO error or an interrupt while sending a WebSocket message. (markt) 56042: If a request in async mode has an error but has already been dispatched don't generate an error page in the ErrorReportValve so the dispatch target can handle it. (markt) Add missing javax.annotation.sql.* classes to annotations-api.jar. (markt) The type of logger attribute of Context MBean should be not org.apache.commons.logging.Log but org.apache.juli.logging.Log. (kfujino) 56082: Fix a concurrency bug in JULI's LogManager implementation. (markt) 56096: When the attribute rmiBindAddress of the JMX Remote Lifecycle Listener is specified it's value will be used when constructing the address of a JMX API connector server. Patch is provided by Jim Talbut. (violetagg) When environment entry with one and the same name is defined in the web deployment descriptor and with annotation then the one specified in the web deployment descriptor is with priority.

(kkolinko) 55973: Fix processing of XML schemas when validation is enabled in Jasper. (kkolinko) 56010: Don't throw an IllegalArgumentException when JspFactory.getPageContext is used with JspWriter.DEFAULT_BUFFER. Based on a patch by Eugene Chung. (markt) 56012: When using the extends attribute of the page directive do not import the super class if it is in an unnamed package as imports from unnamed packages are now explicitly illegal. (markt) 56029: A regression in the fix for 55198 meant that when EL containing a ternary expression was used in an attribute a compilation error would occur for some expressions. (markt) Correct several errors in jspxml Schema and DTD. (kkolinko) Change default value of the blockExternal attribute of JspC task. The default value is true. Add support for -no-blockExternal switch when JspC is run as a standalone application. (kkolinko)

Extras

55166, 56045: Copy the XML schemas used for validation that are packaged in jsp-api.jar to servlet-api.jar so that an embedded Tomcat instance can start without Jasper being available. This also enables validation to work without Jasper being available. (markt/kkolinko) 56039: Enable the JmxRemoteLifecycleListener to work over SSL. Patch by esengstrom. (markt)

Other

55743: Enable the stop script to work when the shutdown port is disabled and a PID file is defined. This is only available on platforms that use catalina.sh. (markt) 55986: When forcing Tomcat to stop via kill -9 $CATALINA_PID, the catalina.sh script could incorrectly report that Tomcat had not yet completely stopped when it had. Based on a patch by jess. (markt) Package correct license and notice files with embedded JARs. (markt) Remove svn keywords (such as $Id) from source files and documentation. (kkolinko) Fix CVE-2014-0050, a denial of service with a malicious, malformed Content-Type header and multipart request processing. Fixed by merging latest code (r1565163) from Commons FileUpload.

Now (assuming automatic deployment is enabled) it will trigger a redeploy of the web application. (markt) Fix string comparison in HostConfig.setContextClass(). (kkolinko) Streamline handling of WebSocket messages when no handler is configured for the message currently being received. (markt) Handle the case where a WebSocket annotation configures a message size limit larger than the default permitted by Tomcat.

(markt) 55905: Prevent a NPE when web.xml references a taglib file that does not exist. Provide better error message. (violetagg)

Coyote

When using the BIO connector with an internal executor, do not display a warning that the executor has not shutdown as the default configuration for BIO connectors is not to wait. This is because threads in keep-alive connections cannot be interrupted and therefore the warning was nearly always displayed. (markt)

Jasper

JspC uses servlet context initialization parameters to pass configuration so ensure that the servlet context used supports initialization parameters. (markt)

Cluster

In AbstractReplicatedMap#finalize, remove rpcChannel from channel Listener of group channel before sending MapMessage.MSG_STOP message. This prevents that the node that sent the MapMessage.MSG_STOP by normal shutdown is added to member map again by ping at heartbeat thread in the node that received the MapMessage.MSG_STOP. (kfujino) Add time stamp to GET_ALL_SESSIONS message. (kfujino)

Web applications

Fix the sample configuration of StaticMembershipInterceptor in order to prevent warning log. uniqueId must be 16 bytes. (kfujino)

(markt) 55664: Correctly handle JSR 356 WebSocket Encoder, Decoder and MessageHandler implementations that use a generic type such as Encoder.Text<List<String>>. Includes a test case by Niki Dokovski. (markt) Correctly handle WebSocket Encoders, Decoders and MessageHandlers that use arrays of generic types. (markt) 55681: Ensure that the WebSocket session is made available to MessageHandler method calls. (markt) Updated servlet spec version and documentation section-number reported when JAR files are rejected for containing a trigger class (e.g. javax.servlet.Servlet). (schultz) Modify the WebSocket handshake process so that the user properties Map exposed by the ServerEndpointConfig during the call to Configurator.modifyHandshake() is unique to the connection rather than shared by all connections associated with the Endpoint. This allows for easier configuration of per connection properties from within modifyHandshake(). (markt) 55684: Log a warning but continue if the memory leak detection code is unable to access all threads to check for possible memory leaks when a web application is stopped. (markt) Define the web-fragment.xml in tomcat7-websocket.jar as a Servlet 3.0 web fragment rather than as a Servlet 3.1 web fragment. (markt) 55715: Add a per web application executor to the WebSocket implementation and use it for calling SendHandler.onResult() when there is a chance that the current thread also initiated the write. (markt) Prevent file descriptors leak and ensure that files are closed when configuring the web application. (violetagg) Fixed the name of the provider-configuration file located in tomcat7-websocket.jar!/META-INF/services that exposes information for javax.websocket.server.ServerEndpointConfig$Configurator implementation.

Includes a test case based on code contributed by Todd West. (markt) 55778: Add an option to the JNDI Realm to control the QOP used for the connection to the LDAP server after authentication when using SPNEGO with delegated credentials. This value is used to set the javax.security.sasl.qop environment property for the LDAP connection. (markt) 55798: Log an error if the MemoryUserDatabase is unable to find the specified user database file. (markt) 55799: Correctly enforce the restriction in JSR356 that no more than one data message may be sent to a remote WebSocket endpoint at a time. (markt) When Catalina parses TLD files, always use a namespace aware parser to be consistent with how Jasper parses TLD files. The tldNamespaceAware attribute of the Context is now ignored. (markt) Deprecate the tldNamespaceAware Context attribute as TLDs are always parsed with a namespace aware parser. (markt) Correct a logic error that meant that unpackWARs was ignored and the WAR was always expanded if a WAR failed to deploy. (markt) Add support for defining copyXML on a per Context basis. (markt) Define the expected behaviour of the automatic deployment and align the implementation to that definition. (markt) When running under a security manager, change the default value of the Host's deployXML attribute to false. (markt) If a Host is configured with a value of false for deployXML, a web application has an embedded descriptor at META-INF/context.xml and no explicit descriptor has been defined for this application, do not allow the application to start. The reason for this is that the embedded descriptor may contain configuration necessary for secure operation such as a RemoteAddrValve. (markt) Prevent an NPE in the WebSocket ServerContainer when processing an HTTP session end event. (markt) 55801: Add the ability to set a custom SSLContext to use for client wss connections. Patch provided by Maciej Lypik. (markt) 55804: If the GSSCredential for the cached Principal expires when using SPNEGO authentication, force a re-authentication. (markt) 55811: If the main web.xml contains an empty absolute-ordering element and validation of web.xml is not enabled, skip parsing any web-fragment.xml files as the result is never used. (markt) 55839: Extend support for digest prefixes {MD5}, {SHA} and {SSHA} to all Realms rather than just the JNDIRealm. (markt) 55842: Ensure that if a larger than default response buffer is configured that the full buffer is used when a Servlet outputs via a Writer. (markt) 55851: Further fixes to enable SPNEGO authentication to work with IBM JDKs. Based on a patch by Arunav Sanyal. (markt) Fix CVE-2013-4590: Add an option to the Context to control the blocking of XML external entities when parsing XML configuration files and enable this blocking by default when a security manager is used. The block is implemented via a custom resolver to enable the logging of any blocked entities. (markt)

Coyote

Implement a number of small refactorings to the APR/native handler for upgraded HTTP connections. (markt) Fix an issue with upgraded HTTP connections over HTTPS (e.g. secure WebSocket) when using the APR/native connector that resulted in the unexpected closure of the connection. (markt) Ensure that the application class loader is used when calling the ReadListener and WriteListener methods when using non-blocking IO. A side effect of not doing this was that JNDI was not available when processing WebSocket events. (markt) Make the time that the internal executor (if used) waits for request processing threads to terminate before continuing with the connector stop process configurable. (markt) 55749: Improve the error message when SSLEngine is disabled in the AprLifecycleListener and SSL is configured for an APR/native connector. (markt) If a request that includes an Expect: 100-continue header receives anything other than a 2xx response, close the connection This protects against misbehaving clients that may not sent the request body in that case and send the next request instead. (markt) Improve the parsing of trailing headers in HTTP requests. (markt)

Jasper

55735: Fix a regression caused by the fix to 55198. When processing JSP documents, attributes in XML elements that are template content should have their text xml-escaped, but output of EL expressions in them should not be escaped. (markt) 55807: The JSP compiler used a last modified time of -1 for TLDs in JARs expanded in to WEB-INF/classes (IDEs often do this expansion) when creating the dependency list for JSPs that used that TLD. This meant JSPs using that TLD were recompiled on every access. (markt)

Cluster

Add log message that initialization of AbstractReplicatedMap has been completed. (kfujino) The logger of AbstractReplicatedMap should be non-static in order to enable logging of each application. Side-effects of this change is to throw RuntimeException in MapMessage#getKey() and getValue() instead of Null return and error log. (kfujino) Simplify the code of DeltaManager#startInternal(). Reduce unnecessary nesting for acquisition of cluster instance. (kfujino) Remove unnecessary attributes of stateTransferCreateSendTime and receiverQueue from cluster manager template. These attributes should not be defined as a template. (kfujino) Fix MBean attribute definition of stateTransfered. The method name is not isStateTransfered() but getStateTransfered(). (kfujino) Correct stop failure log of cluster. Failure cause is not only Valve. (kfujino) Remove unnecessary sleep when sending session blocks on session sync phase. (kfujino) Expose stateTimestampDrop of org.apache.catalina.ha.session.DeltaManager via JMX. (kfujino) When the ping timeouted, make sure that memberDisappeared method is not called by specifying the members that has already been removed. (kfujino) Add log message of session relocation when member disappeared. (kfujino) If ping message fails, prevent wrong timeout detection of normal member that is no failure members. (kfujino)

Web applications

Add some documentation on the SSL configuration options for WebSocket clients. (markt) Add to cluster document a description of notifyLifecycleListenerOnFailure and heartbeatBackgroundEnabled. (kfujino) Update the documentation with information for WebSocket 1.0 specification and javadoc. (violetagg) 55703: Clarify the role of the singleton attribute for JNDI resource factories. (markt) 55746: Add documentation on the allRolesMode to the CombinedRealm and LockOutRealm. Patch by Cédric Couralet. (markt) Expand the information on web applications that ship as part of Tomcat in the security how-to section of the documentation web application. (markt) Expand the description of the WebSocket buffers in the documentation web application to clarify their purpose. (markt) Correct the documentation for Cluster manager. (kfujino) Add information on how to configure integrated Windows authentication when Tomcat is running on a non-Windows host. (markt)

Catalina

Only send a WebSocket close message on an IOException if the client has not yet received a close control message from the server as the IOException may be in response to the client continuing to send a message after the server sent a close control message. (markt) 49134: Ensure nested realms are correctly destroyed, when a CombinedRealm is destroyed. This ensures that the associated MBeans are deregistered. (markt)

Coyote

Refactor APR/native connector to reduce the scope of localAddList. (markt) 55602: Ensure that sockets removed from the Poller and then closed in the APR/native connector are removed and then closed in a thread-safe manner. (markt) Update the APR/native connector to version 1.1.29. (violetagg)

(kfujino) Handle the case when a user closes the browser whilst playing the snake game in the JSR356 WebSocket examples. (markt) Ensure Javadoc comments are associated with the correct elements in org.apache.tomcat.jni.Poll. (markt) Expand Context documentation for the use of sessionCookiePath="/" to make the implications for session fixation protection clearer. (markt) 55629: Ensure that the JMX notification listener added during initialization of the servlet org.apache.catalina.manager.StatusManagerServlet is removed in the destroy phase.
