not released Tomcat 9.0.0.M2

Catalina

  • Code: Refactor creation of MapperListener to ensure that the Mapper used is the Mapper associated with the Service for which the listener was created. (markt)
  • 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)
  • Code: Refactor Service.getContainer() to return an Engine rather than a Container. (markt)
  • Fix: 34319: Only load those keys in StoreBase.processExpire from JDBCStore, that are old enough, to be expired. Based on a patch by Tom Anderson. (fschumacher)
  • Add: 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)
  • Fix: 58629: Allow an embedded Tomcat instance to start when the Service has no Engine configured. (markt)
  • Fix: Correctly notify the MapperListener associated with a Service if the Engine for that Service is changed. (markt)
  • Add: Make a web application's CredentialHandler available through a context attribute. This allows a web application to use the same algorithm for validating or generating new stored credentials from cleartext ones. (schultz)
  • 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: Fixed potential NPE in HostConfig while deploying an application. Issue reported by coverity scan. (violetagg)
  • Fix: 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)
  • Fix: 58657: Exceptions in a Servlet 3.1 ReadListener or WriteListener do not need to be immediately fatal to the connection. Allow an error response to be written. (markt)
  • Fix: Correct implementation of validateClientProvidedNewSessionId so client provided session IDs may be rejected if validation is enabled. (markt)
  • Fix: 58701: Reset the instanceInitialized field in StandardWrapper when unloading a Servlet so that a new instance may be correctly initialized. (markt)
  • Update: Add a new flag aprPreferred to the Apr listener. if set to false, when using the connector defaults, it will use NIO + OpenSSL if tomcat-native is available, rather than the APR connector. (remm)
  • Fix: Add path parameter handling to HttpServletRequest.getContextPath(). This is a follow-up to the fix for 57215. (markt)
  • Fix: 58692: Make StandardJarScanner more robust. Log a warning if a class path entry cannot be scanned rather than triggering the failure of the web application. Includes a test case written by Derek Abdine. (markt)
  • Fix: 58702: Ensure an access log entry is generated if the client aborts the connection. (markt)
  • Fix: Fixed various issues reported by Findbugs. (violetagg)
  • Fix: 58735: Add support for the X-XSS-Protection header to the HttpHeaderSecurityFilter. Patch provided by Jacopo Cappellato. (markt)
  • Fix: Add the StatusManagerServlet to the list of Servlets that can only be loaded by privileged applications. (markt)
  • Fix: Simplify code and fix messages in org.apache.catalina.core.DefaultInstanceManager class. (kkolinko)
  • Fix: 58751: Correctly handle the case where an AsyncListener dispatches to a Servlet on an asynchronous timeout and the Servlet uses sendError() to trigger an error page. Includes a test case based on code provided by Andy Wilkinson.(markt)
  • Fix: Ensure that the proper file encoding if specified will be used when a readme file is served by DefaultServlet. (violetagg)
  • Fix: Fix declaration of localPort attribute of Connector MBean: it is read-only. (kkolinko)
  • Fix: 58766: Make skipping non-class files during annotation scanning faster by checking the file name first. Improve debug logging. (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)
  • Fix: Make sure that shared Digester is reset in an unlikely error case in HostConfig.deployWAR(). (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)
  • Code: Remove distributable and maxInactiveInterval from the Manager interface because the attributes are never used. The equivalent attributes from the Context always take precedence. (markt)
  • Fix: 58867: Improve checking on Host start for WAR files that have been modified while Tomcat has stopped and re-expand them if unpackWARs is true. (markt)
  • Fix: 58900: Correctly undeploy symlinked resources and prevent an infinite cycle of deploy / undeploy. (markt)

Coyote

  • Fix: 58621: The certificate chain cannot be set using the main certificate attribute, so restore the certificate chain property. (remm)
  • Fix: Allow a new SSL config type where a connector can use either JSSE or OpenSSL. Both could be allowed, but it would likely create support issues. This type is used by the OpenSSL implementation for NIOx. (remm)
  • Fix: Improve upgrade context classloader handling by using Context.bind and unbind. (remm)
  • Add: Improve OpenSSL keystore/truststore configuration by using the code from the JSSE implementation. (remm, jfclere)
  • Fix: Fix a potential loop when a client drops the connection unexpectedly. (markt)
  • Add: OpenSSL renegotiation support for client certificate authentication. (remm)
  • Fix: Fix NIO connector renegotiation. (remm)
  • Fix: 58659: Fix a potential deadlock during HTTP/2 processing when the connection window size is limited. (markt)

Jasper

  • Fix: 57136#c25: Change default value of quoteAttributeEL setting in Jasper to be true for better compatibility with other implementations and older versions of Tomcat. Add command line option -no-quoteAttributeEL in JspC. (kkolinko)
  • Fix: Fix handling of missing messages in org.apache.el.util.MessageFactory. (violetagg)

Cluster

  • Fix: Enable an explicit configuration of local member in the static cluster membership. (kfujino)
  • Fix: Fix potential integer overflow in DeltaSession. Reported by coverity scan. (fschumacher)
  • Fix: In order to avoid that the heartbeat thread and the background thread to run Channel.heartbeat simultaneously, if heartbeatBackgroundEnabled of SimpleTcpCluster set to true, ensure that the heartbeat thread does not start. (kfujino)

WebSocket

  • Add: 55006: The WebSocket client now honors the java.net.java.net.ProxySelector configuration (using the HTTP type) when establishing WebSocket connections to servers. Based on a patch by Niki Dokovski. (markt)
  • Fix: 58624: Correct a potential deadlock if the WebSocket connection is closed when a message write is in progress. (markt)
  • Fix: 57489: Ensure onClose() is called when a WebSocket connection is closed even if the sending of the close message fails. Includes test cases by Barry Coughlan. (markt)

Web Applications

  • Fix: 58631: Correct the continuation character use in the Windows Service How-To page of the documentation web application. (markt)
  • Fix: Correct the SSL documentation for deprecated attributes to point to the correct, new location for attributes related to individual certificates. (markt)
  • Fix: Correct some typos in the JNDI resources How-To. (markt)
  • Fix: Don't create session unnecessarily in the Manager application. (markt)
  • Fix: Don't create session unnecessarily in the Host Manager application. (markt)
  • Fix: 58723: Clarify documentation and error messages for the text interface of the manager to make clear that version must be used with path when referencing contexts deployed using parallel deployment. (markt)
  • Add: Document test.threads option in BUILDING.txt. (kkolinko)

Tribes

  • Fix: Ensure that the static member is registered to the add suspect list even if the static member that is registered to the remove suspect list has disappeared. (kfujino)
  • Fix: When using a static cluster, add the members that have been cached in the membership service to the map members list in order to ensure that the map member is a static member. (kfujino)
  • Fix: Add support for the startup notification of local members in the static cluster. (kfujino)
  • Fix: Ignore the unnecessary member remove operation from different domain. (kfujino)
  • Fix: Add support for the shutdown notification of local members in the static cluster. (kfujino)

jdbc-pool

  • Fix: Correct evaluation of system property org.apache.tomcat.jdbc.pool.onlyAttemptCurrentClassLoader. It was basically ignored before. Reported by coverity scan. (fschumacher)
  • Fix: Fix potential integer overflow in ConnectionPool and PooledConnection. Reported by coverity scan. (fschumacher)

Other

General

  • Add: Make Java 8 the minimum required version to build and run Tomcat 9. (markt)
  • Update: Remove support for Comet. (markt)
  • Update: Tighten up the default file permissions for the .tar.gz distribution so no files or directories are world readable by default. Configure Tomcat to run with a default umask of 0027 which may be overridden by setting UMASK in setenv.sh. (markt)
  • Update: Remove native code (Windows Service Wrapper, APR/native connector) support for Windows Itanium. (markt)

Catalina

  • Update: The default HTTP cookie parser has been changed to org.apache.tomcat.util.http.Rfc6265CookieProcessor. (markt)

Coyote

  • Update: Remove support for the HTTP BIO and AJP BIO connectors. (markt)
  • Code: Refactor HTTP upgrade and AJP implementations to reduce duplication. (markt)
  • Add: Add support for HPACK header encoding and decoding, contributed by Stuart Douglas. (remm)
  • Add: 57108: Add support for Server Name Indication (SNI). There has been significant changes to the SSL configuration in server.xml to support this. (markt)
  • Add: Add SSL engine for JSSE backed by OpenSSL. Includes ALPN support. Based on code contributed by Numa de Montmollin and derived from code developed by Twitter and Netty. (remm)
  • Fix: RFC 7230 states that clients should ignore reason phrases in HTTP/1.1 response messages. Since the reason phrase is optional, Tomcat no longer sends it. As a result the system property org.apache.coyote.USE_CUSTOM_STATUS_MSG_IN_HEADER is no longer used and has been removed. (markt)
  • Update: The minimum required Tomcat Native version has been increased to 1.2.2. The 1.2.x branch includes ALPN and SNI support which are required for HTTP/2. (markt)
  • Add: Add support for HTTP/2 including server push. (markt)

Tribes

  • Fix: Clarify the handling of Copy message and Copy nodes. (kfujino)

Other

  • Add: Support the use of the threads attribute on Ant's junit task. Note that using this with a value of greater than one will disable Cobertura code coverage. (markt)
