Catalina
  • 58590: Add the ability for a UserDatabase to monitor the backing XML file for changes and reload the source file if a change in the last modified time is detected. This is enabled by default meaning that changes to $CATALINA_BASE/conf/tomcat-users.xml will now take effect a short time after the file is saved. (markt)
  • 61171: Add the portOffset attribute to the Server element which is added to the configured shutdown and Connector ports. Based on a patch by Marek Czernek. (markt)
  • 61692: Add the ability to control which HTTP methods are handled by the CGI Servlet via a new initialization parameter cgiMethods. (markt)
  • 62687: Expose content length information for resources when using a compressed war. (remm)
  • 62737: Fix rewrite substitutions parsing of {} nesting. (remm)
  • Add rewrite flags output when getting the rewrite configuration back. (remm)
  • Add missing qsdiscard flag to the rewrite flags as a cleaner way to discard the query string. (remm)
  • 62755: Add ability to opt out of adding the default web.xml config when embedding Tomcat and adding a context via addWebapp(). CallsetAddDefaultWebXmlToWebapp(false) to prevent the automatic config. (isapir)
  • Add documentation about the files context.xml.default and web.xml.default that can be used to customize conf/context.xml and conf/web.xml on a per host basis. (fschumacher)
  • Ensure that a canonical path is always used for the docBase of a Context to ensure consistent behaviour. (markt)
  • 62803: Fix SSL connector configuration processing in storeconfig. (remm)

  • 62802: Restore the appContextProtection attribute to the JreMemoryLeakPreventionListener as application code may still trigger this memory leak. (markt)
  • 62809: Correct a regression in the implementation of DIGEST authentication support for the Deployer Ant tasks (bug 45832) that prevented the DeployTask from working when authentication was required. (markt)
  • Update the recommended minimum Tomcat Native version to 1.2.18. (markt)
  • Ignore an attribute named source on Context elements provided by StandardContext. This is to suppress warnings generated by the Eclipse / Tomcat integration provided by Eclipse. Based on a patch by mdfst13. (markt)
  • 62830: Added JniLifeCycleListener and static methods Library.loadLibrary(libraryName) and Library.load(filename) to load a native library by a shared class loader so that more than one Webapp can use it. (isapir)
  • Refactor the Connector so that the port is obtained from the Endpoint rather than a local field that could end up out of sync. (markt)
  • Add EncryptInterceptor to the portfolio of available clustering interceptors. This adds symmetric encryption of session data to Tomcat clustering regardless of the type of cluster manager or membership being used. (schultz)
  • Correct a typo in the Spanish resource files. Patch provided by Diego Agulló. (markt)
  • 62868: Order the Enumeration<URL> provided by WebappClassLoaderBase.getResources(String) according to the setting of the delegate flag. (markt)

  • 62748: Add TLS 1.3 support for the APR/Native connector and the NIO/NIO2 connector when using the OpenSSL backed JSSE implementation. (schultz/markt)
  • 62791: Remove an unnecessary check in the NIO TLS implementation that prevented from secure WebSocket connections from being established. (markt)
  • Fix server initiated TLS renegotiation to obtain a client certificate when using NIO/NIO2 and the OpenSSL backed JSSE TLS implementation. (markt)
  • Ensure open sockets etc. are cleaned up if the socket binding process fails. (markt)
  • 62871: Improve MBeans for Endpoint instances (type ThreadPool in JMX) by using explicit declaration of attributes and operations rather than relying on introspection. Add a new MBean to expose the Socketproperties values. (markt)
Jasper
  • Correct parsing of XML whitespace in TLD function signatures that incorrectly only looked for the space character. (markt)
  • 62674: Correct a regression in the stand-alone JSP compiler utility, JspC, caused by the fix for 53492, that caused the JSP compiler to hang. (markt)
  • 62721: Correct generation of web.xml header when using JspC. (markt)
  • 62757: Correct a regression in the fix for 62603 that caused NullPointerExceptions when compiling tag files on first access when development mode was disabled and background compilation was enabled. Based on a patch by Jordi Llach. (markt)
WebSocket
  • 62731: Make the URI returned by HandshakeRequest.getRequestURI() and Session.getRequestURI() absolute so that the scheme, host and port are accessible. (markt)
Web applications
  • 62676: Expand the CORS filter documentation to make it clear that explicit configuration is required to enable support for cross-origin requests. (markt)
  • 62712: Correct NPE in Manager application when attempting to view configured certificates for an APR/native TLS connector. (markt)
  • 62761: Correct the advanced CORS example in the Filter documentation to use a valid configuration. (markt)
  • 62786: Add a note to the Context documentation to explain that, by default, settings for a Context element defined in server.xml will be overwritten by settings specified in a default context file such as conf/context.xml. (markt)
  • Create a little visual separation between the Undeploy button and the other buttons in the Manager application. Patch provided by Łukasz Jąder. (markt)
Tribes

  • Experimental Kubernetes aware cloud membership provider, based on code by Maxime Beck. Contains code derived from jgroups. (remm/kfujino)
  • Move the event notification ThreadPoolExecutor to MembershipProviderBase. (kfujino)
  • Even if all members have already disappeared and PING can not be sent, ensure that members will be expired. (kfujino)

  • 62258: Don't trigger the standard error page mechanism when the error has caused the connection to the client to be closed as no-one will ever see the error page. (markt)
  • Register MBean when DataSource Resource type="javax.sql.XADataSource". Patch provided by Masafumi Miura. (csutherl)
  • Fix a rare edge case that is unlikely to occur in real usage. This edge case meant that writing long streams of UTF-8 characters to the HTTP response that consisted almost entirely of surrogate pairs could result in one surrogate pair being dropped. (markt)
  • Update the internal fork of Apache Commons BCEL to r1829827 to add early access Java 11 support to the annotation scanning code. (markt)
  • 62297: Enable the CrawlerSessionManagerValve to correctly handle bots that crawl multiple hosts and/or web applications when the Valve is configured on a Host or an Engine. (fschumacher)

Jasper
