  • Update: Change the default for the enableCmdLineArguments parameter of the CGI servlet from true to false as additional hardening against CVE-2019-0232. (markt)

Coyote

  • Fix: Fix bad interaction between NIO2 async read API and the regular read. (remm)
  • Fix: Refactor NIO2 write pending strategy for the classic IO API. (remm)
  • Fix: Harmonize NIO2 isReadyForWrite with isReadyForRead code. (remm)
  • Fix: When using a JSSE TLS connector that supported ALPN (Java 9 onwards) and a protocol was not negotiated, Tomcat failed to fallback to HTTP/1.1 and instead dropped the connection. (markt)
  • Fix: Correct a regression in the TLS connector refactoring in Tomcat 9.0.17 that prevented the use of PKCS#8 private keys with OpenSSL based connectors. (markt)
  • Fix: When performing an upgrade from HTTP/1.1 to HTTP/2, ensure that any query string present in the original HTTP/1.1 request is passed to the HTTP/2 request processing. (markt)
  • Fix: When Tomcat writes a final response without reading all of an HTTP/2 request, reset the stream to inform the client that the remaining request body is not required. (markt)
  • Fix: 63312: Correct a regression in the error page handling that prevented error pages from issuing redirects or taking other action that required the response status code to be changed. (markt)

Jasper

2019-03-19 Tomcat 8.5.39 (markt)

Catalina

  • Fix: Minor HTTP/2 push fixes. (remm)
  • Fix: Refactor how cookies are transferred from the base request to a PushBuilder so that they are accessible, and may be edited, via the standard PushBuilder methods for working with HTTP headers. (markt)
  • Add: Refactor error handling to enable errors that occur before processing is passed to the application to be handled by the application provided error handling and/or the container provided error handling (ErrorReportValve) as appropriate. (markt)
  • Add: Pass 404 errors triggered by a missing ROOT web application to the container error handling to generate the response body. (markt)
  • Add: Pass 400 errors triggered by invalid request targets to the container error handling to generate the response body. (markt)
  • Add: Pass errors triggered by invalid requests or unavailable services to the application provided error handling and/or the container provided error handling (ErrorReportValve) as appropriate. (markt)
  • Code: Refactor the MBean implementations for the internal Tomcat components to reduce code duplication. (markt)
  • Update: Simplify the value of jarsToSkip property in catalina.properties file for tomcat-i18n jar files. Use prefix pattern instead of listing each language. (kkolinko)
  • Fix: Restore the getter and setter for the access log valve attribute maxLogMessageBufferSize that were accidentally removed. (markt)
  • Add: 63206: Add a new attribute to Context - createUploadTargets which, if true enables Tomcat to create the temporary upload location used by a Servlet if the location specified by the Servlet does not already exist. The default value is false. (markt)
  • Fix: 63210: Ensure that the Apache Commons DBCP 2 based default connection pool is correctly shutdown when it is no longer required. This ensures that a non-daemon thread is not left running that will prevent Tomcat from shutting down cleanly. (markt)
  • Fix: 63213: Ensure the correct escaping of group names when searching for nested groups when the JNDIRealm is configured with roleNested set to true. (markt)
  • Fix: 63236: Use String.intern() as suggested by Phillip Webb to reduce memory wasted due to String duplication. This changes saves ~245k when starting a clean installation. With additional thanks to YourKit Java profiler for helping to track down the wasted memory and the root causes. (markt)
  • Fix: 63246: Fix a potential NullPointerException when calling AsyncContext.dispatch(). (markt)

Coyote

  • Fix: Ensure that the toString(), toBytes() and toChars() methods of MessageBytes behave consistently and do not throw a NullPointerException both on newly created objects and immediately after a call to recycle(). This should not impact typical Tomcat users. It may impact users who use these classes directly in their own code. (markt)
  • Fix: When performing an HTTP/1.1 upgrade to HTTP/2 (h2c) ensure that the hostname and port from the HTTP/1.1 Host header of the upgraded request are made available via the standard methods ServletRequest.getServerName() and ServletRequest.getServerPort(). (markt)
  • Fix: Make PEM file parser a public utility class. (remm)
  • Fix: Refactor the APR/Native endpoint TLS configuration code to enable JSSE style configuration - including JKS keystores - to be used with the APR/Native connector. (markt)
  • Add: With the TLS configuration refactoring, the configuration attributes sessionCacheSize and sessionTimeout are no longer limited to JSSE implementations. They may now be used with OpenSSL implementations as well. (markt)
  • Fix: Refactor NIO2 read pending strategy for the classic IO API. (remm)
  • Fix: 63182: Avoid extra read notifications for HTTP/1.1 with NIO2 when using asynchronous threads. (remm)
  • Add: 63205: Add a work-around for a known JRE KeyStore loading bug. (markt)
  • Update: Sync with NIO2 async API from Tomcat 9 branch. (remm)
  • Fix: NIO2 should try to use SocketTimeoutException everywhere rather than a mix of it and InterruptedByTimeout. (remm)
  • Fix: Correct an error in the request validation that meant that HTTP/2 push requests always resulted in a 400 response. (markt)
  • Fix: 63223: Correctly account for push requests when tracking currently active HTTP/2 streams. (markt)
  • Fix: Verify HTTP/2 stream is still writable before assuming a timeout occurred. (remm)
  • Fix: Avoid some overflow cases with OpenSSL to improve efficiency, as the OpenSSL engine has an internal buffer. (remm)
  • Fix: Harmonize HTTP/1.1 NIO2 keepalive code. (remm)

WebSocket

  • Code: Remove the STREAMS_DROP_EMPTY_MESSAGES system property that was introduced to work-around four failing TCK tests. An alternative solution has been implemented. Sending messages via getSendStream() and getSendWriter() will now only result in messages on the wire if data is written to the OutputStream or Writer. Writing zero length data will result in an empty message. Note that sending a message via an Encoder may result in the message being send via getSendStream() or getSendWriter(). (markt)

Web applications

  • Fix: Use client's preferred language for the Server Status page of the Manager web application. Review and fix several cases when the client's language preference was not respected in Manager and Host Manager web applications. (kkolinko)
  • Fix: Fix messages used by Manager and Host Manager web applications. Disambiguate message keys used when adding or removing a host. Improve display of summary values on the status page: separate terms and values with a whitespace. Improve wording of messages for expire sessions command. (kkolinko)
  • Fix: Do not add CSRF nonce parameter and suppress Referer header for external links in Manager and Host Manager web applications. (kkolinko)

Tribes

  • Fix: Ensure that members registered in the addSuspects list are static members. (kfujino)

Other

  • Add: Expand the coverage and quality of the Russian translations provided with Apache Tomcat. (kkolinko)
  • Fix: 63041: Revert the changes for 53930 that added support for the CATALINA_OUT_CMD environment variable as they prevented correct operation with systemd configurations that did not explicitly specify a PID file. (markt)

2019-02-08 Tomcat 8.5.38 (markt)

Catalina

  • Fix: 54741: Add a new method, Tomcat.addWebapp(String,URL), that allows a web application to be deployed from a URL when using Tomcat in embedded mode. (markt)
  • Fix: Ensure that the ServletOutputStream implementation is consistent with the requirements of asynchronous I/O and that all of the write methods use a single write rather than multiple writes. (markt)
  • Fix: Correct the Javadoc for Context.getDocBase() and Context.setDocBase() and remove text that indicates that a URL may be used for the docBase as this has not been the case for quite some time. (markt)
  • Add: Ensure that Tomcat is fully terminated when running as a service. (markt)
  • Code: Treat I/O errors during request body reads the same way as I/O errors during response body writes. The errors are treated as client side errors rather than server side errors and only logged at debug level. (markt)
  • Fix: 63038: Ensure that a ClassNotFoundException is thrown when attempting to load a class from a corrupted JAR file. (markt)
  • Add: Make the removal of leading and trailing whitespace from credentials passed to BASIC authentication configurable via a new attribute, trimCredentials on the BasicAuthenticator. (markt)
  • Fix: 63003: Extend the unloadDelay attribute on a Context to include in-flight asynchronous requests. (markt)
  • Add: 63026: Add a new attribute, forceDnHexEscape, to the JNDIRealm that forces escaping in the String representation of a distinguished name to use the \nn form. This may avoid issues with realms using Active Directory which appears to be more tolerant of optional escaping when the \nn form is used. (markt)

Coyote

  • Add: 63009: Include the optional content-length header in HTTP/2 responses where an appropriate value is available. (markt)
  • Fix: 63022: Do not use the socket open state when using the wrapper isClosed method for NIO and NIO2, as it will disable all further processing. (remm)
  • Fix: Fix socket close discrepancies for NIO2, now the wrapper close is used everywhere except for socket accept problems. (remm)

Jasper

  • Fix: 63056: Correct a regression in the fix for 53737 that did not correctly scan the web application directory structure for JSPs. (markt)
  • Fix: Update the performance optimisation for using expressions in tags that depend on uninitialised tag attributes with implied scope to make the performance optimisation aware of the new public class (java.lang.Enum$EnumDesc) added in Java 12. (markt)

WebSocket

  • Fix: 57974: Ensure implementation of Session.getOpenSessions() returns correct value for both client-side and server-side calls. (markt)
  • Fix: 63019: Use payload remaining bytes rather than limit when writing. Submitted by Benoit Courtilly. (remm)
  • Fix: When running under a SecurityManager, ensure that the ServiceLoader look-up for the default javax.websocket.server.ServerEndpointConfig.Configurator implementation completes correctly rather than silently using the hard-coded fall-back. (markt)
  • Fix: Ensure that the network connection is closed if the client receives an I/O error trying to communicate with the server. (markt)
  • Fix: Ignore synthetic methods when scanning POJO methods. (markt)
  • Fix: Implement the requirements of section 5.2.1 of the WebSocket 1.1 specification and ensure that if the deployment of one Endpoint fails, no Endpoints are deployed for that web application. (markt)
  • Fix: Implement the requirements of section 4.3 of the WebSocket 1.1 specification and ensure that the deployment of an Endpoint fails if @PathParam is used with an invalid parameter type. (markt)
  • Fix: Ensure a DeploymentException rather than an IllegalArgumentException is thrown if a method annotated with @OnMessage does not conform to the requirements set out in the Javadoc. (markt)
  • Fix: Improve algorithm that determines if two @OnMessage annotations have been added for the same message type. Prior to this change some matches were missed. (markt)

Web applications

  • Fix: 63103: Remove the unused source.jsp file and associated tag from the examples web application as it is no longer used. (markt)
  • Fix: 63143: Ensure that the Manager web application respects the language preferences of the user as configured in the browser when the language of the default system locale is not English. (markt)

Tribes

  • Add: 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)
  • Update: Update the packaged version of the Tomcat Native Library to 1.2.21 to pick up the memory leak fixes when using NIO/NIO2 with OpenSSL. (markt)

Other
