Changelog

Tomcat 10.1.19 (schultz)

Catalina

  • Fix: Correct JPMS and OSGi meta-data for tomcat-enbed-core.jar by removing reference to org.apache.catalina.ssi package that is no longer included in the JAR. Based on pull request #684 by Jendrik Johannes. (markt)
  • Fix: Fix ServiceBindingPropertySource so that trailing \r\n sequences are correctly removed from files containing property values when configured to do so. Bug identified by Coverity Scan. (markt)
  • Add: Add improvements to the CSRF prevention filter including the ability to skip adding nonces for resource name and subtree URL patterns. (schultz)
  • Fix: Review usage of debug logging and downgrade trace or data dumping operations from debug level to trace. (remm)
  • Fix: 68089: Further improve the performance of request attribute access for ApplicationHttpRequest and ApplicationRequest. (markt)
  • Fix: 68559: Allow asynchronous error handling to write to the response after an error during asynchronous processing. (markt)

Coyote

  • Fix: Setting a null value for a cookie attribute should remove the attribute. (markt)
  • Fix: Make asynchronous error handling more robust. Ensure that once a connection is marked to be closed, further asynchronous processing cannot change that. (markt)
  • Fix: Make asynchronous error handling more robust. Ensure that once the call to AsyncListener.onError() has returned to the container, only container threads can access the AsyncContext. This protects against various race conditions that woudl otherwise occur if application threads continued to access the AsyncContext.
  • Fix: Review usage of debug logging and downgrade trace or data dumping operations from debug level to trace. In particular, most of the HTTP/2 debug logging has been changed to trace level. (remm)
  • Fix: Add support for user provided SSLContext instances configured on SSLHostConfigCertificate instances. Based on pull request #673 provided by Hakan Altındağ. (markt)
  • Fix: Partial fix for 68558: Cache the result of converting to String for request URI, HTTP header names and the request Content-Type value to improve performance by reducing repeated byte[] to String conversions. (markt)
  • Fix: Improve error reporting to HTTP/2 clients for header processing errors by reporting problems at the end of the frame where the error was detected rather than at the end of the headers. (markt)
  • Fix: Remove the remaining reference to a stream once the stream has been recycled. This makes the stream eligible for garbage collection earlier and thereby improves scalability. (markt)

Jasper

  • Fix: 68546: Generate optimal size and types for JSP imports maps, as suggested by John Engebretson. (remm)
  • Fix: Review usage of debug logging and downgrade trace or data dumping operations from debug level to trace. (remm)

WebSocket

  • Fix: Allow multiple operations with the same name on introspected mbeans, fixing a regression caused by the introduction of a second addSslHostConfig method. (remm)
  • Fix: Relax the check that the HTTP Host header is consistent with the host used in the request line, if any, to make the check case insensitive since host names are case insensitive. (markt)
  • Add: 68348: Add support for the partitioned attribute for cookies including session cookies. (markt)

2021-11-15 Tomcat 10.1.0-M7 (markt)

Catalina

  • Code: Refactor HttpServlet so the default doHead() implementation now calls doGet() and relies on the container to ensure that the response body is not sent. The previous behaviour (wrapping the response) may be enabled per Servlet by setting the jakarta.servlet.http.legacyDoHead Servlet initialisation parameter to true. This aligns Tomcat with recent changes updates for Servlet 6.0 in the Jakarta Servlet specification project. (markt)

  • Fix: Fix the implementation of MethodExpression.getMethodInfo() so that it returns the expected value rather than failing when the method expression is defined with the parameter values in the expression rather than the types being passed explicitly to ExpressionFactory.createMethodExpression(). (markt)
  • Add: Add support for a new page/tag directive errorOnELNotFound that can be used to trigger an identifier if an EL expression in a page/tag contains an identifier that cannot be resolved. (markt)

2021-09-10 Tomcat 10.1.0-M5 (markt)

Catalina

  • Fix: Enable Tomcat to start if an (old) XML parser is configured that does not support allow-java-encodings. A warning will be logged if such an XML parser is detected. (markt)
  • Fix: Change the behaviour of custom error pages. If an error occurs after the response is committed, once the custom error page content has been added to the response the connection is now closed immediately rather than closed cleanly. i.e. the last chunk that marks the end of the response body is no longer sent. This acts as an additional signal to the client that the request experienced an error. (markt)
  • Fix: 65479: When handling requests using JASPIC authentication, ensure that PasswordValidationCallback.getResult() returns the result of the password validation rather than always returning false. Fixed via pull request #438 provided by Robert Rodewald. (markt)

2021-08-06 Tomcat 10.1.0-M4 (markt)

WebSocket

  • Fix: Correct a regression in the Java 8 to Java 11 changes made in 10.1.0-M3 that caused all WebSocket end points to fail to register. (markt)

not released Tomcat 10.1.0-M3 (markt)

General

  • Update: Update the minimum required Java version to Java 11. (markt)

Catalina

  • Code: Incremented the supported Jakarta Servlet version to 6.0 to align with the current development branch of the Jakarta Servlet specification. Plans have changed and the next iteration of the Servlet specification will be 6.0 rather than 5.1. (markt)
  • Fix: 65411: Always close the connection when an uncaught NamingException occurs to avoid connection locking. Submitted by Ole Ostergaard. (remm)
  • Fix: 65433: Correct a regression in the fix for 65397 where a StringIndexOutOfBoundsException could be triggered if the canonical path of the target of a symlink was shorter than the canonical path of the directory in which the symlink had been created. Patch provided by Cedomir Igaly. (markt)
  • Add: 65443: Refactor the CorsFilter to make it easier to extend. (markt)
  • Fix: To avoid unnecessary cache revalidation, do not add an HTTP Expires header when setting adding an HTTP header of CacheControl: private. (markt)
  • Code: Refactor JULI's custom LogManager, the web application class loader implementation, the web resources implementation, the JreLeakPreventionListener implementation and the StandardJarScanner implementation to remove Java 8 specific code now that the minimum Java version has been increased to 11. (markt)
  • Code: Remove all references to the endorsed standards override feature and the specifying of optional packages (extensions) in the manifest as these are not supported in Java 11. (markt)

Coyote

  • Fix: When writing an HTTP/2 response via sendfile (only enabled when useAsyncIO is true) the connection flow control window was sometimes ignored leading to various error conditions. sendfile now checks both the stream and connection flow control windows before writing. (markt)
  • Add: Add debug logging for writing an HTTP/2 response via sendfile. (markt)
  • Fix: Correct bugs in the HTTP/2 connection flow control management that meant it was possible for a connection to stall waiting for a connection flow control window update that had already arrived. Any streams on that connection that were trying to write when this happened would time out. (markt)
  • Fix: 65448: When using TLS with NIO, it was possible for a blocking response write to hang just before the final TLS packet associated with the response until the connection timed out at which point the final packet would be sent and the connection closed. (markt)
  • Fix: 65454: Fix a race condition that could result in a delay to a new request. The new request could be queued to wait for an existing request to finish processing rather than the thread pool creating a new thread to process the new request. (markt)
  • Fix: 65460: Correct a regression introduced in the previous release in the change to reduce the number of small HTTP/2 window updates sent for streams. A logic error meant that small window updates for the connection were dropped. This meant that the connection flow window slowly reduced over time until nothing could be sent. (markt)
  • Fix: Remove NIO workarounds and code that is no longer needed with Java 11. (remm)
  • Code: Refactor the endpoints to remove Java 8 specific code now that the minimum Java version has been increased to 11. (markt)

Jasper

  • Code: Add additional generics to the EL API to align with the latest changes in the EL specification project. (markt)
  • Add: Enable EL lambda expressions to be coerced to functional interfaces. This is an implementation of a proposed extension to the Jakarta Expression Language specification. (markt)
  • Code: Refactor the EL API and implementation to remove Java 8 specific code now that the minimum Java version has been increased to 11. (markt)

WebSocket

  • Code: Refactor the WebSocket implementation to remove Java 8 specific code now that the minimum Java version has been increased to 11. (markt)

Web applications

  • Fix: 65404: Correct a regression in the fix for 63362 that caused the server status page in the Manager web application to be truncated if HTTP upgrade was used such as when starting a WebSocket connection. (markt)

  • Fix: Use of GraalVM native images no longer automatically disables JMX support. JMX support may still be disabled by calling org.apache.tomcat.util.modeler.Registry.disableRegistry(). (markt)

2021-07-02 Tomcat 10.1.0-M2 (markt)

Catalina

  • Code: Refactor the RemoteIpValve to use the common utility method for list to comma separated string conversion. (markt)
  • Code: Refactor JNDIRealm$JNDIConnection so its fields are accessible to sub-classes of JNDIRealm. (markt)
  • Fix: Fix serialization warnings in UserDatabasePrincipal reported by SpotBugs. (markt)
  • Fix: 65397: Calls to ServletContext.getResourcePaths() no longer include symbolic links in the results unless allowLinking has been set to true. If a resource is skipped because of this change, a warning will be logged as this typically indicates a configuration issue. (markt)

Coyote

  • Fix: 65368: Improve handling of clean closes of inbound TLS connections. Treat them the same way as clean closes of non-TLS connections rather than as unknown errors. (markt)
  • Fix: Modify the HTTP/2 connector not to sent small updates for stream flow control windows to the user agent as, depending on how the user agent is written, this may trigger small writes from the user agent that in turn trigger the overhead protection. Small updates for stream flow control windows are now combined with subsequent flow control window updates for that stream to ensure that all stream flow control window updates sent from Tomcat are larger than overheadWindowUpdateThreshold. (markt)
  • Add: Add additional debug logging to track the current state of the HTTP/2 overhead count that Tomcat uses to detect and close potentially malicious connections. (markt)
  • Update: Many HTTP/2 requests from browsers will trigger one overhead frame and one non-overhead frame. Change the overhead calculation so that a non-overhead frame reduces the current overhead count by 2 rather than 1. This means that, over time, the overhead count for a well-behaved connection will trend downwards. (markt)
  • Update: Change the initial HTTP/2 overhead count from -10 to -10 * overheadCountFactor. This means that, regardless of the value chosen for overheadCountFactor, when a connection opens 10 overhead frames in a row will be required to trigger the overhead protection. (markt)
  • Update: Increase the default overheadCountFactor from 1 to 10 and change the reduction in overhead count for a non-overhead frame from -2 to -20. This allows for a larger range (0-20) to be used for overheadCountFactor providing for finer-grained control. (markt)
  • Fix: Modify the parsing of HTTP header values that use the 1#token to ignore empty elements as per RFC 7230 section 7 instead of treating the presence of empty elements as an error. (markt)
  • Fix: Expand the unit tests for HttpServlet.doHead() and correct the flushing of the response buffer. The buffer used to behave as if it was one byte smaller than the configured size. The buffer was flushed (and the response committed if required) when the buffer was full. The buffer is now flushed (and the response committed if required) if the buffer is full and there is more data to write. (markt)
  • Fix: Fix an issue where concurrent HTTP/2 writes (or concurrent reads) to the same connection could hang and eventually timeout when async IO was enabled (it is enabled by default). (markt)

Jasper

  • Fix: 65387: Correct a regression in the fix for 65124 and restore the local definition of out for tags that implement TryCatchFinally. (markt)
  • Fix: 65390: Correct a regression in the fix for 65124 and restore code that was removed in error leading to JSP compilation failures in some circumstances. (markt)
  • Update: Update to the Eclipse JDT compiler 4.20. (markt)
  • Add: Add support for specifying Java 17 (with the value 17) as the compiler source and/or compiler target for JSP compilation. If used with an Eclipse JDT compiler version that does not support these values, a warning will be logged and the latest supported version will used. (markt)
  • Fix: 65377: Update the Java code generation for JSPs not to use the boxed primitive constructors as they have been deprecated in Java 9 and marked for future removal in Java 16. valueOf() is now used instead. (markt)

WebSocket

  • Code: Refactor the DigestAuthenticator to reuse a shared SecureRandom instance rather than create a new one to generate the cnonce if required. (markt)

Web applications

  • Fix: 65385: Correct the link in the documentation web application the Maven Central repository. (markt)

  • Update: Simplify AprEndpoint socket bind for all platforms. (michaelo)
  • Fix: 65340: Add missing check for a negative return value for Hpack.decodeInteger in the HpackDecoder, which could cause a NegativeArraySizeException exception. Submitted by Thomas, and verified the fix is present in the donated hpack code in a further update. (remm)
  • Add: Add debug logging for HTTP/2 HPACK header decoding. (markt)
  • Fix: Correct parsing of HTTP headers consisting of a list of tokens so that a header with an empty token is treated consistently regardless of whether the empty token is at the start, middle or end of the list of tokens. (markt)
  • Fix: Remove support for the identity transfer encoding. The inclusion of this encoding in RFC 2616 was an error that was corrected in 2001. Requests using this transfer encoding will now receive a 501 response. (markt)
  • Fix: Process transfer encoding headers from both HTTP 1.0 and HTTP 1.1 clients. (markt)
  • Fix: Ensure that if the transfer encoding header contains the chunked, that the chunked encoding is the final encoding listed. (markt)
