(markt) Tomcat 9.0.61 (remm) Catalina Harden the CredentialHandler implementations by switching to a constant-time implementation for credential comparisons. (schultz/markt) Coyote Use a constant for the default TLS cipher suite. This will allow skipping setting it in some cases (for example, it does not make sense for OpenSSL TLS 1.3). (remm) #487: Improve logging of unknown settings frames. Pull request by Thomas Hoffmann. (remm) 65975: Add a warning if a TLS virtual host is configured with optional certificate authentication and the containing connector is also configured to support HTTP/2 as HTTP/2 does not permit optional certificate authentication. (markt) 65975: Add a warning if a TLS virtual host is configured for TLS 1.3 with a JSSE implementation and a web application is configured for CLIENT-CERT authentication. CLIENT-CERT authentication requires post-handshake authentication (PHA) when used with TLS 1.3 but the JSSE TLS 1.3 implementation does not support PHA. (markt) Improve the recycling of Processor objects to make it more robust. (markt) Jasper 65959: Serialize Function as String[] rather Class[]. (remm) Web applications 65952: Align --add-opens configuration for jsvc with the current Tomcat scripts. (markt) Correct the AJP and HTTP/1.1 Connector configuration pages in the documentation web application to show which attributes are applicable to all Connectors and which are implementation specific. (markt) Other Correct a spelling mistake in the German translations. Thanks to Thomas Hoffmann. (markt) 65951: Use the tomcat.output property for OSGi bundle manifest paths.

(markt) Update the packaged version of the Tomcat Native Library to 1.2.32 to pick up Windows binaries built with OpenSSL 1.1.1n.(markt) Improvements to Chinese translations contributed by 15625988003. (markt) Improvements to French translations. (remm) Improvements to Japanese translations contributed by tak7iji. (markt) Expand coverage of translations for jakarta.el package. Based on #488 from Volodymyr Siedlecki. (markt) 2022-03-14 Tomcat 9.0.60 (remm) Catalina 65921: The type substitution flag for the rewrite valve should set the content type for the response, not the request. (markt) #479: Enable the rewrite valve to redirect requests when the original request cannot be mapped to a context. This typically happens when no ROOT context is defined. Pull request by elkman. (markt) 65940: Fix NullPointerException if an exception occurs during the destruction of a Servlet. (markt) Coyote Fix regression introduced with 65757 bugfix which better identified non request threads but which introduced a similar problem when user code was doing sequential operations in a single thread. Test case code submitted by Istvan Szekely. (remm) Fix potential thread-safety issue that could cause HTTP/1.1 request processing to wait, and potentially timeout, waiting for additional data when the full request has been received. (markt) Throw IOException rather than IllegalStateException when the application attempts to write to an HTTP/2 stream after the client has closed the stream. (markt) Jasper When resolving methods in EL expressions that use beans and/or static fields, ensure that any custom type conversion is considered when identifying the method to call. (markt) Web applications Correct the name of the value attribute in the new documentation of OpenSSLConfCmd elements. (rjung) 2022-02-28 Tomcat 9.0.59 (remm) Catalina Add ha-api-*.jar and jaxws-rt-*.jar to the list of JARs to skip when scanning for TLDs, web fragments and annotations. (michaelo) Expand the default mappings used by ServletResponse.setLocale() to include a mapping from the ja locale to the Shift_JIS encoding. (markt) 65806: Improve the handling of session ID generation when the default algorithm for SecureRandom (SHA1PRNG) is not supported by the configured providers as will be the case for a FIPS compliant configuration. (markt) #464: Fall back to the class loader used to load JULI when the thread context class loader is not set. In a normal Tomcat configuration, this will be the system class loader. Based on a pull request by jackshirazi. (markt) #469: Include the Java Annotations API in the classes that Tomcat will not load from web applications. Pull request provided by ppkarwasz. (markt) #472: Add support for additional user attributes to TomcatPrincipal and GenericPrincipal. Patch provided by Carsten Klein. (michaelo) Fix a potential StringIndexOutOfBoundsException exception when generating a WebDAV multi-status response after an error during a copy or delete. Report the paths relative to the server root for any resources with an error. (markt) Improve the format of WebDAV XML responses to make them easier for humans to read. The change ensures that there is always a line break before starting a new element. (markt) Improve validation of the Destination header for WebDAV MOVE and COPY requests. (markt) Coyote Correct a regression in the fix for 65454 that meant that minSpareThreads and maxThreads settings were ignored when the Connector used an internal executor. (markt) 65776: Improve the detection of the Linux duplicate accept bug and reduce (hopefully avoid) instances of false positives. (markt) 65848: Revert the change that attempted to align the behaviour of client certificate authentication with NIO or NIO2 with OpenSSL for TLS between MacOS and Linux/Windows as the root cause was traced to configuration differences. (markt) #467: When system time moves backwards (e.g. after clock correction), ensure that the cached formatted current date used for HTTP headers tracks this change. Pull request provided by zhenguoli. (markt) Jasper #474: Prevent a tag file from corrupting the ELContext of the calling page. Pull request provided by Dmitri Blinov. (markt) Minor optimisation of serialization for FunctionMapperImpl in response to pull request #476. (markt) Web applications Remove the applet example from the example web application as applets are no longer supported in any major browser. (markt) Refactor a small number of pages in the examples web application to avoid an issue with reproducible builds due to differences in file ordering across different operating systems with Ant's zip task. (markt) Better documentation for the protocol attribute of the JNDIRealm. (markt) Clarify the settings described in the documentation web application to configure a cluster using static membership. (markt) Add information on the OpenSSLConf and OpenSSLConfCmd elements to the HTTP SSL configuration page in the documentation web applications. (markt) jdbc-pool Use LF line endings for text files in JARs to support reproducible builds across different operating systems. (markt) Other Switch to building with Java 11 and using --release to target Java 8. Once back-ported to all currently supported branches, this will reduce the number of Java versions developers need to juggle.

Based on #468 provided by Totoo chenyonghui. (markt) Update the OWB module to Apache OpenWebBeans 2.0.26. (remm) Revert the cherry-pick of JavaDoc fix from DBCP applied in 9.0.57 that broke the DataSourceMXBean by using a type that isn't supported by MXBeans. (markt) 2022-01-20 Tomcat 9.0.58 (remm) Coyote Correct a regression in the fix for 65785 that broke HTTP/2 server push. (markt) not released Tomcat 9.0.57 (remm) Catalina Add additional locking to DataSourceUserDatabase to provide improved protection for concurrent modifications. (markt) Add recycling check in the input and output stream isReady to try to give a more informative ISE when the facade has been recycled. (remm) Remove the deprecated JmxRemoteLifecycleListener. (markt) Make the calculation of the session storage location more robust when using file based persistent storage. (markt) Coyote 65726: Implement support for HTTP/1.1 upgrade when the request includes a body. The maximum permitted size of the body is controlled by maxSavePostSize. (markt) Restore pre-starting of minSpareThreads lost in the fix for 65454. (markt) Revert the previous fix for 65714 and implement a more comprehensive fix. (markt) 65757: Missing initial IO listener notification on Servlet container dispatch to another container thread. (remm) Expand the fix for 65757 so that rather than just checking if processing is happening on a container thread, the check is now if processing is happening on the container thread currently allocated to this request/response. (markt) Improve the fix for RST frame ordering added in 9.0.56 to avoid a potential deadlock on some systems in non-default configurations. (markt) 65767: Add support for certificates that use keys encrypted using PBES2. Based on a pull request provided by xiezhaokun. (markt) Refactor testing whether a String is a valid HTTP token. (markt) 65785: Perform additional validation of HTTP headers when using HTTP/2. (markt) When a Connector or Endpoint is paused, ensure that only new connections and new requests on existing connections are stopped while allowing in progress requests to run to completion. (markt) Explicitly release ByteBuffer instances associated with pooled channels when stopping the NioEndpoint and Nio2Endpoint. (markt) Narrow the scope of the logging of invalid cookie headers to just the invalid cookie rather than the whole cookie header. (markt) Jasper 65724: Fix missing messages for some PropertyNotWritableExceptions caused by a typo in the name used for a resource string. (markt) Add support for specifying Java 18 (with the value 18) 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 default will used. (markt) WebSocket Add support for POJO WebSocket endpoints to the programmatic upgrade that allows applications to opt to upgrade an HTTP connection to WebSocket. (markt) 65763: Improve handling of WebSocket connection close if a message write times out before the message is fully written. (markt) Other Update the OWB module to Apache OpenWebBeans 2.0.25. (remm) Update the CXF module to Apache CXF 3.5.0. (remm) Improvements to Chinese translations contributed by zhnnn. (markt) Improvements to French translations. (remm) Improvements to Japanese translations contributed by Shirayuking, yoshy and tak7iji. (markt) Improvements to Korean translations. (woonsan) Update SpotBugs to 4.5.2. (markt) Update the NSIS installer to 3.08. (markt) Update UnboundID to 6.0.3. (markt) Update CheckStyle to 9.2.1. (markt) Update BND to 6.1.0. (markt) Update OSGI annotations to 1.1.1. (markt) 2021-12-02 Tomcat 9.0.56 (remm) Catalina Make SPNEGO authentication more robust for the case where the provided credential has expired. (markt) 65684: Fix a potential NullPointerException when using JULI. (markt) Document conditions under which the AprLifecycleListener can be used to avoid JVM crashes. (michaelo) Refactor the AsyncFileHandler to reduce the possibility of log messages being lost on shutdown. (markt) Refactor the AsyncFileHandler to remove the need for the org.apache.juli.AsyncLoggerPollInterval. If set, this property now has no effect. (markt) Add debug logging to the RestCsrfPreventionFilter. Based on pull request #452 by Polina Georgieva. (markt) 65710: Implement a workaround for a JVM bug that can trigger a file descriptor leak when using multi-part upload and the application does not explicitly close an input stream for an uploaded file that was cached on disk. (markt) Coyote Improve error handling if APR/Native fails to attach TLS capabilities to a TLS enabled client connection. (markt) Improve error handling if APR/Native fails to accept an incoming connection. (markt) Provide protection against a known OS bug that causes the acceptor to report an incoming connection more than once. (markt) Avoid unnecessary duplicate read registrations for blocking I/O with the NIO connector. (markt) 65677: Improve exception handling for errors during HTTP/1.1 reads with NIO2. (markt) Refactor APR/native connector shutdown to remove a potential source of JVM crashes on shutdown when sendfile is used. (markt) When an error occurs that triggers a stream reset, ensure that the first RST frame sent to the client is the one associated with the error that triggered the reset. (markt) 65714: Fix exceptions when the security manager is enabled and the first request received after starting is an HTTP request to a TLS enabled NIO2 connector. (markt) Ensure that using NIO or NIO2 with OpenSSL for TLS behaves the same way on MacOS as it does on Linux and Windows when no trusted certificate authorities are configured and reject all client certificates. (markt) Avoid a potential deadlock during the concurrent processing of incoming HTTP/2 frames for a stream and that stream being reset. (markt) Other Switch from Cobertura to JaCoCo for code coverage as Cobertura does not support code coverage for code compiled for Java 11 onwards. It also removes the need to use a single thread to run the tests. (markt) 2021-11-10 Tomcat 9.0.55 (remm) Catalina Improve robustness of JNDIRealm for exceptions occurring when getting the connection. Also add missing close when running into issues getting the passord of a user. (remm) Add Javadoc comment which listeners must be nested whithin Server elements only. (michaelo) Add support for custom caching strategies for web application resources. This initial implementation allows control over whether or not a resource is cached. (markt) Log warning if a listener is not nested inside a Server element although it must have been. (michaelo) Coyote Improve performance of Connector shutdown - primarily to reduce the time it takes to run the test suite. (markt) Refactor the APR/native connector shutdown to reduce the possibility of a JVM crash during the connector shutdown. (markt) #457: Add a toString() method to MimeHeader to aid debugging. (dblevins) Add experimental OpenSSL support through the Panama API incubating in Java 17, with support for OpenSSL 1.1+. This no longer requires tomcat-native or APR. Please refer to the openssl-java17 module from the main branch for more details. (remm) Fix APR connector stop so it correctly waits for the sendfile thread, if any, to exit. (markt) Do not ignore the error condition if the APR connector is not able to open a server socket as continuing in this case will trigger a JVM crash. (markt) Fix a potential JVM crash when using the APR/Native connector with TLS. A crash could occur if the connector was stopped whilst a connection was performing a TLS handshake. (markt) Jasper Regenerate the EL parser using JavaCC 7.0.10. (markt) Fix a bug that prevented the EL parser correctly parsing a literal Map that used variables rather than literals for both keys and values. (markt) WebSocket Add a new method WsServerContainer.upgradeHttpToWebSocket() to align with the new method that will be available from WebSocket 2.1 onwards. (markt) Tribes #454: Differentiate warning messages in KubernetesMembershipProvider so that the missing attribute is clear to the user. PR provided by Hal Deadman. (markt) 2021-10-01 Tomcat 9.0.54 (remm) Catalina Provide the DataSource in the constructor of DataSourceUserDatabase, since it is always global. (remm) Fix delete then create object manipulations with DataSourceUserDatabase. (remm) 65553: Implement a work-around for a JRE bug that can trigger a memory leak when using the JNDI realm. (markt) 65586: Fix the bloom filter used to improve performance of archive file look ups in the web resources implementation so it works correctly for directory lookups whether or not the provided directory name includes the trailing /. (markt) #451: Improve the usefulness of the thread name cache used in JULI. Pull request provided by t-gergely. (markt) Coyote 65563: Correct parsing of HTTP Content-Range headers. Tomcat was incorrectly requiring an = character after bytes. Fix based on pull request #449 by Thierry Guérin. (markt) Correct a potential StackOverflowException with HTTP/2 and sendfile. (markt) Further improvements in the management of the connection flow control window. This addresses various bugs that caused streams to incorrectly report that they had timed out waiting for an allocation from the connection flow control window. (markt) 65577: Fix a AccessControlException reporting when running an NIO2 connector with TLS enabled. (markt) Reclassify TLS ciphers that use AESCCM8 as medium security rather than high security to align with recent changes in OpenSSL. (markt) Fix an issue that caused some Servlet non-blocking API reads of the HTTP request body to incorrectly use blocking IO. (markt) Jasper 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) WebSocket The internal upgrade handler should close the associated WebConnection on destroy. (remm) Web applications Clarify the JASPIC configuration options in the documentation web application. (markt) Other 65585: Update obsolete comments at the start of the build.properties.default file. (markt) 2021-09-10 Tomcat 9.0.53 (remm) Catalina 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) 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) 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) Refactor the authenticators to delegate the check for preemptive authentication to the individual authenticators where an authentication scheme specific check can be performed. Based on pull request #444 by Robert Rodewald. (markt) Improve the reusability of the UserDatabase by adding intermediate concrete implementation classes and allowing to do partial database updates on save. (remm) Add a UserDatabase implementation as a superset of the DataSourceRealm functionality. (remm) Make sure the dynamic Principal returned by UserDatabaseRealm stays up to date with the database contents, and add an option to have it be static, similar to the other realms. (remm) Add derby-*.jar to the list of JARs to skip when scanning for TLDs, web fragments and annotations. (markt) #447. Correct JPMS metadata for catalina.jar. Pull request provided by Hui Wang. (markt) Coyote Correct a logic error that meant setting certificateKeystoreFile to NONE did not have the expected effect. NONE was incorrectly treated as a file path. Patch provided by Mikael Sterner. (markt) 65505: When an HTTP header value is removed, ensure that the order of the remaining header values is unchanged. (markt) WebSocket 65506: Fix write timeout check that was using the read timeout value. Patch submitted by Gustavo Mahlow. (remm) Web applications Remove unnecessary Context settings from the examples web application. (markt) Document default value for unpackWARs and related clean-up. Pull request #439 provided by Robert Rodewald. (markt) Clarify the documentation of the compressionMinSize and compressibleMimeType HTTP Connector attributes. Pull request #442 provided by crisgeek. (markt) Other Fix failing build when building on non-English locales. Pull request #441 provided by Dachuan J. (markt) Update to JSign version 4.0 to enable code signing without the need for the installation of additional client tools. (markt) Update the internal fork of Apache Commons BCEL to 40d5eb4 (2021-09-01, 6.6.0-SNAPSHOT). Code clean-up only. (markt) Update the internal fork of Apache Commons Codec to fd44e6b (2021-09-01, 1.16-SNAPSHOT). Minor refactoring. (markt) Add Apache Derby 10.14.2.0 to the testsuite dependencies, for JDBC and DataSource testing. (remm) 65661: Update the internal fork of Apache Commons FileUpload to 33d2d79 (2021-09-01, 2.0-SNAPSHOT). Refactoring and code clean-up. As a result of Commons File Upload now using java.nio.file.Files, applications using multi-part uploads need to ensure that the JVM is configured with sufficient direct memory to store all in progress multi-part uploads. (markt) Update the internal fork of Apache Commons Pool to 2.11.1 (2021-08-17). Improvements, code clean-up and refactoring. (markt) Update the internal fork of Apache Commons DBCP to 2.9.0 (2021-08-03). Improvements, code clean-up and refactoring. (markt) Update the packaged version of the Tomcat Native Library to 1.2.31 to pick up Windows binaries built with OpenSSL 1.1.1l.(markt) Switch to the CDN as the primary download location for ASF dependencies. (markt) Improvements to Chinese translations contributed by syseal, wolibo, ZhangJieWen and DigitalFatCat. (markt) Improvements to Japanese translations contributed by tak7iji. (markt) Improvements to Korean translations. (woonsan) 2021-08-06 Tomcat 9.0.52 (remm) Catalina 65476: Correct an error in some code clean-up that mean that web application classes were not configured with the correct package. (markt) not released Tomcat 9.0.51 (remm) Catalina 65411: Always close the connection when an uncaught NamingException occurs to avoid connection locking. Submitted by Ole Ostergaard. (remm) 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) 65443: Refactor the CorsFilter to make it easier to extend. (markt) To avoid unnecessary cache revalidation, do not add an HTTP Expires header when setting adding an HTTP header of CacheControl: private. (markt) Coyote 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 debug logging for writing an HTTP/2 response via sendfile. (markt) 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) 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) 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) 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) Web applications 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) Other Improvements to Chinese translations contributed by ZhangJieWen and chengzheyan. (markt) Improvements to French translations. (remm) Improvements to Japanese translations contributed by tak7iji. (markt) Improvements to Korean translations. (woonsan) 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 9.0.50 (remm) Jasper Jakarta to Javax backport issue in tests. (remm) not released Tomcat 9.0.49 (remm) Catalina Refactor the RemoteIpValve to use the common utility method for list to comma separated string conversion. (markt) Refactor JNDIRealm$JNDIConnection so its fields are accessible to sub-classes of JNDIRealm. (markt) Fix serialization warnings in UserDatabasePrincipal reported by SpotBugs. (markt) 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 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) 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 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) 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) 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) 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) 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) 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 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 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 to the Eclipse JDT compiler 4.20. (markt) 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) 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 Refactor the DigestAuthenticator to reuse a shared SecureRandom instance rather than create a new one to generate the cnonce if required. (markt) Web applications 65385: Correct the link in the documentation web application the Maven Central repository. (markt) Other Update the OWB module to Apache OpenWebBeans 2.0.23. (remm) Update the CXF module to Apache CXF 3.4.4. (remm) 65369 / #422: Add the additional --add-opens=... options required for running Tomcat on Java 16 onwards to the service.bat script to align it with the other start-up scripts. PR provided by MCMicS. (markt) Update JUnit to version 4.13.2. (markt) Update EasyMock to 4.3. (markt) Update Objenesis to 3.2. (markt) Update UnboundID to 6.0.0. (markt) Update CheckStyle to 8.43. (markt) Update SpotBugs to 4.2.3. (markt) Update OSGi annotations to 1.1.0. (markt) 2021-06-15 Tomcat 9.0.48 (remm) Coyote Regression when generating reflection due to removed NIO classes in 9.0.47. (remm) Other Use JSign to integrate the build script with the code signing service to enable release builds to be created on Linux as well as Windows. (markt) not released Tomcat 9.0.47 (remm) Catalina 65301: RemoteIpValve will now avoid getting the local host name when it is not needed. (remm) 65308: NPE in JNDIRealm when no userRoleAttribute is given. (fschumacher) #412: Add commented out, sample users for the Tomcat Manager app to the default tomcat-users.xml file. Based on a PR by Arnaud Dagnelies. (markt) #418: Add a new option, pass-through, to the default servlet's useBomIfPresent initialization parameter that causes the default servlet to leave any BOM in place when processing a static file and not to use the BOM to determine the encoding of the file. Based on a pull request by Jean-Louis Monteiro. (markt) Add cookieName attribute to the SSO valve to configure the SSO cookie name. (remm) #419: When processing POST requests of type multipart/form-data for parts without a filename that are added to the parameter map in String form, check the size of the part before attempting conversion to String. Pull request provided by tianshuang. (markt) 62912: Don't mutate an application provided content header if it does not contain a charset. Also remove the outdated workaround for the buggy Adobe Reader 9 plug-in for IE. (markt) AprLifecycleListener does not show dev version suffix for libtcnative and libapr. (michaelo) Refactor principal handling in UserDatabaseRealm using an inner class that extends GenericPrincipal. (remm) Enable the default doHead() implementation in HttpServlet to correctly handle responses where the content length needs to be represented as a long since it is larger than the maximum value that can be represented by an int.

(markt) Let the RemoteCIDRValve inherit from RequestFilterValve and support all of its features. Especially add support for connector specific configuration using addConnectorPort. (rjung) Add peerAddress to coyote request, which contains the IP address of the direct connection peer. If a reverse proxy sits in front of Tomcat and the protocol used is AJP or HTTP in combination with the RemoteIp(Valve|Filter), the peer address might differ from the remoteAddress. The latter then contains the address of the client in front of the reverse proxy, not the address of the proxy itself. Support for the peer address has been added to the RemoteAddrValve and RemoteCIDRValve with the new attribute usePeerAddress. This can be used to restrict access to Tomcat based on the reverse proxy IP address, which is especially useful to harden access to AJP connectors. The peer address can also be logged in the access log using the new %{peer}a syntax. (rjung) Avoid uncaught InaccessibleObjectException on Java 16 trying to clear references threads.

(remm) Harmonize HTTP/1.1 NIO2 keepalive code. (remm) WebSocket 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().

Both now attempt to set the mappedName property of the resource. (markt) Correct the processing of resources with s defined in web.xml. First look for a match using JavaBean property names and then, only if a match is not found, look for a match using fields. (markt) When restoring a saved request with a request body after FORM authentication, ensure that calls to the HttpServletRequest methods getRequestURI(), getQueryString() and getProtocol() are not corrupted by the processing of the saved request body. (markt) JNDI resources that are defined with injection targets but no value are now treated as if the resource is not defined.

(markt) Make all loggers associated with Tomcat provided Filters non-static to ensure that log messages are not lost when a web application is reloaded. (markt) Correct the manifest for the annotations-api.jar. The JAR implements the Common Annotations API 1.3 and the manifest should reflect that. (markt) Switch to non-static loggers where there is a possibility of a logger becoming associated with a web application class loader causing log messages to be lost if the web application is stopped. (markt) 62389: Add the IPv6 loopback address to the default internalProxies regular expression. Patch by Craig Andrews. (markt) In the RemoteIpValve and RemoteIpFilter, correctly handle the case when the request passes through one or more trustedProxies but no internalProxies. Based on a patch by zhanhb.

This is a follow-up to the fix for 43925. (kkolinko/markt) Enable JspC from Tomcat 9 to work with Maven JspC compiler plug-ins written for Tomcat 8.5.x. Patch provided by Pavel Cibulka. (markt) Update web.xml, web-fragment.xml and web.xml extracts generated by JspC to use the Servlet 4.0 version of the relevant schemas. (markt) Cluster Remove duplicate calls when creating a replicated session to reduce the time taken to create the session and thereby reduce the chances of a subsequent session update message being ignored because the session does not yet exist. (markt) Add the method to send a message with a specified sendOptions. (kfujino) When sending the GET_ALL_SESSIONS message, make sure that sends with asynchronous option in order to avoid ack timeout. Waiting to receive the ALL_SESSION_DATA message should be done with waitForSendAllSessions instead of ACK. (kfujino) WebSocket Use NIO2 API for websockets writes.

(markt) 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) Coyote Avoid potential loop in APR/Native poller. (markt) Ensure streams that are received but not processed are excluded from the tracking of maximum ID of processed streams. (markt) Refactor the check for a paused connector to consistently prevent new streams from being created after the connector has been paused. (markt) Improve debug logging for HTTP/2 pushed streams. (markt) The OpenSSL engine SSL session will now ignore invalid accesses. (remm) 62177: Correct two protocol errors with HTTP/2 PUSH_PROMISE frames. Firstly, the HTTP/2 protocol only permits pushes to be sent on peer initiated requests. Secondly, pushes must be sent in order of increasing stream ID. These restriction were not being enforced leading to protocol errors at the client. (markt) Web applications Add document for FragmentationInterceptor. (kfujino) Document how the roles for an authenticated user are determined when the CombinedRealm is used.

(remm) 2018-03-08 Tomcat 9.0.6 (markt) Catalina 43866: Add additional attributes to the Manager to provide control over which listeners are called when an attribute is added to the session when it has already been added under the same name. This is to aid clustering scenarios where setAttribute() is often called to signal that the attribute value has been mutated and needs to be replicated but it may not be required, or even desired, for the associated listeners to be triggered. The default behaviour has not been changed. (markt) Minor optimization when calling class transformers. (rjung) 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.

(remm) 62000: When a JNDI reference cannot be resolved, ensure that the root cause exception is reported rather than swallowed. (markt) 62036: When caching an authenticated user Principal in the session when the web application is configured with the NonLoginAuthenticator, cache the internal Principal object rather than the user facing Principal object as Tomcat requires the internal object to correctly process later authorization checks. (markt) 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) Pass 404 errors triggered by a missing ROOT web application to the container error handling to generate the response body. (markt) Pass 400 errors triggered by invalid request targets to the container error handling to generate the response body. (markt) Provide a correct Allow header when responding to an HTTP TRACE request for a JSP with a 405 status code.

(csutherl) Ensure that the toString() method behaves consistently for ByteChunk and CharChunk and that null is returned when toString() is called 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) 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) When processing an HTTP 1.0 request in the HTTP connector and no host information is provided in the request, obtain the server port from the local port rather than the connector configuration since the configured value maybe zero. (markt) Enable strict validation of the provided host name and port for all connectors. Requests with invalid host names and/or ports will be rejected with a 400 response. (markt) Update the host validation to permit host names and components of domain names (excluding top-level domains) to start with a number and to ensure that top-level domains are fully alphabetic. (markt) 62053: Fix NPE when writing push headers with HTTP/2 NIO2. Patch submitted by Holger Sunke. (remm) Jasper Include an HTTP Allow header when a JSP generates a 405 response due to a request with an unsupported method. (markt) Add support for the HTTP OPTION method to JSPs. The JSP specification explicitly states that the behaviour for this method is undefined for JSPs so this is a Tomcat specific behaviour. (markt) WebSocket 62024: When closing a connection with an abnormal close, close the socket immediately rather than waiting for a close message from the client that may never arrive. (markt) Webapps 62049: Fix missing class from manager 404 JSP error page. (remm) jdbc-pool Enhance the JMX support for jdbc-pool in order to expose PooledConnection and JdbcInterceptors.

Patch provided by Dmitri Blinov. (markt) Add some missing NPEs to ServletContext. (remm) Update the Java EE 8 XML schema to the released versions. (markt) Minor HTTP/2 push fixes. (remm) 61916: Extend the AddDefaultCharsetFilter to add a character set when the content type is set via setHeader() or addHeader() as well as when it is set via setContentType(). (markt) When using WebDAV to copy a file resource to a destination that requires a collection to be overwritten, ensure that the operation succeeds rather than fails (with a 500 response). This enables Tomcat to pass two additional tests from the Litmus WebDAV test suite.

As part of this, provide an implementation for the B and NE flags and improve the handling for the QSA flag. Includes multiple test cases by Santhana Preethiand a patch by Tiago Oliveira. (markt) 60087: Refactor the web resources handling to use the Tomcat specific war:file:... URL protocol to refer to WAR files and their contents rather than the standard jar:file:... form since some components of the JRE, such as JAR verification, give unexpected results when the standard form is used. A side-effect of the refactoring is that when using packed WARs, it is now possible to reference a WAR and/or specific JARs within a WAR in the security policy file used when running under a SecurityManager.

(violetagg) Coyote 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) Fail earlier if the client closes the connection during SNI processing. (markt) 60123: Avoid potential threading issues that could cause excessively large values to be returned for the processing time of a current request.

(markt) 59708: Modify the LockOutRealm logic. Valid authentication attempts during the lock out period will no longer reset the lock out timer to zero. (markt) Change the default of the sessionCookiePathUsesTrailingSlash attribute of the Context element to false since the problems caused when a Servlet is mapped to /* are more significant than the security risk of not enabling this option by default. (markt) Follow-up to 59655. Improve the documentation for configuring permitted cookie names. Patch provided by Kyohei Nakamura. (markt) Do not attempt to start web resources during a web application's initialisation phase since the web application is not fully configured at that point and the web resources may not be correctly configured.

(markt) not released Tomcat 9.0.0.M7 (markt) Catalina 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) Ensure NPE will not be thrown during deployment when scanning jar files without MANIFEST.MF file. (violetagg) Remove the clearReferencesStatic option from StandardContext.

A Server header may be configured by setting the server attribute on the Connector. A new Connector attribute, serverRemoveAppProvidedValues may be used to remove any Server header set by a web application. (markt) 59564: Correct offset when reading into HTTP/2 input buffer that could cause problems reading request bodies. (violetagg/markt) Modify the handling of read/write timeouts so that the appropriate error handling (ReadListener.onError(), WriteListener.onError() or AsyncListener.onError()) is called. (markt) If an async dispatch results in the completion of request processing, ensure that any remaining request body is swallowed before starting the processing of the next request else the remaining body may be read as the start of the next request leading to a 400 response.

Unless configured otherwise, the NIO endpoint will be used by default. If SSL is configured, OpenSSL will be used rather than JSSE. (remm) Correct a regression in the fix for 58867. When configuring a Context to use an external directory for the docBase, and that directory happens to be located along side the original WAR, use the directory as the docBase rather than expanding the WAR into the appBase and using the newly created expanded directory as the docBase. (markt) 58351: Make the server build date and server version number accessible via JMX. Patch provided by Huxing Zhang. (markt) 58988: Special characters in the substitutions for the RewriteValve can now be quoted with a backslash. (fschumacher) 58999: Fix class and resource name filtering in WebappClassLoader.

(markt) Fix some resource leaks in the error handling for accessing files from JARs and WARs. (markt) Refactor the JAR and JAR-in-WAR resource handling to reduce the memory footprint of the web application. (markt) Refactor the web.xml parsing so a new parser is created every time the web application starts rather than creating and caching the parser when the Context is created. This enables the parser to take account of modified Context configuration parameters and reduces (slightly) the memory footprint of a running Tomcat instance. (markt) Switch the web application class loader to the ParallelWebappClassLoader by default. (markt) 57809: Remove the custom context attribute that held the effective web.xml. Components needing access to configuration information may access it via the Servlet API. (markt) Refactor JAR scanning to reduce memory footprint. (markt) 59001: Correctly handle the case when Tomcat is installed on a path where one of the segments ends in an exclamation mark.

(markt) 57583: Improve the performance of javax.servlet.jsp.el.ScopedAttributeELResolver when resolving attributes that do not exist. This improvement only works when Jasper is used with Tomcat's EL implementation. (markt) WebSocket Fix a timing issue on session close that could result in an exception being thrown for an incomplete message even through the message was completed. (markt) Correctly handle compression of partial messages when the final message fragment has a zero length payload. (markt) 59119: Correct read logic for WebSocket client when using secure connections. (markt) 59134: Correct client connect logic for secure connections made through a proxy. (markt) Web applications Correct an error in the documentation of the expected behaviour for automatic deployment. If a WAR is updated and an expanded directory is present, the directory will always be deleted and recreated by expanding the WAR if unpackWARs is true.

(remm) Correct an NPE when listing the enabled ciphers (e.g. via the Manager web application) for a TLS enabled APR/native connector. (markt) New configuration option ajpFlush for the AJP connectors to disable the sending of AJP flush packets. (rjung) Handle the case in the NIO connector where the required TLS buffer sizes increase after the connection has been initiated. (markt) not released Tomcat 9.0.0.M2 (markt) Catalina Refactor creation of MapperListener to ensure that the Mapper used is the Mapper associated with the Service for which the listener was created. (markt) 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) Refactor Service.getContainer() to return an Engine rather than a Container. (markt) 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) 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) 58629: Allow an embedded Tomcat instance to start when the Service has no Engine configured. (markt) Correctly notify the MapperListener associated with a Service if the Engine for that Service is changed. (markt) 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) 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) 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) 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) Correct implementation of validateClientProvidedNewSessionId so client provided session IDs may be rejected if validation is enabled. (markt) 58701: Reset the instanceInitialized field in StandardWrapper when unloading a Servlet so that a new instance may be correctly initialized. (markt) 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) Add path parameter handling to HttpServletRequest.getContextPath(). This is a follow-up to the fix for 57215. (markt) 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) 58702: Ensure an access log entry is generated if the client aborts the connection. (markt) Fixed various issues reported by Findbugs. (violetagg) 58735: Add support for the X-XSS-Protection header to the HttpHeaderSecurityFilter. Patch provided by Jacopo Cappellato. (markt) Add the StatusManagerServlet to the list of Servlets that can only be loaded by privileged applications. (markt) Simplify code and fix messages in org.apache.catalina.core.DefaultInstanceManager class. (kkolinko) 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) Ensure that the proper file encoding if specified will be used when a readme file is served by DefaultServlet. (violetagg) Fix declaration of localPort attribute of Connector MBean: it is read-only. (kkolinko) 58766: Make skipping non-class files during annotation scanning faster by checking the file name first. Improve debug logging. (kkolinko) 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) Make sure that shared Digester is reset in an unlikely error case in HostConfig.deployWAR(). (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) Remove distributable and maxInactiveInterval from the Manager interface because the attributes are never used. The equivalent attributes from the Context always take precedence. (markt) 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) 58900: Correctly undeploy symlinked resources and prevent an infinite cycle of deploy / undeploy. (markt) Coyote 58621: The certificate chain cannot be set using the main certificate attribute, so restore the certificate chain property. (remm) 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) Improve upgrade context classloader handling by using Context.bind and unbind. (remm) Improve OpenSSL keystore/truststore configuration by using the code from the JSSE implementation. (remm, jfclere) Fix a potential loop when a client drops the connection unexpectedly. (markt) OpenSSL renegotiation support for client certificate authentication. (remm) Fix NIO connector renegotiation. (remm) 58659: Fix a potential deadlock during HTTP/2 processing when the connection window size is limited. (markt) Jasper 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 handling of missing messages in org.apache.el.util.MessageFactory. (violetagg) Cluster Enable an explicit configuration of local member in the static cluster membership. (kfujino) Fix potential integer overflow in DeltaSession. Reported by coverity scan. (fschumacher) 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 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) 58624: Correct a potential deadlock if the WebSocket connection is closed when a message write is in progress. (markt) 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 58631: Correct the continuation character use in the Windows Service How-To page of the documentation web application. (markt) Correct the SSL documentation for deprecated attributes to point to the correct, new location for attributes related to individual certificates.

(markt) Document test.threads option in BUILDING.txt. (kkolinko) Tribes 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) 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) Add support for the startup notification of local members in the static cluster. (kfujino) Ignore the unnecessary member remove operation from different domain. (kfujino) Add support for the shutdown notification of local members in the static cluster. (kfujino) jdbc-pool Correct evaluation of system property org.apache.tomcat.jdbc.pool.onlyAttemptCurrentClassLoader. It was basically ignored before. Reported by coverity scan. (fschumacher) Fix potential integer overflow in ConnectionPool and PooledConnection. Reported by coverity scan. (fschumacher) Other Update optional Checkstyle library to 6.14.1.

Configure Tomcat to run with a default umask of 0027 which may be overridden by setting UMASK in setenv.sh. (markt) Remove native code (Windows Service Wrapper, APR/native connector) support for Windows Itanium. (markt) Catalina The default HTTP cookie parser has been changed to org.apache.tomcat.util.http.Rfc6265CookieProcessor. (markt) Coyote Remove support for the HTTP BIO and AJP BIO connectors. (markt) Refactor HTTP upgrade and AJP implementations to reduce duplication. (markt) Add support for HPACK header encoding and decoding, contributed by Stuart Douglas. (remm) 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 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) 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) 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 support for HTTP/2 including server push. (markt) Tribes Clarify the handling of Copy message and Copy nodes. (kfujino) Other Support the use of the threads attribute on Ant's junit task.
