Changelog

Tomcat 7.0.93 (violetagg)
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)
add 62897: Provide a property (clearReferencesThreadLocals) on the standard Context implementation that enables the check for memory leaks via ThreadLocals to be disabled because this check depends on the use of an API that has been deprecated in later versions of Java. (markt)
fix 62978: Update the RemoteIpValve to handle multiple values in the x-forwarded-proto header. Patch provided by Tom Groot. (markt)
fix Update the RemoteIpFilter to handle multiple values in the x-forwarded-proto header. Based on a patch provided by Tom Groot. (markt)
code 62986: Refactor the code that performs class scanning during web application start to make integration simpler for downstream users. Based on a patch provided by rmannibucau. (markt)
fix Implement the requirements of section 8.2.2 2c of the Servlet specification and prevent a web application from deploying if it has fragments with duplicate names and is configured to use relative ordering of fragments. (markt)
update Update the recommended minimum Tomcat Native version to 1.2.19. (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)
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)
update Update the recommended minimum Tomcat Native version to 1.2.21. (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)
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)
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 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)
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)
Other

update Update the packaged version of the Tomcat Native Library to 1.2.19 to pick up the latest Windows binaries built with APR 1.6.5 and OpenSSL 1.1.1a. (markt)
fix Correct AsyncFileHandler to FileHandler in logging.properties. (huxing)
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)
fix Enable compilation and test execution with Java 11. Note that the deprecated class org.apache.catalina.util.Base64 will be excluded from the build in this case as it depends on JRE classes that have been removed in Java 11 onwards. (markt)
update Update the NSIS Installer used to build the Windows installer to version 3.04. (markt)
add Expand the coverage and quality of the Russian translations provided with Apache Tomcat. (kkolinko)

fix Implement the requirements of RFC 7230 that any HTTP/1.1 request that specifies a host in the request line, must specify the same host in the Host header and that any such request that does not, must be rejected with a 400 response. This check is optional and disabled by default. It may be enabled with the allowHostHeaderMismatch attribute of the Connector. (markt)
fix Implement the requirements of RFC 7230 that any HTTP/1.1 request that contains multiple Host headers is rejected with a 400 response. (markt)
