> Catalina

> > | 51249: Further improve system property replacement code in ClassLoaderLogManager of Tomcat JULI to cover some corner cases. (kkolinko)
> > | 51264: Improve the previous fix for this issue by returning the connection to the pool when not in use so it does not appear to be an abandoned connection. Patch provided by Felix Schumacher. (markt)
> > | 51324: Improve handling of exceptions when flushing the response buffer to ensure that the doFlush flag does not get stuck in the enabled state. Patch provided by Jeremy Norris. (markt)
> > | Correct a regression in the fix for 51278 that prevented any web application from being marked as distributable. (kfujino/markt)
> > | Correct a regression in the fix for 51278 that prevented a web application from overriding the default welcome files. (markt)
> > | Enable remaining valves for Servlet 3 asynchronous processing support. (markt)
> > | Avoid possible NPE when logging requests received during embedded Tomcat shutdown. (markt)
> > | 51340: Fix thread-safety issue when parsing multiple web.xml files in parallel. Apache Tomcat does not do this but products that embed it may. (markt)
> > | 51344: Fix problem with Lifecycle re-factoring for deprecated embedded class that prevented events being triggered. (markt)
> > | 51348: Prevent possible NPE when processing WebDAV locks. (markt)

> Coyote

> > | When parsing the port in the HTTP host header, treat the port as a base 10 integer rather than a hexadecimal one. (rjung/markt/kkolinko)
> > | Various refactorings to reduce code duplication and unnecessary code in the connectors. (markt)

> Jasper

> > | Change JAR scanning log messages where no TLDs are found to DEBUG level and replace the multiple messages with a single INFO level message that indicates that at least one JAR was scanned needlessly and how to obtain more info. (markt)

> > | Ensure session cookie paths end in `/` so that session cookies created for a context with a path of `/foo` do not get returned with requests mapped to a context with a path of `/foobar`. (markt)

> Jasper

> > | 51177: Ensure Tomcat's MapElResolver always returns `Object.class` for `getType()` as required by the EL specification. (markt)

Tomcat 7.0.13 (markt) | not released

> Catalina

> > | Correct mix-up in Realm Javadoc. (markt)
> > | Fix display of response headers in AccessLogValve. (kkolinko)
> > | Implement display of multiple request headers in AccessLogValve: print not just the value of the first header, but of the all of them, separated by commas. (kkolinko)

> > | Add some additional common JARs that do not contain TLDs or web fragments to the list of JARs to skip when scanning for TLDs and web fragments. (markt)
> > | While scanning JARs for TLDs and fragments, avoid using JarFile and use JarInputStream as in most circumstances where JARs are scanned, JarFile will create a temporary copy of the JAR rather than using the resource directly. This change significantly improves startup performance for applications with lots of JARs to be scanned. (markt)

> > | 51137: Add additional Microsoft Office MIME type mappings. (rjung)
> > | Partial sync of MIME type mapping with mime.types from the Apache web server. About 600 MIME types added, some changed. (rjung)
> > | Make access logging more robust when logging requests that generate 400 responses since the request object is unlikely to be fully/correctly populated in that case. (markt)

> Coyote

> > | 50957: Fix regression in HTTP BIO connector that triggered errors when processing pipe-lined requests. (markt)
> > | 50158: Ensure the asynchronous requests never timeout if the timeout is set to zero or less. Based on a patch provided by Chris. (markt)
> > | 51073: Throw an exception and do not start the APR connector if it is configured for SSL and an invalid value is provided for SSLProtocol. (markt)
> > | Align all the connector implementations with the documented default setting for processorCache of 200. This changes the default from -1 (unlimited) for the AJP-BIO, AJP-APR and HTTP-APR connectors. Additional information was also added to the documentation on how to select an appropriate value.
> > | Take account of time spent waiting for a processing thread when calculating connection and keep-alive timeouts for the HTTP BIO connector. (markt)
> > | 51095: Don't trigger a NullPointerException when the SSL handshake fails with the HTTP-APR connector. Patch provided by Mike Glazer. (markt)
> > | Improve handling in AJP connectors of the case where too large a AJP packet is received. (markt)
> > | Restore the automatic disabling of HTTP keep-alive with the BIO connector once 75% of the processing threads are in use and make the threshold configurable. (markt)
> > | Make pollerSize and maxConnections synonyms for the APR connectors since they perform the same function. (markt)
> > | Use maxThreads rather than 10000 as the default maxConnections for the BIO connectors. (markt)

> Jasper

> > | 47371: Correctly coerce the empty string to zero when used as an operand in EL arithmetic. Patch provided by gbt. (markt)
> > | Label JSP/tag file line and column numbers when reporting errors since it may not be immediately obvious what the numbers represent. (markt)
> > | Correct a regression in the fix for 49916 that resulted in JSPs being compiled twice rather than just once. (markt)
> > | Log JARs that are scanned for TLDs where no TLD is found so that users can easily identify JARs that can be added to the list of JARs to skip. (markt)
> > | Use a single TLD location cache for a web application rather than one per JSP compilation to speed up JSP compilation. (markt)
> > | 51124: Refactor BodyContentImpl to assist in determining the root cause of this bug. Based on a patch by Ramiro. (markt)

> Cluster

> > | 50950: Correct possible NotSerializableException for an authenticated session when running with a security manager. (markt)

> Web applications

> > | Configure Security Manager How-To to include a copy of the actual conf/catalina.policy file when the documentation is built, rather than maintaining a copy of its content. (kkolinko)
> > | Fix broken stylesheet URL in XML based manager status output. (rjung)
> > | 51156: Ensure session expiration option is available in Manager application was running web applications that were defined in server.xml. (markt)

> Other

> > | Clarify error messages in *.sh files to mention that if a script is not found it might be because execute permission is needed. (kkolinko)

> > | Don't unpack WAR files if they are not located in the Host's appBase. (markt)
> > | Don't log to standard out in SSLValve. (markt)
> > | Handle the case where a web crawler provides an invalid session ID in the CrawlerSessionManagerValve. (markt)
> > | Update pattern used in CrawlerSessionManagerValve to that used by the ASF infrastructure team. (markt)
> > | Remove unnecessary whitespace from MIME mapping entries in global web.xml file. (markt)
> > | When using parallel deployment, correctly handle the scenario when the client sends multiple JSESSIONID cookies. (markt)
> > | 12428: Add support (disabled by default) for preemptive authentication. This can be configured per context. Based on a patch suggested by Werner Donn. (markt)

> > | 48685: Add initial support for SPNEGO/Kerberos authentication also referred to as integrated Windows authentication. This includes user authentication, authorisation via the directory using the user's delegated credentials and exposing the user's delegated credentials via a request attribute so applications can make use of them to impersonate the current user when accessing third-party systems that use a compatible authentication mechanism. Based on a patch provided by Michael Osipov. (markt)
> > | HTTP range requests cannot be reliably served when a Writer is in use so prevent the DefaultServlet from attempting to do so. (kkolinko)
> > | Protect the DefaultServlet from Valves, Filters and Wrappers that write content to the response. Prevent partial responses to partial GET requests in this case since the range cannot be reliably determined. Also prevent the DefaultServlet from setting a content length header since this too cannot be reliably determined. (markt)

> > | Provide a configuration option that lets the close method to be used for a JNDI Resource to be defined by the user. This change also disables using the close method unless one is explicitly defined for the resource and limits it to singleton resources. (markt)
> > | Correctly track changes to context.xml files and trigger redeployment when copyXML is set to false. (markt)
> > | 50997: Relax the requirement that directories must have a name ending in `.jar` to be treated as an expanded JAR file by the default JarScanner. Based on patch by Rodion Zhitomirsky. (markt)
> > | Don't append the jvmRoute to a session ID if the jvmRoute is a zero length string. (markt)

> > | 50903: When a connector is stopped, ensure that requests that are currently in a keep-alive state and waiting for client data are not processed. Requests where processing has started will continue to completion. (markt)
> > | 50927: Improve error message when SSLCertificateFile is not specified when using APR with SSL. Based on a patch provided by sebb. (markt)
> > | 50928: Don't ignore keyPass attribute for HTTP BIO and NIO connectors. Based on a patch provided by sebb. (markt)

> Cluster

> > | Securely seed the SecureRandom instance used for UUID generation and report excessive creation time (greater than 100ms) at INFO level. (markt)

> Web applications

> > | 50924: Clean-up HTTP connector comparison table. (markt)
> > | Slightly expanded the documentation of the Host element to clarify the relationship between host name and DNS name. (markt)
> > | 50925: Update SSL how-to to take account of `keyPass` connector attribute. (markt)
> > | Improve Tomcat Logging documentation. (kkolinko)
> > | Align the authenticator documentation and MBean descriptors with the implementation. (markt)
> > | Prevent the custom error pages for the Manager and Host Manager applications from being accessed directly. (markt)
> > | 50984: When using the Manager application ensure that undeployment fails if a file cannot be deleted. (markt)

> Other

> > | 25060: Close Apache Commons DBCP datasources when the associated JNDI naming context is stopped (e.g. for a non-global DataSource resource on web application reload) to close remaining database connections immediately rather than waiting for garbage collection. (markt)
> > | 26701: Provide a mechanism for users to register their own `URLStreamHandlerFactory` objects. (markt)
> > | 50855: Fix NPE on HttpServletRequest.logout() when debug logging is enabled. (markt)
> > | New context attribute "swallowAbortedUploads" allows to make request data swallowing configurable for requests that are too large. (rjung)

> > | 21669: Add the ability to specify the roleBase for the JNDI Realm as relative to the users DN. Based on a patch by Art W. (markt)
> > | 22405: Add a new Lifecycle listener, `org.apache.catalina.security.SecurityListener` that prevents Tomcat from starting insecurely. It requires that Tomcat is not started as root and that a umask at least as restrictive as 0007 is used. This new listener is not enabled by default. (markt)

> > | Remove ServerLifecycleListener. This was already removed from server.xml and with the Lifecycle re-factoring is no longer required. (markt)
> > | Add additional checks to ensure that sub-classes of `org.apache.catalina.util.LifecycleBase` correctly implement the expected state transitions. (markt)
> > | 50189: Once the application has finished writing to the response, prevent further reads from the request since this causes various problems in the connectors which do not expect this. (markt)
> > | 50700: Ensure that the override attribute of context parameters is correctly followed. (markt)
> > | 50721: Correctly handle URL decoding where the URL ends in %nn. Patch provided by Christof Marti. (markt)
> > | 50737: Add additional information when an invalid WAR file is detected. (markt)
> > | 50748: Allow the content length header to be set up to the point the response is committed when a writer is being used. (markt)
> > | 50751: When authenticating with the JNDI Realm, only attempt to read user attributes from the directory if attributes are required. (markt)
> > | 50752: Fix typo in debug message in deprecated Embedded class. (markt)
> > | 50789: Provide an option to enable ServletRequestListeners for forwards as required by some CDI frameworks. (markt)
> > | 50793: When processing Servlet 3.0 async requests, ensure that the requestInitialized and requestDestroyed events are only fired once per request at the correct times. (markt)
> > | 50802: Ensure that `ServletContext.getResourcePaths()` includes static resources packaged in JAR files in its output. (markt)
> > | Web crawlers can trigger the creation of many thousands of sessions as they crawl a site which may result in significant memory consumption. The new Crawler Session Manager Valve ensures that crawlers are associated with a single session - just like normal users - regardless of whether or not they provide a session token with their requests. (markt)
> > | Don't attempt to start NamingResources for Contexts multiple times. (markt)
> > | 50826: Avoid `IllegalArgumentException` if an embedded Tomcat instance that includes at least one Context is destroyed without ever being started. (markt)
> > | Ensure a web application is taken out of service if the web.xml file is not valid. (kkolinko/markt)
> > | Ensure Servlet 2.2 jspFile elements are correctly converted to use a leading '/' if missing. (markt)
> > | 50836: Better documentation of the meaning of `Lifecycle.isAvailable()` and correct a couple of cases where this could incorrectly return true. (markt)

> Coyote

> > | 50780: Fix memory leak in APR implementation of AJP connector introduced by the refactoring for 49884. (markt)
> > | If server configuration errors and/or faulty applications caused the ulimit for open files to be reached, the acceptor threads for all connectors could enter a tight loop. This loop consumed CPU and also logged an error message for every iteration of the loop which lead to large log files being generated. The acceptors have been enhanced to better handle this situation. (markt)

> Jasper

> > | 50720: Ensure that the use of non-ISO-8859-1 character sets for web.xml does not trigger an error when Jasper parses the web.xml file. (markt)
> > | 50726: Ensure that the use of the genStringAsCharArray does not result in String constants that are too long for valid Java code. (markt)
> > | 50790: Improve method resolution in EL expressions. (markt)

> Cluster

> > | 50771: Ensure HttpServletRequest#getAuthType() returns the name of the authentication scheme if request has already been authenticated. (kfujino)

> Web applications
