# Changelog

Tomcat 7.0.41 (markt)

> Catalina

> > | 54703: Make parsing of HTTP Content-Type headers tolerant of any CR or LF characters that appear in the value passed by the application. Also fix some whitespace parsing issues identified by the additional test cases. (markt)
> > | Prevent possible WAR file locking when reading a context.xml file from an unexpanded WAR file. Note that in normal usage, the `JreMemoryLeakPreventionListener` would protect against this. (markt)
> > | Ensure that when auto deployment runs for a Host, it uses the latest values for copyXML, deployXML and unpackWARs. (markt)
> > | 54939: Provide logging (using a UserDataHelper) when HTTP header parsing fails (e.g. when maxHeaderCount is exceeded). (markt)
> > | 54944: Enhancements to the unit tests for FORM authentication. Patch provided by Brian Burch. (markt)
> > | 54955: When a reload of the application is performed ensure that a subsequent request to the context root does not result in a 404 response. (violetagg)
> > | 54971: Ensure that the correct location is used when writing files via `javax.servlet.http.Part.write(String)`. (markt)
> > | 54974: Ensure that `SessionCookieConfig#set<methods>` will throw `IllegalStateException` if the `ServletContext` from which this `SessionCookieConfig` was acquired has already been initialized. (violetagg)
> > | 54981: Ensure that `ServletContext#getJspConfigDescriptor()` will return `null` when there is no jsp configuration provided by web.xml/web-fragment.xml. (violetagg)
> > | Ensure that when Tomcat's anti-resource locking features are used that the temporary copy of the web application and not the original is removed when the web application stops. (markt)
> > | 54984: Use the correct encoding when processing a form data posted as multipart/form-data even when the request parameters are not parsed. (violetagg)
> > | 54999: The old JSESSIONIDSSO needs to be removed when SSO is being used and logout() and login() occur within a single request. Patch provided by Keith Mashinter. (markt)
> > | 55035: Add support for the version attribute to the deploy command of the Ant tasks for interfacing with the text based Manager application. Patch provided by Sergey Tcherednichenko. (markt)
> > | 55046: Add a Servlet Filter that implements CORS. Patch provided by Mohit Soni. (markt)
> > | 55052: JULI's LogManager now additionally looks for logging properties without prefixes if the property cannot be found with a prefix. (markt)
> > | Ensure that only the first asynchronous dispatch operation for a given asynchronous cycle will be performed. Any subsequent asynchronous dispatch operation for the same asynchronous cycle will be ignored and `IllegalStateException` will be thrown. (violetagg)

> Coyote

> > | 54947: Fix the HTTP NIO connector that incorrectly rejected a request if the CRLF terminating the request line was split across multiple packets. Patch by Konstantin Preißer. (markt)

> Jasper

> > | 54964: Allow tag plug-ins to be packaged with a web application. Patch provided by Sheldon Shao. (markt)
> > | 54968: Return the correct version number (2.2) of the JSP specification that is supported by the JSP engine when `javax.servlet.jsp.JspEngineInfo#getSpecificationVersion()` is invoked. (violetagg)

> Cluster

> > | Add `maxValidTime` attribute to prevent the leak of `FileMessageFactory` in `FarmWarDeployer`. (kfujino)
> > | Simplify the code of `ReplicationValve`: Rather than get cluster instance from container on every request, use instance variable. (kfujino)
> > | Add `maxWait` attribute that the senderPool will wait when there are no available senders. (kfujino)
> > | Improve error message by including specified timeout if failed to retrieve a data sender. (kfujino)
> > | Add `removeSuspectsTimeout` attribute in order to remove a suspect node in TcpFailureDetector. (kfujino)

> Web applications

> > | 54931: Add information to the Window Service how-to about installing and running multiple instances. Based on a patch by Chris Derham. (markt)

> Catalina

> > | Ensure a log message is generated when a web application fails to start due to an error processing a ServletContainerInitializer. (markt)
> > | Prevent NPE in JAR scanning when running in an environment where the bootstrap class loader is not an ancestor of the web application class loader such as OSGi environments. (violetagg)
> > | Ensure that, if a call to UEncoder#encodeURL is made, all internal structures are properly cleaned. (violetagg)
> > | 54660: Enable the modification of an access log's `fileDateFormat` attribute while the access log is in use. The change will take effect when the next entry is made to the access log. (markt)
> > | Update Tomcat's internal copy of Commons FileUpload to FileUpload trunk, revision 1458500 and the associated extract from Commons IO to 2.4. (markt)
> > | 54702: Prevent file descriptors leak and ensure that files are closed when parsing web application deployment descriptors. (violetagg)
> > | 54707: Further relax the parsing of DIGEST authentication headers to allow for buggy clients that quote values that RFC2617 states should not be quoted. (markt/kkolinko)
> > | Enable support for MBeans with multiple operations with the same name but different signatures. (markt)
> > | Deprecate Tomcat's internal Base 64 encoder/decoder and switch to using a package renamed copy of the Commons Codec implementation. (markt)
> > | Ensure that StandardJarScanner#scan will use the provided class loader when scanning the class loader hierarchy. (violetagg)

> Coyote

> > | 54690: Fix a regression caused by the previous fix for 54406. If no values are specified for sslEnabledProtocols or ciphers use the default values for server sockets rather than the default values for client sockets. (markt)

> Web applications

> > | Correct Deployer, Manager and Context pages of Tomcat documentation. (kkolinko)

> jdbc-pool

> > | 52318: Version for imported package `org.apache.juli.logging` is extended to include also 7.0.x versions. The fix is applicable only when running in OSGi environment. Patch provided by Martin Lichtin. (violetagg)
> > | 54599: Do not print connection password in `PoolProperties.toString()`. Based on a patch by Daniel Mikusa. (kkolinko)
> > | 54684: Add `javax.naming.spi` to `Import-Package` header in MANIFEST.MF in order to resolve `ClassNotFoundException` when running in OSGi environment. (violetagg)

> Other

> > | Update to Apache Commons Daemon 1.0.14 to resolve 54609 which meant that installation of Windows service could fail producing incorrect service launch command. (mturk)
> > | Ensure HEAD requests return the correct content length when the requested resource uses a Writer. Patch by Nick Williams. (markt)

Tomcat 7.0.38 (markt) | not released

> Catalina

> > | Ensure that the request start time (used by the access log valve to calculate request processing time) is correctly recorded for the HTTP NIO connector. In some cases the request processing time may have been longer than that recorded. (markt)
> > | Add one more library from JDK 7 to the value of `jarsToSkip` property in the `catalina.properties` file. (kkolinko)
> > | 53871: If annotation scanning results in a `StackOverflowError` due to broken class dependencies, add the class hierarchy that triggered the exception to the error message. (markt)
> > | Add a new option to the standard JarScanner implementation (`scanBootstrapClassPath`) to control if the bootstrap classpath is scanned or not. By default, it will not be scanned. (markt)
> > | Provide more consolidated servlet MBean data in the webapp MBean. (rjung)
> > | 54584: Take account of the delegate attribute when building the web application class path to pass to the JSP compiler. (markt)
> > | Copy the updated and re-packaged UTF-8 decoder from Tomcat 8.0.x and use this improved decoder for WebSocket connections. Remove the WebSocket specific UTF-8 decoder. (markt)
> > | 54602: Recycle the byte to character converter used for URIs between requests to ensure an error in one request does not trigger a failure in the next request. (markt)
> > | Use the newly added improved UTF-8 decoder for decoding UTF-8 encoded URIs and UTF-8 encoded request bodies. Invalid UTF-8 URIs will not cause an error but will make use of the replacement character when an error is detected. This will allow web applications to handle the URI which will most likely result in a 404 response. The fall-back to decoding with ISO-8859-1 if UTF-8 decoding fails has been removed. Invalid UTF-8 sequences in a request body will trigger an IOException. The way the decoder is used has also been improved. The notable change is that invalid sequences at the end of the input now trigger an error rather than being silently swallowed. (markt)
> > | 54624: Ensure that the correct request body length is used when swallowing a request body after FORM authentication prior to restoring the original request preventing possible hanging when restoring POST requests submitted over AJP. (markt)
> > | 54628: When writing binary WebSocket messages write from start position in array rather than the start of the array. Patch provided by blee. (markt)

> Coyote

> > | Refactor char encoding/decoding using NIO APIs. (remm)

> Web applications

> > | 54203: Complete the Javadoc for `javax.servlet.http.Part`. (markt)
> > | 54638: Fix display of "Used" memory value for memory pools on the status page in Manager web application when the page is rendered as XML. (kkolinko)
> > | Correct typos in configuration samples on SSL Configuration page of Tomcat documentation. (kkolinko)
> > | Disable support for comments on Changelog page of Tomcat documentation. (kkolinko)
> > | Fix several issues with `status.xsd` schema in Manager web application, testing it against actual output of StatusTransformer class. (kkolinko)
> > | Clarify the documentation on how context paths may be configured for web applications. (markt)

> Other

> > | 54601: Change `catalina.sh` to consistently use `LOGGING_MANAGER` variable to configure logging, instead of modifying `JAVA_OPTS` one. (kkolinko)

Tomcat 7.0.37 (markt) | 2013-02-18

> Catalina

> > | 54521: Ensure that concurrent requests that require a DIGEST authentication challenge receive different nonce values. (markt)
> > | 54534: Ensure that, if a call to `StandardWrapper#isSingleThreadModel()` triggers the loading of a Servlet, the correct class loader is used. (markt)
> > | 54536: Ensure the default error page is displayed if a custom HTTP status code is used when calling `HttpServletResponse#sendError(int, String)`. (markt)

> Coyote

> > | 54456: Ensure that if a client aborts a request when sending a chunked request body that this is communicated correctly to the client reading the request body. (markt)
> > | Update the native component of the APR/native connector to 1.1.27 and make that version the recommended minimum version. (markt)

> Jasper

> > | 54239: Enable web applications to provide their own Expression Language interpreter to enable them to optimise processing of expressions. Based on a patch by Sheldon Shao. (markt)

> Web applications

> Other

> > | Update to Apache Commons Daemon 1.0.13. (markt)

Tomcat 7.0.36 (markt) | not released

> Catalina

> > | Make additional allowances for buggy client implementations of HTTP DIGEST authentication. This is a follow-on to 54060. (markt)
> > | 54438: Fix a regression in the fix for 52953 that triggered a NPE when digested passwords were used and an authentication attempt was made for a user that did not exist in the realm. (markt)
> > | 54448: Correctly handle `@Resource` annotations on primitives. Patch provided by Violeta Georgieva. (markt)
> > | 54450: Correctly handle resource injection when part of the servlet properties uses `@Resource` and the other uses `injection-target`. Patch provided by Violeta Georgieva. (markt)
> > | 54458: Include exception when logging errors in the DataSourceRealm. Patch provided by Violeta Georgieva. (markt)
> > | 54483: Correct one of the Spanish translations. Based on a suggestion from adinamita. (markt)
> > | Prevent the SSO deregister when web application is stopped or reloaded. When StandardManager(pathname="") or DeltaManager stops normally, all sessions in the context are expired. In this case, because most sessions is not time-out, SSO deregister was triggered. (kfujino)
> > | Include the exception in the log message if the parsing of the context.xml file fails. (markt/kkolinko)
> > | 54497: Make memory leak detection code more robust so a failure in the leak detection code does not prevent the Context from stopping unless the error is fatal to the JVM. (markt)
> > | 54507: Do not start the background thread that is used for expiring sessions (amongst other things) until the web application is fully started. Stop the background thread as soon as the web application is stopped. (markt)
> > | Allow WebSocket Ping/Pong messages to be sent between fragments of a fragmented message. (markt)
> > | 54612: Check if the socket is closed before trying to write a WebSocket message to it. Also, flush any partial buffered data before closing the socket. (markt)

> Coyote

> > | 54324: Allow APR connector to disable TLS compression if OpenSSL supports it. (schultz)
> > | 54406: Fix NIO HTTPS connector to prune specified `ciphers` and `sslEnableProtocols` options to those supported by the SSL implementation, sharing logic with the BIO connector. Modified ciphers and sslEnabledProtocols option pruning to not silently revert to JVM defaults when none of the options specified are supported - new behaviour is to warn and explicitly enable no options. (timw)
> > | Align NIO HTTP connector with other HTTP connectors and include leading blank lines when determining the size of the HTTP headers. (markt)

> Jasper

> > | 53869: Performance improvement for pages with lots of heavily nested tags. Retain a reference to the root JSP context rather than traversing the hierarchy on every call. Based on a patch suggested by Sheldon Shao. (markt)
> > | 54440: Correct a regression caused by the changes for 54240 that broke compilation of JSPs with JspC. Patch provided by Sheldon Shao. (markt)
> > | 54466: Improve error message by including the name of the file when the java file generated from a tag file cannot be compiled. Based on a patch by Sheldon Shao. (markt)

> Cluster

> > | Fix incorrect increment of `counterSend_EVT_SESSION_EXPIRED` and `counterSend_EVT_CHANGE_SESSION_ID`. These values are not incremented if no members active in cluster group. (kfujino)
> > | 54476: Correct error in Javadoc of GroupChannel send methods to maker clear that the minimum length of the destination member array is one, not two. (markt)
> > | Prevent SSO deregister when node shutdown normally in cluster environment. (kfujino)
> > | Check cluster member before sending replicate message in ClusterSingleSignOn. (kfujino)

> Web applications

> > | 54461: Improve the documentation for the compiler attribute in the Jasper how-to. (markt)
> > | Add Jespa to the list of third-party Windows authentication providers and make external links in the documentation for those providers `no-follow`. (markt)

> Tribes

> > | 54496: Don't use a hard-coded class name in `MemberImpl.toString()`. (markt)

> Other

> > | Update to Apache Commons Daemon 1.0.12. (markt)

Tomcat 7.0.35 (markt) | 2013-01-16

> Catalina

> > | 54247: Prevent `ClassNotFoundException`s on stop when running as a service. (markt)
> > | 54249: Ensure resource properties are available when the context path contains encoded characters such as a space. This triggered compilation issues in Jasper. Patch provided by Polina Genova. (markt)
> > | 54256: Improve error reporting when a JAR file fails extension validation by including the name of the JAR file in the exception. (markt)
> > | Allow web applications to be stopped cleanly even if filters throw exceptions when their destroy() method is called. (markt/kkolinko)
> > | Fix memory leak of servlet instances when running with a SecurityManager and either init() or destroy() methods fail or the servlet is a SingleThreadModel one. (kkolinko)
> > | Cleanup method cache lookup code in `SecurityUtil` class. (kkolinko)
> > | Make the Tomcat 7 non-JSR356 WebSocket implementation non-blocking (where supported by the connector) between the HTTP upgrade and the first WebSocket message from the client to the server. (markt)
> > | 54262: Ensure that an empty `<absolute-ordering />` element in the main web.xml file disables scanning for web fragments. Based on a patch by Violeta Georgieva. (markt)
> > | 54284: As per clarification from the Servlet EG, anonymous Filters and Servlets are not permitted. Patch by Violeta Georgieva. (markt)
> > | 54371: Prevent exceptions when processing web fragments for unexpanded WAR files when the context path contains characters that need to be encoded in URLs such as spaces. Based on a patch by Polina Genova. (markt)
> > | 54372: Make HTTP Digest authentication header parsing tolerant of invalid headers sent by known buggy clients. (markt)
> > | 54377: Correctly set request attributes for AccessLog in RemoteIpFilter. Patch by Violeta Georgieva. (markt)
> > | 54379: Implement support for post-construct and pre-destroy elements in web.xml. Patch by Violeta Georgieva. (markt)
> > | 54380: Do not try to register servlets or contexts into the mapper too early (which just caused a warning to be logged). (kkolinko)
> > | Fix NPE in `WebappLoader.stopInternal` when stop is called after a failed start. (kkolinko)
> > | 54381: Add support for receiving WebSocket pong messages. (markt)
> > | 54382: Fix NPE when SSI processing is enabled and an empty SSI directive is present. (markt)
> > | Fix `ArrayIndexOutOfBoundsException` in `HttpParser` when parsing incorrect HTTP headers. (kkolinko)
> > | 54387: Deployment must fail when multiple servlets are mapped to the same url-pattern. (markt)

> Jasper

> > | 54240: Add support for auto-detection and configuration of JARs on the classpath that provide tag plug-in implementations. Based on a patch by Sheldon Shao. (markt)
> > | 54241: Revert the fix for 35410 as it was not compliant with the JSP specification, specifically that `<%= obj %>` must be translated to `out.print(obj)` which in turn becomes `out.write(String.valueOf(obj))`. This will trigger a `NullPointerException` if `obj.toString()` returns `null`. The fix for 35410 incorrectly suppressed the `NullPointerException` in this case. (markt)
> > | 54242: Correct handle null iterations with in the JSTL ForEach tag plug-in implementation. Patch provided by Sheldon Shao. (markt)
> > | 54260: Avoid `NullPointerException` when using JSP unloading and tag files. (markt)

> > | 54338: Correctly coerce the value to the expected type when using the tag plug-in for the JSTL set tag. Patch provided by Sheldon Shao. (markt)

> Web applications

> > | 54244: Clarify the documentation for the BIO and NIO SSL configuration attributes `sslEnabledProtocols` and `sslProtocol` within the documentation web application. (markt)
> > | Integrate documentation of Tomcat 7 with Apache Comments System. People can leave their comments when reading documentation online at the tomcat.apache.org site. (rjung)

> Other

> > | 54390: Use 'java_home' on Mac OS X to auto-detect JAVA_HOME. (schultz)

> > | Add support for LAST_ACCESS_AT_START system property to PersistentManager. (kfujino)
> > | Update MIME type mapping with additional / updated mime.types from the Apache web server. (markt)
> > | 54007: Fix a memory leak that prevented deletion of a context.xml file associated with a Context that had failed to deploy. Also fix the problems uncovered with undeploying such a Context once the leak had been fixed and the file could be deleted. (markt)
> > | 54044: Correct bug in timestamp cache used by logging (including the access log valve) that meant entries could be made with an earlier timestamp than the true timestamp. (markt)
> > | 54054: Do not share shell environment variables between multiple instances of the CGI servlet. (markt)
> > | 54060: Use a simple parser rather than a regular expression to parse HTTP Digest authentication headers so the header is correctly parsed. The new approach is also faster and generates less garbage. (markt)
> > | 54068: Rewrite the web fragment ordering algorithm to resolve multiple issues that resulted in incorrect ordering or failure to find a correct, valid order. (markt)
> > | The HTTP header parser added to address 52811 has been removed and replaced with the light-weight HTTP header parser created to address 54060. The new parser includes a work-around for a bug in the Adobe Acrobat Reader 9.x plug-in for Microsoft Internet Explorer that was identified when the old parser was introduced (53814).
> > | 54076: Add an alternative work-around for clients that use SPNEGO authentication and expect the authenticated user to be cached per connection (Tomcat only does this if an HTTP session is available). (markt)
> > | 54087: Correctly handle (ignore) invalid If-Modified-Since header rather than throwing an exception. (markt)
> > | 54096: In web.xml, <env-entry> should accept any type that has a constructor that takes a single String or char. (markt)
> > | 54127: Add support for sending a WebSocket Ping. Patch provided by Sean Winterberger. (markt)
> > | In FormAuthenticator: If it is configured to change Session IDs, do the change before displaying the login form. (kkolinko)
> > | Ensure `AsyncListener.timeout()` and `AsyncListener.complete()` are called with the correct thread context class loader. (fhanik)
> > | 54123: If an asynchronous request times out without any `AsyncListener`s defined, a 500 error will be triggered. (markt)
> > | 54124: Correct provided value of request attribute `javax.servlet.async.request_uri` and add missing request attribute `javax.servlet.async.path_info`. (markt)
> > | Add `denyStatus` initialization parameter to `CsrfPreventionFilter`, allowing to customize the HTTP status code used for denied requests. (kkolinko)
> > | 54141: Increase the permitted number of nested Realm levels from 2 to 3 by default and make the limit configurable via a system property. (markt)
> > | Revert occasional API change in `BaseDirContext` class that was done in 7.0.32. Methods should not be `final`. (kkolinko)
> > | Prevent failures in the AccessLogValve when running under a SecurityManager and the first request received is an asynchronous one. (markt)

> Coyote

Once deployment of a web application fails in one form (e.g. WAR), no further attempt (e.g. directory) will be made to deploy that web application. The base Lifecycle implementation has been improved to allow failed web applications to be started once the configuration issues have been resolved. Any changes to a context.xml file (global, per host or web application specific) will now result in a redeploy of the affected web application(s) that ensures that any changes are correctly applied rather than a reload which ignores changes in context.xml files.

> > | 50157: Ensure MapperListener is only added to a container object once. (markt)
> > | 50159: Add a new attribute for `<Resource>` elements, `singleton`, that controls whether or not a new object is created every time a JNDI lookup is performed to obtain the resource. The default value is `true`, which will return the same instance of the resource in every JNDI lookup. (markt)
> > | 50168: Separate the `Lifecycle.DESTROY_EVENT` into `Lifecycle.BEFORE_DESTROY_EVENT` and `Lifecycle.AFTER_DESTROY_EVENT`. Use the additional state to ensure that `Context` objects are only destroyed once. (markt)

> > | Implement support for parallel deployment. This allows multiple versions of the same web application to be deployed to the same context path at the same time. Users without a current session will be mapped to the latest version of the web application. Users with a current session will continue to use the version of the web application with which the session is associated until the session expires. (markt)
