Release Notes Knopflerfish 2.0.5 -------------------------------- Maintenance release of Knopflerfish Here follows a breakdown of the most important changes since the last release. === Framework (Core) === The default value of the system property named org.knopflerfish.servicereference.valid.during.unregistering is changed from false to true. See osgi/framework/readme.txt for details. This change is done in accordance to a clarification done by CPEG February 2008. ASM 3.1 is now used for byte code patching. New system property named org.knopflerfish.framework.debug.print_with_do_privileged If set to false debug printouts are not wrapped in doPrivileged(). See osgi/framework/readme.txt for details. === Services (Compendium) === Http Server / JSDK The JSDK bundle exports Servlet API version 2.5 (was 2.2). Note: the JSDK-bundles have been redesigned from being a LIB-bundle to an API-bundle. I.e., it does not wrap a servlet.jar-file any more, all classes are directly available inside the API-jar. This increases performance and simplifies for other bundles that needs access to the classes during their build phase. The http-server is updated to work with the version 2.5 of the Servlet API. Build files for servlet aware bundles updated to build using classes from jsdk_api-2.5.jar. Component Service Fixed a class-cast bug when loading array valued (non-String) properties from the XML document. See forum thread https://sourceforge.net/forum/forum.php?thread_id=1937504&forum_id=328005 for details. Fix issue [1895316]. Service References published by Component Service on behalf of some component where missing the component.id property. === Misc (KF specific, start scripts, build system etc === Desktop The initial directory for the add bundle dialog in the Desktop is now based on the system property "org.knopflerfish.gosg.jars" if set to a file URL, otherwise the current working directory is used. Axis-OSGi Bean-mappings for all classes used in exported, non-array valued parameters (and the return value) are now added to the WSDD generated by ObjectSOAPService for objects to export as WebServices. This will allow use of non-standard types when exporting a service as an Axis WebService. Axis2-OSGi A new bundle that exports Web Services using Axis2. This bundle is much like the axis-osgi bundle but uses Axis2 for the actual implementation. Note: Th version of the axis2-osgi bundle in this release can not be used with security enabled since it does no start then. Build System More adjustments to the build system to improve nightly- and release- builds. Documentation We have started to collect / add bundle documentation on a separate page that will be part of the release. For snapshot-builds you can find the documentation via the link http://www.knopflerfish.org/snapshots/current_trunk/bundledoc/ ======================================================================== Release Notes Knopflerfish 2.0.4 -------------------------------- Maintenance release of Knopflerfish Here follows a breakdown of the most important changes. === Framework (Core) === Added system property org.knopflerfish.framework.system.export.all If set to true the system bundle will export all standard packages provided by the JRE. The files packages.txt specifying the set of packages to export for JRE . have been moved inside framework.jar to simplify embedding. A file named packages.txt in the current working directory will override the embedded file with the same name. Added system property org.knopflerfish.framework.system.export.all_16 and a packages1.6.txt file. If this property is set to true the system bundle will export all standard packages provided by a Java SE 6 JRE. Added system property org.knopflerfish.framework.debug.service_reference If set when security is enabled, print information about service reference lookups that are rejected due to missing permissions for calling bundle. Added system property org.knopflerfish.framework.debug.bundle_resource If set when security is enabled, the framework will print information about resource lookups that are rejected due to missing permissions for the calling bundle. Fixed a bug related to bundle class paths pointing to a directory inside the bundle jar file. The manifest of the system bundle now contains the Bundle-SymbolicName header. SourceForge issue tracker id [1866116]. Fix of issue [1516267] in SourceForge issue tracker. Bundle URLConnection.getPermission() now returns AdminPermission. Added system property for debugging org.knopflerfish.framework.debug.bundle_resource if set to true all resource loading operations that fails due to missing permissions will be logged to System.out. The security policy used by the framework now delegates to the default policy for non-bundle security domains. I.e., permissions for non-bundle domains may be defined using a policy file. === Services (Compendium) === === Misc (KF specific, start scripts, build system etc === Start of the Framework The command line option "--xargs " was added. Loads the named file like "-xargs " if the file can be found, but does not abort startup of the framework if the file cannot be read. Consoletelnet The telnet console implementation now handles a missing console service by returning a message to the client saying that there is no console service available. If the console service is stopped while a telnet console session is active that session will be terminated with a message saying that the console service have been terminated. Build System Building a distribution from the top level directory places all output in the directory htdocs/releases/. New items that that are placed here: index.html file with links to all products, release note, test results, etc. Subdirectory with javadoc. Test results form the KF internal test suite. ChangeLog generated from subversion commits. Nightly builds now uses a version number that complies to the OSGi spec. Issue [1885598]. ======================================================================== Release Notes Knopflerfish 2.0.3 -------------------------------- Maintenance release of Knopflerfish Here follows a breakdown of the most important changes. === Framework (Core) === * Bug fix, Registered services are removed from the registry directly when SeriveRegistration.unregister() is called. Bundles with access to the ServiceReference for a service may get the service during the unregistering phase if the system property org.knopflerfish.servicereference.valid.during.unregistering have been set to "true" otherwise null will be returned. * Bug fix, Calling bundle.getResources(String) on the bundle object for the System bundle throws a ClassCastExcpetion. * Bundle.getResource("/") now returns a valid URL to the root of the bundle's classpath. Bundle.getResources("/") now returns an enumeration of root URLs for the bundles class path. Both these methods previously returned null when called with the argument "/". * Bug fix, Bundle.getResources(name) did not include resources from attached fragments if one or more matches was found in the bundle itself. === Services (Compendium) === * EventAdmin Updates Event class to allow for alphanumeric event topics * URLConnection Added getContentType and getContentLength * Component (Declarative Services) Corrected bugs concerning finding activate, deactivate methods defined in superclasses for Component. #1834414, === Misc (KF specific, start scritps, build system etc === * TrayIcon - WindowsVista recognized as platform alias * Junit fix (#1816102) ======================================================================== Release Notes Knopflerfish 2.0.2 -------------------------------- Maintenance release of Knopflerfish Here follows a breakdown of the most important changes. === Framework (Core) === * Bundle Class Patching New feature in KF. Bundles that contain legacy code may be cumbersome to run due to class loading problems in an OSGi environment. This new feature is based on bundle class patching using byte-code manipulation. This can solve many problems related to third-party libraries using non-OSGi compatible method calls. * Automatic Manifest Generation New feature in KF. Automatic bundle manifest generation, which can add or modify manifests to any jar file, even non-OSGi-bundle jar files. * Custom Implementation of SecurityManager no longer bypassed Changed so that a custom implementation of the SecurityManager no longer is bypassed if it is present. * Corrected bugs concerning finding resources in bundles #1741368, * Bug fix, STOPPING event is sent when stop() is called. * Corrected incorrect return value from BundleContext.ungetService(Object). See bug #1780141. === Services (Compendium) === * EventAdmin Updates Event class to allow for alphanumeric event topics * URLConnection Added getContentType and getContentLength * Component (Declarative Services) Corrected bugs concerning finding activate, deactivate methods defined in superclasses for Component. #1834414, === Misc (KF specific, start scripts, build system etc === * TrayIcon - WindowsVista recognized as platform alias * Junit fix (#1816102) ======================================================================== Release Notes Knopflerfish 2.0.1 -------------------------------- This is the first bug fix release after Knopflerfish 2.0. Here follows a breakdown of the most important changes. === Framework (R4.core) === * Boot Delegation This release includes support for the property org.osgi.framework.bootdelegation By setting this property you control what class should be loaded from the system class loader. Setting org.osgi.framework.bootdelegation to say "org.knopflerfish.*" will cause the framework to try to load all class names matching that pattern using the system class loader. If this fails the framework will try to load the class as any other class. In earlier versions the system behaved as if this property was set to "*", that is the framework all ways checked if the system class loader could load a given class. This property is set to * by default to be backward compliant. More information on this can be found in the R4 core specs section 3.8.3. * Import Resolution Optional An issue with imported packages marked as optional has been fixed. * Limitations As was the case in 2.0, all OSGi R4 features except those listed below are implemented: * Signed bundles are not supported yet. * Conditional Permission Admin is not included. To use the extension bundle support you need to use a wrapper script that will restart framework when needed. An example shell-script is included (osgi/kf2). === Services (R4.cmpn) === * User Admin service Added persistence. The path to the file where user admin data is stored can be set with the system property org.knopflerfish.useradmin.store If this is not set, the bundle's data storage area is used, meaning that starting the platform with -init purges the data. One can also use the system property org.knopflerfish.useradmin.oldstore to define a path that is used to read the data if the org.knopflerfish.useradmin.store property is set to a path that does not exist yet. This can be used to move the store to a new location. The persistence can be turned off by setting the system property org.knopflerfish.useradmin.dontsave to true. * Declarative services Fixed a bug where, under certain circumstances, null was passed to bind/unbind methods.
