Knopflerfish 5 released, KF moves to OSGi R5
Knopflerfish 5.0.0

Knopflerfish 5.0.0 is now officially released, the new major OSGi R5 compliant release of the leading open source based OSGi run-time for embedded use. To further emphasize the embeededness, KF5 includes a new, compact version of the OSGi R5 framework, occupying no more than 316K of disk space.

  • Fixed NPE in framework start-level controller.
19 Jun 2013
Maintenance release of Knopflerfish OSGi framework
framework 5.3.10

  • Corrected issues regarding signed bundles being incorrectly marked as not completely signed. There also seems to be a problem in the JarInputStream class implementation in Oracle JRE (Java 6 & 7). If there are user/non standard jar related files in the META-INF directory in the bundle's JAR, and they directly follow the standard META-INF signature related files, the Oracle JRE fails to find the certificates for the additional files, and KF will mark the bundle as not completely signed. Setting the property org.knopflerfish.framework.bundlestorage.file.jar_verifier_bug to true will instruct KF to assume they are properly signed.

    The versions 5.3.8 and 5.3.9 of the framework shall be regarded as intermediate releases and can be ignored as they didn't address all problems.

5 Sep 2011 Build system fix. API versions of several bundles updated.
A fix has been made in the KF build system for issue 3402741 by adding implicit imports to the API version of the bundle of all packages exported by the same bundle. The implicit import will get a version range starting with the exported version up to the next major version (excluded). This default setting is per recommendation of the OSGi Specification.

This fix affects primarily the API version of certain bundles which exports multiple packages, and previously did not explicitly import their own exported packages. The bundles listed below are all such API bundles. They have been updated to a new bug fix version (x.x.N) and are now corrected to have an implicit import of their respective exported packages.

  • Blueprint (API) 1.0.1
  • Deployment Admin (API) 1.0.2
  • DMTree 1.0.2
  • HTTP-Server 3.0.6
  • IO (API) 3.0.1
  • Log Service 3.0.6
  • User Admin 3.0.2
  • Desktop 3.1.7
  • JSDK 2.5.0.kf3-2
  • Serial Port Device 2.0.1

API bundles with a single exported package are also affected and will get the same implicit import. However the bundle version of these bundles have not been updated since this change has no real impact on such bundles.

The "_all" bundles are also affected such that they get the same version range on implicit imports. Previously they would get an implicit import with exactly the same version as the export.

The implementation versions of the bundles are not affected by this change.

15 Jul 2011 Knopflerfish 3.2 released.
