Release Notes Knopflerfish 3.1.0 (OSGi R4 v4.2)
--------------------------------------------------
Maintenance release of Knopflerfish available from
http://www.knopflerfish.org/releases/3.1.0
Here follows a breakdown of the most important changes since the
last release.
=== Framework (Core) ===
Framework 5.1.6
- Always wait for stop operations to complete before continuing.
- Fixed bug with call to removed a removed service listener.
- Fixed race conditions in StartLevel-service and Bundle.getHeaders().
- Fixed bug when shutting down a framework running at start level 1.
- Fixed IllegalArgumentException for StartLevel-service.
- Add threaded handling of listeners, this means that asynchronous listeners
will be called asynchronously. The number of threads used is controlled via
the property, org.knopflerfish.framework.listener.n_threads. Default value
is 1. If the value is 0 then we will revert to the old behavior and call
all listeners synchronously. Also fixed some minor bugs that was revealed
during the testing of the new listener handling.
- Use system properties to set default values for OSGi framework properties.
- Recognize deprecated processor value "arm" in native code matching.
- Fixed locking problem when stopping a crashed bundle.
- Fixed NPE when unregistering URLStreamHandlerService.
- Fixed getEntry() method for system bundle. The result will
vary depending on the JVM since we use getResource() via the
framework class loader.
- Fixed handling of none null boot-classloader.
- Fixed bug in lazy activation class filtering.
- Fixed handling of org.osgi.framework.storage property on command line.
- Merged fix of class loader problem when running on Android 7/8 from
the kf_2_support branch. The boot-classloader of Android does not
return the expected null as its parent class loader, it returns
itself.
=== Services (Compendium) ===
Event 3.0.4
- Fixed infinite loop when debug logging was enabled for event admin.
Deploymentadmin 1.0.1
- The version of the "org.osgi.service.deploymentadmin.spi"-package
that this bundle exports was wrong, for OSGi R4 v4.2 the version
should be 1.0.1 and nothing else. Note that it was only the
version stated in the Export-Package header that was wrong.
Dmtree 1.0.1
- The version of the "org.osgi.service.dmtree"-package
that this bundle exports was wrong, for OSGi R4 v4.2 the version
should be 1.0.1 and nothing else. Note that it was only the
version stated in the Export-Package header that was wrong.
- This bundle must use dynamic import package "*" to allow a bundle
to provide the digest class specified by the system property
"org.osgi.vendor.dmtree.DigestDelegate".
HTTP-Server 3.0.1
- The version of the "org.osgi.service.http"-package that this
bundle exports was wrong, for OSGi R4 v4.2 the version should be
1.2.1 and nothing else. Note that it was only the version stated
in the Export-Package header that was wrong.
Log 3.0.5
- Fix NPE in 3.0.4. Register ManagedService with a PID that matches
configuration meta data. LogRef now handles calls to the
log()-methods occurring after the bundle it logs for have been
stopped.
- Clean up old broken Java-Doc comments and remove a potential
problem with synchronization on non-final variables.
- Use a cache to avoid recomputing the log-level for a bundle for
each entry it sends to the logs.
- Resolved some dead-locks and NullPointerExceptions occurring during
shut-down that was made visible by the listener handling changes
in the v 5.1 of the framework.
Measurement 3.0.1
- The version of the "org.osgi.util.measurement"-package that this
bundle exports was wrong, for OSGi R4 v4.2 the version should be
1.0.1 and nothing else. Note that it was only the version stated
in the Export-Package header that was wrong.
Position 3.0.1
- The version of the "org.osgi.util.position"-package that this
bundle exports was wrong, for OSGi R4 v4.2 the version should be
1.0.1 and nothing else. Note that it was only the version stated
in the Export-Package header that was wrong.
Prefs (OSGi Preferences Service) 3.0.1
- The version of the "org.osgi.service.prefs"-package that this
bundle exports was wrong, for OSGi R4 v4.2 the version should be
1.1.1 and nothing else. Note that it was only the version stated
in the Export-Package header that was wrong.
Xml 3.0.1
- The version of the "org.osgi.util.xml"-package that this
bundle exports was wrong, for OSGi R4 v4.2 the version should be
1.0.1 and nothing else. Note that it was only the version stated
in the Export-Package header that was wrong.
Kf_metatype 3.0.1
- Made bundle listeners synchronous, so that we always have
the correct state of the metatype information.
=== Misc (KF specific, start scripts, build system etc) ===
Bundlerepository 3.1.2
- Use "http://www.knopflerfish.org/releases/current-kf_3/repository.xml"
as the default repository URL for non-release builds. Release
builds will use the repository of that release.
Desktop 3.1.5
- Ensure that all code handles a null PackageAdmin-service object.
- When the path from the property "org.knopflerfish.gosg.jars"
contains more than one element, use the first one that exists as
the starting directory of the install bundle dialog.
- Removed some NullPointerExceptions during shut-down that was made
visible by the listener handling changes in v 5.1 of the framework.
- The version of the "org.osgi.service.cm"-package
that this bundle re-exports was wrong, for OSGi R4 v4.2 the version
should be 1.3.0 and nothing else. Note that it was only the
version stated in the Export-Package header that was wrong.
- The version of the "org.osgi.service.event"-package
that this bundle re-exports was wrong, for OSGi R4 v4.2 the version
should be 1.2.0 and nothing else. Note that it was only the
version stated in the Export-Package header that was wrong.
- The version of the "org.osgi.service.prefs"-package
that this bundle re-exports was wrong, for OSGi R4 v4.2 the version
should be 1.1.1 and nothing else. Note that it was only the
version stated in the Export-Package header that was wrong.
- Fixed a dead-lock problem caused by a bundle listener that did
call-backs to the framework on the event delivery thread which a
framework implementation does not need to support.
- The large icons displayer now scrolls to make new bundles visible
again.
- The set of selected bundles no longer changes when a bundle is
started, stopped, updated, refreshed. The problem was caused by
the bundle details displayer that fired to coarse table model
change events when receiving bundle change events from the
framework, causing the underlying swing table model to clear all
selections.
FW-Tray 3.0.2
- A class loader may throw a NoClassDefFoundError when it fails to
define a class since some class that the class to be loaded needs
are missing. Changed the tray icon bundle to handle this, i.e., it
now catches Throwable and not just Exception when trying to
instantiate java.awt.SystemTray.
Xalan 2.7.1.kf3_01
- Set export and import versions of javax.xml.* packages so that
it works together with the Xerxes bundle.
Build System
- The "Bundle" task now uses the version from the "packageinfo"-file
when generating the export packages header.
- bundlebuidl.xml did not create an Export-Package header for
impl-bundles that specified an "impl-api.pattern".
- The BundleInfoTask now assigns versions to exported packages based
on the version specified in the "packageinfo"-file in the
directory that holds the classes of the package. The build will
fail if there is a miss-match between the version given in the
template manifest and the version in the "packageinfo"-file.
- bundlebuild.xml now copies resources from the source tree to the
classes tree in the compile step. The internal target that added
resources from the source tree to the bundle jar file has been
removed since those resources are added to the jar
