Subject [jira] [Commented] (FELIX-3360) Bundle location is statically set for dynamically bound bundles
Date Mon, 12 Aug 2013 18:22:48 GMT

    [ https://issues.apache.org/jira/browse/FELIX-3360?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13737158#comment-13737158

David Jencks commented on FELIX-3360:

I am quite sure this is a CA problem not a DS problem.  I think Julian's patch looks like
an improvement over the current code -- setting the config's bundle location by calling getConfiguration
should be dynamic not static.  I don't know if Julian's patch is a complete solution.

> The method ConfigurationAdminImpl#getConfiguration(pid) dynamically sets the configuration's
bundle location if it is null. However, it uses ConfigurationImpl#setStaticBundleLocation(location)
in order to do so. This should be changed to set the dynamic location. Attached is a proposed
> The issue I observed, that lead me to this bug, was as follows:
> 1. Installed a number of factory configurations and the bundle (version 1.0.0, bundle
location: jcrinstall:/apps/sample/install/bundle-1.0.0.jar) providing the service implementation
(using SCR) via Sling's OSGi Installer
> 2. Uninstalled the bundle.
> 3. Installed the bundle (version 1.0.2, bundle location: jcrinstall:/apps/sample/install/bundle-1.0.2.jar)
> After this, the factory configurations were not bound to the bundle any longer, because
they were still bound to the no longer existing bundle location jcrinstall:/apps/sample/install/bundle-1.0.0.jar.
This basically leaves stale configurations and a badly configured system.
> While Sling's OSGi Installer handles updates without changing the bundle location normally,
the above scenario differs in that instead of an update, there is an uninstall + re-install
happening. The Configuration Admin Service Specification 1.3 clearly states (in 104.4.1 Location
Binding): "When this dynamically bound bundle is subsequently uninstalled, the Configuration
object's bundle location must be set to null again so it can be bound again later."
> Note: in the patch I also changed the return type of ConfigurationImpl#tryBindLocation()
from boolean to void. Before, it always returned true, so the return value is meaningless.
I almost ended up using it in an if statement because of the return type, which made me believe
that it returns true if the bundle location is set and false otherwise.
