OK, thanks a lot for your quick answer.
I guess I'll have to develop a start / stop functionality into my permission manager bundle then. Do you know if this point is a deliberate choice from the specification or just an unfortunate coincidence ? I'm working with Device Services (from Device Access) and use permissions to restrict access to devices to specific applications ; restarting an application to take into account a new device is feasible yet not really convenient. regards, Pierre ________________________________ De : [email protected] [[email protected]] de la part de Thomas Watson [[email protected]] Envoyé : mardi 3 décembre 2013 15:37 À : OSGi Developer Mail List Objet : Re: [osgi-dev] Declarative Services and Conditional permission Admin There is no permissions listener to be notified when permissions change. A DS runtime is not going to notice that a service is no longer visible when permissions change. Similarly a ServiceTracker is also not going to be notified (with the adding or removed methods) that a service is now visible or not to the BundleContext used by the ServiceTracker. This means that optional non-static service dependencies will not be dynamically injected when security changes. Also, there will be issues when taking away service permissions. A component Y that got injected with service X but then later service permission for X got revoked for the bundle with the component Y will not result in unbinding the service X from component Y. If this is a concern then I think you would have to detect which bundles are using the service X and restart them to make sure they use the new permission policy.

There is a case where I'm not sure what is the expected behavior : I have a component which declares an optional and dynamic reference to a service, for which it's bundle does not have the necessary permissions : the component is activated but the service is not injected in the component (as specified in the security section of Declarative Services specifications). Now, what should happen if the permission are dynamically changed and the bundle can access the service : should the service be injected immediately (as it has the dynamic policy) ? I do not find anything in the specification about this question. This raises another question : is it possible for a bundle (SCR or not) to be notified when permissions have been changed ? Configuration Admin defines a ConfigurationListener to be notified of configuration changes, but I don't find anything similar for permissions. Any ideas about these issues ? regards, Pierre Rust _________________________________________________________________________________________________________________________ Ce message et ses pieces jointes peuvent contenir des informations confidentielles ou privilegiees et ne doivent donc pas etre diffuses, exploites ou copies sans autorisation.
