-----------------------------------
Summary: [DS] Reactivate component at most once per service event
Key: FELIX-4964
URL: https://issues.apache.org/jira/browse/FELIX-4964
Project: Felix
Issue Type: Bug
Components: Declarative Services (SCR)
Affects Versions: scr-2.0.0
Reporter: David Jencks
Assignee: David Jencks
Fix For: scr-2.0.0
When a component has several references to the same service (most likely
scenario is field references for object, properties, service ref all for the
same service) and a service event results in the component being deactivated
and activated (such as a static reference being replaced by another) then we
should only reactivate the component instance once.
The solution I have in mind involves distributing events to the service
trackers for the components in a bundle through the BundleComponentActivator
and tracking the components that need to be activated with the event. Once all
the relevant service trackers have been notified, we can try to activate all
the components relevant to that service event.
