----------------------------------------
Summary: Prevent same configuration to be delivered multiple times
Key: FELIX-3554
URL: https://issues.apache.org/jira/browse/FELIX-3554
Project: Felix
Issue Type: Task
Components: Configuration Admin
Affects Versions: configadmin-1.2.8
Reporter: Felix Meschberger
Assignee: Felix Meschberger
Fix For: configadmin-1.6.0
It may happen, that configuration is delivered to a ManagedService[Factory]
twice depending some timing issues.
Here's the thing:
* Thread1: Configuration pid1 is created
* Thread1: ManagedServiceUpdate is scheduled (but not run yet)
* Thread1: ManagedService for pid1 is registered and configuration
provisioning scheduled (but not run yet)
* Thread2: Configuration update for pid1 is dispatched to ManagedService on
separate thread
* Thread2: ManagedService is updated with configured due to its registration
The second configuration update is not completely wrong but is not needed and
might be prevented if the configuration revision counter would be checked
before providing the configuration to the ManagedService.
