Subject [jira] [Created] (FELIX-5242) Configuration updates may be missed when the component is restarting
Date Tue, 26 Apr 2016 20:53:12 GMT
Pierre De Rop created FELIX-5242:
------------------------------------

             Summary: Configuration updates may be missed when the component is restarting
                 Key: FELIX-5242
                 URL: https://issues.apache.org/jira/browse/FELIX-5242
             Project: Felix
          Issue Type: Bug
          Components: Dependency Manager
    Affects Versions: org.apache.felix.dependencymanager-r1
            Reporter: Pierre De Rop
            Assignee: Pierre De Rop
             Fix For: org.apache.felix.dependencymanager-r9


When a component has some required dependencies, and also has a configuration dependency,
then some configuration updates may be missed in the following situation:

1) the component has lost a required dependency: it is stopped.
2) the component is restarting because the lost required dependency becomes available again.
3) at the same time, concurrently, a configuration update is taking place.

Then, during this racy condition, it is possible (but not systematically) that the component
misses the configuration update.

I have a test which demontrates this issue, as well as a patch. I will commit it soon.
