ResourceProvider registration issues: better info on duplicate, prevent loss on
registration
--------------------------------------------------------------------------------------------
Key: SLING-911
URL: https://issues.apache.org/jira/browse/SLING-911
Project: Sling
Issue Type: Bug
Components: JCR Resource
Affects Versions: JCR Resource 2.0.4
Reporter: Felix Meschberger
Assignee: Felix Meschberger
Fix For: JCR Resource 2.0.4
The resource provider registration and unregistration has some issues currently:
* Multi-threading: ResourceProvider may be registered and/or unregistered at
any time. Currently the handling of this registration or unregistration is not
done in a thread safe way. Therefore it may happen that some registrations are
lost or that some unregistrations are actually lost and do not take place.
* If a resource provider is registered for a path for which a registered
provider already exists, there is currently no information on the existing
resource provider.
This bug is about fixing these issues by synchronizing on provider registration
and unregistration and by providing a hint to the resource provider in the log
message on duplicate registrations.
