------------------------------------
Summary: InterProcessSemaphoreV2 nodes not reapable
Key: CURATOR-173
URL: https://issues.apache.org/jira/browse/CURATOR-173
Project: Apache Curator
Issue Type: Bug
Reporter: David Kesler
Assignee: Jordan Zimmerman
The curator documentation recommends using a reaper or childreaper to clean up
stale lock nodes. This worked for InterProcessSemaphore locks. However lock
paths that are created by InterProcessSemaphoreV2 cannot be reaped. The V2
recipe creates two subnodes beneath the lock node, 'locks' and 'leases', which
are never cleaned up by the recipe. This ensures that the lock node itself
will never be empty and thus never reaped. It doesn't seem like there's any
safe way of handling cleaning up after an InterProcessSemaphoreV2 using
canonical curator recipes.
