--------------------------------------------
Summary: InterProcessSemaphoreV2 leaves orphaned lease node if
acquiring the semaphore is interrupted at the wrong time
Key: CURATOR-462
URL: https://issues.apache.org/jira/browse/CURATOR-462
Project: Apache Curator
Issue Type: Bug
Components: Recipes
Affects Versions: 4.0.1, 4.0.0, 2.12.0, 3.3.0, 2.11.1, 3.2.1, 3.2.0, 2.11.0
Reporter: Gergely Krajcsovszki
Since CURATOR-315, lease nodes created in
org.apache.curator.framework.recipes.locks.InterProcessSemaphoreV2.internalAcquire1Lease(Builder<Lease>,
long, boolean, long) are not returned if the wait for them to become active is
interrupted. This is because the lease node is now only added to the builder at
the end of the method, so the caller doesn't know about this node and cannot
close it when catching an exception.
We have already fixed this locally in our own dependent library so I'll make a
PR with our fix and a test soon. We are still on the 2.x branch so we'd like if
this fix could be in 2.13.0.
