> InterProcessMutex doesn't clean up after interrupt
> --------------------------------------------------

> Key: CURATOR-79
> URL: https://issues.apache.org/jira/browse/CURATOR-79
> Project: Apache Curator
> Issue Type: Bug
> Affects Versions: 2.0.0-incubating, 2.1.0-incubating, 2.2.0-incubating,
> 2.3.0
> Reporter: Orcun Simsek
> Assignee: Jordan Zimmerman
> Fix For: 2.7.0
>
>
> InterProcessMutex can deadlock if a thread is interrupted during acquire().
> Specifically, CreateBuilderImpl.pathInForeground submits a create request to
> ZooKeeper, and an InterruptedException is thrown after the node is created in
> ZK but before ZK.create returns. ZK.create propagates a non-KeeperException,
> so Curator assumes the create has failed, but does not retry, and the node is
> now orphaned. At some point in the future, the node becomes the next in the
> acquisition sequence, but is not reclaimed as the ZK session has not expired.
> <stack trace attached in comments below>
> Curator should catch the InterruptedException and other non-KeeperExceptions,
> and delete the created node before propagating these exceptions.
