----------------------------------------
Summary: Fix GridCacheSemaphoreImpl methods semantics
Key: IGNITE-6043
URL: https://issues.apache.org/jira/browse/IGNITE-6043
Project: Ignite
Issue Type: Bug
Components: data structures
Affects Versions: 2.1
Reporter: Andrey Kuznetsov
Priority: Critical
Current semaphore implementation, {{GridCacheSemaphoreImpl}}, has inverted
method semantics: {{acquire()}} releases the permit and {{release()}} acquires
it. Also, debug-level method {{availablePermits()}} returns permits acquired so
far. This confusing behaviour should be fixed.
Also, it's worth noting in IgniteSemaphore's javadoc it's unbounded nature, as
opposed to {{java.util.concurrent.Semaphore}}.
