Examples with IsLockedOperation com.hazelcast.internal.locksupport.operations.IsLockedOperation used on opensource projects

Example 1 with IsLockedOperation

use of com.hazelcast.internal.locksupport.operations.IsLockedOperation in project hazelcast by hazelcast.

the class Invocation_BlockingTest method sync_whenHeartbeatTimeout.

// ============================ heartbeat timeout =============================================================================
// 
// ===========================================================================================================================
@Test
public void sync_whenHeartbeatTimeout() {
    int callTimeout = 5000;
    Config config = new Config().setProperty(OPERATION_CALL_TIMEOUT_MILLIS.getName(), "" + callTimeout);
    TestHazelcastInstanceFactory factory = createHazelcastInstanceFactory(2);
    HazelcastInstance local = factory.newHazelcastInstance(config);
    HazelcastInstance remote = factory.newHazelcastInstance(config);
    warmUpPartitions(factory.getAllHazelcastInstances());
    NodeEngineImpl nodeEngine = getNodeEngineImpl(local);
    String key = generateKeyOwnedBy(remote);
    int partitionId = nodeEngine.getPartitionService().getPartitionId(key);
    // first we execute an operation that stall the partition.
    OperationServiceImpl opService = nodeEngine.getOperationService();
    opService.invokeOnPartition(null, new SlowOperation(5 * callTimeout), partitionId);
    // then we execute a lock operation that won't be executed because the partition is blocked.
    LockOperation op = new LockOperation(new DistributedObjectNamespace(SERVICE_NAME, key), nodeEngine.toData(key), 1, -1, -1);
    InternalCompletableFuture<Object> future = opService.createInvocationBuilder(null, op, partitionId).setCallTimeout(callTimeout).invoke();
    try {
        future.joinInternal();
        fail("Invocation should failed with timeout!");
    } catch (OperationTimeoutException expected) {
        ignore(expected);
    }
    IsLockedOperation isLockedOperation = new IsLockedOperation(new DistributedObjectNamespace(SERVICE_NAME, key), nodeEngine.toData(key), 1);
    Boolean isLocked = (Boolean) opService.createInvocationBuilder(null, isLockedOperation, partitionId).setCallTimeout(10 * callTimeout).invoke().join();
    assertFalse(isLocked);
}

Example 2 with IsLockedOperation

use of com.hazelcast.internal.locksupport.operations.IsLockedOperation in project hazelcast by hazelcast.

the class LockProxySupport method isLocked.

public boolean isLocked(NodeEngine nodeEngine, Data key) {
    IsLockedOperation operation = new IsLockedOperation(namespace, key);
    InternalCompletableFuture<Boolean> f = invoke(nodeEngine, operation, key);
    return f.joinInternal();
}
