Example 6 with ISemaphore

use of com.hazelcast.cp.ISemaphore in project hazelcast by hazelcast.

the class AbstractSemaphoreFailureTest method testAcquireOnMultipleProxies.

@Test
public void testAcquireOnMultipleProxies() {
    HazelcastInstance otherInstance = instances[0] == proxyInstance ? instances[1] : instances[0];
    ISemaphore semaphore2 = otherInstance.getCPSubsystem().getSemaphore(semaphore.getName());
    semaphore.init(1);
    semaphore.tryAcquire(1);
    assertFalse(semaphore2.tryAcquire());
}

Example 7 with ISemaphore

use of com.hazelcast.cp.ISemaphore in project hazelcast by hazelcast.

the class SemaphoreLongAwaitTest method testLongAwait.

private void testLongAwait(HazelcastInstance instance) throws ExecutionException, InterruptedException {
    ISemaphore semaphore = instance.getCPSubsystem().getSemaphore(proxyName);
    Future<Object> f1 = spawn(() -> {
        if (!semaphore.tryAcquire(1, 5, TimeUnit.MINUTES)) {
            throw new IllegalStateException();
        }
        semaphore.release();
        return null;
