Francesco Nigro created CURATOR-595:
---------------------------------------
Summary: InterProcessSemaphoreV2 LOST isn't releasing permits for
other clients
Key: CURATOR-595
URL: https://issues.apache.org/jira/browse/CURATOR-595
Project: Apache Curator
Issue Type: Bug
Components: Recipes
Affects Versions: 5.1.0
Reporter: Francesco Nigro
I'm not sure this is the right place to raise this, but I've added this test on
{quote}TestInterProcessSemaphore{quote}:
{code:java}
@Test
public void testAcquireAfterLostServerOnRestart() throws Exception {
final int sessionTimout = 2000;
final int connectionTimout = 4000;
try (CuratorFramework client =
CuratorFrameworkFactory.newClient(server.getConnectString(), sessionTimout,
connectionTimout, new RetryNTimes(0, 1))) {
client.start();
client.blockUntilConnected();
final InterProcessSemaphoreV2 semaphore = new
InterProcessSemaphoreV2(client, "/1", 1);
assertNotNull(semaphore.acquire());
CountDownLatch lost = new CountDownLatch(1);
client.getConnectionStateListenable().addListener((client1,
newState) -> {
if (newState == ConnectionState.LOST) {
lost.countDown();
}
});
server.stop();
lost.await();
}
server.restart();
try (CuratorFramework client =
CuratorFrameworkFactory.newClient(server.getConnectString(), sessionTimout,
connectionTimout, new RetryNTimes(0, 1))) {
client.start();
client.blockUntilConnected();
final InterProcessSemaphoreV2 semaphore = new
InterProcessSemaphoreV2(client, "/1", 1);
final int serverTick = ZooKeeperServer.DEFAULT_TICK_TIME
Thread.sleep(sessionTimout + serverTick);
assertNotNull(semaphore.acquire(0, TimeUnit.SECONDS));
}
}
{code}
And this is not passing: the doc of InterProcessSemaphoreV2 state that a LOST
lease is available to other clients to be acquired, maybe I'm missing something
obvious.
