After rollback received messages not re-presented
-------------------------------------------------
Key: AMQ-2233
URL: https://issues.apache.org/activemq/browse/AMQ-2233
Project: ActiveMQ
Issue Type: Bug
Affects Versions: 5.2.0
Reporter: Dave Syer
After rollback received messages not re-presented. If I receive in a
transaction and then roll back the messages should be re-presented in the next
transaction. This used to work in 5.1.0, but is broken in 5.2.0.
You can browse the Queue in JMX after the rollback and see that the messages
are still there, but they are not received by a consumer in the same process.
Here's a test case (fails on the checkPostConditions()):
{code}
public class RawRollbackTests {
private static ConnectionFactory connectionFactory;
private static Destination queue;
private static BrokerService broker;
@BeforeClass
public static void clean() throws Exception {
FileUtils.deleteDirectory(new File("activemq-data"));
broker = new BrokerService();
broker.setUseJmx(true);
broker.start();
ActiveMQConnectionFactory connectionFactory = new
ActiveMQConnectionFactory();
connectionFactory.setBrokerURL("vm://localhost?async=false");
RawRollbackTests.connectionFactory = connectionFactory;
queue = new ActiveMQQueue("queue");
}
@AfterClass
public static void close() throws Exception {
broker.stop();
}
@Before
public void clearData() throws Exception {
getMessages(false); // drain queue
convertAndSend("foo");
convertAndSend("bar");
}
@After
public void checkPostConditions() throws Exception {
Thread.sleep(1000L);
List<String> list = getMessages(false);
assertEquals(2, list.size());
}
@Test
public void testReceiveMessages() throws Exception {
List<String> list = getMessages(true);
assertEquals(2, list.size());
assertTrue(list.contains("foo"));
}
private void convertAndSend(String msg) throws Exception {
Connection connection = connectionFactory.createConnection();
connection.start();
Session session = connection.createSession(true,
Session.AUTO_ACKNOWLEDGE);
MessageProducer producer = session.createProducer(queue);
producer.send(session.createTextMessage(msg));
producer.close();
session.commit();
session.close();
connection.close();
}
private List<String> getMessages(boolean rollback) throws Exception {
Connection connection = connectionFactory.createConnection();
connection.start();
Session session = connection.createSession(true,
Session.AUTO_ACKNOWLEDGE);
String next = "";
List<String> msgs = new ArrayList<String>();
while (next != null) {
next = (String) receiveAndConvert(session);
if (next != null)
msgs.add(next);
}
if (rollback) {
session.rollback();
} else {
session.commit();
}
session.close();
connection.close();
return msgs;
}
private String receiveAndConvert(Session session) throws Exception {
MessageConsumer consumer = session.createConsumer(queue);
Message message = consumer.receive(100L);
consumer.close();
if (message==null) {
return null;
}
return ((TextMessage)message).getText();
}
}
{code}
