    Session session = sessionBuilder().setTransactionId(transactionManager.beginTransaction(false)).build();
    QueryStateMachine stateMachine = QueryStateMachine.begin(new QueryId("query"), "ROLLBACK", session, URI.create("fake://uri"), true, transactionManager, accessControl, executor, metadata);
    assertTrue(stateMachine.getSession().getTransactionId().isPresent());
    assertEquals(transactionManager.getAllTransactionInfos().size(), 1);
    getFutureValue(new RollbackTask().execute(new Rollback(), transactionManager, metadata, new AllowAllAccessControl(), stateMachine, emptyList()));
    assertTrue(stateMachine.getQueryInfoWithoutDetails().isClearTransactionId());
    assertFalse(stateMachine.getQueryInfoWithoutDetails().getStartedTransactionId().isPresent());
    assertTrue(transactionManager.getAllTransactionInfos().isEmpty());
}

Example 2 with Rollback

use of com.facebook.presto.sql.tree.Rollback in project presto by prestodb.

the class TestRollbackTask method testNoTransactionRollback.

@Test
public void testNoTransactionRollback() throws Exception {
    TransactionManager transactionManager = createTestTransactionManager();
    AccessControl accessControl = new AccessControlManager(transactionManager);
    Session session = sessionBuilder().build();
    QueryStateMachine stateMachine = QueryStateMachine.begin(new QueryId("query"), "ROLLBACK", session, URI.create("fake://uri"), true, transactionManager, accessControl, executor, metadata);
    try {
        try {
            getFutureValue(new RollbackTask().execute(new Rollback(), transactionManager, metadata, new AllowAllAccessControl(), stateMachine, emptyList()));
            fail();
        } catch (CompletionException e) {
            throw Throwables.propagate(e.getCause());
        }
    } catch (PrestoException e) {
        assertEquals(e.getErrorCode(), NOT_IN_TRANSACTION.toErrorCode());
    }
    assertFalse(stateMachine.getQueryInfoWithoutDetails().isClearTransactionId());
    assertFalse(stateMachine.getQueryInfoWithoutDetails().getStartedTransactionId().isPresent());

@Test
public void testUnknownTransactionRollback() throws Exception {
    TransactionManager transactionManager = createTestTransactionManager();
    AccessControl accessControl = new AccessControlManager(transactionManager);
    Session session = sessionBuilder().setTransactionId(// Use a random transaction ID that is unknown to the system
    TransactionId.create()).build();
    QueryStateMachine stateMachine = QueryStateMachine.begin(new QueryId("query"), "ROLLBACK", session, URI.create("fake://uri"), true, transactionManager, accessControl, executor, metadata);
    getFutureValue(new RollbackTask().execute(new Rollback(), transactionManager, metadata, new AllowAllAccessControl(), stateMachine, emptyList()));
    // Still issue clear signal
    assertTrue(stateMachine.getQueryInfoWithoutDetails().isClearTransactionId());
    assertFalse(stateMachine.getQueryInfoWithoutDetails().getStartedTransactionId().isPresent());
    assertTrue(transactionManager.getAllTransactionInfos().isEmpty());
