Examples with TransactionException org.apache.ignite.tx.TransactionException used on opensource projects

Example 1 with TransactionException

use of org.apache.ignite.tx.TransactionException in project ignite-3 by apache.

the class TxAbstractTest method testIncrement2.

/**
 * Tests if a lost update is not happening on concurrent increment.
 */
@Test
public void testIncrement2() throws TransactionException, InterruptedException {
    InternalTransaction tx = (InternalTransaction) igniteTransactions.begin();
    InternalTransaction tx2 = (InternalTransaction) igniteTransactions.begin();
    Tuple key = makeKey(1);
    Tuple val = makeValue(1, 100.);
    // Creates implicit transaction.
    accounts.recordView().upsert(null, val);
    var table = accounts.recordView();
    var table2 = accounts.recordView();
    // Read in tx
    double valTx = table.get(tx, key).doubleValue("balance");
    // Read in tx2
    double valTx2 = table2.get(tx2, key).doubleValue("balance");
    // Write in tx2 (should wait for read unlock in tx1)
    CompletableFuture<Void> fut = table2.upsertAsync(tx2, makeValue(1, valTx2 + 1));
    // Give some time to update lock queue TODO asch IGNITE-15928
    Thread.sleep(300);
    assertFalse(fut.isDone());
    CompletableFuture<Void> fut2 = fut.thenCompose(ret -> tx2.commitAsync());
    // Write in tx
    table.upsert(tx, makeValue(1, valTx + 1));
    tx.commit();
    Exception err = assertThrows(Exception.class, () -> fut2.get(5, TimeUnit.SECONDS));
    assertTrue(err.getMessage().contains("Failed to acquire a lock"), err.getMessage());
    assertEquals(101., accounts.recordView().get(null, key).doubleValue("balance"));
}

Example 2 with TransactionException

use of org.apache.ignite.tx.TransactionException in project ignite-3 by apache.

the class TxAbstractTest method testPutAll.

@Test
public void testPutAll() throws TransactionException {
    igniteTransactions.runInTransaction(tx -> {
        accounts.recordView().upsertAll(tx, List.of(makeValue(1, 100.), makeValue(2, 200.)));
    });
    validateBalance(accounts.recordView().getAll(null, List.of(makeKey(2), makeKey(1))), 200., 100.);
    assertThrows(IgniteException.class, () -> igniteTransactions.runInTransaction(tx -> {
        accounts.recordView().upsertAll(tx, List.of(makeValue(3, 300.), makeValue(4, 400.)));
        if (true) {
            throw new IgniteException();
        }
    }));
    assertNull(accounts.recordView().get(null, makeKey(3)));
    assertNull(accounts.recordView().get(null, makeKey(4)));
}

Example 3 with TransactionException

use of org.apache.ignite.tx.TransactionException in project ignite-3 by apache.

the class TxManagerImpl method finishRemote.

/**
 * {@inheritDoc}
 */
@Override
public CompletableFuture<Void> finishRemote(NetworkAddress addr, Timestamp ts, boolean commit, Set<String> groups) {
    assert groups != null && !groups.isEmpty();
    TxFinishRequest req = FACTORY.txFinishRequest().timestamp(ts).groups(groups).commit(commit).build();
    CompletableFuture<NetworkMessage> fut = clusterService.messagingService().invoke(addr, req, TIMEOUT);
    // Submit response to a dedicated pool to avoid deadlocks. TODO: IGNITE-15389
    return fut.thenApplyAsync(resp -> ((TxFinishResponse) resp).errorMessage()).thenCompose(msg -> msg == null ? completedFuture(null) : failedFuture(new TransactionException(msg)));
}

Example 4 with TransactionException

use of org.apache.ignite.tx.TransactionException in project ignite-3 by apache.

the class TxManagerImpl method readLock.

/**
 * {@inheritDoc}

@Override
public CompletableFuture<Void> readLock(IgniteUuid lockId, ByteBuffer keyData, Timestamp ts) {
    TxState state = state(ts);
    if (state != null && state != TxState.PENDING) {
        return failedFuture(new TransactionException("The operation is attempted for completed transaction"));
    }
    LockKey key = new LockKey(lockId, keyData);
    return lockManager.tryAcquireShared(key, ts).thenAccept(ignored -> recordLock(key, ts, Boolean.TRUE));
}

Example 5 with TransactionException

use of org.apache.ignite.tx.TransactionException in project ignite-3 by apache.

the class TxManagerImpl method writeLock.

/**
 * {@inheritDoc}
 */
@Override
public CompletableFuture<Void> writeLock(IgniteUuid lockId, ByteBuffer keyData, Timestamp ts) {
    // TODO IGNITE-15933 process tx messages in striped fasion to avoid races. But locks can be acquired from any thread !
    TxState state = state(ts);
    if (state != null && state != TxState.PENDING) {
        return failedFuture(new TransactionException("The operation is attempted for completed transaction"));
    }
    // Should rollback tx on lock error.
    LockKey key = new LockKey(lockId, keyData);
    return lockManager.tryAcquire(key, ts).thenAccept(ignored -> recordLock(key, ts, Boolean.FALSE));
