Example 1 with TargetChains

use of tech.pegasys.teku.beacon.sync.forward.multipeer.chains.TargetChains in project teku by ConsenSys.

the class MultipeerSyncService method create.

public static MultipeerSyncService create(final AsyncRunnerFactory asyncRunnerFactory, final AsyncRunner asyncRunner, final TimeProvider timeProvider, final RecentChainData recentChainData, final PendingPool<SignedBeaconBlock> pendingBlocks, final P2PNetwork<Eth2Peer> p2pNetwork, final BlockImporter blockImporter, final Spec spec) {

    final EventThread eventThread = new AsyncRunnerEventThread("sync", asyncRunnerFactory);
    final TargetChains finalizedTargetChains = new TargetChains();
    final TargetChains nonfinalizedTargetChains = new TargetChains();
    final BatchSync batchSync = BatchSync.create(eventThread, asyncRunner, recentChainData, new BatchImporter(blockImporter, asyncRunner), new BatchFactory(eventThread, new PeerScoringConflictResolutionStrategy()), Constants.SYNC_BATCH_SIZE, MultipeerCommonAncestorFinder.create(recentChainData, eventThread, spec), timeProvider);

    final PeerChainTracker peerChainTracker = new PeerChainTracker(recentChainData.getSpec(), eventThread, p2pNetwork, new SyncSourceFactory(asyncRunner, timeProvider), finalizedTargetChains, nonfinalizedTargetChains);
    peerChainTracker.subscribeToTargetChainUpdates(syncController::onTargetChainsUpdated);
    final SyncStallDetector syncStallDetector = new SyncStallDetector(spec, eventThread, asyncRunner, timeProvider, syncController, batchSync, recentChainData);

Example 2 with TargetChains

use of tech.pegasys.teku.beacon.sync.forward.multipeer.chains.TargetChains in project teku by ConsenSys.

the class BatchSyncTest method shouldFailSyncWhenTargetChainHasNoPeersAndThereAreNoOutstandingRequests.

@Test
void shouldFailSyncWhenTargetChainHasNoPeersAndThereAreNoOutstandingRequests() {
    final TargetChains targetChains = new TargetChains();
    targetChains.onPeerStatusUpdated(syncSource, targetChain.getChainHead());
    targetChain = targetChains.streamChains().findFirst().orElseThrow();
    // Start the sync
    final SafeFuture<SyncResult> result = sync.syncToChain(targetChain);
    // Then the last peer is moved off that chain but we keep waiting for pending requests
    targetChains.onPeerDisconnected(syncSource);
    assertThat(result).isNotDone();
    final int originalBatchCount = batches.size();
    // Next time the sync progresses, it aborts because there are no more peers.
    batches.receiveBlocks(batches.get(0));
    assertThat(result).isCompletedWithValue(SyncResult.FAILED);
    // No more batches created
    assertThat(batches).hasSize(originalBatchCount);
