use of org.neo4j.kernel.ha.transaction.CommitPusher in project neo4j by neo4j.

the class TestMasterCommittingAtSlave method newPropagator.

private TransactionPropagator newPropagator(int slaveCount, int replication, SlavePriority slavePriority, boolean... failingSlaves) throws Exception {
    slaves = instantiateSlaves(slaveCount, failingSlaves);
    Config config = Config.embeddedDefaults(MapUtil.stringMap(HaSettings.tx_push_factor.name(), "" + replication, ClusterSettings.server_id.name(), "" + MasterServerId));

    TransactionPropagator result = new TransactionPropagator(TransactionPropagator.from(config, slavePriority), NullLog.getInstance(), new Slaves() {

        @Override
        public Iterable<Slave> getSlaves() {
            return slaves;
        }
    }, new CommitPusher(scheduler));
    // Life
    try {
        scheduler.init();
        scheduler.start();
        result.init();
        result.start();
    } catch (Throwable e) {
