Example 1 with ForkIdManager

use of org.hyperledger.besu.ethereum.eth.manager.ForkIdManager in project besu by hyperledger.

the class ForkIdsTest method testForkId.

@Test
public void testForkId() {
    final GenesisConfigFile genesisConfigFile = GenesisConfigFile.fromConfig(EthNetworkConfig.jsonConfig(chainName));
    final GenesisConfigOptions configOptions = genesisConfigFile.getConfigOptions();
    final ProtocolSchedule schedule = MainnetProtocolSchedule.fromConfig(configOptions, EvmConfiguration.DEFAULT);

    final ForkIdManager forkIdManager = new ForkIdManager(mockBlockchain, genesisConfigFile.getForks(), false);
    final var actualForkIds = Streams.concat(((MutableProtocolSchedule) schedule).streamMilestoneBlocks(), Stream.of(Long.MAX_VALUE)).map(block -> {
        blockNumber.set(block);
        return forkIdManager.getForkIdForChainHead();
    }).collect(Collectors.toList());
    assertThat(actualForkIds).containsExactlyElementsOf(expectedForkIds);
}

Example 2 with ForkIdManager
