the class SegmentedRaftLogPartialEntryRecoveryTest method incompleteEntriesAtTheEndShouldNotCauseFailures.

@Test
public void incompleteEntriesAtTheEndShouldNotCauseFailures() throws Throwable {
    // Given
    // we use a RaftLog to create a raft log file and then we will start chopping bits off from the end
    SegmentedRaftLog raftLog = createRaftLog(100_000);
    raftLog.start();
    // Add a bunch of entries, preferably one of each available kind.
    raftLog.append(new RaftLogEntry(4, new NewLeaderBarrier()));
    raftLog.append(new RaftLogEntry(4, new ReplicatedIdAllocationRequest(new MemberId(UUID.randomUUID()), IdType.RELATIONSHIP, 1, 1024)));
    raftLog.append(new RaftLogEntry(4, new ReplicatedIdAllocationRequest(new MemberId(UUID.randomUUID()), IdType.RELATIONSHIP, 1025, 1024)));
    raftLog.append(new RaftLogEntry(4, new ReplicatedLockTokenRequest(new MemberId(UUID.randomUUID()), 1)));
    raftLog.append(new RaftLogEntry(4, new NewLeaderBarrier()));

    // We use a temporary RecoveryProtocol to get the file to chop
    RecoveryProtocol recovery = createRecoveryProtocol();
    State recoveryState = recovery.run();
    String logFilename = recoveryState.segments.last().getFilename();
    File logFile = new File(logDirectory, logFilename);
    // When
    // We remove any number of bytes from the end (up to but not including the header) and try to recover
    // Then
    // No exceptions should be thrown
    truncateAndRecover(logFile, SegmentHeader.SIZE);
}
