Examples with InitializeEntry io.atomix.protocols.raft.storage.log.entry.InitializeEntry used on opensource projects

Example 1 with InitializeEntry

use of io.atomix.protocols.raft.storage.log.entry.InitializeEntry in project atomix by atomix.

the class AbstractLogTest method testResetTruncateZero.

@Test
public void testResetTruncateZero() throws Exception {
    RaftLog log = createLog();
    RaftLogWriter writer = log.writer();
    RaftLogReader reader = log.openReader(1, RaftLogReader.Mode.ALL);
    assertEquals(0, writer.getLastIndex());
    writer.reset(1);
    assertEquals(0, writer.getLastIndex());
    writer.append(new InitializeEntry(1, System.currentTimeMillis()));
    assertEquals(1, writer.getLastIndex());
    assertEquals(1, writer.getLastEntry().index());
    assertTrue(reader.hasNext());
    assertEquals(1, reader.next().index());
    writer.truncate(0);
    assertEquals(0, writer.getLastIndex());
    assertNull(writer.getLastEntry());
    writer.append(new InitializeEntry(1, System.currentTimeMillis()));
    assertEquals(1, writer.getLastIndex());
    assertEquals(1, writer.getLastEntry().index());
    assertTrue(reader.hasNext());
    assertEquals(1, reader.next().index());
}

    writer.commit(3);
    manager.apply(3).join();
    assertTrue(snapshotInstalled.get());
}
