Example 1 with IncompleteLogHeaderException

use of org.neo4j.kernel.impl.transaction.log.entry.IncompleteLogHeaderException in project neo4j by neo4j.

the class PhysicalLogFileTest method shouldCloseChannelInFailedAttemptToReadHeaderAfterOpen.

@Test
public void shouldCloseChannelInFailedAttemptToReadHeaderAfterOpen() throws Exception {
    // GIVEN a file which returns 1/2 log header size worth of bytes
    File directory = new File("/dir");
    FileSystemAbstraction fs = mock(FileSystemAbstraction.class);
    PhysicalLogFiles logFiles = new PhysicalLogFiles(directory, fs);
    int logVersion = 0;
    File logFile = logFiles.getLogFileForVersion(logVersion);
    StoreChannel channel = mock(StoreChannel.class);
    when(channel.read(any(ByteBuffer.class))).thenReturn(LogHeader.LOG_HEADER_SIZE / 2);
    when(fs.fileExists(logFile)).thenReturn(true);
    when(fs.open(eq(logFile), anyString())).thenReturn(channel);
    // WHEN
    try {

        fail("Should have failed");
    } catch (IncompleteLogHeaderException e) {
