Summary: NativeLock is release if Lock is closed after obtain failed Key: LUCENE-5738 URL: https://issues.apache.org/jira/browse/LUCENE-5738 Project: Lucene - Core Issue Type: Bug Affects Versions: 4.8.1 Reporter: Simon Willnauer Fix For: 4.9, 5.0 if you obtain the NativeFSLock and try to obtain it again in the same JVM and close if if it fails another process will be able to obtain it. This is pretty trappy though. If you execute the main class twice the problem becomes pretty obvious. {noformat} import org.apache.lucene.store.Lock; import org.apache.lucene.store.NativeFSLockFactory; import java.io.File; import java.io.IOException; public class TestLock { public static void main(String[] foo) throws IOException, InterruptedException { NativeFSLockFactory lockFactory = new NativeFSLockFactory(new File("/tmp")); Lock lock = lockFactory.makeLock("LOCK"); if (lock.obtain()) { System.out.println("OBTAINED"); } else { lock.close(); System.out.println("FAILED"); } if (lock.obtain()) { System.out.println("OBTAINED AGAIN"); } else { lock.close(); System.out.println("FAILED on Second"); } Thread.sleep(Integer.MAX_VALUE); } } {noformat} -- This message was sent by Atlassian JIRA (v6.2#6252) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
