Subject [jira] Created: (JCR-2809) Lock expires almost immediately
Date Wed, 10 Nov 2010 17:47:14 GMT
Lock expires almost immediately

                 Key: JCR-2809
                 URL: https://issues.apache.org/jira/browse/JCR-2809
             Project: Jackrabbit Content Repository
          Issue Type: Bug
          Components: locks
    Affects Versions: 2.1.2
            Reporter: Dominique Pfister

When a timeoutHint other than Long.MAX_VALUE is given to the javax.jcr.lock.LockManager API:

   lock(String absPath, boolean isDeep, boolean isSessionScoped, long timeoutHint, String

a timeoutTime in seconds will be computed as follows (o.a.j.core.lock.LockInfo#updateTimeoutTime):

   long now = (System.currentTimeMillis() + 999) / 1000; // round up
   this.timeoutTime = now + timeoutHint;

the TimeoutHandler in o.a.j.core.lock.LockManagerImpl running every second will then check
whether the timeout has expired (o.a.j.core.lock.LockInfo#isExpired):

    public boolean isExpired() {
        return timeoutTime != Long.MAX_VALUE
            && timeoutTime * 1000 > System.currentTimeMillis();

Obviously, the latter condition is true from the very beginning. Replacing '>' with '<'
or '<=' should do the trick.
