        LockType

Class implementing dummy implementation of thread.LockType.

Compatibility is maintained by maintaining self.locked_status which is a boolean that stores the state of the lock. Pickling of the lock, though, should not be done since if the thread module is then used with an unpickled ``lock()`` from here problems could occur from this class not having atomic methods.

acquire(self, waitflag=None)

 

Dummy implementation of acquire().

For blocking calls, self.locked_status is automatically set to True and returned appropriately based on value of ``waitflag``. If it is non-blocking, then the value is actually checked and not set if it is already acquired. This is all done so that threading.Condition's assert statements aren't triggered and throw a little fit.
