Python: Lock directory

Question

AFAIK this code can be used to lock a directory:

class LockDirectory(object):
    def __init__(self, directory):
        assert os.path.exists(directory)
            


        

Answer 1

I found an answer here: Python: Lock directory

It is possible to lock a directory with this:

fcntl.flock(self.dir_fd, fcntl.LOCK_EX | fcntl.LOCK_NB)

Of course this is a lock which every code which plays in this game need to check first.

AFAIK this is called "advisory lock".
