A platform independent file lock.

Project description

This package contains a single module, which implements a platform independent file lock in Python.

The lock includes a lock counter and is thread safe. This means, when locking the same lock object twice, it will not block.

import filelock

lock = filelock.FileLock("my_lock_file")

with lock:
        pass

try:
        with lock.acquire(timeout = 10):
                pass
except filelock.Timeout:
        pass

What this filelock is not

A filelock provides a synchronisation mechanism between different instances of your application, similar to a thread lock. It can be used to signalize that files, directories or other resources are currently used or manipulated (Think of a sync.lock file). Only the existence of the lockfile is watched for this purpose. The file itself can not be written and is always empty.
