redlock-py - Redis distributed locks in Python
This python lib implements the Redis-based distributed lock manager algorithm
[described in this blog post](http://antirez.com/news/77).
To create a lock manager:
dlm = Redlock([{"host": "localhost", "port": 6379, "db": 0}, ])
To acquire a lock:
my_lock = dlm.lock("my_resource_name",1000)
Where the resource name is an unique identifier of what you are trying to lock
and 1000 is the number of milliseconds for the validity time.
The returned value is `False` if the lock was not acquired (you may try again),
otherwise an namedtuple representing the lock is returned, having three fields:
* validity, an integer representing the number of milliseconds the lock will be valid.
* resource, the name of the locked resource as specified by the user.
* key, a random value which is used to safe reclaim the lock.
To release a lock:
dlm.unlock(my_lock)
It is possible to setup the number of retries (by default 3) and the retry
delay (by default 200 milliseconds) used to acquire the lock.
**Disclaimer**: This code implements an algorithm which is currently a proposal,
it was not formally analyzed. Make sure to understand how it works before using it
in your production environments.
