python-redis-lock | Lock context manager implemented via redis SET NX EX

I think the context manager is not the major difference here, because if you see code of redis-py Lock they have the __enter__ and __exit__ added in there.

Both the Lock's seem to use SETNX for acquiring the lock:

• python-redis-lock: Github
• redis-py Lock: Github

The major difference I saw in there was the way blocking the threads work.

• In case of python-redis-lock they have been using BLPOP mechanism to block the thread, which to me seems like using redis's own version of blocking mechanism. Github code

Something like:

timed_out = not self._client.blpop(self._signal, blpop_timeout) and timeout

• In case of redis-py they seem use time module and its sleep method to block the thread to check whether the blocking has timedout.

Something like:
