Upgrading to 1.1.0 breaks the count method

[knightq]

The count method (changed in 1.1.0) is no longer returning (or sometimes may return) a nil, while previously an integer was always returned.

Hi @knightq can you give us some more details here? Ideally your version of redis used & a minimal example producing 0?

To me this seems weird, since from the lua script, that would mean that nothing is returned, but we should always return something there. Maybe the lua script silently errors and returns nil?
Can you also check if there is something in the logs of redis (maybe it logs script errors somewhere).

break the connection pool too

I setup Ratelimit with :

Ratelimit.new(rate_limit_key, {redis: Rails.cache.redis})

this implicit use the connection Pool
