Not working with Redis version 4.5.2

[rajkumar21Virim]

With Redis version 4.5.2, I am getting IndexError: pop from empty list.
I had to downgrade Redis back to redis==4.4.1 to make it work again.

Error logs for the Redis version 4.5.2 attached below:

Same issue for 4.5.3
4.5.1 Seems to be fine

This is due to one of a series of bugs in redis-py: for 4.5.2 specifically I think it's redis/redis-py#2629, but also redis/redis-py#2581 redis/redis-py#1902 redis/redis-py#2583

The underlying issue is that they don't (or didn't) test Unix file sockets, which is how people connect to redislite. Then, when they started making changes to their network sockets code, they kept forgetting to apply corresponding changes to the file sockets to keep them compatible. I can't remember the resolution to that, but this is related: redis/redis-py#2588

As far as I know, this is not a bug in redislite. It's just that when connecting to redislite we're all exercising a code path in redis-py that is otherwise rarely used.

This issue isn't occurring with redis-py 5.0.0 so it appears the issue is fixed there and I'm going to close this issue since the problem isn't in redislite itself.
