"Unclosed ClusterNode object" with localhost

[dranikpg]

Version: 5.0.1
Platform: Python 3.10.12 on Ubuntu
Description:

Cluster nodes are leaked when "localhost" is used in the host with multiple range slots. This happens because they're cached by node.name

redis-py/redis/asyncio/cluster.py

Line 1300 in d529c2a

tmp_nodes_cache[target_node.name] = target_node

But queried by get_node_name

redis-py/redis/asyncio/cluster.py

Line 1294 in d529c2a

target_node = tmp_nodes_cache.get(get_node_name(host, port))

The difference between those two is that the former removes "localhost"

redis-py/redis/asyncio/cluster.py

Line 971 in d529c2a

if host == "localhost":

So we look for localhost and insert 127.0.0.1, evicting the previous entry
