Bug in client-side caching support when handling hash READ operations that specify field(s) #3612
Description
there seems to be a bug in client-side caching support when handling hash READ operations that specify field(s), such as HGET and HMGET.
current implementation only stores redis_keys and not hash field names, so the cache entry is shared for different field combinations and end up returning the wrong value.
it's easy to reproduce:
import redis from redis.cache import CacheConfig url = 'xxx' key = 'abcde' r = redis.from_url(url, protocol=3, cache_config=CacheConfig()) r1 = redis.from_url(url) r1.hset(key, mapping={'field1': 'aaa', 'field2': 'bbb'}) print(r.hget(key, 'field1')) # prints 'aaa' print(r.hget(key, 'field2')) # should print 'bbb', but uses the cache entry created in previous line and prints 'aaa'
