Hi, according to the EVAL docs, if "a Redis command call will result into an error, redis.call() will raise a Lua error". But check this out:
redis> eval "redis.call('llen', nil)" 0
(nil)
Command returned ok. But the redis.call did return a lua error:
redis> eval "local res = redis.call('llen', nil) return res" 0
(error) Lua redis() command arguments must be strings or integers
I suppose I was expecting something similar to this to happen:
redis> eval "redis.call('llen')" 0
(error) ERR Error running script (call to f_6fb575faf03c0feac7654c95d6dd9d9de1e75144): Wrong number of args calling Redis command From Lua script
This seems to happen with any command:
redis> eval "redis.call('hset', 'foo', 'bar', nil)" 0
(nil)
