This commit turns
redisEnableKeepAlive
into a no-op forREDIS_CONN_UNIX
connections.I'm not sure there's much benefit by actually breaking the connection (e.g. setting
c-.err
andc->errstr
) for the operation, so instead we just returnREDIS_ERR
fromredisEnableKeepAlive
but leave the connection in a good state.Fixes #1185
