redis.end possibly doesn't disconnect from redis server

[Dmitry-N-Medvedev]

Hi!

It seems that I do not understand how to properly shutdown redis client. Please, see below.

helper function:

module.exports.stop = async (redis) => {
    const endEventPromise = eventPromise('end', redis);

    const endOpPromise = new Promise((resolve, reject) => {
        try {
            redis.end();
            redis = null;
            resolve();
        } catch(err) {
            reject(err);
        }
    });

    return await Promise.all([endEventPromise, endOpPromise]);
}

before start:

127.0.0.1:6379> CLIENT LIST
id=2 addr=127.0.0.1:49254 fd=7 name= age=4798 idle=4798 flags=N db=0 sub=0 psub=0 multi=-1 qbuf=0 qbuf-free=0 obl=0 oll=0 omem=0 events=r cmd=NULL

after stop:

127.0.0.1:6379> CLIENT LIST
id=2 addr=127.0.0.1:49254 fd=7 name= age=4807 idle=4807 flags=N db=0 sub=0 psub=0 multi=-1 qbuf=0 qbuf-free=0 obl=0 oll=0 omem=0 events=r cmd=NULL

Note fd=10 is still active

after client kill:

127.0.0.1:6379> CLIENT LIST

127.0.0.1:6379> 

Note fd=10 has gone.

Can not reproduce, please try to set CLIENT SETNAME "driver" on start, or give me a full example, please.

Please try new version of driver, should work
