NewClusterClient.Get context does not take effect

[fengcunwu]

When I use go-redis v8 NewClusterClient, create a client and use Get to get the key data, and set the context timeout, the context takes effect, but the Get command takes longer than the context timeout

func TestGoRedis(t *testing.T) {
	ctx, cancel := context.WithTimeout(context.TODO(), 200*time.Millisecond)
	defer cancel()
	client := goredisv8.NewClusterClient(&goredisv8.ClusterOptions{
		Addrs:      strings.Split("127.0.0.1:30001", ";"),
		MaxRetries: 0,
	})

	now := time.Now()
	fmt.Println(client.Get(ctx, "test").Result())
	fmt.Println(time.Now().Sub(now).Milliseconds())
}

demo As above, the result I get is:

=== RUN TestGoRedis
context deadline exceeded
603ms
--- PASS: TestGoRedis (0.60s)
PASS

gomod: github.com/go-redis/redis/v8 v8.11.5

127.0.0.1:30001 is available. In the Get function, I pause the program for 500ms when getting the link to simulate the delay time of the redis cluster. The code is as follows

func (p *ConnPool) popIdle() (*Conn, error) {
	if p.closed() {
		return nil, ErrClosed
	}
	n := len(p.idleConns)
	if n == 0 {
		return nil, nil
	}

	var cn *Conn
	if p.opt.PoolFIFO {
		cn = p.idleConns[0]
		copy(p.idleConns, p.idleConns[1:])
		p.idleConns = p.idleConns[:n-1]
	} else {
		idx := n - 1
		cn = p.idleConns[idx]
		p.idleConns = p.idleConns[:idx]
		time.Sleep(500*time.Millisecond)
	}
	p.idleConnsLen--
	p.checkMinIdleConns()
	return cn, nil
}
