Use redis over SSH channel error

[slowrookie]

• Use Redis over SSH channels

sshConfig := &ssh.ClientConfig{
		User:            "root",
		Auth:            []ssh.AuthMethod{ssh.Password("password")},
		HostKeyCallback: ssh.InsecureIgnoreHostKey(),
		Timeout:         15 * time.Second,
}

client, err := ssh.Dial("tcp", "remoteIp:22", sshConfig)
if err != nil {
log.Println(fmt.Errorf("%v", err))
}

cli := redis.NewClient(&redis.Options{
		Addr: net.JoinHostPort("127.0.0.1", "6379"),
  Dialer: func(ctx context.Context, network, addr string) (net.Conn, error) {
	  log.Println(fmt.Sprintf("%s %s", network, addr))
	  return client.Dial(network, addr)
  },
  })

_, err = cli.Ping(context.Background()).Result()
if nil != err {
log.Println(fmt.Errorf("%v", err))
}

• Error:
  ssh: tcpChan: deadline not supported

• Reason:
  in the redis/interal/pool/conn.og use cn.netConn.SetReadDeadline and cn.netConn.SetWriteDeadline

I guess we could ignore errors returned from SetReadDeadline. Send a PR if you are interested.

when set ReadTimeout & WriteTimeout to -1 and disable SetReadDeadline

        cli := redis.NewClient(&redis.Options{
		ReadTimeout:  -1,
		WriteTimeout: -1,
	})

        cli := redis.NewClient(&redis.Options{
		ReadTimeout:  -1,
		WriteTimeout: -1,
	})

请问咋禁用 SetReadDeadline 呀？单独设置 ReadTimeout、WriteTimeout 没效果呢

[slowrookie]

@GetcharZp 如果使用最新版本。#2176 已修复该问题。解决办法： #2176 (comment)

cli := redis.NewClient(&redis.Options{
    ReadTimeout:  -2,
    WriteTimeout: -2,
})

如果配置项如上图所示，则client.BLPop(ctx, 0, q.conf.queueName).Result() 报如标题错误，大家有兼容方案吗
