how to wait until DHT bootstrap ready?

[mostcute]

the chat with rendezvous example use time.sleep(1 * time.Second) instead of block until bootstrap ready

how to wait until bootstrap ready in product env?

i see wait 1sec for bootstrap can not find peers stable, but 10 sec will be more stable,what is the correct way to block it ?

	kademliaDHT, err := dht.New(ctx, h, dht.BootstrapPeers(bootstrapPeers...))
	if err != nil {
		panic(err)
	}

	// Bootstrap the DHT. In the default configuration, this spawns a Background
	// thread that will refresh the peer table every five minutes.
	fmt.Println("Bootstrapping the DHT")
	if err = kademliaDHT.Bootstrap(ctx); err != nil {
		panic(err)
	}
	// Wait a bit to let bootstrapping finish (really bootstrap should block until it's ready, but that isn't the case yet.)
	time.Sleep(15 * time.Second)


	fmt.Println("Announcing ourselves...")
	routingDiscovery := drouting.NewRoutingDiscovery(kademliaDHT)
	dutil.Advertise(ctx, routingDiscovery, "find me here hahaha")
	fmt.Println("Successfully announced!")

	// Now, look for others who have announced
	// This is like your friend telling you the location to meet you.
	fmt.Println("Searching for other peers...")
	peerChan, err := routingDiscovery.FindPeers(ctx, "find me here hahaha")
	if err != nil {
		panic(err)
	}

if use time.sleep(1 * time.Second) ,peerChan might receive no peers sometimes (8/10 chance failed get peers),if increase to 10 *second , will get peer success everytime

If you have access to the instance of the DHT object, one way to do it is probably calling Bootstrap(), and then calling RefreshRoutingTable() waiting on the returned channel.

just like this right?

		if err = kademliaDHT.Bootstrap(ctx); err != nil {
			panic(err)
		}
		errchan := kademliaDHT.RefreshRoutingTable()
		<-errchan
