示例1: bootstrapConnect
func bootstrapConnect(ctx context.Context, ph host.Host, peers []peer.PeerInfo) error {
if len(peers) < 1 {
return ErrNotEnoughBootstrapPeers
}
errs := make(chan error, len(peers))
var wg sync.WaitGroup
for _, p := range peers {
// performed asynchronously because when performed synchronously, if
// one `Connect` call hangs, subsequent calls are more likely to
// fail/abort due to an expiring context.
// Also, performed asynchronously for dial speed.
wg.Add(1)
go func(p peer.PeerInfo) {
defer wg.Done()
defer log.EventBegin(ctx, "bootstrapDial", ph.ID(), p.ID).Done()
log.Debugf("%s bootstrapping to %s", ph.ID(), p.ID)
ph.Peerstore().AddAddrs(p.ID, p.Addrs, peer.PermanentAddrTTL)
if err := ph.Connect(ctx, p); err != nil {
log.Event(ctx, "bootstrapDialFailed", p.ID)
log.Debugf("failed to bootstrap with %v: %s", p.ID, err)
errs <- err
return
}
log.Event(ctx, "bootstrapDialSuccess", p.ID)
log.Infof("bootstrapped with %v", p.ID)
}(p)
}
wg.Wait()
// our failure condition is when no connection attempt succeeded.
// So drain the errs channel, counting the results.
