示例1: waitForAgentInitialisation

// waitForAgentInitialisation polls the bootstrapped state server with a read-only
// command which will fail until the state server is fully initialised.
// TODO(wallyworld) - add a bespoke command to maybe the admin facade for this purpose.
func (c *BootstrapCommand) waitForAgentInitialisation(ctx *cmd.Context) (err error) {
	attempts := utils.AttemptStrategy{
		Min:   bootstrapReadyPollCount,
		Delay: bootstrapReadyPollDelay,
	}
	var client block.BlockListAPI
	for attempt := attempts.Start(); attempt.Next(); {
		client, err = blockAPI(&c.EnvCommandBase)
		if err != nil {
			return err
		}
		_, err = client.List()
		client.Close()
		if err == nil {
			ctx.Infof("Bootstrap complete")
			return nil
		}
		if strings.Contains(err.Error(), apiserver.UpgradeInProgressError.Error()) {
			ctx.Infof("Waiting for API to become available")
			continue
		}
		return err

示例2: waitForAgentInitialisation

// waitForAgentInitialisation polls the bootstrapped controller with a read-only
// command which will fail until the controller is fully initialised.
// TODO(wallyworld) - add a bespoke command to maybe the admin facade for this purpose.
func (c *bootstrapCommand) waitForAgentInitialisation(ctx *cmd.Context) (err error) {
	attempts := utils.AttemptStrategy{
		Min:   bootstrapReadyPollCount,
		Delay: bootstrapReadyPollDelay,
	}
	var client block.BlockListAPI
	for attempt := attempts.Start(); attempt.Next(); {
		client, err = blockAPI(&c.ModelCommandBase)
		if err != nil {
			// Logins are prevented whilst space discovery is ongoing.
			errorMessage := err.Error()
			if strings.Contains(errorMessage, "space discovery still in progress") {
				continue
			}
			return err
		}
		_, err = client.List()
		client.Close()
		if err == nil {
			ctx.Infof("Bootstrap complete")
			return nil
		}
		// As the API server is coming up, it goes through a number of steps.
		// Initially the upgrade steps run, but the api server allows some
		// calls to be processed during the upgrade, but not the list blocks.
		// It is also possible that the underlying database causes connections
		// to be dropped as it is initialising, or reconfiguring. These can
		// lead to EOF or "connection is shut down" error messages. We skip
		// these too, hoping that things come back up before the end of the
		// retry poll count.
		errorMessage := err.Error()
		if strings.Contains(errorMessage, apiserver.UpgradeInProgressError.Error()) ||
			strings.HasSuffix(errorMessage, "EOF") ||
			strings.HasSuffix(errorMessage, "connection is shut down") {
			ctx.Infof("Waiting for API to become available")
			continue
