示例1: Do

// execute some action in the deferred context of the process, but only if we
// match the stage of the process at the time the action is executed.
func (stage stageType) Do(p *SchedulerProcess, a proc.Action) <-chan error {
	errOnce := proc.NewErrorOnce(p.fin)
	errOuter := p.Do(proc.Action(func() {
		switch stage {
		case standbyStage:
			//await standby signal or death
			select {
			case <-p.standby:
			case <-p.Done():
			}
		case masterStage:
			//await elected signal or death
			select {
			case <-p.elected:
			case <-p.Done():
			}
		case finStage:
			errOnce.Reportf("scheduler process is dying, dropping action")
			return
		default:
		}
		errOnce.Report(stage.When(p, a))
	}))
	return errOnce.Send(errOuter).Err()
}

示例2: Elect

func (self *SchedulerProcess) Elect(newDriver DriverFactory) {
	errOnce := proc.NewErrorOnce(self.fin)
	proc.OnError(errOnce.Send(standbyStage.Do(self, proc.Action(func() {
		if !(&self.stage).transition(standbyStage, masterStage) {
			log.Errorf("failed to transition from standby to master stage, aborting")
			self.End()
			return
		}
		log.Infoln("scheduler process entered master stage")
		drv, err := newDriver()
		if err != nil {
			log.Errorf("failed to fetch scheduler driver: %v", err)
			self.End()
			return
		}
		log.V(1).Infoln("starting driver...")
		stat, err := drv.Start()
		if stat == mesos.Status_DRIVER_RUNNING && err == nil {
			log.Infoln("driver started successfully and is running")
			close(self.elected)
			go func() {
				defer self.End()
				_, err := drv.Join()
				if err != nil {
					log.Errorf("driver failed with error: %v", err)
				}
				errOnce.Report(err)
			}()
			return
		}
		defer self.End()
		if err != nil {
			log.Errorf("failed to start scheduler driver: %v", err)
		} else {
			log.Errorf("expected RUNNING status, not %v", stat)
		}
	}))).Err(), func(err error) {
		defer self.End()
		log.Errorf("failed to handle election event, aborting: %v", err)
	}, self.fin)
