How to start and stop scheduled jobs?

[dthomas-sensonix]

I have a system where I would like to schedule one job to run at a fixed interval of time. I would also like to be able to start and stop that job. Currently I am starting the scheduler with scheduler.StartAsync().

I start the job with scheduler.Every(config.Config.Interval.Collection).Seconds().Do(collectData).

I stop the job with scheduler.Remove(collectData).

While this works, I can encounter scenarios where two instances of the job will run at the same time. This happens if I stop the job while it is running and restart it immediately. It appears that the scheduler views the subsequent call to Do(collectData) as a new job and does not honor any SingletonMode controls. This makes sense, but I would like a way to wait for the removed jobs to finish before I allow the user to start new jobs. I don't want to cancel any currently running jobs. Is there a way to do that?

I tried calling scheduler.Stop() to stop the job. While that worked, when I called scheduler.StartAsync() again the code generated a panic. Is there a way to clean up after a Stop() or reinitialize the scheduler such than it can be restarted? What is the preferred method here?

Hi @dthomas-sensonix i missed this discussion from you. The issue with stopping and restarting the scheduler has been fixed. Please pull the latest. Stop waits for all jobs to finish before returning.
