"restart" node in bonsai

[edmundchong]

Is there some functionality in bonsai code to restart the entire workflow after it has been run? i.e. equivalent to clicking on the "Restart" button. So basically if some event is triggered within the workflow while it is running, it can restart the entire thing.

Thanks again!

Hmm there is no way to do it within the Bonsai editor I believe. Could you describe why/what you want to achieve, there might be a way to achieve what you want without having to restart the entire workflow.

Usually when something goes wrong in my workflows (e.g. some piece of hardware somewhere momentarily fails), and some key information streams will then be interrupted as a consequence. I have a quick workflow (using BufferTime) that detects when an information stream has not produced anything in the past x minutes, and then a hard reset would generically solve issues. I guess I could also track each piece of hardware separately and reset it individually :)

In addition to what @glopesdev said, there's also an operator called Retry that might work for you (if your workflow can handle the missing data appropriately and if an error is raised). Do those hardware failures throw an exception? It seems weird to me that they might not produce anything but not raise an error. If there is no exception being thrown, the TimeOut operator can raise one.

no exception is thrown, it just freezes--but I did not know about TimeOut; will use it in place of my improvised method. this is very helpful, thanks again!

@edmundchong maybe one way to think about it is to wrap your entire workflow inside a GroupWorkflow, with the event you want going into a WorkflowOutput node after a Take(1).

Then you can simply add a Repeat node after the group at the top-level workflow.

this will work thanks!
