I'd love if there was a version of doit.tools.LongRunning that had it return TaskError if return code was non zero. I tend to use this for a light build system for tasks that have dependencies, and having it not stop at the first error requires a bunch of scrolling and buries problems.

I tend to unroll it in my own dodo.py scripts, but it'd be nice if it was inbuilt. I ended up hacking my own locally in my dodo.py and it works quite nicely:

class LongRunningTask(doit.tools.CmdAction):
	' Run a command and wait for it to finish, and fail if it fails.'

	def execute(self, out=None, err=None):
		action = self.expand_action()
		process = subprocess.Popen(
			action, shell=self.shell, stdout=out, stderr=err, **self.pkwargs,)
		try:
			return_value = process.wait()
		
			if return_value != 0:
				return doit.exceptions.TaskError(f'Command failed with return code {return_value}')

		except KeyboardInterrupt:
			# normal way to stop interactive process
			pass
