[Buildbot-devel] Running a buildstep only if previous steps completed successfully.

Hi Scott,

I've had a rather similar need, I had to check the state of the previous 
build step. I used a custom buid step class, with the following function:

    def getPreviousStepStatus(self):
        steps_status = self.build.build_status.getSteps()
        self_status_index = steps_status.index(self.step_status)
        if self_status_index == 0:
            return (None, 0)
        return steps_status[self_status_index - 1].results

By iterating on self.build.build_status.getSteps() and checking the 'result' 
attribute, you should be able to do you want. The tuple (None, 0) means 
there is no result available yet, it could be your break condition.

Cheers,
Aurélien
