[Buildbot-devel] Dynamic steps in buildbot

I did this a different way.

I have a special step (e.g. DynamicSteps).  It runs a script inside the repository that returns the set of new steps.
Then I set a custom Build class on the builder (e.g. DynamicRemoteBuild inheriting from Build).
Then in stepDone, I check if the completed step is an instance of DynamicSteps.

If it is, then I take the new set of steps & inject into self.steps & self.build_status.steps, taking care to maintain the correct order
so that it looks like the steps are inserted into the middle of the build.

DynamicSteps simply parses the log output to determine the set of new steps.
