[Buildbot-devel] [Need help] with "got_revision" for multi-codebase builds in build steps

[Jared Grubb]

Interpolate works well for simple substitution. 

However, for this purpose, you probably would do better doing a custom render function:

   from buildbot.process import properties

   @properties.renderer
   def create_filename(props):
       got_revision = props.getProperty(‘got_revision’)
       rev = got_revision.get(‘Repo3’, ‘(unknown)’)

      # If you need the sourcestamp, you can do something like:
      # ss = props.getBuild().getSourceStamp(‘Repo3’)

       return rev
