we have GerritPatch and GerritPatchTuple classes, sometimes they're used in mix and the docstring doesn't document it correctly. The method below documents both classes, but most methods in clactions only specifies GerritPatch. Probably should refactor the two classes using some inheritance strategies.


  def MarkForgiven(self, change, reason=None):
    """Mark |change| as forgiven with |reason|.

    Args:
      change: A GerritPatch or GerritPatchTuple object.
