I’m having some trouble understanding the Importer Protocol as per http://www.python.org/dev/peps/pep-0302/. Should the fullname argument of finder.find_module(fullname, path=None) never include a . (dot)?

That is, if you want to find module abc.efg.hij, you must call finder.find_module('hij', path='abc.efg'). Calling finder.find_module('abc.efg.hij') would be absolutely incorrect.

Is this correct?

    No, it is just saying that import abc.efg.hij will eventually result in 3 different find_module calls at various stages of the import process:

    find_module("abc", None)
find_module("abc.efg", abc.__path__)
find_module("abc.efg.hij", abc.efg.__path__)

    Exploring the importlib documentation may also be of interest to you:
