It would be nice to add a type annotation here, so we can find issues before hitting "assert False" in production.


I think this should be "merge_recursivly", to be pep8 compliant.

Does this pass flake8?

Can you add a doc comment.

Can you add a small unit test for this.


I don't like assert False, especially with no extra logging. It will be hard to debug if we hit in production. How about raise a ValueError or TypeError or NotImplementedYet, and in the message. mention the types responsible for the error ?


This functionality needs a unit test.


Could this glob be any more specific?

Could you please clarify a little bit - how this test should looks like? Because glob.glob("%s*" % f) where f - is (e.g.) somefile.perf_data just returns all somefile.perf_data* files


Could this glob be any more specific?

I think no, because name of profile file can be quite different
