[issue15111] Wrong ImportError message with importlib

[Brett Cannon]

Brett Cannon added the comment:

Here are two possible tests.

1) __import__('distutils', fromlist=['_i_do_not_exist']) should return distutils

2) Use a fake loader which executes some code which does nothing more than tries to import a non-existent module. The trick with this test is that the submodule must be found but a module that the submodule needs cannot be found by import itself (and simply not faked with an ImportError thanks to the _not_found hack and needing that attribute to propagate up to the submodule search).

And I think the failure stems from the lack of check against exc.name equaling the name of the module being imported (e.g. exc.name == distutils.msvc9compiler) since the winreg import is a failed module search as well.
