Hi All,
I see in Python 3, some ImportErrors have grown a '_not_found' attribute. What's the significance of this attribute and where/how is it added?
The only way I can seem to create this attribute is:
ex = ImportError ex._not_found = True
It's something importlib does to get fromlists to behave the same way they did in the C implementation. It is set here: http://hg.python.org/cpython/file/3.3/Lib/importlib/_bootstrap.py To make these pass: http://hg.python.org/cpython/file/3.3/Lib/test/test_importlib/import_/test_f... You'd have to ask Brett which specific test is affected, or else you could comment out the line that sets _not_found and see what breaks (you may need to refreeze _frozen_importlib first).
