[Python-Dev] is this the fault of import_fresh_module or pickle? (original) (raw)

pickle always looks up sys.modules['xml.etree.ElementTree']. Perhaps we could improve something, but this requirement is rather special; personally I'm okay with switching sys.modules explicitly in the tests, because that reminds me of what pickle does.

Wouldn?t it be be better if importfreshmodule or some alternative function could do that for you? I mean, wipe out the import cache for certain modules I don't want to be found?

For a single test, perhaps. ContextAPItests.test_pickle() from test_decimal would look quite strange if import_fresh_module was used repeatedly.
