py3: fix module imports in tests, as flagged by test-check-module-imports.t I have no idea why these aren't flagged with python2. I excluded test-highlight.t for now to make this easier to review- the changed code is committed to a repo, which has cascading changes on the rest of the test. There's a mix of bytes and str in the imports dict of contrib/import-checker.py that crashed it half way through listing out these errors. I couldn't figure out how to fix that properly, so I was lazy and applied this on py3, to find the rest of the errors: diff --git a/contrib/import-checker.py b/contrib/import-checker.py --- a/contrib/import-checker.py +++ b/contrib/import-checker.py @@ -626,7 +626,12 @@ def find_cycles(imports): top.foo -> top.qux -> top.foo """ cycles = set() - for mod in sorted(imports.keys()): + def sort(v): + if isinstance(v, bytes): + return v.decode('ascii') + return v + + for mod in sorted(imports.keys(), key=sort): try: checkmod(mod, imports) except CircularImport as e:
