* bpo-44630: Fix assertion errors in csv module (GH-27127)T. Wouters2021-07-131-0/+6
| | | | | | | | | | | | | Fix incorrect handling of exceptions when interpreting dialect objects in the csv module. Not clearing exceptions between calls to PyObject_GetAttrString() causes assertion failures in pydebug mode (or with assertions enabled). Add a minimal test that would've caught this (passing None as dialect, or any object that isn't a csv.Dialect subclass, which the csv module allows and caters to, even though it is not documented.) In pydebug mode, the test triggers the assertion failure in the old code. Contributed-By: T. Wouters [Google]
