R. David Murray added the comment: This is presumably a result of the exception object being saved on the context manager object and there being a circular reference chain that doesn't immediately get GCed. This is just how python works.
I don't know if it would be sensible/useful to use the new lightweight traceback stuff in assertRaises. If so it would probably have to be optional for backward compatibility reasons. ---------- nosy: +r.david.murray type: behavior -> enhancement versions: +Python 3.5 -Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue23890> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
