Robert Collins added the comment: We can't use from_exception in __init__ because from_exception's job is to look up __traceback__, but the legacy API allows arbitrary tb objects which may not be exc.__traceback__, and modifying exc.__traceback__ or creating a shim object just to be able to use from_exception doesn't make sense to me.
This patch looks good, and I'm applying to 3.6. It has no functional impact (except for perhaps weird mocking corner cases, but as its a pure class that shouldn't be needed), so I'm leaving it out of 3.5, since i'm not 100% sure where the move to a new repo is at, and its not worth figuring that out. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue24710> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
