Chris Angelico added the comment: PyErr_Restore doesn't seem to trigger exception chaining. But thanks for the tip about explicitly setting the traceback; not sure how I missed that, but now the StopIteration traceback is visible.
Minor point: The previous patch was setting the __context__ of the RuntimeError, whereas it ought to have been setting __cause__. Have corrected that. So here, before I move further forward, is a new POC patch; I've removed the patches that rhettinger applied already, and fixed up tracebacks. So now it's a better-behaved POC, at least. ---------- Added file: http://bugs.python.org/file37640/pep0479.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22906> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
