In my patch the exception state does not need swapping at all, so the question of whose responsibility it is become mute.

This patch is largely orthogonal to that proposed for issue 13607. In fact the new CoState struct would be a better place to pass data between PyEval_EvalFrame() and gen_send(), rather than adding yet another field to the frame. ---------- title: Move fields relevant to coroutine/generators out of frame into generator/threadstate -> Move fields relevant to coroutine/generators out of frame into generator/threadstate _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue13897> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
