asyncio exception handler is supposed to catch *unhandled* exceptions only, not all raised ones. The first two cases from your example propagate raised exceptions to the caller, these exceptions are unwound in a regular manner. So, no need to call the exception handler. The third case is different, an exception from a spawned task is not propagated to the parent task implicitly. That's why the exception is *unhandled* and passed to the registered exception handler. ---------- resolution: -> not a bug stage: -> resolved status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39256> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
