Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 6, in coroutine
TypeError: exceptions must be classes or instances, not NoneType
Seems that yielding in the except clause makes python forget the current
exception, so a bar "raise" statement raises None, instead of the
original exception.
changing except to except Exception,e: and raise to raise e throws the
original exception, but then the original stack trace is lost. |
