I have an embedded python application. which is a MFC app with
Python interpreter embedded.
In the App, I have a separate thread to execute a Python script
(using the PyRun_File), but if the user want to stop the executing
script, how should I do?
A possible way is terminate the thread of executing the scripts by
TerminateThread(). but TerminateThread() is unsafe and not
recommended.
guys, could you guide me on this?
You could use PyThreadState_SetAsyncExc (to "inject" an exception), or
perhaps PyErr_SetInterrupt (to emulate ^C, which in turn generates a
KeyboardInterrupt). This should work fine for well-behaved scripts, but if
it ignores all exceptions like this:
try: ...
except: pass
you'll have to look at ceval.c how to break out of the running loop.
(this is yet another argument against indiscriminately using a bare except
clause...)
