Starting Debugger On Errors In Threads

I'm using following trick to get debugger started on error Starting python debugger automatically on error Any idea how to make this also work for errors that happen in newly creat

Solution 1:

I'd say inject that code in the beginning of each Thread's run().

If you don't want to change that code, you could do monkeypatch it e.g. like this:

Worker.run = lambda *a: [init_pdb(), Worker.run(*a)][-1]

Or like this:

defwrapper(*a):
    # init pdb here
    Worker.run(*a)

Worker.run = wrapper

If you wanna go real hardcore, you can override threading.Thread.start, or possibly threading.Thread altogether before you import other modules, e.g.:

classDebuggedThread(threading.Thread):def__init__(self):
        super(DebuggedThread, self).__init__()
        self._real_run = self.run
        self.run = self._debug_run
    def_debug_run(self):
        # initialize debugger hereself._real_run()

threading.Thread = DebuggedThread
