Notifier restart

[mdabrowski1990]

Is your feature request related to a problem? Please describe.

After I call can.notifier.Notifier.stop not a Notifier object, there is no obvious way how to restart the Notifier.
As far as I see, I need to create a new notifier, which leads to another problem - if a Bus is added to two Notifiers (even if one of them is stopped) then an exception is raised by can.notifier._NotifierRegistry.register.

Describe the solution you'd like

I would like a restart method defined in Notifier class which would work exactly like I just created a new Notifier with the exactly the same settings as the existing one.

Describe alternatives you've considered

• can.notifier._NotifierRegistry.register does not raise an exception if another Notifier is stopped

[zariiii9003]

Notifier._registry.unregister(bus, self) is called at the end of Notifier.stop():

python-can/can/notifier.py

Line 219 in e3d2655

Notifier._registry.unregister(bus, self)

Did you get some exception before that line?

Edit: The exception is raised only if the Notifier is not stopped:

python-can/can/notifier.py

Line 58 in e3d2655

if bus is pair.bus and not pair.notifier.stopped:

Use Notifier.find_instances() to debug.

It is possible that exception with bus collision was my coding mistake.
Yet, I would appreciate you could add restart Notifier feature though.
