Quick Start Tutorial - Finishing Issue

[DevPy129387]

• SPADE version: 3.3.2
• Python version: 3.11
• Operating System: Windows 10

Description

I did the second example in the Quick Start section of the documentation (An agent with a behaviour). It is stated, that "this agent would go on counting forever until we press ctrl+C.". But if I press Ctrl+C, the agent won't stop. It says "Keyboard interrupt received. Stopping SPADE..." but continues.

What I Did

import asyncio
import spade
from spade import wait_until_finished
from spade.agent import Agent
from spade.behaviour import CyclicBehaviour

class DummyAgent(Agent):
    class MyBehav(CyclicBehaviour):
        async def on_start(self):
            print("Starting behaviour . . .")
            self.counter = 0

        async def run(self):
            print("Counter: {}".format(self.counter))
            self.counter += 1
            await asyncio.sleep(1)

    async def setup(self):
        print("Agent starting . . .")
        b = self.MyBehav()
        self.add_behaviour(b)

async def main():
    dummy = DummyAgent("???", "???")
    await dummy.start()
    print("DummyAgent started. Check its console to see the output.")

    print("Wait until user interrupts with ctrl+C")
    await wait_until_finished(dummy)

if __name__ == "__main__":
    spade.run(main())

Output:

Agent starting . . .
DummyAgent started. Check its console to see the output.
Wait until user interrupts with ctrl+C
Starting behaviour . . .
