How to stop event loop in child thread ?

I call the stop method in child thread，but loop’s state is running ~
Can you help me ?

import time
import asyncio
import threading
from functools import partial

import sanic
import uvloop


class ApiService:

    def __init__(self):
        self.__server = None
        self.__loop = None

    def _thread_main(self, loop):
        app = sanic.Sanic("Api")
        asyncio.set_event_loop(loop)
        serv_coro = app.create_server(
            host="0.0.0.0", port=8080, return_asyncio_server=True, debug=False
        )

        serv_task = asyncio.ensure_future(serv_coro, loop=self.__loop)
        self.__server = self.__loop.run_until_complete(serv_task)
        self.__server.after_start()
        self.__loop.run_forever()

    def run(self):
        self.__loop = uvloop.new_event_loop()
        # print(dir(self.__loop))
        # self._thread_main(self.__loop)
        thread = threading.Thread(
            target=partial(self._thread_main, self.__loop), name="api-service"
        )
        thread.setDaemon(True)
        thread.start()
        # thread.join()

    def stop(self):
        if self.__loop is None or self.__server is None:
            return

        self.__loop.stop()
        self.__server.before_stop()
        print(self.__loop)
        # Wait for server to close
        self.__loop.run_until_complete(self.__server.close())

        # Complete all tasks on the loop
        for connection in self.__server.connections:
            connection.close_if_idle()
        self.__server.after_stop()


if __name__ == '__main__':

    app = ApiService()
    try:
        app.run()
        while True:
            time.sleep(10)
    except (KeyboardInterrupt, InterruptedError) as _:
        print(app._ApiService__loop)
    except Exception as e:
        pass
    finally:
        app.stop()

• uvloop：0.14.0:
• python：3.7.2:
• MacOS10.15.7:

Commencez par reproduire l’interaction entre _thread_main, run_forever et stop avec l’environnement fourni composé de Python 3.7.2, uvloop 0.14.0 et macOS. Examinez les appels du cycle de vie de la boucle et du serveur présentés dans l’issue, puis vérifiez si l’arrêt depuis le thread parent se termine correctement. Documentez le comportement pris en charge ou la modification requise.
