WTF? How am I supposed to end the app gracefully with interrupt signal if Remi is just another user interface (it has physical buttons)?\n\nThe remi package (`__init__.py`) even imports a special function for starting the server:\n```\nfrom .server import App, Server, start\n```\nBut apparently there is absolutely no interface for stopping it. Why?\n\nI've found this old bug report where a functional solution was proposed but the report was closed for no reason: https://github.com/rawpython/remi/issues/274#issuecomment-457251735\n\nSo, if one has an instance of such a `MyApp`, they can do this:\n```\n        my_app = MyApp()\n        def interrupt_handler():\n            my_app_instance.server.server_starter_instance._alive = False\n            my_app_instance.server.server_starter_instance._sserver.shutdown()\n            return signal.SIG_DFL\n        remi.start(my_app, ...)\n        signal.signal(signal.SIGINT, interrupt_handler)\n```\nor they have to implement such a handler into their `MyApp`.","author":{"url":"https://github.com/kyselejsyrecek","@type":"Person","name":"kyselejsyrecek"},"datePublished":"2025-06-04T15:26:25.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/549/remi/issues/549"}
