[FIXED] Python asyncio sleep forever

Issue

In some test code I simulate a request handler coroutine that never returns a response. Below works by calling sleep with a sufficiently large value, but a better choice would be something like await asyncio.sleep_forever(). Is there anything built into python asyncio that can do this?

async def lagging_request_handler(request):
    await asyncio.sleep(10000)

Solution

You can await asyncio.Future() to make it run forever. It’s used in the websockets docs to serve forever: https://websockets.readthedocs.io/en/stable/
