Hi all
It is easy enough to set up a task to run in the background every 10 seconds
using asyncio -
async def background_task():
while True:
await perform_task()
await asyncio.sleep(10)
asyncio.ensure_future(background_task())
When shutting the main program down, I want to stop the task, but I cannot
figure out how to stop it cleanly - i.e. wait until it has finished the
current task and possibly performed some cleanup, before continuing.
async def background_task():
await perform_setup()
while condition:
await perform_task()
await asyncio.sleep(10)
await perform_cleanup()
Previously I would run the task in another thread, then set a flag to tell
it to stop, then join() the thread which would block until the task had
finished. I used threading.Event as the flag, which allows it to 'sleep'
using wait() with a timeout value, but reacts instantly when set() is
called, so it was ideal.
Is there a way to achieve this using asyncio?
Thanks
Frank Millman
