Your example doesn't really make sense if the GET request is not async. This seems to work fine:
import asyncio
import httpx
from tqdm.asyncio import tqdm as tqdm_async
semaphore = asyncio.Semaphore(1)
x = 0
async def one_at_a_time():
global semaphore
async with semaphore:
global x
# await asyncio.sleep(1)
# httpx.get('http://httpbin.org/delay/1')
async with httpx.AsyncClient() as client:
await client.get('http://httpbin.org/delay/1')
x += 1
#print(x)
return x
await tqdm_async.gather(*[one_at_a_time() for _ in range(10)])
Thanks for the pointer @davidbrochart. I thought we'd get some parallelism with create_task
- but clearly that is incorrect since the blocking code does not return. Either way, I would still expect interrupt to have an effect.
FWIW, the above example was contrived since some API I use calls get
under the hood. I'll have to find a way to change that.
Hi,
Aside from the now fixed #881, I still run into some async + interrupt issues. I'm not 100% sure if I need to do something differently or there is a way to do what we mean.
The following is not interrupted and always run to completion. If you sleep instead of httpx.get (or request.get), it works as expected.
Ideally, I want these to be tasks so I can cancel them. Again, interrupt has no effect:
Any suggestions for how to fix my code to work better with ipykernel or how to fix ipykernel (or IPython) itself? Even better would be something that works on 6.x, but I think that may be challenging as even #881 is not fixed there.
