Description

Uvicorn 0.29.0 no longer captures, handles, and then surpresses SIGINT. Rather, SIGINT is repropagated by Uvicorn so we need to capture it again and pass. It is safe to pass because we let Uvicorn handle clean up for the endpoint.

Testing

I tested with this script on the old and new versions of uvicorn by starting the script and then sending each signal type with kill -s SIGTERM [PID].

import logging
import uuid

from proxystore.endpoint.config import EndpointConfig
from proxystore.endpoint.serve import serve

from testing.utils import open_port

logging.basicConfig()

config = EndpointConfig(
    name='test',
    uuid=str(uuid.uuid4()),
    host='localhost',
    port=open_port(),
)

serve(config, log_level='DEBUG')
