Cancel a streaming response with only one shutdown (CTRL+C) signal

[Khumain]

Hello everyone,

I am working with FastAPI and Server Sent Events and I am encountering the very known issue regarding the need of sending 2 SIGINT signals to close pending HTTP connections :
Waiting for background tasks to complete. (CTRL+C to force quit)
However, I would like to interrupt the program with only 1 SIGINT. I have looked through the internet for solutions but could not find what I was looking for unfortunately ( #451 ).

A commit got my attention because it could possibly solve the problem of Uvicorn waiting for a second SIGINT to interrupt HTTP connections : #1092 . It was never merged but a timeout could be a nice workaround.

Is there any other solution I can use with FastAPI?

Thank you so much for your help.
