Monitoring blocking time within event loop with set_debug() doesn't work

[temeddix]

When using asyncio, we can find the blocking code like this:

import asyncio
import time


async def main():
    time.sleep(1)  # Block event loop

if __name__ == "__main__":
    loop = asyncio.get_event_loop()
    loop.set_debug(True)  # Enable debug
    loop.slow_callback_duration = 0.1
    loop.run_until_complete(main())

Executing <Task finished coro=<main() [...]> took 1.016 seconds

However, when using qasync, no output is printed even if there's blocking inside the event loop. I'm using macOS on Apple Silicon.

from qasync import QEventLoop
import time


async def main():
    time.sleep(1)  # Block event loop

if __name__ == "__main__":
    ...
    loop = QEventLoop(app)
    loop.set_debug(True)  # Enable debug
    loop.slow_callback_duration = 0.1
    loop.run_until_complete(main())
