uvicorn is not checking occupied ports

[mhechthz]

I wonder why uvicorn on calling from within python

uvicorn.run("mywebapp:app",host="0.0.0.0",port=port,reload=True)

is not checking if the port is already occupied or blocked or not.

I' m forced to run something like this:

def check_port(port,host="0.0.0.0",do_exit=True):

    with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:
        if do_exit:
            print(f"port {port} already in use ... exit ...")
            time.sleep(10)
            sys.exit()
        else:
            return False
return True

wich is totally inconvenient, since one obviously wants a message if runnig uvicorn will not be successsful.

Is there any chance to do this with uvicorn, e.g with an option like checkport=True?

What do you mean by "is not checking"?

It's doing that...
