Question

I would like to embed the great Bottle web framework into a small application (1st target is Windows OS). This app starts the bottle webserver thanks to the subprocess module.

import subprocess
p = subprocess.Popen('python websrv.py')

The bottle app is quite simple

@route("/")
def index():
    return template('index')

run(reloader=True)

It starts the default webserver into a Windows console.

All seems Ok except the fact that I must press Ctrl-C to close the bottle webserver. I would like that the master app terminates the webserver when it shutdowns. I can’t find a way to do that (p.terminate() doesn’t work in this case unfortunately)

Any idea?

Thanks in advance

There are two ways to shutdown a reloading server:

1) You terminate p (using os.kill(p.pid) or p.terminate() ) and then change the modification time of ‘websrv.py’ (os.utime('websrv.py')) to trigger an automatic shutdown of the child process.

2) You terminate p with os.kill(p.pid, signal.SIGINT) which is identical to a Ctrl-C shutdown.
