[New-bugs-announce] [issue14073] allow per-thread atexit()

[Tarek Ziadé]

New submission from Tarek Ziadé <ziade.tarek at gmail.com>:

If you try to run the code below and stop it with ctrl+C, it will lock because atexit is never reached.

Antoine proposed to add a way to have one atexit() per thread, so we can call some cleanup code when the app shuts down and there are running threads.


{{{
from wsgiref.simple_server import make_server
import threading
import time
import atexit


class Work(threading.Thread):
    def __init__(self):
        threading.Thread.__init__(self)
        self.running = False

    def run(self):
        self.running = True
        while self.running:
            time.sleep(.2)

    def stop(self):
        self.running = False
        self.join()

worker = Work()


def shutdown():
    # bye-bye
    print 'bye bye'
    worker.stop()


atexit.register(shutdown)


def hello_world_app(environ, start_response):
    status = '200 OK' # HTTP Status
    headers = [('Content-type', 'text/plain')]
    start_response(status, headers)
    return ["Hello World"]

def main():
    worker.start()
    return make_server('', 8000, hello_world_app)

if __name__ == '__main__':
    server = main()
    server.serve_forever()
}}}
