I do have a decorator for exactly that purpose in my code. Here it is:
def on(sig):
'''
A factory of decorators for signal handlers. An example of usage
is
@on(signal.SIGTERM)
def termination(frame):
print 'sent SIGTERM'
raise SystemExit
Code calling termination.signal() will send a SIGTERM signal to
the
main thread, which in turns will call the termination handler,
which
will print a message and raise SystemExit.
'''
def handler_decorator(handler):
'Install the handler and add a .signal function attribute to
it'
signal.signal(sig, lambda signum, frame : handler(frame))
handler.signal = lambda : os.kill(os.getpid(), sig)
return handler
return handler_decorator
