问我在"syslog-ng -Fevd“中运行的嵌入式Python似乎没有接收到信号，是真的吗？

EN

#Start of syslog-ng python config
python {

def handler(signum, frame):
    print 'Signal handler called with signal', signum
    stopSubscription()

signal.signal(signal.SIGALRM, handler)
signal.signal(signal.SIGINT, handler)
signal.signal(signal.SIGABRT, handler)
signal.signal(signal.SIGHUP, handler)
signal.signal(signal.SIGTERM, handler)
signal.signal(signal.SIGBUS, handler)
signal.signal(signal.SIGCHLD, handler)
signal.signal(signal.SIGCLD, handler)

def stopSubscription():
    print "shutdown requested"
}; # end of syslog-ng block
