我的脚本很好地记录到一个文件中,直到我尝试将它分叉到后台,此时文件句柄被关闭,即使我使用 filesPreserve。如何以轻量级的方式改进这一点,以便我的记录器在后台运行?

context = daemon.DaemonContext()
logger = logging.getLogger('audit')
hdlr = logging.FileHandler('/mnt/audit.log')
formatter = logging.Formatter('%(asctime)s %(message)s')
hdlr.setFormatter(formatter)
logger.addHandler(hdlr)
logger.setLevel(logging.WARNING)
context.filesPreserve = [hdlr]
with context:
HOST = ''

serv.bind((ADDR))
serv.listen(5) #5 is the maximum number of queued connections we'll allow
while True:
conn, addr = serv.accept()
sys.stdout.write('accepted connection')
while True:
data = conn.recv( 1024 )
if not data:
break
else:
logger.error ("-" * 20)
logger.error(data)
if "DONE" == data:
break
conn.close()
