Python 3.3.4: python-daemon-3K ; How to use runner -

struggling try , python daemon work using python 3.3.4. im using latest version of python-daemon-3k pypi i.e. 1.5.8

starting point following code found how create daemon in python? code believe 2.x python.

import time daemon import runner  class app():     def __init__(self):         self.stdin_path = '/dev/null'         self.stdout_path = '/dev/tty'         self.stderr_path = '/dev/tty'         self.pidfile_path =  '/tmp/foo.pid'         self.pidfile_timeout = 5     def run(self):         while true:             print("howdy!  gig'em!  whoop!")             time.sleep(10)  app = app() daemon_runner = runner.daemonrunner(app) daemon_runner.do_action() 

attempting run following error.

python mydaemon.py start
traceback (most recent call last): file "mydaemon.py", line 60, in daemon_runner = runner.daemonrunner(app) file "/depot/python-3.3.4/lib/python3.3/site-packages/python_daemon_3k-1.5.8-py3.3.egg/daemon/runner.py", line 89, in init app.stderr_path, 'w+', buffering=0) valueerror: can't have unbuffered text i/o

any pointer how translate work python 3.3.4 or example of using runner in python-daemon-3k

thanks derek

to make code run in python3 need make change in daemonrunner class, cannot have unbuffered text io can have unbuffered bytes io changing mode to'wb+' work:

class daemonrunner(object):          self.parse_args()         self.app = app         self.daemon_context = daemoncontext()         self.daemon_context.stdin = open(app.stdin_path, 'r')          # linux /dev/tty must opened without buffering , b         self.daemon_context.stdout = open(app.stdout_path, 'wb+',buffering=0)         # w+ -> wb+         self.daemon_context.stderr = open(             app.stderr_path, 'wb+', buffering=0)
