[python-win32] manipulating service action restart behavior?

[Andrew Hammond]

I did some more hunting around and now have the following:

hscm =
win32service.OpenSCManager(None,None,win32service.SC_MANAGER_ALL_ACCESS)
try:
    hs = win32serviceutil.SmartOpenService(hscm, cls._svc_name_,
win32service.SERVICE_ALL_ACCESS)
    try:
        service_failure_actions = {
            'ResetPeriod': 6000000,   # Time in seconds after which to reset
the failure count to zero.
            'RebootMsg': '',
            'lpCommand': '',
            'Actions': [(win32service.SC_ACTION_RESTART, 60000),
(win32service.SC_ACTION_RESTART, 60000)]
        }
        win32service.ChangeServiceConfig2(hs,
win32service.SERVICE_CONFIG_FAILURE_ACTIONS, service_failure_actions)
    finally:
        win32service.CloseServiceHandle(hs)
finally:
    win32service.CloseServiceHandle(hscm)

However, I'm getting the following error message:

TypeError: SERVICE_FAILURE_ACTIONS must be a dictionary containing
{'ResetPeriod':int,'RebootMsg':unicode,'lpCommand':unicode,'Actions':sequence
of 2 tuples(int,int)

Which I think is what I'm feeding it. Can someone please tell me what I'm
doing wrong?
