Request additional time when stopping a windows service about cx_freeze

[marcelotduarte]

In c# one can call RequestAdditionalTime() function, to keep the windows happy while the service is stopping. Can this be somehow be achieved in cx_freeze generated windows services?

We can implement this. Can you do it (if you use C) or at least find the equivalent function in C so I can implement it?

Unfortunately I'm not a C programmer.

But i guess the equivalent functionality could be achieved by calling SetServiceStatus with value of SERVICE_STOP_PENDING repedately.

I have since implemented my service using the win32service library, and doing this works:

while has_running_tasks():
	logger.info("Waiting for still running tasks to finish")
	time.sleep(5)
	self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)

The windows still will report that the service "did not stop in a timely manner" (but will take more time than normally), and will not kill it forcefully, allowing the service to stop properely (i had one taks that took additional 30 minutes to complete after asking windows to stop the service and the task finished normally and then the service did stop).
