Hello, i have implemented a windows service in the past with python 2.7 and 3.7. I worked fine with this versions. Now I have to switch the version to 3.8. And with this environment, I have problems.
Below find the sourcecode for my implementation to install an run the service: #!/usr/bin/env python # -*- coding: utf-8 -*- """Run application as windows service Usage : python <script name>.py install Usage : python <script name>.py start Usage : python <script name>.py stop Usage : python <script name>.py remove Based on demos of Mark Hammond's pywin32 package and the following web sites: https://code.activestate.com/recipes/576451-how-to-create-a-windows-service-in-python/ http://www.codeproject.com/Articles/1115336/Using-Python-to-Make-a-Windows-Service """ import sys import servicemanager import win32serviceutil import win32event import app from app import config class SRMWindchillExportService(win32serviceutil.ServiceFramework): _svc_name_ = "PythonServiceTeset3.8" _svc_display_name_ = " PythonServiceTeset3.8" _svc_description_ = " PythonServiceTeset3.8" # Installation of service creates Windows System log event entry: # Source : ServiceControlManager # Event ID: 7045 def __init__(self, args): win32serviceutil.ServiceFramework.__init__(self, args) self.hWaitStop = win32event.CreateEvent(None, 0, 0, None) def SvcStop(self): win32event.SetEvent(self.hWaitStop) # Create Event Log entry: # Level: Information # Source: self._svc_name_ # Event ID: 4100 servicemanager.LogMsg(servicemanager.EVENTLOG_INFORMATION_TYPE, servicemanager.PYS_SERVICE_STOPPED, (self._svc_name_, '')) def SvcDoRun(self): # Create Event Log entry: # Level: Information # Source: self._svc_name_ # Event ID: 4098 servicemanager.LogMsg(servicemanager.EVENTLOG_INFORMATION_TYPE, servicemanager.PYS_SERVICE_STARTED, (self._svc_name_, '')) self.timeout = config.ServiceTimeout # time value in milliseconds msg = "Service: {0}\n" \ "------------------------------------------------------\n" \ "Repeating time: every {1} milliseconds.\n".format(self._svc_name_, self.timeout) servicemanager.LogInfoMsg(msg) application = app.Application() while 1: # Do the job. # If an exception occurs in app.run, the service would crash. # Therefore we have to catch all exceptions to ensure the # service keeps running. # In case of an exception write an error message to event log. try: application.run() except: # In case of any exception, report an error to event log, # but do not stopp the service! # Info is reported with "Source: _svc_name_" and Event ID: 255 servicemanager.LogErrorMsg("ERROR in {0}: {1}".format(self._svc_name_, sys.exc_info())) # Wait for service stop signal, if I timeout, loop again rc = win32event.WaitForSingleObject(self.hWaitStop, self.timeout) # Check to see if self.hWaitStop happened if rc == win32event.WAIT_OBJECT_0: # Stop signal encountered. Break the loop. break else: # Loop again pass if __name__ == '__main__': win32serviceutil.HandleCommandLine(SRMWindchillExportService) The problem occurs at the start of the service and shows the following errormessage: [cid:image001.png@01D5D5B1.D202E370] In the eventviewer are 3 events with error: [cid:image002.png@01D5D5B1.D202E370] For this error, I found a case at Microsoft: https://answers.microsoft.com/en-us/windows/forum/windows_10-security/event-id-10016-runtime-broker/18c291c6-f2a1-4f3c-b4ad-2b7ff59fd9f9?page=3 But this didn't help to solve the issue. Anyone have had this problem before? Thanks.
