Windows Service wasn't able to stop

[Picoman Yang]

• Expected behavior and actual behavior.
  The service should be able to start and stop.

• Steps to reproduce the problem.

• Version of Python and pywin32
  Python: 3.11.6
  OS: Windows Server 2022
  pywin32: 306

The program is the following:

"""
Log masking main program entry point.

usage:

python main.py -c {config.json}
"""
import sys
import servicemanager
import win32service
import win32serviceutil
from log_watch import LogObserver


class LogMaskSvc(win32serviceutil.ServiceFramework):
    _svc_name_ = "BBA Log mask"
    _svc_display_name_ = "BBA Log mask"
    _svc_description_ = "Mask GPS data in DLT or ASC files"

    def __init__(self, args):
        win32serviceutil.ServiceFramework.__init__(self, args)
        self.ssh = None
        self.__log_observer = None

    def SvcDoRun(self):
        self.ReportServiceStatus(win32service.SERVICE_START_PENDING, waitHint=3000)
        self.__log_observer = LogObserver(config='D:\log_mask\config.json')
        self.ReportServiceStatus(win32service.SERVICE_RUNNING, waitHint=3000)
        self.__log_observer.run()

    def SvcStop(self, control):
        self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING, waitHint=3000)
        self.__log_observer.stop()
        self.ReportServiceStatus(win32service.SERVICE_STOPPED, waitHint=3000)


if __name__ == '__main__':
    win32serviceutil.HandleCommandLine(LogMaskSvc)

The Service status is:

SERVICE_NAME: BBA Log mask
DISPLAY_NAME: BBA Log mask
        TYPE               : 10  WIN32_OWN_PROCESS
        STATE              : 2  START_PENDING
                                (NOT_STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN)
        WIN32_EXIT_CODE    : 0  (0x0)
        SERVICE_EXIT_CODE  : 0  (0x0)
        CHECKPOINT         : 0x0
        WAIT_HINT          : 0x1388

There's probably an exception being thrown somewhere in your service. See https://github.com/mhammond/pywin32#support for one way of getting help using pywin32.
