I have created a quixote program which I like to run as service on windows
machine using either medusa or twisted matrix as web server.
I am having trouble with both of them. Am I missing something or I have to run
it with IIS or Apache?



When I run quixote.demo (quixote 0.7a3) with medusa server as a win32 service as
follows:

import win32serviceutil
import win32service
import win32event

class motorService(win32serviceutil.ServiceFramework):
    _svc_name_ = "motorService"
    _svc_display_name_ = "The Motor Service"
    def __init__(self, args):
        win32serviceutil.ServiceFramework.__init__(self, args)
        #self.hWaitStop = win32event.CreateEvent(None, 0, 0, None)

    def SvcStop(self):
        pass
       # self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
       # win32event.SetEvent(self.hWaitStop)

    def SvcDoRun(self):
        import asyncore
        from quixote.server.medusa_http import http_server, QuixoteHandler
        from quixote import enable_ptl
        from quixote.publish import Publisher
        enable_ptl()
        server = http_server.http_server('', 80)

        publisher = Publisher('quixote.demo')
        publisher.setup_logs()
        dh = QuixoteHandler(publisher, 'Quixote/demo', server)
        server.install_handler(dh)
        asyncore.loop()

        #win32event.WaitForSingleObject(self.hWaitStop, win32event.INFINITE)

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

It runs for some time and then stop running with following error in eventlog:

When I run with twisted as follows:

import win32serviceutil
import win32service
import win32event

class motorService(win32serviceutil.ServiceFramework):
    _svc_name_ = "motorService"
    _svc_display_name_ = "The Motor Service"
    def __init__(self, args):
        win32serviceutil.ServiceFramework.__init__(self, args)
        #self.hWaitStop = win32event.CreateEvent(None, 0, 0, None)

    def SvcStop(self):
        pass
       # self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
       # win32event.SetEvent(self.hWaitStop)

    def SvcDoRun(self):
        from twisted.internet.app import Application
        from quixote.server.twisted_http import QuixoteFactory
        import quixote
        quixote.enable_ptl()
        from quixote.publish import Publisher
        from twisted.python.log import startLogging
        startLogging(open('c:/twistedexample.log','a'))

        import quixote.demo
        http_port = 80
        namespace = quixote.demo

        app = Application('Quixote')
        publisher = Publisher(namespace)
        qf = QuixoteFactory(publisher)
        app.listenTCP(http_port, qf)
        app.run(save=0)


I got following error in twisted log file. I can not run demo at all using
twisted.
