Glyph, I've got the service up and running, but it doesn't do anything. All I want to do is make a twisted web application that listens on port 8080 and serves files out of c:\web -- or better yet, it would be nice if I could simply instantiate the web.tap file just as I would using "twistd -f web.tap". I'm willing to get under the hood and make this happen, but unfortunately I'm under a bit of a time constraint. I've been RTFM'ing all morning, but the documentation is scattered, and I am a bit green in the realms of asynchronous server programming, and have been coding in python for less than a week. Could you advise me as to what direction to take in instantiating a twisted web application from within the service? I was thinking of simply importing twisted.py, but I can't figure out how to make it run with options I dictate programatically, than the system command line switches. Once I've figured this out, I'll be sure to post the full source, so others may benefit. Here's the basic service, almost Identical to the one Bob posted, though I had to import twisted.internet.reactor to get it to work. import win32serviceutil import win32service import win32event class KAQueryService(win32serviceutil.ServiceFramework): _svc_name_ = "KAQueryService" _svc_display_name_ = "Kinematic Query Service" def __init__(self, args): win32serviceutil.ServiceFramework.__init__(self, args) self.hWaitStop = win32event.CreateEvent(None, 0, 0, None) def SvcStop(self): self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING) win32event.SetEvent(self.hWaitStop) def SvcDoRun(self): from twisted.python.log import startLogging # we don't have the console, so we log somewhere # the NT service logging facilities probably isn't the right place startLogging(open('c:/twistedexample.log','a')) self.CheckForQuit() startTwisted() def CheckForQuit(self): from twisted.internet import reactor #print "Check For Quit" rv = win32event.WaitForSingleObject(self.hWaitStop, 10.0) if not rv == win32event.WAIT_TIMEOUT: print "Received Quit from Win32" reactor.stop() reactor.callLater(1.0, self.CheckForQuit) def startTwisted(): from twisted.internet.app import Application #How do I specify a port or load a tap file? app = Application("web") app.run(save=0) print "Finished" if __name__=='__main__': # you could call startTwisted to run as not-a-service # or use it for cross-platform reasons win32serviceutil.HandleCommandLine(KAQueryService) -----Original Message----- From: Glyph Lefkowitz [mailto:glyph@twistedmatrix.com] Sent: Wednesday, March 05, 2003 11:15 AM To: twisted-python@twistedmatrix.com Subject: Re: [Twisted-Python] NT Service -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On Wednesday, March 5, 2003, at 12:41 PM, Bob Ippolito wrote:
I'm assuming you've already RTFM'ed about win32all's win32service and Twisted. Here's a stripped example of what has worked very well for me for the few times I was forced to deploy under Windows:
It would be really great if someone could genericize this and create a version that had a configuration dialog that allowed you to select a particular .tap file to load, rather than instantiating the Application inline. That way deploying on Win32 would be much more directly analagous to deploying on unix. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (Darwin) iD8DBQE+Zky+vVGR4uSOE2wRAqdLAJ9+KogR9IgvsEwlyhVJT4FQhBQVlQCfdkOL c7FtjeYrzf8H0fZuNz6mGi4= =oWYP -----END PGP SIGNATURE----- _______________________________________________ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python

mktap does the bit of code where you create the Site and File instances and call listenTCP. A good goal for making twisted better on windows (low on most priority lists since most of the twisted developers don't use windows) would be some sort of way to say "install this TAP as a service" which basically runs all that boilerplate; I have no idea about any of the details of how this would work though. Hope this helps. Donovan
Whoops, typo in my code. Sorry. On Wednesday, March 5, 2003, at 01:18 PM, Donovan Preston wrote:
