It could probably be done with something like a "twistd
--nt-service" option for Win32, perhaps?  Hmm, except you
need to register services.

I think a "twistd --register-nt-service" option could work,
and then you'd just let the user run it using the normal NT
service management utils.  It should probably have an
--unregister-nt-service, too.

I'd volunteer to develop this, but I don't have access to
WinNT anymore.

Actually, perhaps a "tap2ntsvc" (similar to tap2deb, etc) is
a better idea than hacking this onto twistd?

comment:3 Changed 17 years ago by itamarst

hmmm. I suppose it depends exactly how NT services are
expected to work. And how would we integrate this with
py2exeish things?

comment:4 Changed 17 years ago by itamarst

We now have a twistw. This should probably go there in some
form.

just my 2 cents, cygwin has 'cygrunsrv' which allows setup, removal, starting,
and stopping of programs (exe's, shell-scripts, whatever) as windows nt
services. this information may be of some use to whoever decides to attack this
problem

(Nosy myself.)

I second spiv's notion of tap2ntsvc. 

Services are fundamentally an install-time thing, whereas twistd is a runtime
thing.  As I see it, "twistw"'s role should just be to invoke pythonw.exe
instead of python.exe so that the process doesn't have a terminal.

If you use tap2ntsvc, you're taking the startup completely out of twistd/twistw
space and putting it into Windows space, but this is how Windows makes you do
things.

comment:7 Changed 16 years ago by itamarst

There is no twistw as such right now - it's merely the script that
scripts/twistd.py calls on windows. There is of course a need for something that
uses pythonw.exe.

Anyway, tap2ntsvc.... that's actually probably pretty easy to write. And it
could easily have a switch for making a .exe using py2exe.

MoonFallen is working on this in his sandbox:

sandbox/moonfallen/tap2ntsvc.py

He seems to have some grand plans for it.

comment:9 Changed 15 years ago by radix

this is implemented, afaik. resolving.

comment:10 Changed 15 years ago by Cory Dodt

There's only some stuff in the sandbox with more work to do.  Re-opening, ->
in-progress.

See sandbox/moonfallen/TODO.txt for details.

Any chance of getting this code out of the sandbox and into the real world?

I guess this is related to #2646 -- "twistd should write a pidfile on win32" -- and perhaps to [6678] and [17973].

Adding my 2c; I played around with ntsvc and twistd a while ago and it wasn't a fruitful experience. The service didn't start, or register, or something like that. Whatever the approach, it definitely should work with py2exe -- running an exe as the service rather than a batch file or .py or whatever is always going to be more desirable.

ntsvc isn't that fancy, and it's pretty easy to implement a fully functioning Win32 service with all the bells and whistles with a reasonable amount of pywin32 code.

i used twisted for my windows services, the best and easiest way is just to use the pythonservice.exe that comes with pythonwin. Works perfectly. In fact pythonservice.exe should and can be used for creating any python services for windows.It runs on 32bit Xp,Vista,Win 2000, 2003, windows 7, Win 2008 and 64 bit also.

Just fill up the "SvcDoRun" and "SvcStop". See a real example below. In my example smtpserver._main(xxx) starts the reactor.

def SvcStop(self):

# Before we do anything, tell the SCM we are starting the stop process. self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING) self.stop = True smtpserver.reactor.stop() # And set my event. win32event.SetEvent(self.hWaitStop) win32api.Sleep(1000)

def SvcDoRun(self):

if smtpserver._main(None, None, service=True) :

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

if name=='main':

win32serviceutil.HandleCommandLine(PythonService)
