Ping me when you get to that point - it is now possible to use python.exe + a 'bootstrap' script to host services - it is just that I haven't made the transition from pythonservice.exe to a more stand-alone environment. Cheers, Mark This sounds intriguing...where can I find out more about this? I'm apparently unable to figure out the right Google keywords, and I don't see anything in the changelog...
This happened quite some years ago now. Back when service support was first created, there was a pseudo-module named 'servicemanager' which pythonservice.exe magically exposed (ie, it was "builtin" to pythonservice.exe). Since then the module has been made a "real" module *ie, servicemanager.pyd now exists) which exposes everything necessary to host services - which means that it is possible, although not actually implemented, that the service could be hosted by python.exe which uses the service manager module.
The main advantage pythonservice.exe still has though is more robust error reporting - should things fail in a bad way, pythonservice.exe can write errors directly to the windows event log (ie, without importing any python modules to do so). On the other hand, python.exe will be unable to be so robust - if the environment is so messed up that the core python modules can't be imported (eg, win32evtlog, ctypes, etc) there is not much they can do to expose the error in a reasonable way. This is the reason I've never dropped support for pythonservice.exe and also the reason I've never bothered to make a real "driver" script for python.exe - one more thing to support and have people expect to work. That said though, my experience with services is that it is fairly rare such a low-level environment error actually occurs, so in most cases, python.exe could report the same errors just fine....
