[Mono-devel-list] System.ServiceProcess (RE: [Mono-list] services and daemons)

I've done a little proof of concept to run services under Mono/Linux.
The attached test program (quick and dirty!) is a little daemon
embedding Mono. It is able to instantiate a class based on ServiceBase
and calls the On... functions. It is controlled using signals.

How to test the sample:
- Apply supplied patch to System.ServiceProcess.ServiceBase
- Build the samples
- Run test daemon
	testdaemon testservice.exe TestService TestService
- Pause
	kill -USR1 `cat /tmp/testdaemon.lock`
- Continue
	kill -USR2 `cat /tmp/testdaemon.lock`
- Stop
	kill `cat /tmp/testdaemon.lock`

It's my first embedded Mono app so please be forgiving ;-)

Known problems:
- Entry point of service will not be called
- Infrastructure of namespace System.ServiceProcess is not used
  except of class ServiceBase
- Rudimental error and exception handling
- Only one service can be started in parallel
- CanPauseAndContinue is ignored
- Main thread is polling for signals
- Service class is not checked to be a child of ServiceBase
- ...

Any comments are highly appreciated!
