Re: [ros-kernel] Service.exe

[Jarmo M. <ja...@mu...>]

Hello,

I think that you both can implement pieces of the services at the
same time. I have some knowledge of services. I see services as
following classes (I'm OO designer/programmer):

- Service Control Program (SCP)
- Service Control Manager Client (SCMC)
- Service Control Manager Server (SCMS)
- Service Process (SP)

Service Control Program is the Services applet. This is clearly
the easiest module to implement.

Service Control Manager Client is the module which SCP uses and
it's in advapi32.dll. This module implements client part. SCMC
connects to SCMS by named pipe.

Service Control Manager Server is the module where SCMC connects
to and it's in services.exe. This module implement server part.
SCMS starts the Service Process and creates a thread for service
when the service is started.

Service Process uses advapi32.dll too, but uses different APIs
that SCP.

One of the most difficult part, to me, is the pipe. What is the
protocol?

So, one could implement SCP, one could write both ends of the
pipe, one could write SCMC and one could write SCMS. This could be
easily splitted for four developers.

At point I thought that I could implement them, but I don't have
time. I checked ReactOS code and noticed that it wasn't
implemented "at all". The code that were implemented started all
services in the process at the same time. That's wrong.
