Re: SystemTapGui usage scenarios.

Hi Dave,

I'm not very clear with the usage of stap-server/stap-server that you have described.
This is what i understood:
The staprun-server(stapgui-server/"lean" server) is to staprun what the stap-client/stap-server is to stap.
Yes.
1. In a scenario where i create a script using stapgui, and i need to execute it on a remote machine - i use stap-client to create the module and use the staprun-server("lean" server) to execute the module.
Yes.
2. In a scenario where i create a script using stapgui, and i need to execute on the same machine - i use stap and staprun instead of the stap-client and staprun-server
Yes.

The problem i have with this is that it creates a "hard-dependency", in the sense , in scenario 1 if there is no stap-server the stapgui cannot be used. I would like to use stapgui even if there is no registered compile-server.


The alternative would be to check if there is a registered compile-server, if not use stap to compile on the remote machine and use the staprun-server for execution. This is how others had interpreted you mail :).
Yes. The idea is that we can minimize the amount of duplicated functionality among our tools. However, if there is no stap-server available to remote compilation, then stapgui-server would then be forced to use stap to do the compilation.
