Bug 6565 - Feasibility of using the network-compiler server with the SystemtapGUI.

[anithra]

Hi Dave,

(Background: we're prototyping a compile server split of stap, to
allow a central network server to perform arbitrary script translation
and compilation for a machine without local debuginfo nor compiler.
It'll be useful later for unprivileged user-space probing too.  Some
prototype code is in bug #6565.)

This is Anithra from IBM, I'm currently looking to renew the Systemtap 
GUI project. (In case you are not familiar with the Systemtap GUI: It is 
an IDE and visualization tool for Systemtap. - 
http://sourceforge.net/projects/stapgui/  )

One of the new features that we wished to provide is 'remote execution', 
wherein a user could monitor a remote system located physically anywhere 
using the Systemtap GUI client. A typical scenario would be - The script 
is designed using the development environment provided by the Systemtap 
GUI, it is then pushed to a server which executes the script and returns 
the results to the client, allowing the user to therefore visualize the 
output with graphs.

 Your patch (bug #6565) seems very interesting in this regard. We were 
wondering if it would be possible to use the compiler server for this 
purpose, i.e, as the server for the Systemtap GUI. Please let me know 
your thoughts on this. The purpose of the SystemtapGUI server is 
slightly different from the compiler server, it would be to execute the 
script and return the results to the client, as opposed to returning the 
compiled module.

Regards,
Anithra.
