Executing scripts and reading stdout/stderr is probably too low-level. I think we need a Python/Twisted (or whatever language Torperf will be written in) interface for running an experiment and retrieving results.
You're probably right on stdout/err being too low level, but most
experiments would be reusing the provided implementation, just wrapping them in a simple manner. Anyway I think there's a language agnostic way to get this working, without forcing any extensibility on matching Torperfs language of choice. I've tried to be pretty generic in my attached changes. :)
Well, thanks for your input! As I said above, it would help a lot if you added these ideas to the appropriate sections of the design document.
Please see attached.
