Class Client

source code

RPC Client class.

This class, given a (remote) method name, a list of parameters and a list of nodes, will contact (in parallel) all nodes, and return a dict of results (key: node name, value: result).

One current bug is that generic failure is still signaled by 'False' result, which is not good. This overloading of values can cause bugs.
