[RFC PATCH 0/1] Don't use set() for datastore variables

[Joshua Lock <josh@linux.intel.com>]

This is an RFC patch.

I recently implemented a check within the hob gui to ensure that it's running with the
required pre and post configuration files. However this check uses a variable from the data
store which is a Python set container.

The Python xmlrpclib is unable to marshal sets and therefore the patch I added breaks hob
when using the xmlrpc server backend.

I've assumed that storing variables in the datastore that cannot be accessed using the
getVariable API with each of our servers is a bad thing and the attached patch changes the
use of set to a dict.

There are, of course, alternative workarounds for this issue. For example, we could create a
new variable to list file dependencies, but that seems a little wasteful? Or we could add
some logic to the xmlrpc server to ensure it doesn't try and marshal unsupported types?

Comments?

Joshua
