Richard van der Hoff 8dd3c182ee Make space in the session pickle for chain index ... Keeping track of the chain index is a useful thing to do, but is only required if we've enabled diagnostics. Extend the session pickle format to make a space for it, so that pickles can be transferred between the logging_enabled branch and the master branch without loss of information. Also add some tests for session pickling which explicitly check that we can unpickle both formats of pickle.		2016-06-30 11:38:01 +01:00
