2016-10-24Make previous_uuid an input-only argument to hal_rpc_pkey_match().Rob Austein
In retrospect it's obvious that this never needed to be an input/output argument, as its value will always be the same as the last value in the returned array. Doh. So simplify the RPC and call sequence slightly by removing the unnecessary output value.
2016-10-21Tweak enum handling to handle more of the C enum definition syntax.Rob Austein
Intent is to make it easier just to paste C enum definitions into Python code and have the right thing happen, to simplify keeping C and Python definitions in sync.
2016-10-21Better enum handling, more readable RPC methods.Rob Austein
Using a context manager allows us to write the individual RPC methods fairly legibly, while still enforcing xdrlib.Unpacker.done() logic. Python doesn't really have enums in the sense that C does, and many people have put entirely too much skull sweat into trying to invent the Most Pythonic reimplementation of the enum concept, but an int subclass with a few extra methods is close enough for our purposes.
