charset="utf-8" allow resolve_type to be used for both built-in and user-specified type definitions. In the event that the type cannot be resolved, assert that 'info' and 'what' were both provided in order to create a usable QAPISemError. In practice, 'info' will only be None for built-in definitions, which *should not fail* type lookup. As a convenience, allow the 'what' and 'info' parameters to be elided entirely so that it can be used as a can-not-fail version of lookup_type. Note: there are only three callsites to resolve_type at present where "info" is perceived to be possibly None: 1) QAPISchemaArrayType.check() 2) QAPISchemaObjectTypeMember.check() 3) QAPISchemaEvent.check() Of those three, only the first actually ever passes None; the other two are limited by their base class initializers which accept info=3DNone, = but neither actually use it in practice.
