MeasurementLink Support for Python v1.2.0

What's Changed

• Added support for service annotations (#291 #294 #296 #338)
  • The .serviceconfig file now supports specifying additional information about the measurement via the annotations dictionary.
  • Example:

    "annotations":
    {
      "ni/service.description": "Measure inrush current with a shorted load.",
      "ni/service.collection": "CurrentTests.Inrush",
      "ni/service.tags": [ "powerup", "current" ]
    }
  

  • ni-measurementlink-generator now supports generating the annotations dictionary. By default, it sets ni/service.description, ni/service.collection, and ni/service.tags to empty values. You can specify values with the --description, --collection, and --tags command line options.
• Added support for protobuf enums (#328)
  • The protobuf generated code for enums does not use the Python enum module. Instead, it uses integers and provides a subclass of EnumTypeWrapper describing the enum value mapping.
  • When you use the configuration and output decorators to specify measurement parameters, you can now specify either an enum.Enum subclass or an EnumTypeWrapper instance for enum_type.
• Support for Python services returning DoubleXYData
  • Add encoder and decoder for DoubleXYData (#358)
  • Game of Life example (#360)

  • Importing nidcpower.session into output voltage measurement (#399)
  • Fix pywintypes error during the launch of the discovery service after a fresh install of MeasurementLink (#407)
  • Update reserve_session to roll back on error (#401)
