| # Due to some incompatibilities between Python 2 and | ||
| # Python 3, there are some specific actions we take here | ||
| # to make sure the difflib.unified_diff call works. | ||
| # | ||
| # In Python 2, the call to subprocess.check_output return | ||
| # a 'str' type. In Python 3, however, the call returns a | ||
| # 'bytes' type unless the 'encoding' argument is | ||
| # specified. Unfortunately, the 'encoding' argument is not | ||
| # in the Python 2 API. We could do an if/else here based | ||
| # on the version of Python we are running, but it's more | ||
| # straightforward to read the file in binary and do utf-8 | ||
| # conversion. In Python 2, it's just converting string | ||
| # types to unicode types, whereas in Python 3 it's | ||
| # converting bytes types to utf-8 encoded str types. This | ||
| # approach ensures that the arguments to | ||
| # difflib.unified_diff are acceptable string types in both | ||
| # Python 2 and Python 3. | ||
