如何使用 GitPython 在提交中获取文件的源代码？

Question

I need to get source codes for all files in a commit. Currently I am using Pydriller and it works well. But for performance reasons I need to use GitPython. I have tried this solution:

repo = Repo('path to repo') )
    commit = repo.commit('my hash')
with io.BytesIO(target_file.data_stream.read()) as f: 
    print(f.read().decode('utf-8'))

But I get this error:

Traceback (most recent call last):
File "D:\Programmi\Python36\lib\threading.py", line 916, in _bootstrap_inner
    self.run()
File "D:\Programmi\Python36\lib\threading.py", line 864, in run
    self._target(*self._args, **self._kwargs)
File "D:/Workspaces/PythonProjects/fixing- 
    commit/crop_data_preparing_gitpython.py", line 82, in 
get_commit_data_gitpython
print(f.read().decode('utf-8'))
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x9f in position 18: invalid start byte

I have thought that this can be an encoding problem, but even changing the encoding from utf-8 to latin-1 doesn't help.

Does exist another strategy that would help me get the code for those files using GitPython?

As the first comment suggested, for these things I'd suggest you to use PyDriller , it's much easier:

for commit in RepositoryMining("repo").traverse_commits():
    for modified_file in commit.modifications:
        modified_file.source_code

It also takes care of decoding, renames, etc. You also have the source_code before the commit ( modified_file.source_code_before )
