Permission denied on config.lock when cloning in Docker under MacOS · Issue #1566 · gitpython-developers/GitPython (original) (raw)

Hi,
I found a bug related to the FileLock system. What I'm doing:

Exception in thread my-repository:
Traceback (most recent call last):
  File "/usr/local/lib/python3.8/dist-packages/git/util.py", line 941, in _obtain_lock_or_raise
    fd = os.open(lock_file, flags, 0)
PermissionError: [Errno 13] Permission denied: '/work/repo/my-repository.git/.git/config.lock'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):

I will provide a minimum set-up (docker file and python script) to reproduce it later.
