python 3.x FreeBSD 11.3-RELEASE-p12 with custom settings mentioned later. On vanilla configuration of FreeBSD there is no issue. Installation of FreeBSD in question has mac_bsdextended turned on (https://www.freebsd.org/cgi/man.cgi?query=mac_bsdextended&sektion=4&apropos=0&manpath=FreeBSD+12.1-RELEASE+and+Ports) Using ugidfw (https://www.freebsd.org/cgi/man.cgi?query=ugidfw&sektion=8&manpath=freebsd-release-ports), the following rule has been set: --------------------------------------------------------------- 0 subject not uid root gid nobody object gid wheel type d mode sx --------------------------------------------------------------- The following code shows the minimal reproducible example: --------------------------------------------------------------- from pathlib import Path BASE_DIR = Path(__file__).resolve(strict=True).parent.parent print(BASE_DIR) --------------------------------------------------------------- Running the code directly works: --------------------------------------------------------------- $ python test.py /usr/home/example --------------------------------------------------------------- But importing it as a module does not: --------------------------------------------------------------- $ python -m test Traceback (most recent call last): File "/usr/local/lib/python3.6/runpy.py", line 193, in _run_module_as_main "__main__", mod_spec) File "/usr/local/lib/python3.6/runpy.py", line 85, in _run_code exec(code, run_globals) File "/usr/home/example/django_3136test/test.py", line 2, in <module> BASE_DIR = Path(__file__).resolve(strict=True).parent.parent File "/usr/local/lib/python3.6/pathlib.py", line 1141, in resolve s = self._flavour.resolve(self, strict=strict) File "/usr/local/lib/python3.6/pathlib.py", line 346, in resolve return _resolve(base, str(path)) or sep File "/usr/local/lib/python3.6/pathlib.py", line 330, in _resolve target = accessor.readlink(newpath) File "/usr/local/lib/python3.6/pathlib.py", line 440, in readlink return os.readlink(path) PermissionError: [Errno 13] Permission denied: '/usr' --------------------------------------------------------------- The issue seems to be comnected with following piece code https://github.com/python/cpython/blob/master/Lib/pathlib.py#L342-L346 --------------------------------------------------------------- try: target = accessor.readlink(newpath) except OSError as e: if e.errno != EINVAL and strict: raise # Not a symlink, or non-strict mode.
