Solution was quite easy. Thanks to the user reply here: beehaw.org/comment/3535588 or programming.dev/comment/10034690 (Not sure if the links actually work as expected...)
Hi all. I have a little problem and don't know how to solve. A CLI program in Python is broken since Python 3.12. It was working in Python 3.11. The reason is, that Python 3.12 changed how subclassing of a pathlib.Path works (basically fixed an issue), which now breaks a workaround.
The class in question is:
class File(PosixPath):
def __new__(cls, *args: Any, **kwargs: Any) -> Any:
return cls._from_parts(args).expanduser().resolve() # type: ignore
def __init__(self, source: str | Path, *args: Any) -> None:
super().__init__()
self.__source = Path(source)
@property
def source(self) -> Path:
return self.__source
@property
def modified(self) -> Time:
return Time.fromtimestamp(os.path.getmtime(self))
@property
def changed(self) -> Time:
return Time.fromtimestamp(os.path.getctime(self))
@property
def accessed(self) -> Time:
return Time.fromtimestamp(os.path.getatime(self))
# Calculate sha512 hash of self file and compare result to the
# checksum found in given file. Return True if identical.
def verify_sha512(self, file: File, buffer_size: int = 4096) -> bool:
compare_hash: str = file.read_text().split(" ")[0]
self_hash: str = ""
self_checksum = hashlib.sha512()
with open(self.as_posix(), "rb") as f:
for chunk in iter(lambda: f.read(buffer_size), b""):
self_checksum.update(chunk)
self_hash = self_checksum.hexdigest()
return self_hash == compare_hash
and I get this error when running the script:
Traceback (most recent call last):

AttributeError: type object 'File' has no attribute '_from_parts'. Did you mean: '_load_parts'?
Now replacing _from_parts with _load_parts does not work either and I get this message in that case:

I have searched the web and don't understand how to fix this. Has anyone an idea what to do?
