wirerope and methodtools cause nuitka binary to fail.

Offending code is:

@classmethod
@lru_cache(maxsize=100)
def getPCellDef(cls, file_path: str) -> dict:
    try:
        with open(file_path, "r") as temp:
            return json.load(temp)
    except (json.JSONDecodeError, FileNotFoundError):
        return {}

I have seen a similar issue report from 2020 but that was closed because the python and nuitka versions were very old. In this case, they are fairly recent. In this case, the versions are the latest: Python 3.12 methodtools 0.4.5 wirerope 0.4.5 Nuitka 2.4

Latest for Nuitka is 2.4.8 actually and esp. for 3.12 that might mean a lot. This also lacks a self contained example that I could compile, or so it seems.

[eskiyerli]

Same with Nuitka 2.4.8 and python 3.12 in a virtual environment. As it is a part of large software, I need to think of a self-standing example. The whole repository is in revedaRelease.

[kayhayen]

I cannot execute unknown and therefore untrusted code easily, so I don't compile whole projects outside of paid for contracts, but the stack trace should allow you to easily come up with something.

[eskiyerli]

In that case, here is a small code that uses methodtools with lru_cache. I ran it with Nuitka 2.4.8 and Python 3.12. It still has the same problem:

from methodtools import lru_cache

class DataProcessor:
    @classmethod
    @lru_cache(maxsize=100)
    def process_data(cls, data):
        # Simulate a time-consuming operation
        result = sum(int(x) for x in data if x.isdigit())
        print(f"Processing data: {data}")
        return result

    @classmethod
    def display_cache_info(cls):
        print(f"Cache info: {cls.process_data.cache_info()}")

if __name__ == "__main__":
    # First call - will process the data
    result1 = DataProcessor.process_data("123abc456")
    print(f"Result 1: {result1}")

    # Second call with the same input - will use cached result
    result2 = DataProcessor.process_data("123abc456")
    print(f"Result 2: {result2}")

    # Call with different input - will process new data
    result3 = DataProcessor.process_data("789xyz")
    print(f"Result 3: {result3}")

    # Display cache information
    DataProcessor.display_cache_info()

Seems wirerope does a bunch of is checks on the function type, that won't work the compiled functions that way. Replacing some of those seems easy to do. This one is more tricky:

    @cached_property
    def is_descriptor(self):
        if self.is_boundmethod:
            return False
        is_descriptor = type(self.wrapped_object).__get__ \
            is not types.FunctionType.__get__  # noqa
        if six.PY2:
            is_descriptor = is_descriptor and \
                not (self.is_unboundmethod or self.is_boundmethod)
        return is_descriptor

I tried editing it a bunch, but it seems very odd in its expectations of what can be done to a function.
