Bug report

As far as I can tell this line:

will raise a TypeError and should be a 2 argument form as seen earlier in the same method.

However, as eitherhash_based is False,source_hash has already been generated or the code returns early I don't think this line can be reached. (Maybe if you have a flaky version of get_data that sometimes raises an ImportError/EOFError??).

Example:

>>>_imp.source_hash(_RAW_MAGIC_NUMBER,b'')b's\x8d\x9c\xd5\xd5\xe8\x7fs'>>>_imp.source_hash(b'')Traceback (mostrecentcalllast):File"/opt/local/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/code.py",line90,inruncodeexec(code,self.locals)File"<input>",line1,in<module>TypeError:source_hash()missingrequiredargument'source' (pos2)

Edit: Sorry, as I opened the issue from within the source line via 'reference in new issue' I think I accidentally skipped the bug report format that would have given this a label.
