source_to_code is used to load the code object which has a source path specified:
https://github.com/python/cpython/blob/0f5a28f834bdac2da8a04597dc0fc5b71e50da9d/Lib/py_compile.py#L144-L145 https://docs.python.org/3/library/importlib.html#importlib.abc.InspectLoader.source_to_code "The path argument should be the “path” to where the source code originated from, which can be an abstract concept (e.g. location in a zip file)." Seems to be the reason for adding a path to the .pyc file: https://docs.python.org/3/library/compileall.html#cmdoption-compileall-d "This will appear in compilation time tracebacks, and is also compiled in to the byte-code file, where it will be used in tracebacks and other messages in cases where the source file does not exist at the time the byte-code file is executed." The path specified in the second argument to source_to_code is included into the dump of a code object: python -m py_compile ./bdist_egg.py (Pdb) cfile './__pycache__/bdist_egg.cpython-38.pyc' (Pdb) dfile (Pdb) file './bdist_egg.py' # vs pip3 install -t ./ setuptools (Pdb) cfile '/tmp/pip-unpacked-wheel-79blnlyq/setuptools/command/__pycache__/bdist_egg.cpython-38.pyc' (Pdb) dfile (Pdb) file '/tmp/pip-unpacked-wheel-79blnlyq/setuptools/command/bdist_egg.py' (Pdb) '/tmp/pip-unpacked' in str(marshal.dumps(loader.source_to_code(source_bytes, dfile or file, _optimize=optimize))) True (Pdb) '/tmp/pip-unpacked' in str(marshal.dumps(loader.source_to_code(source_bytes, './setuptools/command/bdist_egg.py', _optimize=optimize))) False (Pdb) './setuptools/command/bdist_egg.py' in str(marshal.dumps(loader.source_to_code(source_bytes, './setuptools/command/bdist_egg.py', _optimize=optimize))) True The absolute paths are passed in from pip: https://github.com/pypa/pip/blob/20.0.2/src/pip/_vendor/distlib/util.py#L596 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1882535 Title: [focal/core20][python3.7+] staging conflicts when multiple python parts have the same python dependencies To manage notifications about this bug go to: https://bugs.launchpad.net/snapcraft/+bug/1882535/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
