autopep8 incorrectly skips sources as standard library files

[nputikhin]

Symptoms: Trying to format a source with autopep8 v2023.6.0 doesn't do anything. The code is on a Debian-based system.

Output>autopep8:

Likely culprit is #103 - _site_paths were changed to include paths from sysconfig

vscode-autopep8/bundled/tool/lsp_utils.py

Lines 32 to 39 in 96c1d85

	_site_paths = set(
	str(pathlib.Path(p).resolve())
	for p in (
	as_list(site.getsitepackages())
	+ as_list(site.getusersitepackages())
	+ list(sysconfig.get_paths().values())
	)
	)

These paths are then used as prefixes to detect standard library files.

vscode-autopep8/bundled/tool/lsp_utils.py

Lines 57 to 60 in 96c1d85

	def is_stdlib_file(file_path: str) -> bool:
	"""Return True if the file belongs to the standard library."""
	normalized_path = str(pathlib.Path(file_path).resolve())
	return any(normalized_path.startswith(path) for path in _site_paths)

These files are skipped here:

vscode-autopep8/bundled/tool/lsp_server.py

Lines 349 to 351 in 96c1d85

	if utils.is_stdlib_file(document.path):
	log_warning(f"Skipping standard library file: {document.path}")
	return None

Output from python:

Python 3.11.4 (main, Jun  7 2023, 10:13:09) [GCC 12.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import sysconfig
>>> sysconfig.get_default_scheme()
'posix_local'
>>> sysconfig.get_paths()
{'stdlib': '/usr/lib/python3.11', 'platstdlib': '/usr/lib/python3.11', 'purelib': '/usr/local/lib/python3.11/dist-packages', 'platlib': 
'/usr/local/lib/python3.11/dist-packages', 'include': '/usr/include/python3.11', 'platinclude': '/usr/include/python3.11', 'scripts': 
'/usr/local/bin', 'data': '/usr/local'} 

'data' : '/usr/local' is a directory for data files (doc), but here it is also a base folder for the user's home folder. So the source file, which in our example is /usr/local/home/username/code/foo.py, gets skipped. I believe data shouldn't be added to _site_paths.

Can you try build 2023.7.11941910 and let me know if it works?

Just checked, can confirm that it works now. Thanks for fixing it so quickly!
