fix: Error when installing using pip - #7
webbrain-one wants to merge 1 commit into
Conversation
The source distribution was missing the Eigen library headers, causing compilation to fail when installing via pip. Update setup.py to properly include the Eigen directory in the package manifest. Closes bab2min#6

- Around line 4-5: Move the import statement that provides os above the here
assignment so os.path.abspath can execute successfully; keep the existing import
set and path computation unchanged.
- Around line 15-18: Update setup.py to import os before the here
initialization, initialize temp_tar to None, and move the urllib.request.urlopen
download and copyfileobj operations inside the existing try/finally. Pass a
finite timeout to urlopen, and have finally remove the temporary archive only
when temp_tar exists.
- Around line 11-12: Add the Eigen header files required by setup.py’s eigen_dir
check, including include/Eigen/Eigen/Dense, to the source distribution via
MANIFEST.in or by vendoring them in the repository. Ensure generated sdists
contain the headers for offline builds.
- Around line 13-20: Update setup.py to import os before resolving here, pin the
Eigen archive to an immutable source and verify its trusted SHA-256 before
extraction, and replace direct tar.extractall in the Eigen download flow with
validation of every member path and symlink/hardlink target to prevent
extraction outside here while remaining compatible with Python 3.5–3.8.

Add Eigen headers to the source distribution.
MANIFEST.in has no rule for include/Eigen, and the repository contains no Eigen headers. The generated sdist will omit include/Eigen/Eigen/Dense, so offline builds will fail. Add a manifest rule or vendor the headers.

Import os before resolving here, then secure Eigen extraction.
The build currently fails with NameError because setup.py uses os before importing it.
The workflows support Python 3.5–3.8, so validate member paths and link targets manually before extractall. Also pin Eigen to immutable content and verify a trusted SHA-256 before extraction.

Fix setup initialization and bound the Eigen download.
setup.py references os before importing it, so every build fails with NameError. Import os before here = ....
Then pass a finite timeout to urllib.request.urlopen. Move the download into the try/finally, initialize temp_tar = None, and remove the temporary archive when it exists. A copyfileobj failure currently leaves the archive behind.
