![]() It does not make as much sense for an application like Inkscape, one that is designed to be open for use with third-party extensions and other types of modifications. This is ideal for a "closed" application that is not extensible. The key item that the example extension demonstrates is Library Validation, part of the macOS security stack, which ensures that libraries called by a piece of signed software are not altered.īy default, applications cannot run arbitrary code (plugins/extensions) that are not signed with the same team id or signed by Apple. (Note that running on a different architecture or Python version will cause a ModuleNotFoundError traceback Discussion: Library Validation The extension should run, returning a fixed stub of SVG contents.įor reference, python3 example.py > out.svg works on the CLI, on a Mac running Python 3.8. Key takeaway 2: ➡ Python is also unable to load a module signed by a different team than Inkscape. ImportError: code signature in (./example_dependencies/) not valid for use in process using Library Validation: mapping process and mapped file (non-platform) have different Team IDs (This example extension - built to demonstrate the issue as succinctly as possible - includes only a cpython-38-darwin.so and thus is is Mac and Python 3.8 specific.)Ĭall the extension from Extensions>Python Example., and observe that there is a traceback, ending in: Install the attached extension, python_example_unsigned.zip as one would for any extension on a Mac. This example extension does nothing other than import a library ( pyclipper, an open source vector graphics library available on PyPi) and return an SVG stub. We have built an example extension to demonstrate the issue. Steps to reproduce: Demonstration with unsigned third-party library This should be corrected by setting additional entitlements for the bundled Python, ideally matching that for "system" installed python. so files or other library objects can be called by extensions. Only "pure" Python code that does not include.
