Consider that Resource.parent can be None when removing resources from the codebase #84
Description
scancode version: 4b57a7fe86
commoncode version: 32.2.1
python version: 3.13
os: linux
The problematic code:
commoncode/src/commoncode/resource.py
Lines 908 to 918 in aba7c1b
parent can be None:
commoncode/src/commoncode/resource.py
Lines 791 to 792 in aba7c1b
None has no children_names , it fails. This happens in example if the plugin_ignore of scancode trys to remove some resources from the codebase at: scancode/plugin_ignore.py(121)process_codebase()
How to reproduce:
❯ scancode --processes 10 -l -p -c -i --ignore "*/test/*" --license-score 20 --strip-root --json-pp test.json repos/git/github/systemd/systemd-stable
