New submission from Travis Lazar :
When running pyperformance html5lib test, the application crashes with
"ImportError: cannot import name 'Mapping' from 'collections'
(/py3buildpath/lib/python3.9/collections/__init__.py)"
To reproduce:
1 - Build Python from source. I produced with git commit
befa032d8869e0fab4732d910f3887642879d644 from cpython GitHub.
2 - Run pyperformance with: /py3buildpath/bin/pyperformance run
--python=/py3buildpath/bin/python3 --venv venvpath -b html5lib -o output.json
3 - Immediate crash is seen with message:
#!/bin/sh
