Popular third party extension modules
To test C API changes in Python, it’s useful to test a bunch of popular
extension modules to check if they still build.
Cython
The first important candidate is Cython, many projects use it:
- Cython
- lxml
- numpy (Cython + C API)
- pandas
- pyzmq (for Jupyter)
- scipy
Python C API
Use directly the C API:
- Mercurial
- Pillow
- cffi
- psycopg2
