Welcome to the Cheese Shop: setuptools, virtualenv and PyPUG
- 1. Welcome to the Cheese Shop setuptools, virtualenv and PyPUG Dale Visser https://dalevisser.wordpress.com/
- 2. Outline ● Cheese Shop? ● Setuptools ● Sdists, Eggs and Wheels ● Demo of pip and virtualenv ● Online Resources ● Conclusion Image credit: http://www.clker.com/clipart-cheese-wheel.html
- 3. Cheese Shop? ● Name comes from Monty Python, of course. – For full history: https://youtu.be/pZTiAkwiPgI – For the sketch: https://youtu.be/B3KBuQHHKx0 ● Corporate sponsor preferred something more formal, less likely to infringe copyright: – The Python Package Index, or PyPI – https://pypi.python.org/pypi
- 6. Python Distributions – 2 kinds ● Source Distributions or “sdists” – python setup.py sdist ● Built Distributions (“bdists”) – Eggs ● python setup.py bdist or ● python setup.py bdist_egg – Wheels ● python setup.py bdist_wheel ● python setup.py bdist_wheel --universal
- 7. Egg and Wheel Distribution Formats ● Eggs - classic – .egg – zip archive or folder containing package and metadata – .egg-info – metadata folder that sits alongside installed package folder – Lacks formal specification, but is well-described: http://bit.ly/egg_format ● Wheels – pip and PyPI preferred – .whl – zip archive containing package and metadata – .dist-info – metadatafolder that sits alongside installed package folder – Relevant specifications: ● PEP-376 - Database of Installed Python Distributions ● PEP-426 - Metadata for Python Software Packages 2.0 ● PEP-427 - The Wheel Binary Package Format 1.0
- 8. Universal Wheels? ● Platform wheels – Contain compiled extensions – Specific to a platform ● Linux ● Windows ● OSX – PyPI only supports Windows and OSX ● Pure Python wheels – No compiled extensions – Subtype: universal wheels ● Support both Python 2 and 3
- 9. pip and virtualenv demo
- 10. Online Resources ● Your first, best resource is this: https://packaging.python.org/ – It is a collaborative resource created by the PyPI people. E.g., find out about twine ● Also, you can “pip install” from git repos!: http://bit.ly/pip_vcs Image credit: http://www.clker.com/clipart-9829.html
- 11. Conclusion ● This talk just scratched the surface. ● Keeping your library-dependent software secure: – Have a look at OWASP Dependency Check. – With any luck, a near-future release will be Python- aware.
