15. I. Python 3 II. Automating Packaging
16. A packager should: 1. Make sure SW plays nice 2. Integrate with rest of system 3. Check licenses, patents, etc.
17. A packager should: 1. Make sure SW plays nice 2. Integrate with rest of system 3. Check licenses, patents, etc. 4. Read 50 pages of guidelines 5. Know a weird macro language
18. %global pypi_name mypkg Name: python -%{pypi_name} Version: 2.4.25.1 Release: 1%{?dist} License: Python URL: https://github.com /%{pypi_name}/%{pypi_name} Source0: https://pypi.python .org/packages/source/p/%{ pypi_name}/%{pypi_name}-%{version }.tar.gz

20. from distutils.core import setup setup( name='mypkg ', version='2.4.25.1', author='Me', url='github.com/me/mypkg/', packages=['mypkg '], install_requires=['six '], )
21. Enter pyp2rpm # dnf install /usr/bin/pyp2rpm $ pyp2rpm mypkg
22. Enter pyp2rpm # dnf install /usr/bin/pyp2rpm $ pyp2rpm mypkg It might actually work!
23. We can use pyp2rpm to... Auto-build all of PyPI in COPR!
24. We can use pyp2rpm to... Auto-build all of PyPI in COPR! Why?
25. We can use pyp2rpm to... Auto-build all of PyPI in COPR! Why? - Test pyp2rpm
26. We can use pyp2rpm to... Auto-build all of PyPI in COPR! Why? - Test pyp2rpm - Run upstream tests
27. We can use pyp2rpm to... Auto-build all of PyPI in COPR! Why? - Test pyp2rpm - Run upstream tests - Provide a repository
28. dnf pip install -r requirements.txt (hypothetical command)
29. “PyPI” name Fedora pkg pyopencl python3-pyopencl mypy-lang python3-mypy
30. “PyPI” name Fedora pkg pyopencl python3-pyopencl mypy-lang python3-mypy $ dnf repoquery --provides python3 -pyopencl ... python3.5dist(pyopencl) = 2015.2 ...
31. “PyPI” name Fedora pkg pyopencl python3-pyopencl mypy-lang python3-mypy $ dnf repoquery --provides python3 -pyopencl ... python3.5dist(pyopencl) = 2015.2 ... Live in Fedora 25!
