10. at least 49,9% of Python software packaged in Fedora supports

    Python 3

11. at least 49,9% of Python software packaged in Fedora supports

    Python 3 45,5% has the Py 3 version packaged

12. Help us port! 3 PYTHON3 PYTHON3 PYTHON http://fedora.portingdb.xyz

13. None

14. Fedora infra Desktop toolkits Big non-Python apps

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.

    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

19. %if 0%{?rhel} && 0%{?rhel} <= 6 %{!?__python2: %global \ __python2

    /usr/bin/python2} %{!?python2_sitelib: %global \ python2_sitelib %(%{__python2} -c %endif %if 0%{?fedora} > 12 || 0%{?rhel} > %global with_python3 1 %global __python3 python3 %endif

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!

32. I. Python 3 II. Automating Packaging III. System Python

33. System Python /usr/libexec/system-python An effort to minimize minimal installs (cloud

    images)

34. Python stdlib by disk size test asyncio email tkinter encodings

    distutils unittest pydoc_data ensurepip ctypes lib2to3 idlelib individual modules

35. System Python libs /usr/libexec/system-python /usr/lib/python3.5/ lib2to3 unittest venv ensurepip pydoc

    encodings sqlite3 collections logging distutils html test tkinter turtledemo idlelib system-python-libs python3-libs python3-test python3-tkinter python3 system-python /usr/bin/python3

36. Possible users: DNF, cloud-init

37. Possible users: DNF, cloud-init Future: Isolation of system tools?
