Platform Python Stack: Roamap

There should be a copr repo where this all happens. In order to have permission, it has been created in the python-sig group: https://copr.fedorainfracloud.org/coprs/g/python/platform-python-stack/

create the platform-python package
- by cstratak
- stdlib and site-packages installs to /usr/lib(64)/platform-python3.6
  - done
- /usr/libexec/platform-python
  - done
- python3-config to platform-python-config, make it work
  - excluded the python-config binaries for now
- libpython.so to libplatform-python.so, make it work
  - done
- probably drop tkinter and tools until proven needed
  - stalled, it can be done later
- Make Platform-Python build without bootstrapping:
  - drop dependency on setuptools, pip, wheel
  - undo de-bundling of setuptools and pip, but delete the bundled pip wheel, making Python crash when -m venv is invoked
    - pip wheel is removed, setuptools is there
    - LATER make it not crash, but report a decent error message such as "Creating virtual environment with platform-python is not supported and is disabled. Use python3 instead."
- Enable the test suite
  - Two test case failures so far
    - One related to systemd-nspawn and the other to sysconfig, both can be safely skipped
- Enable profile guided optimizations and link time optimizations
  - Done
- /usr/libexec/platform-python3.X
  - Done

create macros from the example specfile
- by torsava
- done
- put them to python-rpm-macros
- https://github.com/torsava/python-rpm-macros/tree/private-torsava-master

adjust the python(abi) requires/provides mechanism
- by churchyard / mhroncok
- done
- patch at https://github.com/hroncok/rpm/commits/platform-python
- it should require/provide platform-python(abi) for stuff in /usr/lib(64)/platform-python
- the code lives in the rpm package: https://github.com/rpm-software-management/rpm/blob/master/scripts/pythondeps.sh
- this is part of python-rpm-generators package!
- LATER make python-rpm-generators run on platform python MAYBE?

adjust pybytecompile script
- should bytecompile stuff in /usr/lib/platform-python3.X with /usr/libexec/platform-python3.X
- by churchyard / mhroncok
- done
- patch at https://github.com/hroncok/rpm/commits/platform-python

start adding platform-python subpackages up until dnf
- done
- add bcond conditionals for all 3 subpackages: %bcond_without python2, python3, platform_python
- if present, remove the system python abi macro and/or shabeng adjusting for system-python
- check if the platform-python(abi) works

adjust dnf
- make /usr/bin/dnf use /usr/libexec/platform-python, make it require platform-python-dnf instead of python3-dnf
- done

grep the specfiles for system-python abi macro and or shebang requirement and remove it
- http://pkgs.fedoraproject.org/repo/rpm-specs-latest.tar.xz
- there are packages not covered by previous steps but using it
- by churchyard / mhroncok
- done

cleanup
- remove '/usr/lib64/python36.zip' from platform-python's sys.path
- Revisit bundled setuptools

Bootstrap order for Fedora

As we build stuff in copr, record it here so we know how to build it in Fedora:
