Python packaging

Package: python-bootstrap-evil

Major release

Arch's Python modules store the version number in the module path meaning they won't be picked up by a new Python release for example 3.11 => 3.12.

  • bump Python and rebuild it in a separate branch
  • bootstrap
  • find incompatible packages upfront?

Rebuild order

The python package repo has a script called genrebuild this should include all packages required for the rebuild:

Figuring out the order:

./genrebuild > rebuild-list.txt
cat rebuild-list.txt | xargs expac -Sv %n | sort | uniq > final.txt

For some reason our files.db include old packages which are no longer in the repos, arch-rebuild-order hard fails on missing packages so we clean those out with an ugly expac hack.

We can use arch-rebuild-order, it does not handle cyclic depenendencies but should be good enough (tm):

arch-rebuild-order --no-reverse-depends $(cat ./final.txt)

Python bootstrapping

Custom repository:

https://pkgbuild.com/~jelle/python3.11

cp /usr/share/devtools/pacman-staging.conf /usr/share/devtools/pacman-python.conf

Edit the config file and add above [staging]

[python]
SigLevel = Optional
Server = https://pkgbuild.com/~jelle/python3.11

sudo ln -s /usr/bin/archbuild /usr/bin/python-x86_64-build

repo-add python.db.tar.gz *.pkg.tar.zst

sudo python-x86_64-build --  -- --nocheck

Bootstrappping

  1. First build python-bootstrap (from svn-packages) with Python 3.X
  2. Yeet the packages into a pacman repository
  3. Build flit-core with bootstrapped build and installer
  4. Build python-installer comment out the sphinx build and repo-add it
  5. Build python-packaging (requires build,installer,flit-core). HACK: PYTHONPATH=src python -m build -nw required by python-build!
  6. Build python-build comment out the sphinx build and repo-add it
  7. Build python-pyproject-hooks and repo-add it
  8. build python-jaraco.text (requirement for bootstrap build of setuptools)
  9. build python-setuptools => bootstrap python-jaraco.text and tons more...
  10. Or build python-setuptools with export PYTHONPATH=/usr/lib/python3.10/site-packages/
  11. Wheel needs jaraco.functools and shit..
