Sequence#

  1. enable git signing

    git config commit.gpgsign true
    git config user.signingkey ${gpg_signing_key}
    
  2. setup a bare git repository serving static pages. Follow this blog post

  3. if you need to publish a package on AUR follow the instructions

  4. finish working on the development branch

    cd ${project_directory}
    
  5. check that the current branch is not master

    git branch --no-color --show-current
    # dev
    
  6. if you need to publish a new asciinema video follow the instructions

  7. commit

    git add -A
    git commit
    git push
    
  8. update version numbers

    • ./setup.cfg

    • ./docs/conf.py

    • ./packages/*

  9. if necessary update dependencies in

    • ./requirements.txt

    • ./requirements-dev.txt

    • ./setup.cfg

    and regenerate the pinned dependencies

    make regenerate-freeze
    

    Read the changelogs of the dependencies and decide what packages to update

  10. run a final test

    make uninstall-dev; make install-dev
    make doc
    make test
    make install
    cd ~ && python3 -c "import ${package_name}" && cd ${OLDPWD}
    make uninstall
    make clean
    
  11. For each of these files update copyright years, emails and contributors

    • ./README.md

    • ./docs/conf.py

    • ./docs/copyright_license.rst

    • all changed Python source files

    • ./packages/*

  12. commit

    git add -A
    make pre-commit
    git commit
    git push
    
  13. update the documentation

    make clean && make doc
    rm -rf ~/html && cp -aR docs/_build/html ~
    git branch --delete --force docs
    git checkout --orphan docs
    rm -rf .mypy_cache .venv
    git rm --cached -r .
    git clean -f && git clean -f -d
    mv ~/html/{*,.buildinfo} .
    git add -A
    git commit --no-verify -m "New release"
    git push --force deploy-docs docs
    
  14. merge the branches and tag the release

    git checkout master
    git merge ${dev_branch}
    
  15. tag the release.

    git tag -s -a ${version_id}
    

    Write a message like this. Use the infinitive tense

    Release ${MAJOR}.${MINOR}.${PATCH}
    
    - Item 1
    - Item 2
    - [ ... ]
    - Item n
    
  16. push the changes

    git push
    git push --tags
    
  17. upload the package to PyPI if applicable

    make install-dev
    make clean
    make dist
    make upload
    
  18. upload the package on the software page. Follow the instructions reported here

  19. update downstream distribution packages. See the updating packages section

  20. update other resources if applicable

Other steps#

Upstream packages#

AUR#

  • An alternative to GitHub Pages [3]

  1. create an Arch Linux virtual machine

  2. create a bare repository

    git init --bare ${project_directory}
    cd ${project_directory}
    
  3. use this post-receive git hook

  5. mark the hook as executable

    chmod 700 .git/hooks/post-receive
    
  6. add the pacman command to the ones not requiring password in the sudoers file

    visudo
    build-user ALL=NOPASSWD: /bin/pacman
    
  7. on the local repository (development machine) create a new remote called packages-aur which points to the Arch Linux virtual machine

  8. create a repository containing the AUR source. Add a normal origin remote and a git aur remote that to points to https://aur.archlinux.org/"$(basedir "${projects_aur_git_directory}")".git

Updating packages#

AUR#

git push --atomic packages-aur master ${MAJOR}.${MINOR}.${PATCH}
make clean
git branch -D packages-aur && git fetch --all && git checkout packages-aur
cp PKGBUILD .SRCINFO ${projects_aur_git_directory}
git checkout ${dev_branch}
cd ${projects_aur_git_directory}
git add PKGBUILD .SRCINFO
git commit -m "New release."
git push
git push aur

Asciinema#

  1. create a new asciinema demo file

    cd ./asciinema
    touch ${project_directory}_asciinema_${MAJOR}_${MINOR}_${PATCH}_demo.sh
    
  2. edit the demo file

  3. record and check the demo file

    . .venv/bin/activate
    asciinema rec --command=./${project_directory}_asciinema_${MAJOR}_${MINOR}_${PATCH}_demo.sh ${project_directory}_asciinema_${MAJOR}_${MINOR}_${PATCH}.json
    asciinema play ${project_directory}_asciinema_${MAJOR}_${MINOR}_${PATCH}.json
    deactivate
    
  4. upload

    asciinema upload ${project_directory}_asciinema_${MAJOR}_${MINOR}_${PATCH}.json
    deactivate
    
  5. edit the ./README.md file with the new asciinema link

  6. commit

    git add -A
    git commit
    git push
