Add a lot of runtime defaults to stubs with `stubdefaulter`

[sobolevn]

You can do the same with:

# Install
pip install stubdefaulter no_implicit_optional

# Run
PYTHONPATH='PATH_TO_YOUR/site-packages/django' stubdefaulter -p django-stubs
no_implicit_optional django-stubs --use-union-or

One question; can we add stubdefaulter to CI to keep defaults populated for new changes?

typeshed does this! I will add it in the next PR, so it won't be hidden among 3000 lines diff 😆

Sounds great!

I suppose one way is to check git for changes after running the command. Just want to drop off a run I've used for these cases a couple of times in other CI's:

        run: |
          set -e
          <install deps>
          git add -A
          <run command>
          if [ -n "$(git status --porcelain -- <path>)" ]; then
            echo "::error::Build result differs. Run '<run command>' then commit and push any changes"
            git status --porcelain -- <path>
            exit 1
          fi

Note: replace <> marked parts with stuff for stubdefaulter

@flaeppe I have a better idea :)

Yeah that's even better
