Dependabot bundler

Bundler will gather all PRs which were created by app/dependabot user. Then, it will apply go get -u using the modules in the prs that it found. It will do that instead of using git magic to combine the prs to avoid the following problems:

• merge conflicts
• dependencies getting out of sync ( something updating to x while the next downgrades it to y or vica-versa )
• dependency chain conflicts

Once all updates have been applied, it will create a single commit and a PR.

It doesn't attempt to merge PRs causing various merge conflicts. It will basically just do what dependabot would do but apply it separately as a composite update.

Bundler only ever commits go.mod and go.sum files. It never stages any other changes.

Example running every Friday:

name: Dependabot Bundler

on:
  schedule:
    - 0 0 * * 5 # every Friday at 00:00

jobs:
  bundler:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v2
      - name: Setup Go
        uses: actions/setup-go@v2
        with:
          go-version: 1.18.x
      - name: Cache go-build and mod
        uses: actions/cache@v2
        with:
          path: |
            ~/.cache/go-build/
            ~/go/pkg/mod/
          key: go-${{ hashFiles('go.sum') }}
          restore-keys: |
            go-          
      - name: Install Dependabot Bundler
        run: |
          go install github.com/Skarlso/dependabot-bundler@v0.0.3
      - name: Run Dependabot Bundler
        run: |
          dependabot-bundler --token ${{ secrets.GITHUB_TOKEN }} --repo test --owner Skarlso

If everything goes well, it should result in a PR like this:

This is an actual PR located here which was created with dependabot-bundler and merged.

Dependabot can apply labels to the created PR such as:

      - name: Run Dependabot Bundler
        run: |
          dependabot-bundler --token ${{ secrets.GITHUB_TOKEN }} --repo test --owner Skarlso --labels bug,duplicate

Which will result in a PR like this:
