Sync .github from Master Workflow

Quick Reference

Item Value
Workflow file .github/workflows/sync-github-from-master.yml
Workflow name (Actions UI) Sync .github from master
Triggers Push to master (.github/**), weekly schedule, workflow_dispatch
Runner ubuntu-latest
Permissions contents: write, pull-requests: write

Overview

Opens pull requests that copy only the .github/ directory from master onto downstream release branches listed in syncGithubFromMasterTargets in branch-policy.json.

Typical targets: alpha, canary, gold, prerelease, V105-LTS, V85-LTS, V110.

Not a merge of master: the job checks out the target branch tip, then runs git checkout origin/master -- .github. That replaces the .github/ tree with the files from master at that moment. Downstream branches do not need to contain master in Git history.

Behaviour

  1. For each target branch, create or update sync/github-from-master-<target> from origin/<target>.
  2. Run git checkout origin/master -- .github (path copy from master, not git merge master).
  3. If there are changes, force-push the sync branch and open a PR (or skip if one is already open).
  4. Label chore:workflow-sync when the label exists.
