Summary

Pin every remaining omitted setup-bun version in current workflows to the repository's existing Bun 1.3.14 standard, removing the same GitHub tag-resolution dependency that produced the recent HTTP 403 failures.

This deliberately preserves workflows that already make an explicit different choice:

  • Iroh/Miniflare's documented Bun 1.4.2 requirement;
  • existing 1.3.6 guard/app-host pins;
  • the explicit latest e2e canary.

Adds a repository-wide regression to tests/test_ci_change_areas.py requiring every oven-sh/setup-bun workflow step to declare a bun-version, so future omissions fail CI.

Scope

13 newly pinned setup steps across 10 workflows:

  • cloud VM migrate (3)
  • presence (2)
  • cloud VM env audit
  • cloud VM smoke
  • tmux corpus
  • release
  • macOS compatibility CI
  • nightly
  • activation benchmark
  • reload build

No project commands or dependency locks change.

Summary by cubic

Pins Bun 1.3.14 in 13 setup-bun steps across 10 workflows that previously resolved the oven-sh/setup-bun version from the GitHub tag, removing the tag-resolution dependency that caused HTTP 403 failures. Adds a regression test requiring every setup-bun step to declare an explicit bun-version. Workflows already pinning a different version are untouched.

Written for commit 71238d1. Summary will update on new commits.

📝 Walkthrough

Walkthrough

CI workflows now pin Bun to version 1.3.14. A repository-wide test checks that every oven-sh/setup-bun step declares a Bun version.

Change: Bug fix

Merge Risk: 🟡 Moderate · up to 71238

The workflows are currently pinned, but the new safeguard can miss a future removal of a Setup Bun version declaration. Bound the assertion to each step before merging.

Bound the version check to the current Setup Bun step.

The six-line slice can include the next workflow step. A later bun-version: line or comment can therefore satisfy the assertion after the current version is removed. Stop at the next step item and require the key within the current with: mapping.
