These workflows had no concurrency group, so every new push to a pull request left the older run going. This adds one: a new push to a PR cancels the older run for that PR, while pushes to branches and manual or scheduled runs are never cancelled.

Summary by CodeRabbit

  • Chores
    • Code analysis runs are now grouped by event type and reference, with in-progress runs canceled only for pull requests.

Walkthrough

The CodeQL workflow now groups runs by event type. It cancels in-progress runs for pull-request events, but not for pushes.

Changes: CodeQL workflow concurrency

The workflow groups runs by workflow and pull-request number, push ref, or run ID. It cancels in-progress runs only for pull-request events.

Merge Risk: Low · up to 109fa

Branch-push workflow runs may be skipped while waiting for an earlier run, so the concurrency key should be unique for non-pull-request events.

Minor · Stability & Availability · Quick win

Use a unique group for non-pull-request events.

Multiple pushes to the same branch share this group. With cancel-in-progress: false, GitHub still cancels an older pending run when a newer run enters the group. Only the in-progress run is preserved. This violates the requirement that branch pushes are not cancelled. Use github.run_id for non-pull-request events. (raw.githubusercontent.com)
