| # This action cannot be skipped altogether because it is a mandatory status check. | |
| # Instead we conditionally skip it at job level, instead of workflow level. | |
| on: | |
| # Execute on `push` and not `pull_request` because `pull_request` | |
| # always compares if the `paths` have changed compared to the PR base. | |
| # This is an issue because it means that all commits to the branch | |
| # will trigger the gemfile update process, which is unnecessary and expensive. | |
| # | |
| # By executing on `push`, GitHub compares `paths` with the parent commit, | |
| # meaning the gemfile update process will only execute on the exact commit | |
| # that changes any of the `paths`. | |
| # | |
| # Because this process is slow and expensive, and we commit the gemfile changes back | |
| # to the branch, we have an additional filter to only execute this action on branches | |
| # attached to a PR. | |
| # | |
| # We could do the inverse: execute this action on `pull_request`, and additionally check | |
| # if `paths` was changed compared to the parent commit, but this proved more complicated. | |
| push | |
| # Ensure obsolete job is cancelled if another commit is pushed to the same branch. | |
