| # This workflow does double duty: it runs checks against PRs/pushes, and it | |
| # updates flake.lock (run from a schedule or manually). | |
| # | |
| # This approach seems simpler than having a separate lockfile-updating workflow | |
| # that creates a PR that gets the normal check workflow ran against it before | |
| # merging, especially since (according to | |
| # https://github.com/DeterminateSystems/update-flake-lock) GitHub Actions does | |
| # not run workflows against PRs created by a GitHub Action. | |

| # `git push` only works because branch protection is not enabled. | |
| # | |
| # Currently branch protection is not effective anyway, since the only | |
| # contributor (marienz) has admin permissions, and applying branch | |
| # protection to administrators seems to be an "organization" feature. | |
| # | |
| # The supported path seems to be "create a PR and use the API to merge | |
| # it", but that's more work to implement (see above): revisit later. | |
| # TODO: try to improve caching. | |
| # | |
| # We spend a lot of time fetching sources. Caching all of ~/.cache/nix/gitv3 is | |
| # not ideal: it is too large (3GiB) and we don't expire individual checkouts. | |
| # https://github.com/DeterminateSystems/magic-nix-cache/issues/28 may help. | |
