This fixes labeling in the context of the `pull_request` trigger. Of course, this was supposed to immediately label rebuilds after eval finishes, but we somehow lost this along the way. Rebuilds are still labeled fairly soon, because the scheduled trigger will pick up the same PR within 10 minutes again and then apply the rebuild labels. But of course, immediate is better. The reason this happened is, that we're looking at `item.pull_request` only. This is the correct distinction between "issue items" and "pull request items", which we both get back from the /issues endpoint. But the payload for the `pull_request*` event doesn't contain this, so labeling in this case was treated like an issue and skipped the whole pull request part.
CI support files
This directory contains files to support CI, such as GitHub Actions and Ofborg.
This is in contrast with maintainers/scripts which is for human use instead.
Pinned Nixpkgs
CI may need certain packages from Nixpkgs.
In order to ensure that the needed packages are generally available without building, pinned.json contains a pinned Nixpkgs version tested by Hydra.
Run update-pinned.sh to update it.
ci/nixpkgs-vet.sh BASE_BRANCH [REPOSITORY]
Runs the nixpkgs-vet tool on the HEAD commit, closely matching what CI does.
This can't do exactly the same as CI, because CI needs to rely on GitHub's server-side Git history to compute the mergeability of PRs before the check can be started.
In turn, when contributors are running this tool locally, we don't want to have to push commits to test them, and we can also rely on the local Git history to do the mergeability check.
Arguments:
BASE_BRANCH: The base branch to use, e.g. master or release-24.05REPOSITORY: The repository from which to fetch the base branch. Defaults to https://github.com/NixOS/nixpkgs.git.
Branch classification
For the purposes of CI, branches in the NixOS/nixpkgs repository are classified as follows:
- Channel branches
nixos-ornixpkgs-prefix- Are only updated from
masterorrelease-branches, when hydra passes. - Otherwise not worked on, Pull Requests are not allowed.
- Long-lived, no deletion, no force push.
- Primary development branches
release-prefix andmaster- Pull Requests required.
- Long-lived, no deletion, no force push.
- Secondary development branches
staging-prefix,haskell-updatesandpython-updates- Pull Requests normally required, except when merging development branches into each other.
- Long-lived, no deletion, no force push.
- Work-In-Progress branches
backport-,revert-andwip-prefixes.- Deprecated: All other branches, not matched by channel/development.
- Pull Requests are optional.
- Short-lived, force push allowed, deleted after merge.
Some branches also have a version component, which is either unstable or YY.MM.
ci/supportedBranches.js is a script imported by CI to classify the base and head branches of a Pull Request.
This classification will then be used to skip certain jobs.
This script can also be run locally to print basic test cases.
