Robert Hensing ae5cb919f5 nixos/testing/nodes: Do allow aliases
Aliases exist for a reason. Sure it is nice to make sure that
some aliases aren't used within Nixpkgs, but this creates two problems
which are far worse than your failing to meet your neatness compulsions.

- Users encounter missing attributes, https://github.com/NixOS/nixpkgs/issues/264577
  wasting their time, stalling their progress, and even occupying others
  time that would be better spent on fixing *real* issues.

- Hydra doesn't treat evaluation errors seriously enough, with the
  effect that actual relevant test failures are masked by evaluation
  failures such as those caused by this no aliases business.

- We don't even have the infrastructure to get rid of aliases, because
  all warnings in package attributes are disallowed by Nixpkgs CI
  tooling, last I checked.

Before re-disabling this, make sure that

- An actually helpful deprecation process is in place.

- Aliases are still allowed when `nixos-lib.runTests` and
  `pkgs.testers.runNixOSTest` are invoked by external projects.
  For instance, `all-tests.nix` could provide such an
  override (e.g. with `newScope`).

NixOS

NixOS is a Linux distribution based on the purely functional package management system Nix. More information can be found at https://nixos.org/nixos and in the manual in doc/manual.

Testing changes

You can add new module to your NixOS configuration file (usually its /etc/nixos/configuration.nix). And do sudo nixos-rebuild test -I nixpkgs=<path to your local nixpkgs folder> --fast.

Reviewing contributions

When changing the bootloader installation process, extra care must be taken. Grub installations cannot be rolled back, hence changes may break peoples installations forever. For any non-trivial change to the bootloader please file a PR asking for review, especially from @edolstra.

Module updates

Module updates are submissions changing modules in some ways. These often contains changes to the options or introduce new options.

Reviewing process:

  • Ensure that the module maintainers are notified.
    • CODEOWNERS will make GitHub notify users based on the submitted changes, but it can happen that it misses some of the package maintainers.
  • Ensure that the module tests, if any, are succeeding.
  • Ensure that the introduced options are correct.
    • Type should be appropriate (string related types differs in their merging capabilities, loaOf and string types are deprecated).
    • Description, default and example should be provided.
  • Ensure that option changes are backward compatible.
    • mkRenamedOptionModuleWith provides a way to make option changes backward compatible.
  • Ensure that removed options are declared with mkRemovedOptionModule
  • Ensure that changes that are not backward compatible are mentioned in release notes.
  • Ensure that documentations affected by the change is updated.

Sample template for a module update review is provided below.

##### Reviewed points

- [ ] changes are backward compatible
- [ ] removed options are declared with `mkRemovedOptionModule`
- [ ] changes that are not backward compatible are documented in release notes
- [ ] module tests succeed on ARCHITECTURE
- [ ] options types are appropriate
- [ ] options description is set
- [ ] options example is provided
- [ ] documentation affected by the changes is updated

New modules

New modules submissions introduce a new module to NixOS.

Reviewing process:

  • Ensure that the module tests, if any, are succeeding.
  • Ensure that the introduced options are correct.
    • Type should be appropriate (string related types differs in their merging capabilities, loaOf and string types are deprecated).
    • Description, default and example should be provided.
  • Ensure that module meta field is present
    • Maintainers should be declared in meta.maintainers.
    • Module documentation should be declared with meta.doc.
  • Ensure that the module respect other modules functionality.
    • For example, enabling a module should not open firewall ports by default.

Sample template for a new module review is provided below.
