`nix-update` is unable to detect that the hashes are in `packages.nix`
and `lts.nix` instead of `generic.nix` (where the `.src` attribute lies)
respectively.
`nix-update` provides a `--override-filename` flag to override that
heuristic, so we use that.
Additionally, scope `lts.nix` to the 7.x version series by using
`--version-regex`.
We cannot rely on `buildGoModule`'s default test selection if
`subPackages` is set:
~~~
Running phase: checkPhase
? code.gitea.io/gitea [no test files]
? code.gitea.io/gitea/contrib/environment-to-ini [no test files]
checkPhase completed in 53 seconds
~~~
So we override it in `preCheck` and skip some tests that fail in our
sandbox (e.g. because they require networking).
Note that this does slow down building the package quite a bit because
there are a lot of tests to run.
Still worth it IMHO.
This slipped through the 1.21.11-1 -> 7.0.0 bump in
6c359d6488.
Upstream made this a noop with a deprecation warning instead of a
hard fail in https://codeberg.org/forgejo/forgejo/pulls/2864.
Note: In that PR (it's commit) they link to nixpkgs as downstream
consumer of it (`build/merge-forgejo-locales.go`).
