Jamie Tanna 28ed2ee25e fix(datasource/go): treat modules with go host rule credentials as private (#47031)
When determining whether a Go module is public - which infers whether to
cache it - we had previously miscategorised authenticated traffic to Go
module proxies, as we only looked for `GOPROXY`, `GONOPROXY` and
`GOPRIVATE`.

Instead, we should treat a package as private if there is an
authenticated Host Rule that matches the Go module.

We can do this by checking for `hostType: go`, to catch only Go module
specific authentication, and to avoid catching i.e. auth to
`github.com`.

If any credentials (`token`, `password` or `httpsPrivateKey`) are found,
we treat this as credentialed.

Datasources

Datasources are used in Renovate primarily to fetch released versions of packages.

Follow the class-based programming style

New datasources must follow the class-based programming style. Use the java-version datasource as a reference.

Add the datasource to the API in api.ts so that the new datasource is usable. If you find Unused HTTP mocks errors in the Vitest tests and your mocked URLs are correct, make sure the datasource is correctly registered.

getReleases

The minimum exported interface for a datasource is a function called getReleases that takes a lookup config as input.

The config has:

  • packageName: the package's full name including scope if present (e.g. @foo/bar)
  • registryUrls: an array of registry URLs to try

getReleases should return an object having:

  • releases: an array of strings of matched versions. This is the only mandatory field
  • deprecationMessage: a string description of the package's deprecation notice, if applicable
  • sourceUrl: a HTTP URL pointing to the source code (for example on GitHub)
  • homepage: a HTTP URL for the package's homepage. Ideally should be empty if the homepage and sourceUrl are the same
  • changelogUrl: a URL pointing to the package's changelog (could be a Markdown file, for example). If not present then Renovate will search the sourceUrl for a changelog file
  • tags: an object mapping tag → version, for example tags: { latest: '3.0.0' }. This is only used by the followTags function

getDigest

Datasources that support digests (like Docker digests and Git commit hashes) can export a getDigest function.

The getDigest function has two inputs:

  • config: the Renovate config for the package being updated, has the same fields as getReleases
  • newValue: the version or value to retrieve the digest for

The getDigest function returns a string output representing the digest value. If no digest is found, the getDigest function should return null.
