Sebastian Poxhofer 00043d193e test(linters): add codeblock linter rule for spec fixtures (#44551)
* ci(linter): add renovate/codeblock-in-spec-fixtures rule

Add a custom oxlint rule that requires the codeBlock (or stripIndent)
template helper from common-tags for multi-line string fixtures in spec
files (enabled for **/*.spec.ts and test/** only).

The rule only flags shapes whose value can round-trip through the
common-tags helpers unchanged, since both codeBlock and stripIndent trim
the end result and strip the shortest line indentation:

- only literals spanning multiple source lines are flagged (escaped \n
  one-liners are left alone: tagging them is not value-preserving in
  general and gains nothing)
- values with leading/trailing whitespace (e.g. fixtures ending in a
  newline) are not flagged
- tagged templates, describe/it titles, and inline snapshot arguments
  are skipped

All 55 pre-existing violations (22 files) were fixed with a one-off
codemod that re-emits each fixture indented to the statement depth and
verifies value preservation by evaluating codeBlock on the rewritten
template (substitutions kept as opaque placeholders). One site
(pip_requirements/artifacts.spec.ts) mixes line continuations with
escaped newlines and was tagged verbatim instead of re-indented.

* ci(linter): address review findings

Make getSimpleRequirementsFile in pip-compile/extract.spec.ts
value-preserving again: tagging the whole template with codeBlock
trimmed the trailing blank line when deps is empty (the headerOnly.txt
case), silently changing the fixture from ending in '#\n\n' to '#'.
Tag only the static header and append the deps section via a
single-line template, which reproduces the original string exactly
for both empty and non-empty deps (verified by executing old vs new
in node).

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.
