Sebastian Poxhofer a473e73b3e fix(linters): forbid inert counts in v8 coverage-ignore comments (#45287)
Adds a custom oxlint rule renovate/v8-ignore-no-count that flags the
count form '/* v8 ignore next <N> */'. The count is not honored by
vitest's ast-v8-to-istanbul hint parser, which captures only the
keyword (if/else/next/file); 'next' always exempts exactly the next
AST node. Trailing counts therefore suggest a line range that is never
applied and mislead readers.

The rule is autofixable (drops the count, preserving actual behavior)
and has been applied to all existing occurrences.

This datasource returns Python releases from the python.org API.

It also fetches deprecated versions from the Endoflife Date datasource.

Because Renovate depends on containerbase/python-prebuild it will also fetch releases from the GitHub API.

Example custom manager

Below is a custom regex manager to update the Python versions in a Dockerfile. Python versions sometimes drop the dot that separate the major and minor number: so 3.11 becomes 311. The example below handles this case.

ARG PYTHON_VERSION=311
FROM image-python${PYTHON_VERSION}-builder:1.0.0
{
  "customManagers": [
    {
      "customType": "regex",
      "managerFilePatterns": ["/^Dockerfile$/"],
      "matchStringsStrategy": "any",
      "matchStrings": [
        "ARG PYTHON_VERSION=\"?(?<currentValue>3(?<minor>\\d+))\"?\\s"
      ],
      "autoReplaceStringTemplate": "ARG PYTHON_VERSION={{{replace '\\.' '' newValue}}}\n",
      "currentValueTemplate": "3.{{{minor}}}",
      "datasourceTemplate": "python-version",
      "versioningTemplate": "python",
      "depNameTemplate": "python"
    }
  ]
