#appraisal_normalization_env ⇒ Object

Appraisal generation normally uses the release-normalized environment. During family templating it instead needs the caller's deliberately selected local graph so generated Appraisal Gemfiles can resolve unpublished sibling dependencies.

  env.reject do |name, _value|
    name == "K_JEM_TEMPLATING" || active_local_path_env?(name)
  end
end

#bundled_with_checksum_mismatch?(path) ⇒ Boolean

A release reset updates both BUNDLED WITH and CHECKSUMS. When a nested tool leaked its Bundler into a member lockfile, a later cleanup can otherwise replace only the checksum entry and leave an impossible lockfile behind. Only flag a mismatch when the lockfile already tracks Bundler in CHECKSUMS, preserving older lockfiles that lack that entry.

Returns:

  • (Boolean)
