class Capsium::Reactor::PackageSaver

Folds a mounted package’s base plus its overlay into a NEW versioned .cap (name-version+patch.cap) in the reactor workdir: overlay content files replace, tombstones delete, dataset mutation logs replay into the dataset files (JSON/YAML per the source extension). Manifest, routes and security.json are regenerated, so the saved package passes ‘capsium package validate`.

Public Instance Methods

save (workdir)

(String workdir) → Hash[String, String]

Source

# File lib/capsium/reactor/package_saver.rb, line 25
def save(workdir)
  staging_parent = File.join(workdir, "saved")
  FileUtils.mkdir_p(staging_parent)
  stage = Dir.mktmpdir("fold-", staging_parent)
  begin
    fold_into(stage)
    output = Packager.new.pack(Package.new(stage), { force: true })
    { "path" => output,
      "sha256" => Digest::SHA256.file(output).hexdigest,
      "name" => @package.name,
      "version" => bumped_version }
  ensure
    FileUtils.remove_entry(stage)
  end
end

Returns {path, sha256, name, version} of the saved .cap.
