# frozen_string_literal: true module Puma # Puma::Launcher uses StateFile to write a yaml file for use with Puma::ControlCLI. # # In previous versions of Puma, YAML was used to read/write the state file. # Since Puma is similar to Bundler/RubyGems in that it may load before one's app # does, minimizing the dependencies that may be shared with the app is desired. # # At present, it only works with numeric and string values. It is still a valid # yaml file, and the CI tests parse it with Psych. # class StateFile ALLOWED_FIELDS = %w!control_url control_auth_token pid running_from! # @deprecated 6.0.0 FIELDS = ALLOWED_FIELDS def initialize @options = {} end def save(path, permission = nil) contents = "---\n".dup @options.each do |k,v| next unless ALLOWED_FIELDS.include? k case v when Numeric contents << "#{k}: #{v}\n" when String next if v.strip.empty? contents << (k == 'running_from' || v.to_s.include?(' ') ?
