DEV: enable frozen string literal on all files This reduces chances of errors where consumers of strings mutate inputs and reduces memory usage of the app. Test suite passes now, but there may be some stuff left, so we will run a few sites on a branch prior to merging 2019-05-03 06:17:27 +08:00			`# frozen_string_literal: true`

FIX: Revert Demon::DemonBase back to Demon::Base (#8132) I introduced DemonBase because I had got some conflict between `demon/base.rb` and `jobs/base.rb`, however, to not rename base class, it is possible to use regex on absolute path in Zeitwerk custom inflector. 2019-10-02 12:54:08 +08:00			`class ForkExecDemon < Demon::Base`
