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`

DEV: Upgrading Discourse to Zeitwerk (#8098) Zeitwerk simplifies working with dependencies in dev and makes it easier reloading class chains. We no longer need to use Rails "require_dependency" anywhere and instead can just use standard Ruby patterns to require files. This is a far reaching change and we expect some followups here. 2019-10-02 12:01:53 +08:00			`class StrippedLengthValidator < ActiveModel::EachValidator`
