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 2019-05-02 17:17:27 -05:00			`# frozen_string_literal: true`

DEV: Apply syntax_tree formatting to `config/*` 2023-01-07 05:59:28 -06:00			`if Rails.env.development? && ENV["DISCOURSE_FLUSH_REDIS"]`
added basic passenger support, no long polling but functions clean up initializers so they are ordered properly 2013-03-11 07:33:20 -05:00			`puts "Flushing redis (development mode)"`

PERF: Use Redis `SET EX GET` instead of LUA script for counting (#15939) This will prevent Discourse from booting on Redis < 6.2.0 2022-02-15 07:36:07 -06:00			`end`
