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 18:17:27 -04:00			`# frozen_string_literal: true`

added setting to flush redis if you feel like doing so in dev 2013-05-02 19:55:56 -04:00			`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 08:33:20 -04:00			`puts "Flushing redis (development mode)"`
Revert "Revert "Merge branch 'master' of https://github.com/discourse/discourse"" This reverts commit 20780a1eeed56b321daf18ee6bbfe681a51d1bf4. * SECURITY: re-adds accidentally reverted commit: 03d26cd6: ensure embed_url contains valid http(s) uri * when the merge commit e62a85cf was reverted, git chose the 2660c2e2 parent to land on instead of the 03d26cd6 parent (which contains security fixes) 2020-05-23 00:56:13 -04:00			`Discourse.redis.flushdb`

DEV: Disable Redis warnings. 2020-06-16 00:53:04 -04:00
FIX: Redis may not be availiable on Redis initializer (#15955) 2022-02-15 10:25:22 -05:00			`begin`
			`if Gem::Version.new(Discourse.redis.info['redis_version']) < Gem::Version.new("6.2.0")`
			`STDERR.puts "Discourse requires Redis 6.2.0 or up"`
			`exit 1`
			`end`
			`rescue Redis::CannotConnectError`
			`STDERR.puts "Couldn't connect to Redis"`
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 08:36:07 -05:00			`end`
