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 all the errors to get our tests green on Rails 5.1. 2017-08-31 12:06:56 +08:00			`class AddDirectoryItemsIndexes < ActiveRecord::Migration[4.2]`
FIX: add_directory_items_indexes causes migration to timeout on large databases, so create indexes concurrently 2016-10-26 03:30:21 +08:00			`disable_ddl_transaction!`

PERF: Remove ordering by username. * Ordering by username results in a very expensive query for very little upside UX wise. 2016-10-15 01:13:58 +08:00			`def change`
