From 9b6a5ed109e1986149c1f15a41d4f442ae8ae39c Mon Sep 17 00:00:00 2001 From: ThibG Date: Mon, 19 Aug 2019 11:35:48 +0200 Subject: [PATCH] Add public blocks to /about/blocks (#11298) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Add automatic blocklist display in /about/blocks Inspired by https://github.com/Gargron/mastodon.social-misc * Add admin option to set who can see instance blocks * Normalize locales files * Rename “Sandbox” to “Silence” for consistency * Disable /about/blocks when in whitelist mode * Optionally display rationale for domain blocks * Only display domain blocks that have user-facing limitations, and order them * Redesign table of blocked domains to better handle long domain names and rationales * Change domain blocks ordering now that rationales aren't displayed right away * Only show explanation for block severities actually in use * Reword instance block explanations and add disclaimer for public fetch mode --- app/controllers/about_controller.rb | 34 ++++++++++- app/javascript/packs/public.js | 9 +++ app/javascript/styles/mastodon/tables.scss | 67 ++++++++++++++++++++++ app/models/domain_block.rb | 1 + app/models/form/admin_settings.rb | 4 ++ app/views/about/blocks.html.haml | 48 ++++++++++++++++ app/views/admin/settings/edit.html.haml | 6 ++ config/locales/en.yml | 24 ++++++++ config/routes.rb | 7 ++- config/settings.yml | 2 + 10 files changed, 197 insertions(+), 5 deletions(-) create mode 100644 app/views/about/blocks.html.haml diff --git a/app/controllers/about_controller.rb b/app/controllers/about_controller.rb index d276e8fe5..5e942e5c0 100644 --- a/app/controllers/about_controller.rb +++ b/app/controllers/about_controller.rb @@ -3,10 +3,12 @@ class AboutController < ApplicationController layout 'public' - before_action :require_open_federation!, only: [:show, :more] + before_action :require_open_federation!, only: [:show, :more, :blocks] + before_action :check_blocklist_enabled, only: [:blocks] + before_action :authenticate_user!, only: [:blocks], if: :blocklist_account_required?
