From 5d5c0f4f4358f4349d9e2db59cf90b1f5de24e81 Mon Sep 17 00:00:00 2001 From: ThibG Date: Tue, 7 Nov 2017 19:08:14 +0100 Subject: Twidere mention workaround (#5552) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Work around Twidere and Tootdon bug Tootdon and Twidere construct @user@domain handles from mentions in toots based solely on the mention text and account URI's domain without performing any webfinger call or retrieving account info from the Mastodon server. As a result, when a remote user has WEB_DOMAIN ≠ LOCAL_DOMAIN, Twidere and Tootdon will construct the mention as @user@WEB_DOMAIN. Now, this will usually resolve to the correct account (since the recommended configuration is to have WEB_DOMAIN perform webfinger redirections to LOCAL_DOMAIN) when processing mentions, but won't do so when displaying them (as it does not go through the whole account resolution at that time). This change rewrites mentions to the resolved account, so that displaying the mentions will work. * Use lookbehind instead of non-capturing group in MENTION_RE Indeed, substitutions with the previous regexp would erroneously eat any preceding whitespace, which would lead to concatenated mentions in the previous commit. Note that users will “lose” up to one character space per mention for their toots, as that regexp is also used to remove the domain-part of mentioned users for character counting purposes, and it also erroneously removed the preceding character if it was a space. --- app/javascript/mastodon/features/compose/util/counter.js | 2 +- app/models/account.rb | 2 +- app/services/process_mentions_service.rb | 9 ++++++--- 3 files changed, 8 insertions(+), 5 deletions(-) (limited to 'app') diff --git a/app/javascript/mastodon/features/compose/util/counter.js b/app/javascript/mastodon/features/compose/util/counter.js index e6d2487c5..700ba2163 100644 --- a/app/javascript/mastodon/features/compose/util/counter.js +++ b/app/javascript/mastodon/features/compose/util/counter.js @@ -5,5 +5,5 @@ const urlPlaceholder = 'xxxxxxxxxxxxxxxxxxxxxxx'; export function countableText(inputText) { return inputText .replace(urlRegex, urlPlaceholder) - .replace(/(?:^|[^\/\w])@(([a-z0-9_]+)@[a-z0-9\.\-]+[a-z0-9]+)/ig, '@$2'); + .replace(/(^|[^\/\w])@(([a-z0-9_]+)@[a-z0-9\.\-]+[a-z0-9]+)/ig, '$1@$3'); }; diff --git a/app/models/account.rb b/app/models/account.rb index 1142e7c79..7e4d29f96 100644 --- a/app/models/account.rb +++ b/app/models/account.rb @@ -45,7 +45,7 @@ # class Account < ApplicationRecord - MENTION_RE = /(?:^|[^\/[:word:]])@(([a-z0-9_]+)(?:@[a-z0-9\.\-]+[a-z0-9]+)?)/i + MENTION_RE = /(?<=^|[^\/[:word:]])@(([a-z0-9_]+)(?:@[a-z0-9\.\-]+[a-z0-9]+)?)/i include AccountAvatar include AccountFinderConcern diff --git a/app/services/process_mentions_service.rb b/app/services/process_mentions_service.rb index aa649652c..65e6b1361 100644 --- a/app/services/process_mentions_service.rb +++ b/app/services/process_mentions_service.rb @@ -10,18 +10,21 @@ class ProcessMentionsService < BaseService def call(status) return unless status.local? - status.text.scan(Account::MENTION_RE).each do |match| + status.text = status.text.gsub(Account::MENTION_RE) do |match| begin - mentioned_account = resolve_remote_account_service.call(match.first.to_s) + mentioned_account = resolve_remote_account_service.call($1) rescue Goldfinger::Error, HTTP::Error mentioned_account = nil end - next if mentioned_account.nil? || (mentioned_account.ostatus? && status.stream_entry.hidden?) + next match if mentioned_account.nil? || (mentioned_account.ostatus? && status.stream_entry.hidden?) mentioned_account.mentions.where(status: status).first_or_create(status: status) + "@#{mentioned_account.acct}" end + status.save! + status.mentions.includes(:account).each do |mention| create_notification(status, mention) end -- cgit
