From 2c51bc0ca5a4c3a4bb140b4b40dabdda859ebb94 Mon Sep 17 00:00:00 2001 From: unarist Date: Mon, 2 Apr 2018 21:51:02 +0900 Subject: [PATCH] Add missing rejection handling for Promises (#7008) * Add eslint-plugin-promise to detect uncaught rejections * Move alert generation for errors to actions/alert * Add missing rejection handling for Promises * Use catch() instead of onReject on then() Then it will catches rejection from onFulfilled. This detection can be disabled by `allowThen` option, though. --- .eslintrc.yml | 3 ++ app/javascript/mastodon/actions/accounts.js | 2 +- app/javascript/mastodon/actions/alerts.js | 25 ++++++++++++++++ app/javascript/mastodon/actions/compose.js | 7 ++++- app/javascript/mastodon/actions/lists.js | 3 +- .../actions/push_notifications/registerer.js | 15 ++++------ app/javascript/mastodon/actions/settings.js | 5 +++- .../mastodon/containers/status_container.js | 6 +++- .../features/ui/components/embed_modal.js | 3 ++ app/javascript/mastodon/middleware/errors.js | 24 ++------------- app/javascript/mastodon/storage/modifier.js | 30 ++++++++++++++----- package.json | 1 + yarn.lock | 4 +++ 13 files changed, 84 insertions(+), 44 deletions(-) diff --git a/.eslintrc.yml b/.eslintrc.yml index cf276a16fd..576e5b70ac 100644 --- a/.eslintrc.yml +++ b/.eslintrc.yml @@ -13,6 +13,7 @@ plugins: - react - jsx-a11y - import +- promise parserOptions: sourceType: module @@ -152,3 +153,5 @@ rules: - "app/javascript/**/__tests__/**" import/no-unresolved: error import/no-webpack-loader-syntax: error + + promise/catch-or-return: error diff --git a/app/javascript/mastodon/actions/accounts.js b/app/javascript/mastodon/actions/accounts.js index 7cacff9092..28ae567632 100644 --- a/app/javascript/mastodon/actions/accounts.js +++ b/app/javascript/mastodon/actions/accounts.js @@ -103,7 +103,7 @@ export function fetchAccount(id) { dispatch(importFetchedAccount(response.data));
