From d3660b24d37862bb58cf309c582cfe7432fd7bb6 Mon Sep 17 00:00:00 2001 From: rinpatch Date: Mon, 22 Mar 2021 20:07:07 +0300 Subject: [PATCH] Copy emoji in the subject from parent post Sometimes people put emoji in the subject, which results in the subject looking broken if someone replies to it from a server that does not have the said emoji under the same shortcode. This patch solves the problem by extending the emoji set available in the summary to that of the parent post. --- lib/pleroma/web/common_api/activity_draft.ex | 27 ++++++++++ .../fixtures/tesla_mock/emoji-in-summary.json | 49 +++++++++++++++++++ test/pleroma/web/common_api_test.exs | 26 ++++++++++ test/support/http_request_mock.ex | 9 ++++ 4 files changed, 111 insertions(+) create mode 100644 test/fixtures/tesla_mock/emoji-in-summary.json diff --git a/lib/pleroma/web/common_api/activity_draft.ex b/lib/pleroma/web/common_api/activity_draft.ex index 8668b600e..80a9fa7bb 100644 --- a/lib/pleroma/web/common_api/activity_draft.ex +++ b/lib/pleroma/web/common_api/activity_draft.ex @@ -5,6 +5,7 @@ defmodule Pleroma.Web.CommonAPI.ActivityDraft do alias Pleroma.Activity alias Pleroma.Conversation.Participation + alias Pleroma.Object alias Pleroma.Web.CommonAPI alias Pleroma.Web.CommonAPI.Utils @@ -186,6 +187,32 @@ defp sensitive(draft) do defp object(draft) do emoji = Map.merge(Pleroma.Emoji.Formatter.get_emoji_map(draft.full_payload), draft.emoji) + # Sometimes people create posts with subject containing emoji, + # since subjects are usually copied this will result in a broken + # subject when someone replies from an instance that does not have + # the emoji or has it under different shortcode.
