From 7706ed038f1a16d232635d564a28e6f90e53e0fd Mon Sep 17 00:00:00 2001 From: unarist Date: Wed, 30 May 2018 00:42:29 +0900 Subject: [PATCH] Fix context building in the reducer (#7671) This fixes below bugs: * addReply() had used native compare operator for string ids => descendants may appears at wrong position * CONTEXT_FETCH_SUCCESS had added the focused status as the reply of the *first* status in ancestors, not last status. => descendants may also appears wrong position as well as correct position * TIMELINE_UPDATE had added the status to replies of *itself* instead of replied status => browser will hangs if you open the status due to a circular reference --- app/javascript/mastodon/reducers/contexts.js | 27 ++++++++++---------- 1 file changed, 14 insertions(+), 13 deletions(-) diff --git a/app/javascript/mastodon/reducers/contexts.js b/app/javascript/mastodon/reducers/contexts.js index 53e70b58ef..4c2d6cc8a3 100644 --- a/app/javascript/mastodon/reducers/contexts.js +++ b/app/javascript/mastodon/reducers/contexts.js @@ -5,6 +5,7 @@ import { import { CONTEXT_FETCH_SUCCESS } from '../actions/statuses'; import { TIMELINE_DELETE, TIMELINE_UPDATE } from '../actions/timelines'; import { Map as ImmutableMap, List as ImmutableList } from 'immutable'; +import compareId from '../compare_id'; const initialState = ImmutableMap({ inReplyTos: ImmutableMap(), @@ -15,27 +16,27 @@ const normalizeContext = (immutableState, id, ancestors, descendants) => immutab state.update('inReplyTos', immutableAncestors => immutableAncestors.withMutations(inReplyTos => { state.update('replies', immutableDescendants => immutableDescendants.withMutations(replies => { function addReply({ id, in_reply_to_id }) { - if (in_reply_to_id) { - const siblings = replies.get(in_reply_to_id, ImmutableList()); + if (in_reply_to_id && !inReplyTos.has(id)) { - if (!siblings.includes(id)) { - const index = siblings.findLastIndex(sibling => sibling.id < id); - replies.set(in_reply_to_id, siblings.insert(index + 1, id)); - } + replies.update(in_reply_to_id, ImmutableList(), siblings => { + const index = siblings.findLastIndex(sibling => compareId(sibling, id) < 0); + return siblings.insert(index + 1, id); + }); inReplyTos.set(id, in_reply_to_id); } } + // We know in_reply_to_id of statuses but `id` itself. + // So we assume that the status of the id replies to last ancestors. + + ancestors.forEach(addReply); + if (ancestors[0]) { - addReply({ id, in_reply_to_id: ancestors[0].id }); + addReply({ id, in_reply_to_id: ancestors[ancestors.length - 1].id }); } - if (descendants[0]) { - addReply({ id: descendants[0].id, in_reply_to_id: id }); - } - - [ancestors, descendants].forEach(statuses => statuses.forEach(addReply)); + descendants.forEach(addReply); })); })); }); @@ -80,7 +81,7 @@ const updateContext = (state, status) => { mutable.setIn(['inReplyTos', status.id], status.in_reply_to_id); if (!replies.includes(status.id)) { - mutable.setIn(['replies', status.id], replies.push(status.id)); + mutable.setIn(['replies', status.in_reply_to_id], replies.push(status.id)); } }); }
