From 91892ec18b50f0ec773faeee5871a2bd8b34bc5d Mon Sep 17 00:00:00 2001 From: Luke Barnard Date: Wed, 29 Mar 2017 14:29:41 +0100 Subject: [PATCH] Do not assume getTs will return comparable integer Fixes https://github.com/vector-im/riot-web/issues/3529. In the worst case, tsOfNewestEvent will return MAX_SAFE_INTEGER, instead of undefined, as may be the case of some events that were redacted and persisted in indexDB before changes were made to how events are redacted locally. (The important change is that events are now not stripped of their `origin_server_ts`). --- src/components/structures/RoomSubList.js | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-) diff --git a/src/components/structures/RoomSubList.js b/src/components/structures/RoomSubList.js index 3aae164a19..4aa9ff0052 100644 --- a/src/components/structures/RoomSubList.js +++ b/src/components/structures/RoomSubList.js @@ -156,9 +156,10 @@ var RoomSubList = React.createClass({ tsOfNewestEvent: function(room) { for (var i = room.timeline.length - 1; i >= 0; --i) { var ev = room.timeline[i]; - if (Unread.eventTriggersUnreadCount(ev) || - (ev.sender && ev.sender.userId === MatrixClientPeg.get().credentials.userId)) - { + if (ev.getTs() && + (Unread.eventTriggersUnreadCount(ev) || + (ev.getSender() === MatrixClientPeg.get().credentials.userId)) + ) { return ev.getTs(); } } @@ -166,7 +167,7 @@ var RoomSubList = React.createClass({ // we might only have events that don't trigger the unread indicator, // in which case use the oldest event even if normally it wouldn't count. // This is better than just assuming the last event was forever ago. - if (room.timeline.length) { + if (room.timeline.length && room.timeline[0].getTs()) { return room.timeline[0].getTs(); } else { return Number.MAX_SAFE_INTEGER;
