From 9356ec0cc5afc95a8fd398ddf898942ef0acdb74 Mon Sep 17 00:00:00 2001 From: Eric Wong Date: Fri, 4 Dec 2020 12:09:29 +0000 Subject: over: ensure old, merged {tid} is really gone We must use the result of link_refs() since it can trigger merge_threads() and invalidate $old_tid. In case merge_threads() isn't triggered, link_refs() will return $old_tid anyways. When rethreading and allocating new {tid}, we also must update the row where the now-expired {tid} came from to ensure only the new {tid} is seen when reindexing subsequent messages in history. Otherwise, every subsequently reindexed+rethreaded message could end up getting a new {tid}.
