From 764bf991d5a99711a966415fc0c829d2ba148f7c Mon Sep 17 00:00:00 2001 From: Claire Date: Sun, 23 Jan 2022 13:53:58 +0100 Subject: [PATCH] Remove old duplicate index (#17245) Some Mastodon versions (v1.1 and v1.2) had a duplicate index in `db/schema.rb` without any migration script creating it. #2224 (included in v1.3) removed the duplicate index from the file but did not provide a migration script to remove it. This means that any instance that was installed from v1.1 or v1.2's source code has a duplicate index and a corresponding warning in PgHero. Instances set up using an earlier or later Mastodon version do not have this issue. This PR removes the duplicate index if it is present. --- .../20220105163928_remove_mentions_status_id_index.rb | 9 +++++++++ 1 file changed, 9 insertions(+) create mode 100644 db/migrate/20220105163928_remove_mentions_status_id_index.rb diff --git a/db/migrate/20220105163928_remove_mentions_status_id_index.rb b/db/migrate/20220105163928_remove_mentions_status_id_index.rb new file mode 100644 index 00000000000000..56e903719288d4 --- /dev/null +++ b/db/migrate/20220105163928_remove_mentions_status_id_index.rb @@ -0,0 +1,9 @@ +class RemoveMentionsStatusIdIndex < ActiveRecord::Migration[6.1] + def up + remove_index :mentions, name: :mentions_status_id_index if index_exists?(:mentions, :status_id, name: :mentions_status_id_index) + end + + def down + # As this index should not exist and is a duplicate of another index, do not re-create it + end +end
