For this, we now (1) only allows Updates to poll counts if there is no updated field, or the updated field is the same as the last updated date or creation date; (2) does not allow updating anything if the updated field is older than the last updated date or creation date; (3) allows updating updatable fields otherwise (normal updates); (4) if only the updated field is changed, it does not create a new history item on its own. --- .../pleroma/web/activity_pub/side_effects_test.exs | 96 +++++++++++++++++++++- test/pleroma/web/common_api_test.exs | 2 +- 2 files changed, 93 insertions(+), 5 deletions(-) (limited to 'test') diff --git a/test/pleroma/web/activity_pub/side_effects_test.exs b/test/pleroma/web/activity_pub/side_effects_test.exs index 8e84db774..3b313b769 100644 --- a/test/pleroma/web/activity_pub/side_effects_test.exs +++ b/test/pleroma/web/activity_pub/side_effects_test.exs @@ -142,14 +142,19 @@ defmodule Pleroma.Web.ActivityPub.SideEffectsTest do describe "update notes" do setup do + make_time = fn -> + Pleroma.Web.ActivityPub.Utils.make_date() + end + user = insert(:user) -
