From 40da4e88ea24e85ffbd805fdc8d81921a9893cee Mon Sep 17 00:00:00 2001 From: Norm Date: Fri, 25 Oct 2024 11:09:20 -0400 Subject: [PATCH] Update hashtag prune to account for followed hashtags Currently pruning hashtags with the prune_objects task only accounts for whether that hashtag is associated with an object, but this may lead to a foreign key constraint violation if that hashtag has no objects but is followed by a local user. This adds an additional check to see if that hashtag has any followers before proceeding to delete it. --- lib/mix/tasks/pleroma/database.ex | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/lib/mix/tasks/pleroma/database.ex b/lib/mix/tasks/pleroma/database.ex index 87ccfdff1..f85fe5bea 100644 --- a/lib/mix/tasks/pleroma/database.ex +++ b/lib/mix/tasks/pleroma/database.ex @@ -346,7 +346,10 @@ def run(["prune_objects" | args]) do DELETE FROM hashtags AS ht WHERE NOT EXISTS ( SELECT 1 FROM hashtags_objects hto - WHERE ht.id = hto.hashtag_id) + WHERE ht.id = hto.hashtag_id + UNION + SELECT 1 FROM user_follows_hashtag ufht + WHERE ht.id = ufht.hashtag_id) """ |> Repo.query!()
