From 04da8bb63a5df361638978c9897536e85005ea45 Mon Sep 17 00:00:00 2001 From: Eric Lewis Date: Sun, 21 Feb 2016 21:45:28 +0000 Subject: [PATCH] Posts: Non-trashed posts should take slug priority over trashed posts. When determining a unique post slug, trashed posts are taken into account. Previously, new posts would add suffixes to their slugs (e.g. `about-2`) when a post in the trash had the desired slug (e.g. `about`). To avoid this behavior, when a post is trashed its slug (i.e. `post_name`) is now suffixed with `-%trashed%`. The post's pre-trash slug is stored as post meta, and if the post is restored from trash, its desired slug is reapplied. For existing trashed posts which don't have the `-%trashed%` suffix, the suffix is added when a post with its desired slug is created.
