From 944f1ec54c7ffc3c7e9c530392a26fd98f7ce635 Mon Sep 17 00:00:00 2001 From: Giteabot Date: Fri, 19 Apr 2024 15:18:11 +0800 Subject: [PATCH] Avoid importing `modules/web/middleware` in `modules/session` (#30584) (#30588) Backport #30584 by @wolfogre Related to #30375. It doesn't make sense to import `modules/web/middleware` and `modules/setting` in `modules/web/session` since the last one is more low-level. And it looks like a workaround to call `DeleteLegacySiteCookie` in `RegenerateSession`, so maybe we could reverse the importing by registering hook functions.
