From 265ee88f34e8aec4c242af5b6c428bd1331fa354 Mon Sep 17 00:00:00 2001 From: Eric Eastwood Date: Mon, 10 Jun 2024 09:48:38 -0500 Subject: [PATCH] Wrong retention policy being used when filtering events (lint `ControlVarUsedAfterBlockViolation` `WPS441`) (#17272) Fix loop var being used outside block. Before this change, we were always using the last room_id's retention policy for all events being filtered. I found this bug with the [new lint rule, `ControlVarUsedAfterBlockViolation` `WPS441`](https://github.com/astral-sh/ruff/pull/11769), that I re-implemented in `ruff`. Shout-out to @reivilibre for all the help in the beginning! ### Pull Request Checklist * [x] Pull request is based on the develop branch * [x] Pull request includes a [changelog file](https://element-hq.github.io/synapse/latest/development/contributing_guide.html#changelog).
