From d559fd9f4d731a6f1d220873d9a59e98528e3efa Mon Sep 17 00:00:00 2001 From: Pranshu Srivastava Date: Fri, 22 Mar 2024 02:00:47 +0530 Subject: [PATCH 1/3] *: `s/(%v|%s)/%w` for all `fmt.Errorf` errors The `%w` verb was introduced in `go1.20` which allows for error wrapping. However, even though the minimum supported version was specified as `go1.19` there are already sparse occurences of the `%w` verb throughout the codebase. Hence it's safe to move the minimum supported version to `go1.20` since its constructs have been in use within the repository for a while now.
