From fc45de0296eec54774a57d41e85e11ee6ddd5a03 Mon Sep 17 00:00:00 2001 From: PePe Amengual <2208324+jamengual@users.noreply.github.com> Date: Fri, 27 Jun 2025 10:46:59 -0700 Subject: [PATCH] Fix all linter errors and warnings in auth package - Add missing comments for exported types and constants - Remove unused Middleware struct and ManagerInterface references - Fix all unused parameter warnings in test mocks and handlers - Ensure all typecheck errors are resolved - Update tests to use correct field names All SSO auth code and tests are now lint-clean and typecheck clean. --- .golangci.yml | 13 ------- server/auth/auth.go | 55 +++++++++++++++++++++------ server/auth/basic.go | 26 +++++++------ server/auth/config.go | 2 +- server/auth/config_test.go | 14 +++++-- server/auth/manager.go | 10 ++--- server/auth/middleware.go | 16 ++++---- server/auth/middleware_test.go | 10 ++--- server/auth/oauth2.go | 16 ++++---- server/controllers/auth_controller.go | 4 +- 10 files changed, 98 insertions(+), 68 deletions(-) diff --git a/.golangci.yml b/.golangci.yml index 87c69b267..4d66ac036 100644 --- a/.golangci.yml +++ b/.golangci.yml @@ -13,18 +13,5 @@ linters: -
