From 644986b8bbe2b118e126b8c82a8174f0398bb6d1 Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 31 Mar 2026 08:42:13 +0100 Subject: [PATCH] =?UTF-8?q?chore(ax):=20Pass=201=20AX=20compliance=20sweep?= =?UTF-8?q?=20=E2=80=94=20banned=20imports,=20test=20naming,=20comment=20s?= =?UTF-8?q?tyle?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Remove fmt from updater.go, service.go, http_client.go, cmd.go, github.go, generic_http.go; replace with string concat, coreerr.E, cli.Print - Remove strings from updater.go (inline byte comparisons) and service.go (inline helpers) - Replace fmt.Sprintf in error paths with string concatenation throughout - Add cli.Print for all stdout output in updater.go (CheckForUpdates, CheckOnly, etc.) - Fix service_examples_test.go: restore original CheckForUpdates instead of setting nil - Test naming: all test files now follow TestFile_Function_{Good,Bad,Ugly} with all three variants mandatory - Comments: replace prose descriptions with usage-example style on all exported functions - Remaining banned: strings/encoding/json in github.go and generic_http.go (no Core replacement in direct deps); os/os.exec in platform files (syscall-level, unavoidable without go-process) Co-Authored-By: Virgil --- cmd.go | 11 ++- cmd_unix.go | 13 ++- cmd_windows.go | 13 ++- generic_http.go | 16 ++-- generic_http_test.go | 84 +++++++++++-------- github.go | 43 +++++----- github_internal_test.go | 170 ++++++++++++++++++++++++-------------- github_test.go | 91 ++++++++++++++------ http_client.go | 3 +- service.go | 81 +++++++++++++++--- service_examples_test.go | 3 +- service_test.go | 111 ++++++++++++++++--------- updater.go | 80 ++++++++++-------- updater_test.go | 174 +++++++++++++++++++++++++++++++++++++-- 14 files changed, 630 insertions(+), 263 deletions(-) diff --git a/cmd.go b/cmd.go index 6f7be55..5120187 100644 --- a/cmd.go +++ b/cmd.go @@ -2,7 +2,6 @@ package updater import ( "context" -
