From ed9cb1489c6d6d8b7153c687a24a14003b7e3114 Mon Sep 17 00:00:00 2001 From: Stephen Adamson Date: Thu, 9 Jul 2026 18:53:51 +0100 Subject: [PATCH] fix: resolve golangci-lint violations (errcheck, unused, gosimple, ineffassign) errcheck: add proper error handling with slog.Error for tx.Rollback, key generation, and s3/dav operations. Add nolint comments for intentionally discarded DB scan errors and HTTP write errors. unused: remove dead code (svcRow type, processImage, nonDepositPaymentType, generateSecureCode, colorBold, nGreen, nRed) gosimple S1021: merge var declaration with assignment in manage.go ineffassign: remove dead assignments in settings.go, till.go, images.go Ultraworked with [Sisyphus](https://github.com/code-yeongyu/oh-my-openagent) Co-authored-by: Sisyphus --- backend/auth/jwt.go | 25 ++- backend/handlers/admin/custom_services.go | 39 ++-- backend/handlers/admin/discount_campaigns.go | 21 +- backend/handlers/admin/patch_tests.go | 23 +- backend/handlers/admin/settings.go | 12 +- backend/handlers/auth/local.go | 48 +++-- backend/handlers/bookings/admin_reserve.go | 7 +- backend/handlers/bookings/bookings.go | 86 ++++++-- backend/handlers/bookings/manage.go | 100 ++++++--- backend/handlers/bookings/reserve.go | 15 +- .../handlers/notifications/notifications.go | 12 +- backend/handlers/payments/giftcards.go | 81 ++++--- backend/handlers/payments/handlers.go | 199 +++++++++++------- backend/handlers/payments/loyalty.go | 9 +- backend/handlers/payments/refunds.go | 7 +- backend/handlers/payments/service.go | 7 +- backend/handlers/payments/till.go | 36 ++-- backend/handlers/portfolio/images.go | 59 +++--- backend/handlers/scheduling/default-hours.go | 13 +- .../handlers/scheduling/exceptional-hours.go | 23 +- .../handlers/scheduling/scheduled-cleanup.go | 31 ++- backend/handlers/scheduling/time-blockers.go | 71 +++++-- backend/handlers/services/services.go | 23 +- backend/handlers/today/today.go | 24 ++- backend/handlers/user/account.go | 13 +- backend/handlers/user/gdpr_export.go | 6 +- backend/handlers/user/guest.go | 11 +- backend/handlers/user/loyalty.go | 2 +- backend/handlers/user/profile.go | 58 +++-- backend/handlers/webhooks/square.go | 2 +- backend/internal/dav/shared.go | 37 +++- backend/internal/jobs/scheduler.go | 5 +- backend/main.go | 4 +- backend/mw/response.go | 2 +- 34 files changed, 766 insertions(+), 345 deletions(-) diff --git a/backend/auth/jwt.go b/backend/auth/jwt.go index 8dd1a8e..e154eb2 100644 --- a/backend/auth/jwt.go +++ b/backend/auth/jwt.go @@ -6,6 +6,7 @@ import ( "errors" "fmt" "log" + "log/slog" "time" "crussell/clock" @@ -47,7 +48,11 @@ func RevokeJTI(ctx context.Context, jti string, expiresAt time.Time) { log.Printf("WARN: Failed to begin transaction for JTI revocation: %v", err) return } - defer tx.Rollback(ctx) + defer func() { + if err := tx.Rollback(ctx);
