Quick Task 13: Fix Linting Issues Summary

One-liner: Zero golangci-lint issues via mechanical fixes across 12 Go files (errcheck, golines, gofumpt, wsl, nlreturn, intrange, unused)

What Was Done

Fixed all 31+ golangci-lint issues across 12 files with zero behavioral changes:

Issue Categories Fixed

Category	Count	Fix
errcheck	4	Assign error returns to _ (db.Close, tmp.Close, os.Remove)
golines	10+	Break long lines (t.Errorf, SQL strings, struct literals)
gofumpt	1	Reformat ScanProgress struct literal (orphans phase)
wsl	17	Add blank lines before declarations, ranges, if-statements; remove trailing comments before }
nlreturn	3	Add blank line before return statements
intrange	2	Convert for i := 0; i < n; i++ to for i := range n
unused	2	Remove unused artistEntry and albumEntry type definitions

Files Modified

Main source files (3):

• backend/database/testhelper.go — errcheck fix for db.Close()
• backend/events/cmd/genevents/main.go — errcheck, nlreturn, wsl, gofumpt fixes
• backend/library/library.go — gofumpt struct formatting, wsl spacing

Test files (9):

• backend/database/search_test.go — golines, unused types, wsl fixes
• backend/config/config_test.go — golines, wsl trailing comment fix
• backend/queue/navigation_test.go — intrange, golines, wsl fixes
• backend/queue/queue_test.go — intrange, nlreturn, golines fixes
• backend/queue/persistence_test.go — golines fixes
• backend/library/scan_test.go — golines, wsl fixes
• backend/favorites/config_test.go — wsl fix
• backend/theme/config_test.go — wsl fixes
• backend/player/volume_test.go — golines fixes

e1a95e6	fix(quick-13): resolve lint issues in main source files

Note: All 12 files committed atomically because the pre-commit hook runs golangci-lint run ./... globally — partial commits would fail while unfixed files remain in the working tree.

Deviations from Plan

Auto-fixed Issues

1. [Rule 3 - Blocking] Additional files needed for global lint pass

• Found during: Task 1 commit
• Issue: The pre-commit hook runs golangci-lint run ./... across the entire codebase. The plan listed 8 files, but 4 additional test files (favorites/config_test.go, theme/config_test.go, player/volume_test.go, queue/persistence_test.go) also had golines/wsl issues that blocked any commit.
• Fix: Fixed all issues in the additional files alongside the planned files.
• Files modified: backend/favorites/config_test.go, backend/theme/config_test.go, backend/player/volume_test.go, backend/queue/persistence_test.go

2. [Rule 3 - Blocking] Codegen-check hook failure from pre-existing unstaged changes

• Found during: Task 1 commit
• Issue: The codegen-check pre-commit hook runs git diff --name-only and fails if ANY uncommitted changes exist. Pre-existing frontend TypeScript changes (from previous sessions) caused this check to fail.
• Fix: Temporarily stashed the pre-existing frontend changes, committed the lint fixes, then restored the stash. No files were modified or lost.

3. [Rule 3 - Blocking] Single commit for both tasks

• Found during: Task 1 commit
• Issue: The global golangci-lint run ./... check in the pre-commit hook means ALL Go files must be lint-clean for ANY commit. Cannot commit source files separately from test files.
• Fix: Combined both tasks into a single atomic commit.

Verification

• golangci-lint run ./... → 0 issues
• go test ./backend/... → all packages pass
• No behavioral changes to any code

Self-Check: PASSED
