|
|-------|------|-------------|
|
|
| `unnamedResult` | `errors.go:63` | Added named return values |
|
|
| `equalFold` | `errors.go:70` | Changed to `strings.EqualFold()` |
|
|
| `S1031 nil check` | `errors.go:48` | Removed unnecessary nil check |
|
|
| `httpNoBody` (4x) | `db_health_handler_test.go` | Changed `nil` to `http.NoBody` |

## Test Coverage
|
|
|
|
| Package | Coverage |
|
|
|---------|----------|
|
|
| `internal/database` | **87.0%** |
|
|
| `internal/api/handlers` | **83.2%** |
|
|
| `internal/services` | **83.4%** |
|
|
|

|
## API Endpoint Verification
|
|
|
|
The new `/api/v1/health/db` endpoint returns:
|
|
|
|
```json
|
|
{
|
|
"status": "healthy",
|
|
"integrity_ok": true,
|
|
"integrity_result": "ok",
|
|
"wal_mode": true,
|
|
"journal_mode": "wal",
|
|
"last_backup": "2025-12-17T15:00:00Z",
|
|
"checked_at": "2025-12-17T15:30:00Z"
|
|
}
|
|
```
|
|
|
|
✅ All JSON fields use `snake_case` as required.
|
|
|
|

|
|
|
|
## Issues Found & Resolved
|
|
|
|
1. **Lint: `unnamedResult`** - Function `CheckIntegrity` now has named return values for clarity.
|
|
2. **Lint: `equalFold`** - Used `strings.EqualFold()` instead of `strings.ToLower() == "ok"`.
|
|
3. **Lint: `S1031`** - Removed redundant nil check before range (Go handles nil maps safely).
|
|
4. **Lint: `httpNoBody`** - Test requests now use `http.NoBody` instead of `nil`.
