v1.1.3 Release Notes

Released 2026-01-01

REFACTOR

• Replace Queue.closed bool + sync.RWMutex with atomic.Uint32 state
• Use CAS in Start() to ensure transition from stateCreated to stateRunning only
• Use CAS loop in Shutdown() for idempotent closure (allow multiple calls)

UPDATE

• Change Start() return type to error for state check error reporting
• Change Config.Timeout type from int64 to time.Duration
• Change default Timeout from 30 to 30 * time.Second

FIX

• Fix Enqueue() error message formatting, use %w to wrap underlying error
• Fix Shutdown() to call cancel() after completion for context cleanup

REFACTOR

• 將 Queue.closed bool + sync.RWMutex 替換為 atomic.Uint32 state
• 在 Start() 中使用 CAS 確保只能從 stateCreated 轉換到 stateRunning
• 在 Shutdown() 中使用 CAS loop 確保冪等性關閉（允許多次調用）

UPDATE

• 修改 Start() 返回型別為 error，支援狀態檢查錯誤回報
• Config.Timeout 型別從 int64 改為 time.Duration
• 預設 Timeout 值從 30 改為 30 * time.Second

FIX

• 修正 Enqueue() 錯誤訊息格式化，使用 %w 包裹底層錯誤
• 修正 Shutdown() 在完成後呼叫 cancel() 清理 context
