 # CHANGELOG - redis
 
+## v1.0.3 (2026-05-05)
+- **PubSub Robustness**:
+  - 重构 `Redis` 结构体，引入 `pubsub` 内部结构管理共享状态。
+  - 修复了 `CopyByLogger` 场景下 `subs` map 与 `subLock` 不匹配导致的并发竞争风险。
+  - 优化 `Start()` 方法，增加运行状态检查，防止冗余的订阅协程启动。
+  - 增强 `Stop()` 方法的生命周期管理，确保协程安全退出并清理停止通道。
+
 ## v1.0.2 (2026-05-04)
 - **Naming Standardization**:
   - 全面将 `Id` 命名规范化为 `ID`（涉及 `IDMaker`, `NewIDMaker`, `userInfo.ID` 等）。

-# redis 模块测试报告
+# Redis Module Test Report
 
-## 测试环境管理
+## Test Coverage
-- **自动环境检查 (TestMain)**: 测试启动时会自动检查 `localhost:6379` 的 Redis 服务。如果不可用，将打印跳过信息并退出，避免测试在无环境时报错。
+- **Base Operations**: GET, SET, SETEX, DEL, EXISTS, EXPIRE, etc. (Verified in `TestBase`)
+- **Distributed ID**: Integrated with `go/id`, supports high-concurrency pre-fetching. (Verified in `TestIDMaker`)
+- **Generics**: Type-safe result binding using `To[T]`. (Verified in `TestGenerics`)
+- **Pub/Sub**: Thread-safe publish and subscribe with automatic re-connection. (Verified in `TestSub`)
+- **Robustness**: Automatic retry on network failure/server restart. (Verified in `TestRetry`)
 
-## 测试场景
+## Deadlock Verification
-1. **基础操作 (TestBase)**:
+- Refactored `Redis` struct to use a shared `pubsub` state.
-   - 验证 `GET`, `SET`, `DEL`, `EXISTS`, `GETSET` 等基本命令。
+- Verified that `CopyByLogger` correctly shares PubSub state without race conditions.
-   - 验证 `EXPIRE` 自动过期功能（等待 1.1s 确保失效）。
+- Fixed `Start()` and `Stop()` logic to prevent redundant goroutines and ensure clean exit.
-   - 验证结构体自动序列化与反序列化。
-   - 验证 `MSET`, `MGET` 批量操作。
-2. **分布式 ID (TestIdMaker)**:
-   - 验证 `NewIdMaker` 结合 Redis 生成唯一 ID 的能力。
-   - 验证生成 200 个 ID 无碰撞。
-   - 验证 `GetForMysql` 和 `GetForPostgreSQL` 的长度与格式。
-3. **泛型支持 (TestGenerics)**:
-   - 验证 `To[T]` 泛型函数对结果的反序列化。
-4. **发布订阅 (TestSub)**:
-   - 验证 `Subscribe`, `Unsubscribe`, `PUBLISH` 功能。
-   - 验证并发订阅与取消订阅的稳定性。
 
-## Benchmark 结果
