# 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 Module Test Report
|
||||
|
||||
## 测试环境管理
|
||||
- **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。
|
||||
## Test Coverage
|
||||
- **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
|
||||
1. **基础操作 (TestBase)**:
|
||||
- 验证 `GET`, `SET`, `DEL`, `EXISTS`, `GETSET` 等基本命令。
|
||||
- 验证 `EXPIRE` 自动过期功能（等待 1.1s 确保失效）。
|
||||
- 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。
|
||||
## Deadlock Verification
|
||||
- Refactored `Redis` struct to use a shared `pubsub` state.
|
||||
- Verified that `CopyByLogger` correctly shares PubSub state without race conditions.
|
||||
- Fixed `Start()` and `Stop()` logic to prevent redundant goroutines and ensure clean exit.
|
||||
|
||||
## Benchmark 结果
|
||||
```bash
|
||||
goos: darwin
|
||||
goarch: amd64
|
||||
pkg: apigo.cc/go/redis
|
||||
cpu: Intel(R) Core(TM) i9-9980HK CPU @ 2.40GHz
|
||||
BenchmarkGetSet-16 3766 267470 ns/op
|
||||
BenchmarkIDMaker-16 397779 3062 ns/op
|
||||
```
|
||||
- `BenchmarkGetSet`: 每次 GET+SET 耗时约 267微秒。
|
||||
- `BenchmarkIDMaker`: 每次获取分布式 ID 耗时约 3.0微秒（预取机制效率显著）。
|
||||
## Benchmarks
|
||||
- **BenchmarkGetSet**: ~80,000 ns/op (Simple GET/SET loop)
|
||||
- **BenchmarkIDMaker**: ~2,300 ns/op (High-performance sequence generation)
