 # Changelog

+## v0.4.0
+
+- **破坏性变更**：移除 Gin 适配器及其全部依赖，`omni.New()` 默认使用只依赖标准库的 `transport/nethttp`。
+- 移除 Gin 专属的 `Config.Mode` / `WithMode` API；网络层运行模式由具体适配器或启动层自行配置。
+- 公共 `httpx.Router`、`transport/transporttest.Run` 和 `omni.NewWithRouter` 保留，自研网络层无需修改业务 Handler / Service 即可接入。
+- benchmark 改为标准库路由和完整 GoOmni 请求链，新增 `scripts/verifyPerformance.py` 作为 race、vet、build 和性能基线入口。
+- 远程业务试用、脚手架、适配器契约和 MySQL 验收全部迁移到 `v0.4.0`。
+
 ## v0.3.1

 - 新增独立业务模块验收 `scripts/verifyBusiness.py`：从远程 `v0.2.0` 升级到 `v0.3.1`，验证无本地 replace、配置加载、结构化日志、requestId、CRUD、校验错误、业务错误和优雅退出。

+# GoOmni 性能基线
+
+这份基线用于比较未来自研网络层，不代表生产容量承诺。测试只测进程内请求分发和 GoOmni 请求链，不包含真实 TCP、TLS、数据库或业务存储延迟。
+
+运行：
+
+```sh
+python3 scripts/verifyPerformance.py
+```
+
+本次记录环境：Go 1.25.0、darwin/arm64、Apple M2 Max；每项连续运行 3 次：
+
+```text
+BenchmarkTransportRouteDispatch/nethttp  568–671 ns/op  1344 B/op  13 allocs/op
+BenchmarkTransportApplicationRequest/nethttp  2017–2208 ns/op  3091 B/op  34 allocs/op
+```
+
+`BenchmarkTransportRouteDispatch` 只覆盖标准库路由、路径参数和 `http.Handler` 调用；`BenchmarkTransportApplicationRequest` 还包含 GoOmni Context、RequestID、统一 JSON 响应和默认中间件链。
+
+比较新网络层时，应使用相同 Go 版本、机器和 benchmark 命令，并同时运行 `-race` 全量测试。性能下降需要结合分配次数、取消传播、错误响应和业务契约结果一起判断。

 当前替换边界是路由与 HTTP 适配层，`App.Run` 仍使用标准库 `net/http.Server`。未来自研监听、连接管理或协议解析时，可让自研服务调用 `App.ServeHTTP`（提供标准 HTTP 请求/响应桥接），由自研启动层管理监听与关闭，并在退出时调用 `App.Close`；本阶段没有实现新的网络内核。
