### ✅ 验证清单 - [x] 🔍 我已经搜索过 [现有 Issues](https://github.com/apache/dubbo-go/issues)，确信这不是重复问题 ### 🚀 Go 版本 1.25.5 ### 📦 Dubbo-go 版本 v3.3.1 ### 🖥️ 服务端配置 _No response_ ### 💻 客户端配置 _No response_ ### 🌐 协议配置 _No response_ ### 📋 注册中心配置 _No response_ ### 💾 操作系统 🍎 macOS ### 📝 Bug 描述 客户端程序运行调用 triple 协议，服务会崩溃，报错「fatal error: concurrent map writes」 ### 🔄 重现步骤 ``` func TestClone(t *testing.T) { u1, _ := NewURL("dubbo://127.0.0.1:20000/com.ikurento.user.UserProvider?interface=com.ikurento.user.UserProvider&group=&version=2.6.0&configVersion=1.0") u1.SetAttribute("hello", "world") for i := 0; i < 1000; i++ { go func() { u1.Clone() }() } time.Sleep(2 * time.Second) } ``` 执行 `go test -trimpath -race -v -run TestClone -timeout 30s | head -n 100` 运行结果 ``` === RUN TestClone ================== WARNING: DATA RACE Write at 0x00c0000a1920 by goroutine 34: runtime.mapaccess2_faststr() internal/runtime/maps/runtime_faststr_swiss.go:162 +0x29c dubbo.apache.org/dubbo-go/v3/common.(*URL).SetAttribute() dubbo.apache.org/dubbo-go/v3/common/url.go:568 +0x100 dubbo.apache.org/dubbo-go/v3/common.(*URL).Clone.func2() dubbo.apache.org/dubbo-go/v3/common/url.go:883 +0x4c dubbo.apache.org/dubbo-go/v3/common.(*URL).RangeAttributes() dubbo.apache.org/dubbo-go/v3/common/url.go:893 +0x144 dubbo.apache.org/dubbo-go/v3/common.(*URL).Clone() dubbo.apache.org/dubbo-go/v3/common/url.go:882 +0x148 dubbo.apache.org/dubbo-go/v3/common.TestClone.func1() dubbo.apache.org/dubbo-go/v3/common/url_test.go:421 +0x2c ``` ### ✅ 预期行为 代码正常运行，无并发问题。 ### ❌ 实际行为 提示 Data Race，有并发问题。 ### 💡 可能的解决方案 修复 Clone() 逻辑，去掉 copier.Copy() 的浅拷贝，通过加锁和直接赋值避免 map 的浅拷贝。 -- This is an automated message from the Apache Git Service.
