背景 当前 Dubbo Website 的 Go SDK 文档中已有 AOP 与可扩展机制，主要介绍： common/extension 注册中心； extension.SetFilter / GetFilter； init() 注册机制； imports 包； 自定义 filter、router、protocol、registry 的基本注册方式。 但目前缺少面向用户的 extension 使用文档，尤其没有覆盖 dubbo-go#3687 引入的统一 extension 配置和 option API。 相关实现： dubbo-go#3687 dubbo-go-extensions Hystrix dubbo-go-extensions Hystrix migration issue 需要补充的内容 1. 统一 extension API 说明以下入口的职责和使用场景： dubbo.WithExtension(...) client.WithExtension(...) server.WithExtension(...) 需要明确： dubbo.WithExtension 对应 InstanceScope； client.WithExtension 对应 ClientScope / consumer； server.WithExtension 对应 ServerScope / provider； consumer/provider 不需要用户额外传 role； extension option 由具体扩展包定义； dubbo-go 核心只接收通用 extension.Optio
背景 依赖 dubbo-go#3687 提供的统一 extension config/option API，将当前 filter/hystrix 从旧的手工配置方式迁移到新的 extension 配置模型。 当前实现要求用户： 直接依赖并调用 github.com/afex/hystrix-go/hystrix.ConfigureCommand； 自己区分并配置 hystrix_consumer / hystrix_provider； 在 client/server 上手动调用 client.WithFilter / server.WithFilter； 手工使用带有 dubbo:consumer: / dubbo:provider: 前缀的 command name。 当前实现： filter/hystrix/filter.go filter/hystrix/README.md filter/hystrix/README_CN.md 目标 将 Hystrix 迁移为 dubbo-go 新的 extension config/option 使用方式： 用户不再直接调用 hystrix.ConfigureCommand； 用户不再直接依赖 hystrix_consumer / hystrix_provider filter name； 用户通过 client.WithExtension 或 server.WithExtension 使用 Hystrix； 用户可以通过 dubbo.Load() 加载 Hystrix YAML 配置； consumer/provider 由调用入口和 YAML 层级明确区分

背景 dubbo-go 当前依赖图中仍有多项较旧版本，部分来自 gost 的 go.mod，部分直接存在于 dubbo-go/go.mod。需要做一次有边界的依赖升级，优先处理官方 SDK、旧版本和安全/兼容性风险。 本 issue 只处理依赖更新和回归验证，不负责把 API 迁移到标准库。 升级清单 以下版本以 issue 创建时的依赖检查结果为基线，最终版本应通过 go list -m -u 和兼容性验证确认。 重点依赖 当前 建议 go.etcd.io/etcd/api/v3 v3.5.7 与 client/v3 一起升级到稳定且兼容的版本 go.etcd.io/etcd/client/v3 v3.5.7 优先评估 v3.5.x/v3.6.x，随后评估 v3.7.x；保持 api/client 版本一致 github.com/nacos-group/nacos-sdk-go/v2 v2.2.5 升级到当前 v2.3.x 稳定版本 go.yaml.in/yaml/v4 v4.0.0-rc.6 跟进 v4 稳定版本；同时清理不必要的 gopkg.in/yaml.v2 间接依赖 go.uber.org/zap v1.21.0 升级到当前 v1.28.x github.com/sirupsen/logrus v1.9.4 升级到当前
背景 这批任务面向 OSPP 新人，目标是通过小 PR 补齐 Dubbo-Go 中面向用户的导出注释，并补充对应模块的单测覆盖。 需要在评论区里面评论【认领 + 任务序号】 未认领的 PR 不予接受 AI 生成的 PR 不予接受 对 OSPP 感兴趣的同学一定要通过 README 里面的方式加群沟通 please note that a complete AI PR is not welcome. 目标仓库： dubbo-go https://github.com/apache/dubbo-go 提交 PR 的时候 @Alanxtl，我到时候会去看。 任务总览 序号 任务名称 负责人 任务链接 1 补齐 Metrics Options / Error Classifier 注释与单测覆盖 @tangerineyu #3665 2 补齐 Metrics Probe 注释与单测覆盖 待认领 查看任务 3 补齐 Registry Options 注释与单测覆盖 @641-git641 #3653 4 补齐 Service Discovery Metadata Customizer 注释与单测覆盖 待认领 查看任务 5 补齐 Service Discovery Instance Customizer 注释与单测覆盖 待认领 查看任务 6 补齐 Meta
