Task 1管理 usecase 的操作端口与 DTO3.1 先读包级流程文档实施的第一步是重新阅读相关包的流程文档理解 repair 与运行时状态语义cat internal/runtime/channelmeta/FLOW.md cat pkg/channel/FLOW.md cat pkg/channel/replica/FLOW.md说明计划撰写时这些文件存在于上述路径当前仓库内部结构已随工程演进重组internal/runtime下的包已调整为channelappend、delivery、mqttsession等组织方式读包级 FLOW 的意图是动手前先理解语义边界这一做法仍然适用。3.2 两个窄操作端口在internal/usecase/management的 App 选项与结构中新增两个带文档注释的端口type ChannelReplicaStatusReader interface { // ChannelRuntimeStatus returns the best proven runtime status for one channel. ChannelRuntimeStatus(ctx context.Context, id channel.ChannelID) (channel.ChannelRuntimeStatus, error) } type ChannelLeaderRepairOperator interface { // RepairChannelLeader repairs or validates authoritative channel leader metadata. RepairChannelLeader(ctx context.Context, req RepairChannelClusterLeaderRequest) (RepairChannelClusterLeaderResult, error) }并在Options与App中增加字段ChannelReplicaStatus ChannelReplicaStatusReader ChannelLeaderRepair ChannelLeaderRepairOperator命名上刻意避开了既有ChannelRuntimeMeta相关名称防止与已有的元数据读取能力冲突。从当前仓库看internal/usecase/management的App结构已演进为分组依赖模式见 internal/usecase/management/nodes.go 中type App struct的nodeManagementDeps、channelManagementDeps、userManagementDeps、messageManagementDeps、operationsManagementDeps分组以及New(opts Options)的注入方式。P0.5 端口在落地时会以相同风格并入对应分组本文保留计划中的原始接口形状便于对照设计意图。3.3 副本详情 DTO 与方法计划定义了完整的副本详情 DTO数值指针字段在未知时保持nilHTTP 层序列化为nulltype ChannelClusterReplicaStatus struct { // NodeID is the replica node ID. NodeID uint64 // Role is leader or follower from authoritative metadata. Role string // IsLeader reports whether this replica is the authoritative leader. IsLeader bool // InISR reports whether this replica is in the authoritative ISR set. InISR bool // Reported reports whether live runtime status was proven for this replica. Reported bool // CommitSeq is the proven committed sequence for this replica, when known. CommitSeq *uint64 // LEO is the proven log end offset for this replica, when known. LEO *uint64 // CheckpointHW is the proven durable checkpoint high watermark, when known. CheckpointHW *uint64 // Lag is leader commit minus replica commit, when both are known. Lag *uint64 } type ChannelClusterReplicaDetail struct { // Channel is authoritative manager channel metadata. Channel ChannelRuntimeMetaDetail // RuntimeReported reports whether a runtime status source proved a live status. RuntimeReported bool // CommitSeq is the proven leader/local committed sequence, when known. CommitSeq *uint64 // MinAvailableSeq is the proven minimum readable sequence, when known. MinAvailableSeq *uint64 // RetentionThroughSeq is the proven retention boundary, when known. RetentionThroughSeq *uint64 // Replicas contains one row for each authoritative replica. Replicas []ChannelClusterReplicaStatus }方法签名与实现要点func (a *App) GetChannelClusterReplicaDetail(ctx context.Context, channelID string, channelType int64) (ChannelClusterReplicaDetail, error)先复用既有a.GetChannelRuntimeMeta取得权威详情该方法在当前仓库 internal/usecase/management/channel_runtime_meta.go 中有完整实现校验 channelID/channelType、LocalControlSnapshot定位 Slot、GetChannelRuntimeMeta取行、再经managerChannelRuntimeMetaItems组装 DTO若a.channelReplicaStatus为nil直接返回RuntimeReportedfalse的行且不报错状态读取器返回channel.ErrNotReady、channel.ErrStaleMeta、channel.ErrInvalidConfig时一律视为未报告状态而非端点失败。这里体现的语义是只要权威元数据存在端点就必须成功返回运行时状态只是能证明多少报多少。3.4 对应的测试只报已证明的运行时状态计划为该方法设计的测试用例TestGetChannelClusterReplicaDetailReportsOnlyProvenRuntimeStatus是理解保守策略的最佳样例fake 权威元数据channelroom-1type2slot9leader1replicas[1,2,3]ISR[1,2]MinISR2状态 active经 fake 消息读取器得到 max seq42fake 状态读取器返回channel.ChannelRuntimeStatus{Leader: 1, HW: 42, CommittedSeq: 42, MinAvailableSeq: 1, RetentionThroughSeq: 0}。断言内容Channel.HashSlot由 fake cluster 填充RuntimeReported trueCommitSeq、MinAvailableSeq、RetentionThroughSeq均非 nil 且与运行时状态一致节点1的行Reportedtrue、IsLeadertrue、Roleleader、CommitSeq42、Lag0节点2、3的行Reportedfalse、角色follower、未知数值指针全部为 nil。这条用例精确锁定了follower 未证明 → 不填数值的行为。4. Task 2安全的 Leader 修复 usecase4.1 修复请求/结果 DTO 与包级错误type RepairChannelClusterLeaderRequest struct { // ChannelID identifies the channel to repair. ChannelID string // ChannelType identifies the channel type to repair. ChannelType int64 // Reason is the manager-facing reason that requested repair. Reason string } type RepairChannelClusterLeaderResult struct { // Changed reports whether authoritative metadata changed. Changed bool // Meta is authoritative metadata after repair or validation. Meta metadb.ChannelRuntimeMeta } type RepairChannelClusterLeaderResponse struct { // Changed reports whether authoritative metadata changed. Changed bool // Channel is authoritative manager metadata after repair or validation. Channel ChannelRuntimeMetaDetail }新增包级错误哨兵var ErrUnsupportedChannelClusterRepairReason errors.New(management: unsupported channel cluster repair reason)方法签名func (a *App) RepairChannelClusterLeader(ctx context.Context, req RepairChannelClusterLeaderRequest) (RepairChannelClusterLeaderResponse, error)4.2 校验与原因映射规则实现必须遵守以下规则参数校验ChannelID非空、ChannelType 0先读后修修复前先加载当前 detail/meta允许修复的场景Reason为空且当前Leader0或Reason为ChannelClusterUnhealthyReasonNoLeader即no_leader拒绝的场景单独以isr_insufficient、status_not_active发起修复一律返回ErrUnsupportedChannelClusterRepairReason——Leader 修复既不会补 ISR 成员也不处理非 active 生命周期问题操作符缺失若 operator 为 nil返回channel.ErrInvalidConfig结果转换将返回的权威 meta 复用与GetChannelRuntimeMeta相同的转换路径转为ChannelRuntimeMetaDetail必要时抽小 helper 避免重复转换。4.3 三条修复测试用例测试场景断言TestRepairChannelClusterLeaderMapsNoLeaderToSafeRepair权威 metaLeader0、replicas[1,2]、ISR[2]fake operator 记录请求并返回Leader2、LeaderEpoch1的新 meta响应Changedtrue、返回 leader2、operator 收到no_leader或实现中映射的运行时兼容原因TestRepairChannelClusterLeaderSkipsISRInsufficientOnly已存在 Leader 的频道提交isr_insufficient返回metadb.ErrInvalidArgument或ErrUnsupportedChannelClusterRepairReasonTestRepairChannelClusterLeaderReturnsNoSafeCandidatefake operator 返回channel.ErrNoSafeChannelLeader错误原样保留这三条用例分别锁定了正确触发修复拒绝不支持的原因保留无安全候选错误三类行为。4.4 原因映射的语义来自设计规范P0 的 unhealthy 原因是 manager 面向的字符串而修复必须使用 runtime 的 channel leader repair 原因。设计规范明确no_leader→ 映射到既有的缺失/死亡 Leader 修复策略路径isr_insufficient单独出现 →不显示修复按钮Leader 修复不会新增 ISR 成员status_not_active单独出现 →不显示修复按钮非 active 生命周期不属于 Leader 修复问题。设计原则不发明新的 runtime 原因能复用既有原因就复用。5. Task 3暴露 Manager HTTP 操作路由5.1 Management 接口扩展在internal/access/manager/server.go的Management接口上增加两个方法英文注释GetChannelClusterReplicaDetail(ctx context.Context, channelID string, channelType int64) (managementusecase.ChannelClusterReplicaDetail, error) RepairChannelClusterLeader(ctx context.Context, req managementusecase.RepairChannelClusterLeaderRequest) (managementusecase.RepairChannelClusterLeaderResponse, error)5.2 HTTP DTOsnake_case JSONinternal/access/manager/channel_cluster_operations.go中定义type ChannelClusterReplicaDetailResponse struct { ... } type ChannelClusterReplicaStatusDTO struct { ... } type RepairChannelClusterLeaderRequestDTO struct { Reason string json:reason } type RepairChannelClusterLeaderResponseDTO struct { Changed bool json:changed; Channel ChannelRuntimeMetaDTO/Detail DTO }关键规则指针数值字段在未知时必须编码为null。5.3 路由注册与权限读路由加入既有 channel cluster 读组channelCluster.GET(/channel-cluster/:channel_type/:channel_id/replicas, s.handleChannelClusterReplicas)写路由新建独立写组并挂写权限channelClusterWrites : s.engine.Group(/manager) if s.auth.enabled() { channelClusterWrites.Use(s.requirePermission(cluster.channel, w)) } channelClusterWrites.POST(/channel-cluster/:channel_type/:channel_id/repair, s.handleChannelClusterRepair)GET .../replicas需要cluster.channel的r读权限POST .../repair需要cluster.channel的w写权限本计划不注册 Leader 显式转移路由留给 P0.6。5.4 错误映射表计划给出了完整的 HTTP 错误映射契约错误HTTP 状态码metadb.ErrInvalidArgument400metadb.ErrNotFound404managementusecase.ErrUnsupportedChannelClusterRepairReason400channel.ErrNoSafeChannelLeader409slotLeaderAuthoritativeReadUnavailable/leaderConsistentReadUnavailable503其他500对应 HTTP 测试场景TestManagerChannelCluster(Operation|Replica|Repair)GET /manager/channel-cluster/2/room-1/replicas返回channel、runtime_reported、commit_seq与每副本reported字段POST /manager/channel-cluster/2/room-1/repair携带{reason:no_leader}返回changed与更新后的channel.leader读路由开启鉴权时要求cluster.channel的r修复路由要求cluster.channel的w非法 channel type → 400未找到 → 404无安全候选 → 409Leader 不可用 → 503。5.5 完整的 HTTP 响应形状来自设计规范GET /manager/channel-cluster/2/room-1/replicas{ channel: { channel_id: room-1, channel_type: 2, slot_id: 9, hash_slot: 123, channel_epoch: 7, leader_epoch: 3, leader: 1, replicas: [1, 2, 3], isr: [1, 2], min_isr: 2, max_message_seq: 42, status: active, features: 0, lease_until_ms: 0 }, runtime_reported: true, commit_seq: 42, min_available_seq: 1, retention_through_seq: 0, replicas: [ { node_id: 1, role: leader, is_leader: true, in_isr: true, reported: true, commit_seq: 42, leo: null, checkpoint_hw: null, lag: 0 }, { node_id: 2, role: follower, is_leader: false, in_isr: true, reported: false, commit_seq: null, leo: null, checkpoint_hw: null, lag: null } ] }注意该示例的精髓Leader 节点reportedtrue且有数值follower 节点reportedfalsecommit_seq/leo/checkpoint_hw/lag全部为null——这就是真实详情的 HTTP 化表达。POST /manager/channel-cluster/2/room-1/repair请求体{ reason: no_leader }响应体修复成功Leader 从 1 变为 2LeaderEpoch 从 3 变为 4{ changed: true, channel: { channel_id: room-1, channel_type: 2, slot_id: 9, hash_slot: 123, channel_epoch: 7, leader_epoch: 4, leader: 2, replicas: [1, 2, 3], isr: [2, 3], min_isr: 2, max_message_seq: 42, status: active, features: 0, lease_until_ms: 1780000000000 } }6. Task 4从internal/app接线app 层负责把窄端口接到既有的本地对象上不创建任何新的全局服务。6.1 状态读取适配器type managerChannelReplicaStatusReader struct { channelLog interface { Status(channel.ChannelID) (channel.ChannelRuntimeStatus, error) } } func (r managerChannelReplicaStatusReader) ChannelRuntimeStatus(ctx context.Context, id channel.ChannelID) (channel.ChannelRuntimeStatus, error) { if r.channelLog nil { return channel.ChannelRuntimeStatus{}, channel.ErrInvalidConfig } return r.channelLog.Status(id) }测试要点状态适配器把app.channelLog.Status结果作为channel.ChannelRuntimeStatus返回channel.ErrNotReady穿透不包装。6.2 修复适配器type managerChannelLeaderRepairOperator struct { repairer runtimechannelmeta.Repairer // 或 AuthoritativeRepairer 兼容接口 }修复适配器调用既有runtime/channelmeta的AuthoritativeRepairer/repairer返回变更后的 meta。计划还给出一个边界优化建议如果调用的是RepairIfNeeded则 usecase 可以直接传 meta 与 reason 而非仅请求形状具体取决于边界是否更清晰保持具体接线留在 app 层。6.3 注入 Options在internal/app/build.go创建managementusecase.New时注入ChannelReplicaStatus: managerChannelReplicaStatusReader{channelLog: app.channelLog}, ChannelLeaderRepair: managerChannelLeaderRepairOperator{repairer: channelLeaderRepairer},接线测试覆盖manager 启用时 management app 收到非 nil 的 channel cluster 操作设计规范 Testing 节。7. Task 5前端 API 契约7.1 TypeScript DTO在web/src/lib/manager-api.types.ts增加export type ManagerChannelClusterReplicaStatus { node_id: number role: string is_leader: boolean in_isr: boolean reported: boolean commit_seq?: number | null leo?: number | null checkpoint_hw?: number | null lag?: number | null } export type ManagerChannelClusterReplicaDetailResponse { channel: ManagerChannelRuntimeMetaDetailResponse runtime_reported: boolean commit_seq?: number | null min_available_seq?: number | null retention_through_seq?: number | null replicas: ManagerChannelClusterReplicaStatus[] } export type RepairChannelClusterLeaderInput { reason?: string } export type ManagerChannelClusterRepairResponse { changed: boolean channel: ManagerChannelRuntimeMetaDetailResponse }7.2 API 包装函数在web/src/lib/manager-api.ts增加export function getChannelClusterReplicas(channelType: number, channelId: string) { return jsonManagerFetchManagerChannelClusterReplicaDetailResponse( /manager/channel-cluster/${channelType}/${encodeURIComponent(channelId)}/replicas, ) } export function repairChannelClusterLeader( channelType: number, channelId: string, input: RepairChannelClusterLeaderInput {}, ) { return jsonManagerFetchManagerChannelClusterRepairResponse( /manager/channel-cluster/${channelType}/${encodeURIComponent(channelId)}/repair, { method: POST, body: JSON.stringify(input) }, ) }注意channelId必须经过encodeURIComponent防止含特殊字符的频道 ID 破坏路径。7.3 客户端测试断言await getChannelClusterReplicas(2, room-1) // fetch called with /manager/channel-cluster/2/room-1/replicas await repairChannelClusterLeader(2, room-1, { reason: no_leader }) // fetch called with method POST, JSON body { reason: no_leader }同时断言ManagerApiError能把修复接口的 409 正确映射为错误对象。8. Task 6unhealthy 页面的详情与修复交互8.1 详情面板状态在web/src/pages/channel-cluster/unhealthy/page.tsx增加局部状态type DetailState { channel: ManagerChannelClusterUnhealthyItem | null detail: ManagerChannelClusterReplicaDetailResponse | null loading: boolean error: Error | null }UI 使用表格下方的内联SectionCard或既有DetailSheet保持简单。8.2 检查副本动作每一行新增按钮Button onClick{() void loadReplicaDetail(channel)} sizesm variantoutline {intl.formatMessage({ id: channelCluster.unhealthy.inspectReplicas })} /Button详情面板展示channel ID/type、slot、leader、ISR、min ISR若runtime_reported则展示运行时 commit 序列每副本一行展示Reported/Not reported未知数值一律渲染为-。8.3 修复 Leader 动作只对 no_leader 行function canRepairLeader(channel: ManagerChannelClusterUnhealthyItem) { return channel.reasons.includes(no_leader) }点击后调用repairChannelClusterLeader(channel.channel_type, channel.channel_id, { reason: no_leader })用返回的changed与channel.leader展示结果文案调用loadFirstPage(true)刷新异常列表第一页。只含isr_insufficient的行不显示修复按钮修复 409 时展示无安全候选这类非破坏性冲突文案并保留该行可见详情 503 在面板中映射为不可用状态。8.4 新增 i18n 文案键计划要求同时在web/src/i18n/messages/en.ts与zh-CN.ts增加以下键channelCluster.unhealthy.inspectReplicaschannelCluster.unhealthy.repairLeaderchannelCluster.unhealthy.repairSuccessChangedchannelCluster.unhealthy.repairSuccessUnchangedchannelCluster.unhealthy.repairConflictchannelCluster.replicaDetail.titlechannelCluster.replicaDetail.runtimeReportedchannelCluster.replicaDetail.runtimeUnreportedchannelCluster.replicaDetail.reportedchannelCluster.replicaDetail.notReportedchannelCluster.replicaDetail.commitSeqchannelCluster.replicaDetail.lag8.5 页面测试矩阵场景断言点击Inspect replicas加载并展示详情Runtime reported、Node 1/leader/Reported/commit 42/lag 0、Node 2/follower/Not reported/-行含no_leader显示Repair leader仅含isr_insufficient的行不显示修复成功以{ reason: no_leader }调用 API展示 changed/leader 文案并重载第一页修复 409展示No safe leader candidate冲突文案且行保持可见详情 503详情面板映射为不可用状态9.
