-2. 并发任务处理： -```rust -// 使用信号量和数据共享 -let semaphore = Arc::new(Semaphore::new(MAX_CONCURRENT)); -let view = self.clone(); // 一次克隆，多处使用 -for node_id in nodes { - let permit = semaphore.clone(); - let view = view.clone(); // View 在任务间共享 - tokio::spawn(async move { ... }); -} -``` - -### 7.3 变量类型难分辨的情况 - -#### 7.3.1 Proto生成的Rust类型 -1. proto中的普通字段在Rust中的表现: - - proto中的 `string file_name_opt = 1` 生成的是普通 `String` 类型，而不是 `Option` - - proto中的 `bool is_dir_opt = 2` 生成的是普通 `bool` 类型，而不是 `Option` - - 字段名带 `_opt` 后缀不代表它在Rust中是 `Option` 类型 - -2. proto中的message嵌套在Rust中的表现: - - `DataItem` 中的 `oneof data_item_dispatch` 在Rust中是一个字段 - - 访问路径是: `data.data_item_dispatch` 而不是 `data.data.data_item_dispatch` - - `Option` 需要先 `unwrap()` 才能访问其内部字段 - -#### 7.3.2 容易混淆的类型转换 -1. proto生成的类型和标准库类型的关系: - - proto生成的 `String` 字段不能直接用 `unwrap_or_default()` - - proto生成的 `bool` 字段不能直接用 `unwrap_or()` - -### 7.5 思维方式原则 -- 思维优先于行动： -

修改计划： + 1. 在 call_batch_data（或相应写入数据逻辑）中，对每个数据块的处理循环增加两路并行任务： + - primary_task：调用现有的 rpc_call_batch_data 发送该块数据； + - cache_task：启动一个新的异步任务，调用缓存节点的 RPC 发送数据； + * 注意：cache_task 不应该只传输单个分片，而是负责传输整个 batch 数据。经过对 BatchManager 的分析，发现 BatchManager 可能自动并行内部任务，因此在外部调用时，对每个缓存节点只启动一个 task 来处理整个 batch 写入。 + 2. 使用 tokio::spawn 或 join_all 同时启动这两个任务，并等待它们完成。 + 3. 整合两个任务的返回结果。若任一任务返回失败，则记录错误日志并提示失败；否则认为整体写入成功。 + 4. 最终，整个写入流程将在原有数据分片基础上，增加了并行的缓存节点数据写入逻辑，保证数据在两边同时写入： + - 对于主数据分片写入任务：保持原有策略，每个分片分别创建一个独立的并行任务； + - 对于缓存节点写入任务：采用 batch 接口传输整块数据，每个缓存节点只启动一个 task 来处理整个 batch 数据。 + - 伪代码： + ```rust + // 主数据分片写入任务：每个分片启动一个独立的任务 + let mut primary_tasks = Vec::new(); + for (i, chunk) in data_bytes.chunks(block_size).enumerate() { + // 构造当前分片请求，保持现有逻辑不变 + let req = build_primary_request(chunk, i); + let primary_task = tokio::spawn(async move { + // 调用 rpc_call_batch_data 发送当前分片数据 + rpc_call_batch_data.call(..., req, ...).await + }); + primary_tasks.push(primary_task); + } + + // 缓存节点写入任务：每个缓存节点只启动一次任务，传输整个 batch 数据 + let mut cache_tasks = Vec::new(); + for cache_node in cache_nodes { + let cache_task = tokio::spawn(async move { + // 调用 rpc_call_cache_data 发送整个 batch 数据给该缓存节点 + rpc_call_cache_data.call(..., full_data, cache_node, ...).await + }); + cache_tasks.push(cache_task); + } + + // 等待所有任务完成 + let primary_results = futures::future::join_all(primary_tasks).await; + let cache_results = futures::future::join_all(cache_tasks).await; + + // 整合结果：如果任一 primary 或 cache 任务失败，则记录错误并返回整体失败；否则返回成功 + if primary_results.iter().any(|res| res.is_err()) || cache_results.iter().any(|res| res.is_err()) { + tracing::error!("数据写入失败"); + return Err(String::from("整体写入失败").into()); + } + ``` + 5. 新问题： + -

pub req_id: ReqId, - pub event_ctx: EventCtx, - pub res: Option, - pub sub_waiters: Vec>, - _dummy_private: (), - } - ``` - -### 1.2 公开特化类型 -- `FnExeCtxAsync` 和 `FnExeCtxSync`: - - 异步执行上下文支持 Jar、Wasm、Native 类型，包含子任务支持和完整的性能监控和日志。 - - 同步执行上下文仅支持 Native 类型，不支持子任务，包含基本的性能监控和日志。 - -### 1.3 类型安全 -- `FnExeCtxAsyncAllowedType` 和 `FnExeCtxSyncAllowedType`: - - 异步允许的类型 (Jar, Wasm, Native) - - 同步允许的类型 (仅 Native) - - 通过 `TryFrom` 在编译时强制类型安全 - -## 2. 实例管理设计 - -### 2.1 实例类型与管理器 -- `Instance` 和 `InstanceManager`: - - `Instance` 包含 Owned、Shared 和 Native 类型。 - - `InstanceManager` 管理应用实例和运行时函数上下文。 - ```rust - pub enum Instance { - Owned(OwnedInstance), - Shared(SharedInstance), - Native(NativeAppInstance), - } - - pub struct InstanceManager { - pub app_instances: SkipMap, - pub instance_running_function: DashMap, - } - ``` - -### 2.2 运行时函数上下文 -- `UnsafeFunctionCtx`: - - 包含 Sync 和 Async 类型，分别对应 `FnExeCtxSync` 和 `FnExeCtxAsync`。 - -## 3. 关键修改记录 - -### 3.1 同步/异步执行流程优化与错误处理增强 -- 简化 `finish_using`，移除不必要的异步版本，统一使用同步实现。 -- 添加同步版本的 `load_instance_sync`，仅支持 Native 类型。 -- 优化 `execute_sync` 中的异步调用处理，统一性能监控和日志记录格式。 -- 添加 `UnsupportedAppType` 错误类型，完善同步执行时的类型检查。 - -## 4. 待办事项 -- [x] 考虑添加同步版本的 `load_instance` -- [ ] 优化 `execute_sync` 中的异步-同步转换 -- [ ] 完善错误处理和日志记录 - -## 5. 核心设计原则 - -### 5.1 基础原则与 View 模式设计规则 -- 同步/异步分离，类型安全，性能监控，资源管理。 -- View 生成： - - View 结构体和 `LogicalModule` trait 的实现由宏生成。 - - 只需实现 `inner_new` 函数，使用 `logical_module_view_impl!` 生成访问函数。 - - 每个需要访问的模块都需要单独的 impl 宏调用。 - -### 5.2 去掉 #[derive(LogicalModule)] 的原因和注意事项 -- 实现特定功能：根据需求在 `DataGeneralView` 中实现特定功能，检查冲突。 -- `inner` 字段的管理：由宏管理，不能直接操作，通过宏生成的接口使用。 -- 错误分析：去掉派生后，仔细分析和解决可能出现的错误。 - -## 6. msg_pack 消息封装 - -### 6.1 基本原则与实现示例 -- 使用 `msg_pack.rs` 中的宏实现 trait，使用 `define_msg_ids!` 管理消息类型。 -- 通过 `RPCReq` trait 定义请求-响应关系。 - ```rust - define_msg_ids!( - (proto::sche::BatchDataRequest, pack, { true }), - (proto::sche::BatchDataResponse, _pack, { true }) - ); - - impl RPCReq for proto::sche::BatchDataRequest { - type Resp = proto::sche::BatchDataResponse; - } - ``` - -### 6.2 最佳实践 -- 新增消息类型时：在 `define_msg_ids!` 中添加定义，实现 `RPCReq` trait。 -- 使用消息时：使用 `RPCCaller` 和 `RPCHandler`，遵循统一的错误处理。 -

View 模式使用规范 -基本原则： -- View 本身已经是完整引用：不需要额外的 view 字段 -- 异步任务中使用：`self.clone()` -- 模块访问：通过 view 直接访问其他模块 - -示例代码： -```rust -// 正确示例 -let view = self.clone(); // View 本身克隆 -let resp = view.data_general().rpc_call_write_once_data... - -// 错误示例 -let view = self.view.clone(); // 错误：不需要额外的 view 字段 -let data_general = self.data_general().clone(); // 错误：不需要单独克隆模块 -``` - -#### 4. 异步任务数据处理检查清单 -- [ ] 是否只克隆必要的数据？ -- [ ] 临时变量是否正确处理？ -- [ ] View 的使用是否符合规范？ -- [ ] 是否避免了重复克隆？ -- [ ] 数据共享策略是否合理？ - -#### 5. 常见场景示例 - -1. 批量数据处理： -```rust -// 正确处理临时变量和部分数据 -let split_info = split_info.clone(); // 临时变量必须克隆 -let data_item = data_item.clone_split_range(range); // 只克隆需要的部分 -let view = self.clone(); // View 克隆用于异步任务 -``` - -2. 并发任务处理： -```rust -// 使用信号量和数据共享 -let semaphore = Arc::new(Semaphore::new(MAX_CONCURRENT)); -let view = self.clone(); // 一次克隆，多处使用 -for node_id in nodes { - let permit = semaphore.clone(); - let view = view.clone(); // View 在任务间共享 - tokio::spawn(async move { ... }); -} -``` - -### 7.3 变量类型难分辨的情况 - -#### 7.3.1 Proto生成的Rust类型 -1. proto中的普通字段在Rust中的表现: - - proto中的 `string file_name_opt = 1` 生成的是普通 `String` 类型，而不是 `Option` - - proto中的 `bool is_dir_opt = 2` 生成的是普通 `bool` 类型，而不是 `Option` - - 字段名带 `_opt` 后缀不代表它在Rust中是 `Option` 类型 - -2. proto中的message嵌套在Rust中的表现: - - `DataItem` 中的 `oneof data_item_dispatch` 在Rust中是一个字段 - - 访问路径是: `data.data_item_dispatch` 而不是 `data.data.data_item_dispatch` - - `Option` 需要先 `unwrap()` 才能访问其内部字段 - -#### 7.3.2 容易混淆的类型转换 -1. proto生成的类型和标准库类型的关系: - - proto生成的 `String` 字段不能直接用 `unwrap_or_default()` - - proto生成的 `bool` 字段不能直接用 `unwrap_or()` - -### 7.5 思维方式原则 -- 思维优先于行动： - - 在开始任何操作前，先理解"为什么"而不是"怎么做" - - 确保完全理解当前上下文中的所有信息 - - 避免机械性思维和跳过思考的行为模式 - -

问题代码：截取导致问题的具体代码片段 - 2. 上下文代码：截取理解问题所需的相关代码 - 3. 问题成因：详细分析问题的具体原因 - 4. 修复方案：说明如何修复以及为什么这样修复 - 5. 修改验证：列出验证修改正确性的方法 - - 分析记录必须： - - 使用代码块格式展示代码 - - 保持代码片段的完整性和可读性 - - 确保分析逻辑清晰 - - 说明修改的影响范围 - -- 父问题相关性分析： - - 在开始分析任何问题之前，必须首先进行父问题相关性分析 - - 分析步骤： - 1. 确认当前问题的父问题是什么 - 2. 回溯父问题的执行计划和记录 - 3. 判断当前问题是否是父问题引起的 - 4. 确认解决当前问题是否必要且有助于解决父问题 - - 分析结果必须包含： - 1. 父问题的明确引用 - 2. 相关性的具体分析 - 3. 解决必要性说明 - 4. 优先级判断 - - 如果当前问题与父问题无关： - 1. 记录分析结果 - 2. 暂时搁置该问题 - 3. 继续专注于父问题的解决 - -- 内化规则： - - 把规则视为思维框架而不是外部约束 - - 养成先检查当前上下文的习惯 - - 避免在已有信息的情况下去外部搜索 -- 关注本质： - - 理解问题的根本原因比立即解决问题更重要 - - 分析失误的思维模式而不是简单记住正确操作 - - 把经验转化为思维方式而不是操作步骤 - -## 8. 代码评审与修改文档规则 - -### 8.1 修改计划与记录要求 -- 每次修改代码前： - 1. 必须查看项目根目录的 `review.md` 文件 - 2. 根据现有内容确定修改计划的位置和层级 - 3. 在对应位置添加修改计划 - 4. 使用 markdown 格式记录，保持层级结构清晰 - -### 8.2 文档结构规范 --

第一个子节点必须是对问题的分析 - 3. 后续子节点是具体的计划任务 - 4. 每个计划任务下可以包含新的问题，遵循相同的结构 - 5. 已完成的任务标记为"已完成" - 6. 保持缩进层级清晰 - -- 示例说明： - ```markdown - - 任务：修复类型转换错误 - - 分析：当前代码在类型转换时未考虑空值情况 - - 计划任务1：添加空值检查 - 新问题：如何处理空值转换失败 - - 分析：需要在转换失败时提供默认值 - - 计划任务：实现 Option 转换 - 已完成 - - - 计划任务2：添加单元测试 - 已完成 - ``` - -### 8.3 记录要求 -1. 修改计划必须包含： - - 修改目的 - - 预期效果 - - 可能的风险 - - 具体步骤 - -2. 修改过程必须记录： - - 实际执行的步骤 - - 遇到的每个问题 - - 解决方案和结果 -

最老未完成任务识别： - - 从上到下扫描所有顶级任务 - - 跳过带有 `（done）` 标记的任务 - - 第一个不带 `（done）` 标记的任务即为最老未完成任务 - - 子任务不影响父任务的完成状态判断 - -4. 任务优先级： - - 未完成任务按出现顺序表示优先级（越靠后优先级越高） - - 子任务优先级高于同级后续任务 - - 阻塞性问题优先级最高 - -#### 8.5.2 任务解析检查清单 -在识别和处理任务时，必须检查： -- [ ] 任务是否有 `（done）` 标记 -- [ ] 任务是否为顶级任务 -- [ ] 是否有未完成的子任务 -- [ ] 任务的位置是否符合顺序规则 -- [ ] 是否存在阻塞性问题 - -## 9. 批量数据接口设计 - -### 9.1 BatchTransfer 设计规范 - -#### 9.1.1 组件职责定义 - -1.

- 精简了 .cursorrules 文件内容 - - -- (done) 任务：完善 write_data 数据分片同时对接缓存节点的并行写入设计 - - 分析：当前需要在数据分片过程中，同时将数据通过两个不同的 RPC 调用分别发送到主存储节点和缓存节点。由于调用的 RPC 不同，需要在同一个数据块处理逻辑中并行启动两个任务，一个调用 rpc_call_batch_data，另一个调用缓存节点的 RPC（例如 rpc_call_cache_data）。两任务并行执行，最终收集各自结果，并综合判断整体成功情况。错误处理部分简化：记录错误日志，失败时返回提示信息，不做过细重试处理。 - - 修改计划： - 1. 在 call_batch_data（或相应写入数据逻辑）中，对每个数据块的处理循环增加两路并行任务： - - primary_task：调用现有的 rpc_call_batch_data 发送该块数据； - - cache_task：启动一个新的异步任务，调用缓存节点的 RPC 发送数据； - * 注意：cache_task 不应该只传输单个分片，而是负责传输整个 batch 数据。经过对 BatchManager 的分析，发现 BatchManager 可能自动并行内部任务，因此在外部调用时，对每个缓存节点只启动一个 task 来处理整个 batch 写入。 - 2. 使用 tokio::spawn 或 join_all 同时启动这两个任务，并等待它们完成。 - 3. 整合两个任务的返回结果。若任一任务返回失败，则记录错误日志并提示失败；否则认为整体写入成功。 - 4. 最终，整个写入流程将在原有数据分片基础上，增加了并行的缓存节点数据写入逻辑，保证数据在两边同时写入： - - 对于主数据分片写入任务：保持原有策略，每个分片分别创建一个独立的并行任务； - - 对于缓存节点写入任务：采用 batch 接口传输整块数据，每个缓存节点只启动一个 task 来处理整个 batch 数据。 - - 伪代码： - ```rust - // 主数据分片写入任务：每个分片启动一个独立的任务 - let mut primary_tasks = Vec::new(); - for (i, chunk) in data_bytes.chunks(block_size).enumerate() { - // 构造当前分片请求，保持现有逻辑不变 - let req = build_primary_request(chunk, i); - let primary_task = tokio::spawn(async move { - // 调用 rpc_call_batch_data 发送当前分片数据 - rpc_call_batch_data.call(..., req, ...).await -
