# Phase 03 Plan 03: Cluster Deploy Orchestration Summary

完整实现 `dm-installer cluster deploy --config <toml>` 端到端命令，将 Plan 01（配置层）和 Plan 02（SSH + preflight + health）整合为六步编排流程，闭合 Phase 3 垂直切片。

## What Was Built

### Task 1: CLI cluster deploy 子命令 + main.rs dispatch
- `src/cli.rs` 新增 `Commands::Cluster(ClusterArgs)` variant，嵌套 `ClusterSubcommand::Deploy(ClusterDeployArgs)`
- `ClusterDeployArgs` 含必填 `--config` PathBuf（无 Option，per D-05）
- `src/main.rs` 新增 dispatch 分支调用 `cluster::run(deploy_args).await`
- `Cargo.toml` dev-dependencies 新增 `tracing-test = "0.2"`
- 3 个新 CLI 测试：test_cluster_deploy_args_config, test_cluster_deploy_requires_config, test_cluster_requires_subcommand

### Task 2: src/cluster/deploy.rs — 7 个节点级编排函数
- `build_dminit_args`: dminit 参数列表，等号两侧无空格（Pitfall 2 防范）
- `upload_installer_and_install`: XML 生成 + SFTP 推 XML + SFTP 推 ISO + 远端 DMInstall.bin -q（CLUS-01 强制步骤，BLOCKER 3 修复）
- `run_dminit_remote`: 远端执行 dminit 初始化
- `distribute_configs`: SFTP 推送 4 个 INI 文件 + 合并 dm.ini
- `start_dmserver_mount`: nohup + mount 模式启动（Pitfall 4 + RESEARCH Q3 nohup 方案）
- `configure_database_role`: disql stdin pipe 执行主/备 SQL（SP_SET_OGUID + ALTER DATABASE）
- `start_dmwatcher`: nohup 启动 dmwatcher

`src/cluster/ssh.rs` MockRunner 扩展：
- 新增 `exec_log()` 和 `sftp_log()` 访问器
- 新增 `strict` 模式（`new_strict()`），保留非严格模式（未匹配返回 Ok）用于 deploy 测试

`src/install/silent_install.rs`: `generate_install_xml` 从 `pub(crate)` 改为 `pub`。

5 个 deploy 单元测试，全部使用 MockRunner 注入。

### Task 3: cluster::run 顶层编排器（替换 Plan 01 unimplemented stub）

`pub async fn run(args: &ClusterDeployArgs) -> Result<()>` 实际实现（签名与 Plan 01 stub 不同，Plan 01 stub 无参数）。

`pub async fn run_with_runners(config, runners, health_check_fn)` 可注入健康检查，六步序列：
1. run_preflight: preflight_all_nodes，任一失败即 bail（D-08）
2. run_install_phase: 并发 upload_installer_and_install + run_dminit_remote
3. run_distribute_phase: 并发 distribute_configs
4. run_startup_phase: 有序启动——primary mount → health_check → primary disql → standby mount → health_check → standby disql（CLUS-02 SC3）
5. run_watcher_phase: 并发 start_dmwatcher

3 个集成测试：
- `test_run_rejects_no_primary_fixture`: 读 tests/fixtures/cluster_invalid_no_primary.toml，断言 Err 含 "primary"
- `test_run_aborts_on_preflight_failure_before_install`: 预检查失败后 exec_log 不含 dminit/dmserver/disql（D-08）
- `test_run_orders_primary_health_before_standby_start`: 使用 `#[tracing_test::traced_test]` + `logs_assert` 验证"主节点就绪"日志早于"启动达梦备实例"（CLUS-02 SC3）

### Task 4: Manual Checkpoint
**状态: manual-deferred** — 无真实双节点测试环境。所有自动化单元测试（79 个）全部通过，编译通过，CLI --help 输出正确，缺 --config 报 required 错误。

## Actual Function Signatures

```rust
// src/cluster/mod.rs
pub async fn run(args: &crate::cli::ClusterDeployArgs) -> Result<()>

pub async fn run_with_runners(
    config: ClusterConfig,
    runners: Vec<(NodeConfig, Arc<dyn ssh::CommandRunner>)>,
    health_check_fn: impl Fn(String, u16, u64) -> Pin<Box<dyn Future<Output=Result<()>> + Send>> + Send + Sync,
) -> Result<()>
```

```rust
// src/cluster/deploy.rs
pub fn build_dminit_args(node: &NodeConfig) -> Vec<String>
pub async fn upload_installer_and_install(node, package_path, runner) -> Result<()>
pub async fn run_dminit_remote(node, runner) -> Result<()>
pub async fn distribute_configs(node, all_nodes, oguid, runner) -> Result<()>
pub async fn start_dmserver_mount(node, runner) -> Result<()>
pub async fn configure_database_role(node, role, oguid, runner) -> Result<()>
pub async fn start_dmwatcher(node, runner) -> Result<()>
```

```rust
// src/cluster/ssh.rs MockRunner
pub fn exec_log(&self) -> Vec<String>
pub fn sftp_log(&self) -> Vec<(String, Vec<u8>)>
pub fn new_strict(responses) -> Self   // 未匹配命令返回 exit 127 Err
pub fn new(responses) -> Self          // 未匹配命令返回 Ok([], 0)（非严格）
```

## Test Count

| Module | Tests |
|--------|-------|
| Plan 01 (config::cluster) | 9 |
| Plan 02 (ssh + preflight + health) | 10 |
| Plan 03 Task 1 (cli) | 3 new (+ 7 existing) |
| Plan 03 Task 2 (deploy) | 5 |
| Plan 03 Task 3 (cluster::mod) | 3 |
| Others (install, config, ui, download) | remaining |
| **Total** | **79** |

## RESEARCH Open Questions Resolved

- **Q3 (nohup)**: 采用 `nohup ... > /tmp/xxx.log 2>&1 &` 方案，SSH exec 返回后进程持续运行
- **Q1 (disql 参数)**: 采用 `echo "SQL" | disql SYSDBA/SYSDBA@localhost:port` stdin pipe 方式，避免 -e 参数兼容性问题

## Phase 3 Requirements Coverage

| Requirement | Coverage |
|-------------|---------|
| CLUS-01: 端到端安装命令 | CLI 子命令 + 完整 6 步编排 |
| CLUS-02: 有序启动 (SC3) | run_startup_phase 顺序 + tracing 日志验证测试 |
| QUAL-01: 单元测试覆盖 | 79 个测试全部通过 |

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 1 - Bug] MockRunner 未匹配命令行为变更**
- **Found during:** Task 2 测试
- **Issue:** 原 MockRunner 未匹配命令返回 exit 127 Err，但 deploy 测试中许多 exec 命令未预设（merge_cmd 等），导致测试失败
- **Fix:** 新增 `strict` 模式：`new_strict()` 保留原 127 行为，`new()` 未匹配返回 Ok([], 0)；更新原有 ssh 测试使用 `new_strict()`
- **Files modified:** src/cluster/ssh.rs
- **Commit:** b671b46

**2. [Rule 2 - Missing Functionality] generate_install_xml 可见性**
- **Found during:** Task 2，deploy.rs 需跨模块调用
- **Fix:** `pub(crate)` 改为 `pub`（最小改动，向后兼容）
- **Files modified:** src/install/silent_install.rs
- **Commit:** b671b46

**3. [Rule 1 - Bug] 测试中 installer_package 路径不存在**
- **Found during:** Task 3 测试
- **Fix:** 使用 `tempfile::NamedTempFile::new()` 创建临时文件作为 fake ISO
- **Files modified:** src/cluster/mod.rs (tests)
- **Commit:** 3d96637

## Known Stubs

无 — 所有函数均有实际实现，无 TODO/placeholder。Task 4 manual checkpoint 标记为 manual-deferred 是测试环境限制，非代码 stub。
