正确。 +- MySQL、PostgreSQL、SQLite 和 SQL Server 有直接的驱动级对象测试，但对象种类并不对称；PostgreSQL Type、SQL Server trigger/sequence/type 的 DDL/依赖边界仍应补齐。 +- DuckDB、rqlite、Turso 暴露了部分对象命令或共享 SQLite 方言查询，但缺少各自 crate 中的对象树操作测试。跨驱动共享 SQL 生成测试不能替代这些驱动的命令执行测试。 +- ClickHouse、Elasticsearch、HBase、InfluxDB、MongoDB、Vector、VictoriaMetrics 的目录模型并非完整 SQL routine tree；应测试它们实际提供的 database/namespace、table/index/collection/measurement、字段或列元数据和特殊名称/错误处理，而不是机械补齐 SQL Server 对象种类。 + +本矩阵统计的是测试是否存在和覆盖到哪里，不表示缺口等于产品实现必然有 bug，也不以测试文件数量推算百分比。新增 driver 能力、命令或对象类型时，应同步更新对应矩阵格及代表性测试证据；具体新增测试仍放在驱动 crate 内。 diff --git a/docs/development/e2e-testing.md b/docs/development/e2e-testing.md index 33962161f..dab41129c 100644 ---

map、回滚/关闭调用。 +- 断言：淘汰不得在活动事务仍映射时静默关掉物理资源后保留可提交句柄。目标行为是在回收时先在原 resource 回滚并移除/终结事务映射，再关闭资源；回滚结果未知则转 OutcomeUnknown/SessionLost，不重新连接后复用旧 dbSessionId 或在新 resource 提交旧 handle。事务状态不得在物理 session 丢失后继续报告 Active。失败后的显式新 session 使用新 ID，marker 不提交。 +- 基线说明：旧实现应先记录复现证据：`cleanup_idle_connections` 保留 owner map，`get_session` 通过该 map 同 ID 重连，而 `session_transactions` 由命令层单独管理。此用例在连接管理重构完成前可作为已知失败，完成后必须转绿；不可删掉断言或用仅检查 UI 文案替代。 + +## 17. 验收标准与证据 + +| 门槛 | 必须通过的用例 | 必须提交的证据 | +| --- | --- | --- | +| 类型/身份/目标 | CM-01～07 | 类型与 schema 测试、越权入口矩阵 | +| 会话正确性 | CM-08～19 |

编译期注册。原生同进程驱动属于可信代码。管理员升级发布包/镜像，worker drain 后切换；独立 driver runner 是后续隔离方案，需版本化 RPC，不能把 Rust trait 当作稳定动态 ABI。 + +## 9. 多实例部署与故障 + +固定 session 路由到持有真实资源的 worker；客户端无需知道 worker。请求附带 runtimeEpoch/dbSessionId。owner 失效返回 SessionLost，不在其他 worker 上复用旧 session ID。替代会话得到新 ID，旧事务和临时状态不能恢复。 + +Job 使用持久化租约和执行 epoch。旧 worker 失去续约后停止派发；fencing token

dbSessionId、attachmentToken、取消句柄或数据库凭据。Web 部署使用独立受限 origin 与 sandbox/CSP；Wapp 不能从 iframe 自行取得用户 cookie 或调用任意服务端 URL。用户身份与每次操作授权由父应用和服务端重新验证，卸载/撤权即关闭桥接订阅。 + +特权 EP 是桌面 host 内的可信扩展，Web server 不加载 native EP，也不把 EP 包下发到浏览器执行。团队版若需要同等功能，必须走显式授权的服务 API。Theme 只分发 schema 校验后的静态资源，Web CSP 禁止脚本执行；主题不能调用 backend 或访问 secret。Driver/Workspace App/EP/Theme 的扩展面相互独立。 + +## 10. 安全和环境差异 + +团队共享 profile 不共享

— it is not evidence that a write rolled back — and require partial or unknown for pipelineAborted - separate RequestError from post-dispatch failures: only rejected requests raise ApiError; dispatched-but-failed executions surface as ExecutionState='failed' plus ExecutionErrorCode - add createProfile to IdempotentOperation, bound to identity and organization but not to a session epoch; state that startJob is likewise not owner-bound - widen the package inventory in system-overview to mark what already exists versus what this design creates --- docs/README.md | 2 +-

`packages/driver-api/src/traits.rs` 的默认实现里，`has_schema_level` = `false`（:123）、`has_multi_database` = `false`（:133）、`default_schema` = `None`（:147）、`ddl_atomicity` = `DdlAtomicity::Unknown`（:157）、`begin_transaction`/`commit`/`rollback` 返回 `TransactionError`（:602/:743/:749）、`begin_read_snapshot` 返回 `Unsupported("stable read snapshots are not supported by this driver")`（:734）、`discard_connection` 返回 `Unsupported`（:653）、`cancel_query_with_execution` 返回 `Unsupported("precise query cancellation is not supported for execution {}")`（:794）。**唯一破坏 fail-closed 的是 `cancel_query`**：它没有默认体，是必实现方法，而 15 个 path 驱动里有 13 个把它实现成 `Ok(())`。这是 P2 退出门槛「新增能力缺失不会 no-op 成功」最直接的违反点，见 [§7](#7-unsupported-的拒绝断言要求)。 + +**事实二：当前没有任何驱动拥有一等固定资源会话。** 逐个读 `connect` 得到的连接模型是： + +- postgres：`sqlx` 连接池按 handle 建，每库一个池（`MAX_DATABASE_POOLS_PER_HANDLE = 8`，`DATABASE_POOL_MAX_CONNECTIONS = 2`），外加一个独立的 `control_pool`（max 1 / min 0）供取消用；每次操作 `pool.acquire()`。 +- mysql：池化，且**每条语句执行前**都要对刚 acquire 到的连接重跑 `apply_active_database`。 +- sqlserver：每个 `pool_id` 恰好一个 `tiberius::Client`，`handle.id == handle.pool_id`，是真实物理 TCP 会话。 +- sqlite：`SqlitePoolOptions::max_connections(1).min_connections(1)`，单文件。 +- duckdb：`::duckdb::Connection` 包在 `Arc>` 里，一个 handle 一个。 +- redis：handle 存一条 `RedisConn { plan, live }`；**大多数面向库的操作直接在这条常驻连接上发 `SELECT` 再执行**（`with_live_op!` / `with_live_op_topo!`，见 `mod.rs:33-64`，调用点如 `mod.rs:208`、`:242`、`:264`、`:357`、`:387`），只有元数据读取另开一次性连接（`open_pinned_conn`：`database.rs:122` 的 `get_tables`、`database.rs:146` 的 `get_table_schema`；`mod.rs:313-316` 的全库 `DBSIZE` 统计也另开 `open_live_conn`），以免扰动共享会话。因此「切换 db」在同一驱动里**就地切换与换连接两种机制并存**，矩阵取值待 P0 定案（[§9](#9-待-p0-验证清单) 第 7 条）。 +- 其余 9 个（mongodb、clickhouse、rqlite、turso、elasticsearch、hbase、influxdb、victoriametrics、vector）：存 `(client, base)` 元组，**完全无会话**。 + +事务只在事务存续期间临时占用一条连接（postgres 是 `pool.acquire()` 后把 `PoolConnection` 存进 `self.transactions`；mysql 同理；sqlite 通过 `tx.connection_id` 重建 handle；sqlserver 直接就是那条常驻 client）。所以**不能**把任何驱动标成 `statefulSession: supported`。sqlserver / duckdb / redis 三格写 `unknown` 而不是 `unsupported`，是因为它们确实存在「物理连接在 handle 生命周期内不变」的事实，只是没有任何声明或校验机制把它变成可依赖的保证——见 [§6.1](#61-允许与禁止)。 + +**事实三：`unsupported` 的驱动大多不是「不支持」，而是「根本没接」。** 8 个驱动（duckdb、elasticsearch、hbase、influxdb、rqlite、turso、vector、victoriametrics）**一个能力方法都没覆盖**，全走 trait 默认。这在 P2 里要分两种处理：真正没有该能力的（HTTP 文档库的 `snapshots`、`transactions`）保留 `unsupported` 并补拒绝断言；引擎支持但驱动没接的（SQLite 快照、DuckDB 事务、Redis 事务）要进批次 1/2 补实现，否则 Host 会把「驱动没接」和「后端不支持」混成同一个错误，无法给出可执行的下一步。 + +## 3. 分驱动说明 + +每节只写已读代码能证明的语义；与连接管理 §5.1 的 9 个契约操作（`describeResource` / `acquireResource` / `executeOnResource` / `observeSession` / `changeContext` / `begin|commit|rollback` / `requestCancel` / `resetResource` / `closeResource）逐条的差距在每节末尾的「与目标契约的差距」中给出。 + +### 3.1 PostgreSQL（含 questdb / cloudberry 复用） + +`packages/drivers/postgres` 一个 crate 注册 3 个 factory：`PostgresFactory`（`driver_id = "postgresql"`）、`QuestDbFactory`（`"questdb"`）、`CloudberryFactory`（`"cloudberry"`）。后两个的 `create()` 返回 `ReuseDriver::new_with_precise_cancel(PostgresDriver, "questdb"|"cloudberry", true)`。三个 factory 的 `supports_explain()` 与 `supports_query_execution_cancel()` **都**返回 `true`（`lib.rs:36,42` / `:60,66` / `:86,92`），但 `supports_cancel_query()` **只有 `postgresql` 返回 `true`**（`lib.rs:39`），`questdb` / `cloudberry` 返回 `false`（`:63` / `:89`）。 + +- **多库/多 schema**：库级由多池承担，每库一个池，单 handle 最多 8 个；schema 级由 `search_path` 承担。`build_pg_options()` 在**建连时**写入 `.database(resolve_connect_database(config))`，并且只在 `config.schema` 非空时追加 `opts.options([("search_path", format!("\"{clean}\",public"))])`。`fetch_tables_from_pool` 读取时也固定补 `'public'`。这意味着 schema 是**连接建立时固化**的，驱动里没有对活会话发 `SET search_path` 的路径。 +- **事务隔离**：`begin_transaction_impl` 为每个 `handle.id` 记一条事务，从该 handle 自己的池里 `pool.acquire()` 一条专用连接执行 `BEGIN`，并把这条连接存进 `self.transactions`。源码注释明确写：事务占用本库池中的一条连接，指向另一个库的语句被拒绝，绝不静默重定向。`begin_read_snapshot_impl` 发 `BEGIN ISOLATION LEVEL REPEATABLE READ READ ONLY`。 +- **会话作用域句柄**：`prepare_query_execution` 存在，但 `QueryExecutionId` 在 API 文档里被要求保持 opaque，禁止暴露后端 PID/线程号。 +- **取消**：`cancel_query` 返回 `Err(DriverError::Unsupported("legacy session-wide query cancellation is disabled; use an execution handle"))`；`cancel_query_with_execution` 走独立的 `control_pool`。这是 15 个驱动里**两个**正确拒绝 legacy cancel 的之一。 +- **重置/丢弃**：`discard_connection` 未覆盖，走 trait 默认 `Err(Unsupported(...))`（fail-closed）。 +- **多库标识**：`is_active_database` 是只读元数据查询，源码注释写明它**从不被改成用来切换会话**；`close_database_pool` 拒绝关闭 handle 自己的库。 + +**与目标契约的差距**：`changeContext` 必须返回 `RequiresReplacement` 而不是 `Unsupported`——库与 schema 都能换，只是要换一条连接，这是 `requiresReplacement` 的教科书场景。`resetResource` 目前只能整体丢弃（且本驱动连 `discard_connection` 都没实现），要补一个「回滚未决事务 + 恢复 `search_path` 到 baseline」的实现才能给 `resetForReuse: verified`。`executeOnResource` 要求的「不自行再从随机 pool 取连接」目前不成立：`begin_transaction` 之外的路径都是每次 `pool.acquire()`。 + +### 3.2 MySQL（含 mariadb / doris / starrocks / manticore / ob_oracle 复用） + +`packages/drivers/mysql` 一个 crate 注册 **6 个 factory**：`mysql`、`mariadb`、`doris`、`starrocks`、`manticore`、`ob_oracle`（驱动 id 用的是下划线，见 `lib.rs:142`），全部 `supports_query_execution_cancel() -> true`。 + +- **切库语义（本矩阵里唯一的 `namespaceSwitch: inPlace`）**：`apply_active_database(handle, &mut conn)` 在**每条语句执行前**对新 acquire 到的连接执行 `USE \`db\``（`build_use_database_sql` 做标识符引用，拒绝空名与含 NUL 的名字），随后调用 `conn.clear_cached_statements()`——因为 MySQL 在 PREPARE 时就解析非限定名，不清缓存会打到错的库。这条路径的定义在 `connection.rs:130`（内部经 `execute_use_on_conn`，在 `connection.rs:103` 清 sqlx 语句缓存），在 `mysql.rs` 里有 9 个调用点（`1300`、`1410`、`1509`、`1603`、`1654`、`1680`、`1708`、`1740`、`1816`），另有一处在 `execution.rs:159`，结论是：**MySQL 的库上下文是每操作重放的，不是会话粘滞的**。 +- **上下文观察**：`current_database_on_conn` 用**文本协议**发 `SELECT DATABASE()`，源码注释解释：走 prepared 会返回 PREPARE 时刻的 schema，因此必须文本协议。 +- **协议限制**：`execute_text_on_conn` 注释记录 MySQL 会在 prepared 协议上拒绝 `BEGIN`/`COMMIT`/`ROLLBACK`/`USE`/`SET`/DDL/`CREATE PROCEDURE`，错误码 1295 (HY000)。`execute_use_on_conn` 因此固定走文本路径。 +- **事务隔离**：`begin_transaction` 先 `apply_active_database` 再 `BEGIN`；`begin_read_snapshot` 发 `SET TRANSACTION ISOLATION LEVEL REPEATABLE READ` + `START TRANSACTION WITH CONSISTENT SNAPSHOT, READ ONLY`，且**失败时关闭该连接**，避免一次性隔离级别泄漏。 +- **DDL 原子性**：`ddl_atomicity` = `DdlAtomicity::AutoCommitPerStatement`，与 PostgreSQL 的 `Transactional` 正好构成一对，宿主据此决定 schema-diff 部署是否包事务。 +- **取消**：`cancel_query` 返回 `Err(DriverError::Unsupported(...))`（与 postgres 同文案）；`cancel_query_with_execution` 锁住注册表条目直到 `KILL QUERY ` 完成，并处理了 thread id 在过早清理后被复用的风险；`cleanup_query_execution` 直接移除注册表条目（`execution.rs:25-38`），`execution.cancel_requested` 的复位则发生在 `cancel_query_with_execution` 的各条失败分支。这是 15 个驱动里**第二个**正确拒绝 legacy cancel 的。 +- **重置/丢弃**：`discard_connection` 未覆盖，走默认 `Err(Unsupported(...))`。 + +**与目标契约的差距**：`inPlace` 只在「同一个活连接上」成立，而 `executeOnResource` 每次都可能拿到池里另一条连接。P2 要么让 `changeContext` 在 MySQL 上也返回 `requiresReplacement`（并把 `inPlace` 收窄到「同一 `ResourceHandle` 已固定的那条连接」），要么引入显式的资源固定。这一取舍必须在 P0 定案并写进契约测试，不能靠 `apply_active_database` 的存在就宣称 `inPlace` 成立。 + +### 3.3 SQLite + +- **连接模型**：`SqlitePoolOptions::max_connections(1).min_connections(1)` 建在 `sqlite:{path}` 上，随后 `PRAGMA journal_mode=WAL`；`ConnectionHandle` 的 `id` 与 `pool_id` 取同一个值。 +- **库即文件**：`get_databases` 恒返回 `vec!["main"]`。`physical_database_identity` 读 `PRAGMA database_list` 的 `file` 列得到 `sqlite_file_identity`。迁移路径里出现过 `ATTACH DATABASE '...' AS aux` 与 `"aux".sqlite_master` 限定名，但**该 `ATTACH` 只出现在 `#[cfg(test)]`**（`sqlite.rs:1177`），生产路径没有跨文件附加。因此矩阵里是「引擎能力存在，驱动不支持」。 +- **DDL 原子性**：`DdlAtomicity::Transactional`。 +- **事务**：`begin_transaction` 走 `execute(handle, "BEGIN")`，产出 `TransactionHandle { id: "sqlite_tx_", connection_id: handle.id }`；`commit`/`rollback` 由 `tx.connection_id` 重建 `ConnectionHandle` 后续行，源码注释说明这就是因为 `connect()` 让 `handle.id` 与 `handle.pool_id` 取了同值。 +- **未覆盖的方法**：`begin_read_snapshot`、`prepare_query_execution`、`discard_connection` 均未覆盖，分别落到 trait 默认的 `Unsupported`（fail-closed）。 +- **取消**：`cancel_query` 只打一条 `tracing::debug!("sqlite: cancel_query is a no-op (single-connection, in-process)")` 然后返回 `Ok(())`。 + +**与目标契约的差距**：池大小为 1 是本文档最需要守住的一条红线。连接管理 §5.2 明确写「不能因为『池大小为 1』就声明固定会话：底层重建和不同 consumer 仍会破坏语义」。SQLite 的 `max_connections(1)` 完全符合这个反例——底层仍然是 sqlx pool，`handle` 仍然可以被 `disconnect` 之外的路径重建，Host 侧也没有任何基线校验。因此 `statefulSession` 必须保持 `unsupported`。`preciseCancel` 应从现在的「no-op 成功」改为显式 `Unsupported`（见 §7）。 + +### 3.4 SQL Server + +- **连接模型**：`connect_client` 直接用 `TcpStream` + `tiberius::Client::connect`（超时包裹），不走 SQLx。`connect` 每个 `pool_id` 保存**恰好一个** `Client`，`handle.id == handle.pool_id`。 +- **命名空间**：对象名一律全限定 `[db].[dbo].[obj]`。单测（`sqlserver.rs:2086`）显式断言没有任何读路径内嵌 `USE [`，并断言空库名时 SQL 保持本地。注释还记录了 T-SQL 没有 `LIMIT`、分页必须写 `OFFSET … ROWS FETCH NEXT … ROWS ONLY` 因而强制 `ORDER BY`。因此**驱动从不发 `USE`**，切库是寻址问题不是会话问题，`namespaceSwitch` 是 `unsupported`（就当前实现而言）。 +- **会话级开关**：`explicit_identity_insert_requires_session_toggle` = `true`，`set_identity_insert` 的作用域是物理 SQL Server 会话——这是矩阵之外的一个真实会话级副作用，P0 需要决定它归入 `sessionScopedHandles` 还是 `initializationRequirements`。 +- **事务**：`begin_transaction` 先 `ensure_no_open_transaction` 再 `BEGIN TRANSACTION`，失败时移除 client；`begin_read_snapshot` 读取并保存当前隔离级别（`restore_isolation`）；`commit`/`rollback` 校验 `tx.connection_id` 匹配后执行，必要时附 `SET TRANSACTION ISOLATION LEVEL {level}` 复原，**执行失败即 `clients.remove()`**（fail-closed 丢弃）。 +- **丢弃**：`discard_connection` 是 15 个驱动里**唯一**实现了的：移除事务条目 + 丢弃 client，返回 `Ok`。 +- **取消**：`cancel_query` 返回 `Ok(())` 空实现，且没有覆盖 `cancel_query_with_execution` / `supports_query_execution_cancel`（即默认 `false` + 默认 `Err(Unsupported(...))`）。这是最刺眼的一格：**`preciseCancel` 明确 `unsupported`，而 legacy cancel 却静默「成功」**。 +- **DDL 原子性**：未覆盖 → `DdlAtomicity::Unknown`。 +- **绑定参数**：`max_bound_parameters` = 2100。 +- **测试基座**：`tests/` 下共 9 个 `.rs`——7 个 `live_*.rs`（`live_admin_and_sync`、`live_connection`、`live_pagination`、`live_query_types`、`live_schema_metadata`、`live_streaming`、`live_write_and_ddl`）+ `sync_adapter_smoke.rs` + `command_definitions.rs`，另有 `common/` 辅助模块。它是当前 15 个 path 驱动里真实服务端测试覆盖最厚的。 + +**与目标契约的差距**：这是最接近目标资源模型、也最需要谨慎的一个驱动。它有真实的单物理会话，有 `discard_connection`，有会话级开关，但**没有声明、没有基线校验、没有 reset 复原**。`resetForReuse` 的枚举只有 `verified` / `unsupported` 两值，本驱动拿不到 `verified`——`discard` 是丢弃不是复原。P2 的工作是把「回滚未决事务 → 复原 `restore_isolation` → 复原 `SHOWPLAN_TEXT`/IDENTITY_INSERT 等会话开关」做成显式 `resetResource`，再由 CM-26/CM-69 验证之后才能填 `verified`。 + +### 3.5 Redis + +- **库即 db index**：`get_databases` 读 `CONFIG GET databases`（失败回退 16），返回 `(0..db_count).map(|i| format!("db{i}"))`。 +- **切库**：`parse_db_name` 去掉可选的 `db` 前缀后 `u32::parse`，空串或不可解析直接 `DriverError::QueryFailed("invalid database name (expected e.g. db0)")`；`open_pinned_conn` 克隆 handle 的 plan，**重开**一条 `open_live_conn(&plan)`，再 `select_db(&mut live, db_index)`——这条路径用于元数据枚举，`mod.rs:140-146` 的注释写明这样做是为了让浏览某个 db 不会改动共享会话。但同一个驱动在 `with_live_op!` / `with_live_op_topo!` 里对常驻 `rc.live` 直接 `select_db`（`mod.rs:208`、`:242`、`:264`、`:357`、`:387`），即**就地切换**。两种机制并存，所以本文既不记 `inPlace` 也不记 `requiresReplacement`，改记「待 P0 验证」（[§9](#9-待-p0-验证清单) 第 7 条）。 +- **单测**：`get_table_schema_rejects_unparsable_database` 覆盖了拒绝路径。 +- **事务**：三个事务方法都未覆盖，走 trait 默认 `TransactionError`。注意 `ops/value_search.rs:264` 有一个 `commit`，它是任务/作业累计器（把完成的批次折进任务总数，单测 `commit_accumulates_until_task_replaced`），**不是数据库事务**，不要在迁移时误当成事务实现。 +- **取消**：`cancel_query` 返回 `Ok(())`。 +- **依赖**：`redis 0.27`（tokio-comp / aio / cluster-async / sentinel / tls）、`rmpv`、`flate2`、`urlencoding`、`futures-util`，可选 `tauri 2`；不依赖 `http-support`。 + +**与目标契约的差距**：`contextObservation` 与 `namespaceSwitch` 两格待 P0 验证（[§9](#9-待-p0-验证清单) 第 1、7 条）。`statefulSession` 写 `unknown` 是因为 handle 里确实常驻一条 `live` 连接（面向库的操作就在它上面发 `SELECT`），但没有任何声明或校验机制把「句柄生命周期内连接不变」变成可依赖的保证；P0 需要用 CM-09 判定这条常驻连接在并发下是否可被复用为固定资源。 + +### 3.6 MongoDB + +- `connect` 存 `(client, config.database)`；`get_databases` 调 `client.list_database_names()`。 +- `has_multi_database` = `true`；`driver_category` = `DriverCategory::Document`（15 个 path 驱动里只有它与 redis 显式声明分类：`Document` 与 `KeyValue`，其余 13 个走默认 `Sql`；git 驱动 kiwi / superset 另显式声明为 `Sql`）。 +- `get_tables` 注释写明 MongoDB 没有 schema 层、**database 就是命名空间**，随后 `validate_schema_target(self, database, schema, SchemaScope::AnySchema)` 再 `client.database(database).list_collection_names()`。 +- 寻址方式是 `client.database(name)`——**每次操作按名寻址，没有会话**。 + +**与目标契约的差距**：`namespaceSwitch` 待 P0 验证（[§9](#9-待-p0-验证清单) 第 2 条）。根因是 §5.2 的 `namespaceSwitch` 四个取值里**没有「无会话、按请求寻址」这一档**：`inPlace` 需要一条会被切换的会话，`requiresReplacement` 需要先有一条会被替换的会话，而 MongoDB 两者都没有。同样的缺口也出现在 clickhouse（库随每个 HTTP 查询下发）和 influxdb（`SHOW DATABASES` 真实枚举、库随请求下发）。**P0 必须先扩展枚举或明确定义映射规则**，否则这 3 个驱动无法给出合法的 `namespaceSwitch` 取值。 + +### 3.7 ClickHouse + +- `PoolEntry { client, base, database }`：库在建连时取自 `config.database` 并随每次查询下发，因此**库不是会话状态**。 +- `has_multi_database` = `true`；`get_databases` 查 `SELECT name FROM system.databases ORDER BY name`（真实枚举）。 +- `get_tables` 注释：ClickHouse 的 "schema" **就是** database，所以 `namespaceShape` 只有一层。 +- `cancel_query` 返回 `Ok(())`；事务三方法未覆盖；`ddl_atomicity` 未覆盖。 + +**与目标契约的差距**：同 §3.6 的枚举缺口。额外一条：ClickHouse 的 engine 变量、临时表、session 设置都是 HTTP query 参数级的，不构成会话上下文，`contextObservation: unsupported` 是准确的。 + +### 3.8 DuckDB + +- `connect` 用 `::duckdb::Connection::open(path or ":memory:")` 包在 `Arc>` 里按 `pool_id` 存，`ConnectionHandle` 的 `id` 与 `pool_id` 同值。一个 handle 一条真连接，这一点与 sqlserver 同构。 +- `get_databases` 返回 `vec!["main","temp"]`，但这两个名字**是 schema 名不是 catalog 名**——`duckdb.rs:80-98` 的 `catalog_selector` 注释明确写了这一点，所以 `namespaceShape` 不能按「单文件 = 单库（`main`/`temp`）」记。`ATTACH ':memory:' AS aux` 出现在 `duckdb.rs:831`，同样位于 `#[cfg(test)]` 内；生产路径无跨 catalog 附加。 +- 已知方言细节：注释记录 DuckDB 的 `PRAGMA` 解析器拒绝 catalog 前缀（`PRAGMA aux.table_info`），必须写成 `PRAGMA table_info('aux.t')`。 +- `cancel_query` 返回 `Ok(())`；事务三方法、`begin_read_snapshot`、`discard_connection`、`ddl_atomicity` 全部未覆盖。 + +**与目标契约的差距**：`namespaceSwitch` 与 `contextObservation` 两格待 P0 验证（[§9](#9-待-p0-验证清单) 第 3、4 条）。DuckDB 引擎本身的事务与快照能力驱动完全没有暴露，属于「引擎支持、驱动没接」，批次 2 要决定是接还是不接；不接就必须保证 `Unsupported` 是显式拒绝而非静默。 + +### 3.9 rqlite / turso + +两者结构相同：`(client, base)` 无会话元组，`get_databases` 恒返回 `vec!["main"]`，事务/快照/重置全走 trait 默认，`cancel_query` 返回 `Ok(())`。两个 crate **都没有 `sync_adapter` 模块，也没有实现 `SyncAdapter`**；sqlite 兼容的元数据读取留在各自驱动文件内（`rqlite.rs:82-89` / `turso.rs:84-91` 的 `table_info_sql`，拼 `PRAGMA {db}.table_info('t')`）。这是 P2 里**最低成本的一档**：全部能力取 `unsupported`，工作量在于把 `cancel_query` 改成显式拒绝并补契约测试。 + +### 3.10 Elasticsearch / HBase + +同样是无会话 `(client, base)`，`get_databases` 恒返回 `vec!["default"]`，`cancel_query` 返回 `Ok(())`。HBase 另有 namespace 概念（列族/表限定名），但驱动当前不暴露成可切换的命名空间。**elasticsearch 没有 `tests/` 集成测试目录**（真实服务端基线为 0），只有 `src/elasticsearch.rs:516` 与 `src/sync_adapter.rs:128` 两个 `#[cfg(test)]` 模块共 10 个单元测试。**没有 `tests/` 目录的 path 驱动共 7 个**：rqlite / turso / elasticsearch / hbase / influxdb / victoriametrics / vector——批次 3 必须先补最小可运行基线，否则这 7 个驱动的任何能力结论都没有真实协议回归保护。 + +### 3.11 InfluxDB / VictoriaMetrics + +- influxdb：`get_databases` 解析 `SHOW DATABASES` 的 results/series/values，返回真实库列表；库随请求下发 → `namespaceSwitch` 待 P0 验证（§9 第 5 条）。`cancel_query` 返回 `Ok(())`。 +- victoriametrics：`get_databases` 恒返回 `vec!["default"]`，`cancel_query` 返回 `Ok(())`。 + +### 3.12 Vector + +`(client, base)` 无会话，`get_databases` 恒返回 `vec!["default"]`，`cancel_query` 返回 `Ok(())`，事务/快照/重置全走默认。与 §3.9 同一档处理。 + +## 4. 迁移批次 + +批次划分原则：**先用最少的驱动把契约测试模板跑通并冻结，再按语义相近度扩面**。每个批次内所有驱动的 D 层用例同时转绿才准进下一批；任一驱动未转绿则整批停在原地，不允许「大部分通过」。 + +**所有 D 层测试的落点固定在驱动 crate 内**（`AGENTS.md` 驱动测试落点表 + 独立驱动开发指南 §8）：Rust 单元写在 `packages/drivers//src/*.rs` 的 `#[cfg(test)]`，集成测试写在 `packages/drivers//tests/`，`cargo test -p datazen-driver-`；驱动专属 UI 单测写在 `packages/drivers//ui/__tests__/`，`pnpm test:unit:drivers`；驱动专属 E2E 写在 `packages/drivers//e2e/`。**禁止**把这些用例加到 `src-tauri/`、`src/` 或 `e2e/specs/`。 + +### 批次 0：契约测试模板（不接任何真实驱动） + +目标：把「能力断言 + 拒绝断言」写成一份可复制的模板，让后续每个驱动只需填表。 + +- **范围**：`packages/driver-api` 新增 `capabilities.rs`（能力枚举与 `describeResource` 的返回结构）、`session.rs`、`resource.rs` 三个模块（拟新增），以及驱动侧的能力自检 harness。 +- **必做断言**： + - 每个枚举取值都有一正一反两个用例：合法值原样返回；非法/未覆盖时返回 `Unknown` 而不是猜一个 `supported`。 + - 能力缺失必须走 `DriverError::Unsupported`，**不得**返回 `Ok(())`；已建立执行记录时记 `ExecutionErrorCode::hostRejected`，尚未建立记录时直接返回 `ApiError.code=CapabilityUnsupported`（`CapabilityUnsupported` 是 §13 的 `ApiError.code`，不是 `ExecutionErrorCode` 取值；这是把当前 13 处 no-op 变成回归网的关键断言）。 + - `describeResource` 的 `ResourceDescriptor` 必含 `providerId` / `resourceKey` / `sessionContinuity` / `reusePolicy` / `initializationRequirements` / `connectionCostPolicy` / `namespaceShape`（连接管理 §5.1）。 + - `SessionObservation` 的 unknown 字段不得填入 `initialTarget` 假充确认（§5.1）。 + - **CM-08（两个编辑器隔离，H/D/F）与 CM-30（idle 连接计入预算，H/D）必须进模板**：这两条描述的是宿主侧「同一个 driver 实例同时服务两个编辑器、上下文互不破坏」与「预算必须统计真实 idle 连接」，不是某个方言的语义，因此对全部 15 个驱动成立。模板里先把两条的用例骨架写出来（驱动只需提供自己的 `ResourceDescriptor` 与连接统计钩子），后续驱动行就不必再重复列它们。 +- **进出门槛**：模板本身是一个可运行的 hostless harness（`cargo test -p datazen-driver-api`），且在至少一个「全部能力 unsupported」的桩驱动上能全绿。 + +### 批次 1：代表驱动（每种语义模型各一个） + +选这 4 个是因为它们把 §2.2 的三条结构事实全部覆盖了一遍，且彼此没有共享实现库。 + +| 驱动 | 选它的原因

`plan.source_driver_protocol` / `plan.target_driver_protocol`，执行时再次核对（`src-tauri/src/commands/data_transfer/exec.rs:125,150,487-488`，取值辅助函数 `plans::driver_protocol_version` 在 `plans.rs:156`）。 + +**闸门现状与 §5.4 目标之间的缺口**：`pv > PROTOCOL_VERSION` 分支今天是「警告后照常加载」，也就是说宿主面对一个声明了更高协议版本的驱动时会静默进入未知兼容态，而 §5.4 要求的是「不静默降级」。P2 必须先在**硬拒绝（返回 `Err`、不 `create()`）**与**加载但标记为不可用并禁止 `execute_driver_command`**之间**二选一**（无论选哪个都不得以「下调 `MIN` 让它落进降级分支」的方式绕过），再把它落成门禁；定案见 §5.4 第 5 条与 [§9](#9-待-p0-验证清单) 待定义 H。**在定案并落成门禁前，不能声称「版本更高的驱动会被拒绝」。** + +### 5.2 版本是怎么声明的 + +`DatabaseDriverFactory` 的 `protocol_version() -> u32` 有默认体，返回 `crate::PROTOCOL_VERSION`。**全部 15 个 path 驱动都没有覆盖它**；唯一覆盖者是 git 驱动 `packages/drivers/superset/src/lib.rs:1197`。 + +这意味着：**驱动只要不显式声明就自动跟随 `driver-api` 的版本**，只要升级 `PROTOCOL_VERSION`，所有 path 驱动同步升版、闸门恒走「当前」分支。代价是**驱动无法为旧宿主做兼容**——这正是必须由 `MIN_PROTOCOL_VERSION` 承接的部分。 + +### 5.3 哪些改动是 breaking + +| 改动 | 是否 breaking | 处理 | +| --- | --- | --- | +| 新增 trait 方法且带 fail-closed 默认体 | 否 | 升 `MIN` 不变；驱动不改也能编 | +| 新增 trait 方法**没有**默认体 | 是 | 升 `MIN`，要求所有驱动显式实现后才算合规 | +| 改能力枚举取值或语义 | 是 | 升 `MIN` + 升 `PROTOCOL_VERSION` | +| 改 DTO 字段的必填性 | 是 | 升 `MIN` + 升 `PROTOCOL_VERSION` | +| 放宽已声明 `unsupported` 的行为 | 否 | 降级模式下按 `false` 处理即安全 | +| 收紧已声明 `supported` 的行为 | 是 | 视为 breaking，需按 breaking 发布 | + +判定原则是**「老驱动在新宿主上是否仍能安全运行」**。`capabilities.rs` 里所有新枚举都按 fail-closed 默认（`unknown` / `unsupported`）设计，正是为了让「新增能力」本身不成为 breaking。 + +### 5.4 「协议升级与驱动发布是原子兼容门槛」 + +这条门槛的落地机制如下。 + +**禁止的做法**：宿主遇到驱动行为不兼容时，下调 `MIN_PROTOCOL_VERSION` 让旧驱动继续加载，并在降级模式下把缺失能力当 `false` 用。这会把兼容性问题变成运行期静默降级——正是「新增能力缺失不会 no-op 成功」要禁止的那类问题。当前 `MIN_PROTOCOL_VERSION = 1` 是在 `PROTOCOL_VERSION = 4` 之前三次演进中留下的兼容窗口，它的存在本身不代表可以随时下调。 + +**正确的做法**：任何 breaking 改动必须让**版本号、驱动实现、驱动发布**三者同一次落地完成，具体为： + +1. 在 `packages/driver-api` 改 trait / 枚举 / DTO，同时把 `PROTOCOL_VERSION` 从 N 提到 N+1。 +2. **同一个提交内**把所有受影响的 path 驱动改到能通过新契约的形态（缺失能力显式 `Unsupported`，不得 `Ok(())`）。 +3. path 驱动在**本仓库内**改完即发布，不存在跨仓库同步窗口。 +4. git 驱动在**自己的仓库**里跟进，在 DataZen 侧以 `drivers-registry.json` 的**钉死 `ref`**（`source: "git"` + 指定 `ref`，参见 `olap` 条目 `7096c8737dbe25ab4529e5c3997c9f67309154d9`）提交 DataZen registry PR。钉死 ref 是可复现构建的前提：registry 不指向浮动分支，也不指向未打 tag 的提交。 +5. 宿主升级后，`PROTOCOL_VERSION` 必须 ≥ 全部已发布驱动的 `protocol_version()`。**注意这里的现状是缺口而不是保障**：`registry.rs:134-140` 的 `pv > PROTOCOL_VERSION` 分支目前只是 `tracing::warn!` 然后照常加载，既没有拒绝、也没有把它挡在降级分支之外。要让这条真正成立，P2 必须先在**硬拒绝（返回 `Err`、不 `create()`）**与**加载但标记为不可用并禁止 `execute_driver_command`**之间**二选一并落成门禁**（定案见 [§9](#9-待-p0-验证清单) 待定义 H；闸门现状见 §5.1）——**在定案并落成门禁前，「版本更高的 git 驱动会被拒绝、不静默降级」这句话是不成立的**。 + +**冲突时的判据**：如果某个 breaking 改动无法在本仓库内一次性覆盖全部 path 驱动（例如需要 3 个 git 驱动分别发版），那它**不能**靠下调 `MIN` 蒙混过关，必须先让 DataZen 侧以新 `PROTOCOL_VERSION` 构建、通过 registry 钉 ref 升级全部 git 驱动，最后再打开闸门。在中间状态，宿主应保持 `PROTOCOL_VERSION` 不变、拒绝加载尚未跟进的新能力，而不是接受一个半兼容的组合。 + +**AI 侧同理**：`AI_PROTOCOL_VERSION` 变更时需要同步更新所有 AI Provider 插件，这条规则在 `AGENTS.md` 中已写明，与本文的驱动协议规则是同一套原子门槛的两次应用。 + +## 6. 过渡 adapter：遗留驱动的独立受控 Command + +### 6.1 允许与禁止 + +连接管理 §5.2 的收尾约束是：**「遗留驱动可以支持独立受控操作，但不能因为『池大小为 1』就声明固定会话：底层重建和不同 consumer 仍会破坏语义。」** 拆成可执行的两侧： + +**允许（保留独立受控 Command，不必立刻实现资源契约）**： + +- 遗留 trait 上已有的独立操作继续可用，只要它自身携带完整语义（例：sqlserver 的 `set_identity_insert` 本身就是会话级开关，其作用域由驱动自己负责；sqlserver 的 `discard_connection` 本身就是一次性丢弃）。 +- 宿主可以对 `unsupported` 的能力继续提供**明确标注降级**的旧路径，但该路径必须在 UI 与 `ExecutionCompletion.effectOutcome` 上标出 `partial` 或 `unknown`，不得呈现为成功。 +- 迁移期的驱动可以同时实现新旧两套接口，新接口为准，旧接口作为 adapter 转发。 + +**必须永不开放**： + +- **不得因为「池大小为 1」或「每个 `pool_id` 只有一条连接」就声明 `statefulSession: supported`。** 具体到本文的三个驱动：sqlite 的 `max_connections(1)` 是 sqlx pool；duckdb 的 `Arc>` 是互斥访问而非基线校验；redis 的常驻 `live` 连接承载了大多数操作，但同样没有基线校验、没有独占声明。§5.2 的反例原话就是这一条。 +- **不得因为「驱动没实现」就把 `Unsupported` 翻译成成功。** trait 默认体已经是 fail-closed 的（`discard_connection`、`begin_read_snapshot`、`cancel_query_with_execution` 都返回 `Unsupported`），adapter 若把它们捕获后返回 `Ok(())`，等于抹掉默认体的保护。 +- **不得让 adapter 跨 consumer 复用会话级句柄。** §6.5 的句柄登记机制还不存在，adapter 若在没有登记的情况下交出句柄，宿主将无法对句柄终态负责。 + +### 6.2 退役条件与删除时机 + +每个驱动从「adapter 双轨」切换到「只走资源契约」的条件是全部满足： + +1. 该驱动在 §2.1 矩阵中的每一格都已是 §5.2 的合法取值，不再有「待 P0 验证」。 +2. §5.1 的 9 个操作全部实现，且 `executeOnResource` 不再自行从随机池取连接。 +3. 所属批次的 D 层用例全绿，且 `CM-19` 明确断言「没有把单连接池假装成固定资源」。 +4. `resetResource` 要么返回 `Clean`（通过 CM-26 / CM-69）要么返回 `Discard`，没有第三条静默路径。 +5. 宿主对该驱动的所有 namespace API 调用点已迁移。当前调用点包括 `src-tauri/src/data_transfer/execute/dispatcher.rs:696`（`tgt_driver.discard_connection(tgt_handle)`）、`src-tauri/src/data_sync/execute.rs:196-199`（`executor.discard_connection()`，仅在 `cleanup_error` 已发生时）与 `src-tauri/src/commands/sync/exec.rs:88-93`（同一 executor 的转发实现）、`src-tauri/src/workflow/executor.rs:60`（持有 `driver_has_multi_database: bool`）、`src-tauri/src/bootstrap/run.rs:250,258`（注册 `close_database` / `get_open_databases`）、`src-tauri/src/testing/mock_driver.rs:361-374`（伪造 `close_database` / `open_databases`）。这几处正是 P2 要收敛的宿主侧驱动分支。 + +**删除时机**：adapter 的删除与**宿主侧对应分支的删除**必须同一个提交。只删驱动侧 adapter 而留宿主分支，宿主就会退回到 no-op；只删宿主分支而留驱动侧，则驱动仍可能被旧路径调用。这个原子性与 §5.4 的协议发布门槛是同一条原则的两次应用。 + +## 7. unsupported 的拒绝断言要求 + +连接管理 §17 的收尾约束是：**「能力 Unsupported 的 driver 测试断言『正确拒绝』，不能静默 skip 后宣称能力已验证。真实测试环境不可用必须报告未验证范围，不能用 fake 代替真实协议结论。」** + +### 7.1 头号违反点：13 处 `cancel_query` 的 no-op 成功 + +15 个 path 驱动的 `cancel_query` 实现体逐个读过，结果是 **13 个返回

`Err(Unsupported(...))`）。也就是说它的 `preciseCancel` 在矩阵里是明确的 `unsupported`，而 legacy 取消却静默返回成功——宿主据此显示「已取消」，用户以为写事务被回滚了，实际没有。这正是 §13 说的「不能因为『看到取消』就写 rolledBack」。 + +**P2 必须做的改造**：这 13 处全部改为显式 `Unsupported`（或按 §5.1 的 `requestCancel` 语义返回 `CancelReceipt.disposition = unsupported`），并让宿主把 `unsupported` 呈现为「该连接不支持取消，请显式中止会话」，而不是「已取消」。 + +### 7.2 逐能力的拒绝断言要求 + +对每一个标 `unsupported` 的能力，M

读这张表时可以直接回答「某个能力在哪些驱动上可用、在哪些驱动上必须拒绝」——前者是 `supported`/`verified`/`inPlace` 的格，后者必须配 §7.2 的对应拒绝断言。 + +### 10.3 阶段完成的判据 + +P2 完成时，上表所有章节都应转为「已实现」：§2.1 不再有「待 P0 验证」格、§9 清单清空、§7.1 的 13 处 no-op 全部改为显式拒绝、§6.2 列出的宿主侧驱动分支（`driver_has_multi_database`、`close_database` / `get_open_databases`、dispatcher 的 `discard_connection` 调用）全部删除或替换为契约调用。按 `AGENTS.md` 文档纪律，届时应把本文的「当前」内容改写为已实现事实并入 [连接管理](connection-management.md)，本文转为协议与矩阵的长期维护说明。 + +## 与既有设计的关系 + +- **[连接与资源运行时设计](connection-management.md)** 是本文的上游契约：§3 借用它的 `ResourceDescriptor` 七项必填字段与 `namespaceShape`，§4 的批次以它的 §16 用例编号为门槛，§6 沿用 §5.2 的「遗留驱动可以支持独立受控操作」约束与 §9.4 的归池前检查，§7 的「不得静默 skip」引自 §17。本文**不重新定义**它的任何枚举取值、任何 trait 方法、任何用例编号。 +- **[平台开发计划](../../development/platform-development-plan.md)** 是本文的阶段归属：本文的批次划分对应 P2 的交付与退出门槛，§10.2 对应 P10 的「通用 contract × driver 矩阵」。本文只解释「怎么清点、怎么分批、怎么升版本」，不重复计划里已有的排期与里程碑。 +- **[Driver API 依赖边界](../../development/driver-api-dependency-boundary.md)** 是 §8 的规范来源：公共接口只用标准库类型、API 自有类型和 serde，宿主类型、Tokio、HTTP 客户端、SQLx 的禁止范围由该文档定义，本章只补充「私有实现依赖 vs 公共 API 表面」的区分与改动后的门禁命令。 +- **[可选驱动](../../development/optional-drivers.md)** 与 **[独立驱动开发指南](../../development/independent-driver-development.zh-CN.md)** 是 §1.3 与 §4 测试落点的来源：git 驱动钉 ref 升级、驱动专属测试只写在 `packages/drivers//` 之下、禁止把驱动专属测试加到 Host，均引自这两份文档。 +- **代码事实**（而非上述任何文档）是 §2 矩阵与 §7.1 清单的唯一证据来源。凡本文与代码不一致，以代码为准并回头修订本文。 + +## 本文不覆盖什么 + +- **不定义 `capabilities.rs` / `resource.rs` / `session.rs` 的具体 API 形状。** §5.1 的 9 个操作、§4 的 DTO 字段、§5.2 的能力枚举都由连接管理定义；本文只说明它们对现有 trait 的映射关系，不新增方法、不新增类型、不重命名。 +- **不设计 Host 侧运行时。** 连接池、Tokio actor、channel、semaphore、`PoolKey`、`BudgetPort` 的实现、Lease/Attachment 状态机、结果流与背压策略属于 Host 连接运行时（P3 及之后），不在本文范围。本文只在 §8.2 说明驱动如何配合预算计数。 +- **不覆盖 git 驱动（kiwi / olap / superset）的能力矩阵。** 它们在 `drivers-registry.json` 里是 `source: "git"`，不在 workspace 内，`describeResource` 只能由各自仓库实现。本文只在 §1.3 记录它们的存在与计数差异，在 §5.4 记录它们的版本升级机制（钉 ref 升级）。 +- **不覆盖前端 UI 与 i18n 的驱动能力呈现。** 能力如何在 UI 上呈现、降级路径如何标注，属于前端设计与宿主绑定层（见独立驱动开发指南 §6），本文只规定「必须标注降级、不得呈现为成功」这条行为要求。 +- **不排期、不列进度、不列缺陷清单。** 按 `AGENTS.md` 文档纪律，本文是一次性设计产物；落地后改写为已实现事实并入对应架构文档。 +- **不重新评估 `AGENTS.md` 中已有的驱动选型、双版本构建、四维扩展体系与测试落点规则**，只引用。 +- **不代替真实测试环境。** §9 的「待 P0 验证」项必须由真实服务端测试环境下的 D 层用例判定；按 §17，测试环境不可用时必须报告未验证范围，不能用 fake 代替真实协议结论。 diff --git a/docs/architecture/platform/fake-runtime-fixtures.md

§4.5](shared-boundaries-and-ports.md#45-会话目录预算与令牌端口)）。这里涉及三个不同对象，不得混为一谈：`: keepalive` 是 SSE 传输层的注释行；[§8.2](#82-last-event-id-回放) 的 1024 条环形回放缓冲是每 stream 的事件缓冲；`idle_expires_at` 是**登录会话行**（§4.3）的空闲寿命，只由入站请求顺延。因此一个只挂 SSE、不再发其他请求的客户端会在登录空闲期到期后被关闭，这是有意的语义——保活必须发业务请求或重新登录。 + +### 8.4 权限复核与登录过期 + +握手鉴权**不是**唯一鉴权点。每个心跳周期在同一任务上复核三件事： + +1. 登录会话行未撤销、未超过 `absolute_expires_at`、且未超过

`permission_revoked` / `session_lost`），**然后关闭流**。客户端收到 `auth_required` 必须先 `close()` 掉 `EventSource` 再跳转登录，否则浏览器会自动重连形成登录风暴；服务端对此以 204 响应抑制自动重连（CM-56、CM-59 的 **W** 断言）。`W` 是上位泛称，阶段性落点按[开发计划

模块结构 + +`src-tauri/src/workflow/` 实际有 14 个源文件。`mod.rs` 只声明 9 个模块：8 个 `pub mod` 加 1 个 `pub(crate) mod migration`（`migration` 不是公开模块）；`conditions.rs`、`context.rs`、`data_step.rs`、`executor.rs` 更是通过 [`workflows.rs`](../../../src-tauri/src/workflow/workflows.rs) 的 `#[path]` 声明为私有子模块，不出现在 `mod.rs` 中。`[已实现的 Workflow 架构](../backend/workflow.md)` 的文件清单（10 项）缺 `data_step.rs`、`error.rs`、`migration.rs`、`scheduler.rs`，且把 `#[path]` 子模块当成平铺模块描述。 + +`data_step.rs`（749 行）**不涉及任何数据库资源**，内容是 `merge` / `transform` 的行集合并与表达式求值（`run_merge`、`run_transform`、`evaluate_expression`）。`context.rs` 负责变量与模板上下文，`conditions.rs` 负责条件比较。 + +### 2.2 定义模型 + +[`model.rs`](../../../src-tauri/src/workflow/model.rs) 的 `WorkflowDefinition` 为扁平结构：顶层 `connection`（默认连接，可为 `{{var}}` 模板）与 `database`（默认库）被 step 继承；**没有任何 block 层级字段**。`WorkflowStep` 用 `#[serde(tag = "type")]` 区分 `query` / `command` / `ai` / `condition` / `foreach` / `migration` / `merge` / `transform`。 + +| 观察 | 证据 | +| --- | --- | +| `query` step 有顶层 `database` 字段 | `WorkflowStep::Query { id, sql, connection, database, timeout_secs, on_error }` | +| `command` step **没有**顶层 `database` 字段 | `WorkflowStep::Command { id, command, connection, input, timeout_secs, on_error }`，库名只能写在 `input.database` | +| `ai` step **没有** `connection` / `database` 字段 | AI 步骤当前不接触目标资源 | +| `version: Option` 存在 | `WorkflowDefinition.version` | +| 三个内建 YAML 均未写 `version` | [`src-tauri/resources/builtin-workflows/`](../../../src-tauri/resources/builtin-workflows) 下的 `hello-query.yaml`、`cross-db-sample.yaml`、`ai-summarize.yaml` | + +### 2.3 版本字段的现状（重要） + +`version` 字段在**全仓库范围内只被写入，从未被读取**： + +- 没有任何按版本分派的解析代码（无 `match version`、无 `CURRENT_VERSION` 比较，三个内建 YAML 也未设置该字段）； +- 生产代码写入点只有 `src-tauri/src/dashboard/create.rs:64` 的 `version: None` 字面量；其余 11 处全在测试代码内（`workflow/registry.rs:260`、`workflow/executor.rs:901/938/972`、`workflow/scheduler.rs:231`、`workflow/migration.rs:892`、`commands/dashboard.rs:461`、`commands/ai/integration_tests.rs:356/906/1039/1085`），其中仅 `integration_tests.rs:356` 写 `Some("1")`，同样无人读取。 + +对比：仓库中其他"定义版本"确有实现——`schema_diff/profile.rs:44-47` 的 `CURRENT_VERSION` 并在遇到未知版本时报 "unsupported ... version"；`data_sync::SyncProfile`、`data_transfer::profile.rs` 同样有 `CURRENT_VERSION`；`store/favorites/migrate.rs` 有 `MIGRATION_VERSION`。Workflow 是这些带 `CURRENT_VERSION` 校验的定义中唯一未校验的一个；另需注意 `store/settings.rs:15` 的 `OnboardingState.version` 同样只写不读（生产路径只读 `completed`）。 + +### 2.4 目标解析与资源获取 + +[`executor.rs:124`](../../../src-tauri/src/workflow/executor.rs)： + +```rust +let workflow_connection = workflow.connection.as_deref().or(connection_id); +let workflow_database = workflow.database.as_deref(); +``` + +`connection_id` 是**调用方传入的运行时参数**，由 IPC / MCP / 调度器决定，是 P6 要消除的隐式目标来源。当前优先级因此只有两级：step 显式 → (workflow 默认 → 调用方 connectionId)。 + +query 分支（[executor.rs:444-489](../../../src-tauri/src/workflow/executor.rs)）： + +1. `step_database = step.database`（可为 `{{var}}`，先做模板解析）； +2. `inherited_database = workflow_database`； +3. `resolved_database = step_database.or(inherited_database)`； +4. 仅当 `resolved_database.is_none()` 且 `database_is_required(connection_database, driver_has_multi_database)` 时报 `MissingDatabase`；该判定只对多库驱动生效，PostgreSQL 驱动在 `resolve_connect_database` 中硬编码 `"postgres"`。 + +command 分支（[command_runtime.rs`](../../../src-tauri/src/workflow/command_runtime.rs)）： + +1. `resolve_connection_id(step, workflow_connection)` → `step.effective_connection(workflow_connection)`，缺失报 `MissingConnection { step_id }`； +2. `inject_inherited_database(input, workflow_database)`：显式非空 `input.database` 优先，空白串按未设置处理，trim，非对象则空操作； +3. `connection_manager.resolve_session_for_connection(connection_id)` 返回 `(runtime_id, driver, handle)`；该方法内部按 **`session_owner_map` 里 owner == 配置 id** 查找已有会话，找不到则 `connect(connection_id)` 新建（`resolve_session_for_connection` 见 [sessions.rs:92-103](../../../src-tauri/src/services/connection_manager/sessions.rs)，owner 查找与新建在同文件 `get_or_connect_session`，[sessions.rs:8-37](../../../src-tauri/src/services/connection_manager/sessions.rs)）； +4. 在 `driver.command_definitions()` 中查 id，未找到报 `UnsupportedCommand`，`metadata.workflow == false` 报 `CommandNotInWorkflow`； +5. `validate_command_input` + 按 `permission_mode` 的 `check_command_access`；id 为 `"query"` / `"execute"` 时再过 `sql_guard::check_sql` 与 `mcp::permission::check_sql_allowed`； +6. `inject_sql_target_fields(&mut input, database, schema)` 后 `driver.execute_command`。 + +`command_runtime.rs:115-119` 的注释明确记录了目标定位策略：**不再做 session 切库**，目标随 command input 下传，由支持 `qualify_sql_target` 的驱动就地改写未限定关系名；当前 6 个 SQL 驱动（clickhouse、sqlite、duckdb、mysql、postgres、sqlserver）均已实现该方法，mongodb 虽声明 `has_multi_database` 但不走 SQL 路径。 + +### 2.5 调度、历史与 Job + +|

`TransactionScope` 目前唯一的生产消费者是 `schema_diff/deploy.rs`。`migration.rs`（三件套 step 执行器，**不是定义版本迁移机制**）内部用 `RuntimeSession { db_session_id, database, schema }` 表达自己的端点会话并在结束时 `release`，同样不暴露给 Workflow

Workflow**：[`components/ai/WorkflowPanel.tsx:104`](../../../src/components/ai/WorkflowPanel.tsx) 在 `handleExecute`（L99-107）里执行时传 `connectionId: dbSessionId`，而 `dbSessionId` 来自 `activeConnections[conn.id]?.dbSessionId`（连接窗口的运行时会话标识）。后端 `resolve_session_for_connection` 按 owner **配置 id** 查表，按[命名规范](../../../AGENTS.md) 这是被禁止的双模混用。同一页面的独立 Workflow 窗口（[`WorkflowPage.tsx:417`](../../../src/windows/workflow/WorkflowPage.tsx)）则完全不传该参数。 + +这正是第 9 节"AI/MCP/Wapp 与 Workflow 边界"要清理的入口耦合，实际失败表现列入[第 12 节](#12-待-p0-验证清单)。 + +--- + +## 3. 目标资源模型：三种执行单元 + +### 3.1 定义 + +| 执行单元 | 资源范围 | 生命周期 | 原子性承诺 | 状态跨 step | +| --- | --- | --- | --- | --- | +| **独立 step** | 每次执行独立初始化的短操作资源 | 单个 step | 无 | 不保留 | +| **session block** | 一条跨 step 连续的固定 Lease | block 首个 step 开始 → 最后一个 step 结束 | 无 | 保留（临时对象、会话变量、已确认上下文） | +| **transaction block** | 一条固定 Lease + runtime 托管事务 | begin → commit/rollback 确认 | 提交边界由 runtime 保证 | 保留，且在提交前对外不可见 | + +三种单元共享同一套约束：资源 owner 明确（[第 5 节](#5-session--lease--budget-集成)）、target 操作不改变任何其他 session 的默认库或事务（[INV-05](connection-management.md#3-不可破坏的不变量)）、实际上下文由 driver 确认而非 SQL 文本推断（[INV-04](connection-management.md#3-不可破坏的不变量)）。 + +### 3.2 独立 step + +每次执行独立初始化资源，步骤内的 `USE` / `SET search_path` 等会话状态**只在该 step 内有效**，不泄漏到后续 step，也不在步骤之间保留临时对象。独立 step 用顶层 `steps:`（v2 保留的 v1 扁平容器，见 [§8.1](#81-顶层) 与 [§10.2](#102-按版本分派解析)），无需 block 包裹。 + +```yaml +version: "2" +id: independent-steps +name: 独立 step 默认语义 +steps: + # step1 自己的资源上切库；只在本 step 内生效 + - type: query + id: probe + connection: "{{conn}}" + database: "reporting" + sql: "SELECT

workflow 默认目标 + - type: query + id: archive + connection: "{{archive_conn}}" + sql: "SELECT count(*) AS archived FROM orders" +``` + +这与 [CM-50](connection-management.md#165-三件套与-workflow) 的断言一一对应：step1 用自己的资源 `USE B`，step2 用 A，step3 用 C，step1 状态不泄漏，资源全部清理。**旧定义在目标 runtime 下的默认语义就是独立 step**（[第 10.4 节](#104-旧定义在目标-runtime-下的默认语义)）。 + +### 3.3 session block + +block 内所有 step 在**同一条物理资源**上串行执行，状态跨 step 保留；块结束才释放。并行分支各自获得独立资源（[第 6 节](#6-并行分支与重试)），**同一 session block 永不并行执行**——同一 blockId 在同一 Workflow run 内同时只能有一个执行实例。 + +```yaml +version: "2" +id: session-block-demo +name:

触发资源获取，其后所有 step 复用同一 Lease，满足 [INV-02](connection-management.md#3-不可破坏的不变量)（driver 不得内部换连接）。 +2. 同一 session 的普通执行串行（[INV-03](connection-management.md#3-不可破坏的不变量)）；取消走独立控制路径。 +3. block 内的 step 不得声明 `database` 变更到需要**重连**的库（如 PostgreSQL 换库需新连接）。声明了则静态校验拒绝，运行期只能通过 driver 声明的**不需重连**的上下文切换（如 MySQL `USE`），且切换后必须由 driver 确认实际上下文（[INV-04](connection-management.md#3-不可破坏的不变量)）。 +4. block 结束无条件释放：走[§9.4 归池前检查](connection-management.md#94-归池前检查)，失败不归池。 +5. session block **可以**执行原生任意 SQL，但**不提供** runtime 管理的整块原子性（[第 7 节](#7-transaction-block-计划预校验)）。 + +### 3.4 transaction block + +runtime 控制 begin /

order_id: "{{order_id}}", amount: "{{amount}}" } + + - type: query + id: assert_balance + sql: "SELECT balance FROM ledger WHERE order_id = '{{order_id}}'" +``` + +规则： + +1. **开始前**由 driver 校验整份计划能否保证提交边界（[第 7 节](#7-transaction-block-计划预校验)），不能证明则整块拒绝，返回 `UnsupportedPlan`，**不执行任何语句**。 +2. 事务开启时若实际事务状态为 `unknown`（[§6.1 Session 状态机](connection-management.md#61-session-状态机)），拒绝开始，返回 `TransactionResolutionRequired`。 +3. 任一 step 失败 → runtime 执行 rollback 并记录 `effectOutcome`；只有**已证实回滚**才允许重试整块（[第 6.2 节](#62-重试范围)）。 +4. commit 发出后若结果无法确认 → `effectOutcome = unknown`，`errorCode` 取**实际成因**（`protocolError` / `timeout`），**不自动重试**（[INV-12](connection-management.md#3-不可破坏的不变量)）。 +5. 需要重连的 database 变更**不得**进入已开启的 transaction block；静态校验拒绝，运行期也不提供中途换库。 +6. 事务句柄按 [§6.5

The gate therefore refused objects Data Transfer already recreates on the target. Narrow unsupported_transfer_structure_query down to the three genuinely inexpressible kinds — computed columns (no IR concept), CHECK constraints (no emission path) and identity columns with a non-default seed/increment (auto_increment_keyword hardcodes IDENTITY(1,1)) — matching the granularity of the PostgreSQL adapter. Escaping invariants are unchanged. Removing the index branch exposed a second blocker: parse_indexes reports CLUSTERED / NONCLUSTERED / UNIQUE_CONSTRAINT:, while the shared render_index_ddl only accepts an ordinary B-tree index, and nothing in the host normalizes it, so every secondary index would have failed the plan instead of the precheck. Normalize that vocabulary in table_objects_to_ir, at the point where the catalog wording enters the IR, so all target adapters work — not only SQL Server itself. Foreign-key actions already fit the shared renderer, and a genuine SET DEFAULT still fails closed. Also report index names as table-scoped: SQL Server identifies an index by (object_id, index_id), so the same name may be reused across tables, while foreign keys remain schema-scoped objects in sys.objects. --- .../drivers/sqlserver/src/sync_adapter.rs | 135 +++++++++++++--- .../sqlserver/tests/sync_adapter_smoke.rs | 153 +++++++++++++++++- 2 files changed, 267 insertions(+), 21 deletions(-) diff --git a/packages/drivers/sqlserver/src/sync_adapter.rs b/packages/drivers/sqlserver/src/sync_adapter.rs index dcdb3d7b3..768de474c 100644 --- a/packages/drivers/sqlserver/src/sync_adapter.rs +++ b/packages/drivers/sqlserver/src/sync_adapter.rs @@ -2,8 +2,9 @@ use datazen_driver_api::sync::contract_from_column; use datazen_driver_api::{ - BoxedSyncAdapter, ColumnSchema, IRColumn, IRDefault, IRType, SyncAdapterFactory, - SyncKeyContract, SyncKeyKind, SyncSourceAdapter, SyncTargetAdapter, Value, + BoxedSyncAdapter, ColumnSchema, IRColumn, IRDefault, IRForeignKey, IRIndex, IRTableObjects, + IRType, SyncAdapterFactory, SyncKeyContract, SyncKeyKind, SyncSourceAdapter, SyncTargetAdapter, + TableSchema, Value, }; pub struct SqlServerSyncAdapter; @@ -93,6 +94,27 @@ fn base_type(raw: &str) -> String { lower } +/// Map SQL Server's catalog index-type vocabulary onto the dialect-neutral +/// index model used by the transfer IR. +/// +/// `CLUSTERED` / `NONCLUSTERED` — and the `UNIQUE_CONSTRAINT:` prefix the +/// catalog parser adds for constraint-backed unique indexes — describe +/// physical layout and constraint backing rather than a different index kind: +/// an ordinary `CREATE [UNIQUE] INDEX` reproduces the indexed columns and +/// uniqueness, which is exactly what the IR can carry.

charset=UTF-8 Content-Transfer-Encoding: 8bit Lock in the fail-closed structure precheck and the catalog index-type translation that commit 93bd6bce9 introduced, so neither can silently regress back into a permissive or over-rejecting gate. Drive the index tests from real parse_indexes output rather than hand-written index_type strings: the complete set of IndexInfo.index_type values production can emit is enumerated as a closed set, and each one is run through table_objects_to_ir plus the shared render_index_ddl. That keeps the catalog vocabulary and the portable mapping from drifting apart unnoticed, and proves the normalization is a translation rather than a blanket reset — a type the parser refuses (HASH) is still rejected, and a remotely referenced action the emitter cannot express (SET DEFAULT) still fails closed after its precheck branch was removed. The precheck test additionally pins the escaping invariants: catalog brackets doubled, schema/table apostrophes doubled, no prefix for a blank catalog, and exactly two UNION ALL separators so the removed index and foreign-key branches cannot come back through another catalog view. --- packages/drivers/sqlserver/src/metadata.rs | 237 ++++++++++++++++++ .../sqlserver/tests/sync_adapter_smoke.rs | 157 ++++++++++++ 2 files changed, 394 insertions(+) diff --git a/packages/drivers/sqlserver/src/metadata.rs b/packages/drivers/sqlserver/src/metadata.rs index 25e2e810a..b5cb729a7 100644 --- a/packages/drivers/sqlserver/src/metadata.rs +++ b/packages/drivers/sqlserver/src/metadata.rs @@ -527,6 +527,7 @@ fn incomplete(message: impl Into) -> DriverError { #[cfg(test)] mod tests { use super::*; + use datazen_driver_api::{TableOptions, TableSchema}; const DATABASE_COLLATION: &str = "SQL_Latin1_General_CP1_CI_AS"; @@ -1062,4 +1063,240 @@ mod tests { ForeignKeyDeferrability::NotDeferrable ); } + + /// One row in the `indexes_sql` projection order: index_id, name, + /// is_unique, is_primary_key, type_desc, is_unique_constraint, has_filter, + /// is_disabled, is_hypothetical, key_ordinal, column_name, + /// is_included_column, is_descending_key, data_space_type. + fn index_row( + id: i64, + name: &str, + unique: bool, + primary: bool, + type_desc: &str, + unique_constraint: bool, + column: &str, + ) -> Vec> { + vec![ + Some(Value::Integer(id)), + text(name), + bit(unique), + bit(primary), + text(type_desc), + bit(unique_constraint), + bit(false), + bit(false), + bit(false), + Some(Value::Integer(1)), + text(column), + bit(false), + bit(false), + text("FG"), + ] + } + + /// Render a parsed catalog index list through the Data Transfer IR mapping + /// and the shared `SyncTargetAdapter` index emitter, returning + /// `(name, IR index_type, rendered DDL)`.

charset=UTF-8 Content-Transfer-Encoding: 8bit unsupported_transfer_structure_query fell back to `dbo` only when the schema was absent, so an explicit Some("") rendered `s.name = N''`. That predicate matches no row in sys.schemas, the precheck reported zero unsupported objects, and Data Transfer admitted every table unchecked — the exact fail-open inverse of what this gate exists to prevent. Today the hazard is unreachable: the only caller passes the output of Endpoint::normalized_schema(), which yields either None or an already trimmed non-empty string. This is defense in depth for the next caller, so treat blank as absent explicitly. Trim before the emptiness check rather than after, so a whitespace-only schema takes the same path as an absent one, and a padded real schema name resolves instead of silently matching nothing. Apostrophe escaping still runs after the fallback decision, and the catalog, table and branch count are untouched. --- .../drivers/sqlserver/src/sync_adapter.rs | 55 ++++++++++++++++++- 1 file changed, 54 insertions(+), 1 deletion(-) diff --git a/packages/drivers/sqlserver/src/sync_adapter.rs b/packages/drivers/sqlserver/src/sync_adapter.rs index 768de474c..b0ff739b2 100644 --- a/packages/drivers/sqlserver/src/sync_adapter.rs +++ b/packages/drivers/sqlserver/src/sync_adapter.rs @@ -305,7 +305,15 @@ impl SyncSourceAdapter for SqlServerSyncAdapter { } else { format!("[{}].", database.replace(']', "]]")) }; - let schema = schema.unwrap_or("dbo").replace('\'', "''"); + // A blank schema must fall back to `dbo`, exactly as an absent one + // does.
