DriverInterface (core, 13 methods) and IDataDriver (spec, 28 methods) were two competing driver contracts. All plugins implemented the minimal one, leaving protocol gaps undetectable by CI due to as any casts.

Contract unification

  • spec/contracts/data-engine.ts: DriverInterface is now type DriverInterface = IDataDriver (deprecated alias)
  • core/contracts/data-engine.ts: Removed duplicate definition; re-exports from spec
  • core/index.ts: Added IDataDriver export alongside deprecated DriverInterface

Driver implementations aligned to IDataDriver

  • driver-sql: Added findStream, upsert, bulkUpdate, bulkDelete, commit, rollback, dropTable, explain. Full DriverCapabilities object.
  • driver-memory: Full DriverCapabilities alignment (18 missing capability flags added)

Breaking return type changes

  • updateMany / deleteMany → return number (count), not { modifiedCount } / { deletedCount }
  • delete → returns boolean, not any

Usage

// Before: minimal interface, many methods optional, no capability descriptor required
import type { DriverInterface } from '@objectstack/core';
class MyDriver implements DriverInterface { ... }

// After: single authoritative contract with full capability declaration
import type { IDataDriver } from '@objectstack/spec/contracts';
class MyDriver implements IDataDriver {
  readonly supports = { create: true, read: true, /* ... all capabilities */ };
  // All 28 methods must be implemented (4 optional: getPoolStats, updateMany, deleteMany, explain)
}

// DriverInterface still works as deprecated alias
import type { DriverInterface } from '@objectstack/core'; // resolves to IDataDriver

Backward compatibility

  • DriverInterface preserved as deprecated type alias — existing imports compile
  • commitTransaction/rollbackTransaction on SqlDriver preserved as deprecated wrappers
  • DriverInterfaceSchema (Zod) in data/driver.zod.ts unchanged

<issue_title>核心数据接口 DriverInterface / IDataDriver 定义存在分裂,导致所有 Driver 插件实现不一致</issue_title>
<issue_description>## 问题描述
目前 packages/core/src/contracts/data-engine.ts 中定义的 DriverInterfacepackages/spec/src/contracts/data-driver.tsIDataDriver 存在明显分裂。迁移和新开发的数据驱动插件(如 driver-sql、driver-memory)的实现对象和测试标准不一致,导致:

  • 插件实现时不敢只实现 IDataDriver(spec),而是 fallback 到 DriverInterface(core),漏掉协议方法,实际签名不合规。
  • 测试可被 as any 绕过类型不对齐,CI 测不出实现缺口。
  • 文档、代码和测试三分天下,生态长期不可持续。

主要分歧

  • DriverInterface(core)为最小集合,仅有 connect/disconnect + CRUD + bulk(共13方法),无 supports、upsert、stream、事务、schema 管理、explain等高级能力
  • IDataDriver(spec)为基础协议,28方法(含批量、schema、事务、explain、health、dropTable、capabilities、findStream等)
  • 两者都是"权威",但所有驱动实际只实现 core 导致协议缺口大量潜伏

推荐修复方案

  1. 单一权威: 明确以 spec 仓库的 IDataDriver 为唯一强制标准,彻底弃用 core/DriverInterface,所有插件以此为唯一实现合同
  2. 完整对齐: 用 Zod Schema + TS interface 驱动,制定签名类型约束不可落空
  3. 接口整合: 如果有历史兼容诉求,拆为"MinimalDriver"+"SpecDriver",但 CI 和主流插件只测试 SpecDriver
  4. 协议检查工具: CI强制所有插件类型匹配 IDataDriver,否则构建/测试禁止通过
  5. 清理 legacy fallback: 删除 driver-sql/driver-memory 里对旧协议 key 的容错逻辑 (filters/sort/skip etc),全部只认标准 key

优先级与影响

  • 优先级:P0(架构层面红线)
  • 影响范围: 所有 Driver 插件实现、协议文档、核心用例、内核注册机制
  • 影响版本: v3.x/v4.x

期望产出

  • 技术决策:统一标准接口与实现
  • 签名重构 PR
  • 插件/内核/测试/文档同步更新

Request Review

- Make DriverInterface a deprecated type alias for IDataDriver in spec/contracts
- Remove standalone DriverInterface from core (re-exports from spec)
- Add IDataDriver to core re-exports for direct import
- Update InMemoryDriver to implement IDataDriver with full DriverCapabilities
- Update SqlDriver to implement IDataDriver with missing methods:
  findStream, upsert, bulkUpdate, bulkDelete, commit, rollback, dropTable, explain
- Align supports objects with complete DriverCapabilities schema
- Update tests to match new contract (updateMany/deleteMany return number)

Fixed in c9c1c51. The build errors were caused by two issues:

  1. QueryInput vs QueryAST — All public driver method signatures (find, findOne, findStream, count, updateMany, deleteMany) were using QueryInput (Zod input type) instead of QueryAST (Zod inferred type) as required by the IDataDriver interface.
  2. Return type mismatchupdateMany/deleteMany in InMemoryDriver returned { count: number } instead of number.

Both @objectstack/driver-memory and @objectstack/driver-sql now build and pass all tests (94 + 72 tests).

Fixed in edddf61. The IDataDriver contract uses Record<string, unknown> for create/update/updateMany data parameters, but HookContext.input is typed as Record<string, unknown> (from Zod), making .data resolve to unknown. Added explicit as Record<string, unknown> casts at the 3 call sites in engine.ts (lines 901, 952, 955). All 4 affected packages now build and pass tests.

Pull request overview

Unifies the codebase around a single authoritative data driver contract (IDataDriver in @objectstack/spec/contracts) by deprecating DriverInterface as an alias and aligning driver implementations/tests/docs to the expanded contract.

Changes:

  • Deprecates DriverInterface and re-exports the unified contract from core/spec for backward-compatible imports.
  • Updates driver-sql and driver-memory to implement IDataDriver (methods + supports capability descriptor) and aligns return types (updateMany/deleteManynumber, deleteboolean).
  • Updates tests/docs/changelog to reflect the unified contract and updated method shapes.

bulkCreate currently inserts raw data and returns the database response without applying the same ID normalization and SQLite JSON/boolean serialization used by create() (formatInput/formatOutput). Under the IDataDriver contract, bulkCreate should return records with id set and without leaking driver-specific formats; consider generating missing IDs per row and formatting input/output consistently (or delegating to create() / a shared helper).

Suggested change
return await builder.insert(data).returning('*');
// Normalize IDs and apply driver-specific input formatting per row.
const ids: Array<string | number> = [];
const rowsToInsert = data.map((row) => {
const { _id, ...rest } = row || {};
const toInsert: Record<string, any> = { ...rest };
if (_id !== undefined && toInsert.id === undefined) {
toInsert.id = _id;
} else if (toInsert.id === undefined) {
toInsert.id = nanoid(DEFAULT_ID_LENGTH);
}
ids.push(toInsert.id);
const formatted = this.formatInput(object, toInsert);
if (this.tablesWithTimestamps.has(object)) {
if (this.isSqlite) {
const now = new Date().toISOString().replace('T', ' ').replace('Z', '');
formatted.created_at = now;
formatted.updated_at = now;
} else {
const nowFn = this.knex.fn.now();
formatted.created_at = nowFn;
formatted.updated_at = nowFn;
}
}
return formatted;
});
let inserted: any[];
if (this.isSqlite) {
// SQLite does not reliably support .returning('*') on INSERT.
await builder.insert(rowsToInsert);
inserted = await this.getBuilder(object, options).whereIn('id', ids).select('*');
} else {
inserted = await builder.insert(rowsToInsert).returning('*');
}
return inserted.map((row) => this.formatOutput(object, row) || row);

updateMany updates with the raw data object, but update() applies formatInput() (SQLite JSON serialization) and timestamp handling. For consistency and correctness (especially on SQLite JSON fields), updateMany should format/sanitize the update payload the same way as update() before calling builder.update().

Suggested change
const count = await builder.update(data);
const formattedData = this.formatInput(object, data, options);
const count = await builder.update(formattedData);

The engine test mocks are still using a capabilities property and casting as unknown as IDataDriver, which bypasses the unified contract this PR is trying to enforce. Update these mocks to provide the required supports field (and any required methods you rely on) and avoid the double-cast so the test suite actually catches interface drift.

Same issue for the second driver mock: it uses capabilities and relies on as unknown as IDataDriver, so the test won’t detect missing required IDataDriver members like supports, checkHealth, etc. Prefer a properly shaped mock (or a minimal factory) that conforms to IDataDriver without unsafe casts.
