**内存展平技术**: 引入 `SchemaCache` 策略展平算法，支持无限深度的用户权限继承（如 `Manager -> Boss`），并将复杂权限图谱在内存中转换为 O(1) 的平滑映射，彻底消除运行时递归与 N+1 数据库查询。 + - **1-RTT 动态 SQL 注入**: 重构 `checkAuth` 与 `appendAuthAndConstraint`，将行级过滤条件（RLS）直接下推至 SQL WHERE 子句中。无论是 `Get`, `List` 还是 `Remove`，所有权限校验均与业务查询合并执行，确保极致性能。 + - **Opt-in 行级安全**: `_Table` 增加 `enableRLS` 开关。仅在显式开启的表上执行权限拦截，避免普通表（如字典表、日志表）产生不必要的计算开销。 +- **全新策略管理 API**: + - 新增 `SetPolicy` 与 `ListPolicy` 接口，支持标准化的 ABAC 策略配置（SQL 条件、参数绑定）。 + - **权限分级管理**: 实现了自主授权逻辑。普通用户仅在拥有目标表 `full` 权限时方可为他人分配该表权限；`inherit` 类高阶策略仅限 `SystemUserID` 操作。 +- **极致性能与校验**: + - **O(1) 字段验证**: 增加 `ValidFieldsMap` 缓存，消除 `buildQuery` 过程中高频的 Map 构建开销。 + - **防死锁与容错**: 权限继承逻辑内置环状检测，自动忽略 `A -> B -> A` 式的逻辑死循环。 +- **文档与工程化**: + - 全面重写 `README.md`，以 AI 驱动开发为中心，提供了清晰的 Schema 与 Policy 使用示例。 + - 同步更新 `.profile/README.md`，对齐基础设施版本索引。 + +## v1.1.5 (2026-05-14) +- **强制身份校验模型**: 重构 `GetDB` 返回类型为 `*TableDBUnauthorized`，在编译期强制要求必须先调用 `Auth` 后才能执行后续数据表操作。 +- **自定义元数据扩展**: 在系统表 `_Table` 和 `_Field` 中增加了 `settings` (JSON) 字段，业务方可通过 `TableSchema` 和 `FieldSchema` 存储自定义的表级或字段级配置。 +- **Schema API 正规化**: 引入了完整的 `TableSchema` 结构体，并将 `SetTable` 和 `RemoveTable` API 上提至 `TableDB` 层级。彻底废弃并移除了遗留的 `Table("xxx:Schema")` 魔法后缀调用方式。 +- **底层行为一致性**: `SetTable`, `RemoveTable`, `SetField`, `RemoveField` 现已彻底改写为底层封装调用 `Table("_Table")` 和 `Table("_Field")` 的 `Set/Remove` 方法，确保了系统自动更新的时间戳(`createTime`)、操作人(`creator`)及各种 Hook 生命周期事件能够被 100% 一致地触发。 + +## v1.1.4 (2026-05-14) +- **API 语义优化**: + - `Query` 方法从 `TableDB` 移动到 `Table` 对象，更符合面向对象调用习惯；`QueryRequest` 移除 `Table` 字段。 + - 移除 `App` 类型别名，统一使用 `TableDB`。 + - `SyncSchema` 改为私有方法 `syncSchema`，外部调用统一通过 `SetTable` 和 `SetField` 进行结构维护。 +- **结构维护增强**: + - 新增 `SetTable(memo)` 用于设置表元数据。 + - `SetField` 参数从 `any` 改为强类型的 `FieldSchema` 切片，并自动忽略 `CreateTime` 等系统字段，增强类型安全性。 + - `SetField` 在创建新表时会自动补全 `id` 字段的元数据，确保查询验证一致性。 + - 新增 `Tables()` 方法，支持列出当前用户有权访问的所有数据表。 +- **安全性完善**: + - 强化了所有公共 API 的 Auth 检查，确保未授权实例无法执行任何操作。 + - 内部 `buildQuery` 现在需要明确传入表名，增强了多表操作时的上下文隔离。 +- **测试回归**: 完全重构了测试用例，所有业务表创建均通过 `SetField` 接口完成，验证了公共 API 的闭环能力。 + +## v1.1.3 (2026-05-14) +- **API 统一与简化**: 引入 `SetField` 和 `RemoveField` 接口，支持通过统一的 Table API 动态管理表结构，实现了“操作表结构像操作数据一样简单”。 +- **批量操作支持**: `Set`, `Remove`, `SetField`, `RemoveField` 全面支持变长参数（Variadic arguments），显著提升了批量数据处理效率。 +- **安全性增强**: + - `GetDB` 返回实例默认未授权，强制调用 `Auth` 进行身份绑定。 + - `GetRawDB` (原 `Base`) 现已增加权限校验，仅限 `_system` 身份访问。 + - `Query` (App 级) 现已自动集成行级权限过滤。 +- **性能与稳定性**: 优化了元数据同步流程，合并批量操作后的 Schema 重建；修复了 `Cache.Load` 在并发调用时的死锁隐患。 +- **文档完善**: 重新编写了 README.md，完全抹除了实现细节，侧重于纯粹的 API 指南与最佳实践。 + +## v1.1.2 (2026-05-14) +- **文档重构**: 重新编写 README.md，以 AI 为中心，侧重于 API 功能说明与使用指南，移除了无关的实现细节。 +- **命名规范对齐**: 消灭了所有 Struct 中的 `json` tag，全面对齐驼峰命名规范，利用 `cast` 库自动处理大小写转换。 +- **API 完整性**: 基于 `getExports` 工具补全了 API 文档，涵盖了常量、全局变量及完整的 Table 操作接口。 + +## v1.1.1 (2026-05-14) +- **基础设施对齐**: 深度对接 `@go/db` 的自动 ID 生成器 (`NextID`) 与版本管理特性。 +- **元数据模型对齐**: 重构 `FieldSchema` 结构体，对齐 `_Field` 表物理结构，并统一使用 `cast.Convert` 进行 JSON 兼容的类型转换。 +- **查询安全性强化**: 增强 `BuildQuery` 的标识符验证与自动转义（Backticks），防止潜在的 SQL 注入风险。 +- **Schema 同步健壮性**: 优化 `reconstructAndSyncSchema` 与 `SyncSchema` 的元数据采集逻辑，支持更复杂的 DSL 结构。 + ## v1.1.0 - **内置系统架构 (SystemSchema)**: `_Table`, `_Field`, `_Policy` 等核心元数据表现已内置，`SyncSchema` 会在启动时自动补齐，无需在业务 DSL 中显式定义。 - **自动化 Schema 修复**: 修复了通过 API 创建表时缺少 `id` 字段导致的同步失败问题；`reconstructAndSyncSchema` 现在会自动为所有表补齐 `id c10 PK` 主键。 diff --git a/README.md b/README.md index 65f0fca..89c9f97 100644 --- a/README.md +++ b/README.md @@ -1,68 +1,102 @@ -# apigo.cc/go/tableDB +# go/tableDB v1.1.6 -`tableDB` 是建立在 `apigo.cc/go/db` 基础上的更高层抽象工具库。提供对于动态表、数据权限隔离和 Hook 的生命周期追踪管理。 +`tableDB` 是基于 `@go/db` 的高级数据库抽象引擎，支持动态 Schema 管理、身份驱动的行级隔离 (RLS) 以及 ABAC 权限策略。 -## 使用指南 +## 🎯 核心设计理念 +- **动态 Schema**: 像操作数据一样操作表和字段，无需手动 SQL 迁移。 +- **身份驱动**: 所有操作强制绑定 `userID`，系统自动处理 `creator` 和 `createTime`。 +- **ABAC 权限模型**: 支持 SQL 条件过滤、属性权限及关系继承，替代传统的 Role 体系。 +- **极速性能**: 通过内存展平策略实现零 RTT 鉴权，支持 O(1) 字段验证。 -### 1. 初始化与 Auth +## 📦 安装 +```bash +go get apigo.cc/go/tableDB +``` +## 🛠 API 指南 + +### 1. 初始化与授权 ```go -package main +// 获取未授权实例 (无法直接操作数据) +unauth := tableDB.GetDB("sqlite://data.db", logger) -import ( -
