# CHANGELOG
## v1.0.0
- **初始化重构迁移**: 剥离自 `knowbase/internal/db` 作为纯净独立包。
- **动态 Schema 管理**: 保留动态解析与同步，并封装独立的缓存与 Hook 事件触发逻辑。
- **权限隔离体系**: 通过 `Auth(userID)` 方法引入多维度的数据隔离层，`SystemUserID` 下退化为超管权限操作全域数据。

# apigo.cc/go/tableDB
`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。
## 使用指南
### 1. 初始化与 Auth
```go
package main
import (
"apigo.cc/go/tableDB"
"apigo.cc/go/log"
)
func main() {
app := tableDB.GetDB("sqlite://local.db", log.DefaultLogger)
// 在需要忽略权限的系统级后台执行时：
systemApp := app.Auth(tableDB.SystemUserID)
// 在特定的业务上下文执行时，将强制携带 creator 约束
userApp := app.Auth("user_12345")
}
```
### 2. DSL 动态表声明与同步
`TableDB` 提供底层隐藏表机制自动补全如 `id` 和 `autoIndex`，可用于初始化表结构。
```go
schema := `
== UserGroup ==
users SD
name v50 U
age i
`
_ = app.SyncSchema(schema)
```
### 3. 生命周期 Hooks 订阅
通过注册 Hooks，我们可以在发生元数据变更或行更新时进行回调拦截：
```go
app.Hooks.OnUpdatingRow = func(tableName string, row map[string]any) error {
if tableName == "users" {
row["modifiedAt"] = time.Now().Unix()
}
return nil
}
```
### 4. 动态表增删改查
底层调用与 `go/db` 使用习惯对齐，不同点是操作会被权限或 Hook 钩子影响：
```go
// 设定数据，如 ID 缺省会自动生成 c10 ID
_ = userApp.Table("users").Set(map[string]any{"name": "Alice"})
// 读取
record, _ := userApp.Table("users").Get("u1xxxx")
// 统计
count, _ := userApp.Table("users").Count(map[string]any{"age >": 20})
```

# 测试报告
## 覆盖场景
1. **结构化数据操作与隔离**
- 测试通过了包含和排除 system userID 时的增删改查。
- `Auth` 方法通过携带不同 userID 后实现了 `creator` 的数据隔离限制。
2. **生命周期 Hook 触发机制**
- `OnUpdatingRow` 触发并允许修改将要入库的行数据。
- `OnUpdatedRows` 在更新结束后被触发。
- `OnRemovedRows` 在成功移除后被触发返回对应的 ID 集合。
3. **SQL注入黑盒测试**
- Table 名称注入被验证并阻止。
- Field 查询字段注入被验证并阻止。
- Join On 条件验证被拦截。
- OrderBy 查询的语句结构注入被拦截。
## 性能测试
* 待核心 DB 层修复后回归测试性能。
