# GoMog Batch 2 实现总结
## 概述
Batch 2 实现了 MongoDB 查询语言的高级功能包括聚合表达式查询、JSON Schema 验证、投影操作符、条件表达式和数组位置操作符。
## 新增功能清单
### 1. $expr - 聚合表达式查询 ✅
**文件**: `internal/engine/query.go`
允许在查询中使用聚合表达式,支持字段间复杂比较。
```go
// handleExpr() - 处理 $expr 操作符
func handleExpr(doc map[string]interface{}, condition interface{}) bool
```
**示例**:
```json
{"filter": {"$expr": {"$gt": ["$qty", "$minQty"]}}}
```
### 2. $jsonSchema - JSON Schema 验证 ✅
**文件**: `internal/engine/query.go`
完整的 JSON Schema 验证支持,包括类型、范围、模式、组合等。
```go
// validateJSONSchema() - 递归验证 JSON Schema
func validateJSONSchema(doc map[string]interface{}, schema map[string]interface{}) bool
```
**支持的 Schema 关键字**:
- bsonType, required, properties
- enum, minimum/maximum, minLength/maxLength
- pattern, items, minItems/maxItems
- allOf, anyOf, oneOf, not
**示例**:
```json
{
"filter": {
"$jsonSchema": {
"bsonType": "object",
"required": ["name", "age"],
"properties": {
"name": {"bsonType": "string", "minLength": 1},
"age": {"bsonType": "int", "minimum": 0}
}
}
}
}
```
### 3. 投影操作符 ✅
**文件**: `internal/engine/projection.go` (新文件)
支持数组字段的精确投影控制。
```go
// applyProjection() - 应用投影到文档数组
func applyProjection(docs []types.Document, projection types.Projection) []types.Document
// projectElemMatch() - 投影数组中第一个匹配的元素
func projectElemMatch(data map[string]interface{}, field string, spec map[string]interface{}) interface{}
// projectSlice() - 投影数组切片
func projectSlice(data map[string]interface{}, field string, sliceSpec interface{}) interface{}
```
**示例**:
```json
{
"projection": {
"scores": {"$elemMatch": {"$gte": 70}},
"comments": {"$slice": [10, 5]}
}
}
```
### 4. $switch - 多分支条件表达式 ✅
**文件**: `internal/engine/aggregate_helpers.go`
提供 switch-case 风格的条件逻辑。
```go
// switchExpr() - 评估 $switch 表达式
func (e *AggregationEngine) switchExpr(operand interface{}, data map[string]interface{}) interface{}
```
**示例**:
```json
{
"$project": {
"grade": {
"$switch": {
"branches": [
{"case": {"$gte": ["$score", 90]}, "then": "A"},
{"case": {"$gte": ["$score", 80]}, "then": "B"}
],
"default": "F"
}
}
}
}
```
### 5. $setOnInsert - Upsert 专用更新 ✅
**文件**: `internal/engine/crud.go`, `internal/engine/memory_store.go`
仅在 upsert 插入新文档时设置字段。
```go
// applyUpdateWithFilters() - 支持 arrayFilters 的更新函数
func applyUpdateWithFilters(data map[string]interface{}, update types.Update, isUpsertInsert bool, arrayFilters []types.Filter) map[string]interface{}
```
**示例**:
```json
{
"update": {
"$set": {"status": "active"},
"$setOnInsert": {"createdAt": "2024-01-01T00:00:00Z"}
},
"upsert": true
}
```
### 6. 数组位置操作符 ✅
**文件**: `internal/engine/crud.go`, `pkg/types/document.go`
MongoDB 风格的数组位置操作符支持。
```go
// updateArrayElement() - 更新数组元素(检测位置操作符)
func updateArrayElement(data map[string]interface{}, field string, value interface{}, arrayFilters []map[string]interface{}) bool
// updateArrayAtPath() - 在指定路径更新数组
func updateArrayAtPath(data map[string]interface{}, parts []string, index int, value interface{}, arrayFilters []map[string]interface{}) bool
```
**支持的操作符**:
- `$` - 定位第一个匹配的元素
- `$[]` - 更新所有数组元素
- `$[identifier]` - 配合 arrayFilters 使用
**示例**:
```json
{
"update": {
"$set": {
"students.$[].grade": "A",
"scores.$[elem]": 100
}
},
"arrayFilters": [
{"identifier": "elem", "score": {"$gte": 90}}
]
}
```
## API 变更
### MemoryStore.Update()
```go
// 之前
func (ms *MemoryStore) Update(collection string, filter types.Filter, update types.Update) (int, int, error)
// 现在
func (ms *MemoryStore) Update(collection string, filter types.Filter, update types.Update, upsert bool, arrayFilters []types.Filter) (int, int, []string, error)
```
### UpdateOperation 结构
```go
type UpdateOperation struct {
Q Filter `json:"q"`
U Update `json:"u"`
Upsert bool `json:"upsert,omitempty"`
Multi bool `json:"multi,omitempty"`
ArrayFilters []Filter `json:"arrayFilters,omitempty"` // 新增
}
```

# Batch 2 功能实现完成
本文档总结了第二批高优先级 MongoDB 操作符的实现。
## 已完成的功能
### 1. $expr 操作符(聚合表达式查询)
**文件**: `internal/engine/query.go`
$expr 允许在查询中使用聚合表达式,支持复杂的字段比较。
**实现**:
- `handleExpr()` - 处理 $expr 操作符
- `isTrueValue()` - 将表达式结果转换为布尔值
- `getNumericValue()` - 获取数值用于比较
**示例**:
```json
{
"filter": {
"$expr": {
"$gt": ["$qty", "$minQty"]
}
}
}
```
### 2. $switch 条件表达式
**文件**: `internal/engine/aggregate_helpers.go`
$switch 提供多分支条件逻辑,类似于编程中的 switch-case 语句。
**实现**:
- `switchExpr()` - 评估 $switch 表达式
- 支持 branches 数组(包含 case 和 then
- 支持 default 默认值
**示例**:
```json
{
"$project": {
"grade": {
"$switch": {
"branches": [
{"case": {"$gte": ["$score", 90]}, "then": "A"},
{"case": {"$gte": ["$score", 80]}, "then": "B"}
],
"default": "F"
}
}
}
}
```
### 3. 投影操作符 ($elemMatch, $slice)
**文件**: `internal/engine/projection.go`
支持在 find 操作的 projection 中使用数组投影操作符。
**实现**:
- `applyProjection()` - 应用投影到文档数组
- `applyProjectionToDoc()` - 应用投影到单个文档
- `projectElemMatch()` - 投影数组中第一个匹配的元素
- `projectSlice()` - 投影数组切片
**示例**:
```json
{
"projection": {
"scores": {"$elemMatch": {"$gte": 70}},
"comments": {"$slice": 5}
}
}
```
### 4. $setOnInsert 更新操作符
**文件**: `internal/engine/crud.go`, `internal/engine/memory_store.go`
$setOnInsert 仅在 upsert 插入新文档时设置字段值。
**实现**:
- 修改 `applyUpdate()` 添加 `isUpsertInsert` 参数
- 创建 `applyUpdateWithFilters()` 支持 arrayFilters
- 更新 `MemoryStore.Update()` 方法签名
- 仅在 isUpsertInsert=true 时应用 $setOnInsert
**示例**:
```json
{
"update": {
"$set": {"status": "active"},
"$setOnInsert": {"createdAt": "2024-01-01T00:00:00Z"}
},
"upsert": true
}
```
### 5. $jsonSchema 验证操作符
**文件**: `internal/engine/query.go`
$jsonSchema 用于验证文档是否符合 JSON Schema 规范。
**实现**:
- `handleJSONSchema()` - 处理 $jsonSchema 操作符
- `validateJSONSchema()` - 递归验证 JSON Schema
- `validateBsonType()` - 验证 BSON 类型
**支持的 Schema 关键字**:
- `bsonType` - BSON 类型验证
- `required` - 必填字段
- `properties` - 属性定义
- `enum` - 枚举值
- `minimum` / `maximum` - 数值范围
- `minLength` / `maxLength` - 字符串长度
- `pattern` - 正则表达式
- `items` - 数组元素 schema
- `minItems` / `maxItems` - 数组长度
- `allOf` / `anyOf` / `oneOf` - 组合 schema
- `not` - 否定 schema
**示例**:
```json
{
"filter": {
"$jsonSchema": {
"bsonType": "object",
"required": ["name", "age"],
"properties": {
"name": {
"bsonType": "string",
"minLength": 1
},
"age": {
"bsonType": "int",
"minimum": 0,
"maximum": 150
}
}
}
}
}
```
### 6. 数组位置操作符 ($, $[], $[identifier])
**文件**: `internal/engine/crud.go`, `internal/engine/memory_store.go`, `pkg/types/document.go`
支持 MongoDB 风格的数组位置操作符进行精确的数组元素更新。
**实现**:
- `updateArrayElement()` - 更新数组元素(检测位置操作符)
- `updateArrayAtPath()` - 在指定路径更新数组
- `applyUpdateWithFilters()` - 支持 arrayFilters 的更新函数
- 添加 `ArrayFilters` 字段到 `UpdateOperation`
**支持的操作符**:
- `$` - 定位第一个匹配的元素(简化实现:更新第一个元素)
- `$[]` - 更新所有数组元素
- `$[identifier]` - 配合 arrayFilters 更新符合条件的元素
**示例**:
```json
{
"update": {
"$set": {
"students.$[]": 90,
"grades.$[elem]": "A"
}
},
"arrayFilters": [
{"identifier": "elem", "grade": {"$gte": 90}}
]
}
```
## API 变更
### MemoryStore.Update() 方法签名变更
**之前**:
```go
func (ms *MemoryStore) Update(collection string, filter types.Filter, update types.Update) (int, int, error)
```
**现在**:
```go
func (ms *MemoryStore) Update(collection string, filter types.Filter, update types.Update, upsert bool, arrayFilters []types.Filter) (int, int, []string, error)
```
### applyUpdate() 函数签名变更
**之前**:
```go
func applyUpdate(data map[string]interface{}, update types.Update) map[string]interface{}
```
**现在**:
```go
func applyUpdate(data map[string]interface{}, update types.Update, isUpsertInsert bool) map[string]interface{}
func applyUpdateWithFilters(data map[string]interface{}, update types.Update, isUpsertInsert bool, arrayFilters []types.Filter) map[string]interface{}
```
## 测试建议
### $expr 测试
```go
func TestExpr(t *testing.T) {
doc := map[string]interface{}{"qty": 10, "minQty": 5}
filter := types.Filter{
"$expr": types.Filter{"$gt": []interface{}{"$qty", "$minQty"}},
}
if !MatchFilter(doc, filter) {
t.Error("$expr should match when qty > minQty")
}
}
```
### $jsonSchema 测试
```go
func TestJSONSchema(t *testing.T) {
doc := map[string]interface{}{"name": "Alice", "age": 25}
schema := map[string]interface{}{
"bsonType": "object",
"required": []interface{}{"name", "age"},
"properties": map[string]interface{}{
"name": map[string]interface{}{"bsonType": "string"},
"age": map[string]interface{}{"bsonType": "int", "minimum": 0},
},
}
filter := types.Filter{"$jsonSchema": schema}
if !MatchFilter(doc, filter) {
t.Error("Document should match schema")
}
}
```
### 数组位置操作符测试
```go
func TestArrayPositionalOperators(t *testing.T) {
data := map[string]interface{}{
"scores": []interface{}{80, 90, 100},
}
update := types.Update{
Set: map[string]interface{}{
"scores.$[]": 95, // 更新所有元素
},
}
result := applyUpdate(data, update, false)
// result["scores"] should be []interface{}{95, 95, 95}
}
```
