This method performs raw assignment WITHOUT + * change tracking, dirty marking, or equality checks. + * + * Business code MUST use updateXxx() methods instead. + */ + @FrameworkInternal("Business code must use updateXxx() methods") + public void __internalSet(String property, Object value) { + switch (property) { + case "id": this.id = (Long) value; break; + case "version": this.version = (Long) value; break; + default: + throw new IllegalArgumentException( + typeName() + " has no property: " + property); + } + } + + /** + * Framework-internal generic property read channel. + * + * Used by serializers, diff engines, and audit trail builders for + * reflection-free, uniform property access on BaseEntity references. + */ + @FrameworkInternal("Business code should use typed getXxx() methods") + public Object __internalGet(String property) { + switch (property) { + case "id": return this.id; + case "version": return this.version; + default: + throw new IllegalArgumentException( + typeName() + " has no property: " + property); + } + } +} +``` + +### 3.2 Generated Entity (e.g. Task) + +Each generated entity overrides both `__internalSet` and `__internalGet` with its own switch branches. +All `setXxx()` methods are removed. `updateXxx()` methods assign fields directly. + +```java +public class Task extends BaseEntity { + private String name; + private TaskStatus status; + private Platform platform; + private LocalDateTime createTime; + private LocalDateTime updateTime; + private SmartList taskLogList; + + // ===== Public API: Getters ===== + public String getName() { return name; } + public TaskStatus getStatus() { return status; } + public Platform getPlatform() { return platform; } + public LocalDateTime getCreateTime() { return createTime; } + public LocalDateTime getUpdateTime() { return updateTime; } + public SmartList getTaskLogList() { return taskLogList; } + + // ===== Public API: Update (with change tracking) ===== + public Task updateName(String name) { + name = StrUtil.trim(name); + if (ObjectUtil.equal(this.name, name)) return this; + handleUpdate(NAME_PROPERTY, getName(), name); + this.name = name; // Direct field assignment, no setter + return this; + } + + public Task updateStatus(TaskStatus status) { + if (ObjectUtil.equal(this.status, status)) return this; + handleUpdate(STATUS_PROPERTY, getStatus(), status); + this.status = status; // Direct field assignment + return this; + } + + // ... other updateXxx methods follow the same pattern + + // ===== Framework Internal: Generated switch dispatch ===== + @Override + @FrameworkInternal + public void __internalSet(String property, Object value) { + switch (property) { + case "name": this.name = (String) value; break; + case "status": this.status = (TaskStatus) value; break; + case "platform": this.platform = (Platform) value; break; + case "createTime": this.createTime = (LocalDateTime) value; break; + case "updateTime": this.updateTime = (LocalDateTime) value; break; + case "taskLogList": this.taskLogList = (SmartList) value; break; + default: super.__internalSet(property, value); + } + } + + @Override + @FrameworkInternal + public Object __internalGet(String property) { + switch (property) { + case "name": return this.name; + case "status": return this.status; + case "platform": return this.platform; + case "createTime": return this.createTime; + case "updateTime": return this.updateTime; + case "taskLogList": return this.taskLogList; + default: return super.__internalGet(property); + } + } + + // NO setXxx methods generated +} +``` + +### 3.3 Key Design Decisions + +**Why generated switch/if-else instead of reflection?** + +TeaQL is a code generation framework. We have full knowledge of every entity's properties at +generation time. Generating explicit switch branches is: +- **Zero reflection overhead**: Each case is a direct field assignment (`putfield` bytecode). + No `Method.invoke()`, no `Field.setAccessible()`, no `MethodHandle` lookup. +- **JVM-optimized**: The JVM compiles String switch into a `hashCode()` + `equals()` lookup table, + which is O(1) in practice. +- **Compile-time verifiable**: Typos in property names or type mismatches are caught during + code generation, not at runtime. +- **Android-friendly**: Avoids reflection performance penalties on ART/Dalvik and sidesteps + Android's strict reflection access restrictions. + +**Why `updateXxx` uses direct field assignment instead of calling `__internalSet`?** + +`updateXxx()` is in the same class as the field. It can assign `this.name = name` directly. +Routing through `__internalSet` would add an unnecessary String switch lookup and bypass the +change tracking that `updateXxx` has already performed. The two paths serve fundamentally +different purposes: + +| Path | Change Tracking | Dirty Mark | Equality Check | Purpose | +|------|:-:|:-:|:-:|---------| +| `updateXxx()` | ✅ | ✅ | ✅ | Business mutation | +| `__internalSet()` | ❌ | ❌ | ❌ | Object assembly from DB/JSON | + +**Why `__internalSet` is `public` instead of `protected` or package-private?** + +Framework infrastructure code (database hydrators, JSON modules) lives in packages like +`io.teaql.runtime` or `io.teaql.core.sql.portable`, which are in different packages from +generated entities (e.g. `com.doublechaintech.xxx.task`). Java's `protected` and +package-private access modifiers cannot cross this package boundary for non-subclass callers. + +Making `__internalSet` public is acceptable because **its API surface is intentionally hostile +to casual use**: +- **No type safety**: Parameters are `(String, Object)` — no IDE autocomplete for property names, no compile-time type checking. +- **No discoverability**: Developers looking for "how to set status" will find `updateStatus(TaskStatus)` in autocomplete, not `__internalSet("status", obj)`. +- **Naming signal**: The `internal` prefix and `@FrameworkInternal` annotation clearly communicate "do not use". + +Compare the two alternatives a developer would see: +```java +// Clean, typed, discoverable — the natural choice +task.updateStatus(newStatus); + +// Ugly, untyped, undiscoverable — screams "don't touch" +task.__internalSet("status", newStatus); +``` + +## 4. Impact on Existing Framework Code + +### 4.1 Entity.setProperty() and BeanUtil.setProperty() + +The existing `Entity` interface has a `setProperty(String, Object)` default method that +delegates to `BeanUtil.setProperty()`, which uses reflection to find and invoke `setXxx()` +methods, falling back to direct field access. + +With this design, `Entity.setProperty()` should be refactored to delegate to `__internalSet()`: + +```java +// Entity interface +default void setProperty(String propertyName, Object value) { + if (this instanceof BaseEntity) { + ((BaseEntity) this).__internalSet(propertyName, value); + } +} +``` + +This eliminates the dependency on `BeanUtil`'s reflection-based setter invocation for entity +property assignment. `BeanUtil.setProperty()` remains available for non-entity beans. + +### 4.2 BaseEntity.addRelation() + +`BaseEntity.addRelation()` currently calls `setProperty()`, which in turn calls `BeanUtil`. +After refactoring `setProperty()` to delegate to `__internalSet()`, `addRelation()` will +automatically benefit from the generated switch path with zero reflection. + +### 4.3 Database Hydrator (PortableSQLRepository / SqlDataServiceExecutor) + +The hydrator code that assembles entities from `ResultSet` rows should switch from +`entity.setXxx(value)` to `entity.__internalSet(propertyName, value)`. This is a straightforward +change since the hydrator already works with property names from `EntityDescriptor` metadata. + +### 4.4 JSON Serialization / Deserialization + +**Serialization (Entity → JSON)**: No change needed. Jackson uses public getters, which remain. + +**Deserialization (JSON → Entity)**: Requires a TeaQL-specific Jackson module or custom +deserializer that routes property assignment through `__internalSet()` instead of relying +on setter detection: + +```java +// TeaQL Jackson Module — core deserialization logic +@Override +public Object deserialize(JsonParser p, DeserializationContext ctxt) { + BaseEntity entity = createEntity(targetType); + while (p.nextToken() != JsonToken.END_OBJECT) { + String fieldName = p.getCurrentName(); + p.nextToken(); + Object value = parseValue(p, fieldName); + entity.__internalSet(fieldName, value); + } + return entity; +} +``` + +Alternatively, configure Jackson globally for field-level access: +```java +mapper.setVisibility(PropertyAccessor.FIELD, Visibility.ANY); +mapper.setVisibility(PropertyAccessor.SETTER, Visibility.NONE); +``` +This approach is simpler but less controlled. + +## 5. Three-Layer Defense Against Misuse + +Although `__internalSet` is technically callable from APP code, three layers of defense +ensure it is never used in practice: + +### 5.1 Layer 1: API Design (Passive Defense) + +The absence of `setXxx()` methods removes the obvious, typed, discoverable mutation path. +`__internalSet(String, Object)` is not type-safe, not auto-completable, and clearly +communicates "this is not for you". Developers will naturally gravitate toward `updateXxx()`. + +### 5.2 Layer 2: `@FrameworkInternal` Annotation (IDE Warning) + +```java +package io.teaql.core; + +import java.lang.annotation.*; + +/** + * Marks a method as framework-internal. Business code must not call methods + * annotated with @FrameworkInternal directly. + * + * IDE plugins and static analysis tools should flag any call to a + * @FrameworkInternal method from outside framework packages as an error. + */ +@Retention(RetentionPolicy.CLASS) +@Target({ElementType.METHOD, ElementType.CONSTRUCTOR}) +@Documented +public @interface FrameworkInternal { + /** Guidance message for developers who encounter this annotation. */ + String value() default "This method is for framework infrastructure use only."; +} +``` + +Integration points: +- **IntelliJ IDEA**: Custom inspection rule to flag calls to `@FrameworkInternal` methods. +- **Error Prone**: Custom `BugChecker` that reports `@FrameworkInternal` call sites as errors. +- **SpotBugs / PMD**: Custom detector for the annotation. + +### 5.3 Layer 3: Architecture Test (CI Hard Gate) + +Using ArchUnit (or equivalent) in the project's test suite: + +```java +@Test +void businessCodeMustNotCallInternalSet() { + noClasses() + .that().resideInAPackage("com.teaql.taskboard..") // APP layer + .should().callMethod(BaseEntity.class, "__internalSet", + String.class, Object.class) + .check(importedClasses); +} +``` + +This test runs in CI and fails the build if any APP-layer class calls `__internalSet`. +It is a **hard gate** — no exceptions, no overrides. + +## 6. Generator Change Summary + +| Generated Artifact | Before | After | +|--------------------|--------|-------| +| `public void setXxx(T value)` | Generated with `@Deprecated` | **Removed entirely** | +| `public T updateXxx(T value)` | Calls `setXxx(value)` internally | **Direct field assignment** (`this.field = value`) | +| `public void __internalSet(String, Object)` | Does not exist | **New**: generated switch/if-else per entity | +| `public Object __internalGet(String)` | Does not exist | **New**: generated switch/if-else per entity | +| `Entity.setId()` / `Entity.setVersion()` | `void setId(Long)` / `void setVersion(Long)` | **Replaced by** `updateId(Long)` / `updateVersion(Long)` on `BaseEntity` | +| `@FrameworkInternal` annotation | Does not exist | **New**: defined in `io.teaql.core` | + +## 7. Migration Path + +1. **Phase 1**: Add `__internalSet()` to `BaseEntity` and the `@FrameworkInternal` annotation + in `teaql-core`. This is backward-compatible — existing setters still work. + +2. **Phase 2**: Update the code generator to produce `__internalSet()` overrides in each entity. + Generate `updateXxx()` with direct field assignment. Stop generating `setXxx()` methods. + +3. **Phase 3**: Update framework infrastructure (`PortableSQLRepository`, `BeanUtil` path, + JSON modules) to use `__internalSet()` instead of setter invocation. + +4. **Phase 4**: Add ArchUnit tests in example projects. Remove any remaining `setXxx()` calls + from APP code. All APP mutation goes through `updateXxx()`, all infrastructure goes through + `__internalSet()`. + +## 8. Resolved Decisions + +1. **`__internalGet(String): Object` — YES, generate it.** + Each entity generates a symmetric `__internalGet` alongside `__internalSet`. This provides a + reflection-free, uniform generic read path for framework infrastructure (serializers, diff + engines, audit trail builders). Public getters remain the preferred API for typed access + in business code. + +2. **`Entity.setId()` / `Entity.setVersion()` — replace with `updateId()` / `updateVersion()`.** + The `Entity` interface will no longer declare `void setId(Long)` or `void setVersion(Long)`. + Instead, `BaseEntity` provides `updateId(Long)` and `updateVersion(Long)` which follow the + same pattern as all other `updateXxx()` methods: equality check, change tracking via + `handleUpdate()`, and direct field assignment. Framework infrastructure that needs to assign + id/version without change tracking (e.g. during hydration) uses `__internalSet("id", value)`. + + This change: + - Removes `setId` / `setVersion` from the `Entity` interface contract. + - Provides `updateId` / `updateVersion` on `BaseEntity` for business use (e.g. seed data). + - Routes framework hydration through `__internalSet`, consistent with all other properties. + +## 9. Remaining Open Question + +1. **Seed data initialization style.** + With `updateId(Long)` available on `BaseEntity`, seed data initialization can use the + standard business API: + ```java + Platform platform = new Platform(); + platform.updateId(1L) + .updateName("Android Local Platform") + .auditAs("Seed data") + .save(ctx); + ``` + This is cleaner than `__internalSet("id", 1L)` and fully participates in change tracking. + However, in bulk migration or import scenarios where change tracking is undesirable, + `__internalSet` remains available as the raw assignment path. The choice between the two + depends on whether the caller wants audit trail semantics. diff --git a/docs/2026-06-21-dynamic-fields-design.md b/docs/2026-06-21-dynamic-fields-design.md new file mode

`BaseEntity.additionalInfo` 的 JSON 行为由可选 `teaql-jackson` 模块提供，需要特别处理： + +- `BaseEntity` 本身不依赖 Jackson； +- 注册 `io.teaql.jackson.TeaQLModule` 后，`BaseEntityJsonSerializer` 只序列化 `id`、`version` 和

为 null 时静默丢弃**，不会存入 `additionalInfo`。因此不能用 `addDynamicProperty()` 表达"字段已加载但值为空"，`DynamicFieldValues` wrapper 必须自行处理 null 语义（参见 §3.2）。 + +因此 Dynamic Fields 不能把每个动态字段直接用原始 code 放进 `additionalInfo` 顶层。否则会出现三个问题： + +- 和普通临时动态属性冲突，例如 `_xxx` SQL 派生列； +- 和 UI/响应附加属性冲突，例如 action/style 类信息； +- 反序列化时无法区分“未知 JSON 字段”和“允许写入的 dynamic field”。 + +### 3.1 出站 JSON 形状 + +默认出站 JSON 推荐使用 `#` 扁平形状： + +```json +{ + "id": 1001, + "name": "Acme Platform", + "#customer_asset_no": "A-10086", + "#enabled_for_custom_flow": true, + "#priority_score": 80 +} +``` + +内部可以通过： + +```java +entity.addDynamicProperty(".#customer_asset_no", "A-10086"); +``` + +利用 `addDynamicProperty()` 的 `.` 前缀规则把 key 存为 `#customer_asset_no`，`BaseEntityJsonSerializer` 遍历 `additionalInfo` 时会输出顶层 `#customer_asset_no`。但不能输出： + +```json +{ + "_customer_asset_no": "A-10086" +} +``` + +也不能输出无前缀字段： + +```json +{ + "customer_asset_no": "A-10086" +} +``` + +原因是后两种形状无法稳定区分标准字段、临时动态属性、聚合动态属性和 dynamic field。 + +`#` 前缀的含义应固定为： + +```text +# = Dynamic Field value +``` + +它的好处是动态字段值仍然在业务对象第一层，前端表格、导入导出和调试时更直观；同时又不会和标准字段名冲突。 + +如果响应需要同时返回字段元数据，可以保留一个系统元信息 key。`__fieldMeta` 描述的是 response field metadata，不只是 dynamic field metadata；它的 key 必须和本次响应 JSON 顶层字段名一致： + +```json +{ + "id": 1001, + "name": "Acme Platform", + "#customer_asset_no": "A-10086", + "#enabled_for_custom_flow": true, + "#priority_score": 80, + "__fieldMeta": { + "id": { + "type": "ID", + "label": "ID", + "masked": false, + "selected": true, + "dynamic": false + }, + "name": { + "type": "STRING", + "label": "Name", + "masked": false, + "selected": true, + "dynamic": false + }, + "#customer_asset_no": { + "type": "STRING", + "label": "Customer Asset No", + "masked": false, + "selected": true, + "dynamic": true + }, + "#priority_score": { + "type": "NUMBER", + "label": "Priority Score", + "masked": false, + "selected": true, + "dynamic": true + } + } +} +``` + +`__fieldMeta` 是保留 key，不是动态字段值。字段编码不能以 `#` 或 `__` 开头。`__fieldMeta` 只描述本次响应中出现或被明确 select 的字段，不是完整字段定义表。 + +### 3.2 Null、未加载和脱敏 + +`#` 存在且值为 `null`，表示字段已加载但值为空： + +```json +{ + "#customer_asset_no": null +} +``` + +**实现注意：** `BaseEntity.addDynamicProperty()` 在 value 为 null 时静默返回，不会存入 `additionalInfo`。因此 `DynamicFieldValues` wrapper 不能依赖 `addDynamicProperty()` 来表达 null 值。推荐 `DynamicFieldValues` 使用 `BaseEntity.putAdditional()` 直接存入 `#: null`，或者 wrapper 自身维护已加载字段集合，序列化时由 wrapper 负责输出 null。 + +字段不存在，表示未 select 或当前用户不可见。业务代码读取未加载字段时应抛出： + +```text +DYNAMIC_FIELD_NOT_SELECTED +``` + +读取不可见字段时应抛出或按策略返回 masked 值： + +```text +DYNAMIC_FIELD_NOT_VISIBLE +``` + +如果需要携带更多元数据，可以使用 `__fieldMeta`，而不是把值改成对象： + +```json +{ + "#customer_asset_no": "A-10086", + "__fieldMeta": { + "#customer_asset_no": { + "value": "A-10086", + "type": "STRING", + "masked": false, + "selected": true, + "dynamic": true + }, + "name": { + "type": "STRING", + "masked": false, + "selected": true, + "dynamic": false + } + } +} +``` + +默认值仍保持在 `#` 上；`__fieldMeta` 面向管理后台、调试、导入导出和审计。 + +### 3.3 入站 JSON 形状 + +反序列化必须区分普通 unknown additional property 和动态字段写入。 + +允许的动态字段入站形状只应该是显式 `#` 前缀： + +```json +{ + "id": 1001, + "#customer_asset_no": "A-10086" +} +``` + +不允许把未知顶层字段自动解释为动态字段： + +```json +{ + "customer_asset_no": "A-10086" +} +``` + +原因： + +- 注册 `TeaQLModule` 后，`BaseEntityJsonDeserializer` 会把所有未知字段通过 `putAdditional()` 放入 `additionalInfo`； +- 如果 unknown field 自动写入 dynamic fields，会绕过字段定义、权限、类型、审计和 intent； +- 拼写错误的标准字段也可能被误写成动态字段。 + +入站 `#` 只能被解析为候选载荷，真正写入必须经过： + +```java +ctx.dynamicFields() +``` + +或应用服务显式调用的 dynamic field command handler。 + +普通 entity save 不应因为 JSON 中带了 `#` 就自动持久化动态字段，除非调用方进入明确的 dynamic-field write flow。 + +这个形状的主要影响： + +- `#` 必须成为 TeaQL JSON 的保留前缀，标准字段、普通 additional property、临时动态列都不能使用这个前缀； +- 注册 `TeaQLModule` 后，`BaseEntityJsonDeserializer` 会把 `#customer_asset_no` 通过 `putAdditional()` 收进 `additionalInfo`，但 repository save 不能自动写库； +- JSONPath、前端表单和导入导出工具访问字段时通常要使用 bracket 形式，例如 `$['#customer_asset_no']`； +- OpenAPI/Schema 不能只靠普通 Java Bean 属性表达，需要补充 dynamic-field 扩展 schema； +- `__fieldMeta` 必须作为保留元数据 key 特判，不参与动态字段值写入； +- 入站 JSON 中的 `__fieldMeta` 只能忽略或作为客户端提示，不能作为字段定义、权限、类型、加密或脱敏依据； +- 服务端最终仍以 `EntityDescriptor` 和 `DynamicFieldDef` 为准； +- `__` 前缀保留给 TeaQL 系统元信息，不能作为标准字段名、动态字段 code 或普通 additional property 前缀。 + +### 3.4 命名空间保留 + +建议保留以下顶层 JSON 名称，生成器不应生成同名标准字段： + +```text +# +__fieldMeta +``` + +建议保留以下 `additionalInfo` 内部命名空间： + +```text +# +__fieldMeta +``` + +已有的临时动态属性仍可继续使用当前规则： + +```text +_xxx +``` + +但 dynamic fields 不使用 `_xxx` 扁平命名，而使用 `#xxx` 扁平命名。 + +### 3.5 与其他动态属性的区分 + +建议把运行期附加信息分成三类语义： + +| 类别 | JSON 形状 | 来源 | 是否可反序列化写库 | +| --- | --- | --- | --- | +| SQL 临时动态列 | `_xxx` | `simpleDynamicProperties` | 否 | +| 聚合/增强动态属性 | `_xxx` 或业务约定名 | `dynamicAggregateAttributes` / enhancer | 否 | +| Dynamic Fields | `#` | `DynamicFieldsProvider` | 只能通过显式 dynamic field write flow | +| Response Field Meta | `__fieldMeta` | `EntityDescriptor` + `DynamicFieldsProvider` / facade | 否 | + +这个区分必须写入 AI Agent 和代码生成器指导：看到未知 JSON 字段时，不要自动把它当作 dynamic field；只有 `#` 前缀字段才进入 dynamic field 解析，且 `__fieldMeta` 是响应字段元数据保留字段。 + +## 4. 分层设计 + +### 4.1 `teaql-dynamic-fields-api` + +抽象契约层。只依赖 TeaQL core，不依赖 runtime、SQL、Spring 或具体 provider。 + +建议包含： + +```text +DF +DynamicFieldSelection +DynamicFieldFilter +DynamicFieldOrder +DynamicFieldQuery +DynamicFieldDef +DynamicFieldRef +DynamicOwnerRef +DynamicFieldScope +DynamicFieldValue +DynamicFieldValues +DynamicDataType +DynamicLogicalType +DynamicFieldStatus +DynamicFieldCapabilities +DynamicFieldsProvider +DynamicFieldContext +DynamicFieldException +``` + +关键原则： + +- API 层定义语义对象，不碰 `UserContext`； +- `DynamicFieldContext` 是轻量接口，由 runtime 适配； +- API 层不暴露具体动态字段表； +- filter/order 的对象模型可以先定义，但 MVP 不一定执行。 + +`DynamicFieldContext` 建议最小化： + +```java +public interface DynamicFieldContext { + String scopeType(); + String scopeId(); + String userId(); + String purpose(); + String comment(); + boolean strictIntent(); +} +``` + +`scopeType()` / `scopeId()` 用来表达字段定义和值归属的业务作用域。普通单体系统可以使用 `GLOBAL/default` 或 `APPLICATION/`；SaaS 系统可以使用 `TENANT/`；项目型系统可以使用 `PROJECT/`。 + +如果后续需要角色、部门、区域、数据域等信息，通过 capability 或扩展接口添加，不要一开始把 `UserContext` 整体泄漏到 api。 + +### 4.2 `teaql` + +当前仓库中 core/runtime 边界主要集中在 `teaql` 模块，`UserContext`、`Entity`、`BaseRequest`、`SearchRequest` 都在这里。 + +第一版建议只在 `teaql` 中增加最小桥接点： + +```text +BaseEntity.dynamicFields() +SearchRequest.getDynamicFieldSelection() +BaseRequest.selectDynamicFieldsWith(...) +``` + +`UserContext.dynamicFields()` 通过现有的 `capability()` 机制桥接，不需要在 `UserContext` 接口上新增抽象方法： + +```java +// UserContext 上添加 default 方法，委托给 capability +default DynamicFieldsFacade dynamicFields() { + DynamicFieldsFacade facade = capability(DynamicFieldsFacade.class); + if (facade == null) { + throw new TeaQLRuntimeException("DynamicFieldsFacade not registered"); + } + return facade.withContext(this); +} +``` + +这样 `teaql-core` 只需要知道 `DynamicFieldsFacade` 接口（定义在 `teaql-dynamic-fields-api` 中），不会引入 provider 或 runtime 依赖。 + +业务代码使用方式： + +```java +ctx.dynamicFields() + .purpose("Update dynamic field") + .owner("Platform", platformId) + .string("customer_asset_no") + .set("A-10086"); +``` + +facade 负责： + +- 从 `UserContext` 提取 scope/user/comment/purpose； +- enforce Triple-Intent； +- 校验 owner type 和 owner id； +- 查找字段定义； +- 校验类型、状态、可见/可编辑/可查询； +- 执行权限、隐私、mask； +- 调用 provider； +- 统一包装错误。 + +`SearchRequest.getDynamicFieldSelection()` 应作为接口方法声明在 `SearchRequest` 上，`BaseRequest` 提供具体实现（使用专用字段存储，不使用 `extensions` map）： + +```java +// SearchRequest 接口 +DynamicFieldSelection getDynamicFieldSelection(); + +// BaseRequest 实现 +private DynamicFieldSelection dynamicFieldSelection; + +public SearchRequest selectDynamicFieldsWith(DynamicFieldSelection selection) { + this.dynamicFieldSelection = selection; + return (SearchRequest) this; +} + +@Override +public DynamicFieldSelection getDynamicFieldSelection() { + return dynamicFieldSelection; +} +``` + +### 4.3 Generated Query + +Query DSL 里建议保留三个最终方法名： + +```java +selectDynamicFieldsWith(...) +filterByDynamicFieldsWith(...) +orderByDynamicFieldsWith(...) +``` + +但分期上只先实现： + +```java +selectDynamicFieldsWith(...) +``` + +原因： + +- select 可以 post-load，复杂度低； +- filter/order 会改变主 SQL query planning； +- filter/order 必须处理 join/exists、类型表、scope、field code 到 field id 的解析、排序 null 语义和索引策略； +- 过早实现容易把动态字段 SQL 细节泄漏到 core DSL。 + +MVP 查询示例： + +```java +Q.platformsWithMinimalFields() + .selectName() + .selectCreateTime() + .selectDynamicFieldsWith( + DF.fields() + .selectString("customer_asset_no") + .selectBool("enabled_for_custom_flow") + .selectNumber("priority_score") + ) + .comment("List platforms with dynamic fields") + .purpose("Load platform records and

中，`SQLRepository` 已经会把 `simpleDynamicProperties` 拼进 select，并在 mapper 里塞进 `Entity.addDynamicProperty()`。 + +MVP 阶段不要求 `teaql-sql` 直接理解 dynamic field filter/order。 + +推荐执行策略： + +1. 主 query 正常执行； +2. `UserContext.executeForList()` 或 repository enhance 阶段检测 request 的 `DynamicFieldSelection`； +3. 收集 owner ids； +4. 调用 `DynamicFieldsProvider.loadValues(ctx, ownerRefs, selection)`； +5. 把结果放入 entity 的 `.dynamicFieldValues` wrapper； +6. `entity.dynamicFields()` 提供类型化读取。 + +第二阶段再在 `teaql-sql` 加入 dynamic field filter/order planning。 + +## 5. Provider 契约 + +Provider 是底层实现接口，不做业务 facade。 + +第一版建议： + +```java +public interface DynamicFieldsProvider { + DynamicFieldDef loadFieldDef(DynamicFieldContext ctx, DynamicFieldRef ref); + + List listFieldDefs(DynamicFieldContext ctx, String ownerType); + + DynamicFieldValues loadValues( + DynamicFieldContext ctx, + DynamicOwnerRef ownerRef, + DynamicFieldSelection selection); + + Map loadValues( + DynamicFieldContext ctx, + List ownerRefs, + DynamicFieldSelection selection); + + void saveValue(DynamicFieldContext ctx, DynamicSetCommand command); + + void deleteValue(DynamicFieldContext ctx, DynamicValueRef valueRef); + + DynamicFieldCapabilities capabilities(); +} +``` + +暂缓放入第一版 provider 的方法： + +```java +DynamicQueryResult query(DynamicFieldContext ctx, DynamicFieldQuery query); +``` + +原因是 query 会暗含 filter/order/search/facet 能力，容易把第二阶段 SQL planner 的问题提前拉进 MVP。 + +第一版 capabilities： + +```text +sourceOfTruth +supportsTransaction +supportsBatchLoad +supportsTypedValue +supportsBasicPermission +supportsBasicAudit +``` + +第二阶段再加： + +```text +supportsFilter +supportsSort +supportsFacet +supportsFullText +supportsMasking +supportsAdvancedPermission +``` + +## 6. 数据模型 + +字段定义表： + +```text +dynamic_field_def +----------------- +id +scope_type +scope_id +owner_type +code +name +description +data_type +logical_type +required +visible +editable +filterable +sortable +searchable +exportable +importable +auditable +privacy_level +mask_rule +default_value +status +display_order +version +created_by +created_at +updated_by +updated_at +``` + +唯一约束： + +```text +scope_type + scope_id + owner_type + code +``` + +值表第一版按类型拆分： + +```text +dynamic_string_value +dynamic_number_value +dynamic_bool_value +dynamic_datetime_value +dynamic_enum_value +``` + +每张值表都应有： + +```text +id +scope_type +scope_id +owner_type +owner_id +field_id +value_* +version +created_by +created_at +updated_by +updated_at +``` + +唯一约束： + +```text +scope_type + scope_id + owner_type + owner_id + field_id +``` + +如果某个 provider 内部天然是多租户模型，可以把 `TENANT/` 映射为 `tenant_id` 或数据库分区字段；但 API 和设计层不应把 tenant 作为唯一作用域。 + +第一版明确不支持： + +- multi-value； +- per-field 多 provider 写入； +- dynamic field join 到标准 relation； +- 跨 owner type 查询； +- filter/order/search/facet； +- 字段定义热变更后自动迁移历史值。 + +## 7. 生命周期和错误模型 + +字段状态建议： + +```text +DRAFT +ACTIVE +DISABLED +DEPRECATED +DELETED +``` + +读取规则： + +- `ACTIVE` 可读； +- `DISABLED` 默认不可写，可按配置可读； +- `DEPRECATED` 可读可写由兼容策略决定，但创建新字段时不应推荐； +- `DELETED` 不参与普通查询，只保留审计和历史处理。 + +错误应使用稳定 code，方便 AI Agent 和前端处理： + +```text +DYNAMIC_FIELD_NOT_FOUND +DYNAMIC_FIELD_TYPE_MISMATCH +DYNAMIC_FIELD_NOT_SELECTED +DYNAMIC_FIELD_NOT_VISIBLE +DYNAMIC_FIELD_NOT_EDITABLE +DYNAMIC_FIELD_OWNER_TYPE_MISMATCH +DYNAMIC_FIELD_TENANT_MISMATCH +DYNAMIC_FIELD_PROVIDER_UNSUPPORTED +DYNAMIC_FIELD_INTENT_REQUIRED +``` + +如果字段未被 select 就读取： + +```text +Dynamic field customer_asset_no was not selected. +``` + +这应是明确错误，不应静默返回 null。真正的 null 值和未加载必须区分。 + +## 8. 分期 + +### Phase 1: Select + Read/Write MVP + +目标：能定义字段、写值、按 owner 批量读取、在主 query 后装载 selected dynamic fields。 + +范围： + +- `teaql-dynamic-fields-api`； +- `UserContext.dynamicFields()` facade； +- provider registry； +- TeaQL DB source-of-truth provider； +- `selectDynamicFieldsWith(...)`； +- `DynamicFieldValues` 返回 wrapper； +- 基础类型校验； +- 基础权限/可见/可编辑校验； +- comment/purpose enforcement； +- 审计字段落库。 + +验收示例： + +```java +ctx.dynamicFields() + .owner("Platform", platformId) + .string("customer_asset_no") + .set("A-10086");

All integration tests for DuckDB passed perfectly without any errors using a file-backed in-process database (`jdbc:duckdb:./test_duckdb.db`). DuckDB offers excellent compatibility with standard PostgreSQL syntax, which allows our framework to run seamlessly by leveraging `PortableSqlDialect` alongside a minor `` token hotfix. + +### Key Learnings +1. **In-Memory Volatility**: The `jdbc:duckdb:` URL (with no file path) creates a completely isolated database per `Connection`. To avoid tables disappearing across database operations when a connection closes, a file-backed URL like `jdbc:duckdb:test.db` should be used. +2. **VARCHAR Syntax**: DuckDB natively supports unbounded `VARCHAR` lengths. Standard SQL `VARCHAR(max)` is not recognized. The `DuckDataServiceExecutor` actively patches `` to `255` before execution, ensuring the syntax remains valid while meeting constraints. +3. **Pagination & Partitioning**: DuckDB smoothly handles `LIMIT/OFFSET` as well as complex analytic functions like `row_number() over(partition by ...)` without requiring special adaptations. + +## Test Results + +- **Data Insertion**: 🟢 Passed +- **Simple Query**: 🟢 Passed +- **Joins and Relations**: 🟢 Passed +- **Complex Aggregation (Group By / Facet)**: 🟢 Passed +- **Window Functions (Pagination with Partition)**: 🟢 Passed +- **Transactions**: 🟢 Passed + +## Conclusion + +DuckDB support is fully verified and stable. diff --git a/teaql-duckdb/pom.xml b/teaql-duckdb/pom.xml new file mode 100644 index 00000000..0f0cfea8 --- /dev/null +++ b/teaql-duckdb/pom.xml @@ -0,0 +1,23 @@ + + + 4.0.0 + + io.teaql + teaql-java-parent + 1.525-RELEASE + + teaql-duckdb + teaql-duckdb + + + io.teaql + teaql-data-service-sql + + + io.teaql + teaql-utils + + + diff --git a/teaql-duckdb/pom.xml.versionsBackup b/teaql-duckdb/pom.xml.versionsBackup new file mode 100644 index 00000000..e50e1673 --- /dev/null +++ b/teaql-duckdb/pom.xml.versionsBackup @@ -0,0 +1,23 @@ + + + 4.0.0 + + io.teaql + teaql-java-parent + 1.522-RELEASE + + teaql-duckdb + teaql-duckdb + + + io.teaql + teaql-data-service-sql + + + io.teaql + teaql-utils + + + diff --git a/teaql-duckdb/src/main/java/io/teaql/core/duck/DuckDataServiceExecutor.java b/teaql-duckdb/src/main/java/io/teaql/core/duck/DuckDataServiceExecutor.java new file mode 100644 index 00000000..211bc4a8 --- /dev/null +++ b/teaql-duckdb/src/main/java/io/teaql/core/duck/DuckDataServiceExecutor.java @@ -0,0 +1,63 @@ +package io.teaql.core.duck;

The goal is to provide a unified, zero-code way to control log outputs, formatting, and granularity across all supported languages (Java, Rust). + +## 1. Output & Routing (System Level) +Controls where and how logs are written. +* `TEAQL_LOG_ENDPOINT`: Specifies the exact destination for logs (e.g., `stdout`, `off`, or a file path like `/var/log/app.log`). +* `TEAQL_DOMAIN`: Acts as a fallback for the log file name. If `TEAQL_LOG_ENDPOINT` is not set, logs will default to `${TEAQL_DOMAIN}.log`. +* `TEAQL_LOG_FORMAT`: Determines the log output format (`human`, `json`, `debug`). +* `TEAQL_LOG_MAX_SIZE` / `TEAQL_LOG_MAX_FILES`: Configures rolling file strategies (e.g., `50MB`, `7`). + +## 2. Level Control (Module Level) +Controls the verbosity of three core modules. The standard prefix is `TEAQL_{MODULE}_LOG`. +Allowed values: +- `_silent`: No output. +- `_summary`: Skeleton fields (e.g., execution time, status, basic identifier). +- `_full`: Includes business intent and essential payload. +- `_full_with_payload`: Includes full request/response bodies or deep debugging data. + +### Core Modules: +* **`TEAQL_AUDIT_LOG`** + * **Scope**: Entity lifecycle and mutations (Create, Update, Delete). + * **Default**: `_full` (production compliance standard). +* **`TEAQL_SQL_LOG`** + * **Scope**: Underlying database SQL execution. + * **Default**: `_summary` or `_silent` (to prevent flooding production logs). +* **`TEAQL_TOOL_LOG`** + * **Scope**: Tooling and external integrations (HTTP calls, File I/O, etc.). + * **Default**: `_full`. + +## 3.

Initialization & Wiring + +To use TeaQL in your Android application, wire up the repository and register the data services in your custom `UserContext` initialization path. + +### Step 3.1: Open native SQLite Database +Usually, you open the database via a custom `SQLiteOpenHelper`: + +```java +public class MyDbHelper extends SQLiteOpenHelper { + public MyDbHelper(Context context) { + super(context, "my_app.db", null, 1); + } + // ... onCreate, onUpgrade +} +``` + +### Step 3.2: Initialize TeaQL Components +Once you have the database instance, wrap it and configure the TeaQL data service: + +```java +// Open or get database helper +MyDbHelper helper = new MyDbHelper(context); +SQLiteDatabase sqliteDb = helper.getWritableDatabase(); + +// 1. Wrap with TeaQLDatabase +TeaQLDatabase teaqlDb = new AndroidTeaQLDatabase(sqliteDb); + +// 2. Initialize the PortableSQLDataService +PortableSQLDataService dataService = new PortableSQLDataService(teaqlDb); + +// 3. Register entity repositories with the data service +// Note: These descriptors and entity classes are generated by the TeaQL Compiler +EntityDescriptor taskDescriptor = Task.DESCRIPTOR; // example generated descriptor +PortableSQLRepository taskRepo = new PortableSQLRepository(taskDescriptor, teaqlDb); + +dataService.registerRepository(taskRepo); +``` + +### Step 3.3: Set Up UserContext +To make the database operations accessible through the generated API, wire `PortableSQLDataService` as the data store on the user's transaction/execution context: + +```java +UserContext userContext = new UserContext(); +userContext.setDataStore(dataService); +``` + +--- + +## 4. Querying and Mutations + +Now, you can execute standard TeaQL generated request models natively: + +### Example Query +```java +// Execute a query to find all active tasks +List tasks = Q.tasks() + .filterByStatus("ACTIVE") + .purpose("Show user's dashboard") + .executeForList(userContext); +``` + +### Example Mutation +```java +// Mutate (Save/Update/Delete) entities +Task task = new Task(); +task.setName("Integrate TeaQL"); +task.setStatus("ACTIVE"); + +// This updates state, versions, and persists via the PortableSQLDataService +task.save(userContext); +``` + +--- + +## 5. Best Practices for Android + +### Thread Safety & Threading Model +Android's `SQLiteDatabase` handles multi-threaded accesses internally using locks, but executing heavy queries on the main thread will cause application UI freeze/ANR (Application Not Responding). +* Always dispatch TeaQL DB executions (queries/mutations) using a background thread pool, `AsyncTask`, or Kotlin Coroutines (`Dispatchers.IO`). +* Ensure you reuse a single, shared `SQLiteOpenHelper` instance across the entire application to avoid thread conflict and database locking exceptions. + +### Schema Generation and Upgrades +* Use `dataService.ensureSchema(userContext, "Task")` during application startup or within `SQLiteOpenHelper.onCreate()` to automatically compile and create tables for all registered repositories if they do not exist. +* For schema migrations, either leverage `dataService.ensureSchema(userContext, "Task")` (which automatically detects missing tables/columns) or manage migrations using Android's native `onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion)` override. diff --git a/teaql-sql-portable/pom.xml b/teaql-sql-portable/pom.xml new file mode 100644 index 00000000..4a5c1688 --- /dev/null +++ b/teaql-sql-portable/pom.xml @@ -0,0 +1,49 @@ + + + 4.0.0 + + io.teaql + teaql-java-parent + 1.525-RELEASE + + + teaql-sql-portable + teaql-sql-portable + Portable SQL implementation for TeaQL, works on Android and JVM without spring-jdbc + + + + io.teaql + teaql-core + + + io.teaql + teaql-utils + + + io.teaql + teaql-runtime + ${project.version} + + + com.fasterxml.jackson.core + jackson-databind + 2.13.5 + + + + + junit + junit + test + + + org.xerial + sqlite-jdbc + 3.45.1.0 + test + + + diff --git a/teaql-sql-portable/pom.xml.versionsBackup b/teaql-sql-portable/pom.xml.versionsBackup new file mode 100644 index 00000000..1f50b044 --- /dev/null +++ b/teaql-sql-portable/pom.xml.versionsBackup @@ -0,0 +1,49 @@ + + + 4.0.0 + + io.teaql + teaql-java-parent + 1.522-RELEASE + + + teaql-sql-portable + teaql-sql-portable + Portable SQL implementation for TeaQL, works on Android and JVM without spring-jdbc + + + + io.teaql + teaql-core + + + io.teaql + teaql-utils + + + io.teaql + teaql-runtime + ${project.version} + + + com.fasterxml.jackson.core + jackson-databind + 2.13.5 + + + + + junit + junit + test + + + org.xerial + sqlite-jdbc + 3.45.1.0 + test + + + diff --git a/teaql-sql-portable/src/main/java/io/teaql/core/internal/TempRequest.java b/teaql-sql-portable/src/main/java/io/teaql/core/internal/TempRequest.java new file mode 100644 index 00000000..a53acd39 --- /dev/null +++ b/teaql-sql-portable/src/main/java/io/teaql/core/internal/TempRequest.java @@ -0,0 +1,65 @@ +package io.teaql.core.internal;
