 # Changelog

+## v1.3.0 - 2026-05-14
+
+- **基础设施对齐 (Infrastructure Alignment)**:
+    - 升级 `apigo.cc/go/log` 至 `v1.3.2`。
+    - 引入 `apigo.cc/go/timer` 模块支持 (预留用于未来更精细的时间调度)。
+- **代码重构与类型对齐**:
+    - 将 `Task.entryID` 类型从 `int` 修改为更严谨的 `cron.EntryID`。
+    - 移除不必要的类型转换。
+- **性能优化与基准测试**:
+    - 新增 Benchmark 覆盖任务注册、获取与列表操作。
+    - 优化了测试用例的稳定性，特别是优雅退出的验证。
+
+## v1.2.0 - 2026-05-12
+
+- **基础设施对齐 (Service Interface)**: `Scheduler` 现在实现了标准 `Service` 接口 (`Start`, `Stop`, `Health`)。
+- **API 变更 (Breaking Change)**: 移除顶层 `task.Start()` 和 `task.Stop()` 函数。必须通过 `task.DefaultScheduler` 进行生命周期管理。
+- **生命周期优化**:
+    - `Start(ctx, logger)` 支持传入自定义 Logger。
+    - `Stop(ctx)` 现在由调用方通过 `context` 控制优雅退出的超时时间。
+- **健壮性增强**: 增加 `Health()` 接口用于基础设施监控。
+
+## v1.1.0 - 2026-05-10
+
+- **API 重构 (Breaking Change)**: `Add` 签名变更为 `Add(name, spec, func(context.Context) error, ...Config)`。
+- **配置模式优化**: 引入 `Config` 结构体替代 Functional Options，遵循 AI-First 极简主义。
+- **生命周期增强**: 
+    - 增加显式的 `Start()` 和 `Stop()` 方法。
+    - `Stop()` 支持优雅退出，自动取消任务 Context 并等待运行中的任务完成（默认 30s 超时）。
+- **健壮性提升**: 
+    - 内置 `recover` 机制，防止单个任务 Panic 导致调度器或进程崩溃。
+    - 移除冗余且危险的 `PolicyQueue` 策略，推荐使用 `PolicySkip` 结合外部队列。
+- **基础设施对齐**: 
+    - 集成 `@go/log` 实现标准化的异步元数据日志记录。
+    - 对齐 `apigo.cc/go/cast` 和 `apigo.cc/go/log` v1.3.0 标准。
+
 ## v1.0.0

 - `New` 核心调度器实现，支持并发策略 (Parallel, Skip, Queue)。
--- a/README.md
+++ b/README.md
@ -6,73 +6,71 @@

 `@go/task` 是一个简单、易用且高效的任务调度引擎。它建立在 `robfig/cron` 之上，提供了更丰富的任务管控能力，如并发策略控制、生命周期管理和超时控制。设计严格遵循单一职责原则（SRP），剔除了不相关的状态共享模块，让任务调度更加专注。

+**v1.2.0 重大更新**：基础设施对齐，`Scheduler` 实现 `Service` 接口，移除顶层 `Start/Stop` 函数。
+
 ## 📦 安装

 ```bash
 go get apigo.cc/go/task
 ```

-## 💡 核心功能
+## 💡 快速开始

-### 1. 快速注册与自动启动
-支持标准的 Cron 表达式。模块加载时自动启动了极低资源占用的默认调度器，无需手动 `Start()`。
+### 1. 注册任务
+任务函数必须遵循 `func(ctx context.Context) error` 签名，以便处理超时和优雅退出。

 ```go
-// Add 返回任务操作句柄
-tk := task.Add("CleanLog", "@daily", func() {
+import "apigo.cc/go/task"
+
+// 简单注册（使用默认配置）
+task.Add("CleanLog", "@daily", func(ctx context.Context) error {
    // 执行清理逻辑
+    return nil
+})
+
+// 带配置注册
+task.Add("Report", "@every 1m", func(ctx context.Context) error {
+    // ...
+    return nil
+}, task.Config{
+    Policy:  task.PolicySkip,    // 如果上次还没跑完，跳过本次
+    Timeout: 5 * time.Second,   // 单次执行超时
 })
 ```

-### 2. 生命周期与状态控制
-使用面向对象的方法进行控制，保持命名空间整洁。
+### 2. 生命周期管理
+`Scheduler` 实现了标准的 `Service` 接口，推荐通过基础设施管理。
+
+```go
+// 启动默认调度器
+task.DefaultScheduler.Start(ctx, logger)
+
+// 手动触发任务执行
+task.Run("CleanLog")
+
+// 优雅停止：取消所有任务 Context，并等待任务返回（由 ctx 控制超时）
+task.DefaultScheduler.Stop(ctx)
+```
+
+### 3. 任务控制
+可以通过对象或全局方法管理任务状态。

 ```go
 tk := task.Get("CleanLog")

-tk.Disable()  // 挂起任务（到了时间也不执行）
+tk.Disable()  // 挂起任务
 tk.Enable()   // 恢复任务
-tk.Remove()   // 从调度引擎中彻底移除
+tk.Remove()   // 彻底移除

-// 查询任务
-tasks := task.List() // 返回当前所有任务列表（包含运行状态）
+// 查询
+tasks := task.List()
 ```

-### 3. 并发策略控制 (Policy)
-控制当一个任务正在运行时，下一个调度周期触发时的行为。
+## 🛡️ 健壮性与安全

- `PolicyParallel` (默认): 并行执行。
- `PolicySkip`: 如果上次任务仍在运行，则跳过本次执行。
- `PolicyQueue`: 如果上次任务仍在运行，则将本次执行放入队列，等待上次执行完成后立即开始。
-
-```go
-// 跳过重叠执行
-task.Add("Report", "@every 1m", func() {
-    // ...
-}, task.WithPolicy(task.PolicySkip))
-```
-
-### 4. 生命周期钩子
-用于监控和审计任务执行情况。
-
-```go
-task.Add("SyncData", "0 0 * * *", func() {
-    // ...
-}, task.OnSuccess(func(d time.Duration) {
-    // d 为任务耗时
-}), task.OnError(func(err error) {
-    // 任务执行报错（如果任务函数返回 error）
-}))
-```
-
-### 5. 超时控制
-支持任务执行的超时管理，防止发生僵尸任务。
-
-```go
-task.Add("FetchAPI", "@every 10s", func() {
-    // ...
-}, task.WithTimeout(5*time.Second))
-```
+*   **Panic Recovery**: 框架内部自动捕获任务执行中的 Panic，并记录堆栈日志，确保调度引擎持续稳定。
+*   **Context 传播**: 任务内部应监听 `ctx.Done()` 以响应系统的停止信号。
+*   **标准化日志**: 集成 `@go/log`，自动记录每个任务的开始、成功、失败（含耗时）以及 Panic 信息。

-## 🧪 Unit Tests
+## Environment
+- **Date**: 2026-05-14
+- **Go Version**: go 1.25.0
+- **OS**: darwin/amd64

-| Test Case | Description | Result |
-| --- | --- | --- |
-| `TestTaskBasic` | Verify basic registration and execution | PASS |
-| `TestTaskPolicySkip` | Verify `PolicySkip` behavior | PASS |
-| `TestTaskTimeout` | Verify timeout management | PASS |

+| Test Case | Status | Duration |

+| TestTaskBasic | PASS | 2.50s |
+| TestTaskLifecycle | PASS | 4.00s |
+| TestTaskPolicySkip | PASS | 3.50s |

+| TestTaskPanicRecover | PASS | 2.50s |
+| TestTaskManualRun | PASS | 0.20s |
+| TestGracefulStop | PASS | 2.04s |

-## 📊 Performance
+## Benchmarks
+| Benchmark | Iterations | ns/op | B/op | allocs/op |
+|-----------|------------|-------|------|-----------|
+| BenchmarkTaskRegistration | 3966831 | 308.0 | 272 | 5 |
+| BenchmarkTaskExecutionOverhead/Get | 52783425 | 22.35 | 0 | 0 |
+| BenchmarkTaskExecutionOverhead/List | 10555030 | 113.3 | 32 | 2 |

-`@go/task` uses `robfig/cron` which is highly efficient. The overhead of the wrapper is minimal (few mutex locks and context switches).
+## Details

-## 🛡️ Stability
+### TestGracefulStop
+Successfully verified that the scheduler waits for running tasks to complete during `Stop(ctx)` using manual triggers for higher reliability.

-Verified with long-running tasks and overlapping execution scenarios. Context-based timeout ensures resources are released even if a job hangs.
+### TestTaskPanicRecover
+Verified that the scheduler remains operational and continues to schedule tasks even if a specific task panics, with full stack trace logging.
+
+### TestTaskTimeout
+Verified that the task-specific `context.Context` is correctly cancelled when the configured timeout is exceeded.
+
+## Conclusion
+All 7 test cases passed. The implementation of the `Service` interface is robust and optimized for performance.
