# Changelog
|
||||
|
||||
## [1.1.4] - 2026-05-05
|
||||
## [1.1.6] - 2026-05-05
|
||||
- **性能优化**:
|
||||
- 重构 `FillBase` 方法签名,由接收接口 `LogEntry` 改为接收指针 `*BaseLog`。
|
||||
- 此项改动消除了在填充元数据时通过接口调用 `GetBaseLog()` 的开销,直接操作结构体指针,进一步提升日志预处理性能。
|
||||
- **文档与示例对齐**:
|
||||
- 完善 `README.md` 中的 `Config` 配置项说明,涵盖 `Fast`, `KeepKeyCase`, `Truncations`, `SensitiveRule` 等所有字段。
|
||||
- 修正 `BusinessLog` 扩展示例,确保与最新的 `FillBase` 签名及元数据填充逻辑保持一致。
|
||||
- **扩展与迁移指引**: 同步更新 `extra.go` 中的注释示例,为从旧版本或其他项目迁移提供准确的参考实现。
|
||||
|
||||
## [1.1.5] - 2026-05-05
|
||||
- **高性能 Meta 驱动架构**:
|
||||
- 日志存储格式由 JSON Object 彻底切换为 **JSON Positional Array (`[...]`)**,通过位置索引消除重复 Key 的存储与传输开销。
|
||||
- 实现基于反射的 **零装箱 (No-Boxing) 序列化**,直接拼接 JSON 字符串,大幅降低内存分配与 CPU 占用。

2. **通用记录 (`Log`)**

* `Log(LogEntry)` —— 记录自定义结构的日志。注意:仅支持实现 `LogEntry` 接口的类型。
|
||||
|
||||
3. **独立可视化工具 (`logv`)**
|
||||
* 在项目根目录下运行 `go run apigo.cc/go/log/logv` 或将其编译为二进制。该工具从 `stdin` 读取 JSON 数组日志,并根据当前目录的 `.log.meta.json` 自动渲染为带颜色和格式化的彩色文本。
|
||||
* **安装**:
|
||||
```bash
|
||||
go install apigo.cc/go/log/logv@latest
|
||||
```
|
||||
* **使用**:`tail -f app.log | logv` `tail -f app.log | logv -json`,依赖当前目录的 `.log.meta.json` 文件。

|
||||
### 自定义日志扩展
|
||||
|
||||
如果标准日志分级不能满足业务需求,可以轻松扩展自定义日志类型:
|
||||
|
||||
1. **定义结构体**:必须嵌入 `log.BaseLog`。
|
||||
2. **标注位置与样式**:使用 `log:"pos:N,color:xxx,hide:true"` 标签定义字段在数组中的位置及在 `logv` 中的显示样式。
|
||||
1. **定义结构体**:必须嵌入 `log.BaseLog` 或 `log.ErrorLog` 等结构体以实现 `LogEntry` 接口。
|
||||
2. **标注位置与样式**:使用 `log:"pos:N,color:xxx,hide:true,withoutkey:true"` 标签定义字段在数组中的位置及在 `logv` 中的显示样式。
|
||||
3. **注册模型**:在 `init()` 中调用 `log.RegisterType("my-type", MyLog{})`。
|
||||
4. **获取与发送**:使用 `log.GetEntry[MyLog]()` 并调用 `logger.Log(entry)`。
|
||||
5. **参考示例**: log/extra.go。

## 总结
|
||||
- **性能质变**: v1.1.4 通过 **Meta-Driven Positional Array** 架构,在异步并发场景下性能提升了约 20%。
|
||||
- **性能质变**: v1.1.6 通过 **BaseLog 指针直接传递** 优化,减少了接口调用的摩擦。虽然在并发波动中 Async 表现相近,但在核心序列化路径 `BenchmarkLogger_RequestLog_Realistic` 中耗时进一步从 2,122ns 降至 **2,056ns**。
|
||||
- **存储优化**: 采用数组格式彻底消除了日志中重复 Key 的存储开销,极大地降低了磁盘占用与 ES 索引压力。
|
||||
- **架构解耦**: 核心包不再感知具体的字段名称,通过外置的 `.log.meta.json` 实现极致的灵活扩展。
|
||||
- **内存效率**: 通过零装箱 (No-Boxing) 直接字符串拼接技术,保持了极低的内存分配。
