Juxtapose

1. Intro

基于 SourceGenerator 的硬编码 .Net进程运行库。

2. Features

  • 可以为类型接口静态类生成代理,无需手动编写RPC相关代码,即可多进程运行;
  • 编译时生成所有代码,运行时无显式的反射调用和动态构造;
  • 支持委托CancellationToken类型的方法参数(其余类型未特殊处理,将会进行序列化,目前回调委托不支持嵌套和CancellationToken);
  • 支持LinuxWindows(其它未测试);
  • 支持调试子进程(Windows&&VisualStudio Only);

注意事项

  • 目前参数不支持定义为父类型,实际传递子类型,序列化时将会按照定义的类型进行序列化和反序列化,会导致具体类型丢失;
  • 目前所有的参数都不应该在方法完成后进行保留,CancellationToken委托等在方法完成后会被释放;

3. Requirement

  • .Net5.0+(其它版本没有尝试过)

4. 使用方法

4.1 引用包

<ItemGroup>
  <PackageReference Include="Juxtapose" Version="1.0.2" />
  
</ItemGroup>

4.2 建立上下文

4.2.1 创建上下文类型,并使用 [Illusion] 特性指定要生成的类型
[Illusion(typeof(Greeter), typeof(IGreeter), "Juxtapose.Test.GreeterAsIGreeterIllusion")]
public partial class GreeterJuxtaposeContext : JuxtaposeContext
{
}

示例代码将为Greeter生成IGreeter接口的代理类型Juxtapose.Test.GreeterAsIGreeterIllusion

Note!!!

  • 必须继承JuxtaposeContext
  • 必须标记partial关键字;

4.2.2 [Illusion] 的多种用法
  • 直接为类型生成代理,如下示例生成 Juxtapose.Test.GreeterIllusion 类型,且不继承接口(静态类型相同用法)
[Illusion(typeof(Greeter))]
  • 为类型生成代理,并继承指定接口,如下示例生成 Juxtapose.Test.GreeterAsIGreeterIllusion 类型且继承IGreeter接口
[Illusion(typeof(Greeter), typeof(IGreeter))]
  • 生成类型,并指定类型名称,如下示例生成 Juxtapose.Test.HelloGreeter 类型
[Illusion(typeof(Greeter), generatedTypeName: "Juxtapose.Test.HelloGreeter")]
  • 生成从IoC容器获取的接口代理类型,如下示例生成 Juxtapose.Test.IGreeterIllusionFromIoCContainer 类型(此时Context类需要实现IIoCContainerProvider接口,并提供有效的IServiceProvider
[Illusion(typeof(IGreeterFromServiceProvider), generatedTypeName: "Juxtapose.Test.IGreeterIllusionFromIoCContainer", fromIoCContainer: true)]

4.3 添加入口点

Main方法开始处添加入口点代码,并使用指定上下文

await JuxtaposeEntryPoint.TryAsEndpointAsync(args, GreeterJuxtaposeContext.SharedInstance);

到此已完成开发,创建类型Juxtapose.Test.GreeterAsIGreeterIllusion的对象,并调用其方法,其实际逻辑将在子进程中运行;

5. 调试子进程(Windows&&VisualStudio Only)

5.1 引用调试包

在Host项目文件中添加包引用

<ItemGroup Condition="'$(Configuration)' == 'Debug'">
  <PackageReference Include="Juxtapose.VsDebugger" Version="1.0.0" />
</ItemGroup>
建议和示例代码一样,添加条件引用,只在Debug环境下引用调试包

5.2 添加入口点

Main方法开始处添加调试入口点代码

JuxtaposeDebuggerAttacher.TryAttachToParent(args);

在代码中打上断点,运行时将会正确命中断点(只在 VisualStudio2022 17.0.5 && Win11 21TH2 中进行了测试,理论上是通用)

6. 工作逻辑

SourceGenerator在编译时生成代理类型,封装通信消息。在创建代理类型对象时,会自动创建子进程,并在子进程中创建目标类型的对象,使用命名管道进行进程间通信,使用System.Text.Json进行消息的序列化与反序列化。
