通过AssemblyLoadContext 卸载清空Roslyn动态编译缓存数据

嗅叽 昨天 11:09
一、前言

       前段时间更新发布了dotnetty，内存泄漏问题得到了修复，而后分析dump发现，还有Roslyn动态编译缓存数据没有得到回收，通过统计有5mb左右，这个占比可是整个项目的1/10，
然后通过分析是静态缓存数据，没有扩展方法可以清理，所以求助了Roslyn 社区，他们也非常热心，有一个中国的朋友点醒我用AssemblyLoadContext 卸载就能把缓存数据清空，谈到AssemblyLoadContext 卸载，用这个功能碰到问题，还是我提出的呢！以下是问题链接：
https://github.com/dotnet/runtime/issues/12143
https://github.com/dotnet/roslyn/issues/79624
 那么此篇文章的目的就是如何通过AssemblyLoadContext卸载清空Roslyn动态编译缓存数据

注：测试服务器带宽只有8MB, httpflv  缓冲做的没有rtmp好，然后httpflv卡就多刷新几次

二、dump分析

通过导出dump文件，先通过windbg进行分析，通过!dumpheap -stat分析结果如下

通过以上呈现的分析结果，发现有类型Microsoft.CodeAnalysis.Syntax，Roslyn停留在内存得不到回收，而这些就是Roslyn动态编译的缓存数据，
然后用VS可以看到具体内容

三、代码修改

得到社区提醒帮助，然后着手修改，
1.以surging 为例，首先先独立新的模块Surging.Core.ProxyGenerator.Extensions，把CompilationUtilitys.cs 和ServiceProxyGenerater.cs文件添加进来，以便更好的卸载，效果如下
3.png

2.创建CustomAssemblyLoadContext，代码如下：
  1.     public class CustomAssemblyLoadContext : AssemblyLoadContext
  2.     {
  3.         private string _assemblyDirectory;
  5.         public CustomAssemblyLoadContext(string assemblyDirectory)
  6.             : base(isCollectible: true)
  7.         {
  8.             _assemblyDirectory = assemblyDirectory;
  9.         }
  11.         protected override Assembly Load(AssemblyName assemblyName)
  12.         {
  13.             var assemblyPath = Path.Combine(_assemblyDirectory, $"{assemblyName.Name}.dll");
  14.             if (File.Exists(assemblyPath))
  15.             {
  16.                 return LoadFromAssemblyPath(assemblyPath);
  17.             }
  18.             return null;
  19.         }
  20.     }
复制代码
3.装卸载Surging.Core.ProxyGenerator.Extensions，通过ServiceLocator.IsRegistered判断就可以选择性使用，代码如下：
  1.   public void RegisterProxType(string[] namespaces,params Type[] types)
  2.   {
  3.       if (!ServiceLocator.IsRegistered<IServiceProxyGenerater>())
  4.       {
  5.           var loading = LoadAssembly(Path.Combine(AppContext.BaseDirectory, "Surging.Core.ProxyGenerator.Extensions.dll"));
  6.           InvokeFunc(loading.assembly, types, namespaces);
  7.           loading.loadContext.Unload();
  8.       }
  9.       else
  10.       {
  11.           var proxyGenerater = _serviceProvider.GetService<IServiceProxyGenerater>();
  12.           var serviceTypes = proxyGenerater.GenerateProxys(types, namespaces).ToArray();
  13.           _serviceTypes = _serviceTypes.Except(serviceTypes).Concat(serviceTypes).ToArray();
  14.           proxyGenerater.Dispose();
  15.           GC.WaitForPendingFinalizers();
  16.           GC.Collect();
  17.       }
  19.   }
  21.   public  void InvokeFunc(Assembly assembly, Type[] types,string[] namespaces)
  22.   {
  23.       var type = assembly.GetType("Surging.Core.ProxyGenerator.Extensions.ServiceProxyGenerater");
  24.       DefaultServiceIdGenerator serviceIdGenerator = _serviceProvider.GetService<IServiceIdGenerator>() as DefaultServiceIdGenerator;
  25.       var logger = _serviceProvider.GetService<ILogger<ServiceProxyFactory>>();  
  26.      
  27.       var obj = assembly.CreateInstance("Surging.Core.ProxyGenerator.Extensions.ServiceProxyGenerater");
  29.       var methodGenerateProxys = type.GetMethod("GenerateProxys");
  30.       var serviceTypes = methodGenerateProxys.Invoke(obj, new object[] { types, namespaces });
  32.       _serviceTypes = _serviceTypes.Except(serviceTypes as Type[]).Concat(serviceTypes  as Type[]).ToArray();
  34.       var methodDispose = type.GetMethod("Dispose");
  35.       methodDispose.Invoke(obj, null);
  36.       
  38.   }
复制代码
4.把AddRelateService改成AddRelateService2就能卸载清空缓存数据了
  1. var host = new ServiceHostBuilder()
  2.     .RegisterServices(builder =>
  3.     {
  4.         builder.AddMicroService(option =>
  5.         {
  6.             option.AddServiceRuntime()
  7.            // .AddRelateService() // no unload Proxy Generator
  8.             .AddRelateService2()//load and unload Proxy Generator
  9.             .AddConfigurationWatch()
  10.             //option.UseZooKeeperManager(new ConfigInfo("127.0.0.1:2181"));
  11.             .AddServiceEngine(typeof(SurgingServiceEngine));
  12.             builder.Register(p => new CPlatformContainer(ServiceLocator.Current));
  13.         });
  14.     })
  15.     .ConfigureLogging(logger =>
  16.     {
  17.         logger.AddConfiguration(
  18.             Core.CPlatform.AppConfig.GetSection("Logging"));
  19.     })
  20.     .UseServer(options => { })
  21.     .UseProxy()
  22.     .UseConsoleLifetime()
  23.     .Configure(build =>
  24.     build.AddCacheFile("${cachepath}|cacheSettings.json", basePath: AppContext.BaseDirectory, optional: false, reloadOnChange: true))
  25.       .Configure(build =>
  26.     build.AddCPlatformFile("${surgingpath}|surgingSettings.json", optional: false, reloadOnChange: true))
  27.          .Configure(build => build.UseApollo(apollo => apollo.AddNamespaceSurgingApollo("surgingSettings")))
  28.     .UseStartup<Startup>()
  29.     .Build();
  31. using (host.Run())
  32. {
  33.     Console.WriteLine($"服务端启动成功，{DateTime.Now}。");
  34. }
复制代码
