通过AssemblyLoadContext 卸载清空Roslyn动态编译缓存数据
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
凯亚 (Kayak) 是什么?
凯亚(Kayak)是基于.NET8.0软件环境下的surging微服务引擎进行开发的, 平台包含了微服务和物联网平台。支持异步和响应式编程开发，功能包含了物模型,设备,产品,网络组件的统一管理和微服务平台下的注册中心，服务路由，模块，中间服务等管理。还有多协议适配(TCP,MQTT,UDP,CoAP,HTTP,Grpc,websocket,rtmp,httpflv,webservice,等),通过灵活多样的配置适配能够接入不同厂家不同协议等设备。并且通过设备告警,消息通知,数据可视化等功能。能够让你能快速建立起微服务物联网平台系统。

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

7ffe3723cf88 82,411 6,445,384 System.String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
1.Roslyn.Utilities.StringTable+Entry[]
2.Microsoft.CodeAnalysis.Syntax.InternalSyntax.SyntaxNodeCache+Entry[]
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
2.创建CustomAssemblyLoadContext，代码如下：
public class CustomAssemblyLoadContext : AssemblyLoadContext
{
private string _assemblyDirectory;
public CustomAssemblyLoadContext(string assemblyDirectory)
: base(isCollectible: true)
{
_assemblyDirectory = assemblyDirectory;
}
protected override Assembly Load(AssemblyName assemblyName)
{
var assemblyPath = Path.Combine(_assemblyDirectory, $"{assemblyName.Name}.dll");
if (File.Exists(assemblyPath))
{
return LoadFromAssemblyPath(assemblyPath);
}
return null;
}
}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：
public void RegisterProxType(string[] namespaces,params Type[] types)
{
if (!ServiceLocator.IsRegistered<IServiceProxyGenerater>())
{
var loading = LoadAssembly(Path.Combine(AppContext.BaseDirectory, "Surging.Core.ProxyGenerator.Extensions.dll"));
InvokeFunc(loading.assembly, types, namespaces);
loading.loadContext.Unload();
}
else
{
var proxyGenerater = _serviceProvider.GetService<IServiceProxyGenerater>();
var serviceTypes = proxyGenerater.GenerateProxys(types, namespaces).ToArray();
_serviceTypes = _serviceTypes.Except(serviceTypes).Concat(serviceTypes).ToArray();
proxyGenerater.Dispose();
GC.WaitForPendingFinalizers();
GC.Collect();
}
}
publicvoid InvokeFunc(Assembly assembly, Type[] types,string[] namespaces)
{
var type = assembly.GetType("Surging.Core.ProxyGenerator.Extensions.ServiceProxyGenerater");
DefaultServiceIdGenerator serviceIdGenerator = _serviceProvider.GetService<IServiceIdGenerator>() as DefaultServiceIdGenerator;
var logger = _serviceProvider.GetService<ILogger<ServiceProxyFactory>>();
var obj = assembly.CreateInstance("Surging.Core.ProxyGenerator.Extensions.ServiceProxyGenerater");
var methodGenerateProxys = type.GetMethod("GenerateProxys");
var serviceTypes = methodGenerateProxys.Invoke(obj, new object[] { types, namespaces });
_serviceTypes = _serviceTypes.Except(serviceTypes as Type[]).Concat(serviceTypesas Type[]).ToArray();
var methodDispose = type.GetMethod("Dispose");
methodDispose.Invoke(obj, null);
}4.把AddRelateService改成AddRelateService2就能卸载清空缓存数据了
var host = new ServiceHostBuilder()
.RegisterServices(builder =>
{
builder.AddMicroService(option =>
{
option.AddServiceRuntime()
// .AddRelateService() // no unload Proxy Generator
.AddRelateService2()//load and unload Proxy Generator
.AddConfigurationWatch()
//option.UseZooKeeperManager(new ConfigInfo("127.0.0.1:2181"));
.AddServiceEngine(typeof(SurgingServiceEngine));
builder.Register(p => new CPlatformContainer(ServiceLocator.Current));
});
})
.ConfigureLogging(logger =>
{
logger.AddConfiguration(
Core.CPlatform.AppConfig.GetSection("Logging"));
})
.UseServer(options => { })
.UseProxy()
.UseConsoleLifetime()
.Configure(build =>
build.AddCacheFile("${cachepath}|cacheSettings.json", basePath: AppContext.BaseDirectory, optional: false, reloadOnChange: true))
.Configure(build =>
build.AddCPlatformFile("${surgingpath}|surgingSettings.json", optional: false, reloadOnChange: true))
.Configure(build => build.UseApollo(apollo => apollo.AddNamespaceSurgingApollo("surgingSettings")))
.UseStartup<Startup>()
.Build();
using (host.Run())
{
Console.WriteLine($"服务端启动成功，{DateTime.Now}。");
}再然后通过dump 分析一下结果：

Total 255,601 objects, 60,449,965 bytes通过以上分析发现缓存数据没有了，最近有很多国外友人进行测试访问，udp,tcp,mqtt,sip,rtmp都在进行测试，发现有些内存碎片化的free 得不到立即回收，到时候花时间看看。
