Autofac造成的棘手的IIS死锁

我是Autofac用户，现在面临很头痛的问题。我被电子邮件Alex和Travis问过这个问题，并得到了他们的回复，在这里，感谢他们的帮助。为了彻底检查这个问题，我接受了Travis的建议，在这里发布了详细信息。Autofac造成的棘手的IIS死锁

我的邮箱：

我们使用Autofac 2.6.3.862在MVC3项目。

现在我们来到了IIS死锁问题是严重的，往往挂，我们已经使用了微软的调试诊断工具对服务器做分析（导致封闭分析报告），初步怀疑是一个锁在LifetimeScope中

我已阅读文章，但对于某些技术细节模糊 me。我们的大部分注册的（）成分是SingleInstance，所以当解决（）我不使用AA孩子一生的范围，想用（VAR范围 = Container.BeginLifetimeScope（））

，不知道这是否是僵局的原因。

亚历克斯回复：

这听起来像是一个棘手的一个。什么是DIContainer类做，你有任何注册为InstancePerHttpRequest，或InstancePerLifetimeScope的组件吗？在背景中似乎也有一些石英作业，他们如何与容器进行交互？

特拉维斯回复：

非常快看看堆栈跟踪表明你可能有一些长时间运行的操作或锁在 Spacebuilder.Environments.Starter， Spacebuilder发生。 Common.UserSearcher.ctor， Spacebuilder.UserProfileService.ctor或 Spacebuilder.Common.ProfileRepository。我所看到的是有趣的是，在RESOLVE操作期间，无论组件是否得到RESOLVED，都会有一个内部REGISTER进行。没有看到代码，我不能告诉你那里发生了什么，但那个线程 - ＃39 - 这是我看的东西。

它看起来像一个控制器操作被调用有一些类型的lambda运行在关闭（DynamicClass.lambda_method） - 自定义管道中。 SearcherFactory.GetSearcher 手动尝试解决smoething。在 GetSearcher的解决方案中，有一些要求收集 - 例如IEnumerable服务。一个构造函数参数？这里就是它会很奇怪：在解析该IEnumerable的，是越来越创建一个新的生命周期范围和东西出现在它被越来越注册？该LifetimeScope.ResolveComponent电话确实做了锁，使确保决议是线程安全的。你得到一个僵局，这意味着两个不同的线程试图化解掉在同一时间同一寿命范围（容器？），其中，在MVC，是的东西，以避免 - 你可能不会碰到这种情况，例如，如果你因为只解决了HttpRequest的寿命范围的你只要上一个线程的时间。另外，您也可以围绕路过寿命范围的应用做服务定位的目的，并且，也可以是一个危险的信号。

有上并发维基页面也可以给你一些指针：https://code.google.com/p/autofac/wiki/Concurrency

如果不能让你在你需要的方向发展，我建议张贴到论坛讨论，因为，再，我真的不能够及时地提供个人帮助。这将得到其他的眼睛它可能会帮助你更快。您需要包括：对问题的描述（如本电子邮件中所述），但有更多关于您期望发生的事情的详细信息（例如，您正在访问控制器操作，并执行等等）。阻塞线程的堆栈跟踪。围绕那里的东西是被阻塞的代码：您最初ContainerBuilder登记显示事情是如何登记报名。那些构造函数和挂起的东西是什么。该信息将帮助人们更快地找出问题。这也是你应该尊重的东西在看的东西被锁

我的质询细节：

服务器常常不规则悬挂，浏览器会突然停止响应UTIL我们使用iisreset命令重新启动服务器。我不确定是否有一个控制器被调用或者某些Quartz任务触发了这个时间。

在Application_Start（）中，我们使用ContainerBuilder.Register（）来注册同一根生命周期中的许多组件。而这些组件可能会互相呼叫。

他们大多注册为SingleInstance，如：

containerBuilder.Register(c => new DefaultCacheService(new MemcachedCache())).As<ICacheService>().SingleInstance(); 
containerBuilder.Register(c => new QuartzTaskScheduler()).As<ITaskScheduler>().SingleInstance(); 
containerBuilder.Register(c => new UserService()).As<IUserService>().SingleInstance(); 
containerBuilder.Register(c => new UserSearcher("~/App_Data/IndexFiles/User")).As<ISearcher>().SingleInstance(); 
containerBuilder.Register(c => new TagSearcher("~/App_Data/IndexFiles/Tag")).As<ISearcher>().SingleInstance();

只有注册为InstancePerHttpRequest，这些组件初始化与相关的每个请求数。如：

containerBuilder.Register(c => new FormsAuthenticationService()).As<IAuthenticationService>().InstancePerHttpRequest();

我们提供了一个类（DIContainer），它包含了一些用于组件解析的简单静态方法。何时解析组件，例如在某些Controller，Service，Repository（DAO）或Quartz任务中调用静态方法。

IContainer container = containerBuilder.Build(); 
DIContainer.RegisterContainer(container); 
DependencyResolver.SetResolver(new AutofacDependencyResolver(container)); 

public class DIContainer 
{ 
    private static IContainer _container; 

    public static void RegisterContainer(IContainer container) 
    { 
     _container = container; 
    } 

    public static TService Resolve<TService>() 
    { 
     return _container.Resolve<TService>(); 
    } 
    ...... 
}

我们使用Lucene.Net的全文搜索服务，每个ISearcher对应一种类型的搜索和索引目录。 ISearcher在需要时在SearcherFactory.GetSearcher（）中解析。

public static ISearcher GetSearcher(string IndexPath) 
{ 
    return DIContainer.Resolve<IEnumerable<ISearcher>>().Where(s => s.IndexPath.Equals(IndexPath, StringComparison.InvariantCultureIgnoreCase)).FirstOrDefault(); 
}

这就是，但我仍然无法弄清楚根本原因。希望你的帮助。

硬盘没有看到所有的代码和堆栈跟踪，但第一红旗说的是*“我们提供一个类（DIContainer）包括组件解决一些简单的静态方法。” * < - 你为什么不只是使用Autofac实现的构造函数注入？它会将依赖关系注入到Controllers，Services，...中，而不会诉诸像这样在容器周围传递“静态”代码。你为什么还要继续解决像这样的ISearcher实例？它们不是SearcherFactory生命周期中的一个固定集合，因此被注入到其构造函数中？ – 2013-03-08 03:47:34

鉴于线保持的锁处于'Spacebuilder.Common.ProfileRepository..ctor（）'，'Spacebuilder.Common.UserProfileService..ctor（）'，'Spacebuilder.Common.UserSearcher..ctor（System.String， System.String，Boolean，Int32）'，'Spacebuilder.Environments.Starter.b__54（Autofac.IComponentContext）'链，我们可能需要看到那个代码（正如我原来的回复中提到的那样）。 – 2013-03-08 15:47:47

解决方法的内心工具是LifetimeScope.GetOrCreateAndShare，这种方法使用一个线程锁。检查ProfileRepository的静态构造函数，也许构造函数的线程锁和autofac的线程锁构成死锁。
