由Autofac引起的棘手的IIS死锁

时间：2013-03-08 03:30:15

标签： iis deadlock autofac

我是Autofac用户，现在面临一个非常头痛的问题。我被电子邮件Alex和Travis问到了这个问题，得到了他们的答复，在此，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。

我的电子邮件：

  

我们在mvc3项目中使用Autofac 2.6.3.862。

     现在我们来到IIS死锁问题严重，服务器经常   挂起，我们使用Microsoft Debug Diagnostics Tool来做   最初怀疑是分析（导致附上分析报告）   成为LifetimeScope的锁定

     

我已阅读过您的文章，但有些技术细节含糊不清   我。我们的大多数Register（）组件都是SingleInstance，所以当   Resolve（）我没有像使用（var scope）那样使用子生命周期范围   = Container.BeginLifetimeScope（））

     

，不知道这是否是死锁的原因。

Alex回复：

  

这听起来像是一个棘手的问题。什么是DIContainer课程   你有任何组件注册为InstancePerHttpRequest，   还是InstancePerLifetimeScope？似乎还有一些Quartz工作   在后台，他们如何与容器互动？

特拉维斯回复：

  

快速查看堆栈跟踪表明您可能有一些   长时间运行的操作或锁定发生在   Spacebuilder.Environments.Starter，   Spacebuilder.Common.UserSearcher.ctor，   Spacebuilder.UserProfileService.ctor，或   Spacebuilder.Common.ProfileRepository。我看到了什么   有趣的是，在RESOLVE操作期间，无论什么时候   组件被解析，内部REGISTER正在进行中。   没有看到代码，我无法告诉你那里发生了什么，但是   那个帖子 - ＃39 - 这就是我所看到的东西。

     

看起来......正在调用一个控制器动作还有一些   运行在闭包上的lambda（DynamicClass.lambda_method） -   在你的管道中定制的东西。 SearcherFactory.GetSearcher   手动尝试解决smoething。在决议期间   GetSearcher，有些东西要求收集 - 就像一个   IEnumerable服务。构造函数参数？这就是它的所在   变得怪异：在解析IEnumerable时，一个新的生命周期范围   正在创建，似乎有些东西正在注册   它？ LifetimeScope.ResolveComponent调用确实执行锁定   确定的解决方案是线程安全的。你正陷入僵局的事实   意味着两个不同的线程试图解决相同的问题   生命期范围（容器？）同时，在MVC中，是   要避免的事情 - 你可能不会遇到这种情况，例如，   如果你只是从HttpRequest生命周期范围解析，那么   你一次只能在一个线程上拥有它。或者，你可以   为了做到这一点，在应用程序中传递生命周期范围   服务地点，也可能是一面红旗。

     

Concurrency上有一个wiki页面，也可以给你一些   指针：https://code.google.com/p/autofac/wiki/Concurrency

     

如果那不能让你朝着你需要的方向前进，我建议你   发布到讨论论坛，再次，我真的不能   及时提供个人帮助。那将会得到   其他的眼睛，可能会尽快给你帮助。您想要包括：   问题的描述（就像在这封电子邮件中一样）但有更多   关于你期望发生什么的详细信息（例如，你正在访问一个   控制器动作，等等等等等等。堆栈的痕迹   阻止线程。事情被阻止的代码：   您的初始ContainerBuilder注册以显示事物的方式   注册。那些构造函数和事物中的内容是什么   挂了该信息将帮助人们更快地根除   问题。这也是你应该尊重的东西   被锁定的事情

我的补充问题详情：

服务器经常不规则挂起，浏览器会突然停止响应我们使用iisreset命令重启服务器。我不确定是否调用了控制器或者是否触发了一些Quartz任务。

在Application_Start（）中，我们使用ContainerBuilder.Register（）来注册同一根生命周期范围内的许多组件。这些组件可能会相互调用。

大多数人注册为SingleInstance，例如：

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();

只有少数注册为InstancePerHttpRequest，这些组件初始化与每个请求相关。如：

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

我们提供了一个类（DIContainer），包括一些用于组件解析的简单静态方法。在解析组件时调用静态方法，例如在某些Controller，Service，Repository（DAO）或Quartz任务中。

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>()
   {

我们使用Lucene.Net进行全文搜索服务，每个ISearcher对应一种搜索和索引目录。在需要时，可以在SearcherFactory.GetSearcher（）中解析ISearcher。

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

就是这样，但我仍然无法弄清楚根本原因。希望得到你的帮助。

Resolve Method的内部工具是LifetimeScope.GetOrCreateAndShare，此方法使用线程锁。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。
