Anything else adds overhead to the dedicated finalizer thread which can result in blocking. Is your cleanup code thread safe? For your thread safe types, make sure that your cleanup code is also thread safe. You need to do this to synchronize your cleanup code in the case where multiple ...
“Available属性用于确定在网络缓冲区中排队等待读取的数据的量。如果数据可用,可调用Read获取数据。如果无数据可用,则Available属性返回 0。 如果远程主机处于关机状态或关闭了连接,则Available属性将引发SocketException。如果远程主机处于关机状态或关闭了连接,则Available属性将引发SocketException”。 也就是说,错误的原因在...
Deadlock. The top-level method is blocking the context thread, waiting for GetJsonAsync to complete, and GetJsonAsync is waiting for the context to be free so it can complete. 死锁。顶级方法是阻止上下文线程,等待 GetJsonAsync 完成,而 GetJsonAsync 正在等待上下文空闲,以便它可以完成。 For the ...
There are other ways to get into a midlife crisis, such as holding onto objects before making a blocking call like querying a database, blocking on another thread, or calling a Web service. During the call, one or more collections can occur and result in cheap ...
While Thread A is executing, it tries to acquire another resource held by Thread B, so it waits for this resource to be available. While Thread B holds this resource, it generates an error. The SetErrorInfoWithExceptionLogging function is then called on Thread B, blocking the attempt to ...
If you do not need to extend your class design, avoid virtual members because they are more expensive to call due to a virtual table lookup and they defeat certain run-time performance optimizations. For example, virtual members cannot be inlined by the compiler. Additionally, when you allow ...
BlockingQueue:阻塞队列,存储等待执行的任务。参数有ArrayBlockingQueue、LinkedBlockingQueue、SynchronousQueue可选。 ThreadFactory:线程工厂,用来创建线程 RejectedExecutionHandler:队列已满,而且任务量大于最大线程的异常处理策略。 怎么使用线程池呢?ExecutorService.submit(new Runable(){重写run方法})从线程池中获取线程对象...
The Completer API is amuchmore powerful way to integrate with YCM and it provides a wider set of features. For instance, you can make your Completer query your semantic back-end in an asynchronous fashion, thus not blocking Vim's GUI thread while your completion system is processing stuff. ...

The EndInvoke function can also be used for blocking the current thread until the corresponding thread finishes its execution. A call to EndInvoke will block the current thread. The C# code using EndInvoke to block the thread follows: public void MyDelegate(int i, string str); public static ...
