线程池状态： 线程池的5种状态：RUNNING、SHUTDOWN、STOP、TIDYING、TERMINATED。 见 ThreadPoolExecutor 源码 // runState is stored in the high-order bits private static final int RUNNING = -1 <<COUNT_BITS; private static final int SHUTDOWN = 0 <<COUNT_BITS; private static final int STOP = 1 <<COUNT_BITS; private static final int TIDYING = 2 <<COUNT_BITS; private static final int TERMINATED = 3 <<COUNT_BITS; 1. RUNNING：线程池一旦被创建，就处于 RUNNING 状态，任务数为 0，能够接收新任务，对已排队的任务进行处理。 2. SHUTDOWN：不接收新任务，但能处理已排队的任务。调用线程池的 shutdown() 方法，线程池由 RUNNING 转变为 SHUTDOWN 状态。 3. STOP：不接收新任务，不处理已排队的任务，并且会中断正在处理的任务。调用线程池的 shutdownNow() 方法，线程池由

Java 并发工具包中 java.util.concurrent.ExecutorService 接口定义了线程池任务提交、获取线程池状态、线程池停止的方法等。 JDK 1.8 中，线程池的停止一般使用 shutdown()、shutdownNow()、shutdown() + awaitTermination(long timeout, TimeUnit unit) 方法。 1、shutdown() 方法源码中解释 * Initiates an orderly shutdown in which previously submitted * tasks are executed, but no new tasks will be accepted. * Invocation has no additional effect if already shut down. 有序关闭，已提交任务继续执行 不接受新任务 2、shutdownNow() 方法源码中解释 * Attempts to stop all actively executing tasks, halts the * processing of waiting tasks, and returns a list of the tasks * that were awaiting execution.

For some reason, when I type "rails s", sometimes I can't shut the server down using CTRL-C. It's using Web brick, the default. Sometimes it works for hours. Other times it doesn't work at all and I must constantly kill the process if I want to shut down the server. Is this a known problem? How can I fix it? If you need to know more info, please just ask and I'll tell you what I can. Because I don't know what is causing it, I am at a loss as to what info to provide you with. EDIT: I am adding a git repository: gem 'rails-dev-boost', :git => 'git://github.com/thedarkone/rails-dev-boost.git',

Below is the source code of the class. I wanted to verify how does shutdownNow() works for not submitted task. Problem I am getting in below code is shutdownNow() return List<FutureTask> and not List<Runnable> which I have submitted List<Runnable> containing submitted instance of PrimeProducer . In Below program I wanted to get the tasks which where not executed and their state so that I can reschedule them later. name() represents just state that I want to store. So I am not able to convert to submitted Task. class PrimeProducer implements Runnable { private final SynchronousQueue<BigInteger>

一、概述 1. new Thread的弊端 （1）每次new Thread新建对象性能差。 （2）线程缺乏统一管理，可能无限制新建线程，相互之间竞争，及可能占用过多系统资源导致死机或oom（内存溢出）。 （3）缺乏更多功能，如定时执行、定期执行、线程中断。 2. 线程池 线程池是指管理同一组同构工作线程的资源池，线程池是与工作队列(Work Queue)密切相关的，其中在工作队列中保存了所有等待执行的任务。工作线程(Worker Thread)的任务很简单：从工作队列中获取一个任务，执行任务，然后返回线程池并等待下一个任务。 3. 线程池的组成 一个线程池包括以下四个基本组成部分： （1）线程池管理器（ThreadPool）：用于创建并管理线程池，包括 创建线程池，销毁线程池，添加新任务； （2）工作线程（PoolWorker）：线程池中线程，在没有任务时处于等待状态，可以循环的执行任务； （3）任务接口（Task）：每个任务必须实现的接口，以供工作线程调度任务的执行，它主要规定了任务的入口，任务执行完后的收尾工作，任务的执行状态等； （4）任务队列（taskQueue）：用于存放没有处理的任务。提供一种缓冲机制。 4. 什么时候适合使用线程池 在多线程应用中，如果大量的资源都耗费在创建和销毁线程上，那么可以使用线程池。 5. 合理利用线程池带来的好处 （1）降低资源消耗

I know that shutdown -a will abort a Windows shutdown, but I need to know if there is anything any where I can check for to see if a shutdown is in progress. Ideally, I'd like a small program like this: import os while True: shuttingDown = <shutdown variable to check> if shuttingDown: os.system("shutdown.exe -a") For preventing a Windows shutdown when it is happening, you can react to the WM_QUERYENDSESSION message (don't know if you can do that easily with Python's win32 API but it's simple in C). This might not prevent applications from closing because Windows sends WM_ENDSESSION to those
