ebook在这防止过载上做的很好,在C++实现的thrift server上,有一个或者多个threads只负责accept TCP connections. 你可以指定最多的connections for
manner that guarantees safe execution by multiple threads at the same time 这段定义看起来还是有点抽象,我们可以将多线程不安全解释为:
Create network dispatchers (and corresponding threads) up to the pool size. //创造网络请求队列 for (int i = 0;

指定了断点设置在的源程序的行号。threadno指定了线程的ID,注意,这个ID是GDB分配的,可以通过“info threads”命令来查看正在运行程序中的线程信息。如果不指定thread 则表示断点设在所有线程上面。还可以为某线程指定断点条件。如:
