在某一个时刻 , 一种signal 在一个进程中只能有一个实例( 因为进程没有用队列缓存其收到的signal) . 因为有31 种regualar signal , 所以一个进程某一个时刻可以有31 个各类signal 的实例. 此外因为linux 进程对real time signal 采用不同的处理方式, 它会保存接收到的real ...
在某一个时刻,一种signal在一个进程中仅仅能有一个实例(由于进程没实用队列缓存其收到的signal).由于有31种regualar signal,所以一个进程某一个时刻能够有31个各类signal的实例.此外由于linux进程对real time signal採用不同的处理方式,它会保存接收到的real time signal的实例,所以能够同一时候有非常多同种signal的...
它对应的整数值为17,用来表示子进程结束时给父进程发送的消息 (即当子进程结束时应该向父进程发送标识符为17的signal/消息/信号).宏SIGSEGV, 它对应的整数值为11,当进程引用一个无效的物理地址时(内核)会向进程发送标识符为11的signal/消息/信号 (参考linux内存管理的页错误异常...

信号处理可以分成两个阶段:信号产生并通知到接收方(generation), 接收方进行处理(deliver) ... 简介 Unix为了允许用户态进程之间的通信而引入signal.此外, 内核使用signal给进程通知系统事件. 近30年来, signal只有很小的变化. 以下我们先介绍Linuxkernel如何处理signal,然后讨论允许进程间exchange信号的系统调用. The ...

signal generation:内核更新信号的目的进程的相关数据结构,这样该进程就能知道它接收到了一个信号.认为称为收到信号阶段更恰当.这个generation翻译成目的进程接收也不错. signal delivery():内核强制目的进程处理接收到的信号,这主要是通过改动进程的运行状态或者在目的进程中运行信号处理函数来实现的.认为称为处理收到的...

Now, however, concurrent programming is common practice, and you need to be aware of the pitfalls. This article describes some potential problems due to non-reentrancy of the function in parallel and concurrent programming. Signal generation and handling in particular add extra complexity. Due to ...
This is all very reasonable but it does depends on container processes handlingSIGTERMor not handlingSIGTERMand letting the kernel kill the process. Not having a handler for SIGTERM In general, without an explicit handler forSIGTERM, the kernel will kill the process. However, there is one very ...
