You need to add a flag to run run -e so that you can avoid getting a traceback to the unittest module in the IPython shell.
您需要添加一个标记以运行 run-e，这样一来，您就可以在IPython Shell 中避免回溯到单元测试模块。
If the CONFIG_FRAME_POINTER option was set during kernel compilation, the frame pointer register is used to maintain stacks and, hence, the stack traceback can be performed correctly.
如果内核编译期间设置了CONFIG_FRAME _ POINTER选项，那么就用帧指针寄存器来维护堆栈，从而就可以正确地执行堆栈回溯。
If no address is provided, it takes the current registers to traceback the stack.
如果没有提供地址，那么它采用当前寄存器来回溯堆栈。
Errors, on the other hand, are unexpected problems — since we do not know in advance what can go wrong, we need to examine the traceback in the actual test run to diagnose such problems.
另一方面，错误是意外的问题——因为我们事先不知道哪里会出错，我们需要分析实际测试运行中的回溯来诊断这种问题。
Otherwise, it assumes the provided address as a valid stack frame start address and attempts to traceback.
否则，它假定所提供的地址是有效的堆栈帧起始地址并设法进行回溯。
For example, on an i386 machine, the % ebp register can be used to traceback the entire stack.
例如，在i386机器上，%ebp寄存器可以用来回溯整个堆栈。
Slightly more sophisticated is to catch wider spans of code, but to use a language's introspection capabilities to report traceback information
稍微复杂一点的解决方案是让捕获代码的范围更宽一些，但要使用语言的内省能力来报告追溯信息
Listing 13 shows the traceback code specific to needleman-wunsch.
清单13显示了特定于Needleman - wunsch算法的回溯代码。
Probabilistic Packet Marking for IP Traceback was proposed to defend against distributed denial-of-service attacks.
数据包抽样标记技术是为了应对分布式拒绝服务攻击而提出的一种IP追踪技术。
As the attackers usually use IP spoofing to conceal their real location, people started to study the IP Traceback.
攻击者使用IP欺骗来隐藏自己的真实地址，因此人们开始研究IP源回溯技术。
The traceback element may write, decode, and trace stored trace bits to decode the encoded signal.
回溯跟踪部件可以对所存储的跟踪比特进行写入、解码和跟踪，以便对编码信号进行解码。
IP traceback is an important way to defend against distributed denial of service attack.
IP追踪是防御分布式拒绝服务攻击的重要方法。
IP traceback is an important way to defend against distributed denial of service attack.
