直接通过命令行来启用,运行时添加-X faulthandler参数即可: python3 -X faulthandler my_script.py 2.2 使用效果演示 代码示例(建议在linux上运行该代码): importtracebackdeftest_segmentation_fault():#对于segmentation fault并不能catch到异常,即此处try没效果try: ctypes.string_at(0)exceptException as e:print...

However, it's still not SegmentationFault. Author r00t-Taurus commented Sep 22, 2023 What can I do to catch this bug? What information can I provide? I forgot to mention that it runs under venv and docker. Owner yifeikong commented Sep 25, 2023 venv and docker should not be related...

最近在代码评审的过程,发现挺多错误使用eval导致代码注入的问题,比较典型的就是把eval当解析dict使用,有的就是简单的使用eval,有的就是错误的封装了eval,供全产品使用,这引出的问题更严重,这些都是血淋淋的教训,大家使用的时候多加注意。 下面列举一个实际产品中的例子,详情见bug83055: ...

Running numpy tests, causes a segmentation fault. Steps to reproduce: create a venv pip install numpy pytest hypothesis Respective package versions are: ~/pyston38$ pip freeze asv==0.4.2 attrs==21.2.0 hypothesis==6.14.1 iniconfig==1.1.1 ...
-c or --catch will cause the control-C interrupt to be handled more gracefully. Instead of interrupting the test process immediately, the currently running test will be completed and then the partial results up to the interruption will be reported. If you're impatient, a second press of cont...
使用gdb调试程序时,可以用tcatch命令设置catchpoint只触发一次。例如: int main() { pid_t pid; int i = 0; for (i = 0;i < 4; ++i) { if ((pid = fork()) < 0) //fork error exit(1); else if (pid == 0) //child exit(0); } printf("Hello World\n");//parent return 0; ...
