ulimit -c unlimited:这条命令告诉系统允许生成无限大小的 Core Dump 文件。 步骤2: 编写 Python 代码 接下来,编写一段示例 Python 代码,模拟程序崩溃的情况。 # example.pyimportctypes# 引入 libc 库libc=ctypes.CDLL('libc.so.6')# 创建一个故意导致崩溃的函数defcrash():# 调用一个不存在的函数,这将引...
# simple_script.pyimportctypes ctypes.string_at(0)# Access NULL pointer to trigger coredump 1. 2. 3. 3. 运行Python脚本,触发coredump 运行修改后的Python脚本,可以通过以下命令触发coredump: python simple_script.py 1. 4. 分析coredump文件,定位问题 当脚本出现coredump后,系统会生成coredump文件,我们可以...
执行 gdb /opt/python-3.9.6/bin/pip3 core-file 根本就打印不出 backtrace 出来,因为 pip3 本身是个 python 文本文件,而不是二进制可执行程序。 好吧,调试 pip3 这个 python 文件: $ python -m pdb /opt/python-3.9.6/bin/pip3 list > /opt/python-3.9.6/bin/pip3(3)<module>() -> import r...
importosdefmy_exploding_func():a =1call_nonexistent_func()try: my_exploding_func()exceptException, e: os.abort() The thing about the core dump generated from this script is that runningpy-btonly gives us the stack trace from the point that we calledos.abort(), which is pretty useless...

from distutils.coreimportsetupsetup(name='foo',version='1.0',py_modules=['foo'],) setup函数的参数表示提供给Distutils的信息,这些参数分为两类:包的元数据(包名、版本号)以及包的信息(本例中是一个Python模块的列表);模块由模块名表示,而不是文件名(对于包和扩展而言也是这样);建议可以提供更多的元数据,...
