How to detect ASAN Address Sanitizer errors of subprocess in Python

Описание: Download this code from https://codegive.com
AddressSanitizer (ASAN) is a powerful tool for detecting memory-related errors in C and C++ programs. However, integrating ASAN with subprocesses in Python requires some additional steps. In this tutorial, we'll explore how to detect ASAN errors in subprocesses when executing external commands using the subprocess module in Python.
Install AddressSanitizer:
Ensure that AddressSanitizer is installed on your system. Most modern compilers like GCC and Clang include ASAN support. If not installed, you may need to install the corresponding package for your operating system.
Create a C/C++ Program with ASAN:
Write a simple C or C++ program that contains memory errors. For example, let's create a file named example.c:
Compile the program with ASAN:
Create a Python Script:
Now, create a Python script that will execute the compiled program using the subprocess module. Save it as detect_asan_errors.py:
Run the Python Script:
Execute the Python script to run the C/C++ program with ASAN:
If there are ASAN errors in the subprocess, the script will print information about the detected errors.
This tutorial provides a basic example, and you can adapt it to your specific use case. Make sure to adjust the script according to your project's requirements and incorporate error handling as needed. Additionally, consider exploring the ASAN documentation for more advanced configuration options: https://clang.llvm.org/docs/AddressSa...
