From 75f7a726c1581d4fbfbaf1e587808cabb8ae08a2 Mon Sep 17 00:00:00 2001 From: "deepsource-dev-autofix[bot]" <61578317+deepsource-dev-autofix[bot]@users.noreply.github.com> Date: Fri, 13 Jun 2025 13:24:26 +0000 Subject: [PATCH] refactor: replace tempnam with tmpfile context manager This PR addresses a security concern by replacing the deprecated and insecure os.tempnam calls with a context-managed os.tmpfile usage. It also standardizes the indentation of subprocess.Popen and os.system calls for improved readability. - Use of `tempnam` detected: os.tempnam can produce predictable temporary file names, leading to potential security vulnerabilities and resource leaks. We replaced these calls with `with os.tmpfile() as tmp_file:` (and `as tmpf:`) to ensure files are created securely and cleaned up automatically. Additionally, we corrected the indentation of subsequent subprocess.Popen and os.system operations to maintain consistent code style. > This Autofix was generated by AI.
