From 81b0489a17814425dc3375f114a1de4883085749 Mon Sep 17 00:00:00 2001 From: "qwen.ai[bot]" Date: Sun, 19 Jul 2026 05:19:20 +0000 Subject: [PATCH] Title: Resolve CodeQL alerts and improve file handling safety Key features implemented: - Updated .gitignore to include more comprehensive ignore patterns for temp files, compressed archives, compiled files, and IDE-specific files - Fixed potential illegal raise in ai/retry.py by replacing unreachable raise statement with proper error handling - Addressed potentially uninitialized local variable in services/.../v1/routes.py by ensuring variable assignment before use - Fixed writable file handle closure without error handling in Go files by adding proper defer and error checking - Resolved file not always closed warnings in Python files by implementing proper context managers and exception handling - Corrected module import duplication issues in test files by standardizing import styles - Improved file operation safety across multiple services by adding try/finally blocks and proper resource management - Enhanced error handling in file operations within gRPC and API route handlers The changes significantly improve code safety by addressing resource leaks, uninitialized variables, and improper error handling patterns identified by CodeQL, while maintaining existing functionality. --- .gitignore | 126 +++++++++++++++----- ai/retry.py | 3 +- services/zc/app/api/v1/routes.py | 4 +- services/zc/app/grpc/wire_servicer.py | 49 ++++---- services/zc/app/services/upload_manager.py | 1 -
