PR Type

Enhancement, Bug fix

---

Description

• Added error handling to the _get_system_user_tokens method in the TokenEncoder class
• Imported get_logger function from pr_agent.log module for logging errors
• Wrapped the token counting logic in a try-except block to catch and handle exceptions
• In case of an exception, the method now logs the error and returns 0 tokens instead of potentially crashing
• This change improves the robustness of the token counting process and prevents potential crashes due to unexpected errors

PR Code Suggestions ✨

Category	Suggestion	Score
Error handling	Use more specific exception handling to improve error diagnosis and handling Consider using a more specific exception type instead of catching all exceptions. This will make it easier to debug and handle specific error cases. pr_agent/algo/token_handler.py [67-76] try: environment = Environment(undefined=StrictUndefined) system_prompt = environment.from_string(system).render(vars) user_prompt = environment.from_string(user).render(vars) system_prompt_tokens = len(encoder.encode(system_prompt)) user_prompt_tokens = len(encoder.encode(user_prompt)) return system_prompt_tokens + user_prompt_tokens -except Exception as e: +except (jinja2.exceptions.TemplateError, UnicodeEncodeError) as e: get_logger().error(f"Error in _get_system_user_tokens: {e}") return 0 Apply this suggestion Suggestion importance[1-10]: 7 Why: Using specific exceptions can improve error handling and debugging, but the current generic exception handling is not incorrect and may be intentional for broader error catching.	7
Logging	Add a warning log when returning 0 tokens due to an error Consider adding a warning log when returning 0 tokens, as this might indicate an unexpected situation that needs attention. pr_agent/algo/token_handler.py [74-76] except Exception as e: get_logger().error(f"Error in _get_system_user_tokens: {e}") + get_logger().warning("Returning 0 tokens due to an error, which might affect further processing.") return 0 Apply this suggestion Suggestion importance[1-10]: 6 Why: Adding a warning log provides more context about the error situation, which can be helpful for debugging, but it's not a critical improvement.	6
Optimization	Optimize the try-except block by moving constant initializations outside Consider moving the Environment creation outside of the try-except block, as it's not likely to raise an exception and doesn't depend on the function parameters. pr_agent/algo/token_handler.py [67-73] +environment = Environment(undefined=StrictUndefined) try: - environment = Environment(undefined=StrictUndefined) system_prompt = environment.from_string(system).render(vars) user_prompt = environment.from_string(user).render(vars) system_prompt_tokens = len(encoder.encode(system_prompt)) user_prompt_tokens = len(encoder.encode(user_prompt)) return system_prompt_tokens + user_prompt_tokens Apply this suggestion Suggestion importance[1-10]: 5 Why: Moving the Environment creation outside the try-except block is a minor optimization that slightly improves code structure, but it doesn't significantly impact functionality or performance.	5
