Entry point function that orchestrates a Q&A document updater application, loading configuration, setting up logging, and processing Q&A document updates with comprehensive status handling.

Purpose

This function serves as the main orchestrator for a Q&A document management system. It initializes the application environment by loading configuration files, setting up logging infrastructure, creating a QAUpdater instance, and demonstrating the update workflow for Q&A documents. The function handles multiple update scenarios including successful updates, review requirements, no-update cases, and errors, logging appropriate information for each outcome.

Source Code

def main():
    """Main entry point for the Q&A document updater application."""

    # 1. Load Configuration
    config = ConfigParser()
    config.read('config/config.ini')

    # 2. Setup Logging
    log_level = os.environ.get('LOG_LEVEL', 'INFO').upper()
    log_level = getattr(logging, log_level, logging.INFO)  # Convert string to logging level
    logger = setup_logging(log_level=log_level, log_file=config.get('paths', 'log_file', fallback=None))

    logger.info("Starting Q&A Document Updater...")

    try:
        # 3. Initialize QAUpdater
        qa_updater = QAUpdater(config)

        # 4. Example Usage: Update a specific Q&A document
        question_id = "12345"  # Replace with the actual ID of the Q&A document you want to update
        update_result = qa_updater.update_qa_document(question_id)

        # 5. Process Update Result
        if update_result["status"] == "updated":
            logger.info(f"Q&A document '{question_id}' successfully updated.")
            logger.info(f"New Answer: {update_result['new_answer']}")
            logger.info(f"Reasoning: {update_result['reasoning']}")
            logger.info(f"Changes: {update_result['changes']}")
        elif update_result["status"] == "review_needed":
            logger.warning(f"Q&A document '{question_id}' requires human review.")
            logger.warning(f"Reasoning: {update_result['reasoning']}")
            logger.warning(f"Suggested Answer: {update_result['suggested_answer']}")
        elif update_result["status"] == "no_update_needed":
            logger.info(f"No update needed for Q&A document '{question_id}'.")
            logger.info(f"Reasoning: {update_result['reasoning']}")
        elif update_result["status"] == "error":
            logger.error(f"Error updating Q&A document '{question_id}': {update_result['error_message']}")

    except Exception as e:
        logger.exception("An unexpected error occurred during the application execution.")

    logger.info("Q&A Document Updater finished.")

Return Value

This function does not return any value (implicitly returns None). All results are communicated through logging statements and side effects (file updates, log entries).

Dependencies

• logging
• os
• configparser

Required Imports

import logging
import os
from configparser import ConfigParser
from qa_engine.qa_updater import QAUpdater
from utils.logging_utils import setup_logging

Usage Example

# Ensure config/config.ini exists with required settings
# Example config.ini:
# [paths]
# log_file = logs/qa_updater.log

# Set optional environment variable
import os
os.environ['LOG_LEVEL'] = 'DEBUG'

# Import and run
from your_module import main

if __name__ == '__main__':
    main()

# The function will:
# 1. Load configuration from config/config.ini
# 2. Setup logging based on LOG_LEVEL env var
# 3. Initialize QAUpdater with config
# 4. Update Q&A document with ID '12345'
# 5. Log results based on update status

Best Practices

• Replace the hardcoded question_id '12345' with actual document IDs from your system or implement a loop to process multiple documents
• Ensure config/config.ini exists and is properly formatted before running the function
• Set LOG_LEVEL environment variable appropriately for your environment (DEBUG for development, INFO/WARNING for production)
• Implement proper error handling in the QAUpdater class to ensure meaningful error messages are returned
• Consider adding command-line argument parsing to make question_id configurable instead of hardcoded
• The function catches all exceptions broadly - consider more specific exception handling for production use
• Ensure the log file directory exists or handle directory creation in setup_logging
• Consider implementing a batch processing mode to update multiple Q&A documents in a single run
• Review the update_result dictionary structure to ensure it matches what QAUpdater.update_qa_document returns
• Add monitoring or alerting for 'review_needed' and 'error' statuses in production environments
