Ensure proper integration ofparseQueryindo_GET.The integration of the
parseQueryfunction into thedo_GETmethod looks correct. However, consider the following:
Error Handling: Ensure that any exceptions raised by
parseQueryare properly handled. SinceparseQueryalready captures exceptions, this is likely sufficient, but verify that no additional handling is needed indo_GET.Logging: The logging statement effectively logs the parsed query. Ensure that sensitive information is not logged, especially if the query parameters may contain PII.
Performance: The use of
parseQuerysimplifies thedo_GETmethod, promoting modularity and maintainability, which is a positive change.Overall, the refactor enhances the clarity and maintainability of the code.

Improve error handling and performance in parseQuery.
-
Error Handling: The function currently captures all exceptions and logs them using Sentry. While this is useful for debugging, it might be beneficial to handle specific exceptions, such as
ValueError, which can occur if the query string is malformed. This would allow for more precise error reporting and potentially different handling strategies for different errors. -
Performance Optimization: The current implementation splits the path and query string multiple times. This can be optimized by using Python's
urllib.parsemodule, which is designed for parsing URLs and query strings efficiently. Here's a suggestion:from urllib.parse import urlparse, parse_qs def parseQuery(path): """ Parses the query string from the URL path and returns a dictionary of key-value pairs. """ try: queryDict = parse_qs(urlparse(path).query) return {k: v[0] for k, v in queryDict.items()} except Exception as e: capture_exception(e) return {}
This refactor uses urlparse and parse_qs to handle the parsing, which is more robust and efficient.

4-8: Test case for empty path looks good.The test correctly verifies that an empty path returns an empty dictionary.
10-13: Test case for path without query parameters is correct.The test accurately expects an empty dictionary for a path with no query parameters.
15-18: Test case for single query parameter is valid.The test correctly expects a dictionary with the single query parameter parsed.
20-23: Test case for multiple query parameters is accurate.The test correctly expects a dictionary with all query parameters parsed.
25-28: Test case for special characters in query parameters is correct.The test accurately expects the special characters to be decoded in the result.
30-33: Test case for malformed query string is appropriate.The test correctly expects the function to parse only the valid parts of the query string.
