PR Feedback

• 💡 General suggestions: The PR seems to be well-structured and addresses several important issues in the project. However, it would be beneficial to ensure that all changes are adequately tested. Additionally, it would be helpful to include more detailed comments in the code to explain the purpose of the changes, especially for complex operations.

• 🤖 Code feedback:

  • relevant file: database_utils.py
    suggestion: Consider using a context manager (with statement) when opening files. This will ensure that the file is properly closed after it is no longer needed, which is not only good practice but also helps prevent resource leaks. [important]
    relevant line: hash = hashlib.md5(open(file,'rb').read()).hexdigest()

  • relevant file: oui.py
    suggestion: It's recommended to handle exceptions more specifically rather than using a general exception. This can help identify and handle potential issues more effectively. [medium]
    relevant line: except requests.exceptions.RequestException as e:

  • relevant file: wifi_db.py
    suggestion: It's recommended to avoid hard-coding values like '2' in the code. Instead, consider defining a constant at the beginning of your script or in a configuration file. This makes it easier to manage and modify these values. [medium]
    relevant line: if current_time - modification_time < 2 * 60 * 60:

  • relevant file: wifi_db_database.sql
    suggestion: It's recommended to add a unique constraint to the hashMD5 column in the Files table. This will ensure that the MD5 hashes of the files are unique and prevent potential issues with duplicate hashes. [important]
    relevant line: hashMD5 TEXT NOT NULL,
