# Description of Changes **What was changed:** - **Configuration Updates:** Replaced all calls to `GeneralUtils.saveKeyToConfig` with the new `GeneralUtils.saveKeyToSettings` method across multiple classes (e.g., `LicenseKeyChecker`, `InitialSetup`, `SettingsController`, etc.). This update ensures consistent management of configuration settings. - **File Path and Exception Handling:** Updated file path handling in `SPDFApplication` by creating `Path` objects from string paths and logging these paths for clarity. Also refined exception handling by catching more specific exceptions (e.g., using `IOException` instead of a generic `Exception`). - **Analytics Flag and Rate Limiting:** Changed the analytics flag in the application properties from a `String` to a `Boolean`, and updated related logic in `AppConfig` and `PostHogService`. The rate-limiting property retrieval in `AppConfig` was also refined for clarity. - **YAML Configuration Management:** Replaced the previous manual, line-based YAML merging logic in `ConfigInitializer` with a new `YamlHelper` class. This helper leverages the SnakeYAML engine to load, update, and save YAML configurations more robustly while preserving comments and formatting. **Why the change was made:** - **Improved Maintainability:** Consolidating configuration update logic into a single utility method (`saveKeyToSettings`) reduces code duplication and simplifies future maintenance. - **Enhanced Robustness:** The new `YamlHelper` class ensures that configuration files are merged accurately and safely, minimizing risks of data loss or format corruption. - **Better Type Safety and Exception Handling:** Switching the analytics flag to a Boolean and refining exception handling improves code robustness and debugging efficiency. - **Clarity and Consistency:** Standardizing file path handling and logging practices enhances code readability across the project. **Challenges encountered:** - **YAML Merging Complexity:** Integrating the new `YamlHelper` required careful handling to preserve existing settings, comments, and formatting during merges. - **Type Conversion and Backward Compatibility:** Updating the analytics flag from a string to a Boolean required extensive testing to ensure backward compatibility and proper functionality. - **Exception Granularity:** Refactoring exception handling from a generic to a more specific approach involved a detailed review to cover all edge cases.
