Pull Request - Refactor FlightRecorderInputStream Class

Summary of the Change

This pull request refactors the FlightRecorderInputStream class by simplifying the analyzeCrash method. The method, which previously included complex logic for thread creation, has been refactored to delegate the thread creation into a new private method called createDiagnosisThread. This change improves the method's readability and maintainability, without altering its functionality.

Code Smell Identified:

• The analyzeCrash method was identified as having a high level of complexity, with the logic for thread creation embedded directly in the method.

Refactoring Method:

• Extract Method: The logic for creating and initializing the thread was extracted into a new method called createDiagnosisThread to simplify the analyzeCrash method.

Benefits:

• Readability: The analyzeCrash method is now cleaner and more focused on its primary responsibilities.
• Reusability: The new createDiagnosisThread method can be reused if thread creation is needed elsewhere in the code.

Testing Done

• Manual Testing:

  • The refactor has been manually tested by verifying that the functionality of the FlightRecorderInputStream class remains intact.
  • The thread creation behavior has been preserved, and the refactor improves code structure without altering functionality.

• Automated Testing:

  • No new automated tests were added as part of this refactor. However, the code was exercised manually to confirm that the changes did not break existing functionality.

Proposed Changelog Entries

• Simplified the analyzeCrash method by extracting thread creation logic into a new helper method, createDiagnosisThread.
