Summary of Changes

Hello @ehsavoie, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refactors the handling of the historyLength parameter across the application, primarily by converting it from a nullable Integer to a primitive int with a default value of 0. This change streamlines the logic for retrieving task history, ensuring that a historyLength of 0 correctly fetches the complete history and eliminates the need for explicit null checks, leading to more robust and predictable behavior.

Highlights

  • Type Change for historyLength: The historyLength parameter in TaskQueryParams and related methods has been changed from a nullable Integer to a primitive int, ensuring it always has a value and simplifying null checks.
  • Default Value Handling: The default value for historyLength is now explicitly set to 0. When historyLength is 0 or less, the system will return the full task history, addressing previous inconsistencies.
  • Removal of Null Checks: Code paths that previously checked for historyLength != null have been removed or updated, as the parameter is now a primitive int and cannot be null.
  • API and Test Adjustments: Client and server-side logic, including REST and gRPC transports, have been updated to reflect the int type for historyLength. Corresponding test cases have also been adjusted to pass 0 instead of null.

Code Review

This pull request correctly addresses the handling of historyLength by changing its type from Integer to int and defaulting it to 0. The logic is updated across the codebase to return the full history when historyLength is 0. The changes are consistent and well-implemented. I have one suggestion to simplify the logic in DefaultRequestHandler for improved efficiency and readability.
