Summary of Changes
Hello @pankaj-bind, 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 significantly enhances the robustness and reliability of the TaskManager by introducing critical input validation for task identifiers during object initialization. This proactive measure prevents potential silent failures and inconsistencies that could arise from malformed or invalid task_id inputs, thereby improving the overall stability of task management operations.
Highlights
- Input Validation: Implemented robust input validation for the
task_idparameter within theTaskManager's__init__method insrc/a2a/server/tasks/task_manager.py. This ensures thattask_idis a non-empty string, raising aValueErrorif an invalid value (e.g., empty string, non-string type) is provided. - Unit Testing: Added a new unit test case,
test_task_manager_invalid_task_id, totests/server/tasks/test_task_manager.py. This test verifies that theTaskManagercorrectly raises aValueErrorwhen initialized with invalidtask_idvalues, such as an empty string or an integer.

Code Review
This pull request introduces important input validation for task_id in the TaskManager, which enhances the robustness of the class. The implementation is correct and is accompanied by a new unit test. My feedback focuses on improving the readability of the validation logic and making the new test more maintainable and comprehensive by using pytest.mark.parametrize.

Previously, the
TaskManagerclass ina2a/server/tasks/task_manager.pydid not perform any validation on thetask_idduring initialization. This could lead to silent failures or inconsistencies in task storage if an invalid ID (such as an empty string) was provided.Impact
Adding this validation improves the robustness of the
TaskManagerand prevents downstream errors in task management, especially for database or in-memory stores.Fix
In
a2a/server/tasks/task_manager.py, a check has been added to the__init__method of theTaskManagerto validate thetask_id. It now ensures that if atask_idis provided, it is a non-empty string. If the validation fails, aValueErroris raised.A corresponding unit test has been added to
tests/server/tasks/test_task_manager.pyto verify that the validation works as expected.
