Walkthrough

This update introduces enhancements for handling computation stop requests within the ManagerClient. Key changes include a new response message structure for the StopComputation operation, improved error handling, and event publication for success or failure scenarios in the service. Additionally, the test suite has been refined to better simulate real-world conditions, ensuring more effective testing of the Stop functionality.

Changes

Files Change Summary
manager/api/grpc/client.go Modified Process method to improve error handling and response structure for stopping computations.
manager/manager.proto Introduced StopComputationResponse message and updated ClientStreamMessage to include it.
manager/service.go Added event publication for the Stop method to notify success and failure.
manager/service_test.go Enhanced TestStop function with mocks, logging, and event channel for improved testing.

Tips

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai generate interesting stats about this repository and render them as a table.
    • @coderabbitai show all the console.log statements in this repository.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

CodeRabbit Commands (invoked as PR comments)

  • @coderabbitai pause to pause the reviews on a PR.
  • @coderabbitai resume to resume the paused reviews.
  • @coderabbitai review to trigger an incremental review. This is useful when automatic reviews are disabled for the repository.
  • @coderabbitai full review to do a full review from scratch and review all the files again.
  • @coderabbitai summary to regenerate the summary of the PR.
  • @coderabbitai resolve resolve all the CodeRabbit review comments.
  • @coderabbitai configuration to show the current CodeRabbit configuration for the repository.
  • @coderabbitai help to get help.

Additionally, you can add @coderabbitai ignore anywhere in the PR description to prevent this PR from being reviewed.

CodeRabbit Configuration File (.coderabbit.yaml)

  • You can programmatically configure CodeRabbit by adding a .coderabbit.yaml file to the root of your repository.
  • Please see the configuration documentation for more information.
  • If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: # yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json

manager/manager.proto (2)

24-28: New message StopComputationResponse added.

The new message structure provides detailed feedback for stopping computations, which is a valuable addition for better communication and error handling.


62-62: Field stopComputationRes added to ClientStreamMessage.

The integration of StopComputationResponse into ClientStreamMessage enhances the message framework by allowing clients to receive detailed responses related to computation stops.

manager/api/grpc/client.go (4)

76-78: New response message structure for StopComputation.

The new response message structure for StopComputation includes the computation ID, which is crucial for identifying the computation being stopped.


80-87: Improved error handling for ErrNotFound.

The error handling for ErrNotFound is well-implemented, ensuring that a clear message is sent back to the client and the computation is marked as not stopped.


88-93: Streamlined error handling for other errors.

The error handling for other errors is consistent and ensures that the client receives a detailed error message.


95-96: Success response for stopped computation.

The response correctly indicates success when a computation is successfully stopped, enhancing the clarity of the communication protocol.

manager/service_test.go (3)

127-130: Improved test setup with mock components.

The introduction of mock components for the provider and VM enhances the test's control over interactions, allowing for more precise validation of behavior.


163-168: Enhanced context for managerService in tests.

The inclusion of a logger and events channel in the managerService struct provides a more realistic context for testing, improving the test's robustness.


192-195: Added cleanup step for eventsChan.

The cleanup step for the eventsChan ensures test isolation and prevents side effects, which is crucial for reliable test results.

manager/service.go (2)

170-170: Verify the placement of the success defer statement.

Ensure that the defer statement for the success event is placed appropriately to reflect the intended logic. It should be placed after the computation is successfully stopped and removed from the map.


177-177: LGTM! Use of defer for failure event is appropriate.

The defer statement for the failure event is well-placed to ensure the event is published if the computation ID is not found.
