Walkthrough

Walkthrough

The recent update in the pkg/gateway/lb/handler/grpc/handler.go file involves modifying the calculateNum method within the server struct. The primary change is adjusting the logic to handle cases where the ratio is less than or equal to 0.0. This ensures that the calculation is more robust and handles edge cases more effectively.

Changes

File Path	Change Summary
pkg/gateway/lb/handler/grpc/handler.go	Updated calculateNum method to handle ratio <= 0.0 and removed redundant condition for ratio == 0.0.

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 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.

Line range hint 455-462: Refactor calculateNum to handle ratio <= 0.0 more efficiently.

The simplification of the condition to handle ratio <= 0.0 in one clause is a good improvement. It makes the code cleaner and easier to maintain. However, it's crucial to ensure this change is covered by unit tests, especially for edge cases around the value 0.0.
