Walkthrough

The recent update introduces a safeguard within the heatmapPathsDense function to ensure stability. Before assigning fillPath values, the function now checks for the existence of fills and fillPaths and their indices. If these are not defined, the iteration is safely skipped, preventing potential errors that could arise from trying to access undefined properties.

Changes

File	Summary
public/app/plugins/.../heatmap/utils.ts	Added conditional checks for fills and fillPaths before fillPath assignments.

Poem

In the garden of code, where the data plots bloom,
A vigilant Rabbit guards against doom.
With each conditional check, it hops and ensures,
That no undefined path leads to bugs that it cures. 🐇💻✨

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-tests for this file.
• 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 tests 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 from git and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit tests.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

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)

• 725-732: The added conditional check in heatmapPathsDense function is a good defensive programming practice to avoid potential crashes when fills or fillPaths are undefined. This aligns with the PR objective to fix the sentry heatmap crash by ensuring that the function does not attempt to process undefined or invalid data.
