Cleans up logs and returns the current peer list if it fails incremental fetches from contract (e.g. you get the first response, but fail on the second).

Walkthrough

Walkthrough

The changes in the ArIODataSource class focus on improving the error handling and control flow within the updatePeerList method. The try-catch block has been refined to specifically target the asynchronous call for fetching gateways, enhancing error management. Additionally, the logging mechanism for the updated peer list has been improved to include the keys of the peers object, thereby providing clearer debug information while maintaining the overall logic flow.

Line range hint 87-123: LGTM! The changes improve error handling and logging.

The changes in this code segment are well-aligned with the learning from PR #165 to handle errors for paginated requests by logging the error and continuing to process the remaining pages. Moving the try-catch block to specifically wrap the asynchronous call to fetch gateways ensures that if an error occurs during the fetching, it logs the error and breaks out of the loop without affecting the overall structure of the peer list update process. This improves the robustness of the error handling.

Additionally, the enhanced error logging, which now includes the error message and stack trace, provides more context for debugging. The improved logging of the updated peer list, which includes the keys of the peers object, enhances the debug output by providing more context about the updated peer list.

Overall, these changes contribute to better error handling and improved logging for easier debugging and understanding of the code's behavior.

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.
