Walkthrough

The changes introduced in this pull request focus on enhancing the error handling within the QueryAsync method of the Main class in the Flow.Launcher.Plugin.Program namespace. A try-catch block has been added to capture OperationCanceledException, allowing the method to return an empty results list when an operation is canceled. This modification improves the reliability of the method during cancellation scenarios without altering the overall structure or functionality of the class.

Changes

File Path	Change Summary
Plugins/Flow.Launcher.Plugin.Program/Main.cs	Added a try-catch block in QueryAsync to handle OperationCanceledException and return an empty results list. Utilized emptyResults for consistent return value upon cancellation.

Poem

🐰 In the land of code where bunnies play,
A catch was added to save the day.
When operations pause and take a rest,
An empty list now does its best.
With every hop, we handle with grace,
In the world of plugins, we find our place! 🌟

🪧 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>, please review it.
  • 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 gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @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.

76-80: Consider adding logging for cancellations.

While the cancellation handling is correct, adding debug logging could help track the frequency and context of cancellations.

 catch (OperationCanceledException)
 {
     // Fix #3091: System.OperationCanceledException Issue
+    Log.Debug($"|Flow.Launcher.Plugin.Program.Main.QueryAsync|Operation was canceled");
     return emptyResults;
 }

81-82: Remove unnecessary empty line.

The empty line at 81 can be removed to maintain consistent spacing.

63-80: LGTM! Good approach to handling cancellation.

The implementation correctly handles OperationCanceledException from parallel LINQ operations and returns an empty result list, which is a good practice. The use of a pre-allocated empty list is also efficient.
