While debugging the concurrency issues I noticed most of these collections were mostly unused and could be initialized only when necessary.

Summary by CodeRabbit

Walkthrough

Walkthrough

The recent update focuses on enhancing the ShellScope class in OrchardCore by making initialization of private fields lazy and nullable. This change improves null safety and robustness in handling shared items and callbacks. The modifications are geared towards better management of scope lifecycle events and error handling.

Changes

File Path Change Summary
.../Shell/Scope/ShellScope.cs Updated private fields to be nullable and uninitialized by default. Adjusted methods to handle potential null references more robustly, enhancing the management of shared items, callbacks, and lifecycle events.

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.

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.
