Important

Add backend status stream endpoint and refactor admin commands to utilize SSE for status updates.

  • Behavior:
    • Adds BackendStatus command to AdminCommand in admin.rs to stream backend status updates.
    • Introduces print_status_stream() in admin.rs to handle streaming of backend status until a specified status is reached.
    • Refactors Connect and Terminate commands in admin.rs to use print_status_stream() for status updates.
  • Client:
    • Exposes sse module in client/mod.rs for public use.
    • Adds backend_status_stream() in PlaneClient in client/mod.rs to initiate SSE requests for backend status updates.
  • Misc:
    • Minor import reordering in admin.rs for better organization.

📝 Walkthrough

Walkthrough

The pull request introduces changes to two primary files: plane/src/admin.rs and plane/src/client/mod.rs. In admin.rs, several enhancements are made to backend status management. A new command, BackendStatus, is added to the AdminCommand enum, enabling users to query the status of a specific backend. The print_status_stream function is introduced to process and print backend status updates from a stream until a specified condition is met. This function improves code reusability by refactoring existing logic related to backend status updates during connection commands. Additionally, the import statements are reorganized to support the new streaming functionality.

In client/mod.rs, the visibility of the sse module is changed from private to public, allowing external access. No other modifications to the logic, error handling, or control flow in the PlaneClient class or its methods are made. The overall functionality of the client remains unchanged, focusing solely on the visibility adjustment of the sse module.


🪧 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.

15-15: Remove unused Stream import

The Stream trait import is unused. However, keep StreamExt as it's required for the .next() method.

-use futures_util::{Stream, StreamExt};
+use futures_util::StreamExt;

368-371: Consider adding flexibility to BackendStatus command

The command currently streams until Terminated status. Consider adding an optional --until-status flag to allow users to specify the target status, similar to how it's used in the Connect command (which stops at Ready).

Example enhancement:

 BackendStatus {
     backend: BackendName,
+    #[clap(long)]
+    until_status: Option<BackendStatus>,
 }

Then in the implementation:

-print_status_stream(stream, BackendStatus::Terminated).await;
+print_status_stream(stream, until_status.unwrap_or(BackendStatus::Terminated)).await;

160-162: LGTM! New command follows existing patterns

The BackendStatus command is well-structured and consistent with other command variants.


172-187: Well-structured streaming implementation with good reusability

The function effectively handles status streaming with:

  • Clear termination condition
  • Consistent output formatting
  • Good reusability across commands
