(DAL) writeControl

[nick-bisonai]

Description

Send disconnection message to the client through writeControl

reference

In the WebSocket protocol, a close message is a special control message used to indicate that the endpoint wishes to close the connection. It is an orderly and graceful shutdown process, allowing the peer to send a corresponding close message in response.

After sending a close message, the application typically continues to receive data until it receives a close message from the peer. This ensures that both sides have the opportunity to complete any pending data exchange, adhering to the normal termination process of WebSockets.

Walkthrough

Walkthrough

The recent update improves the Start method of the Hub struct in the api package by enhancing the client disconnection process. Instead of merely closing client connections, the new implementation sends a close message to the client using conn.WriteControl, providing a smoother and more graceful disconnection. This change strengthens WebSocket handling and ensures clients are properly notified before their connections are terminated.

Changes

Files	Change Summary
node/pkg/dal/api/hub.go	Modified the Start method in the Hub struct to send a close message to clients before closing connections. Introduced a one-second timeout for the control message, improving disconnection handling.

Poem

In the web's gentle dance,
A rabbit hops with a glance.
"Close with care," it now sings,
As graceful disconnection brings.
With a wave and a wink,
We improve, not just shrink! 🐇✨

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.
