djust the location of method called  [closeTransports();] (#1442)

Motivation:

there are two bugs in the AbstractCluster.java

  1. variable named [oldProviderGroup] will be changed because of the method [addressHolder.updateProviders(providerGroup);], which will not execute method [ closeTransports();]

  2. the method of [closeTransports();] should not be contain in the [LOGGER.isWarnEnabled(consumerConfig.getAppName())]

Modification:

  1. I use a boolean tmp named [isOldProviderGroupEmpty], avoid the change of [oldProviderGroup]

Result:

Fixes #1442

Walkthrough

The pull request modifies the updateProviders method in the AbstractCluster class by introducing a boolean variable to enhance code readability. This variable stores the result of checking if the old provider group is empty, reducing redundant method calls. The overall logic and control flow of the method remain unchanged, ensuring consistent behavior while improving clarity and maintainability.

Poem

🐰 In the code where clusters roam,
A boolean shines, a clearer home.
No more calls that waste the day,
Readability leads the way!
With each provider's graceful dance,
Our logic finds a second chance! 🌟

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.
