This prevents a goroutine leak by the minio client from happening.
I found this issue because a data retrieval endpoint kept it's minio goroutine alive.
Then I stumbled upon minio/minio-go#1508 and saw the fiber wrapper didn't close the object!

Walkthrough

The pull request introduces a minor but important change in the MinIO storage implementation. A new defer object.Close() statement is added to the Get method of the Storage struct, which ensures proper resource management by automatically closing the retrieved object after its use. This change helps prevent potential resource leaks and improves the overall robustness of the object retrieval process.

minio/minio.go Added defer object.Close() to the Get method to ensure proper object resource cleanup

Poem

🐰 A Rabbit's Ode to Resource Care

In MinIO's realm of bytes and store,
A defer statement opens a new door
Close the object, set it free
No leaks shall escape, thanks to me!
Resource management, clean and bright ✨

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.
