Walkthrough

The changes in this pull request focus on enhancing error handling within the nodedb.go and nodedb_test.go files. In nodedb.go, error messages have been simplified by replacing formatted errors with standard error instantiations using errors.New. The nodedb_test.go file has been updated with new test cases, refined assertions, and benchmarking functions to improve the validation of error handling and storage version management. Overall, the modifications aim to standardize error handling practices and enhance the robustness of the nodeDB functionality.

🐇 In the code where errors lay,
A hop to fix them, come what may.
With errors.New, we simplify,
In tests and nodes, we reach for the sky!
So let’s refine and make it bright,
A rabbit’s joy in code’s delight! 🐇

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.
