Fix: Error Handling for Commit Length in Miner Configuration

[kienn6034]

Bug:

The function incorrectly returns nil when the Git commit length is not equal to 40, potentially causing unclear failures.

Fix:

Correct the error handling to return a specific error when the commit length check fails.

Walkthrough

The update to the config.go file in the Cosmos project involves ensuring that the git commit hash is exactly 40 characters long. If this is not the case, the updated function now provides a clear error message, formatted properly with the newly imported "fmt" package. This change enhances the robustness of the configuration parser by enforcing a validation check on the git commit length.

Changes

File	Summary
cosmos/config/config.go	Imported "fmt" package; updated readConfigFromAppOptsParser to validate git commit length and return a formatted error if invalid.

🐰✨
In the code's garden, fresh changes bloom,
A commit hash check in its costume.
Forty chars, no less, no room for doom,
Ensuring the config's in perfect tune. 🎶

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-tests for this file.
• 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 tests 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 from git and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit tests.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

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.

• 24-24: The import of the "fmt" package is necessary for formatting error messages and is correctly placed in the import block.
• 110-110: The error handling logic for the Git commit length check has been updated to return a specific error message when the length is not 40 characters. This is a good practice as it provides clear feedback to the user.
