Understanding the git commit-tree Command and Commit Visibility

When working with Git, you might find yourself facing challenges, especially as you learn the ins and outs of version control. One common issue new users encounter relates to visibility of commits created through specific Git commands. In this guide, we'll explore a peculiar situation where a commit does not appear in the logs after using the git commit-tree command.

The Problem: Invisible Commit

As a new user attempting to experiment with Git, you might find that after creating a new commit using git commit-tree, it does not show up when you invoke the git log command. For instance, after executing:

One may expect the commit to appear in the history, but instead, the output from git log --all --decorate --oneline --graph shows only the previous commit.

Why is This Happening?

Floating Commits: When you create a commit using git commit-tree, if you do not update a branch reference to point to the newly created commit, it becomes a "floating commit." This means it's part of the repository but isn't accessible through any branch.

Wrong Case Reference: Using head instead of HEAD will cause errors in Git since it is case-sensitive. While this might not be an issue on some operating systems like Windows due to their case-insensitivity, it’s best practice to use the correct case to avoid confusion.

Implementing the Solution: Correctly Commit Your Changes

Step 1: Make Your Commit

First, create your new commit as you initially attempted. It’s important to spell HEAD correctly to avoid potential errors. Here’s a refined version of what you are trying to do:

Step 2: Update the Branch Reference

To ensure that the branch you are working on points to the new commit, you need to update the reference. This can be done with the following command:

Alternatively, you can combine the commit creation and updating the branch reference into one command as follows:

Step 3: Review the Commits

After updating your branch with the new commit, you can check your commit history to confirm the changes:

This should now display both commits as expected, showing the newly added "orange" commit in the repository history.

Tip: Handling Input Correctly

When entering messages or managing workflows that involve standard input, remember:

Use CTRL-D on Linux or CTRL-Z on Windows to finalize input.

Understand how Git interacts with inputs to avoid confusion when running commands.

Conclusion

By understanding the intricacies of Git commands and ensuring that you correctly reference commits and branch heads, you can streamline your version control and avoid confusion when navigating your commit history. It’s always beneficial to experiment and learn through practice, but knowing how to manage commits properly will undoubtedly make your workflow smoother and your learning experience richer.

If you're facing similar issues, remember:

Always check for case sensitivity.

Update branch references after creating floating commits.

Handle inputs clearly in your commands.

Happy coding!
