Understanding GitLens Behavior: How to Recover Your Newer Commits After Switching to an Older Commit

If you've ever found yourself in a situation where you accidentally switched to an older commit using the GitLens extension in Visual Studio Code (VSCode), you're not alone. Many developers face panic when they execute this action only to discover that their newer commits seem to have disappeared. Fear not! While this situation can be alarming, all your commits are still intact. In this guide, we will demystify this issue and guide you on how to recover your newer commits safely.

The Problem: Where Did My Newer Commits Go?

When you used GitLens to switch to an older commit, you likely expected to return to your current working state afterward. However, running the command git log now shows only the logs of your commits up to the point of that older commit. This can be a confusing and stressful experience, especially when you've recently made significant changes to your code.

What Happened?

When you switched to a specific commit, you entered a state known as detached HEAD mode. In this state, you are no longer on your main branch, which means that while you can explore the history of your commits, you won't see the newer commits that occurred in your original branch.

The Solution: Reattaching the HEAD

What Is HEAD?

In Git, HEAD is a special pointer that indicates your current working branch or commit:

Current Commit: When you reference HEAD, you're pointing to the latest commit of the current branch.

Branch Name: If you're on a branch, HEAD can also reference the branch name.

When you switched to the older commit, HEAD became detached from your branch. To recover your newer commits, you will need to "reattach" HEAD to your main branch.

Step-by-Step Recovery Process

Identify Your Main Branch: First, make sure you know the name of your main branch. It could be main or master, depending on your configuration.

Reattach HEAD:
Use the following command to switch back to your main branch (replace main with your branch name if different):

Verify Your Commits:
After switching back, run:

You should now see your newer commits, including the most recent changes you made before switching.

Alternative Commands to View All Commits

If you wish to explore more about the commits beyond your current branch’s log, you can use the following commands:

Conclusion: Understanding Git to Feel Confident

Getting familiar with how Git manages commits and branches is crucial to avoid losing track of your work. It’s important to understand that your commits are safe even if they don’t appear in your current view after switching commits. The detached HEAD state may seem daunting, but with the commands outlined above, you can effortlessly navigate back to your original state and view all your progress.

Remember, the magic of Git is its ability to maintain a history of your work, allowing you to explore any previous commits while also keeping your recent changes intact. So, the next time you encounter this issue, you will know exactly how to recover!

Happy coding!
