Git Commit Basics

Understanding Git Commits

Git commits are fundamental snapshots of your project at specific points in time. Each commit represents a set of changes to your repository, capturing the state of your files and providing a historical record of your project's development.

Key Characteristics of Git Commits

Creating a Commit

## Initialize a new Git repository
$ git init

## Stage files for commit
$ git add .

## Create a commit with a descriptive message
$ git commit -m "Initial project setup"

Commit Best Practices

1. Write clear, concise commit messages
2. Commit frequently
3. Keep commits focused on a single logical change
4. Use meaningful branch names

Exploring Commit History

## View commit log
$ git log

## View detailed commit information
$ git show <commit-hash>

At LabEx, we recommend mastering these commit basics to effectively manage your project's version control and collaboration workflow.

Tracking Lost Commits

Understanding Commit Loss

Commits can become "lost" in various scenarios, such as:

• Accidental branch deletion
• Incorrect reset operations
• Rebasing or force pushing

Git Reflog: Your Commit Recovery Companion

## View reflog to track recent commit history
$ git reflog

## Example reflog output
## 8a5f3d4 HEAD@{0}: commit: Add new feature
## 2b4c9e1 HEAD@{1}: checkout: moving from develop to main

Commit Recovery Techniques

1. Recovering Deleted Branches

## Find the last commit of the deleted branch
$ git reflog show <branch-name>

## Restore the deleted branch
$ git branch <branch-name> <commit-hash>

2. Recovering Lost Commits

Advanced Recovery Strategies

## Find lost commits not referenced by any branch
$ git fsck --lost-found

## Recover a specific lost commit
$ git merge <commit-hash>

Preventing Commit Loss

1. Use descriptive branch names
2. Avoid force pushing
3. Regularly backup important branches
4. Use Git GUI tools for complex operations

LabEx Pro Tip

Always use git reflog as your first line of defense when tracking down lost commits. It maintains a log of all reference updates in your local repository.

Common Scenarios of Commit Loss

• Accidental git reset --hard
• Unintended branch deletion
• Complicated merge conflicts
• Experimental rebasing

Commit Recovery Techniques

Comprehensive Commit Recovery Strategies

1. Using Git Reflog

## View reflog to track commit history
$ git reflog

## Recover a specific commit
$ git reset --hard <commit-hash>

2. Cherry-Pick Method

## Identify the lost commit hash
$ git log --all --full-history | grep "lost commit message"

## Recover the specific commit
$ git cherry-pick <lost-commit-hash>

Advanced Recovery Techniques

3. Git FSck Recovery

## Scan for dangling commits
$ git fsck --lost-found

## Inspect recovered commits
$ ls .git/lost-found/

## Restore specific commit
$ git merge <commit-hash>

Preventing Commit Loss

1. Regular backups
2. Careful branch management
3. Use descriptive commit messages
4. Understand Git operations

LabEx Recommended Workflow

## Always create a backup branch before complex operations
$ git branch backup-branch

## Perform risky operations
$ git rebase or git reset

Recovery Scenario Examples

Accidental Hard Reset

## Recover after unintended hard reset
$ git reflog
$ git reset --hard <previous-commit-hash>

Deleted Branch Recovery

## Find deleted branch commit
$ git fsck --lost-found

## Recreate the branch
$ git branch recovered-branch <commit-hash>

Key Recovery Principles

• Always maintain a calm approach
• Use systematic recovery methods
• Understand each Git command's implications
• Regularly practice recovery techniques

Summary

Understanding how to find missing Git commits is crucial for maintaining a robust version control workflow. By mastering techniques like using reflog, examining dangling commits, and employing recovery strategies, developers can effectively restore lost work and ensure the continuity of their project's development process.
