This article provides an in-depth exploration of two core methods for rolling back a Git repository to a specific commit: git reset and git revert. Through analysis of a practical case—needing to roll back a repository with 100 commits to commit 80 and remove all subsequent commits—the article explains in detail how the git reset --hard command works, its usage scenarios, and potential risks. The paper contrasts the fundamental differences between reset and revert: reset directly modifies history by moving the HEAD pointer, suitable for local cleanup, while revert creates new commits to reverse changes, safer but preserving history. Incorporating reference articles, it further elaborates on the dangers of using force push in collaborative environments and how to choose appropriate strategies based on team workflows. The full text includes complete code examples, step-by-step analysis, and best practice recommendations to help developers deeply understand core concepts of version control.

Through detailed code examples and branch diagrams, it explains how both methods affect project history and discusses the use cases and precautions for rebasing. Practical tips for configuring git pull to use rebase are also provided, helping developers choose appropriate workflows based on team collaboration needs.

This article explores methods to determine the branch from which a Git commit originated using its SHA-1 hash. It covers techniques such as searching branch histories with git branch --contains, examining reflogs for commit traces, analyzing merge commits, and using git name-rev. Code examples and best practices are provided to enhance version control workflows, ensuring efficient tracking of commit origins in various scenarios.

This article provides an in-depth exploration of various methods to revert committed files in Git after they have been pushed, with a focus on the preferred safe approach that avoids force-pushing by checking out the file's previous state and creating a new commit. It also analyzes alternative solutions, including using git rm --cached to remove files from the repository and file restoration for specific revisions, and discusses special cases involving sensitive data. Each method is accompanied by detailed code examples and scenario-based explanations to help developers choose the most appropriate solution based on their needs.

This technical article provides an in-depth analysis of push failures in Git workflows when making initial commits to bare repositories. Through examination of a common scenario—cloning an empty bare repository, making a first commit, and encountering 'No refs in common' errors during push—the article uncovers the underlying mechanics of Git's push mechanism. The core issue stems from the absence of shared references between the local repository and the bare repository in its initial state, preventing Git from automatically determining push targets. The article details how the git push --set-upstream origin master command works, and how push.default configuration options (particularly upstream/tracking mode) optimize push behavior. By comparing workflow differences under various configurations, it offers comprehensive technical solutions and best practice recommendations for developers.
