This article delves into the core mechanisms of copying files while preserving history in Git. Unlike version control systems such as Subversion, Git does not store explicit file history information; instead, it manages changes through commit objects and tree objects. The article explains in detail how Git uses heuristic algorithms to detect rename and copy operations, enabling tools like git log and git blame to trace the complete history of files. By analyzing Git's internal data structures and working principles, we clarify why Git can effectively track file history even without explicit copy commands. Additionally, the article provides practical examples and best practices to help developers manage file versions in complex projects.

This article thoroughly examines a common yet perplexing issue in Git distributed version control systems: when executing the git pull command, the repository status displays "Already up-to-date," but the actual files in the working directory remain unsynchronized. Through analysis of a typical three-repository workflow scenario (bare repo as central storage, dev repo for modifications and testing, prod repo for script execution), the article reveals that the root cause lies in the desynchronization between the local repository's remote-tracking branches and the actual state of the remote repository. The article elaborates on the core differences between git fetch and git pull, highlights the resolution principle of the combined commands git fetch --all and git reset --hard origin/master, and provides complete operational steps and precautions. Additionally, it discusses other potential solutions and preventive measures to help developers fundamentally understand and avoid such issues.
