Git's complexity often stems from misunderstandings related to its object model, specifically the misconception that commits are diffs rather than snapshots. This article clarifies that Git commits are immutable snapshots representing a repository's state at a specific time, while diffs are dynamically generated comparisons between these snapshots. It explains Git's object model, including blobs for file contents, trees for directory listings, and commits for entire snapshots. Branches serve as pointers to commits, facilitating navigation and changes without directly referencing object IDs. The text explores how commands like git cherry-pick and git rebase work by replaying commit diffs rather than moving commits. Additionally, it discusses Git's dynamic rename detection during diff calculations, emphasizing that Git does not inherently track renames but infers them through comparisons. Overall, this understanding of Git's internal workings aids in navigating and using Git more effectively.
