Deep Dive into Git

" summary

Shows how Git stores data as objects (blobs, trees, commits) addressed by SHA-1 IDs, with commits as snapshots not diffs and trees referencing file blobs so unchanged files aren’t duplicated. Explains on-disk layout (.git/objects, refs/heads), how HEAD is a symbolic ref and branches are just 41-character pointers, how merges create two-parent commits while fast‑forwards just move pointers, how rebase replays patches, how the index is the cache/staging area, and mentions tools like git-cat-file, git-ls-tree and libgit2 plus a recover script for loose blobs.
