Git Internals

Content of .git folder

Git stores snapshots (exact content of the files) at the point of a commit.

ls .git

The content is stored in the objects sub-directory. There are 4 kinds of objects:

used for storing the contents of a single file
contains references to other blobs or subtrees
contains reference to another tree object and some other information (author, committer etc.)
Another reference to a commit object

VFS for Git

VFS for Git is a virtualized filesystem used to bypass assumptions about repository size, allowing Git repositories to scale up to large repositories.

With GVFS, an initial clone downloads a set of pack-files containing only commits and trees. These objects are sufficient for generating a view of the working directory, and examining the commit history with git log.

GVFS allows dynamically downloading objects as needed.
