|git| LFS Extension

Git Large File Storage (or LFS) is a new, open-source extension to Git that aims to improve handling of large files. It does this by replacing large files in your repository—such as graphics and videos—with simple text pointers. RhodeCode Server includes an embedded LFS object store server, allowing storage of large files without the need for an external object store. Git LFS is disabled by default, globally, and for each individual repository.

Note

RhodeCode implements V2 API of Git LFS. Please make sure your git client is using the latest version (2.0.X recommended) to leverage full feature set of the V2 API.

Enabling Git LFS

Git LFS is disabled by default within RhodeCode Server.

To enable Git LFS Globally:

  • Go to :menuselection:`Admin --> Settings --> VCS`
  • Scroll down into Git settings
  • Tick Enable lfs extension
  • Save your settings.

Those settings apply globally to each repository that inherits from the defaults You can leave lfs extension disabled globally, and only enable it per repository that would use the lfs.

Note

You might want to adjust the global storage location at that point, however we recommend leaving the default one created.

Installing and using the Git LFS command line client

Git LFS aims to integrate with the standard Git workflow as seamlessly as possible. To push your first Git LFS files to an existing repository Download and install the git-lfs command line client Install the Git LFS filters:

git lfs install

This adds the following lines to the .gitconfig file located in your home directory:

[filter "lfs"]
    clean = git-lfs clean %f
    smudge = git-lfs smudge %f
    required = true

The above change applies globally, so it is not necessary to run this for each repository you work with. Choose the file types you would like LFS to handle by executing the git lfs track command. The git lfs track command creates or updates the .gitattributes file in your repository. Change to your cloned repository, then execute git add to ensure updates to the .gitattributes are later committed:

git lfs track "*.jpg"
git add .gitattributes

Add, commit, and push your changes as you normally would:

git add image.jpg
git commit -m "Added an image"
git push

When pushed, the Git tree updates to include a pointer to the file actual file content. This pointer will include the SHA256 hash of the object and its size in bytes. For example:

oid sha256:4fa32d6f9b1461c4a53618a47324ee43e36ce7ceaea2ad440cc811a7e6881be1
size 2580390

The object itself will be uploaded to a separate location via the Git LFS Batch API. The transfer is validated and authorized by RhodeCode server itself.

If give repository has Git LFS disabled, a proper message will be sent back to the client and upload of LFS objects will be forbidden.
