A new version of Git LFS, the open-source Git extension for versioning large files, is now available. Git LFS v2.5.0 comes with three new migration modes, a handful of bug fixes, and more.
With v2.5.0, you can use the
git lfs migrate command in a few new ways.
Sometimes repositories can get into a broken state when large files that should have been committed with Git LFS aren’t. If your file is over 100 MB, you won’t be able to push to GitHub, and your history will require rewriting with
git lfs migrate import. If you have a file smaller than 100 MB, you can use
git lfs migrate import --no-rewrite to create new commits that move the file to Git LFS, allowing you to repair the state of your repository more easily than ever.
If you have committed a handful of files that should have been stored with Git LFS, but aren’t, you can let Git LFS determine the affected files for you by running
git lfs migrate import --fixup. The
--fixup flag automatically reads
.gitattributes file(s) in your repository, and converts Git objects that should be stored with Git LFS automatically:
In the following example, notice how our .gitattributes file says that
*.png‘s should be tracked using Git LFS, but we added mona.png without Git LFS:
$ cat .gitattributes *.png filter=lfs diff=lfs merge=lfs -text $ git cat-file -p :mona.png | file -s /dev/stdin: PNG image data, 896 x 896, 8-bit/color RGBA, non-interlaced
We can easily fix this without having to tell Git LFS which files to start tracking:
$ git lfs migrate import --fixup migrate: Fetching remote refs: ..., done migrate: Sorting commits: ..., done migrate: Rewriting commits: 100% (2/2), done master 1002728154804338fe645976ad8b7258b0be0810 -> 076e2bfe114df5575b1130f694c18d1b26c86b86 migrate: Updating refs: ..., done migrate: checkout: ..., done $ git cat-file -p :mona.png version https://git-lfs.github.com/spec/v1 oid sha256:49afbfc61b10df78377f8f7dac774158e1a0197740e160ea3572d9839c61ac04 size 106277
Now mona.png is stored correctly using Git LFS!
Lastly, if you want to stop using Git LFS and export your large objects, you can use
git lfs migrate export. It accepts the same arguments as
git lfs migrate import, and easily allows you to take files out of Git LFS.
We have updated several of the scripts and programs used to develop and hack on Git LFS to feel more familiar to open source contributors. The test suite now outputs results using the TAP format, enabling it to be run with
prove. Similarly, the project can now be built using a
Makefile, which should feel more familiar to developers comfortable working with Git.
You’ll see a handful of other new features and bug fixes in v2.5.0 like improved support for object alternates, correct
git lfs status output from subdirectories, and more.
