feat: git LFS support #121

open opened by ralith.com

Git LFS is popular, but forge support sucks:

  • GitHub hosting is unreasonably expensive
  • Self-hosting breaks forge-based access control

Tangled is in a unique position to do better here by starting off with an open identity infrastructure and first-class self-hosting. A good implementation would include deduplication (e.g. FastCDC) and allow users without write access to submit PRs containing LFS-managed data, even to self-hosted repos, without introducing new abuse risks.

This might be moot if git gets better native support for binary files, but that seems unlikely to happen any time soon.

@anil.recoil.org‬ had a look at this already and noted some challenges: https://bsky.app/profile/anil.recoil.org/post/3ll5fituyr22f

The issue with current git-lfs is that it's implemented client side, and so there would need to be an HTTP-level proxy at the PDS to handle the uploads.

There's also an emerging new server-side LFS being merged into git this year in the form of "large object promisers" that would be more transparent to the client; more details at https://tylercipriani.com/blog/2025/08/15/git-lfs/#the-future-git-large-object-promisors
