I am developing a tool to use custom-transfer agent for git-lfs. Basically, it lets git-lfs handle all of the odd edge cases and just pushes/pulls from an rclone remote.
For me, this solves one of my fundamental problems with git-lfs: you need a custom server! Instead, you can now use any rclone remote!
(It is still centralized unlike git-annex, which can work with rclone, but that latter is super complex and overkill for most).
I am pretty well versed in git, rclone, and python, but not so much git-lfs. I have been using it for the past few weeks without issue but it needs more testing (formal and production).
I also have no way to test on Windows. I suspect there will need to be some modifications to the subprocess calls but I just don't know.
The readme has a lot of details on what remains.
Please check it out, test it, let me know of issues and ideas, and/or submit a pull request!
