'grit' = 'git' but new and unpolished.
TL;DR
-
A writable FUSE filesystem that stores data in Git
-
A command 'grit' that lets you do version control in a Grit tree
-
Grit supports submodules natively
-
Grit lazily fetches blob contents using git protocol v2
-
Grit does not expose the .git directory, ensuring that users cannot break abstraction boundaries
-
Grit needs go-fuse; probably doesn't work on OSX
BACKGROUND
This is an exploration of how the JJ workflow/data model could work with Git projects that are large and use submodules. It lacks functionality for practical use. See TODO file for missing bits.
DESIGN
-
All of the logic is inside the FUSE daemon; the command-line client RPCs to the FUSE daemon
-
The git repo serves as storage
-
Each workspace is stored in a refs/grit/$WORKSPACE-NAME ref
