Colocation is about sharing the working copy between jj and git. It's
less important where the repo is stored. I therefore think we should
not call it "colocated repo". I considered renaming it to "colocated
working copy" but that sounded awkward in many places because we often
talk about the whole workspace (repo + working copy), so "In colocated
workspaces with a very large number of branches or other refs" sounds
better than "In colocated working copies with a very large number of
branches or other refs".
Once we support colocate workspaces in non-main Git worktrees, I think
this rename will be even more relevant because then all those
workspaces share the same repo but only some of them may be colocated.
This doc describes what we need to consider in a submodule storage
solution, some possible solutions and what criteria we should use to
decide on a future direction.
This is still a WIP:
- The solutions are still underdescribed
- The actual evaluation of solutions is missing
Suggestions for the above are welcome :)
This document is meant to be a record of how we think about Git
submodules (and not a _current_ implementation of submodules). We will
fill it out incrementally as we get a clearer idea of what we want
submodules to look like.
As an initial version, I started with (IMO) the least controversial
points:
- We want to support most workflows Git submodules users are accustomed
to.
- A roadmap that allows us to incrementally roll out Git submodule
functionality (instead of having to boil the ocean).
