It works ok in a local git repository. `git add` lets +git-annex decide if it wants to annex a file's content, and checking out +branches and other git commands involving those files works pretty well. + +It can sometimes be slow; git's smudge interface necessarily needs to +copy the content of files around, particularly when checking out files, +and so it's never going to be as fast as the good old git-annex symlink +approach. Most of the slow parts are things that can't be done in direct +mode repos though, like switching branches, so that isn't a regression. + +No git-annex commands to manage the annexed content work yet. That +will need a key to worktree file mapping to be maintained, and implementing +that mapping and ensuring its always consistent is probably going to be +the harder part of this. + +Also there's the question of how to handle upgrades from direct mode +repositories. This will be an upgrade from annex.version 5 to 6, and you +won't want to do it until all computers that have clones of a repository +have upgraded to git-annex 6.x, since older versions won't be able to work +with the upgraded repository. So, the repository upgrade will need to be +run manually initially, and it seems I'll need to keep supporting direct +mode for v5 repos in a transition period, which will probably be measured +in years. |
