Unlocked files with content not present appear as regular files containing
|
|
an annex pointer. This is not ideal as the user has no way to know if the
|
|
content is present other than file size. Broken symlinks are a better
|
|
representation.
|
|
|
|
# smudge approach
|
|
|
|
It would be possible to make `git annex smudge --update` write symlinks
|
|
for the missing content files. But then git will think they're modified,
|
|
and committing will lock them.
|
|
|
|
Is it possible at all for the index to be in the state where a file that's
|
|
been converted to a symlink is not treated as modified? The index contains
|
|
an object type value, which will need to be set to symlink. But if
|
|
the tree for the checked out branch has the object type of regular file,
|
|
git diff-index would consider there to be a staged change. So probably
|
|
it's not possible. Still, it would be worth playing with the file format to
|
|
see if perhaps it can be tricked.
|
|
|
|
Or such staged (non-)changes could be filtered out by the pre-commit hook.
|
|
This is probably possible, but git status, diff, etc would show the
|
|
non-present files as modified still.
|
|
|
|
# adjusted branch approach
|
|
|
|
Use an adjusted branch, where files with missing content are locked.
|
|
|
|
Often the users who are affected by this are already using git-annex adjust
|
|
--unlock, so using a different adjustment would be a minor change for them.
|
|
|
|
Such a branch is very conceptually similar to a --hide-missing branch.
|
|
And so certianly seems doable. Like a --hide-missing branch, there's an
|
|
open question of how to update the branch after get/drop of content.
|
|
|
|
Needing to manually re-run git-annex adjust, as is done with --hide-missing,
|
|
means the user is still going to get surprised when files they open
|
|
turn out to have missing content. So for this to really be useful,
|
|
the branch needs to automatically get updated.
