Past two days have been spent making [[todo/import_tree]] interoperate
safely with `git annex export`. This was more complicated and needed more
methods to be added to the remote API than I had expected.
At this point, the directory special remote's implementation is no longer
an unsafe prototype, but detects conflicting file modifications and
avoids overwriting them when exporting to the directory.
Here it is in action:
joey@darkstar:/tmp/testrepo> git annex unlock foo
joey@darkstar:/tmp/testrepo> echo version from git > foo
joey@darkstar:/tmp/testrepo> echo version from special remote > ../dir/foo
joey@darkstar:/tmp/testrepo> git annex add foo
joey@darkstar:/tmp/testrepo> git commit -m add
joey@darkstar:/tmp/testrepo> git annex export master --to dir
unexport dir foo failed
export dir foo failed
(recording state in git...)
git-annex: export: 2 failed
joey@darkstar:/tmp/testrepo> git annex import master --from dir
import dir ok
update refs/remotes/dir/master ok
(recording state in git...)
joey@darkstar:/tmp/testrepo> git merge dir/master
Auto-merging foo
CONFLICT (content): Merge conflict in foo
Automatic merge failed; fix conflicts and then commit the result.
joey@darkstar:/tmp/testrepo> echo merged version > foo
joey@darkstar:/tmp/testrepo> git annex add foo
joey@darkstar:/tmp/testrepo> git commit -m resolved
joey@darkstar:/tmp/testrepo> git annex export master --to dir
unexport dir foo ok
export dir foo ok
(recording state in git...)
The feature is close to being mergeable to master now, but still needs some
work on the progress display of `git annex import`, and on supporting
imports from the same special remote to different git repos.
