I have two sets of files.
A_Old is a large unversioned directory tree containing many files.
A_Updated is a git repository containing the files from A_Old, some of
which have been modified. A_Updated also contains new files.
I am looking for a way of cloning only the new or modified files from
A_Updated to A_Old. I would like A_Old to become a clone of A_Updated,
however I don't want to download the entire archive because of access
speed issues.
Timestamps on all files are accurate.
1. Create a commit from the files in each of the directories.
2. Use git rev-list --objects --all | sort to generate a sorted list of
objects in each of the repositories.
3. In A_Old, generate a pack from the objects that are not in A_Updated
using 'comm' of the objects lists piped into git pack-objects.
4. Transfer this pack from A_old to A_Updated.
5. Use git fast-export --no-data in A_old.
6. Use git fast-import in A_Updated to import the commit that you have
in A_Old into A_Updated.
7. In A_Updated, git reset --soft the-commit-from-A_Old && git commit.
Now you have a second commit with the updated state.
8. Use git-remote to connect the two repositories and to push or pull
the updated state.
