suggestion? only pull cleanly applying commits

Hi!

I've a scenario where I don't really want to do a full merge but rather to pull all commits from another repository that merge without conflicts.

I've put together the script at the bottom which seems to work ok but is damn slow.

Is there a smarter and faster way to do this that I missed reading the documentation?

Any help would be really appreciated! :-)

Regards, Maximilian

#!/bin/sh

for commit in `git rev-list --reverse HEAD..other-repository/master`; do
        git diff-tree -p $commit|patch --dry-run -p1 -N -f >/dev/null
        if [ $? -eq 0 ]; then
                echo "getting $commit"
                parents=`git rev-list --parents -n1  $commit|wc -w`
                if [ $parents -eq 2 ]; then
                        git cherry-pick $commit
                else
                        git cherry-pick -m1 $commit
                fi
        fi
done
