I'm trying to take a branch with changes and bring it back to be identical to the upstream it diverged from. The changes are both local and have been pushed to github, so neither git reset or git rebase are really viable, since they change history, which is a bad thing with a branch that's already been pushed.
I've also tried git merge with various strategies but none of them undo the local changes, i.e. if I'd added a file, a merge might bring other files back in line, but I'll still have that file that the upstream doesn't have.
I could just create a new branch off the upstream, but i'd really like a merge that in terms of revision history applies all the changes to take my branch and make it identical to the upstream again, so that I can safely push that change without clobbering history. Is there such a command or series of commands?
