I've got two branches from my master:
Is there a way to copy yesterday's commits from wss to v2.1?
You can do this with multiple commits too, just cherry pick several, then reset back to the last commit you want to keep. The process is the same if you have committed to local master by mistake - just cherry-pick to a branch, then reset master. Only ever do this if you haven't pushed the commits to origin.
Use
git cherry-pick <commit>
to apply <commit>
to your current branch.
I myself would probably cross-check the commits I pick in gitk
and cherry-pick them with right-clicks on the commit entry there instead.
If you want to go more automatic (with all its dangers) and assuming all commits since yesterday happened on wss you could generate the list of commits using git log
(with --pretty
suggested by Jefromi)
git log --reverse --since=yesterday --pretty=%H
so everything together assuming you use bash
for commit in $(git log --reverse --since=yesterday --pretty=%H); do git cherry-pick $commit done
If something goes wrong here (there is a lot of potential) you are in trouble since this works on the live checkout, so either do manual cherry-picks or use rebase like suggested by Jefromi.
You should really have a workflow that lets you do this all by merging:
- x - x - x (v2) - x - x - x (v2.1) \ x - x - x (wss)
So all you have to do is git checkout v2.1
and git merge wss
. If for some reason you really can't do this, and you can't use git rebase to move your wss branch to the right place, the command to grab a single commit from somewhere and apply it elsewhere is git cherry-pick. Just check out the branch you want to apply it on, and run git cherry-pick <SHA of commit to cherry-pick>
.
Some of the ways rebase might save you:
If your history looks like this:
- x - x - x (v2) - x - x - x (v2.1) \ x - x - x (v2-only) - x - x - x (wss)
You could use git rebase --onto v2 v2-only wss
to move wss directly onto v2:
- x - x - x (v2) - x - x - x (v2.1) |\ | x - x - x (v2-only) \ x - x - x (wss)
Then you can merge! If you really, really, really can't get to the point where you can merge, you can still use rebase to effectively do several cherry-picks at once:
# wss-starting-point is the SHA1/branch immediately before the first commit to rebase git branch wss-to-rebase wss git rebase --onto v2.1 wss-starting-point wss-to-rebase git checkout v2.1 git merge wss-to-rebase
Note: the reason that it takes some extra work in order to do this is that it's creating duplicate commits in your repository. This isn't really a good thing - the whole point of easy branching and merging is to be able to do everything by making commit(s) one place and merging them into wherever they're needed. Duplicate commits mean an intent never to merge those two branches (if you decide you want to later, you'll get conflicts).
