Revert one patch of git rebase

1.5k views Asked by At

I'm in the middle of one big rebase with a lot of conflict.

just found out a couple of git rebase --continue before actual I accidentally delete one file instead of another.

How can I go back in pacth and fix this, and then reapply the patch?

Edit: --abort is not a solution as I will have to do ALL the patch again. I want to abort only part of them

Everything in your repo stays there until git sees it's been wholly unreachable, through any ref, for at least a month1.

So you've done some equivalent of git rebase master topic, with say 26 commits A-Z on topic since the branch, and you did what turns out to be a really bad oops rebasing O and didn't really get the full effect until S:

     A...O...Z        topic
    /
...b....*             master
         \
          A2..O2..S2  the inflight rebase with the mistake in the rebased O, O2

Your backout is

git tag restart O2~
git rebase --abort
git rebase --onto restart O^ topic

and now you only have to redo the commits infected by the oops.

If there are good parts to the commits in the O2~..S2 series, conflict resolutions you want to retrieve, you can tag S2 as well, and then during your redo just check out the good parts from those commits, git checkout -p boneyard~3 -- goodpart1 goodpart2 etc etc (where you've tagged S2 as "boneyard" and the good parts are in P2)

I've done this, hosed a rebase and had to redo it. I wouldn't be surprised if everyone's done that at one point or another. It's no big deal, even for seemingly horrendous cases like yours.

git rebase --abort and redo the rebase.

Do the following:

git rebase --abort

This will abort the rebase and bring your HEAD back to the state it was before the rebase.

I don't think there is an option to revert a single patch using git rebase. See the possible options in git rebase docs.

git rebase --help
GIT-REBASE(1)                     Git Manual                     GIT-REBASE(1)

NAME
       git-rebase - Forward-port local commits to the updated upstream head

SYNOPSIS
       git rebase [-i | --interactive] [options] [--onto <newbase>]
               [<upstream>] [<branch>]
       git rebase [-i | --interactive] [options] --onto <newbase>
               --root [<branch>]
       git rebase --continue | --skip | --abort

   In case of conflict, git rebase will stop at the first problematic
   commit and leave conflict markers in the tree. You can use git diff to
   locate the markers (<<<<<<) and make edits to resolve the conflict. For
   each file you edit, you need to tell git that the conflict has been
   resolved, typically this would be done with

       git add <filename>

   After resolving the conflict manually and updating the index with the
   desired resolution, you can continue the rebasing process with

       git rebase --continue

   Alternatively, you can undo the git rebase with

       git rebase --abort
