Rewrite a merge commit into a squash merge commit
git-squash merge commit
git merge --squash
squash all commits on a branch
squash commit into merge commit
git squash old commits
git squash commits after push
git rebase squash
I made a merge of a long lived branch and it took me time to complete the merge because of the conflicts resolution.
I found out that I cannot publish my work with
git svn rebase will rebase all the commits of the merged branch instead of submitting one single merge commit. I discovered
git merge --squash a bit too late...
Is it possible to change (rebase interractive ?) the merge commit into a "squash merge" commit without loosing all the conflicts resolution work already done (i.e. without triggering a new merge as I had not enabled the
rerere tool) ?
