I tried to compare --force-rebase VS --no-ff for the following repository: http://jmp.sh/E7TRjcL
There's no difference in the resulf of: git rebase --force-rebase 54a4 git rebase --no-ff 54a4 (rebases all 3 commits of feature) Also, there's no difference in interactive mode: git rebase --force-rebase -i 54a4 git rebase --no-ff -i 54a4 (picks all 3 commits of feature) Is there a case where --no-ff differs from --force-rebase? --- Best Regards, Ilya Kantor On Wed, May 9, 2018 at 10:27 PM, Marc Branchaud <[email protected]> wrote: > On 2018-05-09 02:21 PM, Stefan Beller wrote: >> >> +cc Marc and Johannes who know more about rebase. >> >> On Wed, May 9, 2018 at 9:01 AM, Ilya Kantor <[email protected]> wrote: >>> >>> Right now in "git help rebase" for --no-ff: >>> "Without --interactive, this is a synonym for --force-rebase." >>> >>> But *with* --interactive, is there any difference? >> >> >> I found >> >> https://code.googlesource.com/git/+/b499549401cb2b1f6c30d09681380fd519938eb0 >> from 2010-03-24 > > > In the original discussion around this option [1], at one point I proposed > teaching rebase--interactive to respect --force-rebase instead of adding a > new option [2].
