Bug Report: "git reset --hard" does not cancel an on-going rebase

["Thomas Bétous" <th.betous@gmail.com>]

Hello,

I would like to report an inconsistent behavior of the rebase/reset commands. I don’t know whether it is an actual bug or something else but according to me something is not right.
When a rebase gets paused (because of a conflict for instance) I would expect the command "git reset --hard" to cancel this on-going rebase but it does not.
I expect this because for instance "git reset --hard" cancels a cherry-pick in the same use case so I think the behavior of these 2 commands should be consistent.

The issue can be reproduced with the following commands:
# First trigger a rebase that will paused because of a conflict
# (there is probably a simpler way to end up in this use case)
$ git init test-repo-rebase-reset
$ cd test-repo-rebase-reset/
$ touch file
$ git add file
$ git commit file -m 'First commit’
$ echo "dummy line" > file
$ git commit --all -m 'Second commit’
$ git switch --create new-branch HEAD~1
$ git rm file
$ git commit -m 'Remove file’
$ git rebase master
# Let’s check that the rebase got paused because of the conflict
$ git status
$ git reset --hard
# Even after the “git reset --hard“ the rebase was not aborted
$ git status
# Now let’s check what happens with the cherry-pick command
$ git rebase --abort
$ git switch master
$ git cherry-pick $(git rev-parse -1 new-branch)
# The cherry-pick got paused because of the same conflict
git status
# Let’s try to abort the cherry-pick with the reset command
git reset --hard
# Double check the cherry-pick was aborted
git status

I think the behavior will be the same on all OS but if it helps I was able to reproduce it on Cygwin/Windows 10 with git 2.28.0 and Mac OS with git 2.26.0

Note that in the commands above I didn’t give any revision to the reset command but the issue would be the same if I did. Moreover it makes it even more confusing I think: you can move your HEAD to any revision while the rebase is still waiting to be completed.

What do you think? Does this behavior seems normal to you?

Thank you in advance for your answer.

Best regards,

Thomas
