Re: [PATCH] rebase: apply and cleanup autostash when rebase fails to start

Phillip Wood [off-list ref] writes:

Applying the stash should not fail because the rebase has not started
and so HEAD, the index and the worktree are unchanged since the stash
was created. If it does fail for some reason then apply_autostash()
creates a new entry under refs/stash. We definitely do want to remove
the directory otherwise we're left with the inconsistent state we're
tying to fix.

If it is not expected to fail 99% of times, it feels more prudent to
abort loudly without making further damage to lose information and
ask the user to check what happened in the working tree, rather than
blindly removing the clue to understand what went wrong.  For
example, could the reason why applying the stash failed be because
the user forgot that the working tree was being used for rebasing
and mucked with its contents from say another terminal?

Thanks.
