The stash fails to stash all the changes because of some line ending issue I've yet to understand but the stash command exit code is zero as if it had succeeded in stashing everything so the rebase creates .git/rebase-merge/autostash and continues > error: Please commit or stash them. only for the clean worktree check to fail. The cleanup path from that point assumes we have not yet created .git/rebase-merge which is not true if an autostash has been created. This means we do not pop the stash. > error: could not read '.git/rebase-merge/head-name': No such file or > directory When we try to abort we try to read some state that does not exist because the rebase never really started > and > > $ ls -la .git/rebase-merge/ > total 5 > drwxr-xr-x 1 thomas 197121 0 Jun 3 17:57 ./ > drwxr-xr-x 1 thomas 197121 0 Jun 3 17:57 ../ > -rw-r--r-- 1 thomas 197121 41 Jun 3 17:57 autostash > > I'm running on Windows, both 2.27.0.windows.1 and 2.26.2.windows.1 show > the problem.

Yes. I'm not sure what to do for the best. A simple fix to the stash failure is to check for a clean worktree after we've stashed and apply the stash and exit if the worktree is not clean. Ideally `git stash` would be able to tell us that it didn't stash everything, but that warning comes from `void check_global_conv_flags_eol()` in convert.c so it does not pass along that information to the caller. We should also improve the cleanup code path so that it applies the autostash (and removes the state dir) if it exists as after a quick glance through the code it seems we might not be applying the autostash if `git checkout`.
