Subject: [PATCH 0/2] rebase: broken behavior with --keep-empty
Date: Fri, 20 Nov 2015 13:04:38 +0100 [thread overview]
Message-ID: <1448021080-4994-1-git-send-email-ps@pks.im> (raw)
I've recently run into broken behavior with `git-rebase` and
`--keep-empty`. As soon as `--keep-empty` is specified, we fall
back on using `git cherry-pick` instead of `git am` for rebasing
the commits, which seems to not work correctly.
In fact I guess there are two different bugs in here. The first
bug is in using `git cherry-pick --allow-empty` instead of `git
cherry-pick --keep-redundant-commits`, as judging from
git-rebase(1) we also want to keep commits that are already
included in the branch that is being rebased upon whe we use
`--keep-empty`.
The second bug is that we fail to correctly record the
rebasing-state when using cherry-pick. This causes us to end up
in cherry-picking mode as soon as the invoked cherry-pick command
runs into any error (e.g. due to a conflict or the broken
behavior with `--allow-empty`). There is also no possibility to
get back into rebase-mode from here.
I've written two tests that document these breakages, as well as
a fix to the first described breakage. I did not fix the second
breakage of not recording rebase-state, though, as this is
somewhat more involved.
