Junio, we should consider a v2.0.4 with that series, I think. This is a
pretty serious regression in diff-tree (I didn't even realize that the
buffer-slab work went into the maint series; that may have been a little
ambitious).
Or v2.0.4 without that series, which is how we usually do things,
but let me see if jk/alloc-commit-id is easily applicable there
first.
Yeah, I'm fine with a straight revert, too (I think it is fine to keep
in master, though). I think jk/alloc-commit-id is built right on top of
the original commit-slab topic, so it should be easy to do either way.

Thanks for dealing with it.
Whatever we do, perhaps it is worth applying the test below on top?
Yeah, thanks.  I think that is a good idea.  I was preparing a patch
to tuck your minimum reproduction at the end of 4202, but your version
and placement makes good sense.

Subject: t4013: test diff-tree's --stdin commit formatting

Once upon a time, git-log was just "rev-list | diff-tree",
and we did not bother to test it separately. These days git-log
is implemented internally, but we want to make sure that the
rev-list to diff-tree pipeline continues to function. Let's
add a basic sanity test.
