Here are commands that slightly simplify / automate things, which I used to bisect: rm -rf repo git init repo cd repo git commit --allow-empty -qm base touch file git add . GIT_AUTHOR_DATE='@123456789 +0000' git commit -qm "this message says pick" GIT_EDITOR='sed -i s/pick/reword/' \ git.compile rebase -i --committer-date-is-author-date HEAD^ # not strictly necessary, but when it works, you can see that the # timestamps correctly match, and that "pick" was changed to "reword" # in the message. Of course when it doesn't work, rebase aborts, so # that's easier to see than looking at the commit. :) git cat-file commit HEAD > What happened instead?

It looks like things did work back in 7573cec52c (rebase -i: support --committer-date-is-author-date, 2020-08-17). Bisecting shows that it broke in baf8ec8d3a (rebase -r: don't write .git/MERGE_MSG when fast-forwarding, 2021-08-20). +cc Phillip (who wrote both commits). -Peff
