![Ramkumar Ramachandra](/assets/img/avatar_default.png)
In the same spirit as ".git/sequencer/head" and ".git/sequencer/todo", introduce ".git/sequencer/opts" to persist the replay_opts structure for continuing after a conflict resolution. Use the gitconfig format for this file so that it looks like: [options] signoff = true record-origin = true mainline = 1 strategy = recursive strategy-option = patience strategy-option = ours Helped-by: Jonathan Nieder <jrnieder@gmail.com> Helped-by: Christian Couder <chriscool@tuxfamily.org> Signed-off-by: Ramkumar Ramachandra <artagnon@gmail.com> Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
