I was trying this: git-filter-branch -- --since=2007.01.10 \ refs/heads/topic refs/heads/master where topic's last change is from before 2007.01.10, i.e. it is not among the rewritten commits. And I get this: WARNING: Ref 'refs/heads/master' is unchanged WARNING: 'refs/heads/topic' was rewritten into multiple commits: 329325526647503382ae7dee41c12fe6b81bbe43 2bdf3349b76f72ceb71755c75a555d60bc7c73aa ce6c9dfeac5ddbd64da2d9360d6552717df81d1f The first 2 of these 3 sha1s happen to be merge bases of topic and master, but none of them appear anywhere in git rev-list --parents --boundary --since=2007.07.10 \ refs/heads/topic refs/heads/master What's up? -- Hannes - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
