Or at least it's what I intended. Oh, of course. "--full-history" is about showing any pointless change, "the mainline was a lot more up-to-date and there were changes relative to a fork based on an older baseline", so your updated "log" should show that in the mainline git-cvsserver.perl has been more fresh when that merge happened. But it shouldn't appear if the user does not ask for "--full-history". > However, your particular example occurs *without*--full-history, which > suggests a problem. Yes. > I note that "gitk v1.8.3^0..v1.8.4" and "git log --parents > v1.8.3..v1.8.4" show that merge in Git 1.8.3, but not in Git 1.8.4. So > we're going partially forwards, at least. With the testcases demonstrating the cases your series fixed that all look sensible, I think it is not really an option for us to revert them; you do not have to defend it with "we are going partially forwards" ;-). -- 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
