What about having one notes ref per branch? If/when the branch is merged, the associated notes ref containing the annotations for the commits on that branch would be merged as well (using "git notes merge"). Sure, using one notes ref per branch is more expensive than a single notes ref, but it's still cheaper than one ref per signed commit (which is what we get when using annotated tags). And it prevents the added code and complexity of the timestamped mapping approach. ...Johan -- Johan Herland, <johan@xxxxxxxxxxx> www.herland.net -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
