I thought the same thing when I first posted that it was probably an easy change to this code (and then didn't do it myself) and again when I read Johannes' implementation. Both times I agreed with you Junio that it was probably too expensive and not worth doing. Most of the time we assume not only that the SHA1 itself is unique but also that it some hex character prefix is unique (such as 6 or 8 digits). One might be able to argue that if we have duplicate commits (when abbreviated) that you might be able to break the tie by looking at the tag but even then you may not always be able to do so. So no, probably not worth it... -- Shawn. - 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
