Out of curiosity, is that actually measurably more efficient? Since we stop traversing a commit's parents when we see it does not have any of the flags we are clearing, we should visit most commits once. The exception is ones that we hit by multiple paths. But that should be the same whether it is done as part of a single traversal or multiple; in each case, we hit the commit and say "Oh, already cleared; do not add it to the parents list". So I would expect it to have little to no impact on performance. I still think it is a sane interface change; I was just curious from the commit message whether there could be a performance impact. -Peff -- 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
