Some users would like +to drop any objects that are not pointed to by any commit, but keep any +object that any commit ever referenced. + +This could be a switch, like --ever. + +The implementation would need to walk the history of all branches and check +all commits. This would tend to be slow. It could look at tags+branches as +it does now as a first pass, and only do the slow part if there are objects +not referred to by the tags+branches. And, it could stop looking through +the whole commit history if there were no more objects to check. Still, +gonna be slooow. Another optimisation would be to get only the objects +changed by the commit, and not look at the whole tree as it appeared on +each commit. --[[Joey]] |
