Indeed, subversion first uploads the stuff, only then creates a new revision. In any case one does not want multiple commits at the same time in any case. For full portage the problems are more likely to be with svn update. One can expect there will be a lot more updates than commits. As the commits done are fairly small, those should not be an issue. Updates work on the whole tree however. Initial checkouts are worse, because they require the head to be reassembled (IIRC). Head checkout could be cached though (but I don't think that's done currently). Paul -- Paul de Vrieze Gentoo Developer Mail: [EMAIL PROTECTED] Homepage: http://www.devrieze.net
