I don't think I have any history. I use sync-depth=1 and clone-depth=1. Both git log and git whatchanged only show one commit. > Of course that history can come in handy if you need to revert > something/etc. Perhaps I should keep a few levels of history... > If you sync infrequently - say once a month or less frequently, then > I'd expect rsync to be faster. I generally sync several times a week, and git is often very much faster than rsync. Git is always done in a few seconds. The time required for rsync varies widely from a handfull of seconds to tens of minutes. > This is because git has to fetch every single set of changes since > the last sync, while rsync just compares everything at a file level. > [...] > That can add up if it has been a long time. AFAICT, the emerge repo git "depth" settings of 1 prevent that: the intermediate versions are discarded on the server side as is previous local history. The end result is similar to rsync: you fetch only the current version of what's changed since the last "sync", and there's no local history. > Bottom line is that I think git just makes more sense these days for > the typical gentoo user, who is far more likely to be interested in > things like changelogs and commit histories than users of other > distros.

Right now with a depth of 1, git log/whatchanged don't provide any information (they think all files were new as of the last "sync"). What I should figure out is what settings will preserver a few levels of changes that have been made to my local repo, without preserving intermediate changes to the master repo that never got used locally. IOW, I want all the changes made during a single "sync" to go into my local repo as a single commit regardless of how many commits have been made to the master repo since my previous "sync". I think git can do that -- whether the emerge sync settings in /etc/portage/repos.conf/gentoo.conf allow me to tell emerge to tell git to do that is the question. -- Grant
