Thanks for pointing it out :) I'll try this stuff out and report back once I have my portage tmpfs created again. > "git commit <dir>" and "git status <dir>" still do full tree lstat(). > I can try to make a patch or two to reduce lstat() in such cases. > That would definitely compliment the --stat option to git diff et al, making git more usable on repos with a huge no. of files. Now that I think about it, why does git <command> <dir> need to do a full tree stat at all? Doesn't the added specification of <dir> mean "I'm only interested in this dir for this command, other stuff doesn't matter"? > Does that help? Quite helpful indeed; now if only someone would implement recursive timestamps for directories... ;) -- ~Nirbheek Chauhan Gentoo GNOME+Mozilla Team
