No, it downloads a fresh copy of the sync database (the point is, after all, to have the latest sync database) to a temporary location. The most interesting part for this is probably +/- around line 100. It also doesn't wipe it after that. Any subsequent invocations of checkupdates will reuse that sync DB (assuming $CHECKUPDATES_DB is not changed and the system isn't rebooted in case it's on a tmpfs), to avoid unnecessary re-downloading if there are no changes on the mirror. I personally keep my $CHECKUPDATES_DB in $XDG_STATE_HOME/pacman/checkupdates, for instance. Best, Tinu
