[pacman-dev] Adding an expiry time to repo databases

Hi all, I have made a start at adding an expiry time to repo databases. See the three patches here: https://patchwork.archlinux.org/bundle/Allan/repo_timestamp/ My question is, what should we do once a database is determined to be expired? Follow the example of a bad signature, and refuse to load it at all? Just refuse to install anything from it, but still enable searching etc? Just deciding "bad repo, don't use" will be much easier to implement... Comments? A
