From db3b86e7f34f4c3ccb42e98465f2069aa642a85f Mon Sep 17 00:00:00 2001 From: Dan McGee Date: Tue, 7 Jun 2011 17:29:55 -0500 Subject: Do database signature checking at load time This is the ideal place to do it as all clients should be checking the return value and ensuring there are no errors. This is similar to pkg_load(). We also add an additional step of validation after we download a new database; a subsequent '-y' operation can potentially invalidate the original check at registration time. Note that this implementation is still a bit naive; if a signature is invalid it is currently impossible to refresh and re-download the file without manually deleting it first. Similarly, if one downloads a database and the check fails, the database object is still there and can be used. These shortcomings will be addressed in a future commit.

This is groundwork for letting pactree walk the sync DBs.
