Yang Date: Tue Oct 27 14:47:33 2015 -0700 Reimplement shadowing on a per database basis. Summary: This commit reimplements shadowing on package databases by doing the shadowing calculation on a per-database basis: specifically, if a later package database shadows a package from the earlier databases, we first remove that package (and its transitive dependencies) before merging the databases together. This should also fix bootstrapping GHC HEAD with HEAD. Signed-off-by: Edward Z.
