Description Martin Väth 2022-08-18 05:28:35 UTC 
portage-3.0.34: When calling emerge --metadata, it needs less than a second and only generates empty directories under /var/cache/edb/dep.

Similarly, if /etc/portage/modules contains the lines

portdbapi.auxdbmodule = cache.sqlite.database
eclass_cache.dbmodule = cache.sqlite.database

apparently only empty (size 16384) sqlite files are created in that directory.

I did not investigate with which portage version the behavior changed.

Note that some cache methods of eix are intended to use that data, so currently for users of e.g. cache method sqlite eix is broken, see e.g.
