Code review comment for lp:~jamesh/thumbnailer/landing-20150622

Hi Victor, thanks heaps for helping to test this!

If you want to see what's going on with the cache, you can run a tail -f on ~/.cache/upstart/dbus.log. All the thumbnailer messages end up in there. If you want to test with an empty cache, you can run

thumbnailer-admin clear

This completely wipes the cached thumbnails. You can pull out to lots of statistics for the three internal caches with

thumbnailer-admin stats -v
