From 6e3eefb997063971801bea933f319bb428b33fa5 Mon Sep 17 00:00:00 2001 From: Elliot Smith Date: Fri, 18 Dec 2015 11:55:25 +0200 Subject: bitbake: toaster: Rework mimetype guessing to fix artifact downloads Artifact download links were broken because the function to get the mimetype for the artifact was incorrectly using the underlying mimetype library. The function was also attached to the build environment controller, which was unnecessary, as we only support local controllers anyway. Remove the mimetype getter on the build environment and use the one in the view code instead. This prevents the download error from occurring.
