From 0b4ae1c7742cec14395a0d845e1ed42b88b0e215 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Sun, 9 Mar 2014 10:05:54 -0700 Subject: bitbake: cooker: Handle SIGTERM more gracefully If the cooker receives a SIGTERM it currently hangs using 100% CPU, This patch adds in an intercept for the event and puts the cooker into shutdown mode allowing it to exit cleanly/safely and avoiding the hang.
