From 62d598cc5aa01d23f1e9284e9e926bd55b1d1878 Mon Sep 17 00:00:00 2001 From: Ed Bartosh Date: Fri, 16 Sep 2016 17:22:31 +0100 Subject: [PATCH] runbuilds: process builds on SIGUSR1 Run main processing function 'runbuild' only if SIGUSR1 is received. This signal is sent by Toaster when build status is changed (either started, cancelled or finished). This should stop continuous database polling as run_builds function will be called only when needed, i.e. after build status is changed.
