From 75fc9a8d408640d97481d310084b212a01dc5f8b Mon Sep 17 00:00:00 2001 From: Ross Burton Date: Fri, 4 Mar 2016 16:48:37 +0000 Subject: uninative: correctly enable uninative The previous attempt at soft-failing when uninative was enabled didn't actually work, because the workers didn't evaluate the function that actually enabled uninative. In a BuildStarted handler we can check if we need to download or extract the uninative tarball. In a ConfigParsed handler on the workers we can check if the uninative loader is present, and if so enable it.
