From 88c8dcf94945937bea94b330067fe68fe24665b2 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 5 Feb 2015 22:06:13 -0700 Subject: [PATCH] buildman: Adjust the 'aborted' heuristic for writing output At present buildman tries to detect an aborted build and doesn't record a result in that case. This is to make sure that an abort (e.g. with Ctrl-C) does not mark the build as done. Without this option, buildman would never retry the build unless -f/-F are provided. The effect is that aborting the build creates 'fake errors' on whatever builds buildman happens to be working on at the time. Unfortunately the current test is not reliable and this detection can trigger if a required toolchain tool is missing. In this case the toolchain problem is never reported. Adjust the logic to continue processing the build result, mark the build as done (and failed), but with a return code which indicates that it should be retried. The correct fix is to fully and correctly detect an aborted build, quit buildman immediately and not write any partial build results in this case. Unfortunately this is currently beyond my powers and is left as an exercise for the reader (and patches are welcome).
