I'm observing that when certain pod failures occur I see the build transition to failed status with an empty logSnippet, and then a fraction of a second later the logSnippet is set. This makes trying to programmatically capture build logSnippet painful because i have to wait an arbitrary amount of time after seeing failed for a logSnippet that may or may not get set. The logSnippet is useful to my client (ci-operator) so that I can convey that back to the user for summarizing why we're failing a build. Is this something in the build controller, or something in the pod? Expected outcome: phase set to Failed at the same time logSnippet is set. Actual outcome: phase set to failed, and then a subsequent update sets logSnippet. Impact: Makes it hard to have a good UI for a developer of openshift using our CI tools for when a build fails.
I *think* it's because setBuildCompletionData checks: if build.Status.Phase == buildapi.BuildPhaseFailed && len(build.Status.LogSnippet) == 0 && but should instead check the current and new phase if build.Status.Phase == buildapi.BuildPhaseFailed || update.getPhase() == buildapi.BuildPhaseFailed && len(build.Status.LogSnippet) == 0 && ...

Yes that looks fine, thanks!
