Description:
|
This is a problem in case downstream build refers to the build of a parent project by permalink such as {{LAST_SUCCESSFUL}} and expect it will match the exact build that triggered the downstream build. This is a reasonable expectation if downstream build is triggered for stable/successful builds only.
I observed several downstream builds copied different versions of artifacts from upstream project. Due to a heavily contended queue it took ~2 minutes to schedule all downstream builds using {{hudson.tasks.BuildTrigger}}. And as the actual scheduling is done before upstream completes, several downstream builds was scheduled fast enough to observe old permalink value.
The scheduling should take place *after* upstream build is done.
EDIT: Nothing special needs to happen actually. This is what upstream is doing at the time single downstream runs in unittest without any artificial slowdowns.
