Title: Message Title

Michael Mrozek created an issue   Jenkins / JENKINS-60702 Two calls to the build function can trigger the same run Issue Type: Bug Assignee: Unassigned Components: pipeline-build-step-plugin Created: 2020-01-08 22:14 Environment: Jenkins 2.211 Pipeline: API 2.38 Pipeline: Build Step 2.11 Priority: Minor Reporter: Michael Mrozek I'm not certain which component is responsible for this, so I went with the Pipeline Build Step plugin. When using build to trigger another job, there seems to be a race condition where two calls to the function at approximately the same time with the same target job can both "start" the exact same run. For example, this code (the target job is irrelevant, I just happened to have an empty Freestyle job hanging around to test with): parallel ( First : { build job: "Test/Freestyle", wait: true }, Second: { build job: "Test/Freestyle", wait: true }, ) causes the following: Branch event Obtained Jenkinsfile from 9c8963507d90d9cc4c8acb030efa07ca8a7d8d25 Running in Durability level: MAX_SURVIVABILITY [Pipeline] Start of Pipeline [Pipeline] parallel [Pipeline] { (Branch: First) [Pipeline] { (Branch: Second) [Pipeline] build Scheduling project: Test » Freestyle [Pipeline] build Scheduling project: Test » Freestyle Starting building: Test » Freestyle #1 Starting building: Test » Freestyle #1 [Pipeline] } [Pipeline] } [Pipeline] // parallel [Pipeline] End of Pipeline Finished: SUCCESS Notice that instead of starting Test/Freestyle twice, both branches claim to have started run #1. Adding a sleep in one of the parallel branches fixes it, but I think this can happen any time two jobs happen to try and fork the same target job at the same time. This might be the same as JENKINS-55210; I can't tell for sure.
