Jenkins child jobs not stopped by interrupt signal

Carry on the discussion from #20395 (comment)

@JasonFengJ9 commented:
So Click here to forcibly terminate running steps doesn't abort the child jobs.
Do we have to log in to the machine manually to kill the processes?

It depends what the child job is doing. It's a known issue with setting ITERATIONS that an interrupt signal only stops the current iteration and the job continues with the next iteration.

When you interrupt the first time it signals all the child jobs and the parent waits for them to finish. By using Click here to forcibly terminate running steps it may send another interrupt to the child jobs and then it forcibly kills the parent so it's not waiting for them to finish any more.

Okay, what's the reliable way to ensure all child jobs are aborted, or is there such a link instead of logging in to the machine manually?

[pshipton]

The only way I know to kill the child jobs is to keep stopping the parent job until all the child iterations are finished. Or open the child jobs individually and do the same. If each child isn't running the same iteration, continuous stopping may interrupt the cleanup steps at the end of job.

It's been a known behavior for some time, not sure if @llxia has any plans to change it.

I think we can try to check currentBuild.result inside the loop. If it is ABORTED, then break.

@annaibm can you try to add the check inside for https://github.com/adoptium/aqa-tests/blob/2c47e24c512b6419c8b2a01b75ae2d10c4dd9215/buildenv/jenkins/JenkinsfileBase#L766-L787?

• In a simple case, child jobs can be stopped without the problem. The issue occurs when running complicated tests (i.e., MiniMix_3h_0).

• currentBuild.result may not contain the correct info. We had to set the build result based on the exception https://github.com/adoptium/aqa-tests/blob/master/buildenv/jenkins/openjdk_tests#L490-L497
