Good job @waveywaves ! 😸

My comments are nice to haves, its all implemented and tested well.

I think this PR would benefit from a documentation entry in "Specifying taskRunSpecs". You could reuse the explanation from #7752.

Let me know if I can support.

I think this check would fit very well into validateTaskRunSpec() in line 338 after the trs.PodTeplate check. Then you would not need the loop and the call to validateTaskRunSpec in line 95 here.

I think you can also reuse validateTimeoutDuration and remove the if statement.

You could add another valid test covering the case when the pipelineTimeout.Duration == config.NoTimeoutDuration, then there should be no error when task timeout exceeds pipeline timeout.

I believe this should be comparing ps.Timeouts.Tasks, and if that is not specified then falling back to ps.Timeouts.Pipeline. Since ps.Timeouts.Tasks is already enforced to be less than or equal to ps.Timeouts.Pipeline

What do you think about something like this? This implementation adds a couple things:

  1. Creates a central timeout validation function which falls back to the default if no timeout is supplied, and if the timeout is negative then it of course fails. It DRYs up the validation for both TaskRuns schema versions and could also be used on the PipelineRun.spec.timeouts as well
  2. PipelineRunTask timeout check now ensures that the timeout is 0 < timeout < maxTimeout where maxTimeout is the first present in: pr.spec.timeouts.tasks || pr.spec.timeouts.pipeline || defaultTimeout,
