There are a couple of other TaskRun-related functions in pipelinerun.go that might need equivalents for Run. I think these are for corner case situations so it's not needed immediately but maybe just put TODOs to revisit them.

This is more of an FYI than a comment but I noticed that our changes overlap here quite a bit. Overall, I think our approach to resolving pipeline tasks could use a cleaning up since now its OCI images and CustomTasks but who knows what else we will need to resolve in the future.

Yeah, absolutely! I was mostly trying to change as little as possible with this change, and try to keep track of cleanups for future PRs. If you have things in mind could you open an issue to help track them? I can add some smells I've noticed too.
Yeah I agree, AIUI in theory this shouldn't be necessary -- it's updating TaskRun statuses to match the PipelineRun's view, which shouldn't be necessary. It's also kind of gross that TaskRuns are given names before they're ever run, so
This also seems like a smell to me, we're supposed to be enqueueing PipelineRun reconciliations when TaskRun statuses change already, as well as doing periodic reconciliations in case we miss something. (This was introduced in #2573 for context) I'll add a TODO in both cases, but before I do them I'll make sure it's actually necessary at all. |

Is it a TODO for this PR or a follow-up ?
One way would be to do like pipeline resources, aka extracting the run v1alpha1 go api in its own package.

Any reason for not doing if err := c.reconcile(ctx, pr); err != nil { instead ?

I find the following easier to follow that current code.
if _, ok := candidateTasks[t.PipelineTask.Name]; ok {
if t.TaskRun == nil && t.Run == nil {
tasks = append(tasks, t)
}
// […]
}or at least, extracting _, ok := candidateTasks[t.PipelineTask.Name] into its own variable and using it in the if or a switch/case 🙃

This comment seems misplaced — same goes for the one above.. I wonder how it passes the linter 🤔

Changes
Progress toward #3133
This change allows
TaskRefs inPipelineTasks to refer to a non-Tekton ("custom") task type. When such a Pipeline is run, the controller will create a newRunresource that embeds that reference, at which point a custom task controller can take over and begin reconciling that execution, eventually to completion.Followups for future PRs:
PipelineRunStatusis not yet surfaced in thePipelineRunStatussince it currently introduces an import cycle 💣 -- need to moveRunStatustov1beta1even thoughRunis still inv1alpha1.Submitter Checklist
