feat: support to produce results from a failed task #6510

pritidesai · 2023-04-07T21:53:07Z

Changes

If the task fails or succeeds, as long as the task result is initialized, it can be successfully parsed and can be referenced by the final task.

This commit enables the failed task to produce the task results, and the final task can reference it.

Closes #5749

This is a duplicate of #5750 but with conflicts resolved and e2e test. I was reviewing PR #5750 and decided to create an e2e test. After noticing it had merge conflicts, decided to resolve them and create this PR. @cugykw is now a co-author of this commit.

looks like a flake, at least one of them didn't fail earlier:

test: TestTaskResultsFromFailedTasks expand_more | 6s
test: TestPipelineTaskTimeout expand_more

Was able to run TestTaskResultsFromFailedTasks with alpha flag.

So the alpha test failure is not a flake 😞

But it is interesting that the same test succeeds with stable and beta integration test check.

The logs of tests with stable: https://storage.googleapis.com/tekton-prow/pr-logs/pull/tektoncd_pipeline/6510/pull-tekton-pipeline-integration-tests/1644479150448185344/build-log.txt

The logs of tests with alpha: https://storage.googleapis.com/tekton-prow/pr-logs/pull/tektoncd_pipeline/6510/pull-tekton-pipeline-alpha-integration-tests/1659248641593839616/build-log.txt

The difference is:

With stable only one task is skipped as expected:

Message:            "Tasks Completed: 2 (Failed: 1, Cancelled 0), Skipped: 1",

With alpha, the final task which was expected to execute is skipped with the reason "Results were missing":

Message:            "Tasks Completed: 1 (Failed: 1, Cancelled 0), Skipped: 2",

pritidesai · 2023-05-18T20:48:11Z

hey @chitrangpatel, do you think the configuration of RESULTS_FROM=sidecar-logs could be causing a final task to skip if the dependent task fails?

I think you need to do the same thing in line 185 as well.

That will account for the same change when fetching results from sidecar logs too.

thanks a bunch @chitrangpatel for a quick response 🙏 hopefully works now 🤞
