Presently if one of the task in pipeline is consuming result from the previous task but the previous failed to produce the result then pipeline fails without running the finally tasks. These changes handles tasks which got failed in the validation step. Signed-off-by: divyansh42 <diagrawa@redhat.com>

@afrittoli, I have made the changes as per the discussion that happened over the Slack channel. Could you please take a look again? |

I guess the reason for failure will be available at TaskRun level, is that right?

I was also concerned about not showing the exact reason for the failure. When I checked in the implementation inside the GetPipelineConditionStatus function, it gave status based on failed, and success. So it is more generalized.
The status will not be available at the TaskRun level as TaskRun will not be created.
Do you have any suggestions to deal with this in a better way so that we can have a proper reason for the failure?
Earlier we were failing right away so we were getting the exact error.

One idea that I can think of is to have ValidationFailed as a map where it will store failed tasks along with the reason and inside the GetPipelineConditionStatus function we can have a check for the ValidationFailed and add the status accordingly.
If this looks good, I can try the implementation.

One question that comes with this approach is when setting the reason in GetPipelineConditionStatus is how to decide the reason for the multiple Validation Failed Task.
May be we can set this to a generic error like https://github.com/tektoncd/pipeline/blob/main/pkg/apis/pipeline/v1/pipelinerun_types.go#L385

Fixes: #7330
Changes
Presently if one of the tasks in the pipeline is consuming results from the previous task but the previous task failed to produce the result then the pipeline fails without running the
finallytasks.These changes handle tasks that failed in the validation step by adding it to the new field named
ValidationFailedTasksunder structPipelineRunFactswhich will have all the tasks for which the taskrun is not created as it failed in the validation step by the controller.These changes will also remove the logic of panic errors occurring if any of the validation fails. Instead of the controller returning a permanent error, it will remove all the tasks that have to be scheduled. This also changes the skip logic to skip the task and stop running the pipeline if any of the validation is failed.
