Changes

Features

• :sparkles: TEP-0090: Fan Out (#4990)

A PipelineTask with a Matrix is fanned out into parallel TaskRuns which are executed in parallel.

• :sparkles: Complete implementation of image pull failure handling (#4952)

The TaskRunImagePullFailed logic now covers sidecars, and the error message includes the step name and the image

• :sparkles: TEP-0090: Matrix - Concurrency Control (#4947)

The default maximum count of TaskRuns or Runs from a given Matrix is 256. Users can configure this value for their installations.

• :sparkles: TEP-0090: Add Matrix Package (#4934)

• :sparkles: [TEP-0076]Support Results Array Indexing (#4911)

Support indexing array results substitution as an alpha feature.

A task can specify a type to produce array result, such as:

results: - name: array-results type: array description: The array results

And the task script can populate result in an array form with:

echo -n "["hello","world"]" | tee $(results.array-results.path)

and we can refer to the array results elements via index in param like: params: - name: foo value: "$(tasks.task1.results.array-results[1])"

This feature is part of the TEP-0076.

• :sparkles: [TEP-0075] Validate task result variable of object type (#4878)

• :sparkles: [TEP-0075] Validate against using the whole object in task steps (#4861)

• :sparkles: TEP-0090: Matrix - Implement isRunning (#4981)

• :sparkles: TEP-0090: Matrix - Implement isSuccessful (#4980)

• :sparkles: TEP-0090: Failure Strategies - Remove Fail Fast (#4972)

• :sparkles: TEP-0090: Get Names of TaskRuns (#4958)

• :sparkles: TEP-0090: Add TaskRuns to ResolvedPipelineRunTask and implement isFailure (#4951)

• :sparkles: TEP-0090: Indicate Resolved PipelineRunTask is Matrixed (#4945)

• :sparkles: TEP-0090: Split up ResolvePipelineRunTask (#4943)
