[GitHub] [brooklyn-server] ahgittin opened a new pull request, #1358: Initial workflow implementation
ahgittin opened a new pull request, #1358:
URL: https://github.com/apache/brooklyn-server/pull/1358
Essential structure and sashimi slice of new declarative YAML workflow, per discussion on ML and proposal https://docs.google.com/document/d/1u02Bi6sS8Fkf1s7UzRRMnvLhA477bqcyxGa0nJesqkI
Includes the following:
* no-op and sleep steps
* workflow-effector initializer
* creation and execution of tasks from step definitions
* java and camp yaml tests
many more step types and workflow functionality to be added, but this provides a base where the essential definitions work and subsequent tasks can be done in parallel

Review Comment:
good spot, needs tidying. the `name` of the current step is now available in the `workflowExecutionContext`, and included in some cases, so i think not needed on this api.

Review Comment:
`WorkflowExecutionContext` already does logging for each step, so specific steps only need to log specific behaviour; i think that is enough

the value will be replaced. the declared type is not changed if it was already known.

Review Comment:
Shouldn't the name of the task involve the `name` parameter passed in `newTask` signature?

for debug purposes it would be worth logging the task execution

Review Comment:
Doing a `newSensor` here will overwrite any pre-existing sensor ("regular" or from a previous step), does that matter? Or is it fine because if we are doing a "set" then we are replacing the previous value anyway?

Review Comment:
Duplicate `step1`. This overwrites the first one, so the output from the dump below is just
```shell
Task[myWorkflow]@BD0CgQnH: Completed, no return value (null)
Task[Workflow for effector myWorkflow]@UsCAtiUb: Completed, no return value (null)
Task[step1 - SetSensor]@TDbBaFAD: Completed, no return value (null)
Task[step2 - SetSensor]@qSQZLEGr: Completed, no return value (null)
```
rather than having three steps.
It would be worth detecting duplicate labels and rejecting the workflow.
