Trigger deadline events manually

Deadline
1

Hi all,
We have the following case:

  • we have some nice procedures for processing renders, which get applied in OnJobStarted, OnJobFinished, etc.
  • we would like to invoke the same procedures manually on existing renders, preferably on the farm, in order to offload the process from the workstation.
  • essentially we need to call OnJobStarted and OnJobFinished in order, bypassing any rendering.

In order to achieve this, I first tried instantiating an event listener inside a script, by

listener = ProcessRenderEventListener()

Then I synthetically created a job and submitted it to the repo.
However, when I ran listener.OnJobStarted(job), I got

    Error: NullReferenceException : Object reference not set to an instance of an object.
   at Deadline.Events.DeadlineEventListener.LogInfo(String message)
  File "e:\DeadlineRepository10\custom\scripts\Submission\SubmitHoudiniFlipbook.py", line 58, in __main__
    listener.OnJobStarted(newJob)
  File "e:/DeadlineRepository10\custom\events/ProcessRender\ProcessRender.py", line 457, in OnJobStarted
    self.LogInfo("Using scene file to get toolkit: {}".format(scene_path))

  ---------- Inner Stack Trace ----------
   at Deadline.Events.DeadlineEventListener.LogInfo(String message)

Which seems to imply that the self reference inside the method is null when calling self.LogInfo.

Creating a listener manually is only one way to achieve what we want, so I’m asking for suggestions.
Here are some more options:

  • create a new “bypass”/dummy render plugin, which will call CompleteJob inside its StartJobCallback
  • in the event plugin, call CompleteJob once OnJobStarted is done, and if some conditions are met.
