PI89045: COMPONENT VERSION CREATION AND DEPLOYMENT RACE CONDITION

APAR status

• Closed as program error.

Error description

• It is possible for a component to be deployed before it is
  finished being imported into Codestation.
  
  To reproduce:
  1. Create an application that deploys by downloading a component
  version's artifacts from codestation. ("Download Artifacts").
  2. Run a version import for that component such that it takes a
  long time (minutes) to complete You may accomplish this by
  throttling the network between the import agent and the UCD
  server, or you may simply use a use a very large file.
  3. While the import is running and not yet completed, run a
  deployment process, selecting the "Latest Version" of the
  component.  Notice that the (essentially uncompleted) version is
  selected.
  4. Notice that the Download Artifacts step fails.
  5. Notice that the version import now fails as well.
  

Local fix

• 1) Introduce a delay between a version import and the download
  artifacts step in deployment.  You would use the "wait"
  process step.  How much of a delay you need to use will take
  some experimenting to determine.
  
  2) Use status gates to ensure that a certain
  status of a component version is set before triggering the
  deployment.
  
  3) Certain UCD plugins can download artifacts directly from
  source artifact repositories.  This can eliminate the need to
  duplicate files in Codestation.
