Progress Report for Week 7 (July 14 – July 20)

1. What did I get done this week?

  1. Cloned and Analysed 4 Service Template Repositories:
  • zoo-service-template [1]
  • eoepca-proc-service-template [2]
  • eoepca-proc-service-template-wes [3]
  • zoo-argo-wf-proc-service-template [4]
  1. Centralised ExecutionHandler Class:
  • Moved duplicated logic from handler.py in each runner to a single shared ExecutionHandler interface in zoo-runner-common.
  • Created an abstract version using ABC (Abstract Base Class) with required method signatures.
  • All service templates now subclass ExecutionHandler and override their specific logic as needed.
  1. Centralised ZooStub Class:
  • Removed redundant fallback ZooStub definitions in all service templates.
  • Now imported directly from zoo-runner-common.zoostub.

2. Plan for Next Week ( July 21 - July 26 ):

  1. Identify additional common classes and reusable logic across all service templates.

  2. Begin refactoring to centralise this logic in zoo-runner-common.

  3. Set up a GitHub Actions CI pipeline to run unit tests for all CWL runners.

  4. Ensure basic test coverage and integration checks are in place for CI to validate future changes.
