Weekly QA work

During our reproducibility testing, FTBFS bugs have been detected and reported by:

diffoscope development

  • Refactor Presenter to a singleton manager
  • Drop passing has_differences around, fixing an issue with generating files called ‘-‘
  • Prevent abstraction-level violation by defining visual diff support on the Presenter classes.
  • Split output and configuration of presenters.
  • Refactor html and text presenters so they fit the same Presenter interface.

strip-nondeterminism development

• Bernhard M. Wiedemann:
  • make get_normalizer_by_name O(1)
  • only call get_normalizer_by_name once
