Generate Counts from input objects with object expansion based on options to learn which objects would would constitute a pack. This step is required to know exactly how many objects would be in a pack while keeping data around to avoid minimize object database access.

A Count object maintains enough state to greatly accelerate future access of packed objects.

• db - the object store to use for accessing objects.
• make_cache - a function to create thread-local pack caches
• objects_ids
  • A list of objects ids to add to the pack. Duplication checks are performed so no object is ever added to a pack twice.
  • Objects may be expanded based on the provided options
• progress
  • a way to obtain progress information
• should_interrupt
• A flag that is set to true if the operation should stop
• options
  • more configuration
