As suggested by @balloob, this PR reworks the logbook a bit to keep less data in memory. This is done with a generator function that yields just the events that are not excluded rather than keeping the entire result set in memory (twice, I think).

In my limited testing, memory usage decreases significantly while the running time remains similar.


  • The code change is tested and works locally.
  • Local tests pass with tox.
  • There is no commented out code in this PR.

If the code does not interact with devices:

  • Tests have been added to verify that the new code works.
