@graingert any suggestions on how to make this scoped to a single module?

You'll have to talk to @vstinner on how to get per module resource warnings

You can dig out the original owner of the object via tracemalloc but it slows down python considerably, The issue being tracemalloc is great and gives you all the info you need, but it's too slow to run all the time, also resources warnings are flakey which means by the time you see one it's too late and you weren't running tracemalloc

What I think should happen is that:

  • When any object with a custom __del__ is being constructed
  • If the ResourceWarning filter is configured as "error"
  • the frame module, filename and line number 2 frames above the last __init__ call is recorded, as a sort of tracemalloc of last-resort

Then when the ResourceWarning is raised it's associated with those lines
