awkward has a couple of failing tests related to refcounts. I’m investigating:


___________________________________________________________________________________________________________ test_ArrayBuilder_refcount ____________________________________________________________________________________________________________

def test_ArrayBuilder_refcount():
    builder = ak.highlevel.ArrayBuilder()

  assert (sys.getrefcount(builder), sys.getrefcount(builder._layout)) == (2, 2)

E       assert (1, 2) == (2, 2)
E
E         At index 0 diff: 1 != 2
E         Use -v to get more diff

builder    = 

tests/test_0118_numba_cpointers.py:1005: AssertionError
________________________________________________________________________________________________________________ test_ArrayBuilder ________________________________________________________________________________________________________________

def test_ArrayBuilder():
    builder = ak.highlevel.ArrayBuilder()

  assert sys.getrefcount(builder._layout) == 3

E       AssertionError: assert 2 == 3
E        +  where 2 = (<awkward_cpp.lib._ext.ArrayBuilder object at 0x10ee59e70>)
E        +    where  = sys.getrefcount
E        +    and   <awkward_cpp.lib._ext.ArrayBuilder object at 0x10ee59e70> = ._layout

builder    =

ah, it’s due to PEP 683 – Immortal Objects, Using a Fixed Refcount | peps.python.org.

All good from our side!
