[issue28653] refleak in functools.lru_cache

[Ivan Levkivskyi]

Ivan Levkivskyi added the comment:

FWIW, if I comment out this code

try:
    from _functools import _lru_cache_wrapper
except ImportError:
    pass

in functools.py to use the pure Python version, then I get much larger numbers:

$ ./python -m test -R : test_typing
Run tests sequentially
0:00:00 [1/1] test_typing
beginning 9 repetitions
123456789
.........
test_typing leaked [25003, 25003, 25003, 25003] references, sum=100012
test_typing leaked [9350, 9352, 9352, 9352] memory blocks, sum=37406
test_typing failed
