Alpine linux 3.15 on pypy3 test_52_numeric_ops_float fails

ERROR: test_52_numeric_ops_float (__main__.test_pyprotect)
----------------------------------------------------------------------
Traceback (most recent call last):

AttributeError: 'CF' object has no attribute '__ceil__'. Did you mean: __bool__?

The same test does not fail on PY3 / PY2 / PYPY2 on ubuntu jammy

[sundarnagarajan]

• ceil() and floor() work on int (test_51_numeric_ops_int)
• ceil() and floor() work on CF class derived from float, but
• Proxy does not see __ceil__ or __floor__ methods in CF object

On Alpine Linux, on PYPY, ceil() and float() depend on something other than or more than __ceil__ and __floor__ methods

Workaround (for test failing):

if hasattr(n1, '__ceil__') and hasattr(n1, '__floor__'):
    res1 = (ceil(n1), floor(n1))
    res2 = (ceil(w1), floor(w1))
    assert(res2 == res1)

Keeping this issue open.

This is a surprising behavior in pypy3, and a behavior that specifically manifests on Alpine Linux (and not Ubuntu). This cannot be written off as "Python2 - will not fix".
