in Lib/ctypes/test/test_loading.py there is the following test
def test_find(self):
for name in ("c", "m"):
lib = find_library(name)
if lib:
cdll.LoadLibrary(lib)
CDLL(lib)
1. on AIX, the test is "broken" because lib is None for both names because:
a1) find_library is basically broken for AIX (needs ldconfig, gcc, and/or other tools not generally available on AIX (production) servers
a2) "m" will always fail because there is no equivalent to libm.so - AIX libm.a only has static members - none are shared.
2. IMHO - the test is misnamed "test_find" - as None is an acceptable answer - which is why it 'appears' to PASS on AIX
As far as library names to look for I suggest switching "m" to "ssl" - as something that should be everywhere.
And the test should be something more like:
self.assertEqual(lib not None)
OR is the test actually testing LoadLibrary and CDLL (as well)
Back to my humble opinion: assuming the real test is to test LoadLibrary and CDLL by accepting None as a valid result from find_library - false POSITIVE is the result when find_library() is not working. |
