New submission from Jason Vas Dias <jason.vas.d...@gmail.com>:
Hi - I've been experiencing many errors trying to build any version
of Python that will pass its test suite - see issues : #11946 , #11954 -
and now I've been advised to raise bugs about each test failure -
hence this bug. For details of my config and build procedure, please
see : issue #11954 .
So, running the new ./python fails test_import.py :
$ LD_LIBRARY_PATH=`pwd` LD_PRELINK=`pwd`/libpython3.3.so.1.0 \
./python /usr/src/cpython/Lib/test/test_import.py

Thanks for the helpful error backtrace !
This function is somehow failing (test_import.py @ line 545 ):
@unittest.skipUnless(os.name == 'posix',
"test meaningful only on posix systems")
def test_unwritable_directory(self):
# When the umask causes the new __pycache__ directory to be
# unwritable, the import still succeeds but no .pyc file is written.
with temp_umask(0o222):
__import__(TESTFN)
self.assertTrue(os.path.exists('__pycache__'))
self.assertFalse(os.path.exists(os.path.join(
'__pycache__', '{}.{}.pyc'.format(TESTFN, self.tag))))

to assert shouldn't exist really doesn't :
