New submission from Pascal Chambon <[email protected]>:
My own fileio implementation fails against the latests versions of the io test
suite, under python2.6, because these now require FileIO objects to accept
unicode strings in their write methods, whereas the doc mentions raw streams
only deal with bytes/bytearrays.
Below is the faulty test (unicode literals or ON). The unicode "xxx" is written
to the io.FileIO instance, and the stdlib implementation indeed accepts unicode
args (in _fileio.c : "if (!PyArg_ParseTuple(args, "s*", &pbuf)...").
In test_io.py :
def test_destructor(self):
record = []
class MyFileIO(io.FileIO):
def __del__(self):
record.append(1)
io.FileIO.__del__(self)
def close(self):
record.append(2)
io.FileIO.close(self)
def flush(self):
record.append(3)
io.FileIO.flush(self)
f = MyFileIO(test_support.TESTFN, "w")
f.write("xxx")
del f
self.assertEqual(record, [1, 2, 3])
