Let's make test_fd_transfer_windows a bit less hangy by polling for up to 60
seconds instead of simply trying to recv() and by terminating before trying to
join().
@unittest.skipUnless(HAS_REDUCTION, "test needs multiprocessing.reduction")
@unittest.skipIf(sys.platform != "win32", "Windows-only test")
def test_fd_transfer_windows(self):
if self.TYPE != 'processes':
self.skipTest("only makes sense with processes")
conn, child_conn = self.Pipe(duplex=True)
p = self.Process(target=self._check_handle_access, args=(child_conn,))
p.daemon = True
p.start()
try:
with open(test.support.TESTFN, "wb") as f:
self.addCleanup(test.support.unlink, test.support.TESTFN)
handle = msvcrt.get_osfhandle(f.fileno())
parent_access = get_handle_info(handle).GrantedAccess
reduction.send_handle(conn, handle, p.pid)
if not conn.poll(timeout=60):
raise AssertionError("could not receive from child process")
child_access = conn.recv()
self.assertEqual(parent_access, child_access)
finally:
p.terminate()
p.join()
