t2.clear(upstream=True)
ti1.run()
ti2.run()
self.assertEqual(ti1.try_number, 2)
# max_tries is 0 because there is no task instance in db for ti1
# so clear won't change the max_tries.
self.assertEqual(ti1.max_tries, 0)
self.assertEqual(ti2.try_number, 2)
# try_number (0) + retries(1)
self.assertEqual(ti2.max_tries, 1)
