Debug mode assumes coroutine callables have __name__
On python 3.4.3, the following code will work when running without debug mode
enabled, and raise an exception when run with PYTHONASYNCIODEBUG=1:
import asyncio
import functools
@asyncio.coroutine
def func(x, y):
print('func with x = {} and y = {}'.format(x, y))
yield from asyncio.sleep(0.1)
print('exit func')
partial_func = asyncio.coroutine(functools.partial(func, 1))
loop = asyncio.get_event_loop()
try:
loop.run_until_complete(partial_func(2))
finally:
loop.close()
Line 154 of asyncio.coroutines tries to copy some attributes of the wrapped
function to its CoroWrapper instance, which fails because the partial object
has no __name__:
AttributeError: 'functools.partial' object has no attribute '__name__'
