I ended up monkeypatching around this issue for now:
import multidict
class MultiDictProxy(multidict.MultiDictProxy):
def __reduce__(self):
return self.copy().__reduce__()
class CIMultiDictProxy(multidict.CIMultiDictProxy):
def __reduce__(self):
return self.copy().__reduce__()
def monkeypatch_multidict():
multidict.MultiDictProxy = MultiDictProxy
multidict.CIMultiDictProxy = CIMultiDictProxy
from multidict.
Sorry, no.
multidict proxies are modeled after types.MappingProxyType
.
MappingProxyType
is not pickleable, multidict proxies don't support pickling for the same reason.
Your patch breaks consistency:
>>> import pickle
>>> import multidict
>>> d = multidict.MultiDict(a=1, b=2, c=3)
>>> p = multidict.MultiDictProxy(d)
>>> d1, p2 = pickle.loads(pickle.dumps((d, p)))
>>> d2['a'] = 4
>>> assert p2['a'] == 4
A proxy object is just a very bad type for pickling.
Trying to slide through the limitation opens a can of worms.
aiohttp, in turn, is not dedicated to be used in the multiprocessed environment.
Please send through the wire request and response data, not aiohttp objects themself.
