Strawberry-graphql

--------------------

Add `GraphQLWebsocketCommunicator` for testing websockets on channels.
i.e:

python
import pytest
from strawberry.channels.testing import GraphQLWebsocketCommunicator
from myapp.asgi import application


pytest.fixture
async def gql_communicator():
async with GraphQLWebsocketCommunicator(
application=application, path="/graphql"
) as client:
yield client


async def test_subscribe_echo(gql_communicator):
async for res in gql_communicator.subscribe(
query='subscription { echo(message: "Hi") }'
):
assert res.data == {"echo": "Hi"}

--------------------

This release adds support for specialized generic types.
Before, the following code would give an error, saying that `T` was not
provided to the generic type:

python
strawberry.type
class Foo(Generic[T]):
some_var: T


strawberry.type
class IntFoo(Foo[int]): ...


strawberry.type
class Query:
int_foo: IntFoo


Also, because the type is already specialized, `Int` won't get inserted to its name,
meaning it will be exported to the schema with a type name of `IntFoo` and not
`IntIntFoo`.

For example, this query:

python
strawberry.type
class Query:
int_foo: IntFoo
str_foo: Foo[str]


Will generate a schema like this:

graphql
type IntFoo {
someVar: Int!
}

type StrFoo {
someVar: String!
}

type Query {
intFoo: IntFoo!
strfoo: StrFoo!
}

Fix missing custom `resolve_reference` for using pydantic with federation

i.e:

python
import typing
from pydantic import BaseModel
import strawberry
from strawberry.federation.schema_directives import Key


class ProductInDb(BaseModel):
upc: str
name: str


strawberry.experimental.pydantic.type(
model=ProductInDb, directives=[Key(fields="upc", resolvable=True)]
)
class Product:
upc: str
name: str

classmethod
def resolve_reference(cls, upc):
return Product(upc=upc, name="")

--------------------

This release fixes a bug in subscriptions using the graphql-transport-ws protocol
where the conversion of the NextMessage object to a dictionary took an unnecessary
amount of time leading to an increase in CPU usage.
