Method annotations incorrectly decorate inherited consumer methods

[prkumar]

Precondition

Consider the following consumer class:

class GitHub(uplink.Consumer):

    @uplink.get("/users/{username}")
    def get_user(self, username):
        """Get a single user."""

Use any method annotation. For this example, I'll create a custom method annotation, PrintMethodName, that simply prints the name of the consumer method that it wraps:

from uplink import decorators

class PrintMethodName(decorators.MethodAnnotation):

    def modify_request_definition(self, method):
        print(method.__name__)

Steps to recreate

Create a subclass of GitHub and decorate it with the method annotation:

@PrintMethodName()
class GitHubSubclass(GitHub):
    pass

Expected

No output to stdout, since GitHubSubclass doesn't define any consumer methods.

Actual

The method annotation decorates get_user from the parent class, GitHub.

Output:

get_user

The root cause here is that uplink.helpers.get_api_definitions returns all consumer methods available to the given class -- including those inherited through the class hierarchy. Any fix for this issue should include a unit test that verifies that MethodAnnotations strictly decorates consumer methods defined in the decorated consumer's body.
