Pylint unendliche Rekursion in Astriod Paket

Question

Ich habe einen folgenden Code-Schnipsel, dass Pylint nicht verarbeiten kann:

from celery import Celery 


def create_celery(application): 
    """ 
    Configures celery instance from application, using it's config 
    :param application: Flask application instance 
    :return: Celery instance 
    """ 
    celery = Celery(application.import_name) 
    celery.conf.update(application.config) 
    TaskBase = celery.Task 

    class ContextTask(TaskBase): 
     abstract = True 

     def __call__(self, *args, **kwargs): 
      with application.app_context(): 
       return TaskBase.__call__(self, *args, **kwargs) 

    celery.Task = ContextTask 
    return celery 

ich folgende Fehlermeldung erhalten:

Ich benutze neueste Pylint 1.5.5 und Python 3.4

Ich habe versucht, logilab auf Issue Tracker zu kontaktieren, aber es scheint, dass sie eine gebrochene Login-Funktionalität haben.

fand ich für diese eine Abhilfe, für diese Datei eine --ignore Option verwenden, aber es löst nicht das Problem

Answer 1

ich dies in meinen Projekten hatte und ich verbrachte eine ganze Weile für das Problem suchen in Astroid. Es stellte sich heraus (für mich), dass Pylint nur zutiefst rekursiv war und das Aufstoßen der Stapelgröße das Problem löst. Also habe ich vor dem Aufruf von pylint Folgendes hinzugefügt (ich rufe pylint vom Komponententestcode an).

# If we don't do this we get stack overflows running pylint!! 
# It's parsing and tests are deeply recursive. 
import sys 
sys.setrecursionlimit(8 * sys.getrecursionlimit()) 

Ich wurde informiert, dass Sie dies auf die pylintrc so hinzufügen können (nicht getestet).

init-hook='import sys; sys.setrecursionlimit(8 * sys.getrecursionlimit())'
