获得“意外提升：BdbQuit()”

Question

追溯：

[2014-09-16 17:27:04,912: ERROR/MainProcess] Task my_project.tasks.get_items[8481cd42-ec19-441f-b32d-03280570053c] raised unexpected: BdbQuit()

BdbQuit

我检查了这个问题并尝试使用celery.contrib.rdb但在执行 telnet 后我被发送到：

vagrant@vagrant-ubuntu-trusty-64:~$ telnet localhost 6900
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
--Call--

-> def __exit__(self, type, value, traceback):
(Pdb) l
 16             try:
 17                 return self.gen.next()
 18             except StopIteration:
 19                 raise RuntimeError("generator didn't yield")
 20     
 21  ->     def __exit__(self, type, value, traceback):
 22             if type is None:
 23                 try:
 24                     self.gen.next()
 25                 except StopIteration:
 26                     return
(Pdb)

代码是：

from __future__ import absolute_import
from celery import shared_task
from . import utils
from . import status
import redis
import pickle
import logging
from django.conf import settings
import tweepy
from celery.contrib import rdb

logging.basicConfig(level=logging.DEBUG, format='%(asctime)s - %(levelname)s -%(filename)s:%(lineno)d - %(message)s')

MAX_TWEETS_PER_PAGE = 200

r = redis.StrictRedis(host='localhost', port=6379, db=0)

@shared_task
def get_items(user_id, external_page):
    rdb.set_trace()
    logging.debug('{} {}'.format(settings.API_KEY, settings.API_SECRET))
    logging.debug('{} {}'.format(settings.ACCESS_TOKEN, settings.ACCESS_TOKEN_SECRET))

到目前为止，如果我删除 set_trace 调用，任务将成功结束，但我需要能够调试它，因为我将添加更多内容。任何帮助，将不胜感激。
