Can't stop celery printing the builtin task functions... no idea what is causing this.

[techdragon]

I've been debugging the entire init process to try and work out what the heck is going on here... but Celery is printing this stuff when the worker starts, and when I queue a shared task... I just don't understand what is printing this and its driving me mad... I started adding signal hooks to print information so I could try to work out where in the process it begins, so the worker startup contains some debug printing signal hook output that might help.

From what I can tell... its printing the function arguments of the tasks as they are loaded... and while it could be something in some package I'm using... and I'm happy to inspect all the code of all my dependencies... I just can't find the signal or import hook or whatever it is that is causing this to even begin that debugging process

When I queue a shared task for the first time and only the first time...

def xmap(task, it):
    return 1


def chain(*args, **kwargs):
    return 1


def backend_cleanup():
    return 1


def xstarmap(task, it):
    return 1


def chord(self, header, body, partial_args=0, interval=1, countdown=2, max_retries=3, eager=4, **kwargs):
    return 1


def accumulate(self, *args, **kwargs):
    return 1


def chunks(task, it, n):
    return 1


def unlock_chord(self, group_id, callback, interval=0, max_retries=1, result=2, Result=3, GroupResult=4, result_from_tuple=5, **kwargs):
    return 1


def create_or_update_my_background_task(word, targets):
    return 1


def group(self, tasks, result, group_id, partial_args, add_to_parent=0):
    return 1

And when the worker is started up it prints this.

 <project_dir> % celery -A <project_name> worker -l INFO

Try using the quiet option, as in: celery --quiet worker.

I've just tested --quiet and all that does is hide the banner prompt... I'm still seeing all the function signatures getting printed.
