Issue working with Sentry celery integration

I’m trying to use celery-once with the Sentry celery integration, but I’m running into an issue with how Sentry patches the task tracer.

The issue I’m seeing is that the key before and after the task is patched are different. I believe this is because of how inspect.getcallargs is working with Sentry’s wrapped run method.

Would there be anything wrong with storing the key on the task instance like this:

    def get_key(self, args=None, kwargs=None):
        """
        Generate the key from the name of the task (e.g. 'tasks.example') and
        args/kwargs.
        """
        if not hasattr(self, '_key'):
            restrict_to = self.once.get('keys', None)
            args = args or {}
            kwargs = kwargs or {}
            call_args = getcallargs(
                    getattr(self, '_orig_run', self.run), *args, **kwargs)
            # Remove the task instance from the kwargs. This only happens when the
            # task has the 'bind' attribute set to True. We remove it, as the task
            # has a memory pointer in its repr, that will change between the task
            # caller and the celery worker
            if isinstance(call_args.get('self'), Task):
                del call_args['self']
            self._key = queue_once_key(self.name, call_args, restrict_to)
        return self._key

3.0.1 should resolve this issue. I’ll re-open if anyone else experiences this.

Can you try 3.0.1 and see if that fixes the error? It changes how keys are generated.
