[AIRFLOW-4057] Fix bug in stat name validation (#4974)
* [AIRFLOW-4057] Fix bug in stat name validation
The `@validate_stats` wrapper is wrapping an instance method, so it's first
argument is actually an instance of `SafeStatsdLogger`, not the stat_name.
Here's the backtrace that shows up in the webserver logs without the fix:
File "/Users/andrewstahlman/src/incubator-airflow/airflow/www/views.py",
line 86, in <module>
dagbag = models.DagBag(os.devnull, include_examples=False)
File
"/Users/andrewstahlman/src/incubator-airflow/airflow/models/__init__.py", line
312, in __init__
safe_mode=safe_mode)
File
"/Users/andrewstahlman/src/incubator-airflow/airflow/models/__init__.py", line
594, in collect_dags
'collect_dags', (timezone.utcnow() - start_dttm).total_seconds(), 1)
File "/Users/andrewstahlman/src/incubator-airflow/airflow/stats.py", line
85, in wrapper
log.warning('Invalid stat name: {stat}.'.format(stat=stat), err)
Message: 'Invalid stat name: <airflow.stats.SafeStatsdLogger object at
0x10bf194a8>.'
Arguments: (InvalidStatsNameException('The stat_name has to be a string'),)
I've verified the fix by updating the unit tests to exercise the "public"
methods rather than testing the internal validation logic directly.
