Python retry package - tenacity : How to log the root cause of exception?
1
As discussed in this question I am using tenacity to do retries.
A toy code looks like below
import logging
from tenacity import retry
import tenacity
@retry(wait=tenacity.wait_incrementing(start=10, increment=10, max=100), stop=tenacity.stop_after_attempt(3))
def print_msg():
logging.info('Hello')
logging.info("World")
raise Exception('Test error')
if __name__ == '__main__':
logging.basicConfig(
format='%(asctime)s,%(msecs)d %(levelname)-8s [%(filename)s:%(lineno)d] %(message)s',
datefmt='%d-%m-%Y:%H:%M:%S',
level=logging.INFO)
logging.info('Starting')
print_msg()
The output looks like below
21-11-2018:12:40:48,586 INFO [retrier.py:18] Starting
21-11-2018:12:40:48,586 INFO [retrier.py:8] Hello

raise value
RetryError: RetryError[<Future at 0x109fa6150 state=finished raised Exception>]
Can someone let me know how can I log the root cause of the exception?

you could use reraise=True option, there is no verbose doc, but you could read its source:
...
File "53406953.py", line 10, in print_msg
raise Exception('Test error')
Exception: Test error
