python logging file is not working when using logging.basicConfig

Solution 1:

I found out what the problem was. It was in the ordering of the imports and the logging definition.

The effect of the poor ordering was that the libraries that I imported before defining the logging using logging.basicConfig() defined the logging. This therefore took precedence to the logging that I was trying to define later using logging.basicConfig()

Below is how I needed to order it:

import logging
## for file logging
logging.basicConfig(filename='server-soap.1.log',
        level=logging.INFO,
        format='%(asctime)s %(levelname)s %(threadName)-10s %(message)s',)

from pysimplesoap.server import SoapDispatcher, SOAPHandler
from BaseHTTPServer import HTTPServer
import time,random,datetime,pytz,sys,threading
from datetime import timedelta
#DB
import psycopg2, psycopg2.extras
from psycopg2.pool import ThreadedConnectionPool

#ESB Call
from suds import WebFault
from suds.client import Client

But the faulty ordering that I initially had was:

from pysimplesoap.server import SoapDispatcher, SOAPHandler
from BaseHTTPServer import HTTPServer
import logging
import time,random,datetime,pytz,sys,threading
from datetime import timedelta
#DB
import psycopg2, psycopg2.extras
from psycopg2.pool import ThreadedConnectionPool

#ESB Call
from suds import WebFault
from suds.client import Client

## for file logging

logging.basicConfig(filename='server-soap.1.log',
        level=logging.INFO,
        format='%(asctime)s %(levelname)s %(threadName)-10s %(message)s',)

Solution 2:

"Changed in version 3.8: The force argument was added." I think it's a better choice for new version.

For older Version(< 3.8):

From the source code of logging I found the flows:

This function does nothing if the root logger already has handlers

configured. It is a convenience method intended for use by simple scripts
to do one-shot configuration of the logging package.

So, if some module we import called the basicConfig() method before us, our call will do nothing.

A solution I found can work is that you can reload logging before your own calling to basicConfig(), such as

def init_logger(*, fn=None):

    # !!! here
    from imp import reload # python 2.x don't need to import reload, use it directly
    reload(logging)

    logging_params = {
        'level': logging.INFO,
        'format': '%(asctime)s__[%(levelname)s, %(module)s.%(funcName)s](%(name)s)__[L%(lineno)d] %(message)s',
    }

    if fn is not None:
        logging_params['filename'] = fn

    logging.basicConfig(**logging_params)
    logging.error('init basic configure of logging success')
