There's a proposal for a fix inconsistency of logger mechanism.
See below.
Example 1.
---------------------------------------------------
import logging
app_logger = logging.getLogger('app')
app_logger.error('foo')
logging.error('goo')
app_logger.error('foo')
---------------------------------------------------
result:
foo
ERROR:root:goo
ERROR:app:foo
---------------------------------------------------
You can see the inconsistency of app_logger results.
Example 2.
---------------------------------------------------
import logging
stream_handler = logging.StreamHandler()
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
stream_handler.setFormatter(formatter)
app_logger: logging.Logger = logging.getLogger('app')
app_logger.setLevel(logging.ERROR)
app_logger.addHandler(stream_handler)
app_logger.critical('foo')
logging.critical('goo')
app_logger.critical('foo')
---------------------------------------------------
results:
2018-05-04 11:21:15,199 - app - CRITICAL - foo
CRITICAL:root:goo
2018-05-04 11:21:15,200 - app - CRITICAL - foo
CRITICAL:app:foo
---------------------------------------------------
You can see even inconsistency of app_logger`s outputs count.
So I have some proposals for fix it.
Proposal 1.
Remove implicit calling `basicConfig`. Then you can get the consistent results.
Result of the example 1.
foo
goo
foo
Result of the example 2.
2018-05-04 11:31:36,069 - app - CRITICAL - foo
goo
2018-05-04 11:31:36,070 - app - CRITICAL - foo

Proposal 2.
Add calling `basicConfig` in `callHandlers` method if the root logger has no handler.
Result of the example 1.
ERROR:app:foo
ERROR:root:goo
ERROR:app:foo
Result of the example 2.
2018-05-04 11:36:45,318 - app - CRITICAL - foo
CRITICAL:app:foo
CRITICAL:root:goo
2018-05-04 11:36:45,319 - app - CRITICAL - foo
CRITICAL:app:foo
