qtm_rt affects the root logger

[weeebber]

Hello, when importing qtm_rt (qtm_rt/__innit__.py) it is affecting the root logger rather than the expected "qtm_rt" logger.
This therefore causes all subsequent logging calls from my program to duplicate output.

The following lines are the cause:

LEVEL = logging.DEBUG if LOG_LEVEL == "debug" else logging.INFO
logging.basicConfig(level=LEVEL, format="%(asctime)s - %(name)s - %(levelname)s - %(message)s")

Considering you are calling LOG = logging.getLogger("qtm_rt"), I dont think this was intended behaviour.

The following will correct the code to the expected behaviour:

LOG = logging.getLogger("qtm_rt")
LOG_LEVEL = os.getenv("QTM_LOGGING", "DEBUG")

# WIP - sanity check LOG_LEVEL?
# As of Python 3.2 you can use the string rather than level numeric value (i.e. DEBUG = 10)

# Configure qtm_rt logger
LOG.setLevel(LOG_LEVEL)

# Console handler with custom formatter
LOG_CONSOLE_HANDLER = logging.StreamHandler()
LOG_CONSOLE_HANDLER.setLevel(LOG_LEVEL)
LOG_CONSOLE_HANDLER.setFormatter(logging.Formatter("%(asctime)s\t%(levelno)s %(levelname)s\t%(filename)s\t%(funcName)s\t%(message)s"))
LOG.addHandler(LOG_CONSOLE_HANDLER)

And then in my program I can do the following. The below might be worth mentioning on the front page of the docs.

# Set QTM logging level to ERROR before importing
os.environ["QTM_LOGGING"] = "ERROR"
import qtm_rt
