CD2: Enable logging in Python script

[tyler_clair]

With the CLI DAP client you can add the optional argument to increase the loglevel. Is there a way to propagate the logging into my own python scripts?

DAP client library uses the Python module logging. DAP client library functions inherit any configuration you set on the module logging if you interact with classes and functions defined in the client interface defined in api.py.

In fact, DAP command-line interface is a thin wrapper around the programmatic interface; it configures the Python module logging based on command-line arguments before it invokes the appropriate function in api.py.

Thanks Levente,

I did get logging to work, the DAP client library uses the root handler rather than a named handler which confused me at first. Is there any plans in the future to put it under a named handler? I had to move my apps logging to the root handler as well to avoid logging events twice.

For those interested here is my logging configuration, I rotate logs each day at midnight.

import logging
from logging.handlers import TimedRotatingFileHandler

# Default logging level
logging_level = logging.INFO

# Logging setup
logger = logging.getLogger()
logger.setLevel(logging_level)

# Rotating file handler that rotates at midnight
log_file = os.path.join("cd2-downloader.log")
handler = TimedRotatingFileHandler(log_file, when="midnight", backupCount=7)
formatter = logging.Formatter("%(asctime)s - %(name)s - %(levelname)s - %(message)s")
handler.setFormatter(formatter)
logger.addHandler(handler)

# Root logger settings
# Disable propagation for the root logger
logging.getLogger().propagate = False
logging.getLogger().setLevel(logging_level)
logging.getLogger().addHandler(handler)

DAP client library has been updated to use the named logger dap instead of the root logger. This change will likely be included in the next release of the DAP client library.
