Useful Python Tidbits
Project description
Ever find yourself copying and pasting small chunks of Python code between a bunch of your projects? The goal of this library is to reduce or eliminate that problem.
Yes, I realize that’s never going to happen. Contributions are very appreciated though, let’s see how close we can get.
Installation
$ pip install --upgrade tidbits
Note that in an effort to keep this library generalized, optional dependencies are not included, ie. for the Sentry integration you will still need to
$ pip install raven
Usage
GCloud
> requires python-json-logger
Have you ever run an app on Google Cloud and wondered why all your logs were marked as errors, regardless of log level? Well, most likely you weren’t formatting them correctly – Google Cloud expects JSON logs with “severity” rather than “levelname”, which you can set with:
from tidbits.gcloud.log import get_handler
logging.getLogger().addHandler(get_handler())
# or, even better, set all your loggers at once with tidbits.log
Log
Ever had to configure the loggers of all of your dependencies? This one’s for you.
from tidbits.log import get_all_loggers
from tidbits.log import get_all_base_loggers
from tidbits.log import set_handler
from tidbits.log import set_loglevel
import requests
get_all_loggers()
# ['requests', 'urllib3', 'urllib3.connection', 'urllib3.connectionpool', 'urllib3.poolmanager', 'urllib3.response', 'urllib3.util', 'urllib3.util.retry']
get_all_base_loggers()
# ['requests', 'urllib3']
set_handler(myCoolHandler, logger='applesauce')
# the "applesauce" logger uses this (and only this) handler
set_handler_globally(myCoolHandler)
# all loggers use this (and only this) handler
set_handler_globally(myCoolHandler, ignore={'aardvark', 'banana'})
# all loggers except those listed use this (and only this) handler
set_loglevel(debug=True)
# sets logging.getLogger() to DEBUG and all others to INFO
set_loglevel(debug=False)
# sets logging.getLogger() to INFO and all others to WARNING
Integrations
> requires raven
Do you use Sentry? I do. And every single project I use it in contains the same block for configuring it from the SENTRY_DSN environment variable and the same block for instrumenting the error logger.
from tidbits.integration.sentry import SENTRY
from tidbits.integration.sentry import instrument_logger
try:
{}['missing_key']
except Exception:
# damn, I totally didn't expect an error here, better send it to Sentry
SENTRY.captureException()
# creates events in Sentry for each error log
instrument_logger(level=logging.Error)
