KeyError: "Attempt to overwrite 'args' in LogRecord"

Expected result:

I am able to use args as keyword to denote argument to string interpolation when using loguru

Actual result:

Opposite of above 😉.In fact it seems that if you try to specify whatever is originally available in Record from logging of python, python will think you are crazy to put such things in record.

Facts

• loguur.__version__ = 0.5.0
• python --version = Python 3.7.6
• lsb_release -sd = Linux Mint 19.3 Tricia
• context = application

Reproduce

git clone https://github.com/kornicameister/axion.git /tmp/axion --depth 1 ; \
cd /tmp/axion ; \
git checkout c9d85e76bd48719aab7edded1d4287a52ecb145e \
command -v tox && tox -e "py37-test" -- -k test_not_empty_signature || echo "need tox" ; \
cd - \
rm -rf /tmp/axion

Root cause

Relevant line that causes issue available here

Alternatively, it might be caused by conftest#caplog here, but this is unlikely given that only one test fails 😉

So, I modified the way the LogRecord is filled with extra.

The main downside is that it’s no longer possible to use Formatter("[%(some_extra_field)s] %(message)s") with standard logging handler, but I think it’s certainly less of a problem than the "Attempt to overwrite" error was.

Closing thie issue consequently. Discussion about mypy plugins moved here: #277

There exists type hints for loguru, anyone should be able to benefit from it using mypy, right?

I opened https://github.com/kornicameister/axion/issues/328 to discuss usage of loguru in your project. 😃
