Catching logs of pytest-flake8 plugin

[GergelyKalmar]

When using the pytest-flake8 plugin the flake logs get catched by pytest-catchlog, making it difficult to see the actual flake error output:

`======== FAILURES ========
_______ FLAKE8-check _______
/home/user/Projects/test/test.py:12:5: F841 local variable 'test' is assigned to but never used

-------- Captured log call --------

========================`

Is there a possibility to turn off flake8 log catching for an entire pytest session with catchlog or would that be possible to add a command line argument for this?

In case someone is looking for a workaround, there is one. You can disable the 'flake8' logger for the entire session by putting an __init__.py file to the root test path directory with the following content:

from logging import getLogger

getLogger('flake8').propagate = False

Actually I also think that this logger should be disabled by default. It's starting to be headache when dealing with not only checking 'tests', where you can put getLogger('flake8').propagate = False to conftest, but when checking module itself. There should be an option not to propagate some logger names, for example:

    add_option_ini(parser,
               '--log-supress',
               dest='log_supress', default=(''),
               help='supress output from the following logger names, delimited by comma.')
    add_option_ini(parser,
               '--log-only',
               dest='log_only', default=(''),
               help='log output only from the following logger names, delimited by comma.')

getLogger('flake8').propagate = False helps (but is pretty annoying to have to add like that)
i get a HUGE amount of logs using pytest-flake8 like:
DEBUG [root] parser.py:346 parsing definition list, current token is tk.NEWLINE (
and i have no idea how to shut them up

I think maybe a more appropriate default logging setting for flake8 would perhaps be 'WARNING'?

You can simply add a conftest.py with the following content:

import logging


def pytest_configure(config):
    """Flake8 is very verbose by default. Silence it."""
    logging.getLogger("flake8").setLevel(logging.WARNING)
