This:
- updates the pre-commit configuration and setup.py testing dependencies
- updates isort/flake8 configuration for black
- adds black linting to Makefile and CircleCI configuration
- updates editorconfig with the new line length (88) for py files
- updates python guidelines in docs
Ref #6463, #6428
* pin isort to 5.6.4
* update isort version mentioned in python_guidelines.rst
* make lint commands consistent between make lint and circleci
* fix isort errors on files outside of /wagtail
* speed up isort by ignoring additional directories and filetypes
D200: One-line docstring should fit on one line with quotes
D202: No blank lines allowed after function docstring
D204: 1 blank line required after docstring
D205: 1 blank line required between summary line and description
D209: Multi-line docstring closing quotes should be on a separate line
No occurances of any of these exist in Wagtail at the moment
This adds a conftest.py module to setup the test infrastructure
correctly. It doesn't yet add pytest and pytest-django to the testing
requirements so for now it is completly optional.
This change also updates the test_migrations testcase to use a regular
TestCase baseclass instead of the TransactionTestCase. Otherwise the
following tests fail with db errors.
Drone will now check that
from __future__ absolute_import, unicode_literals
is part of every Python source file, to ensure a consistent experience
across all versions of Python.
See #2392 for an instance where missing `unicode_literals` was causing
problems.
Add missing absolute_import, unicode_literals to all files
Explicitly ensure strings are of the correct types
Now that unicode_literals is in every file, some things that used to
be py2 `str`s were now `unicode` instead. This caused issues with
generated class / function names, which must be `str` in all versions of
Python. This means bytes in py2, and unicode in py3. A test also checked
for the incorrect type of SafeString. HTML content should always be
unicode, so this has been fixed.
