Yesterday flake8 released a new version (3.5.0) that now brings a newer pyflakes (1.6.0) that introduces a new feature:
Find Python files without extensions by their shebang
The new flake8 loads also some additional pycodestyle plugins by default:
pycodestyle.ambiguous_identifier pycodestyle.bare_except
As a result, files that before were not checked might now be checked and with the additional check files that were passing might not pass anymore.
As a quick workaround we forced an older flake8 version in https://gerrit.wikimedia.org/r/#/c/386139/
but we need to go over those files and fix the issue or ignore the files if they are not internally developed and just imported from elsewhere.
The other approach could be to just disable the checks E722 and E741.
The list of offending files is:
