It's not "OpenStack CI's flake8" version. Nova's master branch is getting flake8 transitively through its test-requirement on hacking!=0.13.0,<0.14,>=0.12.0 which is causing it to select hacking==0.12.0 (the only version between 0.12.0 and 0.14.0 is 0.13.0 which is explicitly skipped). In turn, that version of hacking declares a requirement on flake8<2.6.0,>=2.5.4 which is causing it to use flake8==2.5.5. As you noted, that depends on pep8!=1.6.0,!=1.6.1,!=1.6.2,>=1.5.7 so pep8==1.7.1 gets used. > flake8 version isn't managed by g-r, but that's another story. [...] The reason we don't globally-constrain hacking, flake8 or other static analyzers is that projects are going to want to comply with new rules at their own individual paces; it's up to the Nova team to decide when to move their master branch testing to new versions of these. Per the example above if they upped their hacking cap to <1.2 they would get hacking==1.1.0 (the latest release) which would install flake8==2.6.2 and so pycodestyle==2.0.0. -- Jeremy Stanley
