thanks @luzpaz

have a look at https://travis-ci.org/pandas-dev/pandas/jobs/322503804

couple of linting issues (now lines too long) as well as a failing test that checks the error message (you can adjust the test / message).

[luzpaz]

@jreback apologies, i'm having trouble understanding the errors of the tests on TravisCI. Are all of those issues related to this PR ? Can you give me an example of lines that are too long? I'll be happy to fix, I'm not yet down with the lingo. Thank you.

[jreback]

git diff master --name-only -- "*.py" | grep "pandas" | xargs flake8

will show the linting issues

[jreback]

also you need to merge master. and there is 1 test failure as indicated.

[luzpaz]

@jreback After I rebase, should I force push or just create another commit ?

[jreback]

you can force push if you rebase, or simply git merge master and just keep pushing commits.

[jreback]

2nd is prob easier

[jreback]

thanks @luzpaz nice patch!
