Subject: CircleCI: Test for Python 3 syntax errors and undefined names (#1522)
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=26c5b54fb09fb45e02c9c4618bcea4958c698953;p=platform%2Fupstream%2FlibHarfBuzzSharp.git

CircleCI: Test for Python 3 syntax errors and undefined names (#1522)

Catch missing imports and errors like #1520 and #1521

__E901,E999,F821,F822,F823__ are the "_showstopper_" [flake8](http://flake8.pycqa.org) issues that can halt the runtime with a SyntaxError, NameError, etc. Most other flake8 issues are merely "style violations" -- useful for readability but they do not effect runtime safety.
* F821: undefined name `name`
* F822: undefined name `name` in `__all__`
* F823: local variable name referenced before assignment
* E901: SyntaxError or IndentationError
* E999: SyntaxError -- failed to compile a file into an Abstract Syntax Tree
