Eval is a big problem, to be more rigorous inspection, and the rest of course can not be completely ignored.
However, this check is only to provide reference, you can not say because it prompted you do not have to dirname it, such as dirname (__file__) This certainly no security risks, so the specific problem specific analysis.

Moreover, this thing feeling is not reliable, is to make a full-text search according to Dirname,link,eval? What's the point?
