Hi! Thanks for posting this kata.
What are the rules for determining a valid sudoko? From reading the article, it could be that each digit from 1 to 9 should appear once in each of the 9 3x3 subgrids - or maybe each row and column should also contain each digit exactly 1 time, as suggested ny the sentence "For example, the same single integer may not appear twice in the same row, column, or any of the nine 3×3 subregions of the 9×9 playing board"? Maybe there are other constraints (why else starting the sentence with 'For example'?)
Please consider including the rules in the kata description.
Needs random tests.
The tests are very inadequate. Author solution fails on
../bird.txt,images/bird.jpgand possibly many more.A proper solution should be at least as secure as open_basedir, which completely disallows accessing any files outside a base directory.
Moreover, it needs to specify whether paths like
./bird.txtor../upload/bird.txtis allowed. Local file inclusion and directory traversal attack are completely different things, which the author seems to mix up.
