It would be good if the patch had a test and I'm not certain of some of the changes done.

I've added two folks who know this code much better than I do (and I'm hoping one of them will look this over).

Yeah, I think we want some test cases for this change.

 +      def check_next_include_order(self, header_type, file_is_header, include_state):
I think we can just use self as include_state?

 +      for line_number in xrange(clean_lines.num_lines()):
It's unfortunate we need to iterate all lines twice. Cannot we implement this by one-pass approach? Maybe it should be like

1. If primary header comes before config.h, emit a warning when we find config.h
2. If primary header isn't found between config.h and "other headers", set has_primary_header=False
3. If primary header is found after we see at least one "other headers", emit a warning.

Simple fix

This fix checks whether primary header exists, and only requires the #include if it does.

Simple fix

What the stylebot said plus a few other things to consider.

> Tools/Scripts/webkitpy/style/checkers/cpp.py:315
> +    def check_next_include_order(self, header_type, file_is_header, has_primary_header):

has_primary_header seems ambiguous to me.

What about primary_header_exists?

>> Tools/Scripts/webkitpy/style/checkers/cpp.py:2600
>> +def _has_primary_header(filename):
> expected 2 blank lines, found 1  [pep8/E302] [5]

Consider: _does_primary_header_exist()

> Tools/Scripts/webkitpy/style/checkers/cpp.py:2602
> +    if the file is not source file or primary header does not exist

Add .

> Tools/Scripts/webkitpy/style/checkers/cpp.py:2608
> +    if os.path.isfile(primary_header):

You could just 
  return os.path.isfile(primary_header)

> Tools/Scripts/webkitpy/style/checkers/cpp_unittest.py:2592
> +        # File with non-existing primary header should not produce errors

Add . after comments (and other places).
