Description Geoffrey Garen 2014-03-21 18:58:02 PDT

Some #includes are obvious layering violations.

For example, no file in WebCore/platform should ever #include any WebCore file outside WebCore/platform.

It would be nice to codify this in a simple script.

See, for a motivating example, https://bugs.webkit.org/show_bug.cgi?id=130275.

Should we start generating separate forwarding headers for the platform layer?

Cross-inclusion of <Platform/Header.h> in WebCore would be allowed at first, but it would extremely simplify locating these layering violations.

I meant the other way around, that is including <WebCore/Header.h> in the platform layer.

In my opinion if we could get rid include paths (as blink did it),
it's obvious to catch layering violations by anybody without any
sophisticated script and style checker. But unfortunately there were
many objections against relative includes to Source.
