You should be able to make a layout test for this, using window.internals.pagination.

> +        return columnInfo()->columnHeight();

Why can’t RenderView be the one overriding this function? If we’re not a RenderView, isRenderView() is going to return false anyway.

> Source/WebCore/rendering/RenderBlock.h:199
> +    virtual LayoutUnit availableLogicalHeight() const;

This override (though I think it will go in RenderView.h) should be annotated with the OVERRIDE macro.

Since this is a JavaScript API, you can just add pageLength as an optional parameter to the existing function. Existing tests that don’t pass anything will behave as if they’d passed 0, I think, which is fine because 0 is the default value anyway.
