The change looks fine to me.

Wouldn't be clearer to assert whether "items placement" is completed ? instead of this negative clause.

> Source/WebCore/rendering/RenderGrid.cpp:2279
> +    Grid& grid = sizingData.grid();

const ?

> Source/WebCore/rendering/RenderGrid.cpp:2796
> +    ASSERT(!m_grid.needsItemsPlacement());

ditto.
Why we don't need to comment this assert out ?

> Source/WebCore/rendering/RenderGrid.cpp:2807
> +    // ASSERT(!m_grid.needsItemsPlacement());

Ditto.

Do you suggest to add another method? We can do it but it'd be redundant IMHO. I added this because it looks familiar (it's like needsLayout()).

ok

>> Source/WebCore/rendering/RenderGrid.cpp:2796
>> +    ASSERT(!m_grid.needsItemsPlacement());
>

Because all the callers of this function are executed during layout before clearing the grid. That's the key, we're sure we have completed the items placement and we're also sure that we're performing a layout.

>> Source/WebCore/rendering/RenderGrid.cpp:2807
>> +    // ASSERT(!m_grid.needsItemsPlacement());

In this case the ASSERT is not always true because we clear the grid after the layout. As the comment says, once the m_grid becomes persistent then the ASSERT will become valid.
