Bug (refactor) – [WebGL] Vertex attribute binding validation method

• Component: WebGL
• Status: RESOLVED FIXED

[Przemyslaw Szymanski]

validateVertexAttributes method can has a little code refactoring. We can move some calculations to a separate methods.
This also can be usable in other parts of the code. So less code and easy to reuse now.

Second check should be enough here.

[Przemyslaw Szymanski]

I can't agreed. Two reasons:
1) I tested only the second check and it was not work well
2) Vertex attribute can be disabled (and then check should be true, it is ok) or enabled but bound. It can't be enabled and not bound.

So there must be two checks

sorry, I missed that you moved the enabled check too.

Do you need the second enabled? (if enabled is false, the second part of the condition does not get evaluated, while if enabled is true, then it doesnt bring much value to the second part of the condition)

Good point. Thank you. I updated this code. Review again please.

"by moving"

"to a separate"

"more readable and more clear": pretty much means the same. Probably one is enough.

> Source/WebCore/ChangeLog:13

There is no behavior change, right? If so, it is a good idea to say so in the Changelog.

> Source/WebCore/html/canvas/WebGLVertexArrayObjectOES.h:61
> +        inline bool isBound() const { return bufferBinding && bufferBinding->object(); }

inline is redundant here.

> Source/WebCore/html/canvas/WebGLVertexArrayObjectOES.h:62
> +        inline bool validateBinding() const { return !enabled || isBound(); }

Ditto.

Looks like a nice refactoring. r=me but please let Dean take a final look before landing as he was reviewing this as well.

[Przemyslaw Szymanski]

Dean Jackson, could you do a final review for this patch? Thank you.
