Bug 111641 – Conformance Test 1.0.3 (Beta) function: bufferData undefined value failed.

• Component: WebGL
• Status: RESOLVED FIXED

[Jason Anderssen]

Base on the conformance test from kronos group : https://www.khronos.org/registry/webgl/sdk/tests/conformance/more/functions/bufferDataBadArgs.html, 
bufferData was not protecting against an undefined value being provided.

These may seem like nitpicking comments (and they are) but WebKit is especially strict about coding style. Sorry. You get used to it :) Make these easy fixes and the r+ is yours.

In this space you should try to describe the bug and change in a little more detail. e.g. "The WebGL specification requires that buffer data cannot be of zero length. This is a new test in the Khronos 1.0.3 WebGL test suite."

Also, you should reference the Khronos test here. Typically we require a test for every WebKit commit, but in this case it's ok because we are in the process of incorporating the Khronos tests into WebKit, so it will be there eventually.

Remove this line.

You should always try to explain what you did in the changelog. In this case it is really easy - just something like "Synthesize error and return if size was 0."

> Source/WebCore/html/canvas/WebGLRenderingContext.cpp:1115
> +        // undefined in WEBGL will parse in 0.

No need for this comment. Also, for future reference, WebKit coding style requires comments to start with a capital letter.

Looks good. I missed this in the first pass, but we could have simply changed the test above to if (size <= 0), but this is explicit for the undefined case so I guess it is ok.
