The logic looks good. The test is incorrectly named -- it should be buffer-data-array-buffer.html. A few specific comments.

While reviewing this, I realized there's a preexisting bug in associateBufferData(ArrayBufferView*). Let's commit this change and fix the other bug under https://bugs.webkit.org/show_bug.cgi?id=42124 , and refactor this code under the other bug.

While reviewing this I realized there's a preexisting bug in bufferData and bufferSubData taking ArrayBufferView. Let's check this code in as is to maintain parity between the implementations, and fix both under https://bugs.webkit.org/show_bug.cgi?id=42125 .

Changed the test name.

Also, add usage enum check (since the patch for checking this in other bufferData() entries has already landed).

Looks good to me. One additional comment.


WebCore/html/canvas/WebGLRenderingContext.cpp:379
 +          if (!validateBufferDataUsage(usage))
This needs to be done in all cases. It's inappropriate to do the associateBufferData call if the later bufferData call will fail because of an INVALID_ENUM error. This fix can be done in a subsequent bug for this entry point as well as the one taking ArrayBufferView*.
