Bug 229050 – [GTK][WPE] Test fast/canvas/webgl/shader-with-comma-op.html and fast/canvas/webgl/shader-with-struct-array.html fail since they were added

• Component: WebGL
• Status: RESOLVED FIXED

[Carlos Alberto Lopez Perez]

Test fast/canvas/webgl/shader-with-comma-op.html fails since it was added on r279656 on GTK and WPE.

The text failure is:

This two tests seems related to the Metal backend of WebGL. On Linux Metal is not supported.

I wonder if the output they give is expected and we should simply skip them or there is something to fix on the WebKit Linux/WebGL backend?

Expectations updated on r281002

[Kyle Piddington]

As a heads up, these tests were added to verify fixing the following two samples:
https://bugs.webkit.org/show_bug.cgi?id=226865
Shader-with-struct-array: https://zynaps.com/content/photon/


Shader with comma-op
https://bugs.webkit.org/show_bug.cgi?id=227723
https://jsfiddle.net/9p1f3t5r/2/

[Alejandro G. Castro]

After replacing the WebGL backend with ANGLE these tests are fixed. The gardening commit is:
