Bug 110887 – [chromium] Adapt test expectations to V8 __proto__ changes.

• Component: WebCore JavaScript
• Status: RESOLVED FIXED

1)  fast/dom/Window/window-custom-prototype.html [ Failure ]
2)  fast/js/JSON-parse.html [ Failure ]
3)  fast/js/cyclic-prototypes.html [ Failure ]

ad 1) This is expected bahavior, consistent with SpiderMonkey. The test
      expectation is broken. Assigning 'null' to '__proto__' makes the
      accessor installed on Object.prototype disappear.

ad 2) The result of JSON.parse() doesn't match the result we get when
      evaluating the same string through eval() as V8 still has special
      handling of the __proto__ property for object literals.

ad 3) Test fully matches the WebKit expectation now and no longer fails.
      Expectation specific to "chrome" platform should be removed.

Don't you need to update LayoutTests/platform/chromium/TestExpectations?

Has the V8 change been already landed? Or it is planned to be landed and you are trying to update these tests in advance?

Maybe you can remove this file, as the result is now platform-independent.

Marking r- for now due to the failing tests. I'd guess you need to update TestExpectations (maybe temporarily).

It's about a V8 change that has not yet made it into Chromium, but is gonna be rolled in with our roll today. This is the change: https://code.google.com/p/v8/source/detail?r=13728

Unfortunately the text is still different because of a different error message. So the text diff still fails. I adapted the description accordingly to state that.
