Bug 177326 – test262: Hangs on Array tests length-exceeding-integer-limit-with-object.js and length-near-integer-limit.js

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: JavaScriptCore

[Joseph Pecoraro]

The test262 bot is seeing hangs on Debug bots running some tests:

> test262/test/built-ins/Array/prototype/reverse/length-exceeding-integer-limit-with-object.js
> test262/test/built-ins/Array/prototype/pop/length-near-integer-limit.js
> test262/test/built-ins/Array/prototype/push/length-near-integer-limit.js
> test262/test/built-ins/Array/prototype/unshift/length-near-integer-limit.js

This is causing a 20min timeout on the Debug test262 bots. For example:
https://build.webkit.org/builders/Apple%20El%20Capitan%20Debug%20Test262%20%28Tests%29/builds/3203

> test262/test/built-ins/Array/prototype/reverse/length-exceeding-integer-limit-with-
> test262/test/built-ins/Array/prototype/unshift/length-near-integer-limit.js

Actually just these two. The others error immediately and fail.

I'll skip these for now and use this bug to track the failures.

Skipped these tests in:

Leaving this bug open to track a fix.

ToLength called on values near/exceeding 2 ** 53 - 1 was aligned with the spec in r260990, fixing these tests.
