This also refactors the way we set the length of an arrays' backing store to use the new elements accessor interface. The actual fix is in DictionaryElementsAccessor::SetLengthWithoutNormalize() where we first search for non-deletable elements according to ES5 section 15.4.5.2 specifications. Snippet from the specification: Attempting to set the length property of an Array object to a value that is numerically less than or equal to the largest numeric property name of an existing array indexed non-deletable property of the array will result in the length being set to a numeric value that is one greater than that largest numeric property name.

This directory contains code for binding the test262 test suite into the v8 test harness. To use the tests check out the test262 tests from http://hg.ecmascript.org/tests/test262 at revision 271 as 'data' in this directory. Using later version may be possible but the tests are only known to pass (and indeed run) with that revision. hg clone -r 271 http://hg.ecmascript.org/tests/test262 data If you do update to a newer revision you may have to change the test harness adapter code since it uses internal functionality from the harness that comes bundled with the tests. You will most likely also have to update the test expectation file.
