Per spec, accesses to a DataView object must throw a TypeError if the underlying ArrayBuffer has been detached/neutered. Since that implies a length of 0, we used to detect this as an out-of-bounds access and throw a RangeError. Adding a separate check for buffer detachedness lets us distinguish both cases properly. Bug: v8:4895 Cq-Include-Trybots: luci.v8.try:v8_linux_noi18n_rel_ng Change-Id: I1c1d4145dcd77dfb69f61062e14a6e8e538d45eb Reviewed-on: https://chromium-review.googlesource.com/947585 Reviewed-by: Adam Klein <adamk@chromium.org> Commit-Queue: Jakob Kummerow <jkummerow@chromium.org> Cr-Commit-Position: refs/heads/master@{#51712} |

This directory contains code for binding the test262 test suite into the v8 test harness. The tests are checked out as a dependency from https://chromium.googlesource.com/external/github.com/tc39/test262 at a revision specified in the DEPS file as 'data' in this directory. They are fetched with 'gclient sync'. To update to a newer version, please change the DEPS file. Using a newer version, e.g. 'deadbeef' may be possible but the tests are only known to pass (and indeed run) with the DEPS revision. Example: cd data git fetch git checkout deadbeef 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.
