Can you give us more context and details about this? What tests are failing?

just a tracking bug for a blink TestExpectations line for layout tests which depend on --js-flags=--harmony-async-await

Once it ships, bug will be fixed

Thank you for providing more feedback. Adding requester "spqchan@chromium.org" for another review and adding "Needs-Review" label for tracking.

Just triaging this off the catchall Blink label. Async/await is a javascript feature.

Are there any remaining failures?

See the issue description, this is just tracking the TestExpectations that these tests are skipped when the feature is not enabled.

When the flag is enabled, the tests can be unskipped, the virtual test suite can probably be removed, and the "bug" will be fixed.

Skip virtual equivalent of async-callstack-async-await*.html layout tests.

Non-virtual async-callstack-async-await*.html tests have been disabled
in r409884, but the tests have been flakily running and timing out in
the virtual test suites:

- Site Isolation Win:
  https://build.chromium.org/p/chromium.fyi/builders/Site%20Isolation%20Win/builds/15853

- WebKit Mac10.11 (dbg):
  https://test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=virtual%2Fasyncawait%2Finspector%2Fsources%2Fdebugger-async%2Fasync-await%2Fasync-callstack-async-await2.html

Based, on the above, this CL is broadening the test expectations for
virtual/asyncawait/.../async-callstack-async-await[23].html so that:

- They cover non-Debug builds (since Site Isolation Win tests Release build)

- They cover all platforms (since these tests are also flaky on Mac10.11)

[DevTools] Masrk virtual/asyncawait/inspector as slow

Mark virtual/asyncawait/inspector/sources/debugger-async/ as SLOW.
I'll mark it as timeout if it won't help.

[DevTools] Better label for async function call stacks

Async call stack with async function always contains (async function) label and async function as top frame for following stack. We can merge label with this frame for better user experience.

Is this done?

Marking as fixed, as the flag is long-gone and no test expectations files reference this bug.
