WebSocket layout tests are flaky on Chromium Win

[Peter Kasting]

The following layout test is flaky on Chromium Win, for the release bot on the WebKit builder (see http://test-results.appspot.com/dashboards/flakiness_dashboard.html#group=%40ToT%20-%20webkit.org&showExpectations=true&tests=http%2Ftests%2Fwebsocket%2Ftests%2Fhixie76%2Fhandshake-fail-by-no-connection-header.html ) and the bots on the downstream builder (see http://test-results.appspot.com/dashboards/flakiness_dashboard.html#group=%40DEPS%20-%20chromium.org&showExpectations=true&tests=http%2Ftests%2Fwebsocket%2Ftests%2Fhixie76%2Fhandshake-fail-by-no-connection-header.html ).

I don't know why sometimes the handshake doesn't fail; maybe one of you can get somewhere with this?

See e.g. http://test-results.appspot.com/dashboards/flakiness_dashboard.html#group=%40DEPS%20-%20chromium.org&tests=http%2Ftests%2Fwebsocket%2Ftests%2Fhybi%2Fhandshake-fail-by-no-upgrade-header.html%2Chttp%2Ftests%2Fwebsocket%2Ftests%2Fhybi%2Fmasked-frames.html&showExpectations=true

http/tests/websocket/tests/hybi/close.html is flaky too:
http://test-results.appspot.com/dashboards/flakiness_dashboard.html#showExpectations=true&tests=http%2Ftests%2Fwebsocket%2Ftests%2Fhybi%2Fclose.html

I'll add it to test_expectations.txt. See also 61767 for more flaky WebSocket tests.

I found a bug on Chromium side.
I'm preparing a change for this issue.

I landed Chromium change to fix a socket termination problem on Windows.
I believe this change will fix many WebSocket close related flaky tests.

Looking at http://test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=http%2Ftests%2Fwebsocket%2Ftests%2Fhybi%2Fclose.html%2Chttp%2Ftests%2Fwebsocket%2Ftests%2Fhybi%2Fhandshake-fail-by-no-upgrade-header.html%2Chttp%2Ftests%2Fwebsocket%2Ftests%2Fhybi%2Fmasked-frames.html%2Chttp%2Ftests%2Fwebsocket%2Ftests%2Fhixie76%2Fhandshake-fail-by-no-connection-header.html

I'm not seeing any failures since http://crrev.com/104852. If things stay green for another day, can you remove the failing expectations from test_expectations.txt?

Here's flakiness dashboard link for tests whose test expectation is being removed:

These tests stay green these days.
