 Description  « Hide

test-http-buffer-sanity.js is very slow and times-out on windows when run under the test-runner. However, if process.stdout.write(',') is replaced with print(',') the test runs quickly and does not timeout. We need to investigate why process.stdout.write is slow when redirected by the test-runner.

attaching test-runner patch that makes synchronous log writes async. This does not fix the issue, but should help.
