When underlying `net.Socket` instance is consumed in http server - no `data` events are emitted, and thus `socket.setTimeout` fires the callback even if the data is constantly flowing into the socket. Fix this by calling `socket._unrefTimer()` on every `onParserExecute` call. Fix: nodejs#5899

Gosh, timing issues on FreeBSD CI slave. One more try after the fix: https://ci.nodejs.org/job/node-test-pull-request/2327/ |
|
Quick question, does this apply to v4 as well? |
|
It does. |
|
Thank you! |

nit: wrap this in common.mustCall() ?
|
LGTM with a couple nits in the test. |

@indutny glad if I've helped & thank you for the fix :) |

This timeout value should probably be wrapped with common.platformTimeout()?
|
All fixed, new CI: https://ci.nodejs.org/job/node-test-pull-request/2345/ |

Landed in ec2822a, thank you! |

Looks like FreeBSD timing issues are back with this: #7643 I guess if there was some way to make this not dependent on a timer race, that would have happened, yeah? :-/ @nodejs/testing |

Actually, I think I've fixed it. PR coming soon... |
