cluster: remove handles when disconnecting worker #3677
Conversation

Looks like the CI had some issues with the test. |
|
Fix-ups applied. New run: https://ci.nodejs.org/job/node-test-pull-request/675/ |
|
LGTM, and I think the CI is ok. Looks like some Windows slaves went offline. |

There was a problem hiding this comment.
was going to suggest the same: https://code.google.com/p/v8/issues/detail?id=4518

Commit log is pretty shallow, may I ask you to add more information to it? |
|
Otherwise LGTM |

LGTM |
Due to the race window between the master's "disconnect" message and the worker's "handle received" message, connections sometimes got stuck in the pending handles queue when calling `worker.disconnect()` in the master process. The observable effect from the client's perspective was a TCP or HTTP connection that simply stalled. This commit fixes that by closing open handles in the master when the "disconnect" message is sent.

Tagged lts-watch-v4.x but can I suggest letting this brew in master / v5 for 10 days or so? |

+1. Not planning another LTS update round for at least another week

Any chance this to be ported to v0.12? |
|
Possibly. I put it on the watch list so it can be evaluated |
|
@bnoordhuis do you think it is ready to land in v4.x? |
|
@thealphanerd Maybe wait a little longer, it hasn't made its way into a release yet. It's scheduled for v5.1.0, see #3736 (comment). |
|
Yeah, likely best to hold off. Just in case. @bnoordhuis ... keep in mind that @thealphanerd was only talking about landing in |
|
indeed |
|
Oh, in that case go for it. |
