@nodejs/http The test I’m adding here is failing in some CI machines with:

    events.js:116
          throw er; // Unhandled 'error' event
          ^
    
    Error: read ECONNRESET
        at TCP.onread (net.js:625:25)

Could I ask you to take a look at the test? I’m pretty certain it’s not related to the code change here, but I’d be curious to know whether there’s anything obviously wrong with it…

I don't know if this would be considered an issue with the test... there's a race condition between the server being closed and the request being processed. Most of these http tests would put the server.close(); in an event listener for end rather than a callback. Not sure if this is expected behaviour or a bug though... I can see a case for both.

@apapirovski Okay, I think I got it right. I am surprised though, I wouldn’t think it’s possible for the req.end() callback to fire before the connection is actually established?

@addaleax Yeah, I honestly don't know... As far as I can tell, no one that knows the http module well is around and contributing anymore, and it's so convoluted and full of edge case handling that it's really, really hard to get a proper understanding of everything that's going on. I've considered doing some refactoring in the past but not sure where to start even...

With thanks to Anatoli Papirovski for providing helpful
tips when writing the test.
