LGTM. (As always, there's room for some more information to be added, but this is certainly better than not having it documented at all.)

Trott · 2017-06-11T18:32:25Z

I wonder if it might be possible to indicate a use case where a user might want to access these properties. Otherwise, readers may wonder about the statements that users usually won't want to access them.

mscdex · 2017-06-11T18:45:38Z

I think we should just document one of the two. At some point it'd be nice to remove one of them to have less duplication.

Since core itself uses .socket much more than .connection, I'd say we document .socket.

JustinBeckwith · 2017-06-11T19:35:48Z

That's a great point. I was mostly just trying to address #12617, but to be honest I am having trouble thinking of an example where accessing the raw socket is required or advisable. Followed up on the issue to learn more.

dismissing my review until mscdex suggestion sorted; I wouldn't stop anyone else from approving if they like this as-is, though

JustinBeckwith · 2017-06-12T01:41:59Z

I went ahead and added the same documentation for request.socket and request.connection, since their use is probably more common than the same properties on the response.

@mscdex I agree that having both of these isn't ideal. I did some searching, and mostly found folks using req.connection as opposed to req.socket, even in the express docs:

https://www.google.com/search?q=%22req.connection%22&oq=%22req.connection&aqs=chrome.0.69i59j0j69i57j0l3.3608j0j7&sourceid=chrome&ie=UTF-8

For now, I went ahead and documented both, with connection just linking out to socket. I'm happy to file a follow up issue to make the API breaking part of the change. Thoughts?

JustinBeckwith · 2017-06-12T01:43:02Z

Also, I added an example :)

Nit: I think the name (`connection`) is not needed here as this is property not a function argument.

I don't think we need to duplicate the type in a separate sentence if it is already specified above.

JustinBeckwith · 2017-06-12T15:55:14Z

Thanks for the awesome feedback folks. All addressed.

LGTM with a couple of tiny nits. Thanks!

Can you please wrap this line and the next one it at 80 characters?

silverwind · 2017-06-13T20:28:30Z

I think worthy cases to document would be req.connection.remoteAddress and req.connection.remotePort, which hold the remote adress and port, something which is useful for logging and access control.

JustinBeckwith · 2017-06-17T21:12:21Z

Addressed all the things and rebased into one commit!

Are these supposed to be directly after each other?

Sorry to nitpick, but "IP address" would be more correct, as IP is just the protocol. Also, I'd add a second print for the port. Same goes for the res example below.

One more try 😂

Thanks! Landed in d3d66a5.

I also took the liberty to change IP to IP address 😉

Argh, I forgot that we lint the docs.

I was able to force-push a fix as the commit was still on HEAD so this has now landed on 24ecc33.

Ugh. Per the collab guidelines: However, you are only allowed to force push to any Node.js branch within 10 minutes from your original push. If someone else pushes to the branch or the 10 minute period passes, consider the commit final.

This force push happened 2 hours later. Please do not do that as it causes quite a bit of hassle for other devs.

silverwind · 2017-06-19T18:35:15Z

Yes, I'm aware of that rule. Just thought it's easier to backport as one commit later. What real harm does it cause when the replaced commit is still on HEAD?

addaleax · 2017-06-19T18:59:09Z

What real harm does it cause when the replaced commit is still on HEAD?

@silverwind The question is not really where the commit is in the history; the problem is more that people who update their clones from upstream now have a bogus master after force-pushing. For example, I think new PRs based on that old master would appear to include the commits that were force-pushed out of the way.

jasnell · 2017-06-19T19:08:25Z

I have four local branches and one open PR branch that I had rebased off master when I started today that I ended up having to go back and correct after the force push. Forcing outside of the 10 minute window ends up meaning other collaborators end up having to do extra work they really shouldn't have to do.
