src: use JS inheritance for AsyncWrap
#23094
Conversation
For all classes descending from `AsyncWrap`, use JS inheritance instead of manually adding methods to the individual classes. This allows cleanup of some code around transferring handles over IPC.

YES!!!

Maybe use ctor
for this name as well, for consistency?

Done!
Definitely a good idea, I think, but is this going to be semver-major? |
@jasnell If necessary, I would be okay with that, but could you explain why this is semver-major? It doesn’t touch public API or remove methods, it just moves them to a different position on the prototype chain (of internal objects). |
Largely defensive. It shouldn't be breaking but as we've seen many times, it pays to be careful. At the very least we need a citgm run to be sure |
I ran CITGM – there are a lot of failures because of #23122, but in the diff between the run here and the master run, I didn’t find anything that would point to issues with this PR. |
Hopefully ok then :) |
@jasnell I think this will require a backport PR for v10.x anyway … let’s run CITGM on that as well, that should give a much clearer picture. |

Still LGTM
New CI: https://ci.nodejs.org/job/node-test-pull-request/17517/ (This still needs to wait for a second approval, or two more days.) |
Re-run of node-test-commit-aix. |
Btw, @joyeecheung … just thinking out loud: The most natural way to do mirror the C++ multiple inheritance might be to create a second native JS class (e.g. That sounds semver-major to me, though, and I still have some native stream refactoring that I’d like to do, so maybe I’d keep that approach in mind and we could implement it late in the Node 11 release cycle? |
Isn't that kind of like (Or..maybe we should do it the other way around, why does |
Because it’s both a class that wraps a libuv handle, and is a stream at the same time – it does make sense to use multiple inheritance here… |
… and again, Windows: https://ci.nodejs.org/job/node-test-commit-windows-fanned/21229/ |
