lib: replace MessageEvent with undici's #52370

KhafraDev · 2024-04-04T15:52:25Z

undici's MessageEvent is better tested and has a complete WebIDL
implementation for validation. Not only this, but it's also used in
Node's current WebSocket implementation. There are a large number of
webidl-related issues in the current MessageEvent, such as not
implementing MessageEvent.prototype.initMessageEvent, not validating
arguments passed to its constructor
(#51771), not validating the values
passed to the constructor (such as not validating that ports is a
sequence, not converting origin to a USVString, etc.), and other issues.

lpinca · 2024-04-04T19:07:51Z

Have you considered the other way around? Fixing it in Node.js and reusing it in undici? Is it harder to port tests here?

KhafraDev · 2024-04-04T21:11:46Z

It is significantly harder to implement here without a real webidl implementation.

  });
  assert.throws(() => {
    new MessageEvent('message', { source: {} });
  }, {
-    code: 'ERR_INVALID_ARG_TYPE',
-    message: /The "init\.source" property must be an instance of MessagePort/,
+    name: 'TypeError',


Since we are changing error code this becomes a semver-major

@KhafraDev it would be better if this PR wouldn't be semver-major, so we can land it in v22.

I recall @addaleax did a lot of work optimizing Node's message event for workers, so pleasae run the MessageEvent benchmarks before landing this.

KhafraDev · 2024-04-06T15:26:19Z

MessageEvent should be compatible with the spec if it's marked as a compliant version of MessageEvent.

KhafraDev · 2024-04-26T00:32:52Z

I'd like to move this forward if possible, especially now that WebSocket is a global in node. I have no intention on supporting Node's current "MessageEvent" in WebSocket so it seems like we're in a standstill here.

I would be willing to expose a utility function to create an undici MessageEvent that skips webidl validations, which should yield the same performance as it is currently. Is that an acceptable solution here? Inevitably, as it is right now, undici cannot beat the current MessageEvent's performance, because node's MessageEvent does nothing correct, spec-wise.

KhafraDev · 2024-04-26T00:51:00Z

@benjamingr I experimented with this and I was able to make instantiating an undici MessageEvent over 3x faster than the current node one.

The only concern I have is that undici can be not always available, therefore blocking something else entirely.

benjamingr · 2024-04-26T15:31:48Z

I pinged @addaleax 3 weeks ago, that seems plenty of time to respond and worst case we can always revisit things.

responsiveness

benjamingr · 2024-04-26T15:34:26Z

For future reference @KhafraDev our process allows people to dismiss requests for feedback/changes after 7 days of unresponsiveness. I wanted Anna to be able to say her piece but that's not an excuse for me blocking a PR and neither was it my intention.

KhafraDev · 2024-04-26T15:43:09Z

You brought up a valid point and it'll lead to faster MessageEvent creation in node core and undici. I don't think that outright dismissing a valid review without further discussion would be a good idea, especially since I am not familiar with node workers.

benjamingr · 2024-04-26T17:07:39Z

@KhafraDev absolutely, feedback is important - that's why we wait a week (or more if people ask nicely and explain why) :) In this case it was not my intention to block the change just to try and get feedback.

I recall there is a good reason for the current design but it has been around 4-5 years since and we have tests and benchmarks. Anyway, just wanted to apologize and to make sure you know in the future you're free to dismiss these sort of reviews after a week of no response.

mcollina · 2024-04-27T20:34:59Z

@KhafraDev can you make this non-semver-major?

KhafraDev · 2024-04-28T05:13:09Z

I'll try

KhafraDev · 2024-04-29T05:31:04Z

I don't think it's viable. Errors are all handled uniformly in undici's webidl, so if we change the message in one place every other message will similarly get changed. It makes for much better, more consistent, errors, but doesn't give us much room to use custom messages.

I did add error codes for brand checks and I am gradually improving the existing errors, but I don't think we'll be able to match the current ones.
