esm: avoid try/catch when validating urls by anonrig · Pull Request #47541 · nodejs/node

anonrig · 2023-04-13T14:39:13Z

Due to URL.canParse, we can avoid try/catch block and have faster validation. The previous implementation was not performant due to:

Unnecessary string serialization - We don't need href, origin etc. for validating if a URL is valid or not.
URL.canParse can be written with V8 Fast API - enabling more performance out of this pull request.
URL.canParse does not return anything except a boolean.

Given that URL.canParse is user-mutable, should we use const { canParse } = URL or something like that? Or even better, can we import it primordial-style from ada directly?

@aduh95 I like where this is going, but I couldn't visualize it. Can you elaborate on how we can import it primordial-style? We can always do const { canParse } = internalBinding('url'); if that's what you are recommending?

aduh95 · 2023-04-13T15:30:53Z

Yes, I mean something that's available only internally and cannot be mutated at runtime. const { canParse } = internalBinding('url') is close enough, let's roll with this :)

This is way better/cleaner :-) but does it prevent backporting this commit, since older release lines may not have URL.canParse?

It might make it harder, due to conflicts, but I don't think it will block backporting any future changes to ESM.

oh sure, i just meant, should this PR have any "do not backport" labels, or link to the canParse PR as a prereq?

I'm not quite sure. @nodejs/releasers what do you recommend?

JakobJingleheimer

Sweet, thanks! I was just suggesting this change last night in Slack 😁

canParse was added in #47179, and there's no labels that says the backport is blocked, so no action should be necessary here I think. PRs are backported in the order they landed on Current release lines, precisely because it's often the case that a PR builds on top of another one.

2. URL.canParse can be written with V8 Fast API - enabling more performance out of this pull request.

I'm confused by this. The C++ API still says this:

node/src/node_url.cc

Lines 116 to 117 in 4afb25c

// TODO(@anonrig): Add V8 Fast API for CanParse method
voidBindingData::CanParse(const FunctionCallbackInfo<Value>& args) { 

Or did you actually mean this PR does not improve performance until the TODO is resolved?

anonrig · 2023-04-13T21:09:32Z

Or did you actually mean this PR does not improve performance until the TODO is resolved?

I was giving some context to this particular change. It is definitely faster than the current implementation. Additionally, @KhafraDev just opened a pull request for adding v8 fast API to canParse#47552

ljharb · 2023-04-13T21:20:50Z

@aduh95 perfect, thanks for clarifying and linking :-)

Would someone re-review this pull request? It's required due to force-push.

 } = require('internal/errors').codes;
 const { exitCodes: { kUnfinishedTopLevelAwait } } = internalBinding('errors');
 const { URL } = require('internal/url');
+const { canParse: urlCanParse } = internalBinding('url');


nit: this sounds a little Yoda-esque
Suggested change
const{canParse: urlCanParse}=internalBinding('url');
const{canParse: canParseURL}=internalBinding('url');

Not sure this is better, isURLString might be more suited. URLCanParse has the upside of being consistent with how primordials are named, which is nice imho

I want to change this to URLCanParse too but I'm too demotivated by having to run Node.js CI multiple times because of the flaky tests.
