deps: replace url parser with Ada #46410

anonrig · 2023-01-29T22:19:33Z

This work was done in collaboration with me, @miguelteixeiraa and @lemire. I would also like to thank @addaleax and @ronag for their help.

This pull request replaces the existing URL parser with Ada, a fast spec-compliant URL parser written from scratch using modern C++ focused on performance.

A little bit about Ada:

100% spec compliant (even has its own WPT updater, which led us to find a couple of errors in WPT)
Fully tested (using both web platform tests, custom tests not covered by WPT) on Big Endian Systems (s390x), Ubuntu 20.04, Ubuntu 22.04 (with G++ and Clang++), Windows VS 2022 (with and without ClangCL)
Well documented and available for the public at https://ada-url.github.io/ada
On typical URLs, we use between 50 and 60 instructors per input byte for fully parsing and validating a URL string into a URL data structure.

The possibilities with this pull request:

Soon: Dropping ICU as a dependency of Ada will allow Node.js releases that do not have ICU to parse URL hosts correctly.

Side Note: Current benchmarks show up to 87% faster URL parsing, with similar but sometimes faster execution speeds compared to url.parse.

Fixes #46332
Fixes #46063
Fixes #30334
Fixes #44476
Fixes nodejs/performance#33
Closes #41220

Something that I think should be experimented upon is to avoid copying all data back-and-forth every time a field is updated.

Maybe it might be better to fetch them from C++ every time they are accessed, or possibly use tricks to use the V8 fast API.

Deprecating url.parse

I think that has always been possible, with or without Ada? It's kept for compatibility reasons, not performance.

Removes the need to update and conform to URL WPT

We probably still want to run the JS tests to make sure that the JS glues work properly

You're right. This pull request does not remove them.

test/sequential/test-inspector.js test is failing. Appreciate any help in pinpointing why it causes timeouts. cc @targos @Trott @addaleax (according to git blame, you were the only ones who worked on this file in the last 3 years)

@anonrig it might very well be related to parsing the debugger websocket url

I see right now Ada has Windows-specific IDNA handling using IdnToAscii. I'm a little concerned about this, as it would introduce platform-dependent URL parsing results. I also doubt Windows's IdnToAscii implements UTS46 fully.

I see plans to switch to an internal implementation (ada-url/ada#89) which would alleviate my concern. Do note though, that there are (still) outstanding issues with UTS46 on the spec side (see whatwg/url#744).

(Context: I helped create the previous WHATWG URL parser, and also maintain https://github.com/jsdom/tr46.)

lemire · 2023-02-01T19:40:28Z

I see right now Ada has Windows-specific IDNA handling using IdnToAscii.

When ICU is unavailable and we are under Windows, then ada falls back on Windows functions. That is correct.

Wherever we are, if ICU is available, we rely on ICU.
