Try run with certain idna crate internals marked as inline(never):

(Rather concerningly, without this a local run on bloaty showed one of the deprecated idna methods compiling to huge code. Unclear why it wasn't LTOed away as unused locally. Hence, trying to make binary size comparisons on "shippable" try builds and not trusting my local config.)

I opened a draft PR on the idna crate: https://github.com/servo/rust-url/pull/923

Looks like the cookie permission UI needs a mode where an asterisk is allowed.

Looks like the cookie permission UI needs a mode where an asterisk is allowed.

No, the issue is the other way round. The cookie UI expects an asterisk is the host name to fail parsing, but WHATWG allows. We have two forbidden characters that WHATWG does not forbid: asterisk and double quote.

Perhaps I'm going to have to allow customizable ASCII deny lists in the idna crate. :-(

Hacking around this for now.

[Henri Sivonen (:hsivonen) (not reading bugmail until 2025-02-06)]

Sigh. More places where existing code expects IPv6 addresses to make it through ToASCII without error.

If I'm reading this correctly, this isn't enough to visibly move the Speedometer3 needle. (It would have been surprising for host parsing to make a notable difference alone.)

As for microbenchmarking pathless nsStandardURL creation:
https://treeherder.mozilla.org/perfherder/compare?originalProject=mozilla-central&originalRevision=c560ac2dab5f138b9d9fc117124a8edd04dc0d3f&newProject=try&newRevision=a3d860464cc6120f4db21a6b5ae01083020f9677&framework=6&page=1&filter=TestIDNA+BenchUrl

Leading digit ASCII becomes worse. Other cases become better. Plain ASCII in single digits. Various actual IDNA case have their execution time reduced by 55%...70%.

I think I'm not going to optimize the leading digit case at this time. It's pessimized in case there's subsequent bidi in the domain. Currently Gecko fails to account for this case.

Comment 18

[Henri Sivonen (:hsivonen) (not reading bugmail until 2025-02-06)]

Sigh. We have way too many places that pass IP addresses or even port numbers through places where the code says it's dealing with a host name. I'm changing these to at least reject ASCII characters that don't have a glyph, but I'm declaring rejecting colons and square brackets out of scope for this patch.

Improvements:

As there's an improvement, there's no need for an action.

An improvement makes sense, since this change removed unicode-normalization from the build, and it is known from outside-of-Gecko measurement that the icu_normalizer back end for the idna crate results in smaller binary size than the unicode-normalization back end.
