A large number of failures seem to be due to the signature of alert() changing in the output from TypeScript-DOM-lib-generator

Any idea what the failure looks like?

Err, okay, alert(number). Oh no.

There were interesting changes:

Besides ArrayBufferLike, it's almost all additions. Plus tonnes of comment changes.

Actually I'm talking about https://github.com/microsoft/TypeScript/actions/runs/14803024546/job/41565917783?pr=61647, but that's just an internal test?

See #61647 (comment). A large percentage of the DT tests failures are due to the signature of alert() changing.

~~I don't see any match of alert there, what am I missing?~~

Ah, the "is not assignable to parameter of type 'string'" errors. Err, still looks like something TS test specific, but perhaps also maybe an early smoke of something bigger. I'm open to backout.

There are similar errors in the user tests, though not as frequent.

Ron Buckton (@rbuckton) Here are the results of running the user tests with tsc comparing main and refs/pull/61647/merge:

There were infrastructure failures potentially unrelated to your change:

1 instance of "Timeout"

Otherwise...

Something interesting changed - please have a look.

TypeScript Bot (@typescript-bot): pack this

The bot is broken, I am fixing it. (your command also has a colon after the username which probably wouldn't work)

I have that as a "Saved Reply" on GitHub. It's always worked in the past.

Ron Buckton (rbuckton) · 2025-05-07T16:48:23Z

The errors in effect should be addressed by Effect-TS/effect#4834.

Ron Buckton (rbuckton) · 2025-05-07T20:55:23Z

I've also put a PR up for VSCode here: microsoft/vscode#248346

Jake Bailey (jakebailey) · 2025-05-07T21:58:14Z

Should we revert that alert PR first? (I am still working on fixing the bot to retest this ☹️)

Ron Buckton (rbuckton) · 2025-05-07T22:01:58Z

Should we revert that alert PR first? (I am still working on fixing the bot to retest this ☹️)

No, the revert we made here was also made to TypeScript-DOM-lib-generator: microsoft/TypeScript-DOM-lib-generator#2015

Ah, great; I just hadn't gotten that far into my inbox.
