Hey @DanielRosenwasser, I've packed this into an installable tgz. You can install it for testing by referencing it in your package.json like so:

{
    "devDependencies": {
        "typescript": "https://typescript.visualstudio.com/cf7ac146-d525-443c-b23c-0d58337efebc/_apis/build/builds/155637/artifacts?artifactName=tgz&fileId=04DE374095785839F62F13D7F462400B471B8FC647A291E41CD31D23BFD6186002&fileName=/typescript-5.2.0-insiders.20230626.tgz"
    }
}

and then running npm install.

There is also a playground for this build and an npm module you can use via "typescript": "npm:@typescript-deploys/[email protected]".;

jakebailey · 2023-06-26T17:23:12Z

@JoshuaKGoldberg Any chance you could throw the above package ("typescript": "npm:@typescript-deploys/[email protected]") into the ts-eslint CI to see if it passes again?

typescript-bot · 2023-06-26T17:40:51Z

@DanielRosenwasser Here are the results of running the user test suite comparing main and refs/pull/54781/merge:

There were infrastructure failures potentially unrelated to your change:

1 instance of "Unknown failure"
1 instance of "Package install failed"

Otherwise...

Something interesting changed - please have a look.

@typescript-bot cherry-pick this to release-5.1

typescript-bot · 2023-06-26T19:03:30Z

Heya @DanielRosenwasser, I've started to run the task to cherry-pick this into release-5.1 on this PR at 8d94382. You can monitor the build here.

typescript-bot · 2023-06-26T19:09:27Z

Hey @DanielRosenwasser, I've opened #54786 for you.

Component commits: 8d94382 Do not mark indexed access object type comparisons as unreliable.

typescript-bot · 2023-06-26T19:32:30Z

Hey @DanielRosenwasser, the results of running the DT tests are ready.
Everything looks the same!
You can check the log here.

typescript-bot · 2023-06-26T20:02:01Z

@DanielRosenwasser Here are the results of running the top-repos suite comparing main and refs/pull/54781/merge:

Everything looks good!

Definitely will need to revert this revert eventually, but we absolutely need to make some things more efficient first to compensate.

Can we add a non-strict @types/lodash usage to the extended test suite (as that's what this fixes), since the DT run won't cover it? It's just a new folder in https://github.com/microsoft/typescript-error-deltas/tree/main/userTests right?

I believe so, @jakebailey can help you there.
