Distinguish between non-distributed and distributed type parameters by ahejlsberg · Pull Request #64237 · microsoft/TypeScript

Anders Hejlsberg (ahejlsberg) · 2026-09-10T19:35:21Z

With this PR we distinguish between non-distributed and distributed type parameters in conditional types. Previously we didn't which could lead to constraint violations. In the example

type Issue<A, B extends A> =
  A extends unknown ?
    Show<A, B> :  // Error
    never;

type Show<T, U extends T> = [T, U] & {};

we previously didn't report a constraint violation on Show<A, B>. We now report a new error

Type 'B' does not satisfy the constraint 'A'.
  'B' is only assignable to the non-distributed 'A' and 'A' has been distributed here.

A type parameter is considered to be distributed when it is referenced within a conditional type that distributes that type parameter. Specfically, in a conditional type T extends XXX ? AAA : BBB, T is considered distributed within the types XXX, AAA, and BBB.

The distributed form of a type parameter is a subtype of the non-distributed form of that type parameter, and behaves accordingly. In the Issue<A, B extends A> type above, B is known to extend the non-distributed A, but that doesn't imply it extends the distributed A, which is a subtype of the non-distributed A. For example, the type Issue<0 | 1, 0> creates a union of Show<0, 0> and Show<1, 0>, the second of which violates the constraints declared in Show<T, U extends T>.

The language service now shows (distributed) when hovering over distributed type parameters:

This makes it easier to recognize when a type parameter is distributed.

Fixes #63708.

Copilot

🟡 Changes recommended

Type serialization can now panic on nil input, and the new hover behavior lacks language-service coverage.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

Distinguishes distributed type parameters during conditional-type checking to detect previously missed constraint violations.

Changes:

Tracks distributed and non-distributed type parameters separately.
Adds targeted diagnostics and compiler baselines.
Labels distributed parameters in hover information.

Anders Hejlsberg (@ahejlsberg) Here are the results of running the user tests with tsc comparing main and refs/pull/64237/merge:

There were infrastructure failures potentially unrelated to your change:

2 instances of "Package install failed"
1 instance of "Git clone failed"

Otherwise...

Everything looks good!

Jeez - I think we need to close the coverage gap between RWC and our own test suite. Probably worth adding tests for things like the Exact pattern here (both the original and a corrected one).

Mateusz Burzyński (Andarist) · 2026-09-11T17:58:14Z

To be fair, homomorphic mapped types distribute too and they suffer from the same issue today. I played a little bit with closing that gap here: fix-63708...Andarist:mapped-type-distribution

I'm not entirely sure if all the breaks in the above are correct though. With the version above this one errors when today it doesnt - but it does seem to me that a suspicious indexed access is allowed here today:

declare function f<T, U extends T>(y: { [P in keyof T]: U[P] }): {
  [P in keyof T]: U[P];
};

type AB = { a: 1 } | { b: 2 };
type A = { a: 1 };

const result = f<AB, A>({ b: 123 });
//    ^? { a: 1 } | { b: unknown; }

Anders Hejlsberg (@ahejlsberg) Here are the results of running the user tests with tsc comparing main and refs/pull/64237/merge:

There were infrastructure failures potentially unrelated to your change:

2 instances of "Package install failed"
1 instance of "Git clone failed"

Otherwise...

Everything looks good!

User tests are clean and top 1000 has three failing tests, two of which are correct new errors. That leaves the new errors in dokploy which I'm not having a fun time chasing down. It's a combination of Zod types and custom types in the project and they are by no means simple. If anyone has ideas I'd love to hear.

Daniel Rosenwasser (DanielRosenwasser) · 2026-09-11T21:41:23Z

Mateusz Burzyński (@Andarist) was chatting with Anders Hejlsberg (@ahejlsberg) about the implementation here, and one of the points that came up was the fact that getActualTypeVariable shouldn't always necessarily call getNonDistributedTypeParameter. Not sure if you can do without that in your branch.

Mateusz Burzyński (Andarist) · 2026-09-11T21:53:11Z

Daniel Rosenwasser (@DanielRosenwasser) I was skeptical at first of expanding the scope of getActualTypeVariable and went back and forth on it. But I concluded that the role of getActualTypeVariable is roughly to answer the question of:
"Which declared type variable is underneath the checker’s synthetic wrappers?"

And isn't this just a new kind of wrapper that has to be dereferenced? The problem at hand is specifically the reverse mapped type inference where the inference target is T[K] and not an ordinary type variable. And thar requires dereferencing (T distributed)[K] to T[K] so it could be recognized as a viable inference target etc. And reverse mapped types can also just recurse... so to account for that you also need a recursive "unwrap" and getActualTypeVariable plays its role well in that.

I experimented with the dokploy regression and at least some of that can be narrowed down to exactly that problem :p Just this time it's about T[K distributed]. You can see the isolated patch targeting this branch here with a test and just that getActualTypeVariable change: fix-63708...Andarist:TypeScript:fix-dokploy-reverse-mapped-inference

Of course, maybe there is a counterargument to all of that and a different solution to account for the reverse mapped types but that one seemed right to me at the time of preparing that experiment

Anders Hejlsberg (ahejlsberg) · 2026-09-12T00:05:41Z

Mateusz Burzyński (@Andarist) I went through and examined all the places we use getActualTypeVariable and it does indeed seem fine to have it only return non-distributed type parameters. And, certainly, it fixes the issue in dokploy without causing any other changes.

Anders Hejlsberg (ahejlsberg) · 2026-09-12T00:17:50Z

Mateusz Burzyński (@Andarist) Borrowed your regression test, thanks for researching.
