[falsandtru]

Hangs on 06e2537

Reproduction

1. checkout https://github.com/falsandtru/one-liner-stream/commit/7804f9125f1b5040f3a8c85b599dc57df125c578
2. checkout and build 06e2537
3. $ cd one-liner-stream
4. $ node ../TypeScript/built/local/tsc.js src/ts/*.ts typings/*.ts --module commonjs --noEmit

Node 0.12.7

@falsandtru can you please provide us with a simple tsconfig.json to compile your project? Ideally a more minimal reproduction of the issue would be better as well. Otherwise it's difficult for me to verify that this is indeed a problem with the TypeScript and figure out what could be causing it.

[falsandtru]

I do not use tsconfig.json to this project. I'll try to minimize. I want to make sure in advance, were you able to reproduce this hangs? Thanks.

[falsandtru]

Please compile this code.

run $ node built/local/tsc.js export.ts

// export.ts
export class ReadableLiner<T> {
  compose<U>(composer: (stream: ReadableLiner<T>|TransformLiner<T, T>) => TransformLiner<U, U>|PassThroughLiner<U>): TransformLiner<U, any>|PassThroughLiner<U>
  compose<U>(composer: (stream: ReadableLiner<T>|TransformLiner<T, T>) => TransformLiner<T, U>|PassThroughLiner<U>): TransformLiner<U, any>|PassThroughLiner<U>
  compose<U>(composer: (stream: ReadableLiner<T>|TransformLiner<T, U>) => TransformLiner<U, U>|PassThroughLiner<U>): TransformLiner<U, any>|PassThroughLiner<U>
  compose<U>(composer: (stream: ReadableLiner<T>|TransformLiner<T, T|U>) => TransformLiner<T|U, any>|PassThroughLiner<U>) {
    return composer(this);
  }
}

export class TransformLiner<T, U> {
  compose<U>(composer: (stream: ReadableLiner<T>|TransformLiner<T, T>) => TransformLiner<U, U>|PassThroughLiner<U>): TransformLiner<U, any>|PassThroughLiner<U>
  compose<U>(composer: (stream: ReadableLiner<T>|TransformLiner<T, T>) => TransformLiner<T, U>|PassThroughLiner<U>): TransformLiner<U, any>|PassThroughLiner<U>
  compose<U>(composer: (stream: ReadableLiner<T>|TransformLiner<T, U>) => TransformLiner<U, U>|PassThroughLiner<U>): TransformLiner<U, any>|PassThroughLiner<U>
  compose<U>(composer: (stream: ReadableLiner<T>|TransformLiner<T, T|U>) => TransformLiner<T|U, any>|PassThroughLiner<U>) {
    return composer(this);
  }
}

export class PassThroughLiner<T> {
  compose<U>(composer: (stream: ReadableLiner<T>|TransformLiner<T, T>) => TransformLiner<U, U>|PassThroughLiner<U>): TransformLiner<U, any>|PassThroughLiner<U>
  compose<U>(composer: (stream: ReadableLiner<T>|TransformLiner<T, T>) => TransformLiner<T, U>|PassThroughLiner<U>): TransformLiner<U, any>|PassThroughLiner<U>
  compose<U>(composer: (stream: ReadableLiner<T>|TransformLiner<T, U>) => TransformLiner<U, U>|PassThroughLiner<U>): TransformLiner<U, any>|PassThroughLiner<U>
  compose<U>(composer: (stream: ReadableLiner<T>|TransformLiner<T, T|U>) => TransformLiner<T|U, any>|PassThroughLiner<U>) {
    return composer(this);
  }
}

new ReadableLiner<number>()
  .compose(stream => stream);

More info:

Compile failed without error messages

My original code compile finished without errors after a few hours, but compiled code is empty(output the empty file when I specified --outFile option). TS compiler must be show the error in this case because compile is failed.

We're going to need to investigate; in the mean time, this will avoid the issue you're running into:

interface Liner<T> {
    compose<U>(composer: (stream: ReadableLiner<T> | TransformLiner<T, T>) => TransformLiner<U, U> | PassThroughLiner<U>): TransformLiner<U, any> | PassThroughLiner<U>
    compose<U>(composer: (stream: ReadableLiner<T> | TransformLiner<T, T>) => TransformLiner<T, U> | PassThroughLiner<U>): TransformLiner<U, any> | PassThroughLiner<U>
    compose<U>(composer: (stream: ReadableLiner<T> | TransformLiner<T, U>) => TransformLiner<U, U> | PassThroughLiner<U>): TransformLiner<U, any> | PassThroughLiner<U>
}

export class ReadableLiner<T> implements Liner<T> {
    compose<U>(composer: (stream: ReadableLiner<T> | TransformLiner<T, T | U>) => TransformLiner<T | U, any> | PassThroughLiner<U>) {
        return composer(this);
    }
}

export class TransformLiner<T, Z> implements Liner<T> {
    compose<U>(composer: (stream: ReadableLiner<T> | TransformLiner<T, T | U>) => TransformLiner<T | U, any> | PassThroughLiner<U>) {
        return composer(this);
    }
}

export class PassThroughLiner<T> implements Liner<T> {
    compose<U>(composer: (stream: ReadableLiner<T> | TransformLiner<T, T | U>) => TransformLiner<T | U, any> | PassThroughLiner<U>) {
        return composer(this);
    }
}

var x = new ReadableLiner().compose(stream => stream)

new ReadableLiner<number>()
    .compose(stream => stream);

I confirmed, thank you. Another question. Are you accepted the another bug about error messages? I must be open the new issue?
