I see that ktor-client-ios has cancelation handler
https://github.com/ktorio/ktor/blob/master/ktor-client/ktor-client-ios/darwin/src/io/ktor/client/engine/ios/IosClientEngine.kt
Will it work with coroutine cancelation ?
I mean if we wrap it by

singleFromCoroutine

and on dispose it will be canceled ?

[Arkadii Ivanov]

It should work, but be careful with freezing. I suppose freezing the Disposable (and so Job) will eventually freeze Ktor things and it may crash. Also I think this can only work with mt coroutines and the new Reaktive nmtc version of the coroutines-interop module.

I use Reaktive nmtc and mt coroutines but dont receive cancelation =(
Probably I am missing something

[Arkadii Ivanov]

The coroutine itself should be cancelled. There are tests for this case, but you could check manualy as well. So if the corotuine is cancelled, then it is probably a question to Ktor.

What Reaktive essentially does is:

GlobalScope
        .launch(Dispatchers.Unconfined) {
            try {
                onSuccess(block())
            } catch (ignored: CancellationException) {
            } catch (e: Throwable) {
                onError(e)
            }
        }
        .asDisposable()

So it lounches a coroutine and uses its Job for cancellation.

[Arkadii Ivanov]

How do you expect to "receive cancellation"?

[Dmitry Motyl]

Sorry it was my fault
it works fine
and NSURLSession request canceled on dispose of subscription

@Arkadii Ivanov thank you for mt coroutines interop support😃
