Client

CIO client bidirectional streaming

https://youtrack.jetbrains.com/issue/KTOR-2141

I'm working on a project which requires a client to stream a potentially large amount of binary data to a server and receive a stream in response. Because the client to server stream could be very long, I need to be able to read the response on the client side before the client has completed sending. From my testing, this does not appear to be possible using the CIO client.

Here is a small example which illustrates the limitation:

suspend fun main() {
    runServer()
    runClient()
}

suspend fun runServer() {
    embeddedServer(Netty, port = 8763) {
        routing {
            post("/post") {
                launch { readChannel("Server", call.receiveChannel()) }
                launch { call.respond(createContent("Server")) }
            }
        }
    }.also { it.start(false) }
}

suspend fun runClient() {
    HttpClient(CIO).request<HttpStatement> {
        url("http://localhost:8763/post")
        method = HttpMethod.Post
        body = createContent("Client")
    }.execute { readChannel("Client", it.receive()) }
}

fun createContent(name: String) = createContent {
    repeat(3) {
        println("$name: Sending ${BYTES.size} bytes")
        writeFully(BYTES)
        flush()
        delay(1000)
    }
}

fun createContent(body: suspend ByteWriteChannel.() -> Unit) =
    ChannelWriterContent(body, null)

suspend fun readChannel(name: String, channel: ByteReadChannel) {
    val buffer = ByteArray(BYTES.size)
    while (true) {
        try { channel.readFully(buffer) }
        catch(e: Exception) { break }
        println("$name: Read ${buffer.size} bytes")
    }
}

Running the above sample produces the following output:

Client: Sending 1024 bytes
Server: Read 1024 bytes
Server: Sending 1024 bytes
Client: Sending 1024 bytes
Server: Read 1024 bytes
Server: Sending 1024 bytes
Client: Sending 1024 bytes
Server: Read 1024 bytes
Server: Sending 1024 bytes
Client: Read 1024 bytes
Client: Read 1024 bytes
Client: Read 1024 bytes

As you can see, the client reads occur after all client sends which is not acceptable for my use case. Ideally, the output would look like this:

Client: Sending 1024 bytes
Server: Read 1024 bytes
Server: Sending 1024 bytes
Client: Read 1024 bytes
Client: Sending 1024 bytes
Server: Read 1024 bytes
Server: Sending 1024 bytes
Client: Read 1024 bytes
Client: Sending 1024 bytes
Server: Read 1024 bytes
Server: Sending 1024 bytes
Client: Read 1024 bytes

From what I can tell, it seems the HttpStatement.execute method blocks until the client has sent it's entire payload.

From what I understand, upon receiving a 401, Ktor is supposed to send a second request with the Authorization header. This is not happening. I have tried with expectSuccess = false and it still doesn't happen. It does work with sendWithoutRequest { true }.

Im trying to run the wizard project for KMP with Kotlin 1.5.30 on a M1 mac

I added this on my gradle

val iosTarget: (String, KotlinNativeTarget.() -> Unit) -> KotlinNativeTarget = when {
    System.getenv("SDK_NAME")?.startsWith("iphoneos") == true -> ::iosArm64
    System.getenv("NATIVE_ARCH")?.startsWith("arm") == true -> ::iosSimulatorArm64
    else -> ::iosX64
}

iosTarget("ios") {
    binaries {
        framework {
            baseName = "shared"
        }
    }
}

I could run the app on android and iOS, but then I added the Ktor dependencies and getting getting the following issue when I trying to run the app on an iOS simulator

Auth Feature: token refresh works only on main thread in Kotlin/Native

https://youtrack.jetbrains.com/issue/KTOR-3055

Ktor version:

Ktor client 1.6.2, default iOS engine

Description:

Auth feature uses global constants during token refresh process which are not marked with @ThreadLocal annotation. This makes it impossible to perform refresh from non-main thread in Kotlin/Native targets.

InvalidMutabilityException when using withContext and SavedHttpCall

https://youtrack.jetbrains.com/issue/KTOR-2033

Calling HttpResponse.readText is throwing this exception.
I'm using Dispatchers.Main only.
I'm not explicitly trying to save any HTTP calls, just making one-time calls.

I've tried both Ktor 1.5.1 and 1.5.0

as stated in documentation I want to create websocket in Server and connect to it from Android my code for Android:

     class MainActivity : AppCompatActivity() {
  override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val client = HttpClient {
    install(WebSockets)
}
lifecycleScope.launchWhenCreated {
    withContext(Dispatchers.IO) {
        client.ws(
                method = HttpMethod.Get,
                host = "ws://192.168.43.4",
                port = 23569, path = ""
        ) { // this: DefaultClientWebSocketSession

            // Send text frame.
            send("Hello, Text frame")

            // Send text frame.
            send(Frame.Text("Hello World"))

         

            // Receive frame.
            val frame = incoming.receive()
            when (frame) {
                is Frame.Text -> println(frame.readText())
                is Frame.Binary -> println(frame.readBytes())
            }
        }
    }
}

}
}

kotlin.native.concurrent.InvalidMutabilityException: mutation attempt of frozen <object>@72c18

I am trying to upload an image as multiform data using KMM

For android, it's working fine, and able to upload it. But in iOS, I can upload only text data not byteArray.

This is how I created HTTP client

expect fun httpClient(config: HttpClientConfig<*>.() -> Unit = {}): HttpClient

actual fun httpClient(config: HttpClientConfig<*>.() -> Unit) = HttpClient(Ios) {
    config(this)
    engine {
        configureRequest {
            setAllowsCellularAccess(true)
       }
    }
}

        autoFileData.value = fileData

        val arr = ByteArray(nsData.length.toInt()) { index -> data[index] }
        return arr
    }
}

Exception -> I haven't added throw to a function to get iOS crash

Exception doesn't match @Throws-specified class list and thus isn't propagated from Kotlin to Objective-C/Swift as NSError.
It is considered unexpected and unhandled instead. Program will be terminated.

CIO WebSockets client incorrectly sends Sec-WebSocket-Extensions header even if empty

https://youtrack.jetbrains.com/issue/KTOR-2388

I have observed that the CIO WebSockets client is sending out a Sec-WebSocket-Extensions header in the initial handshake even if no extension has been specified. This is causing issues with RFC 6455 compliant servers as (if my understanding is correct) the spec mandates that at least one extension be provided if the header exists (otherwise fail).

https://tools.ietf.org/html/rfc6455#section-9.1
https://tools.ietf.org/html/rfc2616#section-2.1 (ABNF notes)

I am not familiar enough with the Ktor code to submit a PR with a fix, but as a workaround a simple plugin can be used to strip the header from the request before sending it to the server:

import io.ktor.client.*
import io.ktor.client.features.*
import io.ktor.client.request.*
import io.ktor.http.*
import io.ktor.util.*

/**
 * Intercept outgoing HTTP requests to strip the `Sec-WebSocket-Extensions` header if it is empty.
 *
 * This feature should be installed after the `WebSockets` feature has been installed.
 */
internal class StripBlankSWSEHeader {
    private fun stripHeader(context: HttpRequestBuilder) {
        if (HttpHeaders.SecWebSocketExtensions in context.headers
                && context.headers[HttpHeaders.SecWebSocketExtensions]?.isBlank() == true) {
            context.headers.remove(HttpHeaders.SecWebSocketExtensions)
        }
    }

    class EmptyConfig

    internal companion object Feature : HttpClientFeature<EmptyConfig, StripBlankSWSEHeader> {
        override val key: AttributeKey<StripBlankSWSEHeader> = AttributeKey("StripEmptyWSExtensionHeader")

        override fun prepare(block: EmptyConfig.() -> Unit): StripBlankSWSEHeader {
            return StripBlankSWSEHeader()
        }

        override fun install(feature: StripBlankSWSEHeader, scope: HttpClient) {
            scope.requestPipeline.intercept(HttpRequestPipeline.Render) {
                feature.stripHeader(context)

                proceed()
            }
        }
    }
}

In the client configuration the StripBlankSWSEHeader feature must be registered AFTER the WebSockets feature:

install(WebSockets)
install(StripBlankSWSEHeader) // must be registered AFTER WebSockets feature
