This broke between 2.0.1 and 2.0.2.

val websocketClient = HttpClient(CIO) {
    install(HttpTimeout) {
        connectTimeoutMillis = 2000L
    }
    install(WebSockets) {
        pingInterval = 30000L
    }
}

val session = websocketClient.webSocketSession("ws://some-url")

session.launch {
    while (isActive) {
        val frame = session.incoming.receive()
        // to things with frame
    }
}

The websocket server shows the client as connected and eventually reports an abnormal close. On the client side the coroutine is cancelled with a request timeout exception from ktor:

When I try to fetch html and analyze it in Multiplatform Mobile share lib, I got a crash in iOS, but work well in Android.

iOS error msg: IllegalArgumentException("List has more than one element.")

URL: https://mp.weixin.qq.com/s/UJipNKgGPzZ1iPJBAaLJXw

so I compile the ktor source code and debug inside, and then I foud out the reason is that the response header "content-type" has a repeated key-value entry，As shown below:

In this case, iOS native network lib will merge them into one key-value entry like {"content-type" : "text/html; charset=UTF-8 , text/html; charset=UTF-8" } .

But on the other hand, ContentType.parse() will parse "content-type" header and get two HeaderValue, after that it invoke Colloection.single() to check the result, then a IllegalArgumentException("List has more than one element.") will be throw.

I checked the implementation of other platforms，browserjs have the same issue.

I'm using the Ktor Client Auth feature with bearer tokens. But the refresh token is failing when a 302 redirect is involved.

My issue is as follow:

-I have an invalid token, let's call this token A

-I issue a GET /news/latest request with the invalid token A

-The backend replies with a 401 and the WWW-Authenticate header

-My refreshTokens block is executed and I get a new valid token, let's call this token B

-Ktor retries the previous GET /news/latest with the new token B

-Now the issue is that the backend replies with a redirect 302 /news/123

-Ktor follows the redirect and emits a GET /news/123 but this call is sent with the invalid token A

Everything is working correctly if there is no 302 redirect. Should I be doing something different for this use case to work?

I'm trying to connect to a server using a websocket, but I run into the following error: "SunCertPathBuilderException: unable to find valid certification path to requested target". I've tested the connection ("wss://acme.com/connect") with Postman and with PieSocket where everything seems to be working.

I'm using the following code:

val client = HttpClient {
    install(WebSockets)
}
runBlocking {
    client.wss(
        host = "acme.com"
    ) {
        val messageOutputRoutine = launch {
            try {
                for (message in incoming) {
                    message as? Frame.Text ?: continue
                    println(message.readText())
                }
            } catch (e: Exception) {
                println("Error while receiving: " + e.localizedMessage)
            }
        }

        // Wait for completion; either "exit" or error.
        messageOutputRoutine.join()
    }
}
client.close()

Thanks in advance!

When Ktor creates a java.net.http.HttpRequest it uses HttpTimeout.socketTimeoutMillis to set HttpRequest.timeout. But in java docs it's clear that HttpRequest.timeout sets timeout for whole request, not for time without any data in a socket, so it's better to use HttpTimeout.requestTimeoutMillis for that.

Place in ktor code where ktor sets HttpRequest.timeout

The link in the screenshot (https://ktor.io/docs/old/testing.html#map) attached goes to the following url which is a 404

According to the documentation the JmxReporter should be included in the metrics-jmx dependency, but that doesn't appear to be the case in version 1.6.8. I had to manually add the dependency to "io.dropwizard.metrics:metrics-jmx:4.2.9" instead.

however I can't find a place where JobCancellationException might have been caught and wrapped in another exception.
Route that is logging this is not doing anything in parallel.
This is only happening on ktor 1.3.4, never seen on earlier versions.

To share more models between client and server, it would be awesome, if ktor server and client could support ReadChannelContent on receiving data. Right now I use custom plugins for that:

// for server
val ByteReadChannelToReadChannelContent = createRouteScopedPlugin("ByteReadChannelToReadChannelContent") {
    onCallReceive { call ->
        val requestedType = call.receiveType

        if (requestedType.type != OutgoingContent.ReadChannelContent::class) return@onCallReceive

        transformBody { body ->
            object : OutgoingContent.ReadChannelContent() {
                override fun readFrom() = body
                override val contentLength = call.request.contentLength()
                override val contentType = call.request.contentType()
            }
        }
    }
}
// for client
object ByteReadChannelToReadChannelContent : HttpClientPlugin<Unit, Unit> {
    override val key: AttributeKey<Unit> = AttributeKey("ByteReadChannelToReadChannelContent")

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

    override fun install(plugin: Unit, scope: HttpClient) {
        scope.responsePipeline.intercept(HttpResponsePipeline.Transform) { (info, body) ->
            if (body !is ByteReadChannel || info.type != OutgoingContent.ReadChannelContent::class) return@intercept

            proceedWith(HttpResponseContainer(info,
                object : OutgoingContent.ReadChannelContent() {
                    override fun readFrom(): ByteReadChannel = body
                    override val contentType = context.response.contentType()
                    override val contentLength = context.response.contentLength()
                }
            ))
        }
    }
}

Ive seen alot of fixed issues about module system support in ktor, but right out of the box using the client-cio there are errors being thrown about split packages between both 'ktor.client.cio.jvm' and 'ktor.client.core.jvm' due to package 'io.ktor.client.plugins.websocket' in Java 17. Im using Gradle and the dependency: 'io.ktor:ktor-client-cio:2.0.0-beta-1'. Thanks!

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.

Hello!

I'm using Ktor in a KMM app, and I am not having any kind of problem in Android, but in iOS it behaves weird. I don't have the HttpCookies plugin installed, because I'm handling and storing the session cookie outside of Ktor.

What happens is that the very first request that is sent to the server (GET /api/session) contains a Set-Cookie header in the response, and for this request I don't save the cookie nor do anything with it, the request serves only to check if there is a session based solely on the response of the server. Both in Android and iOS we get the Set-Cookie header for this request.

The second request (POST /api/session) is made after the user attempts to log in using their credentials. For this request, we need the response to contain the Set-Cookie header so we can store the session token it contains and then pass it onto further requests. This happens in Android, but not in iOS. I tried removing the first request, and magically, I get a cookie for this one!

Is the iOS backend automatically storing and passing the cookie without my knowledge or consent? As I said before, I didn't install the HttpCookies plugin.

Ktor client appears to automatically add ; charset=UTF-8 to text-based content type requests, for example even if you set the Content-Type explicity to (say) application/json the Ktor client appends `; charset=UTF-8'.

Unfortunately some existing APIs check explicity for Content-Type=application/json to determine if the request is a valid content type. An example of this (arguably naive) behaviour is the UK-based Esendex SMS REST API, see https://developers.esendex.com/api-reference#messagedispatcher which responds with 400 Bad request; message: Unable to process request body

I'm not familar with the Ktor code base, but a quick search reveals the code which adds the ; charset=UTF-8 may be in ApplicationResponseFunctions, or maybe its request equivalent?

/**
 * Creates a default [ContentType] based on the given [contentType] and current call
 *
 * If [contentType] is null, it tries to fetch already set response header "Content-Type". If the header is not available
 * `text/plain` is used. If [contentType] is specified, it uses it
 *
 * Additionally, if charset is not set for either content type, it appends `; charset=UTF-8` to the content type.
 */
public fun ApplicationCall.defaultTextContentType(contentType: ContentType?): ContentType {
    val result = when (contentType) {
        null -> {
            val headersContentType = response.headers[HttpHeaders.ContentType]
            headersContentType?.let {
                try {
                    ContentType.parse(headersContentType)
                } catch (_: BadContentTypeFormatException) {
                    null
                }
            } ?: ContentType.Text.Plain
        }
        else -> contentType
    }

    return if (result.charset() == null) {
        result.withCharset(Charsets.UTF_8)
    } else {
        result
    }
}

I'm mapping a common Exception format in our app, but currently there is no way to get the request in the handleResponseException method. We just have access to the exception.

This limits my ability to pass information back about the exception completely. When I get a crash report on iOS or even on Android sometimes, I'm left with no information about where this crash is coming from (as it's an asyncronous request, and the caller isn't in the callstack). If I had the ability to at least include information about what request is failing, I could track down everywhere this is being used and better find the crash. As it is now, I've got almost no information to go off of.

If the path of the cookie starts with /, but the path of the requestURL does not, AcceptAllCookiesStorage does not find the cookie in its container (cookie list).

See attached test and debugger state.

I have a Netty server with installed WebSockets with pingInterval. After each delay it received PONG message.

Also, I have HttpClient with installed WebSockets on Kotlin/JS side with pingInterval set. But I don't catch any PING messages on server.

How it can be fixed?

To reproduce: run ./gradlew :native-test:nativeTest in the tests directory.

Would be nice to have an update soon for runTest support.

When logging response from. Ktor-client Logging feature with the help of ResponseObserver, the log does not contains the MDC context.
This mean when tracking all logs bound to an MDC context, response content log remains untracked.

This test illustrates the mentioned scenario :

in package [jvmTest]io.ktor.client.features.logging, in file LoggingTest.kt

@Test
    fun loggingWithMDCContextTest(): Unit = runBlocking {
        val messages: MutableList<String> = mutableListOf()
        val testLogger: Logger = object : Logger by LoggerFactory.getLogger("ktor.test") {
            override fun trace(message: String?) = add("TRACE: $message")
            override fun debug(message: String?) = add("DEBUG: $message")
            override fun info(message: String?) = add("INFO: $message")

            private fun add(message: String?) {
                if (message != null) {
                    val mdcText = MDC.getCopyOfContextMap()?.let { mdc ->
                        if (mdc.isNotEmpty()) {
                            mdc.entries.sortedBy { it.key }
                                .joinToString(prefix = " [", postfix = "]") { "${it.key}=${it.value}" }
                        } else {
                            ""
                        }
                    } ?: ""

                    messages.add(message + mdcText)
                }
            }
        }

        val localTestLogger: io.ktor.client.features.logging.Logger = object : io.ktor.client.features.logging.Logger  {
            override fun log(message: String) {
                testLogger.info(message)
            }
        }

        val client: HttpClient =  HttpClient {
            install(Logging) {
                level = LogLevel.ALL
                logger = localTestLogger
                // responseCoroutineContext = MDCContext()  This is to provide CoroutineContext from feature config
            }
        }

        MDC.put("trace_id", "48b49e15-f7c4-4991-9e33-23850a218718")

        val response: String = withContext(MDCContext()) {
            client.get("https://jsonplaceholder.typicode.com/todos/1")
        }

        MDC.clear()

        assertNotNull(messages)

        assertNotNull(response)
    }

Theory : First I suspected that this is because of EmptyCoroutineContext being used in launch, but when I gave MDCContext() from kotlinx-coroutines-slf4j to it, it still didn't work. Now I suspect, it is because function is provided as a predicate. However, I am not too sure about it. Can you help please ?

Change I tested :

scope.launch(feature.coroutineContext) {
    try {
        feature.responseHandler(sideCall.response)
    } catch (_: Throwable) {
    }

    val content = sideCall.response.content
    if (!content.isClosedForRead) {
        content.discard()
    }
}

where ResponseObserver = public class ResponseObserver(private val responseHandler: ResponseHandler, private val coroutineContext: CoroutineContext = EmptyCoroutineContext)

I am using ktor client v2.0.0-beta1,

I call the API that I called '/me' with the invalid token, then refresh token API as I excepted is called, and it failed because of our server logic,

 my expected behavior is to get the error on my first API('/me') because refreshtoken API is failed. but nothing has happened. even I haven't got the exception anywhere.

If a web server responds to HEAD request with Content-encode: gzip header, ktor client fails with the following exception:

Unexpected exception occurred during switching: kotlinx.coroutines.channels.ClosedReceiveChannelException: Unexpected EOF: expected 10 more bytes

Receiving byte array data by GET request with using ktor-client-curl on native (macosX64) seems to be leaking memory, here's the snippet used to reproduce:

    repeat(1000) {
        runBlocking {
                client.get("http://some-test-image.jpg")
                val responseBody: ByteArray = httpResponse.receive()
        }
    }

Running that code shows constantly increasing memory usage of the process - using quite big images seems to be quickest way to observe it. This seems to be reproducible with 1.5.3, 1.6.0, 1.6.7 as well as with 2.0.0-beta-1 (with introduced API changes into snippet). I actually cherry-picked these versions amongst others and each seems to be affected.

Is there anything I'm assuming wrong here? I would expect heap size to stabilise around some usage instead.

I have java.net.SocketException: Software caused connection abort on Android in a following scenario:

1. Start streaming with client.get<HttpStatement>(url).execute {.
2. Disable Internet on device - this breaks the streaming.
3. This exception appears (which is expected at this point).
4. Enable Internet back.
5. Any consecutive call with the same HttpClient also throws this exception immediately.

The only solution to this I found so far is creating a new HttpClient for every call.

Might be related to: https://youtrack.jetbrains.com/issue/KTOR-870

The whole snippet that causes it:

        var hashingSink: HashingSink? = null
        var writeSink: BufferedSink? = null
        try {
            hashingSink = HashingSink.md5(destinationFile.sink())
            writeSink = hashingSink.buffer()
            httpClient.get<HttpStatement>(url = Url(urlPath)).execute { response: HttpResponse ->
                var offset = 0
                val channel = response.receive<ByteReadChannel>()
                val contentLen = response.contentLength()?.toInt() ?: 0
                val byteBufferSize = 1024 * 100
                val buffer = ByteArray(byteBufferSize)
                do {
                    val currentRead = channel.readAvailable(buffer, 0, byteBufferSize)
                    if (currentRead <= 0) break
                    writeSink.write(buffer, 0, currentRead)
                    val progress = if (contentLen == 0) 0 else (offset / contentLen.toFloat()) * 100
                    emit(progress)
                    offset += currentRead
                } while (!channel.isClosedForRead)
                writeSink.close()
            }
            val downloadChecksum = hashingSink.hash.hex()
            if (downloadChecksum != checksum) throw ChecksumException(downloadChecksum, checksum)
        } finally {
            writeSink?.close()
            hashingSink?.close()
        }
       

So if I disable Internet on the device and get SocketException, the httpClient becomes unusable - every request I try to make ends up throwing the same exception.

Hello, guys! It seems setting defaultRequest.url.protocol on the client side breaks the ability to establish a ws connection. Please, check it out.

If I set defaultRequest.url.protocol, the client tries to establish a ws connection via http GET and fails.

But if I just comment off that setting, everything works.

Right now the FormBuilder and MultiPartFormDataContent support only one streaming primitive Input that is synchronous. This prevents streaming data in environments like JS because it's not viable to block the only thread for reading.

The suggested solution is to implement reading from the ByteReadChannel.

The following test fails using 2.0.0-beta-1 because the content-type header is removed from the request:

 @Test
    fun contentTypeTest() {
        val mockEngine = MockEngine { request ->
            if (request.headers.contains(HttpHeaders.ContentType)) respondOk() else fail("Expected content type header")
        }
        val client = HttpClient(mockEngine) {
            install(ContentNegotiation) {
                jackson {  }
            }
        }
        runBlocking {
            client.put("https://example.com/foo") {
                contentType(ContentType.Application.Json)
                setBody(mapOf("foo" to "bar"))
            }
        }
    }

The content-type should not be removed (or changed when explicitly set in the request)

My Ktor JS client is not receiving proper headers in browser target, despite it being working in nodejs target.

I reproduced the issue using a simple Ktor server:

data class UserSession(val id: String, val count: Int)

fun main() {
    embeddedServer(Jetty, port = 9000, host = "0.0.0.0") {
        install(CORS) {
            anyHost()
        }
        install(Sessions) {
            cookie<UserSession>("user_session")
        }
        
       routing {
            post("/login") {
                val name = call.receive(String::class)
                call.sessions.set(UserSession(id = name, count = 0))
                call.respond(HttpStatusCode.NoContent)
            }
            get("/session") {
                val userSession = call.sessions.get<UserSession>() ?: error("no session")
                call.respond(userSession.id)
            }
        }
    }.start(wait = true)
}

On the client side, my client build.gradle.kts looks like:

kotlin {
    jvm()
    js(IR) {
        browser()
        nodejs()
    }
    // ...
}

Consider this test:

@Test
fun shouldLogin() = runTest {
    val client = HttpClient(Js) {
        install(HttpCookies)
        install(Logging)
    }

    val name = "test"
    client.post<String>("http://0.0.0.0:9000/login") { body = name }

    val username = client.get<String>("http://0.0.0.0:9000/session")
    assertEquals(name, username)
}

I observed the following:

It looks like common headers are absent, especially the crucial cookie related ones.

I do not know if it is a bug, or if I misconfigured something, any idea?

EDIT: I changed the issue from Multiplatform, to JS only as this is reproducible even using only the JS engine in two different targets.

I'm setting defaultRequest like this on my client factory:

defaultRequest {
    url {
        protocol = URLProtocol.HTTPS
        host = "myapi.com"
        encodedPath = "apiPath$encodedPath"
    }
}

And I have an endpoint which sends request to a different host like this

suspend fun HttpClient.getOther(): Other = get("https://example.com/other")

I expect ktor to send request to https://example.com/other

I've tried to use different methods like:

suspend fun HttpClient.getOther(): Other = get {
    url {
        host = "example.com"
        path("other")
    }
}

suspend fun HttpClient.getOther(): Other = get {
    host = "example.com"
    url {
        path("other")
    }
}

All of them sent the request to https://myapi.com/apiPath/other instead

This may be expected behavior given the major version bump but wanted to document it and ask for guidance.

We have a dependency on ktor-io in the AWS SDK for Kotlin and are getting reports that having ktor-server-*:2.0.0-beta1 in the dependency set results in runtime errors:

Exception in thread "main" java.lang.NoSuchMethodError: 'void io.ktor.utils.io.bits.Memory.copyTo-iAfECsU(java.nio.ByteBuffer, java.nio.ByteBuffer, long, long, long)'

Gradle is resolving the SDK dependency to latest version (+--- io.ktor:ktor-io:1.6.3 -> 2.0.0-beta-1) and this is causing runtime issues. You can find the original issue here.

A dump of the class files shows the method renamed:

I thought maybe the inline value class usage and compiler version may be the culprit. I tried upgrading our library to compile with Kotlin 1.6.10 and recompiling and seem to see the same issue though. Is there any workaround here that doesn't involve upgrading to ktor-2.x? We will likely eventually upgrade but my concern is this will bifurcate users of our library such that it works only if you are on the same ktor version as the library.

Using the new memory model with versions:

kotlinVersion=1.6.0
coroutinesVersion=1.5.1-new-mm-dev2
ktorVersion=1.6.2-native-mm-eap-196

Produces the following error when referencing ktor-network:

MRE project attached, changing the number of threads in newFixedThreadPoolContext stops the error from happening, alternatively changing the delay from 500 to 100ms

Looks like a concurrency issue, it might be the expected behaviour however it's not documented anywhere I found/the error message isn't very descriptive, and it would also break in the default example in the docs

Related to https://youtrack.jetbrains.com/issue/KTOR-710 which is apparently not a kotlin-io bug https://github.com/Kotlin/kotlinx-io/issues/43
Possible duplicate of https://youtrack.jetbrains.com/issue/KTOR-3025

It is stable with Kotlin 1.6.0

Please backport the fix for KTOR-1824 "Client Certificate Authentication" to Ktor v1.x.
It is the only thing preventing my team from considering the use of Ktor in our new server applications.

Thank you.

May be it's a good time to remove headerSizeHint in 2.0, as it not used at all?

Newer versions of coroutines don't seem to have the SingleThreadDispatcher class which is used by ktor.

Updating coroutines to 1.6.0 breaks the build, see the following error

Module "io.ktor:ktor-network (io.ktor:ktor-network-iosx64)" has a reference to symbol kotlinx.coroutines/SingleThreadDispatcher|null[0]. Neither the module itself nor its dependencies contain such declaration.

This could happen if the required dependency is missing in the project.

Ktor currently uses BEST_COMPRESSION for java.util.zip.Deflater when the feature Compression is enabled. It should use DEFAULT_COMPRESSION rather than BEST_COMPRESSION.

BEST_COMPRESSION is generally many times slower than DEFAULT_COMPRESSION for miniscule improvements to compressed size, making BEST_COMPRESSION almost always the wrong choice when compression time is part of the equation.

Fixing this would probably also partially fix KTOR-1341 (compression is still expensive, but significantly less so).

Ideally compression level should be configurable, since the optimal choice depends on expected network speed, CPU speed, and which implementation the JDK uses, but DEFAULT_COMPRESSION is a pretty good default.

For me every completion list for every member access contains preventFreeze() and makeShared only because one of my dependencies (not me) uses ktor. I ofter use a completion list for observing members and seeing these two function every time is quite annoying. I personally think that having such extension functions on primitive type is a pretty bad practice since it pollutes everyone. If you have such dangerous API that shouldn't be normally used, probably it's better to define them as global functions without receiver.

To be honest, I would be very interested to know the reasoning behind the decision about making such functions, since if every kotlin library would add two extension functions to Any it would be probably nightmare. Also I'm wondering is any chance that these two functions would be removed from the completion list of every member access in future updates?

Hi Team!

Within your class: io.ktor.http.URLBuilder.kt you changed the signiture of Url from

public data class Url

To

public data class Url internal constructor

Which prevents the usage for us. We are using it like:

private fun sanitize(url: Url): Url {
    return Url(
        protocol = url.protocol,
        host = url.host,
        specifiedPort = url.specifiedPort,
        encodedPath = url.encodedPath,
        parameters = sanitizeParameters(url.parameters),
        fragment = url.fragment,
        user = url.user,
        password = url.password,
        trailingQuery = url.trailingQuery,
    )
}

Can you provide a fixed version e.g. 1.6.7 ? This would be the best for all customers of your library.

or provide a fix. I guess it should work somehow with the URLBuilder, but the new ParameterBuilder makes the compiler unhappy.

There should be a documentation about how to configure libcurl on Windows using minGW and Cygwin to be able to use ktor-client-curl engine.
The issue KTOR-3989 if resolved should be documented too.
Also, some information about troubleshooting common problems would be helpful.

https://ktor.io/docs/eap/gradle.html
KTOR-3673

Recently PR for #KTOR-325  has been pushed, and I'd like to have a test or an example in documentation how to use this new API as changing the contentType is what I'd like to have in my project (currently in my version (I had to copy the whole file into my project) it receives baseContentType with a restriction to match ContentType.MultipartAny without any parameters.

As evident from this slack thread, ktor-client docs for native desktop platforms are misleading. The docs should be explicit that they are referring only to desktop apps built with kotlin native. Additionally, it might also be worthwhile to review the language for jvm platform to indicate that client engines there can be used for jvm desktop apps as well, not just servers.

This also leads to false-positive issues like KTOR-3794

This might seem a bit of a petty issue to raise, but I've noticed that in the documentation, code snippets, and Gradle generated files, Prometheus is misspelled as Prometeus.

implementation("io.micrometer:micrometer-registry-prometheus:$prometeus_version")

Despite it being spelled as "prometheus" right next to it.

Annoying, but really annoying for some people.

Again, I appreciate it's a little petty, but help a guy with OCD out? :)

(Changes proposed initially in the kotlin-hands-on repository, since the tutorial is now moved to https://ktor.io/docs/creating-http-apis.html, linking it here):

The section about how to create a mutable list and where it should be in the code was a little bit confusing
Changing the return HttpStatusCode of Post route to store customer. In that this, case it's more common to use 201 (Created) instead of 202 (Accepted)

https://github.com/kotlin-hands-on/hands-on/pull/120

https://ktor.io/docs/eap/gradle.html

Right now documentation samples (here and here) don't mention authentication and encryption configuration of sessions which may result in insecure implementation if user doesn't already know importance of it and won't configure it on their own.

Unsigned/unencrlypted sessions are very insecure and some users may not be aware of it.

Also documentation and samples should not provide a sample of a key, and if a sample given then it should be blacklisted, so users won't be able to copy paste code snippet from documentation and reuse it, making the implementation insecure.

We are getting more users and generator gets higher RPS rate which leads to memory usage growth.
We need to consider caching all internal requests to fit into our memory limits.

From IDE it looks like after clicking migrate button, nothing happens and a failure message appears with a Try again button

Currently, the javadoc/dokka output is not published as a maven artifact.

The javadoc jar published to maven central looks like this:

ktor-server-core-1.6.7-javadoc/
└── META-INF
    └── MANIFEST.MF

1 directory, 1 file

It would be great it you could publish the output of dokka to maven, rather than just to the api.ktor.io site.

Kotlin 1.6.0 uses JVM target 8 by default, and Ktor dropped support for JVM target 6 and 7. If you want to use JDK 11 for all! modules, the Kotlin compiler cannot inline jvm 8 target binary code into jvm 11 byte code.
So there is no need to define JVM target 8 explicit in 1 module.

=> Remove JVM target 8 in metrics micrometer

If you want to build Ktor (main branch) on an Apple Arm, the build exits with: Resolving NPM dependencies using yarn' returns 139.
I don't know the exact reason, but it is resolved with the latest nodeJS version: 16.13.1.

Simple reproducer is attached.
nodeYarn.zip

We are getting more users and generator gets higher RPS rate which leads to memory usage growth.

Most of the requests are first-page requests from IDE (as logs show)
We need to consider limiting requests from IDE via hardcoding first page content and only make requests in background in case user really does something.

Created an empty project with Gradle and only added the following dependencies:

dependencies {
    testImplementation(kotlin("test"))
    implementation("io.ktor:ktor-client-core:1.6.7")
    implementation("io.ktor:ktor-client-cio:1.6.7")
}

According to Hadi, this should give me autocomplete to add the feature and related dependency :)

Reproduced on

• IDEA: 2022.1 EAP nightly, #IU-221.4286, built on February 10, 2022
• Kotlin: 221-1.6.20-RC-138-IJ4286

Migrations have known problems when it comes to MPP due to the lack of support of Kotlin MPP in IDE.
We must not show migration notification and/or perform migrations on MPP modules.

The main issue is that the current build tools API in IntelliJ (see DependencyModifierService) does not work properly with Kotlin MPP DSL in Gradle because this DSL is not supported.

If you run a migration for Ktor that tries to work with MPP dependencies in the same way as with a normal dependencies, it will just add a new outer block of dependencies { ... } in your build script. Instead, it must be adding dependencies inside macOs64 { dependencies { ... } } or other similar places for all relevant platforms

IU-221.4501.155, JRE 11.0.14+9-b1993.2x64 JetBrains s.r.o., OS Mac OS X(aarch64) v12.2.1, screens 5120.0x2880.0; Retina

Steps to reproduce the issue

• install language pack
• start IntelliJ IDEA
• create new Ktor project
• at plugin page, search "json"
• click "Add" for kotlinx.serialization

Expected

... プラグイン が追加されました

Actual:

... プラグインs が追加されました

Seems like "s" is added in a code for a message in English, to make "plugin" as "plugins"(plural), which is not appropriate for messages to be localized.

There were similar issues in IDE/bundled plugin and they were fixed already. Need a similar fix with Ktor (plugin?) as well.

Nightly 2022.1

Currently, tests for endpoints may appear in any order in multi-test dialogs and in the created tests file itself. This is hardly testable and for larger projects the order of the tests might be a mess.

Instead of showing them in random order, we can sort them by URL/HTTP method and then they will look prettier and it will be easier to test them since the order is always the same and it does not depend on what we found first.

Migrations are project-wide operations and they may affect the state of the project making it not compilable. This is a dangerous operation and it's recommended to add a bookmark in local history so that one may roll back to the state right before the migration.

Hello,

The default version when creating a ktor project with IDEA 2021.3.1 is 2.0.0-beta-1, but the last published version for ktor-locations is https://search.maven.org/artifact/io.ktor/ktor-locations/1.6.7/pom

This causes the first build to fail with the following error.

Issues:

1. Some people work on multi-module projects in mono repositories and they don't want to migrate the whole project (this will disturb other teams when changing irrelevant modules)
2. We are always showing this notification once a new version arrives. There must be an option like "Don't show again"
3. We are suggesting EAPs and Betas as well as stable releases. There must be an option to select migration version levels.

1. Run IDEA 2021.3.
2. Open the https://github.com/ktorio/ktor-documentation/tree/main/codeSnippets project and switch to the 2.0.0 branch.
   => IDEA suggests migrating this project to 1.6.6.

P.S. Maybe it's related to absense of the 2.0.0-eap version in a plugin for IDEA 2021.3.

The following code (Kotlin 1.6.10, Ktor 1.6.7, Java 17.0.1, jvmTarget = "1.8") reproduces the error:

@Serializable
data class Age(val value: Int)

@Serializable
data class Update<T>(val old: T, val new: T)

fun main() {
    embeddedServer(Netty, port = 8080) {
        install(ContentNegotiation) {
            json()
        }
        routing {
            update<Age>()
        }
    }.start(wait = true)
}

inline fun <reified T> Route.update() {
    post("/") {
        val update = call.receive<Update<T>>()
        application.log.info("update=$update")
        call.respond(HttpStatusCode.OK, "OK")
    }
}

Sending the following request:

$ curl -v -H "Content-Type: application/json" -POST http://localhost:8080/ -d '{"old":{"value":1},"new":{"value":2}}'

makes server throw:

Hi.
I am having problems with websockets and jetty.
Everythings works fine when execute my app as stand-alone, but when i pack the app in a war, and deploy it to an external jetty i am having problems with websockets connection.
When i open a websockets conneciton i get the following exception:

21-Mar 08:10:55.349 ERROR - 101 Switching Protocols: GET - /api-sample/ws
java.lang.ClassCastException: org.eclipse.jetty.server.HttpConnection cannot be cast to org.eclipse.jetty.io.Connection

I have been inspecting the code, and the problem seems to be in this file:

https://github.com/ktorio/ktor/blob/master/ktor-server/ktor-server-jetty/jvm/src/io/ktor/server/jetty/internal/JettyUpgradeImpl.kt

In the line 25:

val connection = servletRequest.getAttribute(HttpConnection::class.qualifiedName) as Connection

Tries to do a cast that fails , because the connection is an HttpConnection.

it takes couple of seconds to stop running app via CTRL+C

https://ktor.io/docs/status-pages.html#exceptions"Each call is only caught by a single exception handler, the closest exception on the object graph from the thrown exception. When multiple exceptions within the same object hierarchy are handled, only a single one will be executed."

In Spring Framework, its possible to return a Thymeleaf fragment. Is such feature also available in Ktor Thymeleaf Plugin?

What steps will reproduce the issue?
Version: Ktor 2.0.0-eap-329

install(SinglePageApplication) {
    useResources = true
    filesPath = "static"
}

And put an index.html file under src/main/resources/static.

Try GET /a.
What is the expected result?

index.html should be served, as this is supposed to be used with SPAs.

What happens instead?

404.

The SPA plugin code is like this:

static(applicationRoute) {
    if (usePackageNames) {
        resources(filesPath)
        defaultResource(defaultPage, filesPath)
    } else { ... }
}

Where defaultResource is:

public fun Route.defaultResource(resource: String, resourcePackage: String? = null) {
    val packageName = staticBasePackage.combinePackage(resourcePackage)
    get {
        val content = call.resolveResource(resource, packageName)
        if (content != null) {
            call.respond(content)
        }
    }
}

It uses get, which only matches the root route and nothing else. If you do something like this, then it will give the behavior suitable for a SPA.

routing {
    route("/") {
        resources("static")
       }
    route("/*") {
           defaultResource("index.html", "static")
    }
}

The adequate test cases were completely missing, as the tests only checked for behavior on files that exists.

I am not sure what is to blame but URLs such as:
file:\C:\Users\spand\IdeaProjects\hltv\dust2\dust2-main\build\libs\dust2-main.jar!\dust2
can end up in the list of paths to watch in ApplicationEngineEnvironmentReloading. This fails as described below. Can we either ignore them or clean up these paths ? (both file: prefix and the !\dust2 suffix seem irrelevant)

private fun watchUrls(urls: List<URL>) {
        val paths = HashSet<Path>()
        for (url in urls) {
            val path = url.path ?: continue
            val decodedPath = URLDecoder.decode(path, "utf-8")
            val folder = File(decodedPath).toPath() <----

Hi, Under the load scenario we are testing in my team lately, Ktor is using way more memory than other libraries, like Kooby(Jooby).

jdk1.8.0_221

After 500 seconds of stress tests of the same 4 endpoints, check the memory and CPU usage:

Jooby 2.13.0:

Ktor:

Ktor implementation code:

server:

embeddedServer(
    Netty,
    host = ip,
    port = port,
    module = Application::module,
    configure = {
        requestQueueLimit = 8
        runningLimit = 5
        shareWorkGroup = true
        configureBootstrap = {
            group(NioEventLoopGroup(8, Executors.newCachedThreadPool()))
        }
    }
).start(wait = true)

features:

install(DefaultHeaders)
install(ContentNegotiation) {
    register(ContentType.Application.Json, JacksonConverter(JSON))
}

routes:

fun route(parentRoute: Route) {
    parentRoute.invoke {
        post("/games/{gameId}/validate") { call.respond(HttpStatusCode.MethodNotAllowed) }

        post("/games/{gameId}/play") {
            call.respond(HttpStatusCode.OK, "hola")
        }

        get("/games/{gameId}/config") {
            call.respond(HttpStatusCode.OK, "hola")
        }

        post("/games/{gameId}/checksum") {
            call.respond(HttpStatusCode.OK, "hola")
        }

        get("/games/{gameId}/version") {
            call.respond(HttpStatusCode.OK, "hola")
        }

        get("/games/{gameId}/initialize") {
            call.respond(HttpStatusCode.OK, "hola")
        }

        post("/games/{gameId}/evaluate/{objectiveId}") {
            call.respond(HttpStatusCode.OK, "hola")
        }
    }
}

As you can see, the endopints are quite simple.

The test:

We used Gatling to stress the servers, this is the code:

BasicSimulation.kt

Basically, 500 users per second peform 4 api calls.

Any further question, please let me know.

Jte is a template engine similar to freemarker, you can read more about it here: jte.gg

I think it would make a great addition to the Ktor server plugins, as it directly compiles templates to .class files for fast view generation.

Json string of 4MB becomes 12MB while encoding with CBOR. It should reduce size. Is there anything that can help me to reduce response size?

val bytes = Cbor.encodeToByteArray(jsonString)

Hi! It would be nice to add this methods to PlaceholderList:

• isNotEmpty()
• size

For example for cases like:

class TodoTemplate : Template<FlowContent> {

    val item = PlaceholderList<UL, FlowContent>()
    
    override fun FlowContent.apply() {
        if (item.isNotEmpty()) {
            p { +"Number of tasks: ${item.size}" }
            ul {
                each(item) {
                    li {
                        insert(it)
                    }
                }
            }
        }
    }
}

The headers object in OutgoingContent is empty even if headers has been set on the response.

Hi,

I'm using ktor 1.6.5 with Netty TCNative 2.5.0. When I try to active the AutoReload configuration using the example from https://ktor.io/docs/auto-reload.html#enable

I got this error:

So, the ktor-server-host-common-jvm.1.6.5.jar at folder io.ktor.server.engine, inside the file ApplicationEngineEnvironmentReloading.kt is trying to filter the URL's obtained from the class path:

line 163
val allUrls = baseClassLoader.allURLs()

And it's trying to filter the url's using the patterns configured in my application.conf

watch = [classes, resources]

After filter all content, at line 193

watchUrls(watchUrls)

still reaming one URL with the format "jar:file:/...." and that line is generating the error.

Thank you!

<form action="/upload" method="post">
    <input type="file" name="test1" id="test1" multiple>
</form>

form.forEachPart {
            when (it) {
                is PartData.FileItem -> {
                    when (it.name) {
                        "test1" -> fileBytes = it.streamProvider().readBytes()
                    }
                }
          }
}

if user choose upload multiple files, the stream only contains the first file, and others will be lost.

In case if receiveEntireContent of DoubleReceive feature has been setup to true function readPart of MutliPartData will take a lot of time:

Installing example:

install(DoubleReceive) {
    receiveEntireContent = true
}

Some routing example:

val multipart = call.receiveMultipart()

multipart.readPart() // in case if here should be FileItem it take a lot of time to handle it
// ...

When adding modules for dependency injection with Koin (using latest version 3.1.4) there is a weird bug in versions 1.6.6+

Here's my repo. This error can easily be mitigated by migrating down to Ktor version 1.6.5 and under, and only surfaces in 1.6.6 and higher.

Here's is a link to the branch where I added it and had to migrate my Ktor version down: https://github.com/JimmyMcBride/boruto-server/tree/19-create_all_heroes_endpoint_p1

This issue was imported from GitHub issue: https://github.com/ktorio/ktor/issues/384

This is a follow up to #80. Apparently, responses were fixed, but there are still issues with the requests.

Request with Content-Type: application/json is decoded not as UTF-8, while request with Content-Type: application/json; charset=utf-8 is decoded correctly. Both has to behave the same and be decoded as UTF-8.

Currently I am doing the following:

install(ContentNegotiation) {
    gson(ContentType.Application.Json.withCharset(Charset.forName("UTF-8"))) {
        registerTypeAdapter(Instant::class.java, InstantTypeConverter()) // not related
    }
}

However, when I inspect the response in the browser, I see the following:

Accept
	application/json, text/plain, */*
Accept-Encoding
	gzip, deflate
Accept-Language
	vi-VN,vi;q=0.8,en-US;q=0.5,en;q=0.3
Connection
	keep-alive
Content-Length
	176
Content-Type
	application/json

The charset is missing from Content-Type as well as Accept. This causes encoding issues. For example, I get back Végh instead of Végh

I haven't checked the details yet but some tests using Ktor's testing module in our project detected a binary-compatibility issue.

• https://github.com/slackapi/java-slack-sdk/runs/4087459078?check_suite_focus=true

As a workaround, we locked the version to 1.6.4 and it worked for us. https://github.com/slackapi/java-slack-sdk/commit/8a9063bf694376074a3a4bed93871416f48241c3

I hope this helps.

Many plugins reference RFCs, such as the one for ForwardedHeaders or AuthScheme, and yet it would make sense to reference our own documentation (which in turn actually references RFCs'). This should be applied consistently across the entire code base.

Right now we're supporting automatically only hocon configuration format(with application.conf file located in the resources folder). Unfortunately, this format is supported only with using external plugins so it's hard to provide any navigation features.

As the solution, we want to have the YAML support(same as HOCON) with a brief review of the API on how to fetch properties.

I am using Ktor version 1.5.0. and when I try to upload multipart form data, getting server exception(500 error) with the following error.

I see the following exception on an Android 10 Redmi 8 phone when making a get request to a Ktor server running on another device:

kotlinx.coroutines.channels.ClosedReceiveChannelException: Channel was closed

at kotlinx.coroutines.scheduling.CoroutineScheduler$Worker.runWorker(CoroutineScheduler.kt:678)at kotlinx.coroutines.scheduling.CoroutineScheduler$Worker.run(CoroutineScheduler.kt:665)

The server is a Ktor server hosted on another Android device.

Sever engine: Netty

Client Engine: CIO

The issue only happens if SSL is enabled on the server.

I have only experienced this with the Xiaomi Redmi device, and I have tested quite a wide range of devices.

Any ideas?

So I get that I'm doing something weird here since I'm trying to conditionally handshake websocket connections, but I think the issue may be real? I can't reproduce it any other way, so if there's an alternative to make conditional handshaking work, I'd totally take that too.

The issue is that cancelling a pipeline execution can leave the websocket connection open, but indefinitely stuck (until the client closes the connection). This is rather easily demonstrated by the following code:

suspend fun ApplicationCall.redirectInternally(path: String, subject: Unit) {
    val cp = object : RequestConnectionPoint by this.request.local {
        override val uri: String = path
    }
    val req = object : ApplicationRequest by this.request {
        override val local: RequestConnectionPoint = cp
    }
    val call = object : ApplicationCall by this {
        override val request: ApplicationRequest = req
    }

    this.application.execute(call, subject)
}

get("/ws") {
    val job = launch {
        call.redirectInternally("/ws/internal", Unit) // cond
    }
    delay(100) // wait for handshake
    job.cancel()
}
webSocket("/ws/internal") {
    try {
        delay(3000) // do work
    } finally {
        this.close() // No effect since SendChannel is cancelled
    }
}

I've debugged this to the SendChannel getting cancelled with the context cancellation, yet the connection isn't closed beforehand. When the ktor connection management tries to send its Close frame, the SendChannel just bails out. withContext(NonCancellable) and sending a manual close frame doesn't help either, since the channel stores the original closedForSend exception locally.

Cancelling the socket from within the webSocket handler works totally fine - it's only an issue when it's cancelled by the parent job.

This also only impacts the Netty engine, CIO closes the websocket with a 1000 status code (internally, explicit closes aren't necessary/don't have an effect either). Not sure about other engines.

I made a web app using Ktor following this tutorial.

This app uses Ktor for the server, Kotlin/JS for the frontend, and MongoDB for the database.

I am now trying to deploy this app on Heroku and used MongoDB Atlas for the remote database.

But, whenever I try to perform a POST request through the app, it returns the following error:

Strangely, when performing a POST request through IntelliJ IDEA, it works perfectly fine returning 200 OK.

GET and DELETE request also performs as it should.

This is the code that performs the request:

suspend fun addShoppingListItem(shoppingListItem: ShoppingListItem) {

    jsonClient.post<Unit>(endpoint + ShoppingListItem.path) {


        contentType(ContentType.Application.Json)
        body = shoppingListItem

    }

}

And this is the code that handles the request:

route(ShoppingListItem.path) {

                get {

                    call.respond(collection.find().toList())

                }
                post {

                    collection.insertOne(call.receive<ShoppingListItem>())
                    call.respond(HttpStatusCode.OK)

                }
                delete("/{id}") {

                    val id = call.parameters["id"]?.toInt() ?: error("Invalid delete request")
                    collection.deleteOne(ShoppingListItem::id eq id)
                    call.respond(HttpStatusCode.OK)

                }

            }

I don't have a clue why this is happening, and thinking this might be a bug.

Thanks.

Hi, I have an issue on iOS side when trying HttpClient with iOS engine.

I tried the following code:

HTTPClient(Ios){
    engine{
        handleChallenge { session, task, challenge, completionHandler ->
                completionHandler(NSURLSessionAuthChallengeUseCredential, null)
        }
    }
}

However, when I build it, the build failed. NSURLSessionAuthChallengeUseCredential despite inheriting from NSURLSessionAuthChallengeDisposition is a type of Kotlin.Long, but the completion handler’s first param only take NSURLSessionAuthChallengeDisposition which is a type of platform.darwin.NSInteger. I tried converting NSURLSessionAuthChallengeUseCredential to int and at the build has no error, but when building it on Xcode, the following error appeared when the build failed:

Type mismatch: inferred type is Int but NSURLSessionAuthChallengeDisposition /* = Long */ was expected

The issue, I think, is on the completionHandler taking only platform.darwin.NSInteger, which caused this issue on Xcode. I would appreciate any help or explanation of this error.

I also made a thread on stack overflow regarding this issue:

Thank you for your attention.

I'm currently trying to create an application with kt/native for an rpi 0 but I want to be able to view data from the application from a web interface so I'm trying to use compose as my kt/js front end. I was wanting to use ktor as the web backend because I heard that as of 1.1.2 it supported kt/native but I was running into trouble and heard again that it's only supported in the eap releases so I tried that but still I'm running into trouble. Am I miss understanding and ktor doesn't support kt/native yet or am I doing something wrong

What steps will reproduce the issue?
1. create a route and give a generic;
2. post data from client with incorrect data
3. got 500
What is the expected result?

got 400 instead of 500

What happens instead?

got error code with 500

further more
if generic like

data class (val id:Int?,val name:Int?)

and the data is {id:50}, it will also cause an error, but , I expect to get this data

I use org.springframework.boot gradle plugin for packing ktor application into single jar, however resolution of resources does not work in nested jars.

    embeddedServer(Netty, host = config.server.host, port = config.server.port) {
        // ...
        routing {
           // ...
            static("/") {
                resources("static")
            }
        }
   }

I would say resourceClasspathResource function is guilty as it uses custom mechanism for loading resources and doesn't handle nested jars.

I am trying to create websocket in Android 6.0, it works fine in debug but websocket is closed continually in release mode. I have two different applications and it happens only one of them. I am using Netty, but tried with CIO and got same result. I am using ReconnectingWebSocket in client side and it catches closed event reason as undefined. I also tried with Ktor-2.0.0-beta-1 it hangs on for the index.html. I tried debugging in ktor WebSocket but could not catch any useful info. What could cause this problem?

Server:

private val ipAddress = ipAddressProvider.getLocalIpAddress()

private val server by lazy {
    embeddedServer(
        factory = CIO,
        port = port,
        host = ipAddressProvider.getLocalIpAddress()
    ) {
        install(WebSockets)
        routing {
            webSocket("/ws") { 
            // ...  
            }
            static("/") {
              // ... 
            }
        }
    }
}

fun launch() = coroutineScope.launch(Dispatchers.IO) {
        server.start(true)
}

...
class IpAddressProvider(private val context: Context) {

    fun getLocalIpAddress(): String {
        val wifiManager =
            context.applicationContext.getSystemService(Context.WIFI_SERVICE) as WifiManager
        return Formatter.formatIpAddress(wifiManager.connectionInfo.ipAddress)
    }
}

Server launches in Android application, if switch off wifi or wireless connection, app crashes with exception:

Ktor version 1.6.7

How to process this exception or any workaround to prevent crash and stop the server?

I noticed during the migration of my kmm library to kotlin 1.6.10 that having org.jetbrains.kotlinx:kotlinx-serialization-core:1.3.0 makes the build crash with the following error :

e: Compilation failed: null

 * Source files: 
 * Compiler version info: Konan: 1.6.10 / Kotlin: 1.6.10
 * Output kind: FRAMEWORK

e: java.lang.NullPointerException
	at org.jetbrains.kotlin.backend.konan.optimizations.DataFlowIR$SymbolTable.mapClassReferenceType(DataFlowIR.kt:520) ...

The crashes can be fixed by downgrading to org.jetbrains.kotlinx:kotlinx-serialization-core:1.2.2 .

There's a thread about this issue here https://kotlinlang.slack.com/archives/C3PQML5NU/p1641817165062900

We have a Kotlin multiplatform project targeting ios and android. We are communicating with our server via RSocket.
Everything works fine until you lock the device. After unlocking it, it just says:

Message from debugger: Terminated due to signal 13
@olme04 pointed me to this issue and adding signal(SIGPIPE, SIG_IGN) //Ignore signal workarounds the issue.

His answer can be found here.

Let me know if some more details is needed from me.

I used Ktor for DIY development, in the Ktor server back end can perception disconnection from the network, awaitContent,awaitClosed can success return from suspension, but in android disconnection from the network, these methods can not return.

Gitee :https://gitee.com/slientes/custom-ktor

Ktor version：1.6.0

Normally my routes are included in Jacoco test reports. However, if call another request inside the route with Ktor client, the post path is not included:

^^ post path is yellow

If I remove the nested request, then request path shows covered like expected.

I tested with Kover and that one shows the post instruction as tested, even with the client request:

How should I implement my nested request inside this handler so the Jacoco reports shows it as covered?

ktor:1.6.7

kotlin:1.6.10

The header function manages the Access-Control-Allow-Headers response header. There is also allowHeadersPrefixed and allowHeaders functions that manage the same header. It would be logical to rename header to allowHeader to make names more consistent.

The Deflater implementation is causing memory leaks when the response channel gets closed (for example when a peer resets the connection) and the gzipped content is larger than the ByteBufferChannel backing buffer (4088).

More exactly this happens for the ByteWriteChannel.deflated method which launches 2 coroutines, one that is reading the uncompressed body and is executing the compression, and one that is copying the compressed body in the response channel. The one which is doing the copying will close since the copyTo method throws the error when it cannot write and the coroutines stops but it is not terminated with exception as it is caught by the launchChannel code, so no cancellation is propagated. The coroutine which executes the compression will continue to run and could notice that the input channel (the one with the uncompressed body data) is closed and will exit, but in the case where compressed size is bigger than the buffer size (4088), it will enter in suspension and since nobody is there to consume the data, it will never be resumed.

This will cause 3 coroutines to remain hanging and never terminate, I attached a file with them and their stack traces.

I also attached a test which replicates the issue and remains hanging.

We have a test that checks the authentication in a Web Socket route. The route will return a non 200 status code with an error body in this case. When attempting to test this route using the test application the test hangs indefinitely as demonstrated here:

fun Application.testModule() {
    routing {
        // In our actual code this is a websocket route but it can respond with a non 200 error code
        get("/test") {
            call.respondOutputStream(status = HttpStatusCode.Forbidden) {
                write(ByteArray(1024 * 1024))
            }
        }
    }
}

withTestApplication({ testModule() }) {
    val regularCall = handleRequest(HttpMethod.Get, "/test") {}
    println("Regular call returned ${regularCall.response.status()}")

    val wsCall = handleWebSocket("/test") {}
    println("WS call returned ${wsCall.response.status()}")
}

The test hangs when ktor is trying to write the response body in the second case. If the body is small then it completes successfully.

The above is Groovy syntax (no parens), but shown as Kotlin syntax.

The above is Kotlin syntax (parens) but shown as Groovy syntax.

With KTOR-3614 the testApplication supports https calls to the internal TestEngine, but only if the requested port is explicit set to 80. This requires to set the host of a request to https://localhost:80/foo.

Expected: https://localhost/foo

Solution: Add a second connector listen on the default https port 443.

Hi guys, every time I make a request with ktor from my native part (iOS) I get leaks like these:

Could help me go deeper, and get the reason why of these leaks?

Library versions:

object Versions {
    const val iosTestTask = false
    const val foo = "8.6.8"
    const val kotlin = "1.5.31"

    const val androidGradlePlugin = "7.0.2"
    const val gradle = "gradle-7.2-bin"

    // Android
    const val compileSdk = 31
    const val minSdk = 23
    const val targetSdk = compileSdk

    // versions between modules can avoid behavior conflicts.

    const val coroutines = "1.5.1-native-mt"
    const val ktor = "1.6.3"
    const val openapigen = "5.3.0"
}

I've a coroutine presenter like this:

open class CoroutinePresenter(
    private val mainContext: CoroutineContext = ApplicationDispatcher
): CoroutineScope {

    private val job = Job()
    private val exceptionHandler = CoroutineExceptionHandler { _, throwable ->
        print(throwable)
    }

    override val coroutineContext: CoroutineContext
        get() = mainContext + job + exceptionHandler

    open fun cancelRequest() {
        cancel()
    }

    open fun onDestroy() {
        print("CoroutinePresenter onDestroy: cancel job!")
        job.cancel()
    }
}

As ApplicationDispatcher I wrote:

internal actual val ApplicationDispatcher: CoroutineContext = MainDispatcher()

internal class MainDispatcher : CoroutineDispatcher() {
    override fun dispatch(context: CoroutineContext, block: Runnable) {
        dispatch_async(dispatch_get_main_queue()) { block.run() }
    }
}

And I use Presenters like that:

    open val service: WeakRef<ApiService> = WeakRef(apiService)

    }

        val errorType: ErrorMessage.ErrorType? = null,
        val unexpectedError: String? = null,
        val indicatorAnimating: Boolean = false,
        val requestSucceeded: Boolean = false,
        val validationSucceeded: Boolean = false
    )

    open suspend fun <T : BaseRequestViewState, M : Any> requestAsync(
        returnT: (BaseRequestViewState) -> T,

        retrieveFromDb: (() -> T?)? = null,
        apiCall: suspend (ApiService) -> HttpResponse<M>,
        successfulHandler: (M) -> T,
        validationCall: (() -> T)? = null
    ): T {
        validationCall?.let {
            val validationViewState = it()
            if (!validationViewState.validationSucceeded) {
                return validationViewState
            }
        }

        initialViewStateHandler(
            returnT(
                BaseRequestViewState(
                    indicatorAnimating = true
                )
            )
        )

It's not easy to make a minimal working example because the HTTP client is generated from a swagger template.

I just started to investigate, but if you already have any clue, please let me know.

We're observing rare but recurring timeouts in production on Apache client requests with content lengths > 4KB (presumably 4088 bytes) when streaming the request body content from a ByteBufferChannel. Our use-case uses a ktor Netty server and Apache client to proxy the incoming request body out to a downstream service. We currently pass the ApplicationCall request content channel directly to the ktor client request body using a ReadChannelContent without any copying/joining of channels.

It appears that there might be a bug in ByteBufferChannel readAvailable(min: Int, block: (ByteBuffer) -> Unit): Int which is used by ApacheRequestProduer, where...

1. Buffer arrives with content >= 4088 bytes
2. writeFully writes 4088 bytes, flushes
3. 4088 bytes availableForRead
4. writeFully suspends due to full channel
5. ApacheRequestProduer attempts to read via readAvailable
6. 4088 bytes availableForRead; availableForRead set to 0
7. Apache encoder consumes zero bytes (unclear why, maybe just not ready?)
8. readAvailable resumes the writeOp via bytesRead(state, 0)
9. Useless flushing, can't write anything because it's still full
10. readAvailable moves 4088 bytes back to pendingToFlush via state.completeWrite(4088 - 0)
11. reading block ends but capacity is never flushed again to move the 4088 bytes back to availableForRead
12. ApacheRequestProducer suspends waiting for content; writing coroutine (Netty) suspends waiting for the channel to be read

At this point, the coroutines are deadlocked but a manual flush should open it back up.

I'm not familiar enough with ByteBufferChannel to open a PR with a fix but this single line change seems to mitigate the problem in my test environment: https://github.com/ktorio/ktor/compare/1.6.7...jhead:1.6.7-channel-fix?expand=1

This might impact other clients but last I checked, Apache was the only one I saw using this non-suspending readAvailable API.

Hi! Is there a way to see the API docs of the stable version of Ktor? https://api.ktor.io/ only shows me 2.0.0-beta-1 and I can't find a way to switch versions (e.g. to 1.6.7) in the docs.

I created a clean build of the Ktor server via a plugin for IDEA

My build.gradle.kts

Possible solution:
 - Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html

And by the way, it doesn't matter if it's a new project or an old one, the errors are the same here and there.

I tried clearing the cache in IDEA, tried clearing the cache in gradle, tried changing the version of Ktor.

None of this helped me.

Any idea how to fix this?

I managed to reproduce a memory leak involving WebSocket. Run it and you'll see that it consumes all available memory. In my system that happens within the first ten thousand iterations, even when it shouldn't.

I have a Ktor Back-End and react front-end both deployed and running in Heroku. I use Google OAuth for my authentication but on Chrome followup requests after the login have an empty UserSession causing a 401 response. On FireFox this works fine.

This is my code in my Application.kt file

@Suppress("unused") // application.conf references the main function. This annotation prevents the IDE from marking it as unused.
fun Application.module() {
    configureHTTP()
    install(XForwardedHeaderSupport) //don't know if this helps but if I remove this line the server crashes when authenticating

    val googleOauthProvider = OAuthServerSettings.OAuth2ServerSettings(
        name = "google",
        authorizeUrl = "https://accounts.google.com/o/oauth2/auth",
        accessTokenUrl = "https://accounts.google.com/o/oauth2/token",
        requestMethod = HttpMethod.Post,
        clientId = System.getenv("OAUTH_CLIENT_ID"),
        clientSecret = System.getenv("OAUTH_SECRET"),
        defaultScopes = listOf("https://www.googleapis.com/auth/userinfo.profile")
    )
    val httpClient = HttpClient(CIO) {
        install(JsonFeature) {
            serializer = KotlinxSerializer()
        }
        install (Logging)
    }

    install(Sessions) {
        cookie<UserSession>("user_session") {
            cookie.extensions["SameSite"] = "None"
            cookie.secure = true
        }
    }
    install(Authentication) {
        oauth("auth-oauth-google") {
            urlProvider = { System.getenv("OAUTH_CALLBACK_URL") }
            providerLookup = { googleOauthProvider }
            client = httpClient
        }
    }
    install(Koin) {
        modules(databaseModule)
    }
    configureRouting(httpClient)
    configureSerialization()
    configureMonitoring()
    configureSecurity()

}

This is my code in the configureHttp method

fun Application.configureHTTP() {
    install(CORS) {
        method(HttpMethod.Options)
        method(HttpMethod.Put)
        method(HttpMethod.Delete)
        method(HttpMethod.Patch)
        header(HttpHeaders.Authorization)
        header(HttpHeaders.ContentType)

        allowNonSimpleContentTypes = true
        allowCredentials = true

        host("frontend-host", listOf("https")) //replaced for security
        host("localhost:3000")
    }

}

I'm very new to ktor and did not find anything in the documentation or on forums that could help me. So I created this issue hoping someone could help me out.

Thanks in advance!

Since the Ktor plugin is bundled, we shouldn't promote to install it and recommend using IDEA Ultimate instead

https://github.com/ktorio/ktor/pull/2003

https://github.com/ktorio/ktor/pull/2188

Hello!

I'm using Ktor in a KMM app, and I am not having any kind of problem in Android, but in iOS it behaves weird. I don't have the HttpCookies plugin installed, because I'm handling and storing the session cookie outside of Ktor.

What happens is that the very first request that is sent to the server (GET /api/session) contains a Set-Cookie header in the response, and for this request I don't save the cookie nor do anything with it, the request serves only to check if there is a session based solely on the response of the server. Both in Android and iOS we get the Set-Cookie header for this request.

The second request (POST /api/session) is made after the user attempts to log in using their credentials. For this request, we need the response to contain the Set-Cookie header so we can store the session token it contains and then pass it onto further requests. This happens in Android, but not in iOS. I tried removing the first request, and magically, I get a cookie for this one!

Is the iOS backend automatically storing and passing the cookie without my knowledge or consent? As I said before, I didn't install the HttpCookies plugin.

I am receiving a cookie looking like that 384f8bdb/sessid=GLU787LwmQa9uLqnM7nWHzBm; path=/.
Using the HttpCookies feature, i want ktor to send the 384f8bdb/sessid=GLU787LwmQa9uLqnM7nWHzBm for all subsequent requests. Unfortunately, the cookie is parsed in a way that ignore everything after 384f8bdb.
I've tracked down the issue to this point:
(commonMain/io/ktor/http/Cookie.kt)

@ThreadLocal
private val clientCookieHeaderPattern = """(^|;)\s*([^()<>@;:/\\"\[\]\?=\{\}\s]+)\s*(=\s*("[^"]*"|[^;]*))?""".toRegex()

When I check the regex against the cookie, it gives the following results:
Problem with that is, the cookie storage only save 384f8bdb="" so the session id is never sent to the server in the following requests.

Is there any workaround for that (using the HttpCookies feature) ?
Is that the wanted behavior for ktor ?

Thanks

To reproduce run the following test:

@Test
fun test() = runBlocking {
    val client = HttpClient(MockEngine) {
        engine {
            addHandler { request ->
                assertEquals("test=value", request.headers["Cookie"])
                respond("")
            }
        }

        install(HttpCookies) { // Without HttpCookies plugin the test passes
            storage = AcceptAllCookiesStorage()
        }
    }

    client.get<Unit>("/example") {
        cookie("test", "value")
    }
}

In the docs sample (https://ktor.io/docs/auth.html#bearer), the bearer authentication is used to access the Google API. The problem is that the Google API doesn't return the WWW-Authenticate with the 401 response when an access token is expired. This causes that the refreshTokens callback isn't called and there is no way to refresh a token.

The log below doesn't have the WWW-Authenticate header in a response:

When creating a Kotlin Multiplatform Mobile Library using Ktor, when creating a httpclient with an empty constructor(should use default httpclientengine), then the following exception is thrown:

kotlin.IllegalStateException: Failed to find HttpClientEngineContainer. Consider adding [HttpClientEngine] implementation in dependencies.[kotlin.Exception]

I have added the following to my build gradle:

val iosMain by getting {
    dependencies {
        implementation("io.ktor:ktor-client-ios:$ktor_version")
        implementation("org.jetbrains.kotlinx:kotlinx-serialization-core:$serialization_version")
    }
}
val iosSimulatorArm64Main by getting
iosSimulatorArm64Main.dependsOn(iosMain)
val iosTest by getting {
    dependencies {
        implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core:$coroutines_version")
    }
}
val iosSimulatorArm64Test by getting
iosSimulatorArm64Test.dependsOn(iosTest)

Android behaves as expected but for some reason ktor is not using the default client engine.

Just for clarity, simply doing:

private val httpClientConfig: HttpClientConfig<*>.() -> Unit = {
    install(JsonFeature) {
        serializer = KotlinxSerializer()
    }
    install(Logging) {
        logger = Logger.DEFAULT
        level = LogLevel.ALL
    }
}
HttpClient(httpClientConfig)

In the common layer, throws the exception, but i would expect it would use the default client engine for each of the platforms respectively.

In site operations, it is useful when you have retries to be able to see retry traffic from the server viewpoint, as well as control retry decisions. This helps in cases where retry logic is causing storms of traffic across many clients even with falloff.

What is needed is the retry plugin to allow:

• when "deciding to retry or not", the lambda answering this questions requires visibility of the try count AND the request/response instances (i.e. response may have a header saying DON'T retry, or the opposite with a Retry-After header). Looking at count, headers, error code are all important.
• when "deciding the delay of the retry", the lambda answering this question needs the retry count AND the request/response instances since it might respect Retry-After style headers (https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Retry-After). This applies to rate limiter headers (remaining, limit, reset, etc) as well. Also x-no-retry custom headers from the ops team blocking retries in an emergency at their edge firewall. Looking at count, headers, error code are all important.
• before a retry the opportunity to modify the request object in needed based on the retry count and the request/response instances. This allows setting ops headers such as x-retry-count: 5 which again allow edge control over retries. For example, in an outage recovery I might want to kill all retries with a count above 1, or any with a count at all to stop retries for a moment. The server needs to see evidence of the retry to do so, therefore modifying the headers is important.

The HttpRequestRetry is useful but incomplete as it takes into account what the client wants, but not what a server/ops might want and to cooperate.

The request here is for the hooks for the events with the correct data, not implementing the specific examples given. They vary wildly other than Retry-After which even browsers implement (https://stackoverflow.com/questions/3764075/retry-after-http-response-header-does-it-affect-anything).

It would be nice to be able to modify headers for instance between retry requests. Per customer feedback https://twitter.com/RevDocApatrida/status/1468176917513785346

ktor-client-auth fail a Digest auth challenge (Using version 2.0.0-eap-275)

After investigation, I can say that this is not a bug per se as the RFC (https://datatracker.ietf.org/doc/html/rfc2617) say at section 3.2.1 that algorithm attribute is optional and `If this is not present it is assumed to be "MD5"`.

But some server implementation are buggy (JBoss management on JBoss EAP 7.1 to name one), and won't work without the algorithm attribute present in challenge response (Got a 401).

So I would like to see it added or an option to force it's presence.

Code:

private val ktorHttpClient = HttpClient(OkHttp) {
	install(Auth) {
		basic {
			credentials { BasicAuthCredentials(username = "[REDACTED]", password = "[REDACTED]") }
		}
	}
	install(Logging) {
		logger = object : Logger {
			override fun log(message: String) {
				Log.d("Logger Ktor =>", message)
			}
		}
		level = LogLevel.ALL
	}
}

private suspend fun login() {
	val url = "https://api.backblazeb2.com/b2api/v2/b2_authorize_account"
	val resp = ktorHttpClient.get<HttpResponse>(url)
	Log.d("BACKBLAZE", resp.readText())
}

Log output:

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 }.

In my project i need pass any attributes when intercept the call with an authorization, the attributes are put correctly in the call request but when get any attribute this generate a exception: java.lang.IllegalStateException: No instance for key AttributeKey: caller.id. But I print the list of AttributeKeys and the key is in the list: [AttributeKey: caller.siteId, AttributeKey: AuthContext, AttributeKey: SendPipelineExecutedAttributeKey, AttributeKey: EngineResponse, AttributeKey: caller.scopes, AttributeKey: caller.id, AttributeKey: client.id, AttributeKey: caller.status], I need help please.

Hi Team!

Within your class: io.ktor.http.URLBuilder.kt you changed the signiture of Url from

public data class Url

To

public data class Url internal constructor

Which prevents the usage for us. We are using it like:

private fun sanitize(url: Url): Url {
    return Url(
        protocol = url.protocol,
        host = url.host,
        specifiedPort = url.specifiedPort,
        encodedPath = url.encodedPath,
        parameters = sanitizeParameters(url.parameters),
        fragment = url.fragment,
        user = url.user,
        password = url.password,
        trailingQuery = url.trailingQuery,
    )
}

Can you provide a fixed version e.g. 1.6.7 ? This would be the best for all customers of your library.

or provide a fix. I guess it should work somehow with the URLBuilder, but the new ParameterBuilder makes the compiler unhappy.

The documentation for "Creating HTTP APIs" for Ktor has a section on "Automated Testing". As a part of the testing approach, it is suggested that a "testing = true" parameter needs to be added to the Application.module() function. However, a reason is not given as to why this is necessary to do.

Based on my experience, making changes to production code for the sake if testability is a code smell and should be avoided. Therefore, I tried to remove this "testing" parameter and so far as I can tell. it appears that the test still functions as expected.

Searching for other documentation regarding testing Ktor, the "Testing Overview" section illustrates the most basic of testing approaches and it doesn't appear as if adding a "testing" parameter is necessary.

I would be happy to make a PR on this part of the documentation to clarify, however before doing so I thought it would be best to confirm with the team:

• Was there a reason for adding the "testing" parameter? Is the code still able to be properly tested without this parameter?
• Given my lack of knowledge around Ktor and testing Ktor, are the other considerations with regards to testing that need to be taken into consideration for the documentation?

If the above points can be clarified I'd be happy to make a PR for this. Thank you!

The sendWithoutRequest method mentionned here https://ktor.io/docs/eap/auth.html#digest is not available

I don't know if you expect bug report about documentation about EAP, sorry if you know the doc is outdated and plan to update it later.

And if I work my way to enable it, their is an NPE. As a workaround, I did :

        install(Auth) {
            providers+=object:AuthProvider by DigestAuthProvider({DigestAuthCredentials("foo", "bar")}, "MyRealm"){
                val notFirst= Collections.synchronizedSet(mutableSetOf<String>())
                override fun sendWithoutRequest(request: HttpRequestBuilder): Boolean {
                    return !notFirst.add(request.url.host+":"+request.url.port)
                }
            }

If not used, EACH call start without auth header.... So each call make 2 request (first the 401, then the 200)

Also, the nc attribute of the authorization header is incremented even when the challenge is reset.

Here: https://ktor.io/docs/cors.html#hosts

it gives "subDomains" as an example like so: subDomains = listOf("en,de,es")

but I'm pretty sure it should be subDomains = listOf("en", "de", "es")

1. Run IDEA 2021.3.
2. Open the https://github.com/ktorio/ktor-documentation/tree/main/codeSnippets project and switch to the 2.0.0 branch.
   => IDEA suggests migrating this project to 1.6.6.

P.S. Maybe it's related to absense of the 2.0.0-eap version in a plugin for IDEA 2021.3.

Ktor Version and Engine Used (client or server and name)
1.2.5 and 1.3.0-beta-1, server, netty and CIO

Describe the bug
When using the base64 encoding for a session cookie, the correct cookie is not picked up.

In my repro example below I am basically calling /login, which sets the session, and then /, where the session is evaluated. When using base64 encoding, the second call doesn't succeed, as no session is found.

Important to notice that this works with all other encodings, and even with base64 in the test engine.

To Reproduce
Minimal repro here: https://github.com/AndreasVolkmann/ktor-session

Steps to reproduce the behavior:

1. Start the server
2. Go to localhost:5000/login which should return Logged in and set the session / cookie.
3. Go to localhost:5000 where an error is shown

When changing the encoding, the above scenario works.

Expected behavior
The session cookie should be set and valid for the next call, just like with all other encodings and under test.

Tested with multiple browsers and postman.

Netty Engine flushing to the channel twice for every response now (for header and content). The flush is an expensive operation and it's called for every response , so it makes Netty engine slow.
The solution is to make flush only when reading responses is completed (when user starts waiting for responses).
Rewrite includes ktor-server-netty module.

When adding modules for dependency injection with Koin (using latest version 3.1.4) there is a weird bug in versions 1.6.6+

Here's my repo. This error can easily be mitigated by migrating down to Ktor version 1.6.5 and under, and only surfaces in 1.6.6 and higher.

Here's is a link to the branch where I added it and had to migrate my Ktor version down: https://github.com/JimmyMcBride/boruto-server/tree/19-create_all_heroes_endpoint_p1

Ktor Version
1.6.4

Ktor Engine Used
Netty Server

Behaviour
Only some of NettyApplicationEngine's properties are loaded from ApplicationConfig set when using EngineMain.

Expected behaviour
After reading https://ktor.io/docs/engines.html#configure-engine I assumed it would be possible to configure all properties (besides the functions) via the configuration files.
Missing runningLimit, requestReadTimeoutSeconds and tcpKeepAlive

When setting basename

  install(DropwizardMetrics) {
            registry = metricRegistry
            baseName = "my.prefix"
        }

metrics for endpoints does not get prefixed with the baseName I set.

When GET-ing /some/path/ I get metrics /some/path/(method:GET) but I expect my.prefix./some/path/(method:GET)

I am using ktor 1.5.2

To reproduce run the following code and make a GET / request:

fun main() {
    val env = applicationEngineEnvironment {
        developmentMode = true

        connector {
            port = 4444
        }

        module {
            routing {
                get("/") {
                    throw RuntimeException()
                }
            }
        }
    }

    embeddedServer(Netty, env).start()
}

In the stack trace I observe a line: io.ktor.util.pipeline.SuspendFunctionGun.execute. Since development mode is enabled I expect that only DebugPipelineContext is used but for all routes, except for the Routing, SuspendFunctionGun is executed.

To reproduce run the :ktor-client:ktor-client-mock:compileTestKotlinJvm Gradle task on the latest main branch.

I see that the package name for some of the packages under serialization are named as "serializaion". This is one example. If this is intentional, please feel free to close the issue.

When the application is run in development mode, the hibernate result class check fails with the following message:

This error does not occur when development mode is switched off.

We should drop everything before 1.6.6

It may be similar to this issue.

If the Logging plugin is installed the Ktor client deadlocks/blocks sometimes after BODY START is printed to the console.

The response is still getting returned back to the calling function, but any future requests will block.

It doesn't happen every time, but it is reasonably easy to reproduce it with the attached Sample app.

When the HttpClient has LogLevel.ALL or LogLevel.BODY sometimes the logs stop and nothing happens after, everything work fine in Android.

testErrorHandling fails on JS with assertFailsWith.

My Ktor JS client is not receiving proper headers in browser target, despite it being working in nodejs target.

I reproduced the issue using a simple Ktor server:

data class UserSession(val id: String, val count: Int)

fun main() {
    embeddedServer(Jetty, port = 9000, host = "0.0.0.0") {
        install(CORS) {
            anyHost()
        }
        install(Sessions) {
            cookie<UserSession>("user_session")
        }
        
       routing {
            post("/login") {
                val name = call.receive(String::class)
                call.sessions.set(UserSession(id = name, count = 0))
                call.respond(HttpStatusCode.NoContent)
            }
            get("/session") {
                val userSession = call.sessions.get<UserSession>() ?: error("no session")
                call.respond(userSession.id)
            }
        }
    }.start(wait = true)
}

On the client side, my client build.gradle.kts looks like:

kotlin {
    jvm()
    js(IR) {
        browser()
        nodejs()
    }
    // ...
}

Consider this test:

@Test
fun shouldLogin() = runTest {
    val client = HttpClient(Js) {
        install(HttpCookies)
        install(Logging)
    }

    val name = "test"
    client.post<String>("http://0.0.0.0:9000/login") { body = name }

    val username = client.get<String>("http://0.0.0.0:9000/session")
    assertEquals(name, username)
}

I observed the following:

It looks like common headers are absent, especially the crucial cookie related ones.

I do not know if it is a bug, or if I misconfigured something, any idea?

EDIT: I changed the issue from Multiplatform, to JS only as this is reproducible even using only the JS engine in two different targets.

After update ktor client from 1.6.4 to 1.6.6 below code throws exception on android 26 also that error is related to the JDK version because on android 31 you cannot reproduce it.

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 }.

The Ios engine uses NSURLSession from the Foundation framework, which can be used not only for iOS but for other operating systems, including macOS, tvOS, etc. This leads to confusion that the Ios engine can be used for iOS devices only. So it makes sense to rename the engine and artifacts to something more general, for example, Darwin or smth else.

Can't send request from ServiceWorker, it fails with `require is not defined`

ServiceWorker scope doesn't have the window object.

This is a suggestion for service worker support: https://github.com/ktorio/ktor/pull/2696

Hello.

We are using Ktor in a KMM project with OKHttpEngine on Android side. Sometimes, on Android side, when sending a get request, the client throws an exception

SocketException("Socket is closed")

After a long research of Ktor source code, I came to the conclusion that the HTTP request is being processed successfully, an error occurs at the time of reading the request data.

    private suspend fun executeHttpRequest(
        engine: OkHttpClient,
        engineRequest: Request,
        callContext: CoroutineContext,
        requestData: HttpRequestData
    ): HttpResponseData {
        val requestTime = GMTDate()
        val response = engine.execute(engineRequest, requestData)

        val body = response.body
        callContext[Job]!!.invokeOnCompletion { body?.close() }

        val responseContent = body?.source()?.toChannel(callContext, requestData) ?: ByteReadChannel.Empty
        return buildResponseData(response, requestTime, responseContent, callContext)
    }
    
    private fun BufferedSource.toChannel(context: CoroutineContext, requestData: HttpRequestData): ByteReadChannel =
    GlobalScope.writer(context) {
        use { source ->
            var lastRead = 0
            while (source.isOpen && context.isActive && lastRead >= 0) {
                channel.write { buffer ->
                    lastRead = try {
                        source.read(buffer)
                    } catch (cause: Throwable) {
                        throw mapExceptions(cause, requestData)
                    }
                }
            }
        }
    }.channel

I suppose that

body?.close()

Hi!

Is there a recommended way to handle request errors? There is no mention of errors in client part of https://ktor.io/docs. And in HttpClient.request javadoc there is only minimalistic sentence if fails, an exception is thrown.

We'd like to handle "expected" (IO, bizzare server responses) exceptions and do not handle "unexpected" (programmer errors of any kind in custom features/ktor codebase/3rd party engines, JVM/OS-layer errors).

For some time we lived with the following code:

try {
    httpClient.request { ... }
} catch (e: ResponseException) { ... }
} catch (e: IOException) { ... }
} catch (e: SerializationException) { ... }

and it was fine. But then we found out that NoTransformationFoundException is also possible when server responded with unexpected content-type. Also, in K/N IllegalStateException and MalformedInputException may be thrown. And MalformedInputException does not inherit from Exception (is it a bug, btw? similar jvm exception inherit from IOException). So only catch (Throwable) gives us request that could not lead to application crash.

I am using Ktor as common library for platforms iOS and Android
our backend services are session and cookie based, where I first do authorization call, as response I get token, using that token as cookie header I need to make next consecutive requests for which ktor client is adding encoded value instead of actually passed value for which my backend is not providing valid response, can anyone help me in resolving this, upon verifying using proxy tools, if my backend is expecting AIKOXEyRBSpW8noxNxP0NA..|1636357088|huYnaZ7kpyR5OZ15Svvy5GWoEFg.ktor is passing
AIKOXEyRBSpW8noxNxP0NA%2E%2E%7C1636357088%7ChuYnaZ7kpyR5OZ15Svvy5GWoEFg%2E
Basically its adding different value for special symbols

My code used is as shown below

suspend fun getVersion(token: String): VersionResponse? {
    return try {
        val response: VersionResponse? = client.get {
            url("https://cloudiq.emc.com/api/version")
            val session = "ngssosession=$token"
            println("fafa session - $session")
            headers {
                append("content-type", "application/json; charset=UTF-8")
                append("Accept", "application/json")
                append("Accept-Charset", "UTF-8")
                append("accept-encoding", "deflate, gzip, br, zstd")
            }
            cookie("ngssosession", token)
        }
        response
    } catch (exception: Exception) {
        exception.printStackTrace()
        null
    }
}

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

I am using static roting for folder. On JVM 11 it works properly, but when I am trying to retrieve static data with server on JVM 8, I am getting that stacktrace (pastebin) on the server side and Empty response on the client side (browser)

I get this stacktrace when using Apache, problem happens when switching from 1.6.4 to 1.6.5.

I am using the latest Java 8 JDK, am I forced to switch to more modern JDK?

Describe the bug
"/", "?", "#", "@" symbols in 'Host' parameter value are prohibited(see https://tools.ietf.org/html/rfc2396#appendix-A)

To Reproduce
Steps to reproduce the behavior:
Run code:

import io.ktor.http.cio.parseRequest
import io.ktor.utils.io.ByteReadChannel
import kotlinx.coroutines.runBlocking

fun main() {
    listOf(
        """
        POST / HTTP/1.1
        Host: www/example.com


        """.trimIndent(),
        """
        POST / HTTP/1.1
        Host: www.example?com


        """.trimIndent(),
        """
        POST / HTTP/1.1
        Host: www.ex#mple.com


        """.trimIndent(),
        """
        POST / HTTP/1.1
        Host: www.ex@mple.com


        """.trimIndent()
    ).forEach {
        test(it)
    }
}

fun test(http: String) {
    val request = runBlocking { parseRequest(ByteReadChannel(http)) }!!
    println("method=${request.method};uri={${request.uri}};headers=[${request.headers}]")
}

Expected behavior
An error expected - exception or null result.

There is no description in the documentation of what type of logger is used on different platforms by default, particularly on JVM and POSIX.
The default logger for JVM (Logger.DEFAULT) is an slf4j logger that requires implementation, e.g Logback, and the default logger for POSIX (Logger.SIMPLE) is just a logger that prints everything to stdout.

I can't make 'e2e' to start.

https://github.com/ktorio/ktor-documentation/tree/main/codeSnippets/snippets/e2e

Expected:

./gradlew :e2e:run

This has to work.

If the project's package is com.example.myProject, the generated project will have the source files in e.g.
src/main/kotlin/com/example/myProject/Application.kt

But Kotlin's coding conventions suggests omitting the common root package from the directory structure:
src/main/kotlin/Application.kt

(Application.kt will still have package com.example.myProject at the top of the file, of course)

From Kotlin's coding conventions page:

In pure Kotlin projects, the recommended directory structure follows the package structure with the common root package omitted. For example, if all the code in the project is in the org.example.kotlin package and its subpackages, files with the org.example.kotlin package should be placed directly under the source root, and files in org.example.kotlin.network.socket should be in the network/socket subdirectory of the source root.

Its seems that the publish infrastructure is broken again and
https://search.maven.org/artifact/io.ktor/ktor-client-core-watchosx64/1.6.5
Wasn't published properly. It's however referenced in the module https://repo1.maven.org/maven2/io/ktor/ktor-client-core/1.6.5/ktor-client-core-1.6.5.module

Hi!

In version 1.6.4 there are no problems, tvOS is supported without problems.
When upgrading the version to 1.6.5, it cannot find tvOS support.

Currently, the plugin contains only the Sessions plugin. There is also a separate Session authentication provider: https://ktor.io/docs/session-auth.html

Can we please update the description to the following:

Ktor is a web application framework for creating connected systems. You can use it to create server-side as well as client-side applications. It supports multiple platforms, including JVM, JavaScript, and Kotlin/Native. This plugin provides functionality in the IDE such as creating new projects, plugin configuration, navigation (including URL navigation), refactorings across client and server, migrations, and more!

The rational behind this proposal is that a production deployment of an application shall typically run with INFO threshold on its logs (DEBUG and TRACE are typically used only for debugging of certain subsystems) and we expect that all requests shall be logged in a production deployment by default, since the log of requests represents the starting point for investigation of any production incidents.

Currently, if you use a static file from the JVM resources like this

                static {
                    resources()
                }

and try accessing a file this error get's thrown instead of a 404

I've been trying to get a streaming response working for a while and I don't think it's currently possible to flush response headers before any byte is written when using the netty server engine. The exact same code works perfectly with cio.

The code looks something like this (I've tried using WriteChannelContent with 0-byte writes and explicit flushes as well):

route("/timed") {
    get {
        val byteStream = ByteChannel(autoFlush = true)
        launch(Dispatchers.Unconfined) {
            delay(5000)
            byteStream.writeFully(Charsets.UTF_8.encode("foo\n"))
            byteStream.close(null)
        }
        call.respond(object : OutgoingContent.ReadChannelContent() {
            override val status: HttpStatusCode? = HttpStatusCode.OK
            override val contentType: ContentType? = ContentType.Text.Plain
            override val headers: Headers = Headers.Empty
            override fun readFrom() = byteStream
        })
    }
}

I'm testing with curl -XGET localhost:8080/timed -v. When running the server with CIO this will immediately print the headers and then 5s later it'll print foo and close the response. With netty, this will wait for the full 5s before printing the whole response at once.

Writing multiple messages shows that this is only an issue with the initial header response. Streaming works fine with all messages after the initial byte.

https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS/Errors/CORSNotSupportingCredentials

install(CORS) {
    anyHost()
    allowCredentials = true
}

Expected: IAE during installing CORS plugin with this configuration

When using directorySessionStorage or a custom implementation of SessionStorage, I noticed that every time after the read function is called, the write function is called which invalidates the cache, making the use of the cache completely pointless.

Expected behavior: After the read SessionStorage method is called, the write SessionStorage method is not called.
Actual behavior: After the read SessionStorage method is called, the write SessionStorage method is also called.

Steps for reproduce:

1. Compile and run the code from the snippet

2. Authorize by sending HTTP POST request to http://localhost:9090/authenticate sending body in format x-www-form-urlencoded with user:user password:password, any data are considered correct, should return HTTP Status Code 200

3. Make sure authorization was successful and sending HTTP GET request to http://localhost:9090/hello returns HTTP Status Code 200 and "Hello World!" string.

When sending subsequent HTTP GET requests to http://localhost:9090/hello, the file with information about the session, which will be written to the /tmp folder, will be overwritten each time. Also, in the debugger in the io.ktor.sessions.CacheStorage class, you can make sure that for each request the read method will be called and then the write method will be called.

Code to reproduce the issue:

import io.ktor.server.engine.*
import io.ktor.server.netty.*
import io.ktor.application.*
import io.ktor.auth.*
import io.ktor.http.*
import io.ktor.response.*
import io.ktor.routing.*
import io.ktor.sessions.*
import java.io.File

fun main() {
    embeddedServer(Netty, port = 9090, host = "0.0.0.0") {
        install(Authentication) {
            session<UserIdPrincipal>("auth-session") {
                validate { it }
                challenge { call.respond(HttpStatusCode.Unauthorized) }
            }

            form("auth-form") {
                validate { UserIdPrincipal(it.name) }
                challenge { call.respond(HttpStatusCode.Forbidden) }
            }
        }

        install(Sessions) {
            cookie<UserIdPrincipal>(
                "user_session",
                directorySessionStorage(File("/tmp"))
            )
        }

        routing {
            authenticate("auth-form") {
                post("/authenticate") {
                    val session = call.principal<UserIdPrincipal>()
                    call.sessions.set(session)
                    call.respond(HttpStatusCode.OK)
                }
            }
        }

        routing {
            authenticate("auth-session") {
                get("/hello") {
                    call.respondText("Hello World!")
                }
            }
        }

    }.start(wait = true)
}

    @Test
    fun testChunked() {
        createAndStartServer {
            handle {
                call.respond(object : OutgoingContent.ByteArrayContent() {
                    override val status: HttpStatusCode = HttpStatusCode.OK
                    override val headers: Headers = Headers.Empty
                    override fun bytes() = ByteArray(5) { it.toByte() }
                })
            }
        }

        withUrl("/") {
            assertEquals(200, status.value)
        }
    }

adding override val contentLength: Long = 5 fixes freezing

0. Deduce a set of anchors that may check piepline state
1. Implement anchors API (beforeAnchor / afterAnchor)
2. Each anchor must have its own "receiver type" that will be applied in beforeAnchor / afterAnchor block. It defines which handlers (onCall, onCallReceive, ...) are relevant and present and which are not.
3. Get rid of standard phases, use anchors instead!

• onCallReceive should insert to call receive pipeline
• onCallReceive should insert to the same pipeline but before/after some anchor

Ktor Version
1.6.4

Ktor Engine Used
Netty Server

Behaviour
Only some of NettyApplicationEngine's properties are loaded from ApplicationConfig set when using EngineMain.

Expected behaviour
After reading https://ktor.io/docs/engines.html#configure-engine I assumed it would be possible to configure all properties (besides the functions) via the configuration files.
Missing runningLimit, requestReadTimeoutSeconds and tcpKeepAlive

https://ktor.io/docs/testing.html describes how to send body and how to set headers for test requests; however, there doesn't seem to be a way to programatically set request parameters. It is possible to inline them in URL itself, but it is very inelegant.

If this is desired functionality, I can try sending a PR :)

I haven't checked the details yet but some tests using Ktor's testing module in our project detected a binary-compatibility issue.

• https://github.com/slackapi/java-slack-sdk/runs/4087459078?check_suite_focus=true

As a workaround, we locked the version to 1.6.4 and it worked for us. https://github.com/slackapi/java-slack-sdk/commit/8a9063bf694376074a3a4bed93871416f48241c3

I hope this helps.

The combination from the title is not allowed, as per:

if (configuration.allowCredentials) {
    require(!allowsAnyHost) {
        "AnyHost * is not allowed in combination with Allow-Credentials, see " +
            "https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS/Errors/CORSNotSupportingCredentials."
    }
}

However, while the specific combination of responding with Access-Control-Allow-Origin: * and allowing credentials may be illegal, that doesn't mean it should be impossible to allow any host to perform a request with credentials. All that's needed is responding with Access-Control-Allow-Origin: $requestOrigin if credentials are to be allowed:

private fun ApplicationCall.accessControlAllowOrigin(origin: String) {
    if (allowsAnyHost && !allowCredentials) { // <--- modification here
        response.header(HttpHeaders.AccessControlAllowOrigin, "*")
    } else {
        response.header(HttpHeaders.AccessControlAllowOrigin, origin)
    }
}

(by the way, yes, I am aware of the security implications)

We should drop everything before 1.6.6

The method freezes without response:

public suspend fun HttpClient.webSocketSession(
    block: HttpRequestBuilder.() -> Unit
): DefaultClientWebSocketSession

When the exception fails in:

client.wss {
    error("error")
}

It will be swallowed and can either freeze or fail with unrelated cause.

Distinguishing green, yellow, red.

Right now calling client.ws method without feature triggers failed to convert class exception, it should check for the feature installed and fail early instead

I'm getting some strange behavior when using pebble with 1.6.5. It seems to get caught in some loop when serving pebble content. I confirmed that this behavior does not exist in 1.6.4. I have attached a sample project to this, if you try to hit localhost:8080/ it will reproduce.

The setup is relatively simple, serving just about any pebble file seems to make this crash.

Output after a single call to localhost:8080/

The last sentence is not required and is grammatically incorrect. Let's drop it please.

If the Logging plugin is installed the Ktor client deadlocks/blocks sometimes after BODY START is printed to the console.

The response is still getting returned back to the calling function, but any future requests will block.

It doesn't happen every time, but it is reasonably easy to reproduce it with the attached Sample app.

https://ktor.teamcity.com/buildConfiguration/Ktor_KtorMatrixCoreMacOSJava8/46701?buildTab=tests&status=failed&expandedTest=build%3A(id%3A46701)%2Cid%3A14802

Hi, I'm using Ktor 1.6.4 in a Kotlin Multiplatform project together with the Bearer Authentication feature.

We are logging the user out when the refresh of the token wasn't successful. Our Open ID Connect server responds with a 400 when the refresh token was used before for a refresh. So when there are multiple requests running in parallel the first refresh is successful but the other request already responds with a 401 and the Auth feature tries to refresh with the same refresh token this leads to a 400 error.

Is there something we can do to queue requests or is this the expected behaviour?

install(Auth) {
      bearer {
          loadTokens {
              val tokenData = getTokenDataInteractor.execute() // Get tokens from storage
              if (tokenData.status == SUCCESS && tokenData.data?.accessToken != null) {
                  BearerTokens(tokenData.data.accessToken, tokenData.data.refreshToken ?: "")
              } else {
                  null
              }
          }
          refreshTokens {
              val tokenData = refreshTokenInteractor.execute() // Fetches and stores new token
              if (tokenData.status == SUCCESS && tokenData.data?.accessToken != null) {
                  BearerTokens(tokenData.data.accessToken, tokenData.data.refreshToken ?: "")
              } else {
                  null
              }
          }
      }
  }

Hi! I'm writing a custom feature that saves cookies to a file when the installed HttpClient closes. From reading the HttpClient.close() function here, it seems that the intention is that the close() call will cascade to installed Closeable features; but I discovered that my feature's close() function is not called due to seemingly another layer of indirection in HttpClientConfig.install().

This test below demonstrates the problem:

class FeatureCloseTest {
  @Test
  fun testFeatureCloseIsCalled() {
    val client = HttpClient(MockEngine) {
      engine { addHandler { respond("") } }
      install(TestFeature)
    }
    client.close()
    assert(client.feature(TestFeature)!!.called)  // This fails
  }

  class TestFeature : Closeable {
    var called = false
    override fun close() {
      called = true
    }

    companion object : HttpClientFeature<Unit, TestFeature> {
      override val key: AttributeKey<TestFeature> = AttributeKey("TestFeature")
      override fun install(feature: TestFeature, scope: HttpClient) = Unit
      override fun prepare(block: Unit.() -> Unit): TestFeature = TestFeature()
    }
  }
}

I think this is a bug? I can work around it at the moment to explicitly call my feature's close() function, but it would be good to get this fixed.

This code snippet is allowed, but leads to invalid configuration:

val client = HttpClient() {
    install(JsonFeature) {
        install(Auth) {
            // ...
        }
    }
}

Hi,

It seems that there are performance issues with the current implementation of TCP socket write and also with reading files. Attaching the performance comparison for ktor IO vs regular JVM raw IO:

1. ./gradlew installDist has to be run manually before running docker which seems rather odd considering most use cases are deployment on the cloud.
2. Naming the project docker could be confused with running docker itself

Suggested improved Dockerfile:

FROM gradle:6-jdk8 AS build
COPY --chown=gradle:gradle . /home/gradle/src
WORKDIR /home/gradle/src
RUN gradle installDist --no-daemon

FROM openjdk:8-jdk
EXPOSE 8080:8080
RUN mkdir /app
COPY --from=build /home/gradle/src/build/install/docker/ /app/
WORKDIR /app/bin
CMD ["./docker"]

We need to describe a secure way of storing sensitive data, like credentials, and a way of accessing them in Ktor application.

https://stackoverflow.com/questions/69630762/where-to-save-sensitive-data-for-application-conf-in-ktor-application

https://helpserver.labs.jb.gg/help/ktor/2.0.0/client-retry.html#configure_retry

status() should be property not function. With latest 2.0 it does not compile.

Per Ktor docs https://ktor.io/docs/modules.html, installed plugins should only apply to the module in which they are installed. However we are seeing that if a plugin is installed in one module, but not another, the plugin is executed for requests handled by the module that DOES NOT have the plugin installed.This is either a bug, or the documentation is misleading or incomplete on how to separate plugins for different modules.

Example (source, and runnable JAR provided):

I have a Ktor application with 2 modules, each defining a distinct Route,

module1() /module1

module2() /module2

I have the CallLogging plugin installed in module1, but not in module2

However when making calls to routes in either module the CallLogging plugin is executed:

Calling http://localhost:8080/module1

we see in console, from CallLogging plugin

2021-10-07 10:36:30.671 [eventLoopGroupProxy-4-1] TRACE Application - 200 OK: GET - /module1

Calling http://localhost:8080/module2

we see in console, from CallLogging plugin

2021-10-07 10:37:57.069 [eventLoopGroupProxy-4-1] TRACE Application - 200 OK: GET - /module2

Summary

Attempting to create a starter project using start.ktor.io has a build error by default if you select Authentication OAuth.

Steps to Reproduce

1. Navigate to start.ktor.io
2. Maintain default settings
   1. Gradle Kotlin, Ktor 1.6.3, Netty
3. Add Authentication OAuth Plugin
4. Generate Project
5. Attempt to build project

Detailed Description

The generated project includes a Security.kt in plugins to configure OAuth for Google. Within routing for auth-oauth-google, there is a line of code:

call.sessions.set(UserSession(principal?.accessToken.toString()))

Attempting to then build the project, we get the following error:

> Task :compileKotlin FAILED
e: ...\ktor-sample\src\main\kotlin\com\example\plugins\Security.kt: (42, 30): Unresolved reference: sessions
e: ...\ktor-sample\src\main\kotlin\com\example\plugins\Security.kt: (42, 43): Unresolved reference: sessions

This is due to the following import missing in Security.kt: import io.ktor.sessions.*

Solution

When generating a project with OAuth, include import io.ktor.sessions.* in Security.kt

To reproduce create a project with all features selected and the the following properties:

• Build system: Maven
• Ktor version 1.4.0
• Engine: Tomcat
• Configuration: HOCON file

After project generation, sync fails with the following error:

Could not find artifact org.jetbrains.kotlinx:kotlinx-html-jvm:pom:0.7.2 in kotlinx-html (https://maven.pkg.jetbrains.space/public/p/kotlinx-html/maven)

Also, build fails with an unresolved reference error:

/home/stexe/projects/ktor_plugin/ktor-sample7/src/main/kotlin/com/example/plugins/Sockets.kt:11:24
Kotlin: Unresolved reference: tls

Currently it is not possible to build and test Ktor (server and clients) on Apple Silicon with Xcode 13 and macOS 12. This release removes all x64 frameworks, so every hardcoded macosX64 target has to be replaced. This also applies to curl.

When creating a new Ktor project and targeting Ktor 2.0.0-eap-256, some dependencies are not imported by default in gradle file (despite being marked as needed in Plugins list).
These 3 are the ones that I had to import manually:

1. ktor-server-http-redirect
2. ktor-server-default-headers
3. ktor-server-content-negotiation
