I think restart a service is easiest right now. It starts instantly, so not much of a problem really.

any plan to fix http2? https://github.com/ktorio/ktor/issues/350

Yeah, weird… I have kotlinx-coroutines as an explicit dependency, and when I say use 0.25.0, it fails. When I remove that as a compile dependency, the build goes through…

Is there no kotlinx-coroutines-io:0.25.0? I see coroutines-core, and coroutines-jdk8:0.25.0, but coroutines-io is only at 0.24.0…

That might be a question for #coroutines

@mkporwit @bdawg.io Module

kotlinx-coroutines-io

has been moved to

kotlinx-io

https://github.com/Kotlin/kotlinx-io Use

compile 'org.jetbrains.kotlinx:kotlinx-coroutines-io:0.1.0-alpha-4'

From a thread in #coroutines

HI there, is there a completely non-blocking way to download a url to a file with the ktor client?

so i finally figured out whats wrong with tomcat and the nginx reverse proxy what i do not get is why chunked-transfer encoding is only broken on responses that use

respondHtml {...}

Can you get Ktor to work with Kotlin 1.3-M2?

Anybody experienced this problem ?

I have Emails feature, that sends emails via smtp. What is the right way to mock it for tests ? I thought I would create MockEmails feature and replace it with the same AttributeKey, but it is not allowed.

I found the solution. Application has awesome method

uninstallFeature()

When load testing with Ktor with Netty as engine I get the following message:

[nettyCallPool-4-20] WARN io.netty.channel.nio.NioEventLoop - Selector.select() returned prematurely 512 times in a row; rebuilding Selector io.netty.channel.nio.SelectedSelectionKeySetSelector@61246795.

What does this exactly mean? I use the following for testing:

ab -k -n 100000 -c 500 <http://localhost:8080/test>

I only get this result with Keep-Alive enabled

i cannot use

ktor-client-cio

righ now anyway because i use 1.3-M2, but i plan to.. so i have some questions can it open a connection and keep it open for data to come in? the api sends data whenever a chatmessage happens on the bridge.. and almost all other more advanced http clients autoclose connections for me and it is a lot more work than to just implement it in java stdlib (ugly but works) thats not gonna work going forward since i plan to try to minimize jvm specific dependencies though

that said i have not looked much at the api but something in the spirit of

"<http://url.com/stream>".getChunked()
.onChunk { body: String ->

 }
.holdConnection()

would be nice..

Yes, you can use request pipeline interceptor

does OkHttp client has non blocking api?

❓ Does anybody use

Fallback

phase? We are thinking of deprecating it

What does that phase even mean? 🤔😅

📣 API documentation website now available: https://api.ktor.io/0.9.4/

Is the new routing

Location

api able to be used with

io.ktor.websocket.webSocket

?

ktor-http but it says ktor-client.. which gradle does not resolve

btw ktor is ok for serving static content or being a reverse proxy: on the benchmarks for 200 concurrent requests on large css files, nginx did 45ms per request and ktor over netty ~85ms, in real world it would be behine some CloudFront or another CDN caching layer, so the difference is negligible working as a reverse proxy ktor has almost the same performance as nginx. anyway Netflix’s Zuul 2 works the same way, so ktor/netty could also work at the large scale 😄

there should be a way to use json with just kotlinx-serialization .. and for that there needs to be a module that adds this:

package io.ktor.client.features.json

import io.ktor.client.features.json.serializer.KotlinxSerializer

actual fun defaultSerializer(): JsonSerializer = KotlinxSerializer()

so.. aout making ktor-client and kotlinx-serialization support lists, sets, arrays etc.. apparently you can construct those serializers easily, but when calling get<List<Something>> the type will be erased anyway.. but i also do not want to add overloads for list, array, set for every function? i hope i am overlooking some simpler solution that you can shove my nose into 😛

ok so.. basically.. the TypeInfo stuff is only available on the jvm so i could make this jvm specific... or keep it at its current state

well until i can figure out how to undo the magic type erasue on native there is not much of a point in poking around, i will make my version of it work jvm specific for now

well this is horrifying.. i hope kotlin will allow me to do that cleaner and crossplatform..

override suspend fun read(type: TypeInfo, response: HttpResponse): Any {
        val reified = type.reifiedType
        if(reified is ParameterizedType) {
            val arguments = reified.actualTypeArguments
            val first = arguments.first()
            if(first is WildcardType) {
                val upperFirst = first.upperBounds.first()
                println("upper bound: $upperFirst")
                println("upper bound::class ${upperFirst::class}")
                val kclass = kotlin.jvm.internal.ClassReference(upperFirst as Class<*>)
                val serializer = when {
                    type.type == List::class -> kclass.serializer().list
                    type.type == Set::class -> kclass.serializer().set
                    else -> {
                        throw IllegalStateException("WildcardType '${type.reifiedType.typeName}' is not implemented")
                    }
                }
                return json.parse(serializer, response.readText())
            }
        }
        return json.parse(type.type.serializer(), response.readText())
    }
