Does the normal version of Ktor support the new Kotlin Nativ

Question

Does the normal version of Ktor support the new Kotlin Native Memory Management Model from 1 6 3+ I don t see anything in the changelog

Big Chungus · Answer

What do you mean by normal

ribesg · Answer

As opposed to the eap 1 6 2 version which was specifically made for the new memory model after that I can t find anything about it in subsequent versions

Big Chungus · Answer

Are you talking about ktor client

ribesg · Answer

Well yeah in my case

ribesg · Answer

But you can also use the server in K N so it shouldn t matter

Big Chungus · Answer

I think you should be fine with new mm Ktor server in k n is not released yet and will only come with 2 0

ribesg · Answer

Thanks I ll try the new mm then

Michal Klimczak · Answer

I am trying to make the 2 0 client work with new memory model and having some troubles Right now it s `InvalidMutabilityException mutation attempt of frozen kotlin Array 249bab0` in `kfun io ktor client plugins json serializer SerializerInitializer lt init gt internal + 236` trying to install kotlinx serialization into ktor Using coroutines 1 6 0 native mt fwiw in regular 1 6 0 had other issues works without new mm flag

ribesg · Answer

I m pretty sure coroutines `1 6 0 native mt` isn t meant to work with the new memory model

hfhbd · Answer

Coroutines `1 6 0 native mt` works with the new MM Problems are external dependencies like `io ktor client plugins json` which uses a shared Json instance

Michal Klimczak · Answer

I put my own Json instance to the plugin This happens at the very startup of the app the first time the ktor client is created with the json plugin Any hints what can be done about it

hfhbd · Answer

I think this is useless <https github com ktorio ktor blob b4eba576138372accc299ac8ae2081bb52e6706e ktor shared ktor serialization ktor serialization kotlinx ktor serialization kotlinx json common src io ktor serialization kotlinx json JsonSupport kt L25>

Michal Klimczak · Answer

thinking face I m not using the defaults so that should not affect my code

Michal Klimczak · Answer

okay so I fixed it by removing ```implementation io ktor ktor client serialization $ktorVersion ``` from my iosMain source set was left after migration to ktor 2 x But now I have `kotlin native concurrent InvalidMutabilityException mutation attempt of frozen io ktor client engine engines Node 3d40580` smile

Michal Klimczak · Answer

okay so the thing that fixes ktor and a few other things for me is `kotlin native binary freezing=disabled` in `gradle properties`
