Postman doesn't allow for concurrent requests right? I remember needing to make concurrent requests but couldn't do it via postman

@asad.awadia I believe for concurrent calls you have to use a tool like Apache JMeter which also would benefit you when you do your load testing for APIs etc

@cedric: I think you're thinking of "Insomnia"

greetings colleagues! i have such file (simplified):

@Entity
data class User(val id:Long) {
    @Transient private val chunks = Set<String>()   // this is always null when read from db
}

I use

spring

,

hibernate

and

kotlin-jpa

plugin. When i read data from db with

spring-data

the

User

entity has all filled columns from the table. All good except that transient

chunks

property. It is always null. As i understood

kotlin-jpa

plugin generates empty constructor and uses it on entity instantiation. But the

chunks

property initializes itself in normal constructor. Is there any workaround how can i initialize transient property?

@deviant I'm not following your code here... What type is chunks on the database?

it is transient so should't be in the db. i's just temporary state of the object

Yeah well... That's what I thought, that's why I didn't understand where the null is coming from

On a side note, I never used kotlin-jpa with Spring Data... So I can't really tell what it is doing.

i guess it just generates an empty constructor

i've done a workaround:

@Transient private var _chunks: MutableSet<Int>? = null
private val chunks: MutableSet<Int>
    get() {
        if (_chunks == null) _chunks = HashSet()
        return _chunks!!
    }

looks ugly. hope somebody suggest me a better solution

I copied your code (no annotations though) and it didn't compile actually... data class User(val id: Long) { private val chunks = Set<String>() } Error:(24, 26) Kotlin: Interface Set does not have constructors

@Marcelus Trojahn uploaded a file: Untitled

i used HashSet

ok. i should read the docs next time 🙂

Enable invokeInitializers option if you want the plugin to run the initialization logic from the synthetic constructor.

👮‍♂️ I don’t see how it relates to #server

Hi guys! I'm new with backend development and I'm trying to create a broadcast communication with a server and my apps when I run this server in a linux OS works but in a windows it just don't send the package, could you help me?

try {
            clientSocket = DatagramSocket()
            val ipAdresses = InetAddress.getByName(getBroadcast())
            val sendData = ByteArray(1024)
            clientSocket?.send(DatagramPacket(sendData, sendData.size, ipAdresses, dstPort))
            clientSocket?.close()
        } catch (e: Exception) {
            if (clientSocket != null) clientSocket?.close()
        }

I've already check this ipAddresses and it's correct for linux and windows and it doesn't generate any exception =/

and I had already turn off my firewall to test and it just doesn't send any data.

How are you verifying that it didn't send the package?

Sorry, I formulated this wrongly... I don't know if the package is not being sent but my clients don't receive these packages if server is running on windows

🚓 I don’t see how it is related to Kotlin

I'm new in Slack

Hello, I'm trying to build my kotlin package with gradle. I've setup the build.gradle as follows

buildscript {
    ext.kotlin_version = '1.2.21'

    repositories {
	    jcenter()
    	mavenCentral()
    }

    dependencies {
	classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
	classpath "org.jetbrains.kotlin:kotlin-stdlib"
    }
}

plugins {
    id "org.jetbrains.kotlin.jvm" version "1.2.21"
}

sourceSets {
    main.kotlin.srcDirs += "./"
}

I'm getting errors related to

kotlin-stdlib

like

Slack Conversation

I'm able to compile this code without issues with the

kotlinc -include-runtime

command

The

classpath "org.jetbrains.kotlin:kotlin-stdlib"

dependency should be in a

dependencies

section, not inside

buildscript/dependencies

.
