Want some fun? Compile the following code and watch your 1.5.0 compiler burn and crash 😄 (already created an issue)

interface A {
    fun a(): String = bu
        "test ${unresolved}"
    }
}

[kralli]

Don’t try it in Intellij though. It will crash too.

[christophsturm]

theres tons of youtrack issues about that and 1.5.10 will hopefully come soon and fix it. in the meantime i use 1.4

[Michael]

some of them even target 1.5.20 as their fix

[christophsturm]

oh. are there different issues? I’m talking about the issue that freezes idea

[Joost Klitsie]

I just tried to copy paste this code to an Android Studio project running 1.3.72 and it crashes

[Joost Klitsie]

I guess it is not just a 1.5.0 thingy 😄

[Joost Klitsie]

Or perhaps android studio uses the 1.5.0 compiler already

[Michael]

Could you send us the error

[Joost Klitsie]

it just hangs

[Joost Klitsie]

on pasting it

[Joost Klitsie]

there is no error

[Joost Klitsie]

completely freezes

[Joost Klitsie]

on restarting android studio it is not pasted in 🙂

[christophsturm]

i pasted it into my project with 1.4.32 and it did not crash.

[christophsturm]

it does not matter what your project uses it just matters what plugin you have installed

[Joost Klitsie]

@christophsturm what is your kotlin plugin version?

[Joost Klitsie]

mine is 202-1.5.0-release-764-AS8194.7

[Joost Klitsie]

I guess it uses that one on the code I try to paste

[Joost Klitsie]

even if my project uses 1.3

[christophsturm]

211-1.4.32-release-IJ7142.27.

[christophsturm]

it keeps offering to update to 1.5.0 which i don’t do

[dmitriy.novozhilov]

This issue is known and already fixed. The problem is in kotlin parser which is same for all language version, so issue depends only on plugin version, not on your project settings

[Joost Klitsie]

for me I have no issues with plugin 1.5 other than pasting this specific code block 😄

[Joost Klitsie]

works like a charm

[christophsturm]

i used 1.5 for a day until i just accidentaly triggered the bug while editing code. so now back to 1.4.32

[dmitriy.novozhilov]

As for workaround you can downgrade to 1.4.xx plugin or download preview plugin for 1.5.10: https://youtrack.jetbrains.com/issue/KT-46455#focus=Comments-27-4893755.0-0

[dmitriy.novozhilov]

for me I have no issues with plugin 1.5 other than pasting this specific code block

This bug was introduced in December. Compiler team uses dev plugins for everyday works which we update to fresh master every two weeks, and the strange (and sad) thing that for all this time no one from us not faced this issue

[christophsturm]

if the last intellij eap cycle would have used 1.5 instead of 1.4.20 it would have been found then

[Joost Klitsie]

@dmitriy.novozhilov I released an app last week that almost brought down our backend as it got stuck in a loop under very specific circumstances and effectively triggered an unwanted load test. Shit happens 🙂 The only thing we can do is learn from it 🙂

[dmitriy.novozhilov]

@christophsturm true story. But recently kotlin IDE plugin codebase was moved from kotlin repo to intellij repo, and it brings some problems with building plugins from unstable idea branch and unstable kotlin branch in the same time

[christophsturm]

ok i guess in the long run it will make exactly that easier, so it will probably not happen again

[kralli]

These things most certainly happen eventually. I actually find these rare occasional bugs somewhat entertaining. Had fun watching Intellij crash several times as I was trying to narrow the cause down.
