08/29/2019, 10:18 PMman, app code gets real confused when I right click in the editor
er, i don't even see how to run in tests in this thing
k
kpgalligan
08/29/2019, 10:23 PMIn app code?

Kris Wong
08/29/2019, 10:23 PMyeah

08/29/2019, 10:25 PMI don’t know. I would just log before/after freeze and first confirm it is stopping there. The debugger may be tricky to set up for app code tests
k
Kris Wong
08/29/2019, 10:25 PMthat's definitely were it stopped when running in Xcode
let me try just running the app

08/29/2019, 10:25 PMHow do you know if the debugger isn’t working?
k
Kris Wong
08/29/2019, 10:26 PMi know it stopped there, I just can't step into the call to see where it stopped underneath that call

08/29/2019, 10:27 PMThis is just freeze or it’s doing a bunch of threading stuff?

Kris Wong
08/29/2019, 10:27 PMjust freeze

08/29/2019, 10:28 PMYou’re saying if I create an Xcode project and just call freeze on a kotlin object you’d expect it to deadlock?
In a test

Kris Wong
08/29/2019, 10:28 PMwell, the project is much complex than that, but that's essentially what happening
k
kpgalligan
08/29/2019, 10:29 PMI guess I need to see that or I would assume something else is happening.

Kris Wong
08/29/2019, 10:30 PMyeah I am trying to investigate but things are moving very slowly
k
kpgalligan
08/29/2019, 10:30 PMI mean, I’ve had some strange issues with KN, but freeze deadlocking would indeed be a surprise
Freeze itself happens before you’ve shared code with other threads, so in theory it’s not locking on anything. If execution simply stops there, and you’re 100% sure it isn’t a crash or involved in some other form of infinite loop, it would be very interesting to see that in action.

08/29/2019, 10:51 PMwow, this is pretty spectacular
if you have this
actual fun <T> T.freeze(): T = this.freeze()it's very important you also have this
import kotlin.native.concurrent.freeze😂 2

08/29/2019, 10:51 PMah nice
problem solved haha
k
Kris Wong
08/29/2019, 10:52 PMbecause it builds w/o that, and then it's just an infinite loop
that was a fun exercise. thanks fellas.

08/29/2019, 10:53 PMI have done this

Kris Wong
08/29/2019, 10:55 PMit's pretty easy to figure out when you can actually see the stack trace

08/31/2019, 11:00 PMYou can use 'by' to import KN's freeze as e.g. 'freezeNative', then call it. It will be much less error prone.
