1.10.1 on macOS issues

[John Green]

I upgraded  to latest ivy and now when trying to run my app it just freezes my Mac.

I have since set up a new venv and the same issue is happening.

kivy log doesn't get past this

Any help would be great.

Ok so here's what I've found so far.

New venv with python 3 and kivy 1.10.0 and my app opens no problem. Upgrade to kivy 1.10.1 and I get that freezing like in the OP. I have to force quit python or Mac becomes unresponsive. If I downgrade back to 1.10.0 the problem persists making me think it's a dependency or something that is also upgrading with 1.10.1?

I also tested this in Ubuntu last night and I had the same issues.

Anyone have any ideas?

[James Moore]

If you let it run for awhile does it exit with a stack overflow? If the whole system is slowing down then I would guess it’s forcing your machine to run out of memory and swap. Is there anywhere you’re creating a lot of objects in a loop or using tail recursion?

You can try to see if its a recursion problem by setting sys.setrecursionlimit to something lower than the default of 1000.

FWIW I’m doing development on macOS with 1.10.1 and I’m not seeing any problems.

it's difficult to trace any issues without a log to indicate what is going on.

Could you please run with log_level set to trace

python main.py -c "kivy:log_level:trace"

Hi,

Yeah it just runs out of memory and freezes the computer, it won't exit itself. I've checked my loops and theres nothing major there. 

I tried the set recursion and still had the same issue unfortuneately.

Heres the trace, it just hangs at that last one but I don't see anything in that code from kivymd that should be an issue.

OK so turns out to be a rogue bit of code I had added twice by accident.

I just went way back in my git and kept moving forward until it broke.

I must have done it and updated kivy at the same time.

lesson learned .
