I think I will need a minimal example, because

renderPresent rendererDoes not seg fault, for me. I'm using an unreleased version of reactive-banana (the gc-new branch) and the new-api branch of SDL2.

threadDelay 500000This is segfaulting for me, compiled with -O0 -threaded. I'm on OSX 10.9.5 using sdl2 2.0.3, commit 99d5e09 of haskell-game/sdl.

Perfect, thank you! I'll see what's up.

Unfortunately I can't reproduce the problem with your paste :( Are you able to obtain a stack trace of the segfault? In Linux I'd recommend running under gdb, but I'm not sure what the OS X equivalent is.

Hmmm, sounds like it could be an SDL bug. Could you try creating a non-accelerated renderer? That would be done by changing out defaultRenderer to something else. You might also want to try specifying windowOpenGL to the defaultWindow config.

Same segfault with UnacceleratedRenderer, and also with windowOpenGL = Core Normal 2 1 (I do have OpenGL 2.1). Shrug!

I confirm being able to reproduce this as well on my OS X computer.
GHC 7.10.2 / SDL2 (SDL2-2.0.3)
I tried your code with stable 2.0.0.
It's not only happening with renderFillRect, but also drawLine. I didn't try others, but my guess is that similar functions behave the same way.
For instance:

I'll see if I can write a similar C program for you guys. With the crash happening at glBegin it makes me think there is something wrong in how we're initializing things... somewhere (or a bug in SDL)

I made a similar code to try with sdl2-1.3.1. And so far it looks similar.

Can you share that code? That will probably help me reproduce the problem as a C example, and then I can open an issue on the SDL bug tracker.

It's kind of ugly, I needed to use void to make GHC compile. Also note that I put SDL.updateWindowSurface inside the thread too. It does not crash when outside, but the display is glitched. In this case the segmentation fault only occurs when both fillRect and updateWindowSurface are inside the same thread.

Ok, I don't think we're going to be able to do anything about this.
https://bugzilla.libsdl.org/show_bug.cgi?id=1995
And
This API is not designed to be used from multiple threads, see this bug for details.

This is what I feared actually. So basically we should keep our rendering on the same thread.

ocharles
commented on May 26, 2024
The same thread you initialize on I believe, though it may be the same thread you create the window on.

akhra
commented on May 26, 2024
Oof. This almost makes me feel like #8 might be worth revisiting, to guarantee the renderer is fed from a single thread without having to ban async.
@phaazon's IORef asset trick also feels relevant here, though I haven't thought it through.

The SDL Wiki appears to be supporting @tejon's suggestion:
The main advice is not to call SDL video or event functions from separate threads. This doesn't
mean you can't call them from a thread, it means you shouldn't have two threads both calling video
functions or handling events. The reason is that the SDL functions aren't designed for threads, so
they don't know how to handle what happens if two video functions occured at the same time.

phaazon
commented on May 26, 2024
Well, my “trick” doesn’t add any kind of thread safety. You can still create the renderer in a specific thread, and pass it to another thread and end up in a dramatic situation.
Maybe you can use universal quantification to disable passing the renderer around and keep it scoped in the calling thread?

All of the tricks of regions and stuff like that add a ton of complexity. I'd rather just document it.

@phaazon I wasn't too clear; my thought was actually to build a wrapper around the renderer and its thread to manage inter-thread communication, and pass that around as an IORef. Like I said though, I really haven't thought it through. :)

Closing as this is just part of how SDL works, unfortunately.
