Description Nicolas Adenis-Lamarre 2019-05-21 19:14:19 UTC 
since i upgraded to sdl 2.0.9, i got joysticks events from sdl after the joystick closed event.
it may be considered as a bug.

on batocera.linux, i've done a patch to fix that behavior : https://github.com/batocera-linux/batocera.linux/commit/ed0d55420427f0c117bc6d990b9d2ee4563b49d0

basically,i don't call SDL_JoystickUpdate once the joystick is no more attached.

the call stack is the same as the one reported by retropie here : https://github.com/RetroPie/EmulationStation/issues/552

I believe the fix I just did for Bug #5063 should resolve this specific thing too, except on macOS when not using hidapi. I'll leave this bug open and assigned to me until I clean that out.

Comment 2 Ryan C. Gordon 2020-04-08 03:48:09 UTC 
macOS joystick code does the right thing without this flag, so I've removed it with https://hg.libsdl.org/SDL/rev/99bad97fec09, so this bug can be resolved.

Please reopen if you have any further problems, but I think this should resolve the issue.
