Warning: socket.send() raised exception [asyncio]

[gaussandhisgun]

So I'm using this from an AUR package on Arch Linux, with ArmCord flatpak and arRPC (but this also happened to me back when i was using the normal discord app from base repos). After some time and probably some resource usage, the script just starts doing... this.

I can CTRL-C out of the script (and it floods my terminal with asyncio errors if i do that), launch it again and keep going, but that needs manual intervention. Maybe there should be a way to auto-restart the script if this kind of thing happens? Like, the script does not stop on these exceptions, but it also does not function until a restart.

This is the commit the AUR package is based on.

Perhaps there could be a change in the code where the tool closes upon an exception rather than remaining open. 🤔

Discord-py-interactions does something like that. If a connection error occurs, then the Python program should be terminated. If you wish to keep it running in the event of a terminating exception, then you'll need an external script that will do that for you.

Although, that shouldn't really be the focus. The focus probably should be why this happens. It may be useful if you go to your configuration file (if it exists) and set the debug variable to true. It should look like this:

config.toml

[global]
debug = true

After that, send the error message here.

Is there also a specific exception mentioned somewhere?

[FichteFoll]

Just in case this wasn't obvious already, error handling is … not exactly the forte of this project. Partially because I personally didn't run into many but also because even when running into them, I wasn't sure what exactly to do to remedy the situation. Close the connection and try to start over? Close the application with an exit code to signal errors (and make the systemd unit fail)? Provide configuration for retries? Those are all questions I didn't want to answer back in the day and haven't really looked into again since.

I'll see if I can find some time in the coming weeks to overhaul the code since there are quite a few thinks I've learned since 2018.
