Tuijam crashes with address boundary error

[emdash-ie]

I’ve installed tuijam on a raspberry pi, and I’m getting an error when I run it. The error seems to come from urwid somehow, but tuijam first fails to restore the queue and recently played, and I’m not sure why that is.

Hi @undergroundquizscene. Can you supply the log file from when the app fails to load properly? It should be

$HOME/.config/tuijam/log.txt

Also, it may be helpful to know a bit more about your system. What OS/Distro are you running and what terminal application?

[emdash-ie]

Sorry, I should have provided more info – I wasn’t sure what would be helpful.

The OS is Raspbian 9 (stretch).
The shell is fish, but I’m connecting over ssh from a macbook (using Terminal).

The log file is below. Am I missing some dependencies?

I don't see anything in the logs that indicates a missing dependency. The "failed to load queue/history" is expected since, presumably, you haven't been able to run the app to ever create the queue/history files. Also, the business with the ModuleNotFoundError in the googleapiclient is normal.

The warnings about the signal assertions failing is worrying, but I'm not certain how to address it. I wonder if Linux on the Raspberry PI somehow has different interrupts?

Could you try running it in either bash or zsh? Maybe fish is doing something a little wonky that urwid doesn't like.

Could you also try running some of the urwid examples to see if urwid itself is the issue or possibly the way I'm using it.

Sorry for the delay getting back to you. Running under bash produces what seems to be the same error:

enabling external control.

Segmentation fault

I tried about 10 of the urwid examples and they mostly worked correctly. In the palette_test.py example, selecting 24-bit colour crashed the program with a KeyError, but I don’t think that’s related.

Hi @undergroundquizscene . I'll see if I can get my hands on a raspberry pi to see if I can reproduce this error, but in the meantime, you could try to disable the SIGINT interrupt handling here:

https://github.com/cfangmeier/tuijam/blob/master/tuijam/app.py#L684

You won't be able to exit tuijam (cleanly) with Ctrl-C, but it may fix your problem.

No rush, thanks for looking in to it.

I tried disabling the interrupt handling as you suggested, and as far as I can see I'm getting the same error, unfortunately.
