Hello,

On berlin, the cuirass-remote-server process experiences some crashes:

Any idea how to make those backtraces more helpful?

Thanks,

Mathieu

Set COLUMNS=9000, then Guile stop trying to fit them in 80 columns,
it will try 9000 columns instead.

Also, backtraces are clearer for compiled code (avoiding (ice-9 eval)).
Is (cuirass scripts remote-server) compiled to .go?

There's might be guile variable you could set as well (or an argument
to 'backtrace'?), but I forgot the details.

Hello Maxime,

Thanks for the suggestions.

The (cuirass scripts) modules were indeed not compiled, this is fixed
with:
https://git.savannah.gnu.org/cgit/guix/guix-cuirass.git/commit/?id=95c29ab9abcd67ebeeee386ff043a7c52680526e.

I also set COLUMNS=500 with:
https://git.savannah.gnu.org/cgit/guix/guix-cuirass.git/commit/?id=16906595cf4bbeaff31ceaedc14c5443f773293c.

Let's see if the backtraces are now more interesting to read.
