Errors in threads

Hi.
I don't understand why I don't see error messages when running a code
in a thread ?
How could I change that (and stop execution when an error occured in
the problematic thread)?
Thanks a lot.

That's OK, i had only been once again stupid.
The only thing I had to do was running Ruby with -d option...

Another solution is to do Thread.abort_on_exception=true at the top of
your script.

10:34:57 [~]: ruby -e 'Thread.abort_on_exception=false; Thread.new {
raise "foo" }; sleep 5'
10:35:06 [~]: ruby -e 'Thread.abort_on_exception=true; Thread.new {
raise "foo" }; sleep 5'
-e:1: foo (RuntimeError)
from -e:1
10:35:12 [~]:

See

Kind regards
