Re: exceptions in threads

[Brian Duggan]

Oh, great!  I was running the latest version I saw
listed in 'rakudobrew list-available' which is 2018.10:

~ $ perl6 -v
This is Rakudo version 2018.10 built on MoarVM version 2018.10
implementing Perl 6.c.

thanks!

Re: exceptions in threads

In v6.d this throws the exception:

$ 6 'start die("bye"); sleep 1'
Unhandled exception in code scheduled on thread 4
bye
  in code  at -e line 1


whereas the exception is silently ignored in 6.c:

$ 6 'use v6.c; start die("bye"); sleep 1'

Not sure if this answers your question, as it is unclear from your question on 
which version you are running.

exceptions in threads

[Brian Duggan]

Hi Perl 6 Users,

What's the best way to know that an exception
occurred in another thread, e.g.

$ perl6 -e 'start say("hi"); sleep 1'
hi
$

but

$ perl6 -e 'start die("bye"); sleep 1'
$

I thought maybe $*SCHEDULER.uncaught_handler
would help out here, but it didn't seem to.

thanks
Brian
