Promise sometimes is executed asynchronously #3527
Comments
From @bbkrOn Rakudo Star 2014.08: $ perl6 -e 'my $job1 = start { say "started job 1"; sleep 4; say "finished job 1"}; my $job2 = start { say "started job 2"; sleep 4; say "finished job 2"}; await $job1, $job2' In most cases I get expected result: started job 1 But sometimes promises are executed synchronously: started job 1 Looks like they are assigned to the same thread despite other threads being unused. My common-sense assumption was "If I spawn less Promises than available threads they will be ALL executed in parallel". |
From @bbkrOn Rakudo Star 2014.09 with MoarVM promises are executed asynchronously. But i get randomly one of following errors: Unhandled exception: non-invokable object is non-invokable Unhandled exception: Cannot assign to a readonly variable or a value |

The RT System itself - Status changed from 'new' to 'open' |
From @bbkrNew random error after running this code: $ perl6 --version Unhandled exception: Cannot invoke this object (REPR: P6opaque, cs = 0) |
From @bbkrI am no longer getting this bug on: This is perl6 version 2014.10-114-gf8f6feb built on MoarVM version 2014.10-17-g05b25a6 Ticket should be marked as testneeded or just closed? |
From @zoffixznetTests added: Raku/roast@1bf2a1b1a5 |
