recursive blocking wait detected への対処 - Pixel Pedals of Tomakomai

連休の非同期祭も(疲れたので)これでラストです。 AnyEvent(5.2)でこんなコード書くと、「recursive blocking wait detected」が出ます。 use strict; use warnings; use AnyEvent; sub main { foreach my $i (1 .. 5) { my $cv = AE::cv; my $t = AE::timer $i, 0, sub { $cv->send($i); }; print $cv->recv, "\n"; } } my $t = AE::timer 0, 0, \&main; AE::cv->recv; # 結果 # EV: error in callback (ignoring): AnyEvent::CondVar: recursive blocking wait detected at
