I'm sharing nested hashes. Now when a new element becomes available, the old threads don't see it:
#!/usr/bin/perl
use warnings;
use strict;
use threads;
use threads::shared;
use Data::Dumper;
my $href = &share({});
$href = {};
sub sub1 {
sleep 1;
print threads->tid();
print Dumper $href;
}
$href->{a} = &share({});
$href->{a} = {};
my $th1 = threads->new('sub1');
$href->{b} = &share({});
my $th2 = threads->new('sub1');
$th1->join();
$th2->join();
New th2 sees all values, whereas old th1 only sees the first one:
1$VAR1 = {
'a' => {}
};
2$VAR1 = {
'a' => {},
'b' => {}
};
