| Subject: | Nodes appear to unblessed after using connected_graph() |
JHI,
This bug is similar to 17108 but concerns connected_graph(). This is an interesting one
because it looks like some vertices are objects and some are not:
use strict;
use Graph;
use Digest::MD5;
my $g = Graph::Undirected->new;
my $v1 = Digest::MD5->new();
my $v2 = Digest::MD5->new();
my $v3 = Digest::MD5->new();
my $v4 = Digest::MD5->new();
$g->add_vertices($v1,$v2,$v3,$v4);
$g->add_edges([$v1,$v2],[$v3,$v4],[$v3,$v2]);
my $v = $g->random_vertex; # OK
check($v);
my $cg = $g->connected_graph; # NOT OK
my @vs = $cg->vertices;
for (@vs){
check($_);
}
sub check {
my $md5 = shift;
$md5->add("ljdfgljfglj");
print $md5->hexdigest,"\n";
}
