Test::Memory::Cycle - Check for memory leaks and circular memory references
Version 1.06
Perl's garbage collection has one big problem: Circular references can't get cleaned up. A circular reference can be as simple as two references that refer to each other:
my $mom = {
name => "Marilyn Lester",
};
my $me = {
name => "Andy Lester",
mother => $mom,
};
$mom->{son} = $me;
"Test::Memory::Cycle" is built on top of "Devel::Cycle" to give you an easy way to check for these circular references.
use Test::Memory::Cycle;
my $object = new MyObject;
# Do stuff with the object.
memory_cycle_ok( $object );
You can also use "memory_cycle_exists()" to make sure that you have a cycle where you expect to have one.
Checks that $reference doesn't have any circular memory references.

Checks that $reference doesn't have any circular memory references, but unlike "memory_cycle_ok" this will also check for weakened cycles produced with Scalar::Util's "weaken".
