Test::Memory::Cycle - Check for memory leaks and circular memory references VERSION
Version 1.04 SYNOPSIS
Perl's garbage collection has one big problem: Circular references can't get cleaned up. A circular reference can be as simple as two reference 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. FUNCTIONS
"memory_cycle_ok( $reference, $msg )" Checks that $reference doesn't have any circular memory references. "memory_cycle_exists( $reference, $msg )" Checks that $reference does have any circular memory references. "weakened_memory_cycle_ok( $reference, $msg )" 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". "weakened_memory_cycle_exists( $reference, $msg )" Checks that $reference does have any circular memory references, but unlike "memory_cycle_exists" this will also check for weakened cycles produced with Scalar::Util's "weaken".
