Devel::Leak - Utility for looking for perl objects that are not reclaimed. River stage two • 6 direct dependents • 14 total dependents

Devel::Leak has two functions "NoteSV" and "CheckSV". "NoteSV" walks the perl internal table of allocated SVs (scalar values) - (which actually contains arrays and hashes too), and records their addresses in a table. It returns a count of these "thin...

Devel::Cycle - Find memory cycles in objects River stage three • 14 direct dependents • 258 total dependents

This is a simple developer's tool for finding circular references in objects and other types of references. Because of Perl's reference-count based memory management, circular references will cause memory leaks. EXPORT The find_cycle() and find_weake...

Devel::WeakRef - weak references (not reference-counted) River stage zero No dependents

A weak reference maintains a "pointer" to an object (specified by a reference to it, just like "bless") that does not contribute to the object's reference count; thus, the object's storage will be freed (and its destructor invoked) when only weak ref...
