Test::Weaken helps detect unfreed Perl data in arrays, hashes, scalars,
|
|
objects, etc, by descending recursively through structures and watching
|
|
that everything is freed. Unfreed data is a useless overhead and may
|
|
cause an application to abend due to lack of memory.
|
|
|
|
Normally if the last reference to something is discarded then it and
|
|
anything in it is freed automatically. But this might not occur due to
|
|
circular references, unexpected global variables or closures, or reference
|
|
counting mistakes in XSUBs.
|
|
|
|
Test::Weaken is named for the strategy used to detect leaks. References
|
|
are taken to the test objects and all their contents, then those
|
|
references are weakened and expected to be then freed.
|
|
|
|
There's options to ignore intentional globals, or include extra associated
|
|
data held elsewhere, or invoke an explicit destructor. Unfreed parts are
|
|
reported and can be passed to other modules such as Devel::FindRef to try
|
|
to discover why they weren't freed.
|
|
|
|
Test::Weaken examines structures to an unlimited depth and is safe on
|
|
circular structures.
