NAME

    Dash::Leak - Track memory allocation

SYNOPSIS

    Quick summary of what the module does.

        BEGIN {

            # enables operation of Dash::Leak, leaksz is a nop without this

            $ENV{DEBUG_MEM} = 1;

        }

        use Dash::Leak;

    

        {

            leaksz "block label";

            # some code, that may leak

        }

        # If your code leaked, you'll be noticed about change

        # of process vsize after leaving block

    

        leaksz "tests begin";

        some_operation($arg);

        leaksz "some_operation", sub {

            warn sprintf "We leaked after some_operation($arg) by %+d kilobytes;", shift

        };

        another_operation();

        leaksz "another_operation";

        # ...

        use Dash::Leak sub { ... }; # Will call this cb for every alloc, instead of warn

EXPORT

    Export of this module is "virtual", by using Devel::Declare. When

    $ENV{DEBUG_MEM} is true, it will work, when false, this opcodes will be

    ignored, like with "leaksz ... if 0";

FUNCTIONS

  leaksz $label, [$cb->($delta)]

    Starts tracking current block. If something changed since last note,

    notice will be warned. If callback is passed, it will be invoked instead

    of warn.
