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)]
