NAME

Devel::Leak::Cb - Detect leaked callbacks

CONTENTS

VERSION

Version 0.04

SYNOPSIS



    use Devel::Leak::Cb;
   
    AnyEvent->timer( after => 1, cb => cb {
        ...
    });
   
    # If $ENV{DEBUG_CB} is true and callback not destroyed till END, the youll be noticed



DESCRIPTION

By default, cb { .. } will be rewritten as sub { .. } using Devel::Declare and will give no additional cost at runtime

When $ENV{DEBUG_CB} will be set, then all cb {} declarations will be counted, and if some of them will not be destroyed till the END stage, you’ll be warned

EXPORT

Exports a single function: cb {}, which would be rewritten as sub {} when $ENV{DEBUG_CB} is not in effect

If DEBUG_CB > 1 and Devel::FindRef is installed, then output will include reference tree of leaked callbacks
