Devel::Leak::Cb - Detect leaked callbacks
Version 0.04
use Devel::Leak::Cb; AnyEvent->timer( after => 1, cb => cb { ... }); # If $ENV{DEBUG_CB} is true and callback not destroyed till END, the you'll be noticed
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
$ENV{DEBUG_CB}
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
DEBUG_CB
Create anonymous callback
my $cb = cb {};
Create named callback with static name (Have no effect without $ENV{DEBUG_CB})
my $cb = cb mycallback {};
Create named callback with dynamic name (Have no effect without $ENV{DEBUG_CB}) $name could me only simple scalar identifier, without any special symbols
my $cb = cb $name {}; my $cb = cb $full::name {};
Create named callback with dynamic name (Have no effect without $ENV{DEBUG_CB}) Currently supported only ' and ". Quote-like operators support will be later
my $cb = cb 'name' {}; my $cb = cb "name.$val" {};
You may call C<Devel::Leak::Cb::COUNT()> Manually to check state. All leaked callbacks will be warned. Noop without C<$ENV{DEBUG_CB}>
