NAME
CatalystX::LeakChecker - Debug memory leaks in Catalyst applications
VERSION
version 0.06
SYNOPSIS
package MyApp;
use namespace::autoclean;
extends 'Catalyst';
with 'CatalystX::LeakChecker';
__PACKAGE__->setup;
DESCRIPTION
It's easy to create memory leaks in Catalyst applications and often
they're hard to find. This module tries to help you finding them by
automatically checking for common causes of leaks.
This module is intended for debugging only. I suggest to not enable it
in a production environment.
METHODS
found_leaks(@leaks)
If any leaks were found, this method is called at the end of each
request. A list of leaks is passed to it. It logs a debug message like
this:
[debug] Circular reference detected:
+------------------------------------------------------+-----------------+
| $ctx->{stash}->{ctx} |
'------------------------------------------------------+-----------------'
It's also able to find leaks in code references. A debug message for
that might look like this:
[debug] Circular reference detected:
+------------------------------------------------------+-----------------+
| $a = $ctx->{stash}->{leak_closure}; |
| code reference $a deparses to: sub { |
| package TestApp::Controller::Affe; |
| use warnings; |
| use strict 'refs'; |
| $ctx->response->body('from leaky closure'); |
| }; |
| ${ $ctx } |
'------------------------------------------------------+-----------------'
Override this method if you want leaks to be reported differently.
