SYNOPSIS

12           package MyApp;
13           use namespace::autoclean;
14
15           extends 'Catalyst';
16           with 'CatalystX::LeakChecker';

DESCRIPTION

21       It's easy to create memory leaks in Catalyst applications and often
22       they're hard to find. This module tries to help you finding them by
23       automatically checking for common causes of leaks.
24
25       This module is intended for debugging only. I suggest to not enable it
26       in a production environment.

METHODS

29   found_leaks(@leaks)
30       If any leaks were found, this method is called at the end of each
31       request. A list of leaks is passed to it. It logs a debug message like
32       this:
33
34           [debug] Circular reference detected:
35           +------------------------------------------------------+-----------------+
36           | $ctx->{stash}->{ctx}                                                   |
37           '------------------------------------------------------+-----------------'
38
39       It's also able to find leaks in code references. A debug message for
40       that might look like this:
41
42           [debug] Circular reference detected:
43           +------------------------------------------------------+-----------------+
44           | $a = $ctx->{stash}->{leak_closure};                                    |
45           | code reference $a deparses to: sub {                                   |
46           |     package TestApp::Controller::Affe;                                 |
47           |     use warnings;                                                      |
48           |     use strict 'refs';                                                 |
49           |     $ctx->response->body('from leaky closure');                        |
50           | };                                                                     |
51           | ${ $ctx }                                                              |
52           '------------------------------------------------------+-----------------'
53
54       Override this method if you want leaks to be reported differently.
