NAME MasonX::LeakGuard::Object - report memory leaks (objects) per request SYNOPSIS use MasonX::LeakGuard::Object; %MasonX::LeakGuard::Object::OPTIONS = ( exclude => [ 'utf8', 'HTML::Mason::*', 'Devel::StackTrace', ], hide_arguments => [ 'pass', 'password', ], ); my @MasonParameters = ( ... plugins => [qw(MasonX::LeakGuard::Object)], ); DESCRIPTION This is plugin for HTML::Mason based applications that helps you find memory leaks in OO code. It uses Devel::LeakGuard::Object framework for that. OPTIONS It's possible to use all options leakguard function in Devel::LeakGuard::Object supports. Look at "SYNOPSIS" for example. Some additional options are supported. on_leak on_leak option can be used to customize report or redirect to custom log, for example: %MasonX::LeakGuard::Object::OPTIONS = ( on_leak => sub { my ($report, %args) = @_; MyApp->logger->error( $args{'message'} ); }, ); First argument is the report structure (read more on it in Devel::LeakGuard::Object). To make life easier more data is passed into your function as a hash. The hash contains: formatted - formatted report, a text table. message - formatted default message containg description, request path, request arguments and report. For example: Leak(s) found after request to '/index.html' with $ARGS1 = [ 'argument', 'value', ]; Leaked objects: Class Before After Delta MyApp::Class 0 1 1 path - request path. arguments - request arguments, array reference. hide_arguments It's possible to specify list of arguments names to hide from reports, for example: %MasonX::LeakGuard::Object::OPTIONS = ( hide_arguments => [ 'pass', 'password', ], ); FALSE POSITIVES It's possible that false positives are reported, for example if a compontent has ONCE block where you cache some values on first request. Most caches will generate false positive reports, but it's possible to use options of function leakguard in Devel::LeakGuard::Object. Look at "SYNOPSIS" for example and "OPTIONS" for additional details. To avoid many false positives the module as well ignores first request to a path. Sure it doesn't protect you from all cases.
