NAME

DBIx::Class::QueryLog::NotifyOnMax

VERSION

version 1.005001

SYNOPSIS

 my $schema = ... # Get your schema!
 my $ql = DBIx::Class::QueryLog::NotifyOnMax->new(
   max_count => 100,
 );
 $schema->storage->debugobj($ql);
 $schema->storage->debug(1);
   ... # get warning when you do more than 100 queries

DESCRIPTION

More than once I've run into memory leaks that are caused by the user using DBIx::Class::QueryLog and forgetting to call "reset" in DBIx::Class::QueryLog. This subclass of DBIx::Class::QueryLog simply warns after 1_000 queries have gone through it. If you want to do something more complex, subclasses which override the "notify" method are a good idea.

METHODS

new

Overridden version of "new" in DBIx::Class::QueryLog, simply adds an optional max_count parameter which defaults to 1_000.

notify

This is the method that runs when the max_count has been exceeded. Takes no parameters. Make sure to call $self->notified(1) if you want the event to only take place once after the threshold has been exceeded.
